The Correct Method for Giving a Car a Jump Start

When you need to jump-start your automobile, you will require two things: jumper cables and another vehicle.

Calling a local business that jump-starts vehicles are an additional choice you have.

Now, if you have access to a second vehicle as well as jumper cables, please follow these instructions:

  • In the best-case scenario, you will park the vehicles such that they face each other or park them exactly next to one another. Check to see that the vehicles have been turned off and that the parking brakes have been applied.
  • When you have located the batteries in all of the vehicles, open the hoods of the vehicles and remove the plastic hoods to reveal the battery terminals.
  • Check to see that both the positive and the negative terminals are clean and free of any corrosion.
  • First, you will need to secure the red clamp around the positive post of the dead battery.
  • After that, connect the second red clamp to the positive terminal of the battery that has been charged.
  • After that, connect the negative terminal of the charged battery to the clamp that is black in color.
  • Last but not least, fasten the second black clamp to any section of the deceased car’s frame that has unpainted metal.
  • Once you have secured the clamps to their respective positions you’ll want to start the engine of the vehicle with the functioning battery. After you have done that, you will be able to start the engine even though the battery is dead.
  • After allowing the cars to operate for a short while in this configuration, remove the clamps in the order that they were installed.
  • The engine of the car should be kept running for at least ten minutes after it has been restarted. For more information on the recommended times, please refer to the owner’s manual of your vehicle.

What are the steps involved in Jump Starting a Toyota hybrid vehicle?

Before you get started, you will need to ensure that both vehicles are switched off and parked securely.

Step 1:

Lift the hood of the vehicle and look for the Jump Start Terminal under the lid of the fuse box.

Step 2:

Make the connection between the positive terminal and the red positive jumper cable.

Step 3:

Join the second red positive jumper cable to the positive battery terminal of the vehicle that is providing the jump start.

Step 4:

Establish a connection between the car that is providing the jump start’s negative battery terminal and the black negative cable clamp.

Step 5:

Connect the second negative clamp to a point on the object that is a solid metallic point that has not been painted and that is out of the way.

From this vantage point, all that is required of you is to start the engine of the vehicle that will be providing the jump and allow it to run for approximately five minutes.

After that, you can power up the Toyota hybrid and watch for an indicator that says “Ready” to light up.

After that, you are free to disconnect the jumper cables by doing so in the opposite sequence in which they were attached.

Causes Why Toyota Avalon Won’t Start and Solutions

The most common causes that prevent your Avalon from starting normally are a dead battery in the key fob, a dead battery in the 12-volt battery, corrosion on the battery terminals, a faulty alternator, a clogged fuel filter, a broken starter, a blown fuse, an immobilizer error, an empty gas tank, and any fault in the electrical system.

1. An Inadequate Battery

If the engine in your Avalon won’t turn over or turns over very slowly, the problem is very always caused by a 12v battery that is either dead or in poor condition.

If the further investigation and a voltage test on the battery are carried out, it will become clear whether or not the starting problem is caused by the battery.

A test can be carried out to determine the state of the starter battery, check the level of acid in the battery, and measure the voltage that exists between the two poles.

If a brand-new battery has recently been put in a vehicle, there is a chance that the battery has not yet achieved its maximum capacity. There is no cause for alarm at this time.

A brand-new battery won’t reach its maximum capacity until it has been used for some time.

Test 12v battery

Using a multimeter, you’ll be able to get an accurate reading of the voltage coming from the battery in your Toyota Avalon.

The voltage range of the battery is selected on the multimeter before the test, and the positive and negative poles of the battery are connected to the multimeter.

The results of a successful test of the automobile battery, also known as checking the voltage, are typically values in the range of approximately 12 to 13 volts.

If the reading is higher than 14 volts or lower than 11.5 volts, you need to have the battery condition professionally evaluated.

Because it is possible that the battery has a flaw given these measured numbers, and it will need to be changed.

You may easily jump-start your Avalon if the dead battery is the cause of its failure.

All you need are jumper cables and a healthy battery from another car; alternatively, you can use a battery booster if you have one handy.

Before connecting the red wire to the positive terminal of the donor battery, you must first connect it to the positive terminal of the Avalon battery that has died.

After that, attach the black cable to the negative terminal of the donor battery, and then connect the other end of the wire to the bare metal in the engine compartment of your Avalon.

First, start the vehicle that is being donated, then your Avalon.

Take the cables out of the wall in the opposite sequence.

2. The battery has developed corrosion

As a result of corrosion on the contacts of your vehicle’s battery, you will experience a loss of contact and a reduction in the flow of current, which will prevent your engine from starting in the correct manner.

