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.
Caution
The vehicle may be equipped
with a tow eye. Improper use
of the tow eye may cause
damage to the vehicle and is

N (Neutral) with the electric
parking brake released when
using the tow eye.

Managing the Vehicle
Damage Repair Process
In the event that the vehicle
requires damage repairs, GM
recommends that you take an
active role in its repair. If you
have a pre-determined repair
facility of choice, take the
vehicle there, or have it towed
there. Specify to the facility
that any required replacement
collision parts be original equipment parts, either new
Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be
covered by the GM vehicle
warranty.
Insurance pays the bill for the
repair, but you must live with
the repair. Depending on your
policy limits, your insurance
company may initially value the
repair using aftermarket parts.
Discuss this with the repair
professional, and insist on
Genuine GM parts. Remember,
if the vehicle is leased, you
may be obligated to have the
vehicle repaired with Genuine
GM parts, even if your
insurance coverage does not
pay the full cost.
If another party's insurance
company is paying for the
repairs, you are not obligated
to accept a repair valuation
based on that insurance
company's collision policy
repair limits, as you have no
contractual limits with that
