Bulb Replacement
For the proper type of
replacement bulbs, or any bulb
changing procedure not listed
in this section, contact your
dealer.
Caution
Do not replace incandescent
bulbs with aftermarket LED
replacement bulbs. This can
cause damage to the vehicle
electrical system.
LED Lighting
This vehicle has several LED
lamps. For replacement of any
LED lighting assembly, contact
your dealer.
Electrical System
High Voltage Devices
and Wiring
{Warning
Exposure to high voltage
can cause shock, burns, and
even death. The high voltage
components in the vehicle
can only be serviced by
technicians with special
training.
High voltage components
are identified by labels. Do
not remove, open, take
apart, or modify these
components. High voltage
cable or wiring has orange
covering or labels. Do not
probe, tamper with, cut,
or modify high voltage cable
or wiring.
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 the wires that provide
the power to the devices in
your vehicle.
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.

324 Vehicle Care
To check a fuse, look at the
band inside the fuse. If the
band is broken or melted,
replace the fuse. Be sure to
replace a bad fuse with a fuse
of the identical size and rating.
Replacing a Blown Fuse
1. Turn off the vehicle.
2. Locate the fuse puller in theunderhood compartment
fuse block.
3. Use the fuse puller toremove the fuse from the
top or side, as shown above.

Vehicle Care 325
4. If the fuse must be replacedimmediately, borrow a
replacement fuse with the
same amperage from the
fuse block. Choose a vehicle
feature that is not needed
to safely operate the
vehicle. Repeat Steps 2–3.
5. Insert the replacement fuse into the empty slot of the
blown fuse.
At the next opportunity, see
your dealer to replace the
blown fuse.
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 in a fire. You (Continued)
