7-2. Steps to take in an emergency
When a tire is replaced with a spare tire (vehicles with the tire pressure warning sys-
■
tem)
The spare tire is also equipped with the tire pressure warning valve and transmitter. The
tire pressure warning light will turn on if the tire inflation pressure of the spare tire is low. If
a tire goes flat, even though the flat tire is replaced with the spare tire, the tire pressure
warning light does not turn off. Replace the spare tire with the repaired tire and adjust the
proper tire inflation pressure. The tire pressure warning light will turn off after a few min-
utes.

Warning buzzer
■
In some cases, the buzzer may not be heard due to being in a noisy location or audio
sound.
Speed warning buzzer (for India)
■
The buzzer sounds when your vehicle speed reaches or exceeds 80km/h (50 mph).
Then, the buzzer sounds when your vehicle speed reaches or exceeds 120 km/h (75 mph)
in a different tone.
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 vehi-
cle will become extremely unstable during braking, and the ABS system may fail, which
could cause an accident resulting in death or serious injury.
If the tire pressure warning light comes on (vehicles with the tire pressure warning
■
system)
Be sure to observe the following precautions. Failure to do so could cause loss of vehi-
cle control and result in death or serious injury.
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure
●
immediately.
If the tire pressure warning light comes on even after tire inflation pressure adjust-
●
ment, it is probable that you have a flat tire. Check the tires. If the tire is flat, change to
the spare tire and have the flat tire repaired by the nearest Lexus dealer.
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 (vehicles with the tire pressure warn-
■
ing system)
The tire pressure warning system may not activate immediately.
