How to Check

Use a good quality pocket-type gage to check tire

pressure. You cannot tell if your tires are properly

inﬂated simply by looking at them. Radial tires may look

properly inﬂated even when they’re underinﬂated.

Check the tire’s inﬂation pressure when the tires are cold.

Cold means your vehicle has been sitting for at least

three hours or driven no more than 1 mile (1.6 km).

Remove the valve cap from the tire valve stem.

Press the tire gage ﬁrmly onto the valve to get a

pressure measurement. If the cold tire inﬂation pressure

matches the recommended pressure on the tire and

loading information label, no further adjustment is

necessary. If the pressure is low, add air until you

reach the recommended amount.

If you overﬁll the tire, release air by pushing on the

metal stem in the center of the tire valve. Recheck the

tire pressure with the tire gage.

Be sure to put the valve caps back on the valve stems.

They help prevent leaks by keeping out dirt and moisture.

Tire Pressure Monitor Operation

This vehicle may have a Tire Pressure Monitor System

(TPMS). The TPMS is designed to warn the driver

when a low tire pressure condition exists. TPMS sensors

are mounted onto each tire and wheel assembly.

The TPMS sensors monitor the air pressure in the

vehicle’s tires and transmit the tire pressure readings

to a receiver located in the vehicle.

When a low tire pressure

condition is detected, the

TPMS will illuminate

the low tire pressure

warning symbol located

on the instrument

panel cluster.

At the same time a message to check the pressure in a

speciﬁc tire appears on the Driver Information Center

(DIC) display. The low tire pressure warning light

and the DIC warning message come on at each ignition

cycle until the tires are inﬂated to the correct inﬂation

pressure. Using the DIC, tire pressure levels can

be viewed by the driver. For additional information and

details about the DIC operation and displays see DIC

Warnings and Messages on page 3-12. Also, see “DIC

Operation and Displays” in the Index of the owner

manual for more information.
