Towing the Vehicle

Transporting a Disabled Vehicle

Caution
Incorrectly transporting a disabled vehicle
may cause damage to the vehicle. Use
proper tire straps to secure the vehicle to
the flatbed tow truck. Do not strap or
hook to any frame, underbody,
or suspension component not specified
below. Do not move vehicles with drive
axle tires on the ground. Damage is not
covered by the vehicle warranty.
Caution
The vehicle may be equipped with an
electric parking brake and/or an
electronic 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.
Contact a professional towing service if the
disabled vehicle must be transported. GM
requires a flatbed tow truck or a trailer to
transport a disabled vehicle. Use ramps to
help reduce approach angles, if necessary.
Your vehicle was neither designed nor
intended to be towed with any of its wheels
on the ground. However, if the vehicle must
be towed with its wheels on the ground to
reach a safe location for loading on a
flatbed tow truck or trailer, see the
limitations below:
Your vehicle is pulled facing forward.
Your vehicle is successfully shifted to
N (Neutral).
The maximum speed of your vehicle is
20 km/h (12.4 MPH).
The maximum distance towed is 60 km
(37.3 mi).
Preparing the Vehicle:
If equipped with air suspension, before the
vehicle is loaded or secured on the flat bed,
with the vehicle ON, doors closed, and hood
closed, use the ride height buttons to open
the ride height menu. Select Entry/Exit
Height to lower the vehicle. Once the
vehicle is lowered to Entry/Exit Height,
enable "Service Mode" in the infotainment
screen under Settings>Vehicle>Suspension to
hold the suspension in the lowered position.
