Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime
will sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
The following accessories on your vehicle can be used
for up to 10 minutes after the engine is turned off.
Audio System
Audio Steering Wheel (if equipped)
Clock
Power Windows
Sunroof (if equipped)
Power to these accessories works up to 10 minutes or
until the driver’s door is opened.The instrument panel cluster lights stay on for a few
seconds, then will go out. Once the driver’s door
is opened, the power shuts off to these accessories.
Your vehicle has a feature designed to protect the
battery against drainage. For more information
seeInadvertent Power Battery Saver on page 3-19and
Electric Power Management on page 3-19.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position – this is a
safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
2-22

If your vehicle has a power
sunroof, the switches are
located on the headliner.
To express-open the sunroof press the rear of the driver
side switch to the second detent position, and release.
To stop the sunroof from express opening, press
the switch again. The sunroof has a comfort stop feature
which stops the sunroof from opening to the full-open
position. From the comfort stop position, press the rear
of the driver side switch a second time to open the
sunroof to the full-open position. If the sunshade is in
the closed position, it will open with the sunroof, or it can
be opened manually.To close the sunroof, press the front of the driver side
switch to the second detent position, and release.
To vent the sunroof press and hold the back of the
passenger side switch until the vent reaches the desired
position. Press the front of the passenger side switch
to close the sunroof.
If an object is in the path of the sunroof while it is
closing, the anti-pinch feature will detect the object 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 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
V
TO CALIBRATE COMPASS.
DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another. Some messages may not require immediate
action, but you can press the set/reset button to
acknowledge that you received the message and clear it
from the DIC display. Pressing any of the DIC buttons
also acknowledges and clears any messages. Some
messages cannot be cleared from the DIC display
because they are more urgent. These messages require
action before they can be cleared. You should take
any messages that appear on the display seriously and
remember that clearing the messages will only make
the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
AUTOMATIC LIGHT CONTROL OFF
This message displays when the automatic headlamps
are turned off. SeeExterior Lamps on page 3-14for
more information.
AUTOMATIC LIGHT CONTROL ON
This message displays when the automatic headlamps
are turned on. SeeExterior Lamps on page 3-14for
more information.

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.
If static is heard on the radio, when the rear window
defogger is turned on, it could mean that a defogger grid
line has been damaged. If this is true, the grid line
must be repaired.If adding a cellular telephone to your vehicle, and the
antenna needs to be attached to the glass, make
sure that the grid lines for the AM-FM antenna are not
damaged. There is enough space between the grid lines
to attach a cellular telephone antenna without interfering
with radio reception.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on the roof
of your vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
If your vehicle has a sunroof, the performance of the
XM™ system may be affected if the sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of the XM™ system. Make sure
the XM™ Satellite Radio antenna is not obstructed.
