How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inated simply by looking at them. Radial tires may
look properly inated even when they’re underinated.
Check the tire’s ination 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 rmly onto the valve to get a pressure
measurement. If the cold tire ination pressure matches
the recommended pressure on the Tire and Loading
Information label, no further adjustment is necessary.
If the ination pressure is low, add air until you reach
the recommended amount.
If you overll 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 System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
If your vehicle has this feature, sensors are mounted on
each tire and wheel assembly, except the spare tire.
The TPMS sensors monitor the air pressure in your
vehicle’s tires and transmit tire pressure readings to a
receiver located in the vehicle.
The TPMS is designed to alert the driver, if a low tire
pressure condition exists. This system also allows
the driver to check tire pressure levels using the Driver
Information Center (DIC).
When a low tire pressure condition is detected, the TPMS
displays the CHECK TIRE PRESSURE warning message
on the DIC, and at the same time illuminates the low tire
pressure warning symbol. For additional information
and details about the DIC operation and displays see
DIC Operation and Displays on page 3-53andDIC
Warnings and Messages on page 3-56.
You may notice, during cooler weather conditions, that
the tire pressure monitor light, located on the instrument
panel cluster, and the CHECK TIRE PRESSURE
message will appear when the vehicle is rst started and
then turn off as you start to drive the vehicle. This could
be an early indicator that the tire pressures are getting
low and need to be inated to the proper pressure.
