Towing
lf the vehicle needs to be towed, call a professional tow-
ing service. Never tow the vehicle behind another vehi
cle with iust a rope or chain lt 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 t\ivo 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 attemDted.
lf the vehicle cannot be transported by flat-bed. it should
be towed with the front wheels off the ground lf due to
damage, the vehicle must be towed with the front
wheels on the ground, do the following:
lvlanual Transmission and CW
. Release the parking brake
. Shift the transmission to neutral (CW to E position)'
Automatic Transmission
. Release the Parking brake.
. Sta rt the engine.
. Shift to LDll position, then E position.
. Turn oif the engine
CAUTION;
o lmploper towing preparation will damage ihe tfans-
mission. Follow the above procedute exaqtly lf you
cannot shift the tlansmission or start the engino
laulomatic transmissionl, yout vehicle must be trans-
ported on a flat-bed.
. lt is best to tow the vehicle no farther than 50 mil€s
(80 km), and ksop thE speed below 35 mph (55 km/hl
. Trying to lift 01 tow your vehicle by tho bump€F will
caus€ setious damagg. Ths bumpers are not dEigned
to supportthe vshicle's weigh.
