Tire pressure warning system

The tire pressure warning system is de-
signed to provide warning when tire
inflation pressure of any one of the
tires is critically low while the vehicle
is moving. The low tire pressure warn-
ing 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 inflation pressure regularly.
The recommended cold tire inflation pres-
sure, tire size and the vehicle capacity
weight are on the tire and loading informa-
tion label. (For instructions, see "Checking
tire inflation pressure" on page 471 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.
