Check Tire Pressure System - Buick 2006 Rendezvous Owner's Manual

Check Tire Pressure System

Your vehicle may have a check tire pressure system
that 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 HOLD SET TO RESET
message will appear on the Driver Information Center
(DIC) and the LOW TIRE PRESSURE message
will come on the message center if pressure difference,
or low pressure, is detected in one tire. In the following
conditions, the LOW TIRE PRESSURE message
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
•
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 3-45.
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 does not replace normal tire maintenance. See Tires
on page 5-51.
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 5-69. Also check
the tire pressure in all four tires as soon as you can.
See Inflation - Tire Pressure on page 5-57.
Any time you adjust a tire's pressure or have one or
more tires repaired or replaced, you'll need to reset, or
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.
Do not 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.
