Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 364for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm. Wash
hands after handling.
Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (−) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 394for tips on working
around a battery without getting hurt.
Also, for your audio system, seeTheft-Deterrent
Feature on page 296.

Windshield Replacement
Keep in mind that your windshield is part of the
Head-Up Display (HUD) system. If you ever have
to get your windshield replaced, be sure to get
one that is designed for HUD or your HUD image
may look blurred or out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear and cracking. SeeScheduled Maintenance
on page 475for more information.
Replacement blades come in different types and
are removed in different ways. For proper type and
length, seeNormal Maintenance Replacement
Parts on page 486.

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,
seeAnti-Lock Brake System Warning Light on
page 220.
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. SeeTires on page 406.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 at, seeIf a Tire Goes Flat on
page 427. Also check the tire pressure in all four
tires as soon as you can. SeeIn ation - Tire
Pressure on page 413.
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
rst 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.
415

To reset the system, do the following:
1. With the engine off, turn the ignition to ON.
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, then 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.
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 30 and 60 minutes of driving to learn
the tire pressures. The system normally takes
10 to 20 minutes of driving in each speed range
to learn tire pressures. The speed ranges are
20 to 40 mph (32 to 64 km/h), 40 to 60 mph
(64 to 96 km/h), and above 60 mph (96 km/h).
This time may be longer depending on yourindividual driving habits. The learning process
does not need to be completed during a single trip.
Once learned, the system will remember the tire
pressure until the system is reset.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. SeeWhen
It Is Time for New Tires on page 418andWheel
Replacement on page 422for more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire, If it
moves, use the folding wrench to tighten the cable.
SeeStoring a Flat or Spare Tire and Tools on
page 444.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 475.

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.
