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.

Hot spot specification
Angle “b”: 0.75 ° (Specification)
Calculated distance “H”: Approx. 130 mm (5.15
in.)

Diagnosis Using Output Test Function of SUZUKI Scan Tool
SUZUKI scan tool has the output test function which can force operation of following actuators and relays of the
system controlled by BCM. When a malf unction is found in the system controlled by BCM, execute the output test
which enables easy judgment whether the malfunction is on the input side or output side of BCM. For detailed
information on operation of SUZUKI scan tool, refer to “SUZUKI Scan Tool Operator’s Manual”.
