shifter. In the event of a loss
of 12-volt battery power, the
electric parking brake
cannot be released, and the
vehicle cannot be shifted to
N (Neutral). Tire skates or
dollies must be used under
the non-rolling tires to
prevent damage while
loading/unloading the
vehicle. Dragging the vehicle
will cause damage not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with a tow eye. Improper use
of the tow eye may cause
damage to the vehicle and is
not covered by the vehicle
warranty. If equipped, use
the tow eye to load the

surface, or to move the
vehicle a very short distance
at a walking pace. The tow
eye is not designed for
off-road recovery. The
vehicle must be in
N (Neutral) with the electric
parking brake released when
using the tow eye.
Contact a professional towing
service if the disabled vehicle
must be transported. GM
recommends a flatbed tow
truck to transport a disabled
vehicle. Use ramps to help
reduce approach angles,
if necessary.
If equipped, a tow eye may be
located near the spare tire or
emergency jack. Do not use
the tow eye to pull the vehicle
from the snow, mud, sand,
or ditch. Tow eye threads may
have right or left-hand
threads. Use caution when
installing or removing the
tow eye. The vehicle must be in
N (Neutral) and the electric
parking brake must be
released when loading the
vehicle onto a flatbed tow
truck.
.If the vehicle is equipped
with car wash mode and has
12-volt battery power, refer
to
“Car Wash Mode” under
Automatic Transmission
0 257 to place the vehicle in
N (Neutral).
.If the 12-volt battery is dead
and/or the engine will not
start, the vehicle will not
move. Try to jump start the
vehicle. Refer to Jump
Starting - North America
0 404 and if the jump start is
successful, retry the “Car
Wash Mode” procedure.
.If jump starting is
unsuccessful, the vehicle will
not move. Tire skates or
dollies must be used under
the non-rolling tires to
prevent vehicle damage.

Front Attachment Points
The vehicle is equipped with
specific attachment points to
be used by the towing
provider. These holes may be
used to pull the vehicle from a
flat road surface onto the
flatbed tow truck.
Recreational Vehicle
Towing
Recreational vehicle towing
means towing the vehicle
behind another vehicle, such
as behind a motor home. The
two most common types ofrecreational 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:
.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. Be sure to
read the tow vehicle
manufacturer's
recommendations.
.How far the vehicle will be
towed. Some vehicles have
restrictions on how far and
how long they can be towed.
.The proper towing
equipment. See your dealer
or trailering professional foradditional advice and
equipment
recommendations.
.If 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.
Caution
Use 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.
