•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.
