Air Vents
Use the louvers located on the air
vents to change the direction of the
airflow.
To open or close off the airflow:
.On the center air vents, move
the slider knobs up or down.
. On the outer and rear air vents,
move the slider knobs right
or left.
Operation Tips
. Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
. Clear snow off the hood to
improve visibility and help
decrease moisture drawn into
the vehicle, which may improve
long term system performance. .
Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
. Do not attach any devices to the
air vent slats. This restricts
airflow and may cause damage
to the air vents.
Maintenance
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
See Maintenance Schedule 0368.
To find out what type of filter to use,
see Maintenance Replacement
Parts 0378.

2. Disconnect the glove box doordamper (1) from the glove box
door assembly by squeezing
the pivot (2) to release the
damper ring.3. Squeeze both sides of theglove box bin inward to lower
beyond the stops.
4. Remove the two screwssecuring the door.
5. Press the latches on either side of the service door inward to
release. Open the service door
and remove the old filter.
6. Install the new air filter.
7. Close the service door completely.
8. Reverse the steps to reinstall the glove box.
See your dealer if additional
assistance is needed.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.

During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.
The air conditioning system requires
periodic maintenance. See
Maintenance Schedule0368.

Driving Environment
Be prepared for driving in inclement
weather, at night, or during other
times where visibility or traction may
be limited, such as on curves,
slippery roads, or hilly terrain.
Unfamiliar surroundings can also
have hidden hazards.
Learn more about driving in different
conditions and off-road driving in
this section.
Vehicle Design
Utility vehicles have a significantly
higher rollover rate than other types
of vehicles. This is because they
have a higher ground clearance and
a narrower track or shorter
wheelbase than passenger cars,
which makes them more capable for
off-road driving. While these design
characteristics provide the driver
with a better view of the road, these
vehicles do have a higher center of
gravity than other types of vehicles.
A utility vehicle does not handle thesame as a vehicle with a lower
center of gravity, like a car, in similar
situations.
Safe driver behavior and
understanding of the environment
can help avoid a rollover crash in
any type of vehicle, including utility
vehicles.
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible:
.
Set the climate controls to the
desired temperature after the
engine is started, or turn them
off when not required.
. Avoid fast starts and accelerate
smoothly.
. Brake gradually and avoid
abrupt stops.
. Avoid idling the engine for long
periods of time. .
When road and weather
conditions are appropriate, use
cruise control.
. Always follow posted speed
limits or drive more slowly when
conditions require.
. Keep vehicle tires properly
inflated.
. Combine several trips into a
single trip.
. Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
. Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local
governments have enacted laws

Continue to follow the instructions in
the DIC messages. Hold the
exhaust brake switch on the center
stack below the climate controls for
more than three seconds, and then
release it, to begin the regeneration
process.
If the EXHAUST BRAKE ON
message displays, then the switch
was released too soon. Press it
again to turn off the exhaust brake,
then try again when the DIC
message prompts.
When manual regeneration begins,
the engine speed increases, the
engine cooling fan sound increases,
and a DIC message indicates that
cleaning is in progress.A DIC message will display when
cleaning is complete. Cleaning
could take up to 30 minutes. Upon
completion, the engine will return to
normal idle, but exhaust
components will remain hot for
several minutes. Do not move the
vehicle until the exhaust has had
time to cool. Manual regeneration
can be canceled at any time by
pressing the brake pedal or by
turning the engine off. Unusual
noises may be heard if regeneration
is interrupted.Diesel Exhaust Fluid
{Warning
Avoid getting Diesel Exhaust
Fluid (DEF) on your skin or in
your eyes as it could cause
irritation. For more safety,
handling, and storage information,
see the Diesel Exhaust Fluid
container label.
Diesel Exhaust Fluid (DEF) is used
with diesel engines to reduce the
amount of regulated emissions
produced. Products such as AdBlue
are types of DEF, and are approved
for use in the vehicle as long as
they have an API certification label
or meet ISO 22241.The fluid level in
the DEF tank must be maintained
for the vehicle to run properly. DEF
is not a fuel additive. DEF should
not be mixed with or added to diesel
fuel. DEF freezes when exposed to
temperatures below −11 °C (12 ° F).
