uuAcuraWatchTMuCollision Mitigation Braking SystemTM (CMBSTM)
Driving
The CMBSTM may activate even when you are aw are of a vehicle ahead of you, or
when there is no vehicle ahead . Some examples of this are:
■When Passing
Your vehicle approaches another vehicle ah ead of you and you change lanes to pass.
■At an intersection
Your vehicle approaches or passes another vehicle that is making a left or right turn.
■With Little Chance of a Collision

Driving
■On a curve
When driving through curves, your vehicle comes to a point where an oncoming
vehicle is right in front of you.
■Through a low bridge at high speed
You drive under a low or na rrow bridge at high speed.
■Speed bumps, road work sites, tra in tracks, roadside objects, etc.
You drive over speed bumps, st eel road plates, etc., or your vehicle approaches train
tracks or roadside objects [such as a traffi c sign and guard rail] on a curve or, when
parking, stationary vehicles and walls.

uuAcuraWatchTMuLow Speed Braking Control*
Driving
Low Speed Braking Control*
Using sonar sensors located on the front an d rear bumpers, this system detects if
there is danger of a potential collision with a wall or other obstacle during normal
driving or when the accelerator pedal is de pressed with too much force. The system
then assists in avoiding collisions and reducing damage from impact through
assistive braking and/or assistive driving power suppression.1 Low Speed Braking Control*
If trapped in a railway crossing, the system may
detect the crossing gate as an obstacle and activate.
If this happens, assistive braking will automatically
cancel after a certain amount of time after stopping,
so continue to move forw ard. If assistive driving
power suppression is activate d, continue to calmly
depress the accelerator or depress the accelerator
once again, then push aside the crossing gate.
3WARNING
It is not possible for the Low Speed Braking
Control system to avoid collisions or reduce
damage from collision s in all situations
where the accelerator has been depressed
accidentally or with too much force.
Over reliance on this system may result in a
collision and serious injury or death.
It is your responsibility to always check your
shift position, pedal location and
surroundings, and safely operate the
vehicle.

■Assistive braking
Assistive braking provides a visual and audible alert when the vehicle is moving
between approximately 1 and 6 mph (2 and 10 km/h) and there is the possibility of
a collision with a detected wall or other ob stacles, as well as providing assistance
with braking.
If the only rear sensors are turned off usi ng the parking sensor system, the assistive
braking is not working when reversing.

For directions on the prop er handling of the sonar
sensors, please refer to the following page.

The vehicle will release the brake and start moving a
few seconds after the system is activated. To keep the
vehicle stopped, keep the brake pedal depressed or
put the transmission into

In order to prevent the sy stem from activating when
not needed, always turn it off during vehicle
maintenance, when loading on ships, trucks, and so
on, or when using a chassis dynamometer, free
rollers for inspection or when washing the car in

■Assistive driving power suppression
When the vehicle is stopped or moving at less than 6 mph (10 km/h) and there is an
obstacle such as a wall near the front of or back of the vehicle, if the accelerator pedal is
depressed more than necessary, the system will inform you with a visual and audible alert.
At the same time, the system will prevent sudden forward or backwards movement by
limiting the output of the engine, then assist ive braking will activate nearby the obstacle.
Assistive driving power suppression will no t activate in the following situations.
When moving forward:
When on a steep slope or the shift position is in
(P, (R, or (N.
When reversing:
When on a steep slope or the shift po sition is in a position other than
(R.
If the only rear sensors are turned off usin g the parking sensor system, the assistive
driving power suppression is not working when reversing.

Driving
When you turn the system on and off, do the
following.
1. Press the safety support switch.
2. Roll the right selector wheel to the
symbol and push it.
u The message appears on the driver
information interface when the system
becomes on or off.
u A check mark appears in the box and the
color of the symbol changes green
when the system is on. The check mark
disappear and the color of the symbol
changes gray when the system is off.
The system is turned on every time you start
the power system, even if you turned it off the
last time you drove the vehicle.

The Low Speed Braking Control system may
temporarily turn off after reconnecting the 12-volt
battery.
The system will automatically turn ON after the
vehicle has been moving at over 12 mph (20 km/h)
for some time.
If the system does not turn on, have your vehicle
checked by a dealer.

Driving
Conditions for assistive driving power suppression.
• When the accelerator is no longer depressed.
• When the accelerator is depresse d for approximately four seconds.
• When the brake pedal is depressed.
• When the steering wheel is tu rned and a collision avoided.
Conditions for assistive braking cancellation.
• A certain amount of time ha s passed since activation.
The system may not operate correct ly in the following conditions:
■Examples of obstacles the sonar sensor cannot detect
• Obstacles that do not refl ect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fences, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Moving objects or obstacles that suddenly enter the road.
• Obstacles that are not pe rpendicular to the ground.
■Conditions for Cancellation
■Low Speed Braking Control System Conditions and
Limitations
1 Conditions for Cancellation
After Low Speed Braking Control has activated once,
it will not activate again for the same obstacle.
They can be activated again after driving for a certain
distance after last activation.
Low Speed Braking Control ac tivates separately when
moving forward and reversing. (For example, if it
activates when moving forwar d, it can be activated
again immediately if reversing.)
However, if assistive braking has been activated, in
order to activate assistiv e driving power suppression
again, it is necessary to drive for a certain distance to
reset the system.

• The ambient temperature/humidity is too high or low.
• When going down a very steep slope.
• When close to other vehicles with sonar sensors or other objects that emit

• When passing through short or narrow gates.
• When driving on uneven surfaces, grassy areas, or places with steps.
• When a sloped pillar or wall is protruding from a high position.
• When there are obstacles next to the road.
