7-2. Steps to take in an emergency

High coolant temperature warning light (warning buzzer)

: This light illuminates on the multi-information display.

Front passenger detection sensor, seat belt reminder and warning buzzer

If luggage is placed on a front passenger seat, the front passenger detection sensor may

cause the warning light to flash and the warning buzzer to sound even if a passenger is not

sitting in the seat.

If a cushion is placed on the seat, the sensor may not detect a passenger, and the warning

light may not operate properly.

If the malfunction indicator lamp comes on while driving

The malfunction indicator lamp will come on if the fuel tank becomes completely empty. If

the fuel tank is empty, refuel the vehicle immediately. The malfunction indicator lamp will go

off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Lexus retailer or

Lexus authorized repairer, or any reliable repairer as soon as possible.

Electric power steering system warning light (warning buzzer)

When the battery charge becomes insufficient or the voltage temporarily drops, the electric

power steering system warning light may come on and the warning buzzer may sound.

Tire pressure warning light

When a malfunction occurs in the tire pressure warning system, the tire pressure warning

light blinks to warn the driver. However, if the warning light blinks for 1 minute, and then

remains illuminated, making it difficult to determine whether the warning light was blinking

initially, turn the engine switch from off to ON and check if the warning light blinks.

When the tire pressure warning light comes on

Carry out the following procedure after the tire temperature has lowered sufficiently.

Check the tire inflation pressure and adjust to the appropriate level.

If the warning light does not go out even after several minutes, check that the tire inflation

pressure is at the specified level and carry out initialization. (



P.357)

The warning light may come on again if the above operations are conducted without first

allowing the tire temperature to lower sufficiently.

The tire pressure warning light may come on due to natural causes

The tire pressure warning light may come on due to natural causes such as natural air leaks

and tire inflation pressure changes caused by temperature. In this case, adjusting the tire

inflation pressure will turn off the warning light (after a few minutes).

If the tire pressure warning light frequently comes on after blinking for 1 minute

If the tire pressure warning light frequently comes on after blinking for 1 minute when the

engine switch is turned to ON, have it checked by any authorized Lexus retailer or Lexus

authorized repairer, or any reliable repairer.

Warning buzzer

In some cases, the buzzer may not be heard due to being in a noisy location or audio sound.

WARNING

If both the ABS and the brake system warning lights remain on

Stop your vehicle in a safe place immediately and contact any authorized Lexus retailer

or Lexus authorized repairer, or any reliable repairer. The vehicle will become extremely

unstable during braking, and the ABS system may fail, which could cause an accident

resulting in death or serious injury.

When the electric power steering system warning light comes on

When the light comes on yellow, the assist to the power steering is restricted. When the

light comes on red, the assist to the power steering is lost and handling operations of the

steering wheel become extremely heavy. When steering wheel operations are heavier

than usual, grip the steering wheel firmly and operate it using more force than usual.

If the tire pressure warning light comes on

Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-

cle control and result in death or serious injury.

Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 80

km/h (50 mph).

Check and adjust the tire inflation pressure immediately.

If the tire pressure warning light comes on even after tire inflation pressure adjustment,

it is probable that you have a flat tire. Have the flat tire replaced by nearest authorized

Lexus retailer or Lexus authorized repairer, or any reliable repairer.

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose

control of the steering wheel or the brakes.

If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.

NOTICE

To ensure the tire pressure warning system operates properly

Do not install tires with different specifications or makers, as the tire pressure warning

system may not operate properly.
