Manual-Open/Manual-Close:To open the sunroof
press and hold the rear of the driver's side switch until
the sunroof reaches the desired position. To close the
sunroof, press and hold the front of the driver's side
switch until the sunroof reaches the desired position.
When the sunroof is opened, an air deflector will
automatically raise. The air deflector will retract when
the sunroof is closed.
Express-Open/Express-Close: To express-open the
sunroof, fully press and release the rear of the driver's
side switch. The sunroof will open automatically. To stop
the sunroof partway, press the switch a second time. To
express-close the sunroof, fully press and release the
front of the driver's side switch. The sunroof will close
automatically. To stop the sunroof partway, press the
switch a second time.
The sunroof also has a sunshade which you can pull
forward to block sun rays. The sunshade must be
opened and closed manually. Anti-Pinch Feature (Crew Cab Only):
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 open halfway, and the air deflector will raise. To
close the sunroof once it has re-opened, refer to the
Express-Close or Manual-Close functions described
previously. If the sunroof is in the vent position, and
there is an object in the path of the sunroof when it
closing, the anti-pinch feature will detect the object and
stop the sunroof. To close the sunroof once it has
stopped, refer to the Vent functions described
previously.
Do not leave the sunroof open for long periods of time
while the vehicle is not in use. Debris can collect in the
tracks and damage the sunroof operation and plug the
water draining system.

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, seats, etc. 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 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.

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 fixed 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.
