DRIVING AND OPERATING 295
three times, on the right or left,
depending on the lane departure
direction.
Take Steering
The LKA system does not
continuously steer the vehicle. If LKA
does not detect active driver steering,
an alert and chime may be provided.
Steer the vehicle to dismiss. LKA may
become temporarily unavailable after
repeated take steering alerts.
When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
.Sudden lighting changes, such as
when driving through tunnels.
.Banked roads.
.Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the windshield
may help. A camera blocked message may
display if the camera is blocked. Some
driver assistance systems may have
reduced performance or not work at
all. An LKA or LDW unavailable
message may display if the systems
are temporarily unavailable. This
message could be due to a blocked
camera. The LKA system does not
need service. Clean the outside of the
windshield behind the rearview mirror.
LKA assistance and/or LDW alerts
may occur due to tar marks, shadows,
cracks in the road, temporary or
construction lane markings, or other
road imperfections. This is normal
system operation; the vehicle does not
need service. Turn LKA off if these
conditions continue.
Surround Vision Recorder
If equipped, this system records the
360° camera views to an SD card. Only
images are recorded, no sound. An SD
card will be needed for this system.
The recommended SD card is a 32GB
SDHC card with FAT32 file system,
Class 10 and over.
Insert an SD card into the card reader
in the trunk. Disable the system from
the playback screen before removing
the SD card from the reader. Do not
remove the card while recording is
enabled. This could corrupt the video
file and/or the SD card.
Other files should not be stored on
the same SD card as the surround
vision recorder files. Storing other files
on the same card may increase
recording start up and playback time
or result in a loss of data.

1. Locate the capless funnel adapter.
2. Insert and latch the funnel into thecapless fuel system.
{Warning
Attempting to refuel from a
portable fuel container without
using the funnel adapter may cause
fuel spillage and damage the
capless fuel system. This could
cause a fire. You or others could be
badly burned and the vehicle could
be damaged.
3. Remove and clean the funnel adapter and return it to the storage
location.
Filling a Portable Fuel
Container
{Warning
Never fill a portable fuel container
while it is in the vehicle. Static
electricity discharge from the
container can ignite the fuel vapor.
You or others could be badly
burned and the vehicle could be
damaged. To help avoid injury to
you and others:
.Dispense fuel only into approved
containers.
.Do not fill a container while it is
inside a vehicle, in a vehicle's
trunk, in a pickup bed, or on any
surface other than the ground.
.Bring the fill nozzle in contact
with the inside of the fill opening
before operating the nozzle.
Maintain contact until filling is
complete.
.Keep sparks, flames, and
smoking materials away
from fuel.
(Continued)
Warning (Continued)
.Avoid using electronic devices
while pumping fuel.
Trailer Towing
General Towing
Information
Only use towing equipment that has
been designed for the vehicle. Contact
your dealer or trailering dealer for
assistance with preparing the vehicle
to tow a trailer. Read the entire
section before towing a trailer. To tow
a disabled vehicle, see Towing the
Vehicle 0371. To tow the vehicle
behind another vehicle such as a
motor home, see Recreational Vehicle
Towing 0372.
When towing with the 2.0L L4 engine,
only use unleaded gasoline with an
octane rating of 89 or higher. Using
gasoline with a lower octane rating
while towing may damage the engine
and may not be covered by the vehicle

.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian Braking (FPB)
If equipped with Lane Change Alert
(LCA), the LCA detection zones that
extend back from the side of the
vehicle do not move further back
when a trailer is towed. Use caution
while changing lanes when towing a
trailer.
If equipped with Rear Cross Traffic
Alert (RCTA), use caution while
backing up when towing a trailer, as
the RCTA detection zones that extend
out from the back of the vehicle do
not move further back when a trailer
is towed.
{Warning
To prevent serious injury or death
from carbon monoxide (CO), when
towing a trailer:
.Do not drive with the liftgate,
trunk/hatch, or rear-most
window open. (Continued)
Warning (Continued)
.Fully open the air outlets on or
under the instrument panel.
.Adjust the climate control
system to a setting that brings in
only outside air. See“Climate
Control Systems” in the Index.
For more information about carbon
monoxide, see Engine Exhaust
0 231.
Towing a trailer requires experience.
The combination of the vehicle and
trailer is longer and not as responsive
as the vehicle itself. Get used to the
handling and braking of the
combination by driving on a level road
surface before driving on public roads.
The trailer structure, the tires, and the
brakes must be all be rated to carry
the intended cargo. Inadequate trailer
equipment can cause the combination
to operate in an unexpected or unsafe
manner. Before driving, inspect all
trailer hitch parts and attachments,
safety chains, electrical connectors,
lamps, tires, and mirrors. See Towing
Equipment 0306. If the trailer has electric brakes, start the combination
moving and then manually apply the
trailer brake controller to check the
trailer brakes work. During the trip,
occasionally check that the cargo and
trailer are secure and that the lamps
and any trailer brakes are working.
Towing with a Stability Control
System
When towing, the stability control
system might be heard. The system
reacts to vehicle movement caused by
the trailer, which mainly occurs
during cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving without a trailer. This can help
to avoid heavy braking and sudden
turns.
Passing
More passing distance is needed when
towing a trailer. The combination of
the vehicle and trailer will not
accelerate as quickly and is much
longer than the vehicle alone. It is

HUD System
The windshield is part of the HUD
system. If the windshield needs to be
replaced, a GM replacement
windshield is recommended. The
replacement windshield must be
installed according to GM
specifications for proper alignment.
If it is not, the HUD image may look
out of focus.
Driver Assistance Systems
If the windshield needs to be replaced
and the vehicle is equipped with a
front camera sensor for the Driver
Assistance Systems, a GM replacement windshield is
recommended. The replacement
windshield must be installed
according to GM specifications for
proper alignment. If it is not, these
systems may not work properly, they
may display messages, or they may
not work at all. See your dealer for
proper windshield replacement.
Acoustic Windshield
The vehicle is equipped with an
acoustic windshield. If the windshield
needs to be replaced be sure to get an
acoustic windshield so you will
continue to have the benefits an
acoustic windshield can provide.
Gas Strut(s)
This vehicle is equipped with gas
strut(s) to provide assistance in lifting
and holding open the hood/trunk/
liftgate system in full open position.
{Warning
If the gas struts that hold open the

with enough force. If struts are
failing to hold the hood/trunk/
liftgate, do not operate. Have the
vehicle serviced.
Caution
Do not apply tape or hang any
objects from gas struts. Also do not
