WARNING:
ISituate vehicle on a flat and solid surface.
IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled down.
IFor safety during subsequent steps, the tension of wires
should be slackened against the engine.
IBefore removing front axle from transaxle, place safety
stands under designated front supporting points. Refer to
GI section for lifting points and towing.
IBe sure to hoist engine and transaxle in a safe manner.
IFor engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG
or Eurofast.
CAUTION:
IWhen lifting engine, be careful not to strike adjacent parts,
especially accelerator wire casing, brake lines, and brake
master cylinder.
IAlways use engine slingers when hoisting the engine.
IWhen removing drive shaft, be careful not to damage tran-
saxle oil seal.
1. Remove engine undercovers and splash covers.
2. Remove front exhaust tube.
3. Disconnect lower water hose from radiator and drain coolant.
4. Drain transaxle oil.
5. Remove power steering mounting bolt. (See left.)
6. Drain coolant from cylinder head.
7. Disconnect water hoses and electrical wiring from radiator and
remove radiator.
8. Disconnect fuel tubes and vacuum tubes.
9. Release power steering belt adjusting nut and remove power
steering pump from engine.
Bind pump properly to the vehicle.
10. Remove A/C compressor.
11. Disconnect or remove electrical wiring where necessary.
12. Release clutch lever cable.
13. Release tachometer cable from transaxle housing.
14. Remove front wheels.
15. Remove brake caliper mounting bolts and bind caliper properly

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.
NGI022 Note:
Lift-up points are
the same as panto-
graph jack points.
SillLift padPut the sill in the groove of the lift pad to prevent the
sill from deforming. If the pad does not have a groove,
prepare a suitable attachment with one.

Tow Truck Towing
CAUTION:
lAll applicable local laws regarding the towing operation
must be obeyed.
lIt is necessary to use proper towing equipment to avoid
possible damage to the vehicle during towing operation.
Towing is in accordance with Towing Procedure Manual
at dealer.
lWhen towing with the rear wheels on the ground, release
the parking brake and move the gearshift lever to neu-
tral position.
NISSAN recommends that vehicle be towed with the driving
(front) wheels off the ground as illustrated.
TOWING A H×CVT MODEL WITH FOUR WHEELS ON
GROUND
Observe the following restricted towing speeds and distances.
Speed:
Below 50 km/h (30 mph)
Distance:
Less than 65 km (40 miles)
CAUTION:
Never tow a H×CVT model from the rear (i.e., backward) with
four wheels on the ground as this may cause serious and
expensive damage to the transaxle.
TOWING A H×CVT MODEL WITH REAR WHEELS
RAISED (With front wheels on ground)
Never tow a H×CVT model with rear wheels raised (with front
wheels on ground) as this may cause serious and expensive
damage to the transaxle. If it is necessary to tow it with rear
wheels raised, always use a towing dolly under the front wheels.
TOWING POINT
Always pull the cable straight out from the vehicle. Never
pull on the hook at a sideways angle.
CAUTION:
Remove the front spoiler when towing the vehicle forward.
Otherwise, the towing device may damage the front spoiler.
