Warning (Continued)
If LKA only detects lane
markings on one side of the
road, it will only assist or
provide an LDW alert when
approaching the lane on the
side where it has detected a
lane marking. Even with LKA
and LDW, you must steer
the vehicle. Always keep
your attention on the road
and maintain proper vehicle
position within the lane,
or vehicle damage, injury,
or death could occur. Always
keep the windshield,
headlamps, and camera
sensors clean and in good
repair. Do not use LKA in
bad weather conditions or
on roads with unclear lane
markings, such as
construction zones.
{Warning
Using LKA on slippery roads
could cause loss of control
of the vehicle and a crash.
Turn the system off.
{Warning
LKA will not alert the driver
if a towed trailer crosses
into an adjacent lane of
travel. Serious injury or
property damage may occur
if the trailer moves into
another lane. Always
monitor the trailer position
while towing to make sure it
is within the same lane as
the tow vehicle.
How the System Works
LKA uses a camera sensor
installed on the windshield
ahead of the rearview mirror
to detect lane markings. It may
provide brief steering assist if
it detects an unintended lanedeparture. It may further
provide an audible alert or the
driver seat may pulse
indicating that a lane marking
has been crossed. The system
does not provide a Lane
Departure Warning (LDW)
when intentionally steering
across a lane marker.
To turn LKA on and off, press
non the center console.
If equipped, the indicator light
on the button comes on when
LKA is on and turns off when
LKA is disabled. On some
vehicles, a long press of over
three seconds is required to
turn LKA off.
When on,

(LDW) alert by flashingn
amber if the vehicle crosses a
detected lane marking.
Additionally, there may be
three beeps, or the driver seat
may pulse 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
minimum recommended SD
card specifications are at least
64GB with exFAT file system,
Class V30 or greater.

REDUCED ACCELERATION
DRIVE WITH CARE :The
accelerator pedal response is
reduced and the remaining
range value changes to LOW,
charge the vehicle
immediately. See Propulsion
Power Messages 0135.
OUT OF ENERGY, CHARGE
VEHICLE NOW : The battery
charge is fully depleted. The
vehicle will slow to a stop.
Brake and steering assist will
continue operating. Once
stopped, turn the vehicle off.
Plug-In Charging
Plug-in charge times vary
based on the battery
condition, charge level, and the
outside temperature. See
Charging 0123 for charge
mode selection.
Do not allow the vehicle to
remain in temperature
extremes for long periods
without being driven or
plugged in. When
temperatures are below 0 °C (32 °F) and above 32 °C (90 °F),
plug in the vehicle to maximize
high voltage battery life.
In extreme temperature
conditions, a full charge will
take additional time.
It is normal to hear fans,
pumps, and electrical devices
clicking while the vehicle is
turned off and charging.
The vehicle does not require
indoor charging area
ventilation before, during,
or after charging.
The vehicle cannot be driven
while the charge cord is
plugged into the vehicle.
Caution
To avoid damage to the
vehicle, make sure the
charging cord plug is in good
condition, is not worn or
damaged, and is connected
securely to the vehicle's
charging port. If vehicle
charging is intermittent,
(Continued)
Caution (Continued)
disconnect the cord and
inspect for damage. An
excessively worn or
damaged AC or DC charging
cord plug may result in an
intermittent connection and
potential damage to the
vehicle's charging port.
There are several infotainment
screens that will display
depending on the current
charging status. See Charging
0 123.
Charging Override
A CHARGING OVERRIDE/
INTERRUPTION OCCURRED
message may display to
indicate that a charging
override or interruption has
occurred due to one or more
of the following events:
.Override of the charge
settings by the owner.
.Unintended interruption of
AC power at the vehicle's
charge port.

.Automatic Emergency
Braking (AEB)
.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.
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive
as the vehicle itself. Become
familiar with 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
0303. 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 to 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
necessary to go much farther
beyond the passed vehicle
before returning to the lane.
Pass on level roadways. Avoid
passing on hills if possible.
Backing Up
Hold the bottom of the
steering wheel with one hand.
To move the trailer to the left,
move that hand to the left. To

Wheels and Tires
Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer.
See the warranty manual
for information regarding
the tire warranty and
where to get service. For
additional information refer
to the tire manufacturer.

Vehicle Care 355
Warning (Continued)
When replacing wheels, use
a new GM original
equipment wheel.
Caution
The wrong wheel can also
cause problems with bearing
life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle
ground clearance, and tire or
tire chain clearance to the
body and chassis.
Tire Chains
Caution
If the vehicle is equipped
with tire size 265/50R20,
use tire winter traction
devices only where legal and
only when necessary. Only
use textile traction devices,(Continued)
Caution (Continued)
such as tire snow socks,
that are the proper size for
the tires. Traction devices
must be installed only on the
tires of the drive axle. Drive
slowly and follow the
traction device
manufacturer’s instructions.
Driving too fast or spinning
the wheels can damage the
traction device.
If a Tire Goes Flat
It is unusual for a tire to blow
out while driving, especially if
the tires are maintained
properly. If air goes out of a
tire, it is much more likely to
leak out slowly. See Tires
0334 for additional
information. But if there ever
is a blowout, here are a few
tips about what to expect and
what to do:
If a front tire fails, the flat tire
creates a drag that pulls the
vehicle toward that side. Take your foot off the accelerator
pedal and grip the steering
wheel firmly. Steer to maintain
lane position, and then gently
brake to a stop, well off the
road, if possible.
A rear blowout, particularly on
a curve, acts much like a skid
and may require the same
correction as used in a skid.
Stop pressing the accelerator
pedal and steer to straighten
the vehicle. It may be very
bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
The vehicle has no spare tire,
no tire changing equipment,
and no place to store a tire.
If the vehicle has self-sealing
tires, see Self-Sealing Tires
0
336. Tread punctures
typically will not cause tires to
lose air. However, if the vehicle
does get a flat tire, there is no
spare tire, tire changing
equipment, or place to store a
tire. Contact Roadside Service
0 388 for help.

368 Vehicle Care
Caution (Continued)
used on roads for conditions
such as dust and ice. Always
wash the chrome with soap
and water after exposure.
Caution
To avoid surface damage on
wheels and wheel trim, do
not use strong soaps,
chemicals, abrasive polishes,
cleaners, or brushes. Use
only GM approved cleaners.
Do not drive the vehicle
through an automatic car
wash that uses silicon
carbide tire/wheel cleaning
brushes. Damage could
occur and the repairs would
not be covered by the
vehicle warranty.
Brake System
Visually inspect brake lines
and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Inspect disc brake padsfor wear and rotors for
surface condition. Inspect all
other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,
suspension, and chassis
components for damaged,
loose, or missing parts or signs
of wear at least once a year.
Inspect power steering for
proper electrical connections,
binding, cracks, chafing, etc.
Visually check constant
velocity joint boots and axle
seals for leaks.
Body Component
Lubrication
Lubricate all key lock cylinders,
hood hinges, and liftgate
hinges unless the components
are plastic. Applying silicone
grease on weatherstrips with
a clean cloth will make them
last longer, seal better, and
not stick or squeak.
Underbody Maintenance
At least twice a year, spring
and fall, use plain water to
flush any corrosive materials
from the underbody. Take care
to thoroughly clean any areas
where mud and other debris
can collect.
Do not directly power wash
the transfer case and/or
front/rear axle output seals.
High pressure water can
overcome the seals and
contaminate the fluid.
Contaminated fluid will
decrease the life of the
transfer case and/or axles and
should be replaced.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the
body repair shop applies
anti-corrosion material to
parts repaired or replaced to
restore corrosion protection.
