processing or similar purposes.
The Reverse Automatic Braking
(RAB) system will operate the
following 2 functions using 4
sonar sensors.
Sonar Audible Alarm
The Reverse Automatic Braking
(RAB) system detects objects rear-
ward and warns the driver by warn-
ing message on the multimedia
system screen an d warning beeps.
Automatic Braking
The automatic braking detects
objects rearward and if there is a
high risk of a co llision, the system
decelerates the vehicle and con-
trols the braking to reduce damage.
When reversing
When either strong automatic
braking or torque control is
applied to prevent collision (in
WARNING
●Reverse Automatic Braking
(RAB) is not a system intended
to replace the driver’s responsi-
bility to check their surroundings
for vehicles or obstacles to
avoid a collision.
●The driver is responsible for
driving safely. Before reversing,
be sure to first depress the
brake pedal and visually check
the surroundings.
●There are some cases in which
the vehicle cannot avoid colli-
sion, because the system oper-
ation has limitations. The
warning sound or automatic
braking may be delayed or may
not operate at all even when an
obstacle is present.
●Make sure to set the Automatic
Braking to OFF when the vehi-
cle is on the free roller or on the
chassis dynamometer. Other-
wise, the vehicle may move and
it may cause an accident.
●Make sure to set the Automatic
Braking to OFF when towing the
vehicle. Otherwise, the vehicle
may move and it may cause an
accident.
●The system is not designed to
detect people (including chil-
dren), animals or other moving
objects.
●Depending on the vehicle condi-
tion or the surrounding environ-
ment, the sonar sensor’s ability
to detect objects may become
unstable.

collisions by automatic hard brak-
ing when the vehicle’s reversing
speed is less than approximately
3 mph (5 km/h). However, the sys-
tem does not guarantee that the
vehicle will be able to avoid colli-
sions in any situation.
