1. Loosen lock nut and adjust pedal free height by turning brake
booster input rod. Then tighten lock nut.
Make sure that tip of input rod stays inside.
2. Adjust clearance ªC
1º and ªC2º with stop lamp switch and
ASCD switch respectively. Then tighten lock nuts.
3. Check pedal free play.
Make sure that stop lamp is off when pedal is released.
4. Check brake pedal's depressed height while engine is running.
If depressed height is below specified value, check brake sys-
tem for leaks, accumulation of air or any damage to compo-
nents (master cylinder, wheel cylinder, etc.). Then make nec-
essary repairs.

Installation=NBBR0027CAUTION:
IBe careful not to deform or bend brake pipes during instal-
lation of booster.
IReplace clevis pin if damaged.
IRefill with new brake fluid ªDOT 3º.
INever reuse drained brake fluid.
ITake care not to damage brake booster mounting bolt
thread when installing. Due to the narrow angle of
installation, the threads can be damaged by the dash
panel.
1. Before fitting booster, temporarily adjust clevis to dimension
shown.
2. Fit booster, then secure mounting nuts (brake pedal bracket to
brake booster) lightly.
3. Connect brake pedal and booster input rod with clevis pin.
4. Secure mounting nuts.
Specification: 13 - 16 N´m (1.3 - 1.6 kg-m,9-12ft-lb)
5. Install master cylinder. Refer to ªInstallationº in ªMASTER
CYLINDERº, BR-18.
6. Adjust brake pedal height and free play. Refer to ªAdjustmentº
in ªBRAKE PEDAL AND BRACKETº, BR-14.
7. Secure lock nut for clevis.
: 16 - 22 N´m (1.6 - 2.2 kg-m, 12 - 16 ft-lb)
8. Bleed air. Refer to ªBleeding Brake Systemº, BR-8.

If any gap or height difference between glass lid and roof is found,
check glass lid fit and adjust as follows:
Gap AdjustmentNBBT0018S03011. Open shade assembly.
2. Tilt glass lid up then remove side trim.
3. Loosen glass lid securing nuts (3 each on left and right sides),
then tilt glass lid down.
4. Adjust glass lid from outside of vehicle so it resembles ªA-Aº
as shown in the figure above.
5. Tilt glass lid up and down until it is adjusted to ªB-Bº as shown
in the figure above.
6. After adjusting glass lid, tilt glass lid up and tighten nuts.
7. Tilt glass lid up and down several times to check that it moves
smoothly.
Height Difference AdjustmentNBBT0018S03021. Tilt glass lid up and down.
2. Check height difference between roof panel and glass lid to
see if it is as ªA-Aº as shown in the figure above.
3. If necessary, adjust it by using one of following procedures.
IAdjust by adding or removing adjustment shim(s) between
glass lid and link assembly.
IIf glass lid protrudes above roof panel, add shim(s) or plain
washer(s) at sunroof mounting bracket or stud bolt locations to
adjust sunroof installation as required.

Aiming AdjustmentNBEL0029Before performing aiming adjustment, make sure of the following.
1) Keep all tires inflated to correct pressure.
2) Place vehicle on level ground.
3) See that vehicle is unloaded (except for full levels of coolant,
engine oil and fuel, and spare tire, jack, and tools). Have the
driver or equivalent weight placed in driver's seat.
Adjust aiming in the vertical direction by turning the adjusting
screw.

1. Set the distance between the screen and the center of the fog
lamp lens as shown at left.
2. Turn front fog lamps ON.
MEL328GA
3. Adjust front fog lamps so that the top edge of the high inten-
sity zone is 200 mm (7.9 in) below the height of the fog lamp
centers as shown at left.
IWhen performing adjustment, if necessary, cover the head-
lamps and opposite fog lamp.
