To replace a headlamp bulb, do the following:
1. Open the hood of the vehicle. See Hood Release
on page 5-9 for more information.
2. Pry up the eight fastener plugs on the radiator
cover and pull the fasteners out.
3. Lift off the radiator cover.
4. Pull the top left or right corner of the grill out so the
clips release. This will give you the needed
clearance for removing the headlamp assembly.
