lift to tow the vehicle. This could
damage the vehicle.
GM recommends a flatbed tow truck
to transport a disabled vehicle. Use
ramps to help reduce approach
angles, if necessary. A towed
vehicle should have its drive wheels
off the ground. Contact Roadside
Assistance 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
dinghy 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 on a dolly.
Here are some important things to
consider before recreational vehicle
towing:
.
Before towing the vehicle,
become familiar with the local
laws that apply to recreational
vehicle towing. These laws may
vary by region.
.
The towing capacity of the
towing vehicle. Read the tow
vehicle manufacturer's
recommendations.
.
How far the vehicle can be
towed. Some vehicles have
restrictions on how far and how
long the vehicle can be towed.
.
Whether the vehicle has the
proper towing equipment. See
your dealer or trailering professional for additional advice
and equipment
recommendations.
.
Whether the vehicle is ready to
be towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Follow the tow vehicle
manufacturer ’ s instructions.
CautionUse of a shield mounted in front
of the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would
not be covered by the vehicle
warranty. If using a shield, only
use one that attaches to the
towing vehicle.
