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.

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.

192 Driving and Operating
Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
SeeShifting Into Park 0187 and
Engine Exhaust 0191.
If parking on a hill and pulling a
trailer, see Driving Characteristics
and Towing Tips 0262.
Diesel Particulate
Filter
The exhaust system has a Diesel
Particulate Filter (DPF) to reduce
vehicle emissions. On some
exhaust systems with a DPF, the
exhaust cooler mixes air with the
exhaust to lower the temperature
before it leaves the tailpipe.
The DPF, the tailpipe, and other
exhaust system components must
not be altered. Inspect regularly and
clean any mud or dirt from the
exhaust cooler, especially where the
exhaust cooler connects to the
tailpipe and the openings where
fresh air enters the cooler.
The DPF will clean itself as part of
normal operation. Several factors
including fuel consumed, hours of
engine operation, and miles driven
are monitored by the Engine Control
Module (ECM). The self-cleaning
occurs approximately once per tank
of fuel. Vehicles with the DPF have specific
fuel and engine oil requirements.
See
Fuel for Diesel Engines 0250
and
Engine Oil 0283.
Caution
Damage can occur to the DPF
components if the required Ultra
Low Sulfur Diesel (15 ppm sulfur
maximum) fuel and either CJ-4 or
CK-4 engine oil are not used.
This damage would not be
covered by the vehicle warranty.
Under certain conditions, such as
idling or very short trips, the
self-cleaning process has less
efficiency and cannot be completed.
To resolve this, continue driving
safely at a steady speed as close to
the posted speed limit as possible,
preferably without stopping, until the
message turns off. This can take up
to 30 minutes.

Driving and Operating 193
{Warning
During DPF self-cleaning or
during extended idling in P (Park),
the exhaust system and exhaust
gases are very hot. Things that
burn could touch hot exhaust
parts under the vehicle and ignite.
You or others could be burned.
Do not park, or idle for an
extended period of time, near or
over papers, leaves, dry grass,
or other things that can burn.
Keep the exhaust area clear of
material that could ignite or burn.
SeeParking over Things That
Burn 0190.
Caution
Avoid extended idling because
the DPF system is not capable of
self-cleaning at idle. During
extended idling, monitor the
instrument cluster lights and DIC
(Continued)
Caution (Continued)
for messages and take
appropriate action. Continued
idling with the warning light/
message on could cause damage
to the DPF requiring repair and
possible replacement that might
not be covered by the vehicle
warranty.
During self-cleaning there will be a
change in the exhaust sound and
engine idle speed. Along with this, a
burning smell and reduction in fuel
economy may be noticed. This is
normal.
If the vehicle is idled or driven on
very short trips with the DPF
warning message on and the
exhaust filter is not cleaned as
required, the malfunction indicator
lamp and a DIC message will
display. See your dealer. Also see
Malfunction Indicator Lamp (Check
Engine Light) 0115. If equipped with Power
Take-Off (PTO), monitor the
instrument cluster for lights related
to the DPF.
See
Accessories and Modifications
0 275 if you are adding accessories
or modifying the vehicle.
Manual Regeneration of Diesel
Particulate Filter
This feature is only available on
Fleet and Commercial vehicles.
To verify that the vehicle has this
feature, refer to the Vehicle Service
Parts Identification label (SPID) for
RPO code FPF or see
www.gmupfitter.com to contact the
GM Upfitter Integration Group.
If equipped, this feature allows for
manual cleaning/regeneration of the
DPF when it is unable to clean
itself. It may be necessary to
perform manual regeneration if
driving conditions —such as
extended slow speed, stop-and-go
traffic, extended idling, short drive
cycles, or stationary PTO operation
— prevent DPF self-cleaning.

3. Turn the drain plug counterclockwise using a
suitable tool.
4. With the engine off, press and hold ENGINE START/STOP
without applying the brake for
five seconds to place the
vehicle in Service Mode. See
Ignition Positions 0179. Wait
approximately five seconds,
and then press ENGINE
START/STOP again to turn it
off. This operation will enhance
water flow out of the filter. The filter is drained as soon as
diesel fuel emerges from
the port.
5. Retighten the drain plug by turning it clockwise.
6. Properly dispose of the water contaminated fuel.
7. Start the engine and let it run for a few minutes. During the
draining process, air may have
entered the fuel system. If the
engine stalls, the fuel system
may need to be primed. See
“Fuel Priming” following.
Fuel Priming
For the fuel system to work properly,
air cannot be in the fuel lines. If air
gets in, the engine may not start
and the fuel lines will need to be
primed before operating the vehicle.
If air is present, the following may
have happened:
. The vehicle ran out of fuel.
. The fuel filter was removed.
. The fuel lines were removed or
disconnected. .
The fuel filter water drain valve
was opened while the engine
was running.
To prime the fuel lines: 1. With the engine off, press and hold ENGINE START/STOP
without applying the brake for
five seconds to place the
vehicle in Service Mode. See
Ignition Positions 0179. Wait
approximately five seconds
and press ENGINE START/
STOP again to turn it off. Do
this step three times or more
while the engine is off.
2. Press and hold ENGINE START/STOP while applying
the brake for a maximum of
40 seconds at a time, with
five seconds between attempts,
until the engine starts. If the
engine tries to run, but does
not run smoothly, increase the
rpm’s slightly by using the
accelerator pedal. This will help
force air through the system.
3. Repeat Step 2 if the engine stalls and will not restart.
