Section 2 Features and Controls
2-1

There is one double-sided
key for the ignition, driver’s
door lock, and tailgate.
When a new vehicle is delivered, the dealer provides
the owner with a pair of identical keys and a key
code number.
The key code number tells your dealer or a qualied
locksmith how to make extra keys. Keep this number in
a safe place. If you lose your keys, you will be able
to have new ones made easily using this number. Your
dealer should also have this number.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you ever do get locked out of your vehicle call the
GM Roadside Assistance Center. SeeRoadside
Assistance Program on page 7-5.If your vehicle is equipped with the OnStar system with
an active subscription and you lock your keys inside
the vehicle, OnStar may be able to send a command to
unlock your vehicle. SeeOnStar

the handle located on the front edge of the rear
door panel to open it. You must close the rear door
before closing the front door.

while pulling the tailgate down.
When you put the tailgate back up, be sure it latches
securely.
You can lock the tailgate using your ignition key.

cables from both sides of
the tailgate by pulling
the clips away from the bolt
heads while pushing the
cable bracket forward.
When the larger part of
the hole on the bracket is
over the bolt, slide the
bracket off of the bolt.
2. With the tailgate partially down, lift up on the
passenger’s side and pull the tailgate toward
you, then move the tailgate to the right to release
the driver’s side. You can then remove the
entire tailgate assembly.

the hole on the bracket
is over the bolt, slide
the bracket off of
the bolt.
3. Slide the lower end tting onto the top bolt.
The tailgate will now stay in the partially opened
position.
4. Repeat steps 2 and 3 for the driver side.

(d)Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(e)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors, and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular maintenance.
(f)Lubricate all key lock cylinders, body door and
fuel door hinges, latches and locks (including glove box
and console doors), hood latch assembly, secondary
latch, pivots, spring anchor, release pawl, and any
moving seat hardware. Lubricate hood safety lever
pivot and prop rod pivot and tailgate latch bolt, handle
assembly pivot points, and hinges. More frequent
lubrication may be required when exposed to a corrosive
environment. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal
better, and not stick or squeak.
(g)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the uid level checked. Add uid if needed.(h)Change automatic transmission uid and lter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i)Drain, ush, and rell cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-25 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap, and ller neck. Pressure test the
cooling system and pressure cap.
(j)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.
(k)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
