Aiming AdjustmentEKS00P4D
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.
lKeep all tires inflated to correct pressure.
lPlace vehicle on level surface.
lSee 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 adjustment
screw.
NOTE:
Use a Phillips screwdriver to adjust. Turn screw clockwise to raise
pattern and counterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog
lamp lens as shown.
2. Turn front fog lamps ON.
3. Remove front portion of fender protector(s) for adjusting screw
access. Refer toEI-22, "
Removal and Installation of Front
Fender Protector".
4. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 100 mm (4 in) below the height of
the fog lamp centers as shown.
lWhen performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

Bulb Replacement
EKS00P4E
1. Disconnect front fog lamp connector.
2. Turn the bulb socket counterclockwise to remove it.
CAUTION:
lNever touch the glass of bulb directly by hand. Keep
grease and other oily substances away from it. Do not
touch bulb by hand while it is lit or right after being
turned off. Burning may result.
lNever leave bulb out of fog lamp reflector for a long time
because dust, moisture smoke, etc. may affect the perfor-
mance of fog lamp. When replacing bulb, be sure to
replace it with new one.
Removal and Installation of Front Fog LampEKS00P4F
REMOVAL
The front fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb.
CAUTION:
lNever leave fog lamp assembly without bulb for a long period of time. Dust, moisture, smoke, etc.
entering the fog lamp body may affect the performance. Remove the bulb from the headlamp
assembly just before replacement bulb is installed.
lGrasp only the plastic base when handling the bulb. Never touch the glass envelope. Touching the
glass could significantly affect the bulb life and/or fog lamp performance.
1. Remove front portion of fender protector. Refer toEI-22, "
Removal and Installation of Front Fender Pro-
tector".
2. Disconnect front fog lamp connector.
3. Remove front fog lamp screws and pull fog lamp rearward out of
front bumper.

REAR FOG LAMPPFP:26550
Component Parts and Harness Connector LocationEKS00P4G
System DescriptionEKS00P4H
The control of the rear fog lamps is dependent upon the position of the lighting switch. The lighting switch must
be in the 1ST position, 2ND position or AUTO position (LOW beam is ON) for rear fog lamp operation. When
the lighting switch is placed in the rear fog lamp position the BCM (body control module) receives input signal
requesting the rear fog lamps to illuminate.
