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 inflation 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. Re-check 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.
Check Tire Pressure System
The Check Tire Pressure System is designed to alert
the driver when there is a large change in the air
pressure of one tire. The system learns the air pressure
at each tire throughout the operating speed range of
the vehicle, and compares tire rotational speeds using
the Anti-lock Brake System’s wheel speed sensors.
The Check Tire Pressure System will not alert you
before you drive the vehicle that a tire is low or flat. You
must begin driving the vehicle before the system will
work properly.
The CHECK TIRE PRESSURE warning message, on
the Driver Information Center (DIC), and the tire
pressure warning light, on the instrument panel cluster,
will come on if the system detects a pressure
difference in one of the four tires installed on the
vehicle. For additional information and details about the
DIC operation and displays see
Displays on page 3-50
. An example of the tire pressure
warning light is shown under
page 3-44
.
The Check Tire Pressure System may not warn you of
a tire pressure condition if:
•
More than one tire is low.
•
The vehicle is moving faster than
65 mph (105 km/h).
•
The system is not yet calibrated.
•
The tire treadwear is uneven.
•
The compact spare tire is installed.
•
Tire chains are being used.
•
The vehicle is being driven on a rough or
frozen road.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-41
