{CAUTION
Leaving children in a vehicle with
the ignition key is dangerous for
many reasons, children or others
could be badly injured or even
killed. They could operate the
power windows or other controls
or even make the vehicle move.
The windows will function with the
keys in the ignition and children
could be seriously injured or killed
if caught in the path of a closing
window. Do not leave the keys in
a vehicle with children.The key is used for the ignition and
all door locks.
The key has a bar-coded key tag
that the dealer/retailer or quali ed
locksmith can use to make new
keys. Store this information in a safe
place, not in the vehicle.
See your dealer/retailer if a
replacement key or additional
key is needed.
2-2 Features and Controls
Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct key,
make sure it is all the way in, and
turn it only with your hand. If the
key cannot be turned by hand, see
your dealer/retailer.
((LOCK/OFF):This position
locks the ignition and transmission.
The key can be removed in

closed position and latch before
driving. If the cover is removed,
always store it outside of the
vehicle. When it is replaced,
always be sure that it is securely
reattached.
3. Remove the cover from the
vehicle and store outside of
the vehicle.
Sunroof
The vehicle may have a sunroof
over the front seats and a rear
sunroof over the second row seats.
The rear sunroof does not open.
The switches to operate the
front sunroof and rear sunshade are

2-54 Features and Controls
2. Find the vehicle’s current
location and variance zone
number on the map.
Zones 1 through 15 are available.
3. Press the set/reset button
to scroll through and select the
appropriate variance zone.
4. Press the trip/fuel button until 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 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 the previous menu.
Instrument Panel 3-55
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.
Multi-Band Antenna
The multi-band antenna is located
on the roof of the vehicle. This
type of antenna is used with
the AM/FM radio, as well as
OnStar
®and the XM™ Satellite
Radio Service System, if the vehicle
has these features. Keep this
antenna clear of snow and ice build
up for clear radio reception. If the
vehicle has a sunroof, the
performance of the radio system
may be affected if the sunroof
is open. Loading items onto the roof
of the vehicle can interfere with
the performance of the radio system
and, if the vehicle has this feature,
OnStar
®. Make sure the multi-band
antenna is not obstructed.
