when the “ENGINE START STOP” switch is turned to IGNITION ON mode, have
it checked by Lexus dealer.

Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury. ●
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately. ●

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. ●

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.
