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 5-43.
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 5-43.
Assistance Systems for
Parking or Backing
When the vehicle is in R (Reverse),
the Rear Vision Camera (RVC) and
Rear Parking Assist (RPA) may help
the driver to avoid a crash or to
reduce crash damage. Some
models may also have Front
Parking Assist (FPA) and Rear
Cross Traffic Alert (RCTA). When the vehicle is shifted into
R (Reverse), the RVC displays an
image of the area behind the vehicle
in the center stack display. The
previous screen displays when the
vehicle is shifted out of R (Reverse)
after a short delay. To return to the
previous screen sooner, press a
button on the infotainment system,
shift into P (Park), or reach a vehicle
speed of 8 km/h (5 mph).
{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

Warning (Continued)
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.

1. View Displayed by the Camera
2. Corners of the Rear Bumper
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
RPA has detected an object. This
triangle changes from amber to red
and increases in size the closer the
object.
On vehicles with the RCTA, a red
warning triangle with a left or right
pointing arrow may also display on
the RVC screen to warn of trafficcoming from the left or right. 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, either three
beeps sound from the left or right or
three Safety Alert Seat pulses occur
on the left or right side, depending
on the direction of the detected
vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out
from the back of the vehicle do not
move further back when a trailer is
towed.
With RPA, and if equipped with FPA,
as the vehicle moves at speeds of
less than 8 km/h (5 mph) the
sensors on the bumpers detect
objects up to 2.5 m (8 ft) behind and
1.2 m (4 ft) in front of the vehicle
within a zone 25 cm (10 in) high off
the ground and below bumper level.
These detection distances may be
less during warmer or humid
weather.
{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.
