.To increase vehicle speed in
larger increments, press +RES
up to the second detent. For
each press, the vehicle goes
5 km/h (5 mph) faster.
When it is determined that there is
no vehicle in front of your vehicle,
then the vehicle speed will increase
to the set speed.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster on
page 5‑9. The increment value used
depends on the units displayed.
Reducing Speed While ACC is at a
Set Speed
If ACC is already activated, do one
of the following:
.Use the brake to get to the
desired lower speed. Press
SET– down and release the
accelerator pedal. The vehicle
will now cruise at the lower
speed.
.Press and hold SET– down until
the desired lower speed is
reached, then release it.
.To decrease the vehicle speed in
smaller increments, press SET−
down to the first detent. For
each press, the vehicle goes
about 1 km/h (1 mph) slower.
.To decrease the vehicle speed in
larger increments, press SET−
down to the second detent. For
each press, the vehicle goes
about 5 km/h (5 mph) slower.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster on
page 5‑9. The increment value used
depends on the units displayed.
Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected. Press
3on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap
setting displays briefly on the
instrument cluster and HUD (if
equipped). The gap setting will be
maintained until it is changed.
Since each gap setting corresponds
to a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a
vehicle detected ahead. Consider
traffic and weather conditions when
selecting the following gap. The
range of selectable gaps may not be
appropriate for all drivers and
driving conditions.
Changing the gap setting
automatically changes the alert
timing sensitivity (Far, Medium,
or Near) for the Forward Collision
Alert (FCA) feature.

9-38 Driving and Operating
Alerting the Driver
If ACC is engaged, driver action
may be required when:
.ACC cannot apply sufficient
braking because of approaching
a vehicle too rapidly.
.A temporary condition prohibits
ACC from operating. See
Vehicle Messages on page 5‑34.
.A malfunction is detected in the
system. SeeVehicle Messages
on page 5‑34.
When any of these conditions occur,
the collision alert symbol on the
HUD (if equipped) will flash on the
windshield. Either eight beeps will
sound from the front, or both sides
of the Safety Alert Seat will pulse five times. See
“Collision/Detection
Systems” underVehicle
Personalization on page 5‑44.
See Defensive Driving on page 9‑3.
Approaching and Following a
Vehicle
The vehicle ahead symbol is located
in the HUD display.
The vehicle ahead symbol only
displays when a vehicle is detected
in your vehicle’s path.
If this symbol is not displaying, ACC
will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle
speed increases or decreases to follow the vehicle in front of you, but
will not exceed the set speed. It may
apply limited braking, if necessary.
When braking is active, the brake
lights will come on. The automatic
braking may feel or sound different
than if the brakes were applied
manually. This is normal.
Stationary or Very Slow-Moving
Objects
{WARNING
Adaptive Cruise Control (ACC)
may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system will not brake for a vehicle
that it has never detected moving.
This can occur when a detected
vehicle changes lanes at an
intersection or in stop-and-go
traffic and then a stopped or
slow-moving vehicle appears.
Your vehicle may not stop and
could cause a crash. Use caution

WARNING (CONTINUED)
when using ACC. Your complete
attention is always required while
driving and you should be ready
to take action and apply the
brakes.
ACC Automatically Disengages
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle when:
.The sensors are blocked.
.There is no traffic or other
objects to detect.
.There is a fault in the system.
The ACC active symbol will not be
displayed when ACC is no longer
active. Notification to Resume ACC
ACC will maintain a follow gap
behind a detected vehicle and slow
your vehicle to a stop behind that
vehicle.
If the vehicle ahead has driven
away and ACC has not resumed,
the vehicle ahead symbol will flash
as a reminder. In addition, the left
and right sides of the Safety Alert
Seat will pulse three times, or three
beeps will sound. See
”Alert Type”
and “Go Notifier” in“Collision/
Detection Systems” underVehicle
Personalization on page 5‑44.
When the vehicle ahead drives
away, press RES+ or the
accelerator pedal to resume cruise
control. If stopped for more than
two minutes or if the driver door is
opened and the driver safety belt is
unbuckled, the ACC automatically
applies the electric parking brake to
hold the vehicle. The electric
parking brake status light will turn
on. See Electric Parking Brake on
page 9‑26. To resume ACC and release the electric parking brake,
press the accelerator pedal and
then RES+.
{WARNING
If ACC has stopped the vehicle,
and if ACC is disengaged, turned
off, or canceled, the vehicle will
no longer be held at a stop. The
vehicle can move. When ACC is
holding the vehicle at a stop,
always be prepared to manually
apply the brakes.
{WARNING
Leaving the vehicle without
placing it in P (Park) can be
dangerous. Do not leave the
vehicle while it is being held at a
stop by ACC. Always place the
vehicle in P (Park) and turn off
the ignition before leaving the
vehicle.

