Tow Truck TowingINFOID:0000000005867507
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 an d 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 wh eels on the ground as this may
cause serious and expensive dama ge to the transmission.
2WD MODEL
NIFINTI 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 posit ion and move the transmission
selector lever to N (neutral) pos ition, 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.
• When the battery of the vehicle equipped with Intelligent Key system is discharged, the vehicle should be towed with the
front wheels on towing dollies or place the vehicle on a flat
bed truck.

• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or
cooling systems
• Always pull the cable straight out from the front or rear of the vehicle. Never pull the vehicle at a
sideways angle.
• Pulling devices such as ropes or canvas straps are not recommended for use for vehicle towing or
recovery.
