ON-VEHICLE SERVICE
MAINTENANCE SERVICE
NOTE:

When having driven through water, check immediately if wa-
ter has entered (if so, oil is cloudy). Water mixed oil must be
changed at once.

Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status
of breather hoses.
CHANGING OIL
NOTE:

Hypoid gear oil must be used for differential.

It is highly recommended to use SAE 80W-90 viscosity.
1) Before oil change or inspection, be sure to stop engine and lift
up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found, cor-
rect its cause.
3) Drain old oil and pour proper amount of gear oil as specified
(roughly up to level hole).
4) Torque drain and level / filler plugs to specification.

NOTE:

Unless otherwise obligated by local regulations, adjust
headlight aiming according to following procedure.

After replacing headlight, be sure to perform its aiming.

When inspecting and adjusting headlight with leveling sys-
tem, make sure to set the leveling switch to ª0º position with
IG switch ON.
Before adjustment, make sure the following.
a) Place vehicle on a flat surface in front of blank wall as below
ahead of headlight surface.
Clearance ªaº: 10 m (32.8 ft)
b) Adjust air pressure of all tires to a specified value respectively.
c) Bounce vehicle body up and down by hand to stabilize suspen-
sion.
d) Carry out one driver aboard.
Driver's weight: 75 kg (165 lb)
Adjustment
1) Check to see if hot spot (high intensity zone) of each main (low)
beam axis falls as illustrated.
Clearance ªHº: Approx. 130 mm (5.15 in.)
2) If headlight aiming is not set properly, align it to specification by
adjusting aiming screw and aiming gear.

LEVELING SWITCH
INSPECTION
To check the switch operation, substitute it with a new one. If proper
operation is obtained, it means the switch is defective.
Replace it with a new one.
LEVELING ACTUATOR
INSPECTION
All headlight system couples connected including leveling actuator
and switch, and at Ignition switch ON, listen to the leveling actuator
sound on both actuators according to the movement of the leveling
switch. If no sound is heard with the movement of the leveling
switch, replace headlight assembly.
