Low Tire Pressure Light (If Equipped)

The tire pressure

monitor system can

alert you to a large

change in the

pressure in one tire.

After the system has “learned” tire pressures with

properly inflated tires, the LOW TIRE PRESSURE light

will come on if the pressure in one tire becomes 12 psi

(83 kPa) lower than the other three tires. The tire

pressure monitor system won’t alert you if the pressure

in more than one tire is low, if the system is not yet

calibrated, or if the vehicle is moving at less than

15 mph (25 km/h), faster than 75 mph (120 km/h), on

rough roads or during turns. The light may also come on

if you are driving on partially cleared pavement.

When the LOW TIRE PRESSURE light comes on, you

should stop as soon as you can and check all your tires

for damage. (If a tire is flat, see “If a Tire Goes Flat” in

the Index.) Also check the tire pressure in all four tires

as soon as you can. See “Inflation

- Tire Pressure” in

the Index.

The light will stay on (while the ignition is on) until you

reset (calibrate) the system. See “Tire Pressure Monitor

System” in the Index.

The LOW TIRE PRESSURE light also comes on briefly

when you turn the ignition key to ON. If the light

doesn’t come on then, have it fixed so it will be there to

tell you if the pressure in a tire is low or high.

If the anti

-lock brake system warning light comes on,

the tire pressure monitor system may not be working.

See your dealer for service. Also, see “Anti-Lock Brake

System Warning Light” in the Index.
