Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your
vehicle. If a transmitter is lost or stolen, a
replacement can be purchased through your
GM dealer. Remember to bring any additional
transmitters so they can also be re-coded to match
the new transmitter. Once your dealer has
coded the new transmitter, the lost transmitter will
not unlock your vehicle. The vehicle can have
a maximum of eight transmitters matched to it. See
“Relearn Remote Key” underDIC Operation and
Displays (With DIC Buttons) on page 244or
DIC Operation and Displays (Without DIC Buttons)
on page 251for instructions on how to match
RKE transmitters to your vehicle.

If a door is opened without using the RKE
transmitter, a ten second pre-alarm will occur.
The horn will chirp and the lights will ash. If the
key is not placed in the ignition and turned to
START or the door is not unlocked by pressing the
unlock button on the RKE transmitter during the
ten second pre-alarm, the alarm will go off.
Your vehicle’s headlamps will ash and the horn
will sound for about two minutes, then will turn
off to save the battery power.
The theft-deterrent system will not activate if you
lock the doors with a key, the manual door lock, or
the power door lock switch. It activates only if you
use the RKE transmitter. You should also
remember that you can start your vehicle with the
correct ignition key if the alarm has been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the
theft-deterrent system, the vehicle should be
locked with the door key after the doors
are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if the system has been armed.If you set off the alarm by accident, turn off the
alarm by pressing unlock on the RKE transmitter or
by placing the key in the ignition and turning it
to START.
Testing the Alarm
The alarm can be tested by following these steps:
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 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.
If the alarm does not sound when it should, but
the vehicle’s 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 540.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer for
service.

Driving Uphill
Once you decide you can safely drive up the hill,
you need to take some special steps.
Use a low gear and get a rm grip on the
steering wheel.
Get a smooth start up the hill and try to
maintain your speed. Do not use more power
than you need, because you do not want
your wheels to start spinning or sliding.
Try to drive straight up the hill if at all possible.
If the path twists and turns, you might want to
nd another route.
{CAUTION:
Turning or driving across steep hills can
be dangerous. You could lose traction,
slide sideways, and possibly roll over.
You could be seriously injured or killed.
When driving up hills, always try to go
straight up.
Ease up on your speed as you approach the
top of the hill.
Attach a ag to the vehicle to make you more
visible to approaching traffic on trails or hills.
Sound the horn as you approach the top of the
hill to let opposing traffic know you are there.
Use your headlamps even during the
day. They make you more visible to oncoming
traffic.
{CAUTION:
Driving to the top (crest) of a hill at full
speed can cause an accident. There could
be a drop-off, embankment, cliff, or even
another vehicle. You could be seriously
injured or killed. As you near the top of a
hill, slow down and stay alert.
