2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 11

NOTE: The Driver and Front Passenger Advanced Front
Air Bags are certified to the new Federal regulations for
Advanced Air Bags. The Advanced Front Air Bags have a multistage inflator
design. This allows the air bag to have different rates of
inflation based on several factors, including the severity
and type of collision.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is fastened. The
seat belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.
NOTE:
• Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.Advanced Front Air Bag And Knee Bolster Locations 1 — Driver And Passenger

• After any accident, the vehicle should be taken to an
authorized dealer immediately.
Air Bag System Components
Your vehicle may be equipped with the following air bag
system components:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolster
• Driver Advanced Front Air Bag
• Passenger Advanced Front Air Bag
• Front Seat Belt Pretensioners, Seat Belt Buckle Switch,
and Seat Track Position Sensors Advanced Front Air Bag Features
The Advanced Front Air Bag system has multistage
driver and front passenger (if equipped) air bags. This
system provides output appropriate to the severity and
type of collision as determined by the Occupant Restraint
Controller (ORC).
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.
WARNING!• No objects should be placed over or near the air
bag on the instrument panel, because any such
objects could cause harm if the vehicle is in a
collision severe enough to cause the air bag to
inflate.

Air Bag Deployment Sensors And Controls
Occupant Restraint Controller (ORC)
The ORC is part of a Federally regulated safety system
required for this vehicle.
The ORC determines if deployment of the front air bags
in a frontal or side collision is required. Based on the
impact sensor’s signals, a central electronic ORC deploys
the Advanced Front Air Bags, and front seat belt preten-
sioners — if equipped, as required, depending on several
factors, including the severity and type of impact.
Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal collisions depending on several factors,
including the severity and type of collision. Advanced
Front Air Bags are not expected to reduce the risk of
injury in rear, side or rollover collisions. The Advanced Front Air Bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions. On
the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.
Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 57

to the left of the button will illuminate to indicate when
the dimming feature is activated. The sensor to the right
of the button does not illuminate.
NOTE: This feature is disabled when the vehicle is
moving in reverse. CAUTION!To avoid damage to the mirror during cleaning, never
spray any cleaning solution directly onto the mirror.
Apply the solution onto a clean cloth and wipe the
mirror clean.
Outside Mirrors
To receive maximum benefit, adjust the outside mirror(s)
to center on the adjacent lane of traffic with a slight
overlap of the view obtained on the inside mirror.

Compass / Temperature Display
The compass readings indicate the direction the vehicle is
facing. The EVIC will display one of eight compass
readings and the outside temperature.
NOTE:
• The system will display the last known outside tem-
perature when starting the vehicle and may need to be
driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect
the displayed temperature; therefore, temperature
readings are not updated when the vehicle is not
moving.
• During snowplow usage on vehicles equipped with
outside temperature display, the display may show
higher temperatures than the outside ambient tem-
perature. The higher displayed temperature is due to
blocked or reduced airflow to the underhood ambient temperature sensor caused by the snowplow. In addi-
tion, on vehicles equipped with Automatic Tempera-
ture Control (ATC), it is suggested that the interior
cabin temperature be manually controlled should the
system not perform as desired while in automatic
mode. Both the outside temperature display and ATC
operation will return to normal when the snowplow is
removed.
Automatic Compass Calibration
This compass is self-calibrating, which eliminates the
need to manually reset the compass. When the vehicle is
new, the compass may appear erratic and the EVIC will
display CAL until the compass is calibrated. You may
also calibrate the compass by completing one or more
360–degree turns (in an area free from large metal or
metallic objects) until the CAL indicator displayed in the
EVIC turns off. The compass will now function normally.214 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE: Keep magnetic materials away from the top of
the instrument panel, such as iPod’s, Mobile Phones,
Laptops and Radar Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings.
1. Turn the ignition switch ON. 2. Press the UP or DOWN button until the System Setup
(Customer-Programmable Features) menu is reached,
then press the SELECT button.
3. Press the DOWN button until the “Compass Variance”
message is displayed in the EVIC, then press the SELECT
button. The last variance zone number displays in the
EVIC.
4. Press and release the SELECT button until the proper
variance zone is selected, according to the map.
5. Press and release the BACK button to exit.
Customer-Programmable Features (System
Setup)
Personal Settings allows you to set and recall features
when the transmission is in PARK. If the transmission is
out of PARK or the vehicle begins moving, a warning
message SYSTEM SETUP NOT AVAILABLE, is fol-
lowed in three seconds by, VEHICLE NOT IN PARK.Compass Variance Map216 UNDERSTANDING YOUR INSTRUMENT PANEL

CLIMATE CONTROLS
The Climate Control System allows you to regulate the
temperature, amount, and direction of air circulating
throughout the vehicle. The controls are located on the
instrument panel below the radio.
NOTE: During snowplow usage on vehicles equipped
with outside temperature display, the display may show
higher temperatures than the outside ambient tempera-
ture. The higher displayed temperature is due to blocked
or reduced airflow to the underhood ambient tempera-
ture sensor caused by the snowplow. In addition, on
vehicles equipped with Automatic Temperature Control
(ATC), it is suggested that the interior cabin temperature
be manually controlled should the system not perform as
desired while in automatic mode. Both the outside tem-
perature display and ATC operation will return to nor-
mal when the snowplow is removed. Manual Heating And Air Conditioning System
The controls for the manual heating and air conditioning
system in this vehicle consist of a series of outer rotary
dials and inner push knobs. These comfort controls can
be set to obtain desired interior conditions.

General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer’s instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion. When plowing snow, to avoid transmission and drive-
train damage, the following precautions should be ob-
served.
• Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
• Vehicles with automatic transmissions should use 4L
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
• Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.364 STARTING AND OPERATING
