2006 BUICK TERRAZA air suspension

Level Control
With this feature, the rear of the vehicle is automatically
kept level as you load or unload your vehicle. However,
you should still not exceed the GVWR or the GAWR.
SeeLoading Your Vehicle on page 4-32.
You may hear the compressor operating when you load
or unload your vehicle, and periodically as the system
self-adjusts. This is normal. The compressor should
operate for brief periods of time. If the sound continues
for an extended period of time, your vehicle needs
service.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask your
dealer to help you load your vehicle the right way.
Towing a Trailer
{CAUTION:
If you do not use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well — or even
at all. You and your passengers could be
seriously injured. Pull a trailer only if you have
followed all the steps in this section. Ask your
dealer for advice and information about towing
a trailer with your vehicle.
Notice:Pulling a trailer improperly can damage
your vehicle and result in costly repairs that would
not be covered by your warranty. Always follow
the instructions in this section and check with your
dealer for more information about towing a trailer
with your vehicle.
Your vehicle can tow a trailer. To identify the trailering
capacity of your vehicle, you should read the information
in “Weight of the Trailer” that appears later in this section.

Tire Chains
{CAUTION:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension or
other vehicle parts. The area damaged by the
tire chains could cause you to lose control of
your vehicle and you or others may be injured
in a crash.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it is contacting your vehicle, and do
not spin your vehicle’s wheels. If you do nd
traction devices that will t, install them on the
front tires.
Accessory Inator
Your vehicle has an accessory inator. With it, you can
inate things like air mattresses and basketballs, and you
can also use it to bring your tires up to the proper
pressure.
The accessory inator is located in the rear
compartment on the driver’s side. To access the
accessory inator, do the following:
1. Open the liftgate. SeeLiftgate on page 2-24for
more information.
2. Lift the lever to move the third row rear seatback
forward. SeeThird Row Seat on page 1-11for
more information.
3. Remove the cover by pulling the lever out.
This symbol is on the
accessory inator switch.

Maintenance Footnotes
#Lubricate the suspension, steering linkage, transaxle
shift linkage, and the underbody contact points and
linkage.
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chang, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect other brake parts, including calipers,
parking brake, etc. Check parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts,
signs of wear or lack of lubrication. Inspect power
steering lines and hoses for proper hook-up, binding,
leaks, cracks, chang, etc.
(c)Visually inspect hoses and have them replaced if they
are cracked, swollen, or deteriorated. Inspect all pipes,
ttings and clamps; replace with genuine GM parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.(d)Visually inspect wiper blades for wear or cracking.
Replace wiper blades 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, hood latch
assemblies, secondary latches, pivots, spring anchor
and release pawl, hood and door hinges, rear folding
seats, liftgate hinges, fuel door hinge, power sliding door
cable, and sliding door track(s). 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)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.
