Tow Truck TowingINFOID:0000000003531499
WARNING:
• Never get under the vehicle while it is supported only by the jack. Always use safety stands to sup-
port the frame when you have to get under the vehicle.
• Place wheel chocks at both front and back of the wheels on the ground.
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 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 powertrain are in good order. If
any unit is damaged, dollies must be used.
• Never tow an automatic transmission model from the rear
(i.e., backward) with four wheels on the ground as this may
cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:
• When towing with the front wheels on the ground: Turn the
ignition key to the OFF position and move the transmission
selector lever to N (neutral) position, turn the ignition key to
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.

INFINITI does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:
• Never tow 4WD models with any of the wheels on the ground
as this may cause serious and expensive damage to the
transfer case and transmission.
Towing Point
CAUTION:
Never tow the vehicle using only the towing points. To avoid
damaging the vehicle body, use proper towing equipment when
towing.
Vehicle Recovery (Freeing a stuck vehicle)INFOID:0000000003531500
•Tow chains or cables must be attached only to the main structural members of the vehicle or the
towing hooks (if so equipped). Otherwise, the vehicle body will be damaged.
•Use the towing hook (if so equipped) only to free a vehicle stuck in sand, snow, mud, etc. Never tow
the vehicle for a long distance using only the towing hook.
•The towing hook is under tremendous force when used to free a stuck vehicle. Never pull the hook at
an angle.
•Always pull the cable straight out from the front or rear of the vehicle.
•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.
WARNING:
• Stand clear of a stuck vehicle.
• Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.
