3427-2. Steps to take in an emergency
■The tire pressure warning light may come on due to natural causes
The tire pressure warnin g light may come on due to natural causes such as natural air leaks
and tire inflation pressure chan ges 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 wa rning system may not function properly
P.304
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning lig ht frequently comes on after blinking for 1 minute when the
engine switch
checked by your Lexus dealer.
■Warning buzzer
In some cases, the buzzer may not be heard du e to being in a noisy location or audio sound.
■Customization
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features: P.391)
WARNING
■If both the ABS and the brake sy stem warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehicle
will become extremely unstable during brakin g, 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.
●Decelerate to the lowest appr opriate speed as soon as possible. Do not drive over 50
mph (80 km/h).
●Check and adjust the tire in flation pressure immediately.
●If the tire pressure warning lig ht comes on even after tire inflation pressure adjustment,
it is probable that you have a flat tire. Have the flat tire replaced by the nearest Lexus
dealer.
●Avoid abrupt maneuvering and braking. If th e 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.
