Radio reception factors
There are certain factors that may effect your radio reception.
•Distance/strength.The further an FM signal travels, the weaker it is.
The listenable range of the average FM station is approximately 40 km
(24 miles). This range can be affected by “signal modulation.” Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
•Terrain.Hills, mountains and tall buildings between your vehicle’s
antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its “shadow”) returns your reception to normal.
•Station overload.Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
Principles of GPS (global positioning system) operation
Your system directs you based on information derived from global
positioning satellites, road maps stored on the DVD, sensors in your
vehicle and the desired destination. The system compiles all necessary
information to guide you to your selected destination. Space satellites
determine the vehicle’s current location and transmit position and time
signals to your car.
If the vehicle has been parked for a long period of time, the navigation
function may be temporarily unresponsive. The navigation system will
operate reliably again once GPS reception is available for a few minutes.
Limited GPS reception
System performance may be adversely affected if GPS reception is
interrupted or interference occurs over a distance of several miles. The
following are possible causes for GPS reception being interrupted. If the
vehicle is:
•in multi-story parking garages
•in tunnels and under bridges
•inside or in between buildings
•by forests or tree-lined avenues
•in heavy rain showers and thunderstorms
•in valleys and in mountainous regions

a period of time.

OPERATING TIPS
•To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•To reduce humidity build up inside the vehicle: do not drive with the
recirculation control on or the system turned off.
•To improve the A/C cool down, drive with the windows slightly open
for 2–3 minutes after start up or until the vehicle has been “aired out.”
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
To aid in side window defogging/demisting in cold weather:
1. Select
.
2. Select A/C.
3. Adjust the temperature control to maintain comfort.
4. Set the fan to the highest speed.
5. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.

HEADLAMP CONTROL
Turns the lamps off.
Turns on the parking
lamps, instrument panel lamps,
license plate lamps and tail lamps.
Turns the headlamps on.
Autolamp control
The autolamp system provides light
sensitive automatic on-off control of
the exterior lights normally
controlled by the headlamp control.
The autolamp system also keeps the
lights on for a preselected period of
time after the ignition switch is
turned to OFF.
The autolamps are turned on at
night or when the front wipers are
turned on.
•To turn autolamps on, rotate the control counterclockwise. The
preselected time lapse is adjustable up to approximately three
minutes. See the programming procedure following.
•To turn autolamps off, rotate the control clockwise to the off position
(O).
The amount of time the autolamps stay on can be programed by doing
the following:
1. Turn the ignition to OFF.
2. Turn the headlamp switch to the Autolamp position.
Note:Steps 3 through 5 need to be performed within 10 seconds.
3. Turn the headlamp switch to OFF.
4. Turn the ignition to RUN and then back to OFF.
5. Turn the headlamp switch to the Autolamp position.
6. Wait the desired amount of time for delay, then turn the headlamp
switch to OFF.

Foglamp control (if equipped)
The foglamps can be turned on
when the headlamp control is pulled
toward you and is in any of the
following positions:
•Parking lamps
•Low beams
•Autolamps (when active)
Foglamps will turn off when the
highbeams are activated.
High beams
Push the lever toward the
instrument panel to activate. Pull
the lever towards you to deactivate.
Flash to pass
Pull toward you slightly to activate
and release to deactivate.
Daytime running lamps (DRL) (if equipped)
The daytime running light system turns the headlamps on, with a
reduced light output, when:
•the ignition is in RUN,
•the transmission is not in P (Park),
•the headlamp system is not turned on by another feature such as
using the headlamp control or Autolamp.

Always remember to turn on your headlamps at dusk or during
inclement weather. The Daytime Running Light (DRL) System
does not activate the tail lamps and generally may not provide
adequate lighting during these conditions. Failure to activate your
headlamps under these conditions may result in a collision.
PANEL DIMMER CONTROL
Use to adjust the brightness of the
instrument panel during headlight
and parklamp operation.
•Rotate the thumbwheel from left
to right to brighten the
instrument panel.
•Rotate the thumbwheel from right
to left to dim the instrument
panel.
During full daylight, the instrument panel will still be visible with the
headlamps operating.
Domelamp Control
The panel dimmer control also controls the domelamp operation.
•Rotate the thumbwheel fully to the right, past detent to activate the
domelamp.
•In order to turn off the domelamp, rotate the thumbwheel to the left.
AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident the alignment of your headlamps
should be checked by your authorized dealer.
Vertical aim adjustment
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.

•(1) 8 feet (2.4 meters)
•(2) Center height of lamp to
ground
•(3) 25 feet (7.6 meters)
•(4) Horizontal reference line
2. Measure the height of the
headlamp bulb center from the
ground and mark an 8 foot (2.4
meter) horizontal reference line on
the vertical wall or screen at this
height (a piece of masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood.
4. On the wall or screen you will
observe an area of high intensity
light. The top of the high intensity
area should touch the horizontal
reference line, if not, the beam will
need to be adjusted.
To see a clearer light pattern for
adjusting, you may want to block
the light from one headlamp while
adjusting the other.
5. Locate the vertical adjuster on
each headlamp. Usinga4mm
wrench, turn the adjuster either
clockwise (to adjust down) or
counterclockwise (to adjust up).
The horizontal edge of the brighter
light should touch the horizontal
reference line.
6. HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS
NON-ADJUSTABLE.
7. Close the hood and turn off the lamps.

INTERIOR LAMPS
Map/Courtesy lamps
To turn on the map lamps, press the
map lamp control.
Rear courtesy/reading lamps
The courtesy lamp lights when:
•any door is opened.

BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.

Using the right bulbs
Replacement bulbs are specified in the following chart. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to ensure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.
