106 INSTRUMENTS AND CONTROLS
Caution
Leaving electrical equipment
plugged in for an extended period
of time while the ignition is in
LOCK/OFF will drain the battery.
Always unplug electrical equipment
when not in use and do not plug in
equipment that exceeds the
maximum 15 ampere rating.
Certain accessory plugs may not be
compatible with the accessory power
outlet and could overload vehicle and
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 0301.
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.
Wireless Charging
If equipped, the vehicle has wireless
charging in the storage bin under the
armrest. 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 (15W),
as requested by the compatible
smartphone. See Radio Frequency
Statement 0406.
{Warning
Wireless charging can affect the
operation of an implanted
pacemaker or other medical devices.
If you have one, it is recommended
to consult with your doctor before
using the wireless charging system.
The vehicle must be on, in ACC/
ACCESSORY, or Retained Accessory
Power (RAP) must be active. The
wireless charging feature may not
correctly indicate charging when the
vehicle is in RAP, or during Bluetooth
phone calls. See Retained Accessory
Power (RAP) 0237. The operating temperature is
−40 °C
(−40 °F) to 85 °C (185 °F) for the
charging system and 0 °C (32 °F) to
35 °C (95 °F) for the phone. A text
message may be displayed on the
radio indicating that the system is
unable to charge due to high
temperature while the charger or the
phone is above or below these
operating temperature ranges.
{Warning
Remove all objects from the
charging pocket before charging
your compatible smartphone.
Objects, such as coins, keys, rings,
paper clips, or cards, between the
smartphone and the charger will
become very hot. On the rare
occasion that the charging system
does not detect an object, and the
object gets wedged between the
smartphone and the charger,
remove the smartphone and allow
the object to cool before removing
it from the charging pocket, to
prevent burns.

Caution
Do not apply tape or hang any
objects from gas struts. Also do not
push down or pull on gas struts.
This may cause damage to the
vehicle.
See Maintenance Schedule 0380.

Headlamp Aiming
Front Headlamp Aiming
Headlamp aim has been preset and
should need no further adjustment.
If the vehicle is damaged in a crash,
the headlamp aim may be affected.
If adjustment to the headlamps is
necessary, see your dealer.
Bulb Replacement
LED Lighting
This vehicle has all LED lamps. For
replacement of any LED lighting
assembly, contact your dealer.
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 in a fire.
You or others could be injured or
killed, and the vehicle could be
damaged.
See Accessories and Modifications
0 305 and
General Information 0304.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace a
bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can be
temporarily borrowed from another
fuse location, if a fuse goes out.
Replace the fuse as soon as possible.
