CAUTION
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 profes-
sional. 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
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.

Be sure to observe the following precautions. Failure to do so could cause a
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 infla-
tion pressure immediately.
If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires. If a
tire is flat, change it with the spare tire and have the flat tire repaired by
the nearest any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.
