or the apply the accelerator pedal. Alerting the Driver
If ACC is engaged, driver action may be
required when ACC cannot apply sufficient
braking because your vehicle is approaching
a vehicle ahead too quickly.
When this condition occurs, the red collision
alert symbol 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. To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
See
Defensive Driving 0183.
Approaching and Following a Vehicle
The vehicle ahead indicator light is displayed
in the instrument cluster and the HUD,
if equipped. It only displays when a vehicle
is detected in your vehicle’s path and is
moving in the same direction. If the vehicle
ahead indicator light does not appear in the
instrument cluster, then ACC will not
respond to, or brake for, vehicles ahead.
While ACC is active, ACC will automatically
adjust your vehicle’s speed to follow a
detected vehicle ahead according to the
selected following gap setting. ACC may
decrease your vehicle’s cruise speed when
following a detected vehicle ahead that is
traveling slower than your ACC set speed.
ACC may apply limited braking, if necessary.
When ACC automatic braking is active, the
brake lamps will turn 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.

224 Driving and Operating
{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. 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.
.The Traction Control System (TCS) or
StabiliTrak/ESC system has activated or
has been disabled.
.If equipped with Air Suspension, the
vehicle ride height is outside normal
operating range. See Air Suspension0211.
.There is a fault in the system.
.The radar falsely reports a blockage when
driving in a remote area with no other
vehicles or roadside objects.
A DIC message may display to indicate that
ACC is temporarily unavailable. The ACC indicator light will turn white when
ACC is disengaged.
In some cases, when ACC is temporarily
unavailable, regular cruise control may be
used. See
“Switching Between ACC and
Regular Cruise Control” previously in this
section. Always consider driving conditions
before using either cruise control mode.
Notification to Resume ACC
ACC will maintain a follow distance gap
behind a detected vehicle, and will slow
down your vehicle to a stop behind that
vehicle.
If the stopped vehicle ahead has driven
away and ACC has not resumed, the vehicle
ahead indicator will flash as a reminder to
check traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three times,
or three beeps will sound. To view available
settings from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems > Alert Type > Adaptive Cruise Go

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 it off before leaving the
vehicle.
ACC Override
If you apply the accelerator pedal while ACC
is engaged, the ACC indicator light turns
blue in the instrument cluster and the HUD,
if equipped, indicating that ACC braking will
not occur. ACC will resume operation when
the accelerator pedal is released.
{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 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 when the
vehicle approaches a sharp curve in the road
ahead. If the ACC system detects that a

226 Driving and Operating
curve is too sharp, ACC may temporarily
reduce the vehicle speed while navigating
the curve.
The curve speed control indicator light
b
may illuminate green when ACC is actively
controlling the vehicle speed and detects a
sharp curve in the road ahead.
ACC may automatically increase the vehicle
speed when exiting out of the curve,
however ACC will not exceed the set speed.
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 indicator will not
appear.
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 or 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. You may need to
manually apply the brakes.
Objects Not Directly in Front of Your Vehicle
The ACC system may not be able to detect
all objects in front of the vehicle if:
.The vehicle or object ahead is not within
your lane.
.The vehicle ahead is shifted, not centered,
or is shifted to one side of the lane.
Driving in Narrow Lanes
Vehicles in adjacent traffic lanes or roadside
objects may be incorrectly detected when
located along the roadway.
Do Not Use ACC on Hills
Do not use ACC when driving on steep hills.
ACC will not detect a vehicle ahead.
