Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
Sunroof (if equipped)
Power to the audio system will work up to 10 minutes or
until the driver’s door is opened. Power to the windows
or sunroof will work up to 10 minutes or until any
door is opened. For an additional 10 minutes of
operation, close all the doors and turn the key to
ON/RUN and then back to LOCK/OFF.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to PARK (P) or NEUTRAL (N).
The engine will not start in any other position -- this
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.If your vehicle has the keyless access system, put your
foot on the brake pedal and turn the ignition control
knob to the START position. When the engine begins
cranking, let go of the ignition control knob, it will return
to the ON/RUN position.
If the transmitter is not in the vehicle or something is
interfering with the transmitter, the Driver Information
Center (DIC) will display Electronic Key Not Detected.
SeeDIC Warnings and Messages on page 3-56for
more information.
If the battery in the keyless access transmitter needs
replacing, the DIC displays Replace Battery In Remote
Key. The vehicle can still be driven. See “Battery
Replacement” underKeyless Access System Operation
on page 2-10for more information.
Notice:Do not try to shift to P (Park) if your
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when your
vehicle is stopped.

The net is not for heavier loads. Store them as far forward
as you can.
Sunroof
If your vehicle has a power sunroof it will only operate
when the ignition is turned on, or in ACC/ACCESSORY,

and stop the sunroof from closing at the point of
the obstruction. The sunroof will then return to the
full-open or vent position. To close the sunroof once
it has re-opened press and hold the front of the
passenger’s side switch.

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 eld
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,
sunroof, climate controls, seats, etc. during
the calibration procedure.
2. Press the vehicle information button until
Press
VTo Calibrate Compass displays.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display Calibrating Drive In Circles.
Drive the vehicle in tight circles at less than
5 mph (8 km/h) 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.

XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite radio
signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy foliage,
bridges, garages, or tunnels may cause loss of XM
signal for a period of time. The radio may display
No XM Signal to indicate interference.
Cellular Phone Usage
Cellular phone usage may cause interference with your
vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
causes an increased level of static while listening to
the radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.
Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Make sure that
the inside surface of the rear window is not scratched
and that the grid lines on the glass are not damaged.
If the inside surface is damaged, it could interfere
with radio reception.Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by your warranty. Do not clear
the inside rear window with sharp objects.
Notice:Do not apply aftermarket glass tinting
with metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by your warranty.
Because this antenna is built into the rear window,
there is a reduced risk of damage caused by car washes
and vandals.
XM™ Satellite Radio Antenna System
The XM Satellite Radio antenna is located on the roof of
the vehicle. Keep this antenna clear of snow and ice
build up for clear radio reception.
If the vehicle has a sunroof, the performance of the
XM system may be affected if the sunroof is open.
Loading items onto the roof of the vehicle can interfere
with the performance of the XM system. Make sure
the XM Satellite Radio antenna is not obstructed.
