Driving and Operating 9-41
conditions allow ACC to be safely
used, the ACC can be turned
back on.
ACC will not engage if the TCS or
electronic stability control system 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 ahead, or enter your lane.
Also see“Alerting the Driver” in
this section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving on page 9-3.
{Warning
Adaptive Cruise Control will not
detect or brake for children,
pedestrians, animals, or other
objects.
Do not use Adaptive Cruise
Control when:
.On winding and hilly roads or
when the sensors are
blocked by snow, ice, or dirt.
The system may not detect a
vehicle ahead. Keep the
entire front of the vehicle
clean.
.Visibility is low, such as in
fog, rain, or snow conditions.
Adaptive Cruise Control
performance is limited under
these conditions.
.On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
](On/Off): Press to turn the
system on or off. The indicator turns
white on the instrument cluster
when ACC is turned on.
RES+ (Resume/Accelerate):
Press the control up briefly to make
the vehicle resume to a previously
set speed, or hold upwards to
accelerate. If cruise control is
already active, use to increase
vehicle speed.

1. View Displayed by the Camera
1. View Displayed by the Camera
2. Corners of the Rear BumperDisplayed 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
Rear Parking Assist (RPA) 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), a red warning
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 20 m
(65 ft) from the left or right side of
the vehicle. When an object is
detected, three beeps sound from
the left or right side, depending on
the direction of the detected vehicle.With RPA, 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.
If the vehicle has the Front Parking
Assist (FPA), it also detects objects
1.2 m (4 ft) in front of the vehicle.
These detection distances may be
shorter during warmer or humid
weather. Blocked sensors will not
detect objects and can also cause
false detections. Keep the sensors
clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car
wash in freezing temperatures.
{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