9-40 Driving and Operating
ACC Override
If using the accelerator pedal while
ACC is active, a DIC warning
message will indicate that automatic
braking will not occur. SeeVehicle
Messages on page 5‑34. ACC will
resume operation when the
accelerator pedal is not being
pressed.
{WARNING
The ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
Curves in the Road
{WARNING
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle (Continued)
WARNING (CONTINUED)
accelerates up to the set speed,
especially when following a
vehicle exiting or entering exit
ramps. You could lose control of
the vehicle or crash. Do not use
ACC while driving on an entrance
or exit ramp. Always be ready to
use the brakes if necessary.
{WARNING
On curves, ACC may respond to
a vehicle in another lane, or may
not have time to react to a vehicle
in your lane. You could crash into
a vehicle ahead of you, or lose
control of your vehicle. Give extra
attention in curves and be ready
to use the brakes if necessary.
Select an appropriate speed while
driving in curves. ACC may operate differently in a
sharp curve. It may reduce the
vehicle speed if the curve is too
sharp.
When following a vehicle and
entering a curve, ACC may not
detect the vehicle ahead and
accelerate to the set speed. When
this happens, the vehicle ahead
symbol will not appear.

Driving and Operating 9-41
ACC may detect a vehicle that is
not in your lane and apply the
brakes.
ACC may occasionally provide an
alert and/or braking that is
considered unnecessary. It could
respond to vehicles in different
lanes, signs, guardrails, and other
stationary objects when entering or
exiting a curve. This is normal
operation. The vehicle does not
need service.Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Using ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on
steep hills or when towing a trailer.
The performance of ACC when
driving on hills and when towing a
trailer depends on the vehicle
speed, vehicle load, traffic
conditions, and steepness of the
hills. It may not detect a vehicle in
the lane while driving on hills. When
going up steep hills, the accelerator
pedal may need to be pressed to
maintain the vehicle speed. When
going downhill, especially when
towing a trailer, the brakes may
need to be applied by the driver to
slow the vehicle down. If the brakes
are applied, ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
.Step lightly on the brake pedal.
.Press*.

Audible or Safety Alert Seat
Some driver assistance features
alert the driver of obstacles by
beeping. To change the volume of
the warning chime, see“Comfort
and Convenience” underVehicle
Personalization on page 5‑44.
If equipped with the Safety Alert
Seat, the driver seat cushion may
provide a vibrating pulse alert
instead of beeping. To change this,
see “Collision/Detection Systems”
under Vehicle Personalization on
page 5‑44.
Assistance Systems for
Parking or Backing
When the vehicle is in R (Reverse),
the Rear Vision Camera (RVC) and
Rear Parking Assist may help the
driver to avoid a crash or to reduce
crash damage. Some models may
also have the Rear Automatic
Braking and Backing Warning
System, Rear Cross Traffic Alert
(RCTA), and/or Front Parking
Assist. When the vehicle is shifted into
R (Reverse), the RVC displays an
image of the area behind the vehicle
in the center stack display.
{WARNING
The RVC system does not display
children, pedestrians, bicyclists,
animals, or any other object
located outside the camera's field
of view, below the bumper,
or under the vehicle. Perceived
distances may be different from
actual distances. Do not back the
vehicle using only the RVC
screen, during longer, higher
speed backing maneuvers,
or where there could be cross
traffic. Failure to use proper care
before backing may result in
injury, death, or vehicle damage.
Always check behind and around
the vehicle before backing.

9-44 Driving and Operating
Displayed images may be farther or
closer than they appear. The area
displayed is limited and objects that
are close to either corner of the
bumper or under the bumper do not
display.
A warning triangle may display on
the RVC screen to show where the
Ultrasonic Rear Parking Assist
(URPA) has detected an object. This
triangle changes from amber to red
and increases in size the closer the
object.
On vehicles with the Rear Cross
Traffic Alert (RCTA), this triangle
with an arrow may also display on
the RVC screen to warn of traffic
coming from either direction. This
system detects objects coming from
up to 30 m (98 ft) from the left or
right side of the vehicle. When an
object is detected, either three
beeps sound or three Safety Alert
Seat pulses occur on the left or right
side, depending on the direction of
the detected vehicle.With URPA, as the vehicle backs up
at speeds of less than 8 km/h
(5 mph), the sensors on the rear
bumper detect objects up to 2.5 m
(8 ft) behind the vehicle that are
within a zone 25 cm (10 in) high off
the ground and below bumper level.
{WARNING
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at
speeds greater than 8 km/h
(5 mph). To prevent injury, death,
or vehicle damage, even with
parking assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.The instrument cluster parking
assist display has bars that show
“distance to object”
and object
location information for URPA, and
on some vehicles, the Front Parking
Assist system. As the object gets
closer, more bars light up. When an
object is first detected in the rear,
one beep will be heard from the
rear, or both sides of the Safety
Alert Seat will pulse two times.
When an object is very close
(<0.6 m (2 ft) in the vehicle rear,
or <0.3 m (1 ft) in the vehicle front),
five beeps will sound from the front
or rear, or both sides of the Safety
Alert Seat will pulse five times.
