Passlock
Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
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 is tampered with, fuel is disabled.
If the engine stalls and the SECURITY message flashes,
wait until the message stops flashing before trying to
restart the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the SECURITY message
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 ªFuses
and Circuit Breakersº in the Index). See your dealer
for service.
In an emergency, call the GMC Roadside Assistance
Center. See ªRoadside Assistanceº in the Index.
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º 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 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 ªTowing a Trailerº in the Index for
more information.

Accessory Power Outlets
With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
other devices designed to operate with vehicle
electrical systems.
Your vehicle is equipped with four accessory power
outlets. The front outlet is located next to the
Secondary Information Center (SIC) on the floor
console. Lift up on the door to access the outlet.
The second outlet is located in the center console.
Press the button on the side of the console door to
access the outlet. See ªCenter Console Storage Areaº
earlier in this section for more information.
There are also two accessory power outlets located on
the rear of the center console. Lift up on the doors to
access the outlets.
Certain electrical accessories may not be compatible
with the accessory power outlets and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.NOTICE:
Adding some electrical equipment to your vehicle
can damage it or keep other things from working
as they should. This wouldn't be covered by your
warranty. Check with your dealer before adding
electrical equipment, and never use anything that
exceeds the amperage rating.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
NOTICE:
Power outlets are designed for accessory plugs
only. Do not hang any type of accessory or
accessory bracket from the plug. Improper use
of the power outlet can cause damage not covered
by your warranty.

Underhood Fuse BlockThe underhood fuse block is located on the driver's side
of the vehicle near the battery. See ªEngine
Compartment Overviewº in the Index for more
information on its location. Lift the cover for access to
the fuse/relay block.
Once you remove the cover, you will see some fuses to
the top right of the fuse/relay block. These are spare
fuses and can be used accordingly.
You can remove fuses with a fuse extractor. The fuse
extractor is located in the underhood fuse block. To
remove fuses if you don't have a fuse extractor, hold the
end of the fuse between your thumb and index finger
and pull straight out.
