elapsed, check that the inflation pres-
sure of each tire is at the specified level
and perform initialization. (  P.388)
■

system may fail, which could cause an
accident resulting in death or serious

heavier than usual, grip the steering
wheel firmly and operate it using more
force than usual. ■

comes on
Be sure to observe the following precau-
tions.
Failure to do so could cause a loss of
vehicle control and result in death or
serious injury.

Decelerate to the lowest appropriate
speed as soon as possible. Do not
drive over 50 mph (80 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 prob able that you have
a flat tire. Have the flat tire replaced by
