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
0400.
.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
(Continued)
Warning (Continued)
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).

The vehicle ahead indicator is
in the instrument cluster and
HUD display (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 follow 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
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.

Accessory Installations and
Vehicle Modifications
Do not install or place any
object around the front
camera windshield area that
would obstruct the front
camera view.
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. See Roof Rack
System0114.
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 can become
blocked by snow, ice, dirt, mud,
or debris. This area needs to
be cleaned for ACC to operate
properly. The vehicle headlamps may
need to be cleaned due to dirt,
snow, or ice. Objects that are
not illuminated correctly may
be difficult to detect.
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” under
Exterior Care 0440.
Super Cruise
If equipped, Super Cruise can
steer to maintain lane position
under certain conditions on
compatible highways that are
separated from opposing
traffic.
{Warning
Super Cruise can only assist
to maintain lane position
when driving on compatible
highways. You must
supervise the driving task
and monitor the freeway
conditions. You may need to
respond to traffic events by
steering, braking,
or accelerating. See
Defensive Driving 0240.
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

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. See
Defensive Driving0240.
Super Cruise also cannot
determine whether you are

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(Continued)

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.

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

features. The timing of both
alerts will vary based on
vehicle speed. The faster the
vehicle speed, the farther
away the alert will occur.
Consider traffic and weather
conditions when selecting the
alert timing. The range of selectable alert timings may
not be appropriate for all
drivers and driving conditions.
If your vehicle is equipped with
Adaptive Cruise Control (ACC),
changing the FCA timing
setting automatically changes

(DIC)
0144. The minimum
following time is 0.5 seconds
away. If there is no vehicle
detected ahead, or the vehicle
ahead is out of sensor range,
dashes will be displayed.
Unnecessary Alerts
FCA may provide unnecessary
alerts for turning vehicles,
vehicles in other lanes, objects
that are not vehicles, or shadows. These alerts are
normal operation and the
vehicle does not need service.
Cleaning the System
If the FCA system does not
seem to operate properly, this
may correct the issue:
.Clean the outside of the
windshield in front of the
rearview mirror.
.Clean the entire front of the
vehicle.
.Clean the headlamps.
Automatic Emergency
Braking (AEB)
The AEB system may help
avoid or reduce the harm
caused by front-end crashes.
AEB also includes Intelligent
Brake Assist (IBA). When the
system detects a vehicle
ahead in your path that is
traveling in the same direction
that you may be about to
crash into, it can provide a
boost to braking or
automatically brake the
