Window lock
The window lock feature allows only
the driver and front passenger to
operate the power windows.
To lock out all the window controls
(except for the driver and front
passenger) press the right side of
the control. Press the left side to
restore the window controls.
Accessory delay
With accessory delay, the window switches, audio system, and moon roof

INTERIOR MIRROR
The interior rear view mirror has two pivot points on the support arm
which lets you adjust the mirror UP or DOWN and from SIDE to SIDE.
WARNING:Do not adjust the mirror while the vehicle is in
motion.
Automatic dimming interior rear view mirror
Your vehicle is equipped with an
interior rear view mirror and a
driver’s side exterior mirror that
have auto-dimming function. The
electronic day/night mirrors will
change from the normal (high
reflective) state to the non-glare
(darkened) state when bright lights (glare) reach the interior mirror.
When the interior mirror detects bright light from behind the vehicle, the
interior rear view mirror and the driver’s side exterior mirror will
automatically adjust (darken) to minimize glare.
The mirror will automatically return to the normal state whenever the
vehicle is placed in R (Reverse) to ensure a bright clear view when
backing up.
Do not block the sensors on the front and back of the interior
rear view mirror since this may impair proper mirror
performance.

Compass display
Select this function from the INFO menu. Press the INFO button
repeatedly until the Compass and Odometer are displayed. (Do not
select Trip, DTE, or AFE. The top of the message center must be blank).
The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antenna. Magnetic
or metallic objects placed in, on or near the vehicle may also affect
compass accuracy.
Usually, when something affects the compass readings, the compass will
correct itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary. Refer toCompass zone/calibration
adjustment.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
degrees between adjacent zones and will become noticeable as the
vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer toCompass zone/calibration adjustment.
Compass zone/calibration adjustment
Perform this adjustment in an open area free from steel structures and
high voltage lines.
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.
1. Turn ignition to the on position.
2. Start the engine.
3. Press the INFO button repeatedly until the Compass and Odometer
are displayed. (Do not select Trip, DTE, or AFE. The top of the message
center must be blank).
Note:If the compass displaysCAL 000000.0 miinstead of heading
information, the compass will need to be calibrated. Slowly drive the
vehicle in a circle (less than 3 mph [5 km/h]) until theCALindicator
changes to display compass heading. This may take up to three circles to
complete calibration.

WARNING:To minimize the risk of neck injury in the event of a
crash, head restraints must be installed properly.
Adjusting the front power seat
WARNING:Never adjust the driver’s seat or seatback when the
vehicle is moving.
WARNING:Do not pile cargo higher than the seatbacks to
reduce the risk of injury in a collision or sudden stop.
WARNING:Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING:Reclining the seatback can cause an occupant to
slide under the seat’s safety belt, resulting in severe personal
injuries in the event of a collision.
WARNING:Sitting improperly out of position or with the seat
back reclined too far can take off weight from the seat cushion
and affect the decision of the front passenger sensing system, resulting
in serious injury or death in a crash. Always sit upright against your
seatback, with your feet on the floor.
WARNING:To reduce the risk of possible serious injury: Do not
hang objects off seat back or stow objects in the seatback map
pocket (if equipped) when a child is in the front passenger seat. Do
not place objects underneath the front passenger seat or between the
seat and the center console (if equipped). Check the “passenger airbag
off” or “pass airbag off” indicator lamp for proper airbag status. Refer
toFront passenger sensing systemsection for additional details.
Failure to follow these instructions may interfere with the front
passenger seat sensing system.
