Check
Tire
Pressure System
The check tire pressure system can alert you to a large
change in the pressure of one tire. The system won’t
alert you before you drive that a tire is low or flat.
You must begin driving before the system will work
properly.
The
LOW
TIRE PRESSURE message will appear on
the Driver Information Center (DIC)
if
pressure difference
(low pressure) is detected in one tire. The check tire
pressure system may not alert you
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, 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 3-36.
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 5-60.
When the
LOW
TIRE PRESSURE message appears on
the Driver Information 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
5-70.
Also check the tire pressure in all four tires as soon as
you can. See
Inflation
--
Tire Pressure on page 5-60.
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.
