Driving
The system has three alert stages for a possible collis ion. However, depending on circumstances, the CMBSTM may not go through all of
the stages before initiating the last stage.

Driving
When you turn the CMBSTM 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 multi-
information display when the system
turns 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
disappears and the color of the
symbol changes gray when the system is
off.
The CMBS
TM is turned on every time you start
the engine, even if you turned it off the last
time you drove the vehicle.
■CMBSTM On and Off1 Collision Mitigation Braking SystemTM (CMBSTM)
The CMBS
TM may automatically shut off, and the
safety support indicator (amb er) will come and stay
on under certain conditions:

When the CMBS
TM is activated, it will continue to
operate even if the accele rator pedal is partially
depressed. However, it w ill be canceled if the
accelerator pedal is fully depressed.

come on under certain conditions. Some examples of these conditions are listed
below. Other conditions may reduce some of the CMBS
TM functions.

■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between objects and the background.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Roadway objects or structures are misint erpreted as vehicles and pedestrians.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,

• The road is hilly or the vehicle is approaching the crest of a hill.
■CMBSTM Conditions and Limitations1Collision Mitigation Braking SystemTM (CMBSTM)
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).

• An abnormal tire or wheel condition (incor rect sizes, varied sizes or construction,
improperly inflated, compact spare tire
*, etc.).
• When tire chains are installed.
• The vehicle is tilted due to a heav y load or suspension modifications.

■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The distance between your vehicle and the vehicle or pedestrian ahead of you is
too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• When you accelerate rapidly and approach the vehicl e or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved, winding or undulating road that makes it difficult for
the sensor to properly detect a vehicle in front of you.
• The speed difference between your vehicle an d a vehicle or pedestrian in front of
you is significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Another vehicle suddenly comes in front of you at an intersection, etc.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.
• When driving through a narrow iron bridge.
• When the lead vehicl e suddenly slows down.

uuAcuraWatchTMuCollision Mitigation Braking SystemTM (CMBSTM)
Driving
• When there is a group of people in front of your vehicle walking together side by
side.
• Surrounding conditions or belongings of the pedestrian alter the pedestrian’s
shape, preventing the system from recogn izing that the person is a pedestrian.
• When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.
• When a pedestrian blends in with the background.
• When a pedestrian is bent over or squa tting, or when their hands are raised or
they are running.
• When several pedestrians are walking ahead in a group.
• When the camera cannot correctly identify that a pedestrian is present due to an
unusual shape (holding luggage, body position, size).
■Automatic shutoff
The CMBSTM may automatically shut itself o ff and the safety support indicator
(amber) comes and stays on when:
• The temperature inside the system is high.
• You drive off-road or on a mountain road, or curved and wi nding road for an
extended period.
• An abnormal tire condition is detected (wrong tire size, flat tire, etc.).
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
Once the conditions that caused the CMBS
TM to shut off improve or are addressed
(e.g., cleaning), the system comes back on.

The CMBSTM may activate even when you are aware 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 ve hicle that is making a left or right turn.

■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 narrow bridge at high speed.
■Speed bumps, road work sites, tr ain tracks, roadside objects, etc.
You drive over speed bumps, steel road plates, etc., or yo ur 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.

Continued
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. The system then assists in avoiding collisions and reducing damage from
impact through assistive braking.1 Low Speed Braking Control*
If the Low Speed Braking Control activates in a
situation where you do not want automatic brake
application (such as when the vehicle is between two
railroad crossing gates), si mply press the brake pedal
to deactivate the system and then continue to drive
as intended.
3WARNING
The Low Speed Braking Control System
cannot avoid all collisions and may not
reduce damage in each situation where the
accelerator is mistaken ly or aggressively
pressed.
Overreliance on the system may result in a
collision with serious injury or death.
Always check your surroundings, your shift
position, and your pedal use. Driver
remains responsible for safely operating
the vehicle.

Driving
The Low Speed Braking Control 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 obstacle, as well as providing
assistance with braking.
If the only rear sensors are turned off usin g the parking sensor system, the assistive
braking is not working when reversing.

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 chas sis dynamometer or free
rollers for inspection or when washing the car in
