DESCRIPTION AND OPERATION
HEADLAMP ALIGNMENT
Headlamps and Fog Lamps should be aligned
using the screen method which is provided in this
section.The preferred headlamp alignment set-
ting is 0 for the left/right adjustment and 0 for
the up/down adjustment.
SERVICE PROCEDURES
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Inspect and correct damaged or defective com-
ponents that could interfere with 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 ADJUSTMENT USING ALIGNMENT
SCREEN
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.
(2) If necessary, tape a line on the floor 7.62
meters (25 ft.) away from and parallel to the wall
(Fig. 1).(3) From the floor up 1.27 meters (5 ft.), tape a
line on the wall at the center line of the vehicle.
Sight along the center line 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) A small dot is molded into each headlamp lens
signifying the center of the headlamp. Measure the
distance from the center of the headlamp to the floor.
Transfer measurement to the alignment screen (with
tape). Use this line for up/down adjustment refer-
ence.
(7) Measure distance from the center line of the
vehicle to the center of each headlamp being aligned.
Transfer measurements to screen (with tape) to each
side of vehicle center line. Use these lines for left/
right adjustment reference.
HEADLAMP ADJUSTMENT
The PL headlamp low beam pattern has a distinct
horizontal cutoff line which is used to visually align
the headlamps. A properly aimed headlamp will have
the horizontal cutoff line of the low beam pattern
centered on the low beam pattern centered on the
horizontal center of headlamp line. The side to side
left edge of the low beam hot spot should be located
75 mm (3 inches) to the left of the headlamp center
line (Fig. 1). The high beams on a vehicle with aero
headlamps cannot be aligned. The high beam pattern
should be correct when the low beams are aligned
properly.
To adjust headlamp alignment, rotate alignment
screws to achieve the specified low beam hot spot
pattern.

HEADLAMP ADJUSTMENT USING
ALIGNMENT SCREEN....................2
DESCRIPTION AND OPERATION
HEADLAMP ALIGNMENT
Headlamps can be aligned using the screen method
provided in this section. This method will require the
vehicle to be parked on a flat, level surface with a
minimum of 15 meters of working room in front of a
flat, level perpendicular wall or aiming.
Each headlamp has a focal point circle molded on
the lens directly in front of each headlamp bulb.
These focal point circles are used to set up lines on a
wall, or aiming board for visually aiming the head-
lamps.
The driving (high) beam location does not require
adjustment. It will be correct when the passing (low)
beam headlamps are aimed correctly.
SERVICE PROCEDURES
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Inspect and correct damaged or defective com-
ponents that could interfere with proper headlamp
alignment.
(3) Verify that the headlamp leveling switch is in
the ª0º position.
(4) Verify proper tire inflation.
(5) Clean the headlamp lenses.
(6) Verify that the luggage area is not heavily
loaded.
(7) 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.
ADJUSTMENTS
HEADLAMP ADJUSTMENT USING ALIGNMENT
SCREEN
ALIGNMENT SCREEN PREPARATION
(1) Position the vehicle on a level surface 10
meters in front of a level, flat wall or aiming board.
(2) Tape a vertical line on the wall extending 1
meter up from the floor, making sure this line is even
with the centerline of the vehicle (Fig. 1).
(3) Measure the cross-car distance between the
two headlamp focal point circles (1174mm). Transfer
half of this distance (587mm) to the left of the vehicle
centerline and tape another vertical line up from the
floor 1 meter (Fig. 1). Repeat for the right side of the
centerline.
(4) Measure the distance from the floor to the focal
point circle on the headlamp lens (635mm, but may
vary due to variations in tire size and vehicle suspen-
sion height). Transfer this measurement to the wall
and tape a horizontal line extending approximately 1
meter beyond each vertical focal point line (Fig. 1).
(5) Use these lines for left and right adjustment
reference.
HEADLAMP ADJUSTMENT
Horizontal Adjustment
The horizontal position of the passing (low) beam
pattern is adjusted by turning the T-15 Torx screw.
Located through the slot in the upper-crossmember
between the two attaching straps of the headlamp.
Vertical Adjustment
The vertical position of the passing (low) beam pat-
tern is adjusted by turning the Phillips screw on top
of the headlamp leveling motor. Located between the
headlamp housing and the upper-crossmember, just
inboard of the fender.
Adjust the passing (low) beam headlamp pat-
terns to the locations shown in the chart pro-
vided (Fig. 1).
