If the tire pressure warning light comes on

Be sure to observe the following precautions. Failure to do so could cause loss of

vehicle control and result in death or serious injury.

●

Vehicles with standard tires:

°

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

adjustment, 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.

●

Vehicles with run-flat tires:

°

Decelerate to the lowest appropriate speed as soon as possible. Do not drive

over 55 mph (90 km/h).

°

Check and adjust the tire inflation pressure immediately.

° If the tire pressure warning light comes on even after tire inflation pressure

adjustment, it is probable that you have a flat tire. Have the tire replaced 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

The tire pressure warning system may not activate immediately.
