Battery Replacement
The battery in your remote keyless entry transmitter
should last about three years.
If the battery is weak the transmitter will not work within
its normal range. It is probably time to change the
battery if you have to be very close to the vehicle before
the transmitter works.
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.To replace the battery do the following:
1. Insert a at object like a thin coin into the slot on
the back of the transmitter and pry apart the front
and back.
2. Remove the old battery, but do not use a metal
object to do this. Make sure the new battery is a
type CR2032 or equivalent, and that the positive (+)
side of the battery is facing down.
3. Snap the front and back of the transmitter together.
4. Resynchronize and test the operation of the
transmitter with the vehicle.
Resynchronization
After the battery has been changed in the remote
keyless transmitter, it will need to be resynchronized. To
do this, press and hold both the LOCK and UNLOCK
buttons until you hear one horn chirp.

The vehicle was originally programmed to Mode 3. The
mode may have been changed since then. To
determine the current mode, or to change the mode, do
the following:
1. Turn the ignition key to RUN.
2. Close all of the doors.
3. Apply the brakes.
4. Press and hold the power door lock switch in the
lock position.
5. Move the shift lever out of and back into PARK (P)

After initially moving the shift lever out of and back into
PARK (P), each additional shift cycle will advance
the programming from the current mode to the next
operating mode. If cycled beyond Mode 4, the vehicle
will enter operating Mode 1.
Disconnecting the vehicle’s battery for up to a year will
not affect the programmed mode.Lockout Protection
This feature helps to prevent a driver from locking the
keys inside of the vehicle by disabling the power
door locks when the following occurs:
A door is opened.
The key is left in the ignition.
A power door lock is pressed.
The lockout protection feature can be overridden by
holding the power door lock switch in the lock position
for more than three seconds while the key is in the
ignition and any door is open.
This feature cannot guarantee that you will never be
locked out of the vehicle. If the manual door lock is used
or if the key is left in the vehicle, but not in the ignition,
you could still be locked out of the vehicle. Always
remember to take the keys with you.
Leaving Your Vehicle
Before leaving the vehicle, take the keys, open the
door, and set the locks from inside. Then get out and
close the door. See “Delayed Locking” in this section for
more information.

Starting Your Engine
Move the shift lever to PARK (P) or NEUTRAL (N). The
engine will not start in any other position. That is a
safety feature. To restart the vehicle when it is already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as the
engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about 15
seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it does not start within 10 seconds, hold the key in
START for about 10 seconds at a time until the
engine starts. Wait about 15 seconds between each
try.3. If the engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing the accelerator pedal all the way to the
oor and holding it there as the key is held in
START for about three seconds. If the vehicle starts
briey but then stops again, do the same thing.
This time keep the pedal down for ve or six
seconds to clear the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.

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 new vehicle comes with a maintenance free
ACDelco®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
®
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.If your battery has a very low charge or is dead, you
may not be able to remove the ignition key from
the ignition switch or shift out of PARK (P). Refer to
Shifting Out of Park (P) on page 2-27.
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 5-47for tips on working around a battery
without getting hurt.
Contact your dealer to learn how to prepare your
vehicle for longer storage periods.
