A: SPECIFICATION
B: PRECAUTIONS
 Before removing and installing parts, always disconnect the battery ground cable. When replacing audio,
control module, and other parts provided with memory functions, record memory contents before disconnect-
ing the battery ground cable. Otherwise, the memory will be erased.
 Reassemble in reverse order of disassembly, unless otherwise indicated.
 Adjust parts to the given specifications.
 Connect the connectors and hoses securely during reassembly.
 After reassembly, make sure functional parts operate smoothly.
WARNING:
 Airbag system wiring harness is routed near electrical parts and switches. All airbag system wiring
harnesses and connectors are yellow. Do not use electric test equipment on these circuits.
 Be careful not to damage the airbag system wiring harness when servicing electrical parts and
switches.

7) Remove the packing (A) from seal groove.
CAUTION:
Completely remove the packing not to leave
any chips behind.
D: ASSEMBLY
1) Cut the tip of packing (A) at an angle of 45°.
2) With the cut end facing upward, insert the pack-
ing (A) into groove around seal.
CAUTION:
 If the packing protrudes, slowly take it off the
groove.
 Do not stretch the packing. If the packing is
stretched, seal fails.
3) After making a round of the seal, cut its tip at an
angle of 45°, with its length 10 mm (0.39 in) longer
than the circumference of seal so that the tip over-
laps the other. Then, press it onto the seal, using a
screwdriver.4) Match the positions of the lens and headlight as-
sembly, and then insert the lens into headlight as-
sembly.
5) Secure the hook, and then install the clip and
screw.
6) Put the seal portion of headlight assembly into
the water and check that water does not enter in-
side the headlight.
CAUTION:
Be sure that water does not enter inside the
headlight through the bulb socket or ventilation
hole.
E: ADJUSTMENT
1. HEADLIGHT AIMING
CAUTION:
Turn off the light before adjusting headlight
aiming. If the light is necessary to check aim-
ing, do not turn on for more than two minutes.
NOTE:
Before checking the headlight aiming, be sure of
the following:
 The area around the headlight has not sustained
any accident, damage or other type of deformation.
 Vehicle is parked on a level surface.
 The inflation pressure of tires is correct.
 Vehicle’s fuel tank is fully charged.
1) Bounce the vehicle several times to normalize
the suspension.
2) Make certain that someone is seated in the driv-
er’s seat.
3) Turn the headlights on and then adjust the low
beam pattern by following positions on the screen.
NOTE:
 Set the headlight beam leveler switch to “0” posi-
tion.
 Adjust the vertical aim (A) first, then horizontal
aim (B).(A) Packing
