{WARNING
Leaving children, helpless adults,
or pets in a vehicle with the
windows closed is dangerous.
They can be overcome by
the extreme heat and suffer
permanent injuries or even death
from heat stroke. Never leave a
child, a helpless adult, or a pet
alone in a vehicle, especially with
the windows closed in warm or
hot weather.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof (if equipped).
Power Windows
{WARNING
Leaving children in a vehicle with
the keys 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 and they
could be seriously injured or killed
if caught in the path of a closing
window. Do not leave keys in a
vehicle with children.
When there are children in the
rear seat use the window lockout
button to prevent unintentional
operation of the windows.

debris. Wipe the sunroof seal and
roof sealing area using a clean
cloth, mild soap, and water. Do not

Instruments and Controls 5-7
two seconds to select the next
available variance zone. Repeat
this step until the appropriate
variance zone is displayed.
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 field 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, or seats during
the calibration procedure. 2. Press the vehicle information
button until PRESS
VTO
CALIBRATE 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
8 km/h (5 mph) 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.

7-14 Infotainment System
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
of the rear side windows may
affect radio reception or damage
the rear side window antenna.
Repairs would not be covered by
the warranty. Do not clear the
inside of the rear side windows
with sharp objects. Notice:
Do not apply aftermarket
glass tinting with metallic film.
The metallic film in some tinting
materials will interfere with or
distort the incoming radio
reception. Any damage caused to
the antenna due to metallic tinting
materials will not be covered by
the warranty.
Satellite Radio Antenna
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
(if equipped) may be affected if the
sunroof is open.
Audio Players
CD Player
Care of the CD Player
Do not add any label to a CD.
It could get caught in the CD. If a
CD is recorded on a personal
computer and a description label is
needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners for
CDs is not advised, due to the risk
of contaminating the lens of the CD
optics with lubricants internal to the
CD player mechanism.
