the infotainment system. See
"Time/Date" under Settings

Power Outlets
The accessory power outlet
can be used to plug in
electrical equipment, such as a
cell phone or MP3 player.
The vehicle has three
accessory power outlets: one
at the front of the center console, one under the
armrest, and one in the rear
cargo area.
Certain accessory power
plugs may not be compatible
with the accessory power
outlet and could overload
vehicle or adapter fuses. If a
problem is experienced, see
your dealer.
When adding electrical
equipment, be sure to follow
the proper installation
instructions included with the
equipment. See Add-On
Electrical Equipment
0325.
Caution
Hanging heavy equipment
from the power outlet can
cause damage not covered
by the vehicle warranty. The
power outlets are designed
for accessory power plugs
only, such as cell phone
charge cords. Always unplug electrical
equipment when not in use
and do not plug in equipment
that exceeds the maximum
15 amps rating.
Wireless Charging
If equipped and enabled, the
vehicle has wireless charging
in front of the center console.
The system operates at 145
kHz and wirelessly charges
one Qi compatible
smartphone. The power
output of the system is
capable of charging at a rate
up to 3 amp (15 W), as
requested by the compatible
smartphone. See Radio
Frequency Statement
0446.
{Warning
Wireless charging may
affect the operation of an
implanted pacemaker or
other medical devices. If you
have one, it is recommended

signal can be turned off
manually by moving the lever
back to its original position. If after signaling a turn or lane
change, the arrow flashes
rapidly or does not come on, a
signal bulb may be burned out.
Replace any burned out bulbs.
If a bulb is not burned out,
check the fuse. See Fuses and
Circuit Breakers

Engine Oil
To ensure proper engine
performance and long life,
careful attention must be paid
to engine oil. Following these
simple, but important steps
will help protect your
investment:
.Use engine oil approved to
the proper specification and
of the proper viscosity
grade. See “Selecting the
Right Engine Oil” in this
section.
.Check the engine oil level
regularly and maintain the
proper oil level. See
“Checking Engine Oil” and
“When to Add Engine Oil” in
this section.
.Change the engine oil at the
appropriate time. See Engine
Oil Life System 0335.
.Always dispose of engine oil
properly. See “What to Do
with Used Oil” in this section.
Checking Engine Oil
Check the engine oil level
regularly, every 650 km
(400 mi), especially prior to a
long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment
Overview0331 for the
location.
{Warning
The engine oil dipstick
handle may be hot; it could
burn you. Use a towel or
glove to touch the dipstick
handle.
If a low oil Driver Information
Center (DIC) message displays,
check the oil level.
Follow these guidelines:
.To get an accurate reading,
park the vehicle on level
ground. Check the engine oil
level after the engine has

4. Turn the bulb socketcounterclockwise and pull
the bulb straight out of the
socket.
5. Replace the bulb and reverse Steps 1–4 to
reinstall.
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.
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.
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.

16412876) - 2023 - CRC - 3/25/22
Vehicle Care 353
2. Locate the fuse puller inthe engine compartment
fuse block.3. Use the fuse puller toremove the fuse from the
top or side, as shown
above.
4. If the fuse must be replaced immediately,
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)

or others could be injured or
killed, and the vehicle could
be damaged.
See Accessories and
Modifications 0327 and
General Information 0327.
To check or replace a blown
fuse, see Electrical System
Overload 0352.
Engine Compartment
Fuse Block
The underhood fuse block is in
the engine compartment, on
the driver side of the vehicle.
Caution
Do not pull the engine
compartment fuse block
lever, since it is intended
only for service purposes.
If pulled, vehicle malfunction
may occur.
Caution
Spilling liquid on any
electrical component on the
vehicle may damage it.
Always keep the covers on
any electrical component.
