Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about two years.
the battery is weak if the transmitter does not work
at the normal range in any location. If you have
to get close to your vehicle before the transmitter
works, it is probably time to change the battery.
The Driver Information Center (DIC) will display a
KEY FOB # BATTERY LOW message when
the transmitter battery is low.
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 in the RKE transmitter do
the following:
1. Insert a thin coin in the slot between the
covers of the transmitter housing. Gently
pry the transmitter apart.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

To avoid setting off the alarm by accident, do the
following:
Always lock the vehicle using the door key
afterthe doors are closed.
Always unlock a door with a key, or use the
RKE transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any
door with the key. You can also turn off the alarm
by pressing unlock on the RKE transmitter.
The alarm will not stop if you try to unlock a door
any other way.
Testing the Alarm
To test the alarm, do the following:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the power door lock switch while the door is
open, or with the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.When the alarm is set the power door unlock
switch will not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 493.
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by
your dealer.
Passlock®
Your vehicle has the Passlock®theft-deterrent
system.
Passlock
®is a passive theft-deterrent system that
enables fuel if the ignition lock cylinder is turned
with a valid key. If a correct key is not used or the
ignition lock cylinder has been tampered with, the
fuel system is disabled and the vehicle will not start.
During normal operation, the security light will
turn off about ve seconds after the key is turned
to RUN.
111

If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.
If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light
comes on, you will be able to restart the engine if
you turn the engine off. However, your
Passlock
®system is not working properly and
must be serviced by your dealer. Your vehicle is
not protected by Passlock
®at this time. You
may also want to check the fuse. SeeFuses and
Circuit Breakers on page 493. See your dealer
for service.
In an emergency, call the GM Roadside
Assistance Center. SeeRoadside Assistance
Program on page 532.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Keep your speed at 55 mph (88 km/h)
or less for the rst 500 miles (805 km).
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake, or slow, the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 362for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.
112

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components.
If the ignition key is turned to the START
position, and then released when the engine
begins cranking, the engine continues cranking
for a few seconds or until the vehicle starts.
If the engine does not start and the key is held
in START for many seconds, cranking stops
after 15 seconds to prevent cranking motor
damage. To prevent gear damage, this system
also prevents cranking if the engine is
already running. Engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator.
If the vehicle starts briey but then stops
again, do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently until the oil
warms up and lubricates all moving parts.
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. Any resulting damage would
not be covered by your vehicle’s warranty.

Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like
other vehicles) look farther away than
they really are. If you cut too sharply into
the right or left lane, you could hit a
vehicle. Check your inside mirror or
glance over your shoulder before
changing lanes.
The passenger’s outside mirror is convex.
A convex mirror’s surface is curved so more
can be seen from the driver’s seat.
Outside Heated Mirrors
Your vehicle may have this feature. When you
operate the rear window defogger, the defogger
also warms the heated driver’s and passenger’s
outside rearview mirrors to help clear them of ice,
snow and condensation.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and
two downward (for left) positions. These positions
let you signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is nished, the lever
returns automatically.
An arrow on the
instrument panel cluster
ashes in the direction
of the turn or lane
change.
To signal a lane change, raise or lower the lever
until the arrow starts to ash. Hold it there until you
complete your lane change. The lever returns
by itself when released. The bottom of the outside
rearview mirrors might also have lane change
indicators.As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb could be burned out and other drivers will not
see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
you signal a turn, check the fuse. SeeFuses and
Circuit Breakers on page 493and check for
burned-out bulbs.
If you have a trailer towing option with added
wiring for the trailer lamps, a turn signal asher is
used. With this asher installed, the signal
indicator ashes even if a turn signal bulb is
burned out. Check the front and rear turn signal
lamps regularly to make sure they are working.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime sounds at each ash of
the turn signal. To turn off the chime, move
the turn signal lever to the off position.
