4. Pull the bulb (2) straight out of thesocket.
5. Push the new bulb into the socket.
6. Install the bulb socket (3) by turning clockwise into the license plate lamp
assembly.
7. Replace the license plate lamp assembly by using the two screws to secure.
Electrical System
Electrical System Overload
The vehicle has fuses and circuit breakers to
protect against an electrical system
overload.
When the current electrical load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the current load
returns to normal or the problem is fixed.
This greatly reduces the chance of circuit
overload and fire caused by electrical
problems.
Fuses and circuit breakers protect power
devices in the vehicle.
Replace a bad fuse with a new one of the
identical size and rating. If there is a problem on the road and a fuse
needs to be replaced, the same amperage
fuse can be borrowed. Choose some feature
of the vehicle that is not needed to use and
replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause the lamps
to go on and off, or in some cases to
remain off. Have the headlamp wiring
checked right away if the lamps go on and
off or remain off.
Windshield Wipers
If the wiper motor overheats due to heavy
snow or ice, the windshield wipers will stop
until the motor cools and will then restart.
Although the circuit is protected from
electrical overload, overload due to heavy
snow or ice may cause wiper linkage
damage. Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an electrical
problem and not snow or ice, be sure to get
it fixed.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit breakers.
This greatly reduces the chance of damage
caused by electrical problems.
{Danger
Fuses and circuit breakers are marked
with their ampere rating. Do not exceed
the specified amperage rating when
replacing fuses and circuit breakers. Use
of an oversized fuse or circuit breaker can
result in a vehicle fire. You and others
could be seriously injured or killed.
{Warning
Installation or use of fuses that do not
meet GM’s original fuse specifications is
dangerous. The fuses could fail, and result

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
