applied. Once the power assist is used up, it
can take longer to stop and the brake pedal
will be harder to push.
Steering
Caution
To avoid damage to the steering system,
do not drive over curbs, parking barriers,
or similar objects at speeds greater than
3 km/h (1 mph). Use care when driving
over other objects such as lane dividers
and speed bumps. Damage caused by
misuse of the vehicle is not covered by
the vehicle warranty.
Electric Power Steering
The vehicle is equipped with an electric
power steering system, which reduces the
amount of effort needed to steer the
vehicle. It does not have power steering
fluid. Regular maintenance is not required.
If the vehicle experiences a system
malfunction and loses power steering,
greater steering effort may be required.
Power steering assist also may be reduced if
you turn the steering wheel as far as it can
turn and hold it there with force for an
extended period of time.
See your dealer if there is a problem.
Curve Tips
.Take curves at a reasonable speed.
.Reduce speed before entering a curve.
.Maintain a reasonable steady speed
through the curve.
.Wait until the vehicle is out of the curve
before accelerating gently into the
straightaway.
Steering in Emergencies
.There are some situations when steering
around a problem may be more effective
than braking.
.Holding both sides of the steering wheel
allows you to turn 180 degrees without
removing a hand.
.Antilock Brake System (ABS) allows
steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off the
edge of a road onto the shoulder while
driving. Follow these tips:1. Ease off the accelerator and then, if there is nothing in the way, steer the
vehicle so that it straddles the edge of
the pavement.

202 Driving and Operating
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick stop
and could cause pulling to one side. You
could lose control of the vehicle.
After driving through a large puddle of
water or a car/vehicle wash, lightly apply
the brake pedal until the brakes work
normally.
Flowing or rushing water creates strong
forces. Driving through flowing water
could cause the vehicle to be carried
away. If this happens, you and other
vehicle occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive through
flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build
up under the vehicle's tires so they actually
ride on the water. This can happen if the
road is wet enough and you are going fast
enough. When the vehicle is hydroplaning, it
has little or no contact with the road.There is no hard and fast rule about
hydroplaning. The best advice is to slow
down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather
driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in
good shape.
.Keep the windshield washer fluid reservoir
filled.
.Have good tires with proper tread depth.
See
Tires 0353.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain. Tips include:
.Keep the vehicle serviced and in good
shape.
.Check all fluid levels and brakes, tires, and
cooling system.
.Shift to a lower gear when going down
steep or long hills.
{Warning
Using the brakes to slow the vehicle on a
long downhill slope can cause brake
overheating, can reduce brake
performance, and could result in a loss of
braking. Shift the transmission to a lower
gear to let the engine assist the brakes
on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral) or with
the ignition off is dangerous. This can
cause overheating of the brakes and loss
of steering assist. Always have the engine
running and the vehicle in gear.
.Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
.Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
.Pay attention to special road signs (e.g.,
falling rocks area, winding roads, long
grades, passing or no-passing zones) and
take appropriate action.

available options and select “Collision/
Detection Systems”.
See Defensive Driving 0196.
Approaching and Following a Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD, if equipped.
It only displays when a vehicle is detected
in your vehicle’s path moving in the same
direction. If this symbol is not displaying,
ACC will not respond to or brake for vehicles
ahead.
ACC automatically slows the vehicle down
and adjusts vehicle speed to follow a
detected vehicle ahead at the selected
following gap. The vehicle speed increases or
decreases to follow a detected vehicle in
front of your vehicle when that vehicle is
traveling slower than your vehicle set speed.
It may apply limited braking, if necessary.
When braking is active, the brake lamps will come on. The automatic braking may feel or
sound different than if the brakes were
applied manually. This is normal.
Passing a Vehicle While Using ACC
If the set speed is high enough, and the left
turn signal is used to pass a vehicle ahead
in the selected following gap, ACC may
assist by gradually accelerating the vehicle
prior to the lane change.
{Warning
When using ACC to pass a vehicle or
perform a lane change, the following
distance to the vehicle being passed may
be reduced. ACC may not apply sufficient
acceleration or braking when passing a
vehicle or performing a lane change.
Always be ready to manually accelerate
or brake to complete the pass or lane
change.
Stationary or Very Slow-Moving Objects
{Warning
ACC may not detect and react to stopped
or slow-moving vehicles ahead of you. For
example, the system may not brake for a (Continued)
Warning (Continued)
vehicle it has never detected moving. This
can occur in stop-and-go traffic or when a
vehicle suddenly appears due to a vehicle
ahead changing lanes. Your vehicle may
not stop and could cause a crash. Use
caution when using ACC. Your complete
attention is always required while driving
and you should be ready to take action
and apply the brakes.
Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.Vehicles with cargo extending from the
back end.
.Non-standard shaped vehicles, such as
vehicle transport, vehicles with a side car
fitted, or horse carriages.
.Objects that are close to the front of your
vehicle.
ACC Automatically Disengages
ACC may automatically disengage and the
driver will need to manually apply the
brakes to slow the vehicle if:
.The sensors are blocked.

