Aiming AdjustmentNLEL0016For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1) Keep all tires inflated to correct pressures.
2) Place vehicle on flat surface.
3) See that there is no-load in vehicle (coolant, engine oil filled 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 ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

LOW BEAMNLEL0016S021. Turn headlamp low beam on.
2. Use adjusting screws to perform aiming adjustment.
+First tighten the adjusting screw all the way and then
make adjustment by loosening the screw.

+Adjust headlamps so that main axis of light is parallel to
center line of body and is aligned with point P shown in
illustration.

ing on right side of road; for driving on left side of road,
aiming pattern is reversed.

Aiming Adjustment=NLEL0029Before performing aiming adjustment, make sure of the following.
1) Keep all tires inflated to correct pressure.
2) Place vehicle on level ground.
3) See 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.
Adjust aiming in the vertical direction by turning the adjusting
screw.

1. Set the distance between the screen and the center of the fog
lamp lens as shown at left.
2. Remove front fog lamp rim. For detail, refer to ªBODY ENDº in
BT section.
3. Turn front fog lamps ON.
NEL716
4. Adjust front fog lamps so that the top edge of the high inten-
sity zone is 91 to 136 mm (3.58 to 5.35 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.

The security indicator is located on the instrument panel. The indi-
cator blinks when the ignition switch is in“OFF”or“ACC”position.
Therefore, NATS warns outsiders that the vehicle is equipped with
the anti-theft system.
+When NATS detects trouble, the security indicator lamp lights
up while ignition switch is in“ON”position.
This lighting up indicates that the anti-theft is not functioning,
so prompt service is required.
+When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs),
CONSULT-II hardware and CONSULT-II NATS software is
necessary.
Regarding the procedures of NATS initialization and NATS
ignition key ID registration, refer to CONSULT-II operation
manual, NATS.
Therefore, CONSULT-II NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.
+When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs), it
may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A
maximum of five key IDs can be registered into NATS.
+When failing to start the engine first time using the key of
NATS, start as follows.
a) Leave the ignition key in“ON”position for approximately 5
seconds.
b) Turn ignition key to“OFF”or“LOCK”position and wait approxi-
mately 5 seconds.
c) Repeat step 1 and 2 again.
d) Restart the engine while keeping the key separate from any
others on key-chain.

GENERAL PRECAUTIONSNLGI0001S03+Do not operate the engine for an extended period of time
without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refrig-
erant gas, etc. When working in a pit or other enclosed area,
be sure to properly ventilate the area before working with haz-
ardous materials.
Do not smoke while working on the vehicle.
SGI231
+Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before work-
ing on the vehicle.
These operations should be done on a level surface.
+When removing a heavy component such as the engine or
transaxle, be careful not to lose your balance and drop them.
Also, do not allow them to strike adjacent parts, especially the
brake tubes and master cylinder.

DETECTABLE LINES AND NON-DETECTABLE LINESNLGI0003S0205In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
+A line with regular weight (wider line) represents a“detectable
line for DTC (Diagnostic Trouble Code)”.A“detectable line for
DTC”is a circuit in which ECM can detect its malfunctions with
the on board diagnostic system.
+A line with less weight (thinner line) represents a“non-detect-
able line for DTC”.A“non-detectable line for DTC”is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.

SERVICE COUPLERSNLHA0117S06Never attempt to connect HFC-134a (R-134a) service couplers to
an CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers
will not properly connect to the CFC-12 (R-12) system. However, if
an improper connection is attempted, discharging and contamina-
tion may occur.

REFRIGERANT WEIGHT SCALENLHA0117S07Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2″-16
ACME.
CALIBRATING ACR4 WEIGHT SCALENLHA0117S09Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:
1. PressShift/ResetandEnterat the same time.
2. Press8787.“A1”will be displayed.
3. Remove all weight from the scale.
4. Press0, then pressEnter.“0.00”will be displayed and change
to“A2”.
5. Place a known weight (dumbbell or similar weight), between
4.5 and 36.3 kg (10 and 80 lb) on the center of the weight
scale.
6. Enter the known weight using four digits. (Example 10 lb =
“10.00”, 10.5 lb =“10.50”)
7. PressEnter—the display returns to the vacuum mode.
8. PressShift/ResetandEnterat the same time.
9. Press6—the known weight on the scale is displayed.
10. Remove the known weight from the scale.“0.00”will be dis-
played.
11. PressShift/Resetto return the ACR4 to the program mode.
CHARGING CYLINDERNLHA0117S08Using a charging cylinder is not recommended. Refrigerant may be
vented into air from cylinder’s top valve when filling the cylinder
with refrigerant. Also, the accuracy of the cylinder is generally less
than that of an electronic scale or of quality recycle/recharge
equipment.
