WARNING LIGHTS AND CHIMES
Standard instrument cluster
Optional instrument cluster
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Check engine:TheCheck engine
indicator light illuminates when the
ignition is first turned to the ON
position to check the bulb. Solid
illumination after the engine is
started indicates the On Board Diagnostics System (OBD-II) has
detected a malfunction. Refer toOn board diagnostics (OBD-II)in the

left or right turn signal or the
hazard lights are turned on. If the
indicators stay on or flash faster, check for a burned out bulb.
High beams:Illuminates when the
high beam headlamps are turned on.
MESSAGE CENTER INDICATOR LIGHTS (IF EQUIPPED)
Speed control:Illuminates when
the speed control is activated. Turns

RADIO FREQUENCIES
AM and FM frequencies are established by the Federal Communications
Commission (FCC) and the Canadian Radio and Telecommunications
Commission (CRTC). Those frequencies are:
AM - 530, 540–1700, 1710 kHz
FM- 87.7, 87.9–107.7, 107.9 MHz
RADIO RECEPTION FACTORS
There are three factors that can affect radio reception:
•Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
•Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
•Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.
CASSETTE/PLAYER CARE
Do:
•Use only cassettes that are 90 minutes long or less.
•Tighten very loose tapes by inserting a finger or pencil into the hole
and turning the hub.
•Remove loose labels before inserting tapes.
•Allow tapes which have been subjected to extreme heat, humidity or
cold to reach a moderate temperature before playing.
•Clean the cassette player head with a cassette cleaning cartridge after
10–12 hours of play to maintain good sound/operation.
Don’t:
•Expose tapes to direct sunlight, extreme humidity, heat or cold.
•Leave tapes in the cassette player for a long time when not being
played.

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 predetermined period
of time after the ignition switch is
turned to OFF.
•To turn autolamps on, rotate the
control counterclockwise to the
next position from OFF.
•To turn autolamps off, rotate the control clockwise past OFF to the
parking lamp position
, then back to OFF.
The headlamps will turn on under the following conditions:
1. Headlamp switch is turned to the “headlamps on position”.
2. With the ignition in ON or START, wipers turned on and the headlamp
switch in the autolamp position.
Daytime running lamps (DRL) (if equipped)
Turns the lowbeam headlamps on with a reduced output. To activate:

Always remember to turn on your headlamps at dusk or during
inclement weather. The Daytime Running Light (DRL) System
does not activate your 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.
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.
PANEL DIMMER CONTROL

instrument panel during headlamp
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.
Domelamp Control
The panel dimmer control also controls the domelamp operation.

•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 a qualified service technician.
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.
TURN SIGNAL CONTROL
•Push down to activate the left
turn signal.
•Push up to activate the right turn
signal.
The flash rate of the turn signal will speed up considerably if the left or
right turn lamp bulb (front or rear) is burned out.
Cornering lamps
When the turn signal is used and the headlamps are on, the cornering
lamps will light either the right or left side depending on the direction of
the turn.

lamp. With the lens in the flat
position, the courtesy lamp lights
when:
•Any door is opened.
•The panel dimmer thumbwheel is
rotated fully to the right past
detent.
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.
Replacing exterior bulbs
Check the operation of all the bulbs frequently.
Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to assure 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.
