Tire pressure warning system

The tire pressure warning system is de-
signed to provide warning when tire
pressure of any one of the tires is criti-
cally low while the vehicle is moving.
The low tire pressure warning light
comes on to inform you that such low
tire pressure may hamper driving.
This system is not designed to operate
when the vehicle is stopped. Therefore,
check the tire pressure regularly. The rec-
ommended cold tire pressure, tire size
and the vehicle capacity weight are on the
tire pressure label. (For instructions, see
"Checking tire inflation pressure" on page
463 in Section 7−2.)
Installed tires should be of the specified
size. They should be of the same size
and construction. If tires other than the
specified size are used, or if tires of dif-
ferent sizes or constructions are mixed,
the tire pressure warning system will not
function properly.
LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the "ON" position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.
If the low tire pressure warning light
comes on or blinks while driving, do
the following.
If the warning light comes on:
Vehicles with standard tires—
Adjust the tire pressure to the specified
level as soon as possible. (See "Tires"
on page 491 in Section 8.)
