The instrument cluster may have a
parking assist display with bars that
show distance to object and object
location information for the 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 on object
location, 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.
Reversing Warning and Rear
Automatic Braking
Vehicles with Adaptive Cruise
Control (ACC) have the (RAB)
system. The Reversing Warning part
of this system can warn of rear
objects when reversing up at
speeds greater than 8 km/h (5 mph).
The Reversing Warning System will
beep once from the rear when a
potential object threat is first
detected, or pulse twice on both
sides of the Safety Alert Seat. When
the system detects a potential
imminent crash, beeps will be heard
from the rear, or five pulses will be
felt on both sides of the Safety Alert
Seat. There may also be a brief,
sharp application of the brakes.
Driving and Operating
Warning
The Reversing Warning System
only operates at speeds greater
than 8 km/h (5 mph). It does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
In some situations, such as at
higher reversing speeds, there
may not be enough time for the
short, sharp application of the
vehicle brake system to occur. To
prevent injury, death, or vehicle
damage, even with the Reversing
Warning System, always check
the area around the vehicle and
check all mirrors before reversing.
When the vehicle is in R (Reverse)
and if it is reversing too fast to avoid
a crash with a detected object
directly behind the vehicle, the Rear
Automatic Braking (RAB) system
