Downloaded from www.Manualslib.com manuals search engine 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 keyless entry transmitter:
1.
2.
3.

5.
Insert a dime in the slot between the covers of the
transmitter housing near the key ring hole. Remove
the bottom by twisting the dime.
Remove and replace the battery with a three volt
CR2032 or equivalent battery, positive
(+) side up.
Align the covers and snap them together.
Resynchronize the transmitter.
Check the operation of the transmitter.
Resynchronization
Resynchronization may be necessary due to the security
method used by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to
a signal it has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the
LOCK and UNLOCK
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle
to confirm
synchronization.
If the locks do not cycle, see your
dealer for service.

Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it.
When you park your vehicle and open the driver’s door, you’ll hear a chime reminding you to remove your key
from the ignition and take it with you. Always
do this.
Your steering wheel will be locked, and
so will your
ignition. If you have an automatic transmission, taking
your key out also locks your transmission. And
remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with
you.
If you park in a lot where someone will be watching
your vehicle, it’s best to lock it up and take your keys.
But what if
you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your
glove box.
0 Lock all the doors except the driver’s.
Passlock@
Your vehicle is equipped with the Passlock
theft-deterrent system.
Passlock is a passive theft-deterrent system. The system
is armed once the key is removed from the ignition.
Passlock enables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used, fuel
is disabled.
During normal operation, the
SECURITY light will go
off after the engine is started.

Downloaded from www.Manualslib.com manuals search engine If the engine stalls and the SECURITY light flashes,
wait about
10 minutes until the light stops flashing
before trying to restart the engine. Remember to release
the
key from the START position as soon as the
engine starts.
If the engine does not start after three (3) tries, the
vehicle needs service.
If you are driving 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 (see “Fuses and
Circuit Breakers” in the Index). See your dealer
for service.
If the
SECURITY light flashes, wait until the light stops
flashing before starting the engine.
If the
SECURITY light comes on while the engine is
running, a problem has been detected and the system
may need service. See your dealer for service.
In an emergency, call the
GM Roadside Assistance
Center. See “Roadside Assistance” in the Index.
New Vehicle “Break-In”
NOTICE:
Your vehicle doesn’t need an elaborate
“break-in.” But
it will perform better in the long
run if
you follow these guidelines:
a

Keep your speed at 55 mph (88 km/h) or
less for the
first 500 miles (805 km).
Don’t drive at any one speed
-- fast or
slow -- for the first 500 miles (805 km).
Don’t make full-throttle starts.
Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren’t 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.
Don’t tow
a trailer during break-in.
See “Towing a Trailer’’ in the Index for
more information.

Attach the upper
loops to the retainers on either side of
the endgate opening (the label should be in the upper
passenger side corner, visible from the rear
of vehicle).
Attach the lower hooks to the rear cargo tie downs on
the floor.
I Roll-Up Cargo Cover (If Equipped)
If you have the optional cargo cover, you can use it to
cover items in the cargo area of your vehicle.
Grasp the handle and unroll the cover. Latch the posts
into the sockets
on the inside trim panel on the
passenger’s side of the vehicle to secure it.
IOU may have a convenience net in the rear of your
vehicle
to help keep small items, like gloves and light
clothing in place during sharp turns or quick stops
and starts.
The net is not designed
to retain these items during
off-road use. The net
is not for larger, heavier items.
An improperly stored cargo cover could be
thrown about the vehicle during a collision or
sudden maneuver.
You or others could be
injured.
If you remove the cover, always store it
outside of the vehicle. When you put it back,
always be sure that it is securely reattached.

Downloaded from www.Manualslib.com manuals search engine Cargo Tie Downs
There are four cargo tie
downs in the rear that allow
you to strap cargo in and
keep it from moving inside
the vehicle.
Luggage Carrier (Option)
If you try to carry something on top of your
vehicle that
is longer or wider than the luggage
carrier
-- like paneling, plywood, a mattress, and
so forth -- the wind can catch it as you drive
along. This can cause you to lose control. What
you are carrying could be violently torn
off, and
this could cause you or other drivers to have a
collision, and of course damage your vehicle. You
may be able to carry something like this inside.
But, never carry something longer or wider than
the luggage carrier on top of your vehicle.
The luggage carrier has slats, side rails and crossrails
attached to the roof to secure cargo. The adjustable tie
downs, at either end
of the crossrails, should be used to
secure loads to the luggage carrier.
Use
GM accessory racks that are compatible with your
luggage carrier for transporting sports equipment. These
are available through your
GM dealer.

Downloaded from www.Manualslib.com manuals search engine rou can adjust the crossrails to handle loads of various
sizes. Just loosen
the slider knobs at each end of the
crossrail and
move them to where you want them. Make
sure both sides of the crossrails are even, then tighten
the slider knobs.
Be sure the cargo is properly loaded. Follow
these guidelines:
Carrying small, heavy loads on the roof is
not recommended.
Tie the load to the tie down (at either end of
the crossrails). When loading cargo directly on
the roof panel, use the crossrails to keep the load
from shifting.
If you need to carry long items, move the crossrails
as far apart as possible. Tie the load to the tie downs
provided.
Also tie the load to the bumpers. Do not tie
the load
so tightly that the crossrails or side rails
are damaged.
NOTICE:
Loading cargo that weighs more than 200 lbs.
(91 kg) on the luggage carrier may damage your
vehicle. When you carry large things, never let
them hang over the rear or the sides of your
vehicle. When loading cargo on the roof panel, be
sure it rests on the slats and does not scratch
or
damage the vehicle.
Put the cargo against the side rails and fasten it
securely to the luggage carrier. Put the main
weight
as far forward as you can and move the
rear crossrail forward as far as possible to keep
the load from shifting.
Don’t exceed the maximum vehicle capacity when loading your vehicle. For more information
on vehicle
capacity and loading, see “Loading
Your Vehicle” in
the Index.
To prevent damage or
loss of cargo as you’re driving,
check now and then to make sure the luggage carrier and
cargo are still securely fastened.
