Instruments and Controls 121
The vehicle may have accessory
power outlets:
.Below the climate controls.
. In the cargo area, if equipped.
Open the protective cover to use the
power outlet.
The outlet is powered when the
ignition is on or in ACC/
ACCESSORY, or until the driver
door is opened within 10 minutes of
turning off the vehicle. See Retained
Accessory Power (RAP) 0191.
Certain electrical accessories may
not be compatible with the
accessory power outlet and could
overload vehicle or adapter fuses.
If there is a problem, see your
dealer.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. See Add-On Electrical
Equipment 0238.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
The vehicle may have a wireless
charging pocket outside the armrest
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 1 amp (5W), as
requested by the compatible
smartphone. See Radio Frequency
Statement 0356.
To check for smartphone
compatibility:
. In the U.S., see
www.my.buick.com/learn. .
In Canada, see
www.gmtotalconnect.ca.
. Or, see your dealer for details.
{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 or 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.
See Retained Accessory Power
(RAP) 0191.
The operating temperature is −20 °C
(−4 °F) to 60 °C (140 °F) for the
charging system and 0 °C (32 °F) to
35 °C (95 °F) for the compatible
smartphone.

Hazard Warning Flashers
|:Press to make the front and
rear turn signal lamps flash on and
off. Press again to turn the
flashers off.
The hazard warning flashers turn on
automatically if the airbags deploy.
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn.
An arrow on the instrument cluster
flashes in the direction of the turn or
lane change.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane-change 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
might be burned out.
Have any burned out bulbs
replaced. If the bulb is not burned
out, check the fuse. See
Fuses and
Circuit Breakers 0268.
Fog Lamps
The fog lamps button is on the
instrument panel to left of the
steering wheel.
To turn on the fog lamps, the ignition
and the headlamps or parking lamps
must be on.

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 0249.
. 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 Overview
0244 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 been off for at
least two hours. Checking the
engine oil level on steep grades
or too soon after engine shutoff
can result in incorrect readings.
Accuracy improves when

2. Remove the rear cargo areatrim panel push pin.
3. Pull the rear cargo area trim panel back to gain access to
the taillamp assembly.4. Remove the two nuts thatsecure the taillamp assembly.
5. Remove the taillamp assembly and disconnect the wiring
harness connector.
6. Turn the bulb socket counterclockwise to remove it.
7. Pull the bulb from the socket.
8. Install a new bulb.
9. Turn the bulb socket clockwise to install it.
10. Reverse Steps 2–4 to reinstall the taillamp assembly.
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.

268 Vehicle Care
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.
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.
To identify and check fuses, circuit
breakers, and relays, see
Engine
Compartment Fuse Block 0268 and
Instrument Panel Fuse Block 0272.
Engine Compartment

To remove the fuse block cover,
squeeze the three retaining clips on
the cover and lift it straight up.
