Environmental Concerns
Off-road driving can provide
wholesome and satisfying
recreation. However, it also raises
environmental concerns. We
recognize these concerns and urge
every off-roader to follow these
basic rules for protecting the
environment:
Always use established trails,
roads, and areas that have
been specially set aside for public
off-road recreational driving
and obey all posted regulations.
Avoid any driving practice that
could damage shrubs, owers,
trees, or grasses or disturb
wildlife. This includes
wheel-spinning, breaking down
trees, or unnecessary driving
through streams or over
soft ground.
Always carry a litter bag and
make sure all refuse is removed
from any campsite before
leaving.
Take extreme care with open
res (where permitted), camp
stoves, and lanterns.
Never park your vehicle over dry
grass or other combustible
materials that could catch re
from the heat of the vehicle’s
exhaust system.
Traveling to Remote Areas
It makes sense to plan your
trip, especially when going to a
remote area. Know the terrain and
plan your route. Get accurate
maps of trails and terrain. Check to
see if there are any blocked or
closed roads.
It is also a good idea to travel
with at least one other vehicle in
case something happens to one
of them.
For vehicles with a winch, be sure
to read the winch instructions.
In a remote area, a winch can be
handy if you get stuck but you
will want to know how to use
it properly.

Service
For service and parts needs, visit
your dealer/retailer. You will receive
genuine GM parts and GM-trained
and supported service people.
Genuine GM parts have one
of these marks:
Accessories and
Modications
When non-dealer/non-retailer
accessories are added to the
vehicle, they can affect vehicle
performance and safety, including
such things as airbags, braking,
stability, ride and handling,
emissions systems, aerodynamics,
durability, and electronic systems
like antilock brakes, traction control,
and stability control. Some of
these accessories could even cause
malfunction or damage not
covered by the vehicle warranty.
Damage to vehicle components
resulting from the installation or use
of non-GM certied parts, including
control module modications,
are not covered under the terms of
the vehicle warranty and may
affect remaining warranty coverage
for affected parts.

GM Accessories are designed to
complement and function with other
systems on the vehicle. Your GM
dealer/retailer can accessorize the
vehicle using genuine GM
Accessories. When you go to your
GM dealer/retailer and ask for GM
Accessories, you will know that
GM-trained and supported service
technicians will perform the work

Most motor vehicles, including this
one, contain and/or emit chemicals
known to the State of California
to cause cancer and birth defects
or other reproductive harm.Engine exhaust, many parts and
systems (including some inside the
vehicle), many uids, and some
component wear by-products
contain and/or emit these chemicals.
California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained
in remote keyless transmitters, may
contain perchlorate materials.
Special handling may be necessary.

Doing Your Own
Service Work
{CAUTION
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
Be sure you have sufficient
knowledge, experience, the
proper replacement parts, and
tools before attempting any
vehicle maintenance task.
Be sure to use the proper
nuts, bolts, and other
fasteners. English and metric
fasteners can be easily
confused. If the wrong
fasteners are used, parts can
later break or fall off. You
could be hurt.

Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on
page 5-10for the location of the
engine oil dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If you do not
do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it
with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the
tip down, and check the level.

Electrical System
Add-On Electrical
Equipment
Notice:Do not add anything
electrical to the vehicle unless you
check with your dealer/retailer
rst. Some electrical equipment
can damage the vehicle and the
damage would not be covered by
the vehicle’s warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle’s battery, even if the vehicle
is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing Your Airbag-Equipped
Vehicle on page 1-58.
Windshield Wiper Fuses
The windshield wiper motor is
protected by a circuit breaker and a
fuse. If the motor overheats due
to heavy snow or ice, the wiper will
stop until the motor cools. If the
overload is caused by some
electrical problem, have it xed.
Power Windows and
Other Power Options
Circuit breakers protect the
power windows and other power
accessories. When the current load
is too heavy, the circuit breaker
opens and closes, protecting the
circuit until the problem is xed
or goes away.
Power and Heated Seat
Circuit Breakers
There is a circuit breaker located
underneath the driver’s side
front seat that controls the power
and heated seat functions.
Fuses and Circuit
Breakers
The wiring circuits in your vehicle
are protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of res caused by electrical
problems.
Look at the silver-colored band
inside the fuse. If the band is
broken or melted, replace the fuse.
Be sure you replace a bad fuse
with a new one of the identical size
and rating.
If you ever have a problem on the
road and do not have a spare
fuse, you can borrow one that has
the same amperage. Just pick some
feature of your vehicle that you
can get along without — like the
radio or cigarette lighter — and use
its fuse, if it is the correct amperage.
Replace it as soon as you can.
