General Precautions
+Do not operate the engine for an extended period of time with-
out proper exhaust ventilation.
Keep the work area well ventilated and free of any in¯ammable
materials. Special care should be taken when handling any
in¯ammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.
+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/transmission, be careful not to lose your balance and
drop it. Also, do not allow it to strike adjacent parts, especially
the brake tubes and master cylinder.
+Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
+To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
+Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.

Harness indication
+Letter designations next to test meter probe indicate harness
(connector) wire color.
+Connector numbers in a single circle
M33indicate harness con-
nectors.
Component indication
+Connector numbers in a double circle indicate component con-
nectors.
SWITCH POSITIONS
Switches are shown in wiring diagrams as if the vehicle is in the
``normal'' condition.
A vehicle is in the ``normal'' condition when:
+ignition switch is ``OFF'',
+doors, hood and trunk lid/back door are closed,
+pedals are not depressed, and
+parking brake is released.

2-pole Lift
WARNING:
When lifting the vehicle, open the lift arms as wide as possible and ensure that the front and rear of
the vehicle are well balanced.
When setting the lift arm, do not allow the arm to contact the brake tubes and fuel lines.
Put the attachment in the slit of the lift pad to prevent the frame from
slipping.
Use suitable stands at the correct places as illustrated, to prevent
the vehicle from becoming unbalanced.

Tow Truck Towing
CAUTION:
+All applicable local laws regarding the towing operation
must be obeyed.
+It is necessary to use proper towing equipment to avoid
possible damage to the vehicle during a towing operation.
+Attach safety chains for all towing.
+When towing, make sure that the transmission, steering
system and power train are in good order. If any unit is
damaged, a dolly must be used.
+When towing with the front wheels on the ground:
Turn the ignition key to the ``OFF'' position and secure the
steering wheel in a straight-ahead position with a rope or
similar device. Never place the ignition key in the ``LOCK''
position. This will result in damage to the steering lock
mechanism.
+When towing manual transmission models with the rear
wheels on the ground:
Release the parking brake and move the gearshift lever to
neutral (``N'' position).
+For 4-wheel drive models:
Set the manual-lock free-running hubs to the free position and
2-way lock free-running hubs to the auto position. (See
``
Transfer case shifting procedures for 4-wheel drive
vehicles'' in ``Starting and driving'' section.) Move the transfer
case shift lever into the ``2H'' position and the transmission shift
lever into the neutral (``N'') position.
Do not shift the transfer lever to the ``4L'' position. This will
cause damage to the transmission.
NISSAN recommends that a dolly be used as illustrated.
If you have to tow a manual transmission model with front
wheels raised (with rear wheels on ground)
Observe the following restricted raising heights.
+Do not raise the front end over!.
