Towing

If the vehicle needs to be towed, call a professional tow-

ing service. Never tow the vehicle behind another vehi-

cle with just a rope or chain. It is very dangerous.

Emergency Towing

There are three popular methods of towing a vehicle:

Flat-bed Equipment — The operator loads the vehicle on

the back of a truck. This is the best way of transporting the

vehicle.

Wheel Lift Equipment — The tow truck uses two pivoting

arms that go under the tires (front or rear) and lifts them

off the ground. The other two wheels remain on the

ground.

Sling-type Equipment — The tow truck uses metal cables

with hooks on the ends. These hooks go around parts of

the frame or suspension and the cables lift that end of

the vehicle off the ground. The vehicle's suspension and

body can be seriously damaged if this method of towing

is attempted.

If the vehicle cannot be transported by flat-bed, it should

be towed with the front wheels off the ground. If due to

damage, the vehicle must be towed with the front

wheels on the ground, do the following:

• Release the parking brake.

• Start the engine.

• Shift to position, then position.

• Turn off the engine.

CAUTION:

• Improper towing preparation will damage the trans-

mission. Follow the above procedure exactly. If you

cannot shift the transmission or start the engine, the

vehicle must be transported on a flat-bed.

• It is best to tow the vehicle no farther than 50 miles

(80 km), and keep the speed below 35 mph (55

km/h).

• Trying to lift or tow the vehicle by the bumpers will

cause serious damage. The bumpers are not

designed to support the vehicle's weight.

• Make sure jacks and safety stands are placed properly

and hoist brackets are attached to the correct positions

on the engine.

• Make sure the car will not roll off stands and fall

while you are working under it.

CAUTION:

• Use fender covers to avoid damaging painted sur-

face.

• Unplug the wiring connectors carefully while holding

the connector portion to avoid damage.

Also, be sure that they do not contact other wiring

or hoses or interfere with other parts.
