Headlight Bulb ReplacementS7RS0B9206002
WARNING!
• To avoid danger of being burned, don’t touch when the bulb is hot.
• Don’t touch glass surface of bulb, to avoid deteriorate as the case may be unclear
when bulb light on at dirty condition.

1) Disconnect negative (–) cable at battery.
2) Disconnect coupler from bulb.
3) Remove socket cover (1).
4) Replace bulb (2) and assemble all removed parts.
Headlight Aiming Adjustment with ScreenS7RS0B9206003
NOTE
• Unless otherwise obligated by local regulations, adjust headlight aiming
according to the following procedure.
• After replacing headlight housing, be sure to adjust aiming.
• When inspecting and adjusting headlight with leveling system, make sure to set the
leveling switch to “0 ” position with ignition
switch turned ON.

1) Make sure the following items.
• Place vehicle on a flat surface in front of blank wall (screen) (1) ahead of headlight surface.
Distance “a”
10 m (32.8 ft.)
• Adjust air pressure of all tires to the specified value respectively.
• Bounce vehicle body up and down by hand to stabilize suspension.
• Carry out aiming with a driver aboard.
Driver’s weight
75 kg (165 lb)
2) Check to see if hot spot (high intensity zone) of each low beam axis falls as shown in figure.
NOTE
If the headlights interfere each other and
make it hard to see the cut line clearly, cover
the headlight on one side. This helps to make
aiming adjustment easier.

Removal1) Disconnect negative (–) cable at battery.
2) Remove front bumper, and then remove front bumper guard from front bumper referring to “Front
Bumper and Rear Bumper Components in Section
9K”.
3) Disconnect coupler from fog light.
4) Remove fog light screws (1), and remove front fog light (2).
Installation
Reverse removal procedure for installation nothing the
following:
• After installing, adjust aimi ng referring to “Front Fog
Light Aiming Adjustment with Screen (If Equipped)”.
Front Fog Light Bulb Replacement (If Equipped)S7RS0B9206015
WARNING!
• To avoid danger of being burned, don’t touch when the bulb is hot.
• Don’t touch glass surface of bulb to avoid deteriorate as the case may be unclear
when bulb light on at dirty condition.

1) Remove front bumper referring to “Front Bumper and Rear Bumper Components in Section 9K”.
2) Remove fog light bulb (1) as shown.
3) Replace fog light bulb and assemble all removed parts.
Front Fog Light Switch Inspection (If Equipped)S7RS0B9206016
NOTE
Front fog lights light up only when headlight
switch is in HEADLIGHT position (low or high
beams) or SMALL position. Front fog lights
turn OFF automatically when headlight
switch is turned to OFF position. If front fog
light switch holds ON position, front fog
lights turn ON automa tically when headlight
switch is tuned to HEADLIGHT position (low
or high beams) or SMALL position again.

Check for continuity between terminals at each switch
position. If check result is not as specified, replace
switch.
Front Fog Light Relay Inspection (If Equipped)S7RS0B9206017
1) Check that there is no continuity between terminals “3” and “4”. If there is continuity, replace relay.
2) Connect battery positive (+ ) terminal to terminal “2”
of relay.
3) Connect battery negative (–) terminal to terminal “1” of relay.
4) Check continuity between terminals “3” and “4”. If there is no continuity when relay is connected to the
battery, replace relay.

Basic Aiming
NOTE
• Unless otherwise obligated by local regulations, adjust front fog light aiming
according to the following procedure.
• An example in case that the light-to-wall distance 10 m is shown in the illustration.
The beam descending distance “H” is
calculated when “a” is 10 m with the
specification angle “b” (1.14 °).

1) Make sure the following items.
• Place vehicle on a flat surface in front of blank wall (screen) (1) ahead of front fog light surface.
Distance between screen and front fog light
“a”: 10 m (32.8 ft.)
• Adjust air pressure of all tires to the specified value respectively.
• Bounce vehicle body up and down by hand to stabilize suspension.
• Carry out aiming with a driver aboard.
Driver’s weight

2) Check to see if hot spot (h igh intensity zone) of each
front fog light axis falls as shown in the figure.
NOTE
If the fog lights interfere each other and make

Precautions
Precautions in Diagnosing Troubles for Combination MeterS7RS0B9300001
Combination meter uses signals (information) from each control module by CAN communication to control
speedometer, tachometer, engine coolant temp meter, warning light and indicator light (other than air bag warning
light, high beam indicator light, EPS warn ing light and turn signal indicator light). Therefore, check that no DTC is
detected in each module before performing combination me ter symptom diagnosis. If any DTC is detected, correct
trouble indicated by that DTC troubleshooting first.
