Section 2 Features and Controls
2-2

C (ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The switch
stays in this position when the engine is running.
The transmission is also unlocked in this position
on automatic transmission vehicles.
If you leave the key in the ACC/ACCESSORY or ON/
RUN position with the engine off, the battery could be
drained. You may not be able to start the vehicle if the
battery is allowed to drain for an extended period of time.
D (START):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Sunroof
Power Windows
The sunroof and power windows will continue to work
up to 10 minutes after the key is turned to LOCK/OFF
or until any door is opened. The radio will continue
to work for up to 10 minutes after the key is turned
to LOCK/OFF or until the driver door is opened.
Starting the Engine
Move the shift lever to P (Park) or N (Neutral).
The engine will not start in any other position.
To restart the engine when the vehicle is already
moving, use N (Neutral) only.
Notice:Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when the
vehicle is stopped.
2-29

Sunroof
The vehicle may have
a power sliding sunroof.
The ignition must be
in ON/RUN or ACC/
ACCESSORY or Retained
Accessory Power (RAP)
must be active.
SeeRetained Accessory Power (RAP) on page 2-29.
The switch used to operate the sunroof is located in
the overhead console.
Express-Open/Close Sunroof
The sunroof has a feature which allows the sunroof
panel to be opened or closed without continuously
pressing the switch. The express-open can be stopped
at any time by pushing the front of the switch a
second time.
The sunroof has four positions:
Comfort open stop:To open the sunroof and
sunshade, press the rear of the switch quickly and
release. The glass panel will open to an interim
position that reduces wind noise. For information on
using the sunshade, see “Sunshade Operation” later.
Full open stop:To open the sunroof further, press
the rear of the switch quickly once more.
Express close:To close the sunroof, press the front
of the switch quickly and release.
Vent:The vent position allows the rear of the sunroof
to be opened and tilted upward. With the sunroof in
the fully closed position, press and hold the front of
the switch until the sunroof reaches the desired vent
position or until it stops moving. To close the sunroof
from the vent position, press and hold the rear of the
switch until the sunroof is fully closed.
Do not leave the sunroof open for long periods of time
as debris may collect in the tracks.
2-68

Anti-Pinch Protection Feature
If something gets caught between the glass panel
and roof frame while the sunroof is closing, the glass
panel will stop and open half way, and the deector
will raise fully.
If something gets caught between the glass panel
and the roof frame during the tilt down operation,
the glass panel will stop and open fully.
If the sunroof panel receives a strong impact, the
anti-pinch protection feature may work even if nothing
gets caught between the glass panel and roof frame.
Sunshade Operation
The sunshade will open automatically when opening the
sunroof.
However, it can manually be pulled shut after the
sunroof is closed. To adjust the sunshade, push it
backward or pull it forward to the desired position.
The sunshade cannot be adjusted further than
the current closed position of the sunroof.
Notice:If you force the sunshade forward of the
sliding glass panel, damage will occur and the
sunroof may not open or close properly. Always
close the glass panel before closing the sunshade.

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 COMPAS (Compass)
displays. Or, if the vehicle does not have DIC
buttons, press the trip odometer reset stem until
CALIBRATE COMPASS displays.
3. Press the set/reset button to start the compass
calibration. Or, if the vehicle does not have DIC
buttons, press and hold the trip odometer reset stem
for two seconds 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 the
previous menu.
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 any of the DIC buttons on the instrument
panel or the trip odometer reset stem on the instrument
panel cluster to acknowledge that you received the
messages and to clear them from the display.
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.
CHANGE ENGINE OIL SOON
This message displays when the engine oil needs to
be changed. When you change the engine oil, be sure
to reset the CHANGE ENGINE OIL SOON message. See
Engine Oil Life System on page 5-18for information on
how to reset the message. SeeEngine Oil on page 5-15
andScheduled Maintenance on page 6-4for more
information.

AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause station
frequencies to interfere with each other. For better radio
reception, most AM radio stations boost the power levels
during the day, and then reduce these levels during the
night. Static can also occur when things like storms and
power lines interfere with radio reception. When this
happens, try reducing the treble on the radio.
FM Stereo
FM signals only reach about 10 to 40 miles
(16 to 65 km). Although the radio has a built-in electronic
circuit that automatically works to reduce interference,
some static can occur, especially around tall buildings
or hills, causing the sound to fade in and out.
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 the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause interference with the
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.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged as long as it is securely attached
to the base. If the mast becomes slightly bent, straighten
it out by hand. If the mast is badly bent, replace it.
Occasionally check to make sure the antenna is
tightened to its base. If tightening is required, tighten
by hand until fully seated plus one quarter turn.
XM™ Satellite Radio Antenna
System
The XM Satellite Radio antenna is located on the roof of
the vehicle. Keep the antenna clear of obstructions for
clear radio reception.
If the vehicle has a sunroof, the performance of the XM
system may be affected if the sunroof is open.
