Features the headlamp automatic shutdown function
to avoid battery drain when the headlamps are left
on. The main features are as follows:
•Extinguishes automatically in three minutes if the
ignition switch is turned off with the lighting switch
on.
•Extinguishes in one second if the driver's door is
opened within that 3-minute period.
•If the headlamps are turned on with the ignition
switch off, the headlamps and tail lamps will
extinguish in three minutes after the driver's door
is opened or closed.
The headlamps are controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to
respective Groups below.

HEADLAMP AIMING
M1542000900538
PRE-AIMING INSTRUCTIONS
1. Inspect for badly rusted or faulty headlamp
assemblies.
2. These conditions must be corrected before a
satisfactory adjustment can be made.
3. Inspect tyre inflation, and adjust if it is necessary.
4. If the fuel tank is not full, place a weight in luggage
room of the vehicle to simulate weight of a full
tank (0.8 kg per litre).
5. There should be no other load in the vehicle other
than driver or substituted weight of approximately
75 kg placed in driver's position.
6. Thoroughly clean the headlamp lenses.7. Place the vehicle on a level floor, perpendicular to
a flat screen 10 m away from the bulb
centre-marks on the headlamp lens.
8. Rock vehicle sideways to allow vehicle to assume
its normal position.
9. Bounce the front suspension through three (3)
oscillations by applying the body weight to hood
or bumper.
10.Four lines of adhesive tape (or equivalent
markings) are required on screen or wall:
(1) Position a vertical tape or mark so that it is
aligned with the vehicle centre line.
(2) Measure the distance from the centre-marks
on the headlamp lens to the floor. Transfer the
measurement to the screen. Horizontal tape or
mark on the screen is for reference of vertical
adjustment. Item Standard value Limit

When the front fog lamp switch is turned to ON with
the tail lamp or the headlamp on (the tail lamp switch
or the headlamp switch is ON), the fog lamp relay
turns on, and the fog lamps will illuminate.
If the tail lamps or the headlamps are turned off with
the lighting switch OFF while the fog lamps are on,
the front fog lamps turn off at the same time to
prevent unattended operation.
If the tail lamps are turned off by the headlamp
automatic shutdown function, the fog lamps turn off
at the same time. However, if the tail lamps illuminate
again, the fog lamps do not.
The front fog lamps are controlled by the Smart
Wiring System (SWS). For troubleshooting, refer to
respective Groups below.

FRONT FOG LAMP AIMING CHECKM1542001100438
After setting the vehicles to the following condition,
adjust the front fog lamp aiming.
•Check that the tyre inflation pressure is at the
value indicated on the tyre pressure labels.
•Set the vehicle to the unladen condition and park
it on a level surface.
•Have a single person (approximately 75 kg) sit in
the driver’s seat.•Run the engine at a speed of 2000 r/min to fully
charge the battery.
Turn on the front fog lamps and check that the
illumination is within the standard value range.
Standard value: Illuminates to within 40
metres
CAUTION
For the fog lamp which is not being measured,
disconnect that fog lamp’s connector if possible
so that it does not illuminate while carrying out
the adjustment. Furthermore, make sure that the
light axis does not get shifted when
re-connecting the connector.
If the value is out of the standard value, insert the
screwdriver (+) through the aiming hole on the side
under cover to adjust by turning the adjusting gear
for fog lamp aiming.
NOTE: Horizontal adjustment is not possible.
In addition, the method of checking the light axis on a
screen (simple check) is given below. Item Standard value
