1. Hood
A: REMOVAL AND INSTALLATION
NOTE:
The hood lock has a dual locking design which
consists of a main lock and a safety lock mecha-
nism. When the release knob located at the front
pillar on the driver's side is pulled back, the main
lock is released through the cable attached to the
knob.
The safety lock can be released by pushing the
lever protruding above the front grill while opening
the hood.
1. HOOD
1) Open front hood, and remove washer hose.
2) Remove attaching bolts.

3) Detach front hood from hinges.
4) Install in the reverse order of removal.
CAUTION:
Adjust buffer assembly on each end so that
main lock is applied securely when hood is
released from a height of approx. 20 mm (0.79
in).
NOTE:
Align the center of striker with lock during installa-
tion. Make sure safety lever is properly caught by
the striker under the hood's own weight.

2. HOOD LOCK
1) Open front hood and remove front grille. to 5-1 [W12A0].>
2) Remove bolts which secure lock assembly to
radiator panel, and remove lock assembly.
