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
0 266 to place the vehicle in
N (Neutral).
.If the 12-volt battery is dead

move. Try to jump start the
vehicle. Refer to Jump
Starting - North America
0 434 and if the jump start is
successful, retry the “Car
Wash Mode” procedure.
.If jump starting is
unsuccessful, the vehicle will

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 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:
.Become familiar with the
local laws that apply to
recreational vehicle towing.
These laws may vary by
region.
