218 DRIVING AND OPERATING
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. ACC will
not detect a vehicle in the lane while
driving on steep hills. The driver will
often need to take over acceleration
and braking on steep hills, especially
when towing a trailer. If the brakes are
applied, the ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
.Step lightly on the brake pedal.
. Press
*.
. Press
J.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off. Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror and the
radar sensors on the front of the
vehicle can become blocked by snow,
ice, dirt, or mud. These areas need to
be cleaned for ACC to operate
properly.
For cleaning instructions, see
“Washing the Vehicle
”under Exterior
Care 0324.
System operation may also be limited
under snow, heavy rain, or road spray
conditions.

DRIVING AND OPERATING 223
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 color 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 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.
Backing Warning and Reverse
Automatic Braking (RAB)
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning
System and Reverse Automatic
Braking (RAB) system. When in
R (Reverse), Backing 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 Backing 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.
{Warning
The Backing 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
backing 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 Backing Warning System,
always check the area around the
vehicle and check all mirrors before
backing.
When the vehicle is in R (Reverse),
if the system detects the vehicle is
backing too fast to avoid a crash with
a detected object behind your vehicle
in your path, it may automatically
brake hard to a stop to help avoid or
reduce the harm caused by a backing
crash.
