2006 NISSAN PATROL battery

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine com-
partment side without removing the headlamp body.
+Grasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Turn the bulb retaining ring counterclockwise until it is free from
the headlamp re¯ector, and then remove it.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
5. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp re¯ector without bulb for a long period
of time. Dust, moisture, smoke, etc. entering headlamp body
may affect the performance of the headlamp. Remove head-
lamp bulb from the headlamp re¯ector just before a replace-
ment bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should be
in good repair, calibrated and operated in accordance with respec-
tive operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires in¯ated to correct pressures.
b. Place vehicle and tester on one and same ¯at surface.
c. See that there is no-load in vehicle (coolant, engine oil
®lled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ``0'' when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

System Description
UNIFIED CONTROL METER
+Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit combined with speedometer.
+Digital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
+Odo/trip meter segment can be checked in diagnosis mode.
+Meter/gauge can be checked in diagnosis mode.
Note: Sub fuel gauge is not controlled by the control unit.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
Note: Turn ignition switch to the ``ON'' position to operate odo/trip meter.
