1-7. Safety information
CAUTION
■SRS airbag precautions
Observe the following precautions regarding the airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver airbag is th e first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a
clear margin of safety. This distance is measured from the center of the steering
wheel to your breastbone. If you sit less than 10 in. (250 mm) away now, you can
change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many dr ivers can achieve the 10 in. (250 mm)
distance, even with the driver seat all the way forward, simply by reclining the
back of the seat somewhat. If reclining the back of your seat makes it hard to
see the road, raise yourself by using a firm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

5-2. Steps to take in an emergency
CAUTION
■When the electric power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, firmly hold and
operate it using more force than usual.
■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.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat ti re. 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
The tire pressure warning system may not activate immediately.
