To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the on/off button until a Z and a
zone number appears in the display. The compass
is now in zone mode.3. Keep pressing the on/off button until the desired
zone number appears in the display. Release the
button. After approximately four seconds of
inactivity, the new zone number will be locked in
and the compass/temperature display will return.
4. Calibrate the compass as described next.
Compass Calibration
The compass may need calibration if one of the
following occurs:
After approximately ve seconds, the display does
not show a compass heading, N for North, for
example, there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic antenna mount, magnetic
note pad holder, or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
push the on/off button for approximately 12 seconds
or until CAL is displayed.
The compass can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads a direction.

Compass Operation
Press the COMP button once briey to turn the compass
on or off.
When the ignition is started and the compass feature is
on, the compass will show two character boxes for
approximately two seconds. After two seconds,
the mirror will display the compass heading.
Compass Calibration
The compass may need calibration if one of the
following occurs:
If CAL is displayed while driving in the vehicle.
After approximately ve seconds, the display does
not show a compass heading, N for North, for
example, there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic antenna mount, magnetic
note pad holder, or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, push
in the COMP button for approximately eight seconds
or until CAL is displayed.
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display
reads a direction.
Compass Variance
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if the vehicle is outside zone eight.
Under certain circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. Compass variance is the difference
between earth’s magnetic north and true geographic
north. If not adjusted to account for compass variance,
your compass could give false readings.

Manual Folding
The mirrors can be manually folded inward to prevent
damage when going through an automatic car wash.
To fold, push the mirror toward the vehicle. To return the
mirror to its original position, push outward. Be sure
to return both mirrors to their original unfolded position
before driving.
Heated Mirrors
The button to turn the heated mirrors on or off is located
on the climate control panel. Press this button to warm
the driver’s and passenger’s outside rearview mirrors to
help clear them of ice, snow, and condensation.
See “Rear Window Defogger” underDual Automatic
Climate Control System on page 3-24for more
information.
Convex Mirror
The passenger’s side mirror may have convex glass.
A convex mirror’s surface is curved so more can
be seen from the driver’s seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
2-55

Park Tilt Mirrors
If your vehicle has the memory package, the outside
mirrors are able to perform the park tilt function. This
feature may be useful in allowing the driver to view the
curb when parallel parking. This feature will cause the
passenger’s and/or driver’s mirror to tilt to a preselected
position when the vehicle is in REVERSE (R).
The passenger’s and/or driver’s mirror will return to
its original position when the vehicle is shifted out
of REVERSE (R), or the ignition is turned off or to
OFF/LOCK.
This feature can be turned on or off through the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 3-66.

The display is located
above the rear window and
can be seen by looking
over your right shoulder.
URPA uses three color-coded lights to provide distance
and system information.
How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). The rear display briey
illuminates to indicate the system is working.
URPA operates only at speeds less than 5 mph
(8 km/h). If the vehicle is above this speed, the red
light on the rear display will ash.To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below tailgate level.
Objects must also be within 8 feet (2.5 m) from the
rear bumper. This distance may be less during warmer
or humid weather.
A single beep will sound the rst time an object is
detected between 20 inches (0.5 m) and 8 feet (2.5 m)
away. Beeping will occur for a short time when the
vehicle is closer than 1 foot (0.3 m) from the object.
The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:
Description English Metric
amber light 8 ft 2.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights 23 in 0.6 m
amber/amber/red lights

Windshield Washer
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
L(Washer Fluid):Push the paddle marked with the
windshield washer symbol at the top of the multifunction
lever, to spray washer uid on the windshield. The
wipers clear the window and then either stop or return
to the preset speed.
Heated Windshield Washer
For vehicles with the heated windshield washer uid
system it can be used to help clear ice, snow, tree sap,
or bugs from your windshield.The button is located in
the switchbank under the
climate controls.
Push the heated washer uid button to activate the
heated windshield washer uid system. The indicator
light will ash. This activation initiates four heated
wash/wipe cycles. The rst heated wash/wipe cycle may
take up to 40 seconds to occur, depending on outside
temperature. After the rst wash/wipe cycle, it may take
up to 20 seconds for each of the remaining cycles to
begin. Press the button again to turn off the heated
windshield washer uid system or it will automatically
turn off after four wipe cycles have been completed.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer nozzles
for a short period of time before washer uid is sprayed.
This is a normal condition.

Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up
or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as Battery Saver Active or
Service Battery Charging System. If this message is
displayed, it is recommended that the driver reduce the
electrical loads as much as possible. SeeDIC Warnings
and Messages on page 3-59.
Battery Run-Down Protection
This feature shuts off the dome lamps if they are left on
for more than 10 minutes when the ignition is in LOCK.
This will help prevent the battery from running down.

Climate Controls
Climate Control System
The heating, cooling, defrost, defog and ventilation of
your vehicle can be controlled with this system.
Manual Operation
Turn the right knob clockwise or counterclockwise to
direct the airow inside of the vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets and to the oor outlets. The
ow can be divided between vent and oor outlets
depending upon where the knob is placed between the
settings. A little air is directed towards the windshield
and side window outlets. Cooler air is directed to
the upper outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets, with some of the air directed to the
windshield, side window outlets, and second row oor
outlets. In this mode, the system will automatically select
outside air. Recirculation cannot be selected when in
Floor Mode.
The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging
and Defrosting” later in this section.
By positioning the right knob between two modes,
a combination of those two modes is selected.
The air conditioning compressor will be on unless the
outside temperature is close to freezing.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the knob all the way counterclockwise to turn the
front system off.
:(Outside Air):Press this button to turn on the
outside air mode. When this mode is selected, air from
outside the vehicle will circulate throughout your vehicle.
An indicator light on the button comes on to show that it
is activated. The outside air mode can be used with
all modes, but it cannot be used with the recirculation
mode. Pressing this button again will cancel the
recirculation mode.
3-21

?(Recirculation):Press this button to turn on the
recirculation mode. When the button is pressed, an
indicator light will come on.
This mode keeps outside air from entering the vehicle. It
can be used to reduce outside air and prevent odors from
entering the vehicle. Recirculation may also help cool the
air inside your vehicle more quickly once the temperature
inside the vehicle is less than the outside temperature.
The recirculation mode cannot be used with oor, defrost,
or defogging modes. If you try to select recirculation in
one of those modes, the indicator light will ash three
times and turn off. The air conditioning compressor will
also come on when this mode is activated. While in
recirculation mode the windows may fog when the
weather is cold and damp. To clear the fog, select either
the defog or defrost mode and increase the fan speed.
Recirculation mode can be turned off by pressing the
button again, or turning off the engine.Temperature Control:Rotate the thumbwheels up or
down to increase or decrease the temperature on the
driver’s side or the passenger side of the vehicle for the
dual zone system, if equipped. Otherwise, turn the center
knob clockwise or counterclockwise to increase or
decrease the temperature inside the vehicle.
#(Air Conditioning):Press this button on the left
knob to turn the air conditioning system on or off. When
A/C is pressed, an indicator light comes on to show
that the air conditioning has been activated.
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.
The air conditioning system removes moisture from the
air, so a small amount of water might drip underneath
the vehicle while idling or after turning off the engine.
This is normal.
3-22

Defogging and Defrosting
Fog on the inside of the windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to clear
fog or frost from your windshield. Turn the right knob
clockwise to select the defog or defrost mode.
-(Defog):The defog mode is used to clear the
windows of fog or moisture and warm the passengers.
This mode directs air to the windshield, oor outlets,
and side window vents. When this mode is selected,
the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is close to freezing. The recirculation mode cannot be
selected while in the defog mode. Do not drive the
vehicle until all the windows are clear.
0(Defrost):The defrost mode is used to remove
fog or frost from the windshield more quickly. This mode
directs a portion of the air to the windshield and side
window vents and some to the oor vents. In this mode,
the system will automatically force outside air into the
vehicle. The recirculation mode cannot be selected while
in the defrost mode. The air conditioning compressor
will run automatically in this setting, unless the outside
temperature is close to freezing. Do not drive the vehicle
until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):Press this button on
the right knob to turn on the rear window defogger.
The system will automatically turn off several minutes
after it has been activated. The defogger can also
be turned off by pressing the button again or by turning
off the engine. Do not drive the vehicle until all the
windows are clear.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would
not be covered by the vehicle warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
