With more passenger(s) or luggage in the vehicle, the vehicle position differs from that in such vehicle state with one
person and no load in the vehicle and angle of the headlight optical axis varies accordingly. This system automatically
adjusts the varied angle to maintain the optical axis properly.
Front and rear height sensors
Front height sensor (1) is installed to the front suspension frame (2) respectively and connected to the lower arm (4)
with the link (3). Also rear height sensor is installed to the rear floor center cross member (5) respectively and
connected to the rear axle (6) with the link (3). Each height sensor converts vertical movement of the lower arm into
the resistance value and outputs the detected change in the vehicle position as a voltage signal to the headlight
leveling control module.
Headlight leveling control module
Headlight leveling control module is installed at the inside of the glove box. It uses the headlight ON signal from the
lighting switch, vehicle speed signal from BCM and vehicle position signal from height sensors to calculate the angle
of the headlight optical axis to be corrected. Then it adjusts the optical axis angle of headlight based on the calculated
angle value by driving the headlight leveling actuator so that proper headlight aiming is obtained. Also, when any
abnormality is detected in the system, the headlight leveling control module makes the headlight leveling warning light
in the combination meter light up to warn the driver of an abnormality in the system.
Fail-safe function of headlight leveling control module
Headlight leveling control module has a fail-safe function which operates as follows.

• 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.
