7-2. Steps to take in an emergency
■Conditions that the tire pressure warning system may not function properly
 P.330
■If the tire pressure warning light frequently 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 is turned to IGNITION ON mode , 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 reliabl e 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 st eering 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 ev en 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.
