warning BUICK LUCERNE 2006 Repair Manual

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. 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 at. 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 seeDIC Controls and
Displays on page 3-50. An example of the tire pressure
warning light is shown underTire Pressure Light on
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.
5-63

The system can alert you about a low tire — but it does
not replace normal tire maintenance. SeeTires on
page 5-56.
When the tire pressure warning light and the CHECK
TIRE PRESSURE message comes on, you should stop
as soon as you can and check all your tires for
damage. If a tire is at, seeIf a Tire Goes Flat on
page 5-72. Also check the tire pressure in all four tires
as soon as you can. SeeInation - Tire Pressure
on page 5-62.
Any time you adjust a tire’s pressure or have one or
more tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will
also need to reset the system whenever you rotate the
tires, buy new tires, and install or remove the compact
spare tire.
Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires to the
recommended amount. SeeInation - Tire Pressure on
page 5-62. 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 (calibrate) the system:
1. Turn the ignition switch to RUN, with the engine off.
2. Press the vehicle information button on the DIC
until the PRESS
VTO RESET TIRE SYSTEM
message appears on the display.
3. Press and hold the DIC Set/Reset button for about
ve seconds. After ve seconds, the display will
show TIRE PRESSURE SYSTEM RESET. If the
TIRE PRESSURE SYSTEM RESET message does
not appear in the display after about ve seconds,
repeat the procedure starting with Step 2. If it does
not work after two tries, see your dealer for service.
The system completes the calibration process during
driving. The system learns the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 20 and 45 minutes of
driving in each of the following speed ranges to learn tire
pressures: 25 to 40 mph (40 to 64 km/h), 40 to 60 mph
(64 to 96 km/h), and 60 to 85 mph (96 to 136 km/h). This
time may be longer depending on your individual driving
habits. Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is reset.

Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the norm
due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specied government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance.
Warning:The traction grade assigned to this tire is
based on straight-ahead braking traction tests, and does
not include acceleration, cornering, hydroplaning, or
peak traction characteristics.
Temperature – A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specied indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning:The temperature grade for this tire is
established for a tire that is properly inated and not
overloaded. Excessive speed, underination, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your vehicle’s tires properly.
If air goes out of a tire, it is much more likely to leak out
slowly. But if you should ever have a blowout, here
are a few tips about what to expect and what to do:
If a front tire fails, the at tire will create a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you would
use in a skid. In any rear blowout remove your foot from
the accelerator pedal. Get the vehicle under control
by steering the way you want the vehicle to go. It may
be very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.
If a tire goes at, the next part shows how to use the
jacking equipment to change a at tire safely.
Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your vehicle’s
hazard warning ashers. SeeHazard Warning Flashers
on page 3-6for more information.
