recovery. The vehicle must be in
N (Neutral) with the electric parking
brake released when using the tow eye.

Customer Information
Customer Satisfaction Procedure
Your satisfaction and goodwill are important
to your dealer and to Chevrolet. Normally,
any concerns with the sales transaction or
the operation of the vehicle will be resolved
by your dealer's sales or service
departments. Sometimes, however, despite
the best intentions of all concerned,
misunderstandings can occur. If your concern
has not been resolved to your satisfaction,
the following steps should be taken:
STEP ONE : Discuss your concern with a
member of dealership management.
Normally, concerns can be quickly resolved
at that level. If the matter has already been
reviewed with the sales, service, or parts
manager, contact the owner of your
dealership or the general manager.
STEP TWO : If after contacting a member of
dealership management, it appears your
concern cannot be resolved by your
dealership without further help, in the U.S.,
call the Chevrolet Customer Assistance
Center at 1-800-222-1020. In Canada, call
General Motors of Canada Customer Care
Centre at 1-800-263-3777 (English),
or 1-800-263-7854 (French). We encourage you to call the toll-free
number in order to give your inquiry
prompt attention. Have the following
information available to give the Customer
Assistance representative:
.Vehicle Identification Number (VIN). This is
available from the vehicle registration or
title, or the plate at the top left of the
instrument panel and visible through the
windshield.
.Dealership name and location.
.Vehicle delivery date and present mileage.
When contacting Chevrolet, remember that
your concern will likely be resolved at a
dealer's facility. That is why we suggest
following Step One first.
STEP THREE —U.S. Owners : Both General
Motors and your dealer are committed to
making sure you are completely satisfied
with your new vehicle. However, if you
continue to remain unsatisfied after
following the procedure outlined in
Steps One and Two, you can file with the
Better Business Bureau (BBB) AUTO LINE
Program to enforce your rights.
The BBB AUTO LINE Program is an
out-of-court program administered by BBB
National Programs, Inc. to settle automotive

North America and Chevrolet reserve the
right to make any changes or discontinue
the Roadside Assistance program at any
time without notification.

will tow the vehicle to the nearest
charging station or to the customer’s
home, whichever is closest.
.Flat Tire Change: If the tire has been
separated from the wheel, has damaged
sidewalls, or has a large puncture, the tire
is too severely damaged for the self
sealing tire to be effective and the vehicle
will have to be towed. It is the owner's
responsibility for the repair or
replacement of the tire if it is not covered
by the warranty.
.Battery Jump Start: Service to jump start
a dead battery.

operated, such as rate of energy
consumption or average speed. These
modules may retain personal preferences,
such as radio presets, seat positions, and
temperature settings.
