located on the floor console. To
activate, press and release the
control to cycle through the color
choices plus the off state.
The lights come on whenever the ignition is in either the on or accessory
position.
Note:The ambient lights will stay on until the ignition is placed in the
off position and either of the front doors are opened or the accessory
delay timer expires.

The interior lamps will automatically extinguish after 10 minutes when
the ignition key is in the off position, a door has been left open or the
interior lamp controls are in the on position.
BULB REPLACEMENT
Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
Examples of acceptable condensation are:
•Presence of thin mist (no streaks, drip marks or droplets)
•Fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
•Water puddle inside the lamp
•Large water droplets, drip marks or streaks present on the interior of
the lens

ELECTRONIC COMPASS (IF EQUIPPED)
The compass heading is displayed in the center stack display.
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 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 adjustment.
Compass zone adjustment
1. Determine which magnetic zone
you are in for your geographic
location by referring to the zone
map.
2. Turn ignition to the on position.
3. Start the engine.
4. Press the SETUP control to select
the Update Zone function and
display the current ZONE XX in the
center stack display.

The sliding tray and inside bin can
be hooked on the side or rear of the
console for extra storage.
AUXILIARY POWER POINT (12VDC)
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this will damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
Auxiliary power points can be found in the following locations:
•On the instrument panel
•On the rear side of the center console
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer toFuses and
relaysin theRoadside Emergencieschapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
•do not use the power point longer than necessary when the engine is
not running,
•do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
Always keep the power point caps closed when not being used.