You need to inspect the battery contacts in your Avalon in order to determine whether or not the starting troubles are caused by filthy battery contacts.

If you pull up the two rubber covers that are covering the battery terminals, you will be able to inspect the terminals for any signs of corrosion.

If you see white deposits or deposits that have a silvery-green color to them, but there are no other cracks or damage, you do not need to replace the battery; you just need to clean it.

Remove rust from the battery.

When you want to clean the batteries in your Toyota Avalon, you have to first remove the pole cables, which does not require any particular expertise but does require some concentration because the order in which you do things is quite crucial.

Before you do anything else, disconnect the black line from the negative pole.

Pliers can be used to release the clamp on the pole even if it is quite secure.

If you choose to use metal pliers despite our advice to the contrary, you are responsible for ensuring that you do not touch any other areas of the body while using them.

After that, you can unplug the red cable that is connected to the positive pole.

Once the corroded battery has been disconnected from the circuit, you can begin cleaning the terminals on the battery.

After you’ve cleaned them, you should reconnect the terminals.

3. Weak key fob battery

If your Avalon has a push start/stop button, then there is a possibility that your vehicle will not start because the battery in the key fob is weak.

You need not worry; even if the battery dies, you will still be able to start your vehicle because it is simply utilized to deliver the signal for locking and unlocking the door.

If the battery in the key fob is depleted, the door will not lock or unlock automatically when the button is pressed.

After that, one will need to manually open the doors.

An inactive transponder serves as the controller for the immobilizer. The fact that the transponder in the key does not require its own independent power supply is one of the meanings of the word “passive.”

How to jump-start a Toyota Avalon when the battery in the key fob is dead

If your model of Avalon only has a key fob with a start/stop button and nowhere to insert a key, then you will need to replace the key fob.

Start the vehicle after positioning the key fob so that it is as close as possible to the start/stop button, and then proceed to start the vehicle.

If it doesn’t work, look in the owner’s handbook of your vehicle for the specific location of where the key fob is supposed to be placed.

This may be different depending on the model.

4. Broken starter motor

Your Avalon’s engine requires a motor called a starter in order to be started.

If the engine is started more frequently, the starter motor will only have a life expectancy of roughly 100,000 to 150,000 miles on average, and this life expectancy will be lowered.

In any event, due to the fact that the starter motor also has a finite lifespan, it is inevitable that it will fail after an extended period of time spent driving the vehicle.

If the starter motor fails, the engine will not start.

Symptom: When you turn the key to start the engine of your Avalon, you will hear a clicking sound.

This clicking sound is the sound of a malfunctioning starting motor.

Also, if the starter motor does not work despite having a good battery, you should suspect that there is a problem with the starter.

When the starter fails to function properly, it is typically necessary to replace it with a whole new unit.

Alternate solution for the starter

If the starter is the problem and the engine won’t start, you can try turning the key while hitting the starter motor with anything like a stick or a metal tool to see if it helps.

If the starter is the problem, the engine won’t start.

This workaround is helpful in situations in which the components that make up the starter are jammed together or in which the gears are slightly misaligned.

However, it is possible that the starter is nearing the end of its life, and as a result, it is recommended that you get it inspected at a dealer or repair shop in order to exclude this possibility.

5. Alternator with a malfunction

A generator is a device that creates electric current; an alternator is a type of generator. In the event that the alternator in your Avalon fails, the vehicle will not be able to generate energy, which will prevent the battery from being charged.

Therefore, even if you believe that a dead battery is the cause of the engine not starting and you replace the battery, the battery will soon die and the engine will not start.

This is the case even if you think that a dead battery is the cause of the engine not starting.

Alternators are incredibly reliable and rarely fail.

Modern automobiles, in particular, have increased performance, which is why it is said that modern automobiles will endure between 200,000 and 300,000 miles.

In spite of this, it is possible for it to become damaged depending on how you use it, and if you buy a secondhand car, the alternator may already be pretty old.

Maintain a high level of vigilance.

In the event that the alternator fails to function properly, it will need to be replaced with a brand-new alternator.

6. Clogged fuel filter

Even though it is not a moving item, the gasoline filter in your Avalon will eventually become clogged due to the accumulation of dirt and other airborne particles.

This process takes place over time.

When this happens, the permeability of the filter decreases, and the fuel pressure also falls.

The degree to which this makes a difference is debatable; nonetheless, if the gasoline filter is excessively clogged with debris, the engine will no longer operate at its maximum capacity, and in rare cases, it may not even start at all. It is not possible to clean the filter; all that can be done is replace it.

