start after a few tries, it probably
needs service.
Caution
If the jumper cables are connected
or removed in the wrong order,
electrical shorting may occur and
damage the vehicle. The repairs
would not be covered by the vehicle
warranty. Always connect and
remove the jumper cables in the
correct order, making sure that the

to idle for several minutes.
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to suspension
components. Use the proper straps
around the tires to secure the
vehicle.
Have the vehicle towed on a wheel lift
tow truck. A flatbed car carrier could
damage the vehicle. The wheel lift tow
truck must raise the rear of the
vehicle and wheel dollies must be
used to lift the front wheels off the
ground.
Consult your dealer or a professional
towing service if the disabled vehicle
must be towed.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle such as a motor home. The
two most common types of
recreational vehicle towing are known
as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle
with all four wheels on the ground.
Dolly towing is towing the vehicle
with two wheels on the ground and
two wheels up on a device known as a
dolly.
Here are some important things to
consider before recreational vehicle
towing:
. What is the towing capacity of the
towing vehicle? Be sure to read the
tow vehicle manufacturer's
recommendations.
. What is the distance that will be
traveled? Some vehicles have
restrictions on how far and how
long they can tow.
