REMOVALNJSU0031S01CAUTION:
+Before removing the rear suspension assembly, discon-
nect the ABS wheel sensor from the assembly. Failure to
do so may result in damage to the sensor wires and the
sensor becoming inoperative.
+Remove suspension assembly.
1. Disconnect brake hydraulic lines and parking brake cable at
toggle lever. (Models with drum brakes.)
+Drain brake fluid before disconnecting brake lines.
2. Disconnect parking brake cable from caliper and remove brake
caliper and rotor. (Models with disc brakes.)
Suspend caliper assembly with wire so as not to stretch
brake hose.
Be careful not to depress brake pedal, or piston will pop
out.
Make sure brake hose is not twisted.
3. Using a transmission jack, raise torsion beam a little, and
remove nuts and bolts from the trailing arm, shock absorber
assembly (lower side) and lateral link (Body side).
4. Lower transmission jack, and remove suspension.
5. Remove strut securing nuts (upper side). Then pull out strut
assembly.

INSTALLATIONNJSU0031S02+Install suspension assembly.
CAUTION:
Refill with new brake fluid ªDOT 4º.
Never reuse drained brake fluid.
1. Attach torsion beam, at trailing arm and lateral link, to vehicle.
Do not tighten bolts at this time.
SRA698A
2. Using a transmission jack, place lateral link and control rod
horizontally against torsion beam. Tighten lateral link on
vehicle.
3. Attach shock absorber assembly to vehicle. Then tighten the
lower side of shock absorber assembly.
4. Lower torsion beam to fully extended position. Remove trans-
mission jack and tighten torsion beam, at trailing arm, to speci-
fied torque. Refer to SU-20.
5. Install brake hydraulic lines and tighten flare nuts.

Bulb ReplacementNJEL0015The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine com-
partment side without removing the headlamp body.
+Grasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Pull off the rubber cap.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the bulb retaining ring.
5. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
6. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long period
of time. Dust, moisture, smoke, etc. entering headlamp body
may affect the performance of the headlamp. Remove head-
lamp bulb from the headlamp reflector just before a replace-
ment bulb is installed.
Aiming AdjustmentNJEL0016For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1) Keep all tires inflated to correct pressures.
2) Place vehicle on flat surface.
3) See that there is no-load in vehicle (coolant, engine oil filled up
to correct level and full fuel tank) other than the driver (or
equivalent weight placed in driver's position).
SEL984W
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

LOW BEAM=NJEL0016S021. Turn headlamp low beam on.
2. Use adjusting screws to perform aiming adjustment.
+First tighten the adjusting screw all the way and then
make adjustment by loosening the screw.

+Adjust headlamps so that main axis of light is parallel to
center line of body and is aligned with point P shown in
illustration.
+Figure to the left shows headlamp aiming pattern for driv-
ing on right side of road; for driving on left side of road,
aiming pattern is reversed.
+Dotted lines to point P in illustration show center of head-
lamp.

System DescriptionNJEL0351The headlamp system on vehicles for North Europe contains a daytime light unit. The unit activates the fol-
lowing whenever the engine is running with the lighting switch in the OFF position:
+Low beam headlamps
+Parking, license, tail and illumination lamps
Power is supplied at all times
+through 10A fuse (No. 38, located in the fusible link and fuse box)
+to daytime light unit terminal 1 and
+to lighting switch terminal 11.
Power is also supplied at all times
+through 15A fuse (No. 39, located in the fusible link and fuse box)
+to daytime light unit terminal 3 and
+to lighting switch terminal 5.
Power is also supplied at all times
+through 15A fuse (No. 40, located in the fusible link and fuse box)
+to daytime light unit terminal 2 and
+to lighting switch terminal 8.
With the ignition switch in the ON or START position, power is supplied
+through 10A fuse [No. 20, located in the fuse block (J/B)]
+to daytime light unit terminal 7.
With the ignition switch in the START position, power is supplied
+through 10A fuse [No. 21, located in the fuse block (J/B)]
+to daytime light unit terminal 6.
Ground is supplied to daytime light unit terminal 9 through body grounds E30 and E73.
HEADLAMP OPERATION (DAYTIME LIGHT CANCEL OPERATION)NJEL0351S01When the lighting switch is turned to the 1st or 2nd position, power is supplied
+through lighting switch terminal 12,
+to daytime light unit terminal 11.
Then daytime light will be canceled. And the lighting system operation will be the same as no daytime light
system.
DAYTIME LIGHT OPERATIONNJEL0351S02With the engine running and the lighting switch in the OFF position, power is supplied
+from alternator terminal 3
+to daytime light unit terminal 8,
+through daytime light unit terminal 5
+to terminal 3 of headlamp LH,
+through daytime light unit terminal 4
+to terminal 3 of headlamp RH and
+through daytime light unit terminal 10
+to tail lamp and illumination.
Ground is supplied to terminal 2 of each headlamp through body grounds E30 and E73.