246 Driving and Operating
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. SeeRoof Rack System 092.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.
Cleaning the Sensing System
The camera sensor on the windshield behind
the rearview mirror, and the sensors on the
front of the vehicle can become blocked by
snow, ice, dirt, mud, or debris. This area
needs to be cleaned for ACC to operate
properly.
If ACC will not operate, regular cruise control
may be available. See “Switching Between
ACC and Regular Cruise Control” previously
in this section. Always consider driving
conditions before using either cruise control
system.
For cleaning instructions, see “Washing the
Vehicle” underExterior Care 0390.Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on Super Cruise-enabled roads
that are separated from opposing traffic.
Super Cruise can also steer to perform a
lane change under certain conditions on
Super Cruise-enabled roads.
A lane change can be initiated by the driver
using the turn signal lever.
The Super Cruise System may initiate a lane
change maneuver in following scenarios:
.to pass slower traffic
.when the current lane is ending ahead
.to return to the initial lane
See “Super Cruise Lane Change” later in this
section and Turn and Lane-Change Signals
0 139.
{Warning
Super Cruise can only assist to maintain
lane position, or steer to change lanes,
when driving on compatible roads. You
must supervise the driving task and
monitor the road conditions. You may
(Continued)
Warning (Continued)
need to respond to traffic events by
steering, braking, or accelerating. See
Defensive Driving.
Super Cruise is:
.Not a self-driving system
.Not a crash avoidance or warning
system
.Not a substitute for proper supervision
of the driving task.
Super Cruise uses the following to detect
the current lane position and lane markings
ahead on compatible roads under certain
conditions:
.Cameras
.Global Positioning System (GPS) sensing
.A high-precision map
.GPS-enhancement data downloaded
through OnStar
Super Cruise works with Adaptive Cruise
Control (ACC), which controls acceleration
and braking while Super Cruise is enabled
and operating. Review and understand both

252 Driving and Operating
Attention to the Road
{Warning
Super Cruise is a driver assistance system
and cannot accurately detect or predict
all situations. Super Cruise is not a crash
avoidance system. To prevent serious
injury or death, you must supervise the
driving task and monitor the road
conditions. You may need to respond to
traffic events by steering, braking,
or accelerating. SeeDefensive Driving
0 196. Super Cruise also cannot
determine whether you are awake,
asleep, impaired, or properly focused on
safe driving. The vehicle could crash into
other vehicles, drive out of the lane,
or drive off the road. Complete attention
is always required while driving, even
while using Super Cruise. Be prepared to
take over steering or apply the brakes at
any time.
{Warning
To prevent serious injury or death, be
alert and pay special attention when
passing highway exits, entrances, and
crossings with Super Cruise, and be ready
to take control of the vehicle when
necessary. Changes in lane markings
around exits and entrances can
momentarily cause Super Cruise to not
detect the correct lane. If this occurs,
Super Cruise may attempt steering inputs
to bring the vehicle back into the correct
lane and, in rare circumstances, could
over-correct and cause the vehicle to
momentarily cross into a lane next to
your vehicle unless you manually steer to
maintain your lane position. The Driver Attention System (DAS) on the
steering column continually monitors driver
head and eye position to estimate driver
attention to the road. The camera does not
record or share pictures, audio, or video.
Sunglasses, hats, or other types of clothing
that change the shape of the head may
interfere with camera performance. To
improve camera performance, raise or lower
the steering wheel, or change the seat
position.

