Compass
Your vehicle may have a compass
in the Driver Information Center
(DIC). See Driver Information
Center (DIC) (Without DIC Buttons)
on page 5‑30 orDriver Information
Center (DIC) (With DIC Buttons) on
page 5‑25 for more information
about the DIC.
Compass Zone
The zone is set to zone eight upon
leaving the factory. Your dealer will
set the correct zone for your
location.
Under certain circumstances,
such as during a long distance
cross-country trip or moving to a
new state or province, it will be
necessary to compensate for
compass variance by resetting the
zone through the DIC if the zone is
not set correctly. Compass variance is the difference
between the earth's magnetic
north and true geographic north.
If the compass is not set to the zone
where you live, the compass may
give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
To adjust for compass variance,
use the following procedure:
Compass Variance (Zone)
Procedure
1. Do not set the compass zone

Lighting 6-7
Delayed Exit Lighting
Delayed exit lighting illuminates the
interior for a period of time after the
key is removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the key
is removed, interior illumination
activates and remains on until one
of the following occurs:
.The ignition is in ON/RUN.
.The power door locks are
activated.
.An illumination period of
20 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period will be canceled
and the interior lamps will remain on
because a door is open.
Parade Dimming
This feature automatically prohibits
the dimming of the instrument panel
displays in daylight while the
headlamps are on so that the
displays are still able to be seen.
Battery Load
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 bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge 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
of the power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on,
such as: 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.

to increase or decrease the
temperature of the air flowing
from the system.
Air Delivery Mode Control:
Turn clockwise or counterclockwise
to change the current airflow mode.
By positioning the right knob
between two modes, a combination
of those two modes is selected.
H(Vent): Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
between the instrument panel and
floor outlets. Some air is directed
toward the windshield and side
window outlets. Cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
6(Floor): Air is directed to the
floor outlets, with some of the air
directed to the windshield, side
window, and second row floor outlets. In this mode, the system
automatically selects outside air.
Recirculation cannot be selected
while in floor mode.
-(Defog):
This clears the
windows of fog or moisture. Air is
directed to the windshield, floor
outlets, and side window vents.
When this mode is selected, the
system turns off recirculation and
runs the air conditioning unless the
outside temperature is less than
4°C (40°F). Recirculation cannot be
selected while in the defog mode.
Do not drive the vehicle until all the
windows are clear.
0(Defrost): This clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield and side window vents,
with some to the floor vents. In this
mode, outside air is pulled inside
the vehicle. Recirculation cannot be
selected while in the defrost mode. The air conditioning system runs
automatically in this setting, unless
the outside temperature is less than
4°C (40°F). Do not drive the vehicle
until all windows are clear.
#(Air Conditioning):
Press to
turn the air conditioning system
on or off. An indicator light
comes on when A/C is on.
The air conditioning system does
not operate when the outside
temperature is below 4°C (40°F).
The indicator light flashes three
times and turns off when outside
conditions affect air conditioning
operation. This is normal.
For quicker cool down on hot days:
1. Open the windows to let hot air escape.
2. Select
Hmode.
3. Select
#.
4. Select the coolest temperature.

5. Select the highest fan speed.
6. Close the windows after thehot air has escaped.
7. Once the vehicle's interior temperature is below the outside
temperature, select
@mode
for faster cooling.
Using recirculation for long periods
of time could cause the air inside
the vehicle to become too dry.
To prevent this from happening,
after the inside of the vehicle has
cooled, turn the recirculation
mode off.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
@(Recirculation): Press to turn
the recirculation mode on or off.
An indicator light comes on when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must be
re‐selected when the engine is
turned on again.
This mode recirculates and helps
to quickly cool the air inside the
vehicle. It can be used to prevent
outside air and odors from entering
the vehicle.
The recirculation mode cannot be
used with floor, defrost, or defogging
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. The air
conditioning also comes on when
this mode is activated unless the
outside air temperature is less than
4°C (40°F). While in recirculation
mode the windows can fog when
the weather is cold and damp. To clear the fog, select either the
defog or defrost mode and increase
the fan speed.
