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 depending
where the object is detected, or both
sides of the Safety Alert Seat will
pulse five times. Beeps for FPA are
higher pitched than for RPA.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA shows a red
warning triangle with a left or right
pointing arrow on the infotainment
display to warn of traffic coming from
the left or right. This system detects
objects coming from up to 20 m
(65 ft) from the left or right-hand 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 reversing 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.
Turning the Features On or Off
Press on the center stack to turn
on or off the Front and Rear Parking
Assist and Rear Cross Traffic Alert
system at the same time. The
indicator light next to the button
comes on when the features are on
and turns off when the features have
been disabled.
Turn off parking assist when towing a
trailer.
To turn the rear parking assist
symbols on or off, see Rear Camera
under Vehicle Personalisation 0 143.
RCTA can also be turned on or off
through vehicle personalisation. See
Collision/Detection Systems under
Vehicle Personalisation 0 143.
Automatic Parking Assist (APA)
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still change
gears, and control the brakes and
accelerator. A display and audible
beeps help to guide parking
maneuvers.
Warning
APA does not apply the brakes. APA
may not detect objects in the
parking space, objects that are soft
or narrow, objects high off the
ground such as flat-bed trucks,
or objects below ground level such
as large potholes. Always verify that
the parking space is appropriate for
parking a vehicle. APA does not
respond to changes in the parking
space, such as movement of an
adjacent vehicle, or a person or
object entering the parking space.
APA does not detect or avoid traffic
that is behind or alongside of the
