HOOD
CLEARANCE AND SURFACE HEIGHT ADJUSTMENT
1. Remove the front grille. Refer to
EXT-17, "Removal and Installation".
2. Remove the hood lock assembly and adjust the height by rotating the bumper rubber until the hood clear- ance of hood and fender becomes 1 mm (0.04 in) lower than fitting standard dimension.
3. Temporarily tighten the hood lock, and position it by engaging it with the hood striker. Check the lock and striker for looseness, and tighten the lock mounting bolt to the specified torque.
4. Adjust the clearance and surface height of hood and fender according to \
the fitting standard dimension by rotating right and left bumper rubbers.
CAUTION:
Adjust right/left gap between hood and each part to the following specification.
5. Install the front grille. Refer to EXT-17, "
Removal and Installation".
HOOD LOCK ADJUSTMENT
1. Remove the front grille. Refer to EXT-17, "Removal and Installation".
2. Move the hood lock to the left or right so that striker center is vertically aligned with hood lock center (when viewed from vehicle front).
3. Make sure the secondary latch is properly engaged with the sec- ondary striker with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height or by pressing it lightly approx.
3 kg (29 N, 7lb).
CAUTION:
Do not drop the hood from 300 mm (11.81 in) height or
higher.
4. After adjusting hood lock, tighten the lock bolts.
5. Install the front grille. Refer to EXT-17, "
Removal and Installa-
tion".
Removal and Installation of Hood AssemblyINFOID:0000000005147051
