Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
1. Use a at thin object to pry open the transmitter.
2. Once the transmitter is separated, use a pencil
or similar object to remove the old battery.
Do not use a metal object.3. Insert the new battery as the instructions under the
cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Press any button on the remote keyless entry
transmitter to resynchronize the transmitter.
6. Check the operation of the transmitter.

DIC Vehicle Personalization
If your vehicle has the Navigation system, see the
Navigation system manual for instructions on operating
the DIC for your vehicle.
Your vehicle has personalization that allows you to
program certain features to a preferred setting for up to
two people. The number of programmable features
varies depending upon which model of the vehicle is
purchased.
On all vehicles, features such as climate control
settings, radio preset settings, exterior lighting at unlock,
remote lock and unlock conrmation, and automatic
door locks have already been programmed for
your convenience.
Some vehicles have additional features that can be
programmed including the seat and outside rearview
mirror position.
If your vehicle has the ability to program additional
personalization features, the driver’s preferences are
recalled by pressing the unlock button on the Remote
Keyless Entry (RKE) transmitter, 1 or 2, or by pressing
the appropriate memory button, 1 or 2, located on
the driver’s door. Certain features can be programmed
not to recall until the key is placed in the ignition.
To change feature preferences, see “Entering the
Personalization Menu” following.
Entering the Personalization Menu
To enter the feature programming mode, use the
following procedure:
1. Turn the ignition to ON, but do not start the engine.
Make sure an automatic transmission is in PARK (P)
or a manual transmission has the parking brake set.
To avoid excessive drain on the battery, it is
recommended that the headlamps are turned off.
2. If your vehicle has memory settings, press the
appropriate memory button, 1 or 2, located on
the driver’s door armrest. The DIC display will show
either Driver 1 or 2 depending on which button
was selected.
3. Press the PWR/VOL knob to turn the radio on.
4. Press the TUNE/SEL knob once to access the main
menu of the DIC.
5. Turn the TUNE/SEL knob until SETUP is highlighted.
6. Press the TUNE/SEL knob once to access the
SETUP menu.
7. Turn the TUNE/SEL knob until the feature you want
to change is highlighted, then press the TUNE/SEL
knob to turn the feature on or off. If the feature
is turned on, a check mark will appear next to the
feature name.
If none of the personalization items are turned on,
turn on the personalization menu by pressing
the TUNE/SEL knob. The list of features will then
appear, and you can repeat Step 6.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality GM brake parts.
When you replace parts of your braking system — for
example, when your brake linings wear down and you
need new ones put in — be sure you get new approved
GM replacement parts. If you do not, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change — for the
worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
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 5-12for 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.
{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 5-42for tips on working around a battery
without getting hurt.
After a power loss, such as disconnecting the battery
or removing the maxi fuses in the power distribution
fuse block, the following steps must be performed
to calibrate the electronic throttle control. If this is not
done, the engine will not run properly.
1. Turn the ignition key to ON. Do not start the engine.
2. Leave the ignition in ON for at least three minutes
so that the electronic throttle control will cycle and
re-learn its home position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least
30 seconds.
