If you lose your keys

New genuine Lexus keys can be made by your Lexus dealer, using the other keys and the key number stamped on your key number plate.

If communication between the electronic key and vehicle is inter- rupted  or the electronic key cannot be used because the bat- tery is depleted, the smart access system with push-button start and wireless remote control cannot be used. In such cases, the doors can be opened or the engine can be started by following the procedure below

- Stopping the engine
Shift the shift lever to “P” and press the “ENGINE START STOP” switch as you normally do when stopping the engine.

- Replacing the key battery
As this above procedure is a temporary measure, it is recommended that the electronic key battery be replaced immediately when the battery depletes.

- Alarm
Using the mechanical key to lock the doors will not set the alarm system.

If a door is unlocked using the mechanical key when the alarm system is set, the alarm may be triggered.

The following procedures may be used to start the engine if the vehi- cle’s battery is discharged.

You can also call your Lexus dealer or qualified repair shop.

If you have a set of jumper (or booster) cables and a second vehicle with a 12-volt battery, you can jump start your Lexus following the steps below.

Connect the jumper cables.

- Starting the engine when the battery is discharged
The engine cannot be started by push-starting.

- Avoiding a discharged battery
l Turn off the headlights and the audio system while the engine is turned off.

l Turn off any unnecessary electrical components when the vehicle is run- ning at a low speed for an extended period, such as in heavy traffic, etc.

- Charging the battery
The electricity stored in the battery will discharge gradually even when the vehicle is not in use, due to natural discharge and the draining effects of cer- tain electrical appliances. If the vehicle is left for a long time, the battery may discharge, and the engine may be unable to start. (The battery recharges automatically during driving.)


- Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam- mable gas that may be emitted from the battery.

l Make sure the jumper cable is connected to the correct terminal and that it is not unintentionally in contact with any part other than the intended ter- minal.

l Do not allow the jumper cables to come into contact with the “+” and “-” terminals.

l Do not allow open flame or use matches, cigarette lighters or smoke near the battery.

- Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while related parts contain lead and lead compounds. Observe the following pre- cautions when handling the battery.

l When working with the battery, always wear safety glasses and take care not to allow any battery fluids (acid) to come into contact with skin, cloth- ing or the vehicle body.

l Do not lean over the battery.

l In the event that battery fluid comes into contact with the skin or eyes, immediately wash the affected area with water and seek medical attention.

Place a wet sponge or cloth over the affected area until medical attention can be received.

l Always wash your hands after handling the battery support, terminals, and other battery-related parts.

l Do not allow children near the battery.


- When handling jumper cables
Be careful that the jumper cables do not become tangled in the cooling fan or any of the belts when connecting or disconnecting them.

If you see steam: Stop the engine. Carefully lift the hood after the steam subsides and then restart the engine.

If you do not see steam: Leave the engine running and carefully lift the hood.

is operating.Check to see if the cooling fan is operating.

If the fan is operating: Wait until the engine coolant temperature gauge begins to fall and then stop the engine.

If the fan is not operating: Stop the engine immediately and call your Lexus dealer.

After the engine has cooled

After the engine has cooled down sufficiently, check the engine coolant level and inspect the radiator core (radiator) for any leaks.

If the engine compartment cover needs to be removed:

Add engine coolant if neces-

Add engine coolant if neces- sary.

Water can be used in an emergency if engine coolant is unavailable.

Have the vehicle checked at the nearest Lexus dealer as soon as possible.

- Overheating
If you observe the following, your vehicle may be overheating.

l The engine coolant temperature gauge enters the red zone or a loss of power is experienced.

l Steam is coming from under the hood.


- To prevent an accident or injury when inspecting under the hood of your vehicle
l If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The engine compartment may be very hot, caus- ing serious injury such as burns.

l Keep hands and clothing away from the fan and other belts while the engine is running.

l Do not loosen the radiator cap or the coolant reservoir cap while the engine and radiator are hot.

Serious injury, such as burns, may result from hot coolant and steam released under pressure.


- When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.

When adding coolant, do so slowly. Adding cool coolant to a hot engine too quickly can cause damage to the engine.

Carry out the following procedures if the tires spin or the vehicle becomes stuck in mud, dirt, or snow.

- When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the sur- rounding area is clear, to avoid striking other vehicles, objects or people.

The vehicle may also lunge forward or lunge back suddenly as it becomes free. Use extreme caution.

- When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.

This may lead to unexpected rapid acceleration of the vehicle that may cause an accident resulting in death or serious injury.


- To avoid damaging the transmission and other components
l Avoid spinning the rear wheels and depressing the accelerator pedal more than necessary.

l If the vehicle remains stuck even after these procedures are performed, the vehicle may require towing to be freed.

Only in an emergency, such as if it becomes impossible to stop the vehicle in the normal way, stop the vehicle using the following proce- dure:

with both feet and firmlySteadily step on the brake pedal with both feet and firmly depress it.

Do not pump the brake pedal repeatedly as this will increase the effort required to slow the vehicle.

To stop the engine, press and hold the “ENGINE START STOP” switch for 3 consecu- tive seconds or more, or press it briefly 3 times or more in succession.


- If the engine has to be turned off while driving
Power assist for the brakes and steering wheel will be lost, making the brake pedal harder to depress and the steering wheel heavier to turn. Decelerate as much as possible before turning off the engine.
