Electric power steering system warning light (warning buzzer)
When the 12-volt 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 is blinking,
turn the engine switch <power switch> from off to IGNITION ON mode <ON mode> and
check if the warning light blinks.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire pres-
sure warning reset switch will not turn off the tire pressure warning light.
■
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).
■
Conditions that the tire pressure warning system may not function properly

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

engine switch <power switch> is turned to IGNITION ON mode <ON mode>, have it
checked by your Lexus dealer.

WARNING
■
If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. 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 in 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.
