Aiming Adjustment
EKS009L3
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.
●
Keep all tires inflated to correct pressure.
●
Place vehicle on level ground.
●
See 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 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 adjustment screw access. Refer to
Installation of Front Fender Protector"
4.
Adjust front fog lamps using adjustment 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.
●
When performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

Bulb Replacement
EKS009L4
1.
Disconnect fog lamp connector.
2.
Turn the bulb counterclockwise to remove it.
CAUTION:
●
Do not 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.
●
Do not 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 Fog Lamp
EKS009L5
REMOVAL
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb.
CAUTION:
●
Do not 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.
●
Grasp 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 to
EI-21, "Removal and Installation of Front Fender Pro-
2.
Disconnect fog lamp connector.
3.
Remove fog lamp screws and pull fog lamp rearward out of front
bumper.
INSTALLATION
Installation is in the reverse order of removal.

When the remote keyless entry system is triggered by input from the keyfob, the BCM, interpreting it as turn
signal is ON, outputs turn signal from BCM terminals 60 and 61.
The BCM supplies power
●
through BCM terminals 60 and 61
●
to front turn signal lamp LH and RH terminal 1
●
through front turn signal lamp LH and RH terminal 3
●
to grounds E9, E15 and E24, and
●
