CAUTION:

All applicable State or Provincial (in Canada) laws and local laws regarding the towing operation

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.

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

Vehicle Recovery (Freeing a stuck vehicle)EAS001FZ

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.
