may not come on even if the tire pressure is low, or it
may come on when the tire pressure is actually normal:
•
more than one tire is low,
•
only one tire is replaced with a new tire during
service,
•
the vehicle is moving faster than 70 mph (113 km/h),
•
the system is not yet calibrated,
•
the tire treadwear is uneven,
•
the compact spare tire is installed,
•
tire chains are being used, or
•
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 3-39.
The check tire pressure system detects differences
in tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a low
tire – but it doesn’t replace normal tire maintenance.
See Tires on page 5-48.
When the LOW TIRE PRESSURE HOLD SET TO
RESET message appears on the Driver Information
Center and the LOW TIRE PRESSURE message comes
on the message center, 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 on page 5-58. Also check
the tire pressure in all four tires as soon as you can.
See Inflation -- Tire Pressure on page 5-49.
Any time you adjust a tire’s pressure or have one or more
tires repaired or replaced, you’ll need to reset (calibrate)
the check tire pressure system. You’ll also need to reset
the system whenever you rotate the tires, buy new tires
and install or remove the compact spare.
Don’t reset the check tire pressure system without first
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.
To reset the system:
1. Turn the ignition to ON with the engine off.
2. Press the MODE button until the DIC reads LOW
TIRE PRESSURE HOLD SET TO RESET.
3. Press and hold the SET button until you hear a
chime and TIRE PRESSURE RESET is displayed.
You will hear three chimes and the LOW TIRE
PRESSURE message will go off and the DIC will return
to TIRE PRESSURE NORMAL. If the LOW TIRE
PRESSURE message comes back on, the check tire
pressure system has not reset. Repeat the procedure.
