Section 2 Features and Controls
2-1

Convenience Net
Use the convenience net, located in the rear, to store
small loads as far forward as possible. The net
should not be used to store heavy loads.
Sunroof
The vehicle may have a sunroof. It includes a sliding
glass panel and a sunshade.
The sunroof control is
on the headliner, by the
map lamps.
The sunroof control works only when the ignition is on
or in ACC/ACCESSORY, or when Retained Accessory
Power (RAP) is active. SeeRetained Accessory
Power (RAP) on page 2-22.To raise the sunroof to the vent position, open the
sunshade by hand, then press the back of the control.
Push and hold the front of the control to close the
sunroof from the vent position.
With the sunroof in the vent position, press and release
the back of the control to express-open the sunroof.
The sunshade will automatically open with the sunroof.
To stop the express-open function, press the back
of the control again.
To close the sunroof, press and hold the front of the
control. To stop the sunroof, release the control.
The sunshade must be closed manually.
The sunroof panel cannot be opened or closed if your
vehicle has an electrical failure.

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 option button until COMPASS
CALIBRATION displays.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display CALIBRATION BEGUN 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 FINISHED
for a few seconds when the calibration is complete.
The DIC display will then return to COMPASS
CALIBRATION.

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 lines on the glass are not damaged. If the
inside surface is damaged, it could interfere with radio
reception. For proper radio reception, the antenna
connector needs to be properly attached to the post
on the glass.
If a cellular telephone 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.
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.
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.
Chime Level Adjustment
The radio is used to adjust the vehicle’s chime level.
To change the volume level of the chime, press and hold
pushbutton 6 with the ignition on and the radio power off.
The volume level will change from the normal level to
loud, and LOUD will appear on the radio display. To
change back to the default or normal setting, press and
hold pushbutton 6 again. The volume level will change
from the loud level to normal, and NORMAL will appear
on the radio display. Removing the radio and not
replacing it with a factory radio or chime module will
disable vehicle chimes.
