Climate Controls
Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with these systems.
A. Fan Control
B. Temperature Control
C. Air Delivery Mode Control
9(Off):Turns the system off.
Temperature Control:Turn clockwise or
counterclockwise to increase or decrease the
temperature.
9(Fan):Turn clockwise or counterclockwise to
increase or decrease the fan speed. To turn the fan off,
turn the air delivery control counterclockwise to the off
position.Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the direction of the airflow
inside the vehicle.
To change the current mode, select one of the following:
H(Vent):Air is directed to the instrument panel vents.
)(Bi-Level):Air is divided between the instrument
panel and floor vents. Cooler air is directed to the upper
vents and warmer air to the floor vents.
6(Floor):Air is directed to the floor vents. Use this
mode to send air to the rear of the vehicle. Keep
the area under the front seats free of objects that could
obstruct airflow to the rear of the vehicle.
-(Defog):This mode clears the windows of fog or
moisture. Outside air is directed to the floor and
defroster outlets. Adjust the temperature knob for
warmer or cooler air. The air conditioning compressor
may operate in this setting to dehumidify the air.
0(Defrost):This mode removes fog or frost from the
windshield more quickly. Air is directed to the windshield,
with some going to the floor outlets and front side
windows. The air conditioning compressor may operate in
this setting to dehumidify the air.
The temperature knob should be in the red area and the
fan control toward high. Do not drive the vehicle until all
the windows are clear. Vehicles Without Air Conditioning

Defogger
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
Air Delivery Mode Control:Turn clockwise or
counterclockwise to change the direction of the airflow
inside the vehicle.
Select from the following modes:
<(Maximum Air Conditioning):For maximum
cooling. The system goes into recirculation mode and
helps to maximize the air conditioner’s performance and
the vehicle’s fuel economy. This setting also cools the air
the fastest.
Y(Air Conditioning):For normal cooling on hot days.
Outside air is cooled and directed to the instrument
panel vents.
)(Bi-Level Air Conditioning):Air is divided between
the floor and instrument panel vents. The air conditioning
compressor cycles continuously in this setting as long as
the outside temperature is warm enough to activate the
compressor.
H(Vent):Air is directed to the instrument panel vents.
6(Floor):Air is directed to the floor vents. Use this
mode to send air to the rear of the vehicle. Keep the area
under the front seats free of objects that could obstruct
airflow to the rear of the vehicle.
-(Defog):This mode clears the windows of fog or
moisture. Outside air is directed to the floor and
defroster outlets. Adjust the temperature knob for
warmer or cooler air. The air conditioning compressor
may operate in this setting to dehumidify the air.

the windows are clear. Vehicles With Air Conditioning

Audio System(s)
If the vehicle came without a radio, the wiring provisions
for a radio and an antenna were installed at the
assembly plant, so that if you want, a radio can be
installed at the dealer/retailer.
Determine which radio the vehicle has and read the
following pages to become familiar with its features.
{CAUTION:
Taking your eyes off the road for extended periods
could cause a crash resulting in injury or death to
you or others. Do not give extended attention to
entertainment tasks while driving.
This system provides access to many audio and non
audio listings.
To minimize taking your eyes off the road while driving,
do the following while the vehicle is parked:
•Become familiar with the operation and controls of
the audio system.
•Set up the tone, speaker adjustments, and preset
radio stations.
For more information, seeDefensive Driving on
page 4-2.Notice:Contact your dealer/retailer before adding
any equipment.
Adding audio or communication equipment could
interfere with the operation of the vehicle’s engine,
radio, or other systems, and could damage them.
Follow federal rules covering mobile radio and
telephone equipment.
Notice:The chime signals related to safety belts,
parking brake, and other functions of your vehicle
operate through the radio/entertainment system.
If that equipment is replaced or additional equipment
is added to your vehicle, the chimes may not
work. Make sure that replacement or additional
equipment is compatible with your vehicle before
installing it. SeeAccessories and Modifications
on page 5-3.
Setting the Clock
Press and hold the HR (down) or MIN (up) arrow for
two seconds. Then press HR until the correct hour
displays. Press and hold MIN until the correct minute
displays. The time can be set with the ignition on or off.

Radio(s)
Your vehicle has one of these radios as its audio system.
Playing the Radio
PWR (Power):Press to turn the system on and off.
VOL (Volume):Turn clockwise or counterclockwise to
increase or to decrease the volume.
RCL (Recall):Press to switch the display between the
radio station frequency and the time. When the ignition is
off, press to display the time.
Finding a Station
AM FM:Press to switch between FM1, FM2, and AM.
The selection displays.
TUNE:Turn to select radio stations.
oSEEKp:Press the arrows to go to the previous or
to the next station.
To scan stations, press and hold either arrow for
two seconds until a beep sounds. The radio goes to
a station, plays for a few seconds, then goes to the next
station. Press either arrow again to stop scanning.
To scan preset stations, press and hold either arrow for
more than four seconds until two beeps sound. The radio
goes to the first preset station stored on the pushbuttons,
plays for a few seconds, then goes to the next preset
station. Press either arrow again to stop scanning
presets.
The radio only seeks and scans stations, with a strong
signal, that are in the selected band. Radio with CD shown, AM-FM Radio similar

4. Install the new filter element.
5. Reinstall and tighten the filter container and
reconnect the water sensor wire to the filter.
6. Use the fuel filter priming procedure earlier in this
section to prime the fuel filter.
7. Tighten the air bleed valve by turning it clockwise
until hand-tight.
8. Start the engine and let it idle for five minutes.
Check the fuel filter and air bleed valve for leaks.
How to Reset Fuel Filter Change
Light - DURAMAX 6.6L (LMM) Engine
The engine controller calculates when to change the fuel
filter based on vehicle and fuel use. Whenever the
fuel filter is changed, reset the fuel filter light so
the engine controller can calculate when the next fuel
filter change is required. If the fuel filter is ever changed
prior to a change fuel filter light being turned on,
reset the fuel filter change light.To reset the Fuel Filter Change light:
1. Turn the ignition key to ON/RUN with the engine off
2. Fully press the accelerator and brake pedals at the
same time for 10 seconds. If the Fuel Filter Change
light flashes for 5 seconds, the system is resetting.
3. Turn the key to OFF.
If the Fuel Filter Change light comes back on when you
start the vehicle, the light has not been reset. Repeat
the procedure. SeeChange Fuel Filter Warning Light on
page 3-45for more information.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel might be hard
to find. Never use leaded gasoline or any other fuel
not recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel would not
be covered by the vehicle warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you will be driving.
