BODY ELECTRICAL SYSTEM
PRECAUTION
Take care to observe the following precautions when performing inspections o\
r removal and replacement
of body electrical related parts.
1. HEADLIGHT SYSTEM
Halogen bulbs have pressurized gas inside and require special handling. They ca\
n burst if scratched or
dropped. Hold a bulb only by its plastic or metal case. Don’t touch the glass\
part of a bulb with bare hands.
2. SRS (SUPPLEMENTAL RESTRAINT SYSTEM)
The LAND CRUISER is equipped with an SRS (Supplemental Restraint System) such as the driver airbag
and front passenger airbag. Failure to carry out service operation in th\
e correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (in\
-
cluding removal or installation of parts, inspection or replacement), be sure t\
o read the precautionary notices
in the RS section.
3. AUDIO SYSTEM
If the negative (−) terminal cable is disconnected from the battery, the preset AM, FM 1 and FM 2 stations
stored in memory are erased, so be sure to note the stations and reset them af\
ter the negative ( −) terminal
cable is reconnected to the battery.
4. MOBILE COMMUNICATION SYSTEM
If the vehicle is equipped with a mobile communication system, refer to \
precautions in the IN section.

BODY ELECTRICAL HEADLIGHT AND TAILLIGHT SYSTEM
1996 LAND CRUISER (RM451U)
ADJUSTMENT
1. ADJUSTING HEADLIGHT AIM ONLY
(a) Put the vehicle in below conditions.
Make sure the body around the headlight is not de-
formed.
Park the vehicle on a level place.
The driver gets into the driver’s seat and puts the
vehicle in a state ready for driving (with a full tank).
Bounce the vehicle several times.
(b) Adjust headlight in vertical alignment.
If the gauge bubble is outside the acceptable range of the beam
angle gauge, adjust it using adjusting screw A.
HINT:
The beam angle will change about 0 °11’ with one mark.

(c) Adjust headlight in horizontal alignment.
If the ”0” moves away from the mark beyond the acceptable
range, adjust the ”0” back to the mark using adjusting screw B.
HINT:
The beam angle will change about 0 °23’ with one mark.
2. REPLACING HEADLIGHT
(a) Replace the headlight.
(b) Inspect the headlight aim. Do the following before inspec-
tion.
Make sure the body around the headlight is not de-
formed.
Park the vehicle on a level spot.
The driver gets into the driver’s seat and puts the
vehicle in a state ready for driving (with a full tank).
Bounce the vehicle several times.
(c) Adjust headlight in vertical alignment (1) Using adjusting screw A, adjust the headlight aim to
within the specifications.
HINT:
The beam angle will change about 0 °11’ with one mark.
(2) Make sure the gauge bubble is within the accept- able range.
HINT:
If the gauge bubble is outside the acceptable range, check that
the vehicle is parked on a level place.
(d) Readjust the headlight aim after parking the vehicle on a level place.
(e) Adjust the headlight in horizontal alignment. (1) Using adjusting screw B, adjust the headlight aim to
within the specifications.
HINT:
The beam angle will change about 0 °23’ with one mark.
(2) Using adjusting nut C, adjust the ”0” back to the mark.
HINT:
For adjustment, pull nut C to the rear of the vehicle to free it. Af-
ter adjustment, check that the nut C is locked in.
