number on the map.
Zones 1 through 15 are
available.
3. Press
Vto scroll through and
select the appropriate
variance zone.
4. Press
3until the vehicle
heading, for example, N for
North, is displayed in the DIC. 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.

5-36 Instruments and Controls
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. SeeAirbag
Readiness Light on page 5-15 and
Airbag System on page 3-16 for
more information.
Security 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 2-11 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.
SERVICE VEHICLE SOON
This message displays when a
non-emissions related malfunction
occurs. Have the vehicle serviced
by your dealer as soon as possible.
STARTING DISABLED
SERVICE THROTTLE
This message displays if the starting
of the engine is disabled due to the
electronic throttle control system.
Have the vehicle serviced by your
dealer immediately.
This message only appears while
the ignition is in ON/RUN, and will
not disappear until the problem is
resolved.
This message cannot be
acknowledged.
Tire Messages
CHECK TIRE PRESSURE or
TIRE LOW ADD AIR TO TIRE
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays when the
pressure in one or more of the tires
is low. The low tire pressure warning
light will also come on. See Tire
Pressure Light on page 5-23. This
message will also indicate which tire
needs to be checked. You can

6-6 Lighting
Reading Lamps
For vehicles with reading lamps,
press the button next to each lamp
to turn it on or off.
The vehicle may also have reading
lamps in other locations. The lamps
cannot be adjusted.
Lighting Features
Entry/Exit Lighting
The vehicle has an illuminated
entry/exit feature.
The dome lamps come on if the
E
DOME 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 vehiclehas 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

H(Vent):Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
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.1(Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield, with some to the floor
outlets and front side windows. The
air conditioning compressor might
turn on in this setting to dehumidify
the air.

4. 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
If equipped 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.
{Caution
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
the vehicle warranty.

8-4 Climate Controls
Rear Heating System
If equipped, the rear heating system
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 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): This turns the rear
heating system off.
Rear Climate Control
System
If equipped with a rear heating and
air conditioning system, it controls
the temperature, fan speed, and air
delivery for the rear seat
passengers only. The front climate
control panel is in the overhead
console between the driver and
front passenger.
