

If the tire pressure warning light blinks for

approximately 1 minute then stays on

There may be a malfunction in the tire pres-

sure warning system. Have the vehicle

inspected by any authorized Lexus retailer

or Lexus authorized repairer, or any reli-

able repairer immediately.



If the tire pressure warning light comes

After the temperature of the tires has

lowered sufficiently, check the inflation

pressure of each tire and adjust them to

the specified level.

If the warning light does not turn off

even after several minutes have

elapsed, check that the inflation pres-

sure of each tire is at the specified level

and perform initialization. (



P.377)

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, adjust-

ing the tire inflation pressure will turn off the

warning light (after a few minutes).

When a tire is replaced with a spare tire

(vehicles with compact spare tire)

The compact spare tire is not equipped with

a tire pressure warning valve and transmit-

ter. If a tire goes flat, the tire pressure warn-

ing light will not turn off even though the flat

tire has been replaced with the spare tire.

Replace the spare tire with the repaired tire

and adjust the tire inflation pressure. The

tire pressure warning light will go off after a

few minutes.

ing system may not function properly

WARNING

If both the ABS and the brake system

warning lights remain on

Stop your vehicle in a safe place immedi-

ately 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 precau-

tions.

Failure to do so could cause a loss of

vehicle control and result in death or

serious injury.

Stop your vehicle in a safe place as

soon as possible. 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. Check the tires. If a tire is flat,

change it with the spare tire and have

the flat tire repaired by the nearest any

authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer.
