SERVICE INFORMATION
The Daytime Running Lights (Headlamps) System
is installed on vehicles manufactured for sale in Can-
ada only. The headlamps are illuminated when the
ignition switch is turned to the ON position. The
DRL module receives a vehicle-moving signal from
the vehicle speed sensor. This provides a constant
headlamps-oncondition as long as the vehicle is
moving. The lamps are illuminated at less than 50
percent of normal intensity.

GENERAL INFORMATION
Each vehicle is equipped with various lamp assem-
blies. A good ground is necessary for proper lighting
operation. Grounding is provided by the lamp socket
when it comes in contact with the metal body, or
through a separate ground wire.
When changing lamp bulbs check the socket for
corrosion. If corrosion is present, clean it with a wire
brush and coat the inside of the socket lightly with
Mopar Multi-Purpose Grease or equivalent.
DIAGNOSTIC PROCEDURESÐYJ
When a vehicle experiences problems with the
headlamp system, verify the condition of the batteryconnections, charging system, headlamp bulbs, wire
connectors, relay, high beam dimmer switch and
headlamp switch. Refer to Group 8W, Wiring Dia-
grams for component locations and circuit informa-
tion.
Always begin any diagnosis by testing all of the
fuses and circuit breakers in the system. Refer to
Group 8W, Wiring Diagrams.

HEADLAMP ALIGNMENTÐYJ
Headlamps can be aligned using the screen method
provided in this section. Alignment Tool C4466-A or
equivalent can also be used. Refer to instructions
provided with the tool for proper procedures.The
preferred headlamp alignment setting is 0 for
the left/right adjustment and 1(down for the
up/down adjustment.
HEADLAMP ALIGNMENT PREPARATIONÐYJ
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Correct defective components that could hinder
proper headlamp alignment.
(3) Verify proper tire inflation.
(4) Clean headlamp lenses.
(5) Verify that luggage area is not heavily loaded.
(6) Fuel tank should be FULL. Add 2.94 kg (6.5
lbs.) of weight over the fuel tank for each estimated
gallon of missing fuel.

HEADLAMP/FOG LAMP ADJUSTMENT USING
ALIGNMENT SCREENÐYJ
ALIGNMENT SCREEN PREPARATION
(1) Position vehicle on a level surface perpendicu-
lar to a flat wall 7.62 meters (25 ft) away from front
of headlamp lens (Fig. 1).
(2) If necessary, tape a line on the floor 7.62
meters (25 ft) away from and parallel to the wall.
(3) Measure from the floor up 1.27 meters (5 ft)
and tape a line on the wall at the centerline of the
vehicle. Sight along the centerline of the vehicle
(from rear of vehicle forward) to verify accuracy of
the line placement.
(4) Rock vehicle side-to-side three times to allow
suspension to stabilize.
(5) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(6) Measure the distance from the center of head-
lamp lens to the floor. Transfer measurement to the
alignment screen (with tape). Use this line for up/
down adjustment reference.
(7) Measure distance from the centerline of the ve-
hicle to the center of each headlamp being aligned.
Transfer measurements to screen (with tape) to each
side of vehicle centerline. Use these lines for left/
right adjustment reference.
ADJUSTMENT
(1) Remove screws and both headlamp bezels.
(2) Clean front of the headlamps.
(3) Place headlamps on LOW beam.
(4) Cover front of the headlamp that is not being
adjusted.
(5) Turn vertical adjustment screw (Fig. 2) until
the headlamp beam pattern on screen/wall is similar
to the pattern depicted in Figure 1.
When using a headlamp aiming screen:
²Adjust the headlamps so that the beam horizontal
position is at 0.
²Adjust the beam vertical position is 25 mm (1 in)
downward from the lamp horizontal centerline.
(6) Rotate the horizontal adjustment screw until
the headlamp beam pattern on the aiming screen/
wall similar to the pattern in Figure 1.
(7) Cover front of the headlamp that has been ad-
justed and adjust the other headlamp beam as in-
structed above.
(8) Install headlamp bezels. Tighten the screws se-
curely.
FOG LAMP ADJUSTMENT
Prepare an alignment screen. Refer to Alignment
Screen Preparation paragraph in this section. A prop-
erly aligned fog lamp will project a pattern on the
alignment screen 100 mm (4 in.) below the fog lamp
centerline and straight ahead (Fig. 3)
HEADLAMP BULB REPLACEMENTÐYJ
(1) Remove the screws and the headlamp bezel
(Fig. 4).
(2) Remove the screws and headlamp bulb retain-
ing ring.
(3) Disconnect the headlamp bulb wire harness
connector and remove the bulb from the bucket.
INSTALLATION
(1) Position the bulb in the bucket and connect the
wire harness connector.
(2) Position retaining ring on the headlamp bulb
and install screws.
(3) Install the headlamp bezel. Tighten the screws
securely.
FOG LAMPSÐYJ
Fog lamps are turned OFF by the circuit relay
when the high beam driving lamps are turned ON.
Fog lamps may be operated ONLY when low beam
headlamps are ON. If the headlamps are switched to
high beam, the low beam lamps and fog lamps will
turn OFF. The fog lamps will go back on when the
high beams are switched OFF.
The indicator lamp on the fog lamp switch will go:
²OFF when the high beams lamps are switched
ON.
²ON when the high beam lamps are switched OFF.
FOG LAMP BULB REPLACEMENT
CAUTION: Do not touch the bulb glass with fingers
or other oily surfaces. Reduced bulb life will result.
(1) Remove the screws that attach the stone shield
and the reflector to the lamp housing. Remove the
stone shield and reflector from the lamp housing
(Fig. 5).
(2) Remove the bulb/element holder from the lens/
reflector.
