STARTING AND DRIVING
CAUTION
If the warning light comes on, observe the following
instructions:

appropriate speed that conditions permit.

braking. If the vehicle tires deteriorate, you could

causing death or serious injury.

If the warning light blinks and chimes sound every few
minutes, the tire pressure is very low.
Immediately stop your vehicle and check that the tire pressure
is as specified on the tire pressure label. The air pressure
gauge is located in the tool bag. Locate the deflated tire and
change to the spare tire. For the procedure for changing the
tire, see "If you have a flat tire (Vehicles with standard tires)"
on page 241.
The spare tire is not equipped with the tire pressure sensor.
So, the warning light remains on even if the spare tire is
mounted.
