5. If calibration is necessary,calibrate the compass. See
“Compass Calibration
Procedure” following.
Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an open
parking lot, where driving the
vehicle in circles is not a danger.
It is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated. If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be a
strong magnetic field interfering with
the compass. Such interference
may be caused by a magnetic CB or
cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle,
move the magnetic item, then turn
on the vehicle and calibrate the
compass.
To calibrate the compass, use the
following procedure:
Compass Calibration Procedure
1. Before calibrating the compass,
make sure the compass zone is
set to the variance zone in which
the vehicle is located. See
“Compass Variance (Zone)
Procedure” earlier in this
section. Do not operate any switches
such as window, climate
controls, seats, etc. during the
calibration procedure.
2. Press
Tuntil PRESSVTO
CALIBRATE COMPASS
displays.
3. Press
Vto start the compass
calibration.
4. The DIC will display CALIBRATING: DRIVE IN
CIRCLES. Drive the vehicle in
tight circles at less than 8 km/h
(5 mph) to complete the
calibration. The DIC will display
CALIBRATION COMPLETE
for a few seconds when the
calibration is complete. The DIC
display will then return to
PRESS
VTO CALIBRATE
COMPASS.

STABILITRAK OFF may also
display when the stability control
has been automatically disabled.
There are several conditions that
can cause this message to appear.
.One condition is overheating,
which could occur if StabiliTrak
activates continuously for an
extended period of time.
.The message also displays if the
brake system warning light is on.
SeeBrake System Warning
Light on page 5‑23.
.The message could display if the
stability system takes longer
than usual to complete its
diagnostic checks due to driving
conditions.
.The message displays if an
engine or vehicle related
problem has been detected and
the vehicle needs service. See
your dealer. The message turns off as soon as
the conditions that caused the
message to be displayed are no
longer present.
Airbag System Messages
SERVICE AIR BAG
This message displays if there is a
problem with the airbag system.
Have your dealer inspect the
system for problems. See
Airbag
Readiness Light on page 5‑16 and
Airbag System on page 3‑19 for
more information.
Anti-theft Alarm System
Messages
SERVICE THEFT DETERRENT
SYSTEM
This message displays when there
is a problem with the theft-deterrent
system. The vehicle may or may not
restart so you may want to take the
vehicle to your dealer before turning off the engine. See
Immobilizer
Operation on page 2‑13 for more
information.
WAIT TO START
This message displays briefly when
the theft-deterrent system has
initially found incorrect conditions
within the vehicle and is making a
double check. If your vehicle does
not start soon after, try to start it
again. If it still does not start, have
your vehicle serviced by your
dealer.
Service Vehicle Messages
SERVICE A/C SYSTEM
This message displays when the
electronic sensors that control the
air conditioning and heating
systems are no longer working.
Have the climate control system
serviced by your dealer if you notice
a drop in heating and air
conditioning efficiency.

Lighting 6-7
Lighting Features
Entry/Exit Lighting
The vehicle has an illuminated
entry/exit feature.
The dome lamps come on if the
EDOME OFF button is in the
extended position, when a door is
opened or the key is removed from
the ignition.
Battery Load
Management
The vehicle may have 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 the
power that is 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.
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 SERVICE
BATTERY CHARGING SYSTEM.
If this messages displays, it is
recommended that the driver reduce
the electrical loads as much as
possible. See
Battery Voltage and
Charging Messages on page 5‑34.
Battery Power Protection
This feature shuts off the dome
lamps if they are left on for more
than 10 minutes when the ignition is
in LOCK/OFF. This helps to prevent
the battery from running down.

between the instrument panel and
floor outlets, with some air directed
toward the windshield.
6(Floor): Air is directed to the
floor outlets with some air directed
to the windshield and side windows.
-(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 might turn on in this
setting to dehumidify the air.

D. Rear Window Defogger
On hot days, open the windows to
let hot inside air escape; then close
them. This helps to reduce the time
needed for the vehicle to cool down
and the system operates more
efficiently.
#(Air Conditioning): Cools and
dehumidifies the air inside of the
vehicle.
V(Maximum Air Conditioning):
Cools the air inside the vehicle
faster, by recirculating the inside air.
Rear Window Defogger
For vehicles with a rear window
defogger, a warming grid is used to
remove fog or frost from the rear
window.
It only works when the ignition is in
ON/RUN.
1(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger turns off
several minutes after the button is
pressed. If turned on again, the
defogger will run for several more
minutes before turning off. The
defogger can also be turned off by
turning off the engine.

Do not drive the vehicle until all the
windows are clear.
Notice:Do not use a razor blade
or sharp object to clear the inside
rear window. Do not adhere
anything to the defogger grid
lines in the rear glass. These
actions may damage the rear
defogger. Repairs would not be
covered by your warranty.
Rear Heating System
For vehicles with a rear heating
system, it lets you adjust the
amount of air flowing into the rear of
the vehicle, from the front-seating
area. This feature works with the
main climate-control system in the
vehicle.AUX: The thumbwheel for this
system is located in the instrument
panel switchbank below the audio
system.
9(Fan): Turn the thumbwheel up
or down to increase or decrease the
amount of heated air sent to the
rear-seating area.
Q(High): This position supplies the
most amount of heat to the
rear-seating area.
c(Medium): This position
supplies half the amount of heat to
the rear‐seating area.
R(Low): This position supplies the
least amount of heat to the
rear-seating area.
9(Off): Turns the rear heating
system off.
