■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The comp act spare tire is not equipped with a tire pressure warning valve and transmitter. If a ti re goes flat, the tire pressure warning light
will not turn off even though th e 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 pressurewarning light will go off after a few minutes.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure warning valve and transmitter. The tire pressure warning light will turn on if the tire infla- tion pressure of the spare tire is low. If a ti re goes flat, the tire pressure warning 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.
■Conditions that the tire pressure warning system may not function properly
P. 618
■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 dealer
or repairer, or another duly qualified and equipped professional. The vehicle will become extremely unstable during braking, and the ABS system may fail, which couldcause 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.
