CAUTION:

All applicable state or Provincial (in Canada) laws and 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
towing operation. Towing is in accordance with Towing Procedure Manual at dealer.

Always attach safety chains before towing.

When towing, make sure that the transmission, steering system and power train are in good order.
If any unit is damaged, dollies must be used.

Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
2WD MODELS
NISSAN recommends that vehicle be towed with the driving (front) wheels off the ground or that a dolly be
used as illustrated.
CAUTION:

Never tow automatic transmission models with the front wheels on the ground or four wheels on
the ground (forward or backward) as this may cause serious and expensive damage to the trans-
mission.
If it is necessary to tow the vehicle with the rear wheels raised, always use towing dollies under
the front wheels.

When towing automatic transmission models with the front wheels on towing dollies:
–Turn the ignition key to the OFF position, and secure the steering wheel in a straight ahead posi-
tion with a rope or similar device.
Never secure the steering wheel by turning the ignition key to the LOCK position. This may dam-
age the steering lock mechanism.
–Move the selector lever to the N (Neutral) position.

TOW TRUCK TOWING


When towing two wheel drive automatic transmission model with the rear wheels on the ground (if
you do not use towing dollies): Always release the parking brake.
4WD MODELS
NISSAN recommends that a dolly be used as illustrated when towing 4WD models.
CAUTION:
Never tow automatic transmission 4WD models with any of the wheels on the ground as this may
cause serious and expensive damage to the drive train.
Vehicle Recovery (Freeing a Stuck Vehicle) EAS001JC

Use the recovery hooks only, not other parts of the vehicle. Oth-
erwise, the vehicle body will be damaged.

Use the recovery hook only to free a vehicle stuck in sand,
snow, mud, etc. Never tow the vehicle for a long distance using
only the recovery hook.

The recovery hook is under tremendous force when used to free
a stuck vehicle. Always pull the cable straight out from the front
or rear of the vehicle. Never pull on the hook at an angle.

Stand clear of a stuck vehicle.
WARNING:

Do not spin the tires at high speed. This could cause them
to explode and result in serious injury. Parts of the vehicle
could also overheat and be damaged.
