of the vehicle appears on the
infotainment display to aid with
parking and low-speed maneuvers.
See“Front Vision Camera ”under
Assistance Systems for Parking or
Backing 0253.
Rear Vision Camera (RVC)
If equipped, RVC shows a view of the
area behind the vehicle on the
infotainment display when the vehicle
is shifted into R (Reverse) to aid with
parking and low-speed backing
maneuvers.
See Assistance Systems for Parking or
Backing 0253.
Rear Cross Traffic Alert
(RCTA) System
If equipped, the RCTA system shows a
triangle with an arrow on the
infotainment display to warn of traffic
behind your vehicle that may cross your vehicle's path while in
R (Reverse). In addition, beeps will
sound, or the driver seat will pulse.
See
Assistance Systems for Parking or
Backing 0253.
Park Assist
If equipped, Rear Park Assist (RPA)
uses sensors on the rear bumper to
assist with parking and avoiding
objects while in R (Reverse).
It operates at speeds less than 8 km/h
(5 mph). RPA may show a warning
triangle on the infotainment display
and a graphic on the instrument
cluster to provide the object distance.
In addition, multiple beeps or seat
pulses may occur if very close to an
object.
The vehicle may also have the Front
Park Assist system.
See Assistance Systems for Parking or
Backing 0253.
Automatic Parking
Assist (APA)
If equipped, the APA system helps to
search for and maneuver the vehicle
into parallel or perpendicular parking
spots using automatic steering,
displays, and beeps. When the vehicle
speed is below 30 km/h (18 mph),
touch
Oto enable the system.
See “Automatic Parking Assist (APA)”
under Assistance Systems for Parking
or Backing 0253.
Reverse Automatic
Braking (RAB)
If the vehicle has Adaptive Cruise
Control (ACC) it also has the RAB
system, which is designed to help
avoid or reduce the harm caused by
backing crashes when the vehicle is
shifted into R (Reverse). If the system
detects the vehicle is backing too fast
to avoid a crash with a detected object
behind your vehicle in your path, it
may automatically brake hard to
a stop.

The high beams may not turn off
automatically if the system cannot
detect another vehicle's lamps because
of any of the following:
.The other vehicle's lamps are
missing, damaged, obstructed from
view, or otherwise undetected.
. The other vehicle's lamps are
covered with dirt, snow, and/or
road spray.
. The other vehicle's lamps cannot

The increment value used depends on
the units displayed.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to increase
the vehicle speed. When you take your
foot off the pedal, the vehicle will slow
down to the previous set cruise speed.
While pressing the accelerator pedal
or shortly following the release to
override cruise, briefly applying SET−
will result in cruise set to the current
vehicle speed.
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of the
hills. When going up steep hills, you
might have to step on the accelerator
pedal to maintain your speed. When
going downhill, the cruise control
system may automatically brake to
slow the vehicle down. Also, you may
have to brake or shift to a lower gear
to keep your speed down. If the brake
pedal is applied, cruise control
disengages. Ending Cruise Control
There are four ways to end cruise
control:
.
Step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. Press
J.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows for selecting
the cruise control set speed and
following gap. Read this entire section
before using this system. ACC uses a
camera and radar sensors to detect
other vehicles. See Radio Frequency
Statement 0411. The following gap is
the following time (or distance)
between your vehicle and a vehicle
detected directly ahead in your path, moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates while ACC is
engaged, ACC may automatically
disengage. See
Traction Control/
Electronic Stability Control 0220. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak/ESC is disabled.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop

234 DRIVING AND OPERATING
Approaching and Following a
Vehicle
The vehicle ahead indicator is on the
instrument cluster and HUD display.
This indicator only displays when a
vehicle is detected in your vehicle’s
path moving in the same direction.
If this indicator 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 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 lamps will
come on. The automatic braking mayfeel or sound different than if the
brakes were applied manually. This is
normal.
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.
ACC Automatically Disengages
ACC may automatically disengage and
you 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 been disabled.
. There is a fault in the system.
. The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects. A DIC message
may display to indicate that ACC
is temporarily unavailable.
The ACC indicator will turn white
when ACC is no longer active.
In some cases, when ACC will not
activate, 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 system.

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.
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. For
towing capability, seeTrailer Towing
0 284. ACC will not detect a vehicle in
the lane while driving on steep hills.
The driver will often need to take over
acceleration and braking on steep
hills, especially when towing a trailer.
If the brakes are applied, the ACC
disengages.
Disengaging ACC
There are three ways to
disengage ACC:
. Step lightly on the brake pedal.
. Press
*.
. Press
J.
Erasing Speed Memory
The ACC set speed is erased from
memory if
Jis pressed or if the
ignition is turned off.
Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror and the
radar sensors on the front of the
vehicle can become blocked by snow, ice, dirt, or mud. These areas need 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 ”under Exterior
Care 0372.
System operation may also be limited
under snow, heavy rain, or road spray
conditions.
