below bumper level. 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 Park Assist system does not
detect children, pedestrians,
cyclists, 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 Park Assist, always check
the area around the vehicle and
check all mirrors before moving
forward or reversing.
The instrument cluster may have a
park assist display with bars that
show distance to object and object
location information for the Park
Assist system. As the object gets
closer, more bars light up and the bars
change colour from yellow to amber
to red. An obstacle is also indicated by
audible beeps. The interval between
the beeps becomes shorter as the
vehicle gets closer to the obstacle.
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 FPA are higher pitched than
for RPA.
Reversing Warning and Reverse
Automatic Braking (RAB)
Vehicles with Adaptive Cruise Control
(ACC) have the Reversing Warning
System and Reverse Automatic
Braking (RAB) system. When in
R (Reverse), Reversing Warning alerts
of rear objects at vehicle speeds
greater than 8 km/h (5 mph), and RAB
may automatically brake hard at
speeds between 1 32 km/h (0.5
20 mph).
The Reversing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
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.