7. Fuel pump failure

If the gasoline pump in your Avalon stops working, the vehicle’s engine won’t turn over. In a normal situation, the pump is responsible for ensuring that the required quantity of fuel is transferred from the tank to the injection system of the engine at the appropriate pressure.

In most cases, warning signs will appear well in advance of your fuel pump’s complete failure to function.

For example, if your vehicle’s engine stalls intermittently, starting the vehicle is difficult, the engine jerks slightly, or the engine’s performance decreases, you should have your fuel pump inspected.

It’s possible that this is due to the pump becoming worn out or contaminated.

The gasoline pump is typically noticeable before it completely fails in the event that it is leaking, that a power contact is broken, or that a line or a pump lever is broken. The faulty fuel pump can be replaced in your workshop if you choose to do so.

8. A burned-out fuse

In extremely unusual instances, the malfunction in your Avalon could have been caused by a fuse that blew out.

In order to start the engine, you need to make sure that all of the fuses in the fuse box are in working order.

But exercise extreme caution if you decide to give the fuse box a hand yourself!

Because the box is powered on, any testing or repairs that need to be done must always take place in a workshop.

9. Spark plugs that aren’t working properly

The engine will not start if the spark plugs are not in good working order.

The spark plugs themselves are rarely impacted when there is a problem with the vehicle. Instead, the ignition system’s plug connections become unfastened and loose.

If only one of the plugs is genuinely coming loose, you should be able to solve the problem on your own right there.

A spark plug that has malfunctioned needs to be replaced in the workshop as soon as possible.

10. Rodent damage

The fact that your Toyota Avalon won’t start could also be due to damage caused by rodents.

The animals will get underneath the car and chew their way through the wires and cables.

In theory, this may damage any and all of the vehicle’s systems, including the supply of fuel, the supply of lubricant, or provision of power.

In most cases, the damage caused by rodents is immediately apparent when inspecting the engine area.

In the workshop, we have the means to repair the damage that was caused by the rodent’s bite.

Be ready to pay relatively high prices in this location.

11. Engine failure

Even though it happens extremely infrequently, it has the potential to be the reason why your Avalon stops working.

If a car’s engine stops working, then nothing else on the vehicle will either. It is not unheard of for the operator of a motor vehicle to be held liable for damages of this nature.

The most common causes include a ripped timing belt, improper fueling, an inadequate amount of oil, hydrolock, an overheated engine, and continuous running in an excessive speed range.

In a repair shop, the diagnosis of engine failure requires the expertise of a seasoned mechanic.

Use OBD2 scanner for diagnosis

Due to the fact that the Toyota Avalon is outfitted with onboard diagnostics (OBD), a fault diagnosis might provide the first indicators as to the location of the malfunction.

You have to first connect the diagnostic tool to your Avalon before beginning the troubleshooting process.

The OBDII connector is often found beneath the dashboard in most vehicles.

Turning on the ignition is the next step once the wire has been attached.

However, you must take care not to start the engine.

After then, the majority of diagnostic equipment will inquire about various aspects of the car.

It is essential that you enter this information correctly one hundred percent of the time; otherwise, the outcome of the search could be manipulated.

In most cases, you will also need to fill in the engine and vehicle identification number in addition to the brand and model of the car.

Always double check the facts to ensure that you are getting the most accurate diagnosis possible.

  • Toyota RAV4
  • Toyota Corolla/Toyota Corolla Hatchback
  • Toyota Crown
  • Toyota Camry
  • Toyota Tacoma
  • Toyota Land Cruiser


There are a lot of things that could be preventing your Avalon from starting.

When looking for the reason of the problem, it is best to apply the principle of elimination and begin by ruling out the most obvious cause, which in this case would be a dead battery.

In any event, it is recommended that non-technical people call a breakdown service or a workshop for assistance.

In the case that there is a flaw, the latter can start the repair process on their own.

FAQ on How To Jumpstart A Toyota Avalon

Why won’t my Toyota Avalon turn over and start?

A dead battery, a problem with the alternator, or a starter that has failed are the three most typical reasons why a Toyota Avalon will not start.

How do you go about charging the battery in a Toyota Avalon?

Check to see that the charging device is turned off. Establish a connection between the positive terminal on the battery and the positive cable on the charger. Establish a connection between the negative terminal on the battery and the negative cable on the charger. Adjust the charger so that it charges at the slowest possible rate.

How many times is a car battery capable of being jumped?

How many times is a car battery capable of being re-started with a jump starter? According to Pep Boys, it is fine to use another vehicle’s battery to jump-start a dead car’s battery once, but you shouldn’t try to crank the dead car’s engine more than three or four times in a row if it won’t start. Jump-starting a car can be dangerous. If the dead automobile won’t start, the battery may require further time to charge before it can work again.
