1999 NISSAN PRIMERA height adjustment

Assembly
Apply high-temperature grease to lubricate the bearing, gears
and frictional surface when assembling the starter.
Carefully observe the following instructions.
PINION PROTRUSION LENGTH ADJUSTMENT
Clearance“l”
With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance“l”between the front edge
of the pinion and the pinion stopper.
Clearance“l”:
Refer to SDS (EL-52).
Movement“
”
Compare movement“
”in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by hand
until it touches stopper.
Movement“
”
Refer to SDS (EL-52).

Not in the specified value ... Adjust by selecting the correct
adjusting plate.

System Description
The auto level control unit is designed to adjust the beam angle of the headlamp in response to the load-
ing conditions of the vehicle. It is not designed to compensate for the dynamic handling of the vehicle.
The vehicle’s front and rear height is measured by sensors attached to the front stabilizer bar and the rear
suspension lateral link arm. The sensors provide a signal to the auto level control unit, which calculates the
correct headlamp aiming position and sends a signal to the aiming motors.
Initialisation
After the replacement or adjustment of any suspension sensor, the system must be self calibrated. This is
achieved as follows.
The vehicle must be empty, since any load will result in an invalid calibration. From outside of the vehicle
turn ignition on and then within 7 seconds the light switch must be turned from off to side lights on position,
5 times, finishing with the lamps in the on position.
The headlamps will then move to the highest, then the lowest then the normal position to indicate that the
calibration is successful, as can be seen by the moving beam pattern.
After successful calibration the headlamps must then be aimed in the conventional manner. Refer to EL-70.

Aiming Adjustment
Before performing aiming adjustment, make sure of the follow-
ing.
a. Keep all tires inflated to correct pressure.
b. Place vehicle on level ground.
c. Check that vehicle is unloaded (except for full levels of
coolant, engine oil and fuel, and spare tire, jack, and tools).
Have the driver or equivalent weight placed in driver’s seat.
1. Set the distance between the screen and the center of the
fog lamp lens as shown at left.
2. Turn front fog lamps ON.
3. Adjust front fog lamps so that the top edge of the high inten-
sity zone is 100 mm (4 in) below the height of the fog lamp
centers as shown at left.

When performing adjustment, if necessary, cover the head-
lamps and opposite fog lamp.
