Tow Truck Towing

INFOID:0000000001679200

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 tow-

ing 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 powertrain 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

INFINITI recommends that vehicle be towed with the driving (rear) wheels off the ground or that a dolly be
used as illustrated.

CAUTION:

• Never tow automatic transmission models with the rear wheels on the ground or four wheels on the

ground (forward or backward), as this may cause serious and expensive damage to the transmis-
sion.
If it is necessary to tow the vehicle with the front wheels raised, always use towing dollies under the
rear wheels. 

• When towing rear wheel drive models with the front wheels on the ground or on towing dollies:
- 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 secure the steering wheel by turning the ignition key to the LOCK
position. This may damage the steering lock mechanism.

- Move the selector lever to the N (Neutral) position.
• When the battery of vehicle equipped with the Intelligent Key system is discharged, your vehicle

should be towed with the front wheels on towing dollies or place the vehicle on a flat bed truck.

If the speed or distance must necessarily be greater, remove the propeller shaft before towing to prevent dam-
age to the transmission.

explode and result in serious injury. Parts of your vehicle
could also overheat and be damaged.

CAUTION:

• Tow chains or cables must be attached only to the vehicle

recovery hooks or main structural members of the vehicle.
Otherwise, the vehicle body will be damaged.

• Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow the vehi-

cle using the vehicle tie downs or recovery hooks.

• Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or

cooling systems.

• Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or

recovery.

• Rear hook is not available.

AUTOMATIC TRANSMISSION

To tow a vehicle equipped with an automatic transmission, an appropriate vehicle dolly MUST be placed under
the towed vehicle's drive wheels. Always follow the dolly manufacture's recommendations when using their
product.
If the vehicle is stuck in sand, snow, mud, etc., use the following procedure:

1.

Turn off the Vehicle Dynamic Control System.

2.

Make sure the area in front and behind the vehicle is clear of obstructions.

3.

Turn the steering wheel right and left to clear an area around the front tires.

4.

Slowly rock the vehicle forward and backward.
Shift back and forth between R (reverse) and D (drive).
Apply the accelerator as little as possible to maintain the rocking motion.
Release the accelerator pedal before shifting between R and D.
Do not spin the tires above 35 mph (55 km/h).

5.

If the vehicle can not be freed after a few tries, contact a professional towing service to remove the vehi-
cle.
