9-48 Driving and Operating
On vehicles with the Rear Cross
Traffic Alert (RCTA), a 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 30 m (98 ft) from the left or
right side behind the vehicle. When
an object is detected, either three
beeps sound from the left or right
side 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.
With URPA, as the vehicle reverses
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.
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 reversing.
The instrument cluster parking
assist display has bars that show
distance to object and object
location information for URPA, and
on some vehicles, for the Front
Parking Assist system. As the object
gets closer, more bars light up and
the bars change colour from yellow
to amber to red. When an object is
first detected in the rear, one beep
will be heard from the rear, or both
sides of the Safety Alert Seat will
pulse two times. When an 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 Front
Parking Assist are higher pitched
than for Rear Parking Assist.
Vehicles with Adaptive Cruise
Control (ACC) have the Reversing
Warning System, which is designed
to help avoid reversing crashes. The
