Fitting Adjustment INFOID:0000000004307410
GAP ADJUSTMENT 1. Tilt up glass lid.
2. Loosen glass lid bolts, then tilt down glass lid.
3. Adjust glass lid from outside of vehicle so it resembles “A–A” “B– B” “C–C” as shown in the figure.
• For gap adjustment "A-A" "C-C", carefully slide glass lid for- ward and rearward in vehicle.
• For gap adjustment "B-B", loosen sunroof unit assembly and
shift side to side.
NOTE:
To prevent glass lid from moving after adjustment, lightly tighten
the bolts.
4. Tighten left front bolt, then right rear bolt to prevent uneven torque. Tighten remaining bolts, being careful to prevent glass
lid from moving.
5. Tilt glass lid up and down several times to check that it moves smoothly, and retains the adjustment.

HEIGHT ADJUSTMENT
1. Tilt up glass lid.
2. Loosen glass lid bolts, then tilt down glass lid.
3. Adjust glass lid from outside of vehicle so it resembles "A-A" "B-B" "C-C" as shown in the figure.
• For height adjustment, manually raise/lower glass lid assembly until height difference is within specifica-
tions.
NOTE:
• If necessary, shims may be added between sunroof unit
assembly and roof panel to increase glass lid height adjust-
ment range.
• To prevent glass lid from moving after adjustment, lightly
tighten the bolts.
4. Tighten left front bolt, then right rear bolt to prevent uneven torque. Tighten remaining bolts, being careful to prevent glass
lid from moving.

Inspection INFOID:0000000004307411
WIND DEFLECTOR
Check that the wind deflector (1) moves freely within the sunroof unit
assembly while manually pressing down and releasing. If a malfunc-
tion is detected, remove and visually check the deflector for damage,
deteriorated components, or foreign objects within mechanism.
Check to determine if a sufficient amount of grease has been applied
to the pivot areas for non-binding operation, if not add grease as
required. If it is damaged, replace it with a new one. If no damage is
found, reinstall it properly.
⇐ : Vehicle front
LINK ASSEMBLY AND WIRE
NOTE:
Before replacing a suspect part, make sure it is the source of noise being experienced.
1. Check link to determine if coated film has peeled off to such an extent that substrate is visible. Check also
to determine if link is the source of noise. If it is, replace it.
2. Visually check to determine if a sufficient amount of grease has been applied to wire or rail groove of the
sunroof unit assembly. If not, add grease as required.
3. Check wire for any damage or deterioration. If any damage is found, replace sunroof unit assembly.
WEATHERSTRIP
1. Visually check weatherstrip for dam age, deterioration, or deformation.
• Open glass lid assembly enough to inspect front edge of weatherstrip.
• Tilt up glass lid assembly fully to in spect sides and rear edge of weatherstrip.
If any area of the weatherstrip is found to be damaged, replace the glass lid assembly. Refer to RF-22," Removal and Installation " .
2. Check for leakage around glass lid. • Close glass lid fully.
• Pour water around surface to determine area of concern.
- For gaps or misalignment, adjust glass lid to specifications. Refer to RF-27, " Fitting Adjustment " .
- For damaged sealing surfaces, either replace glass lid RF-22, " Removal and Installation " , or repair the
panel BL-307, " Precaution in Repairing High Strength Steel " .

tion measures.
Precaution INFOID:0000000004306501
• When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
• When removing parts with a screwdriver or other tool , protect parts by wrapping tools with vinyl or tape.
• Keep removed parts protected with cloth.
• If a clip is deformed or damaged, replace it.
• If an unreusable part is removed, replace it with a new one.
• Tighten bolts and nuts firmly to the specified torque.
• After re-assembly has been completed, make sure each part functions correctly.
• Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tight ly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