If the vehicle is equipped with OnStar and
has an active service plan, additional data
may be collected through the OnStar
system. This includes information about: the
vehicle’s operation; a crash involving the
vehicle; the use of the vehicle and its
features; and, in certain situations, the
location and approximate GPS speed of the
vehicle. Refer to the OnStar Terms and
Conditions and Privacy Statement on the
OnStar website.
Location Services
This setting enables or disables sharing of
vehicle location outside the vehicle for
certain purposes. Even if the Location
Services setting is disabled, vehicle locationinformation will continue to be shared for
emergency services and Super Cruise,
if equipped.
System Care
The camera on the steering column has a
lens cover that may become dirty over time
and affect camera performance. Clean the
lens cover with a soft cloth sprayed with
glass cleaner. Wipe the lens gently, then dry
it. Never use abrasive cloths/cleaners or
corrosive chemicals of any kind on the lens
cover.
Super Cruise uses the front radar, front
camera, and 360 degree cameras for its
operation. Clean surfaces are required for
Super Cruise operation. See
Adaptive Cruise
Control (Advanced) 0236, “Surround Vision
Camera” underAssistance Systems for
Parking or Backing 0262, and Lane Keep
Assist (LKA) 0283 for care information.
Caution
The Super Cruise system is a highly
sophisticated system and should only be
serviced by technicians with the proper
training, tools, and safety instructions,
(Continued)
Caution (Continued)
which your dealer has. Without proper
training and tools the vehicle may
become damaged.
Driver Assistance Systems
This vehicle may have features that work
together to help avoid crashes or reduce
crash damage while driving, backing, and
parking. Read this entire section before
using these systems.
{Warning
Do not rely on the Driver Assistance
Systems. These systems do not replace
the need for paying attention and driving
safely. You may not hear or feel alerts or
warnings provided by these systems.
Failure to use proper care when driving
may result in injury, death, or vehicle
damage. See Defensive Driving 0196.
Under many conditions, these systems

Driving With a Trailer
Use caution while backing up when towing
a trailer. The RCTA feature is automatically
disabled when a trailer is attached to the
vehicle.
Turning the Features On or Off
To view available settings for this feature,
touch the Settings icon on the infotainment
home page. Select“Vehicle”to display the
list of available options and select “Collision/
Detection Systems”.
Assistance Systems for Driving
If equipped, when driving the vehicle in a
forward gear, Forward Collision Alert (FCA),
Front Pedestrian Braking (FPB), Lane Keep
Assist (LKA), Side Blind Zone Alert (SBZA),
Lane Change Alert (LCA), and/or Automatic
Emergency Braking (AEB) can help to avoid a
crash or reduce crash damage.
Forward Collision Alert (FCA)
System
If equipped, the FCA system may help to
avoid or reduce the harm caused by
front-end crashes. When approaching a
vehicle ahead too quickly, FCA provides a
red flashing alert on the windshield and rapidly beeps or pulses the driver seat. FCA
also lights an amber visual alert if following
another vehicle much too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 8 km/h (5 mph). If the vehicle
has Adaptive Cruise Control (ACC), it can
detect vehicles to distances of approximately
110 m (360 ft) and operates at all speeds.
See
Adaptive Cruise Control (Advanced)
0 236.
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of
pedestrians, animals, signs, guardrails,
bridges, construction barrels, or other
objects. Be ready to take action and
apply the brakes. See Defensive Driving
0 196. FCA can be disabled through vehicle settings.
To view available settings for this feature,
touch the Settings icon on the infotainment
home page. Select
“Vehicle”to display the
list of available options and select “Collision/
Detection Systems”.
Detecting the Vehicle Ahead
FCA warnings will not occur unless the FCA
system detects a vehicle ahead. When a
vehicle is detected, the vehicle ahead
indicator will display green. Vehicles may
not be detected on curves, highway exit
ramps, or hills, due to poor visibility; or if a
vehicle ahead is partially blocked by
pedestrians or other objects. FCA will not
detect another vehicle ahead until it is
completely in the driving lane.
