WRECKER TOWING
Always unload your vehicle before towing it. The recommended method
of towing is with the drive wheels off the ground.
Before towing, make sure:
• the parking brake is released.
• if air pressure has been lost, to release the brakes manually.
Improper towing of the vehicle will not allow sufficient lubrication of the
transmission which may cause serious damage to internal transmission
components. Always follow the outlined towing procedures.
• To tow a vehicle on the front wheels, the steering wheel must be
in the straight ahead position. Secure the steering wheel with a
holding device (such as provided by a towing company).
• To tow a vehicle on the rear wheels, it will be necessary to remove
the drive axles or disconnect the driveshaft. If the drive axles are
removed, the ends of the axle housing must be sealed to prevent the
loss of axle lubricant during towing.
• To tow a vehicle with an inoperative rear axle, the rear wheels
must be raised onto a dolly or tow the vehicle on the front wheels.
• If your vehicle is equipped with tow hooks, chains must be
fastened directly to the tow hooks on the vehicle.
• If your vehicle is not equipped with tow hooks, chains must be
routed under the bottom edge of the bumper with a protection bar to
protect the bumper, and attached to the vehicle chassis. Under no
circumstances is the vehicle to be lifted or towed by attaching chains
directly to the bumper.
RAISING THE VEHICLE
Never lift the vehicle by the bumper. When raising the vehicle, attach
chains to or place the jack(s) directly beneath the main structural
members of the vehicle.
PUSH-STARTING YOUR VEHICLE
Avoid attempting to start a vehicle by pushing. Instead, use jumper
cables as described under Jump starting your vehicle in the Roadside
emergencies chapter. Vehicles with an automatic transmission cannot be
started by pushing.
