Q

Front passenger detection sensor, seat belt reminder and warning buzzer

O

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.

O

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

light may not operate properly.

Q

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.

Q

electric power steering system warning light may come on and the warning buzzer may 

sound.

Q

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 is blinking, 

turn the engine switch <power switch> from off to IGNITION ON mode <ON mode> and 

check if the warning light blinks.

Q

When the tire pressure warning light comes on

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

O

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

O

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. (

Q

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).

Q

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 <power switch> is turned to IGNITION ON mode <ON mode>, have it 

checked by any authorized Lexus retailer or Lexus authorized repairer, or any reliable 

repairer.

Q

Warning buzzer

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

WARNING

Q

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.

Q

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.

Q

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.

O

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

km/h (50 mph).

O

Check and adjust the tire inflation pressure immediately.

O

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.

O

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

control of the steering wheel or the brakes.

Q

If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.
