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
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 an d reducing damage from impact through
assistive braking and/or assistive driving power suppression.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), simply 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.

■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.

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 detected 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 ti me, the system will prevent sudden forward
or backwards movement by limiting the outpu t of the engine, then assistive braking
will activate nearby the obstacle.
Assistive driving power suppr ession will not 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 position is in a position other than
(R.
If the only rear sensors are turned off using the parking sensor system, the assistive
driving power suppression is not working when reversing.

Conditions for assistive driving power suppression.
• When the accelerator is no longer depressed.
• When the accelerator is depressed 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
1Conditions 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.

■Examples of situations where the sonar sensor cannot detect obstacles
• The sonar sensor is dirty (cover ed by snow, water, mud, etc.).
• The vehicle is too hot or cold.
• The steering wheel is turned sharply when approaching the obstacle at an angle.
■Examples of other cases where the system may not work correctly
• The vehicle is tilted due to heavy load or su spension modifications.
• An abnormal tire or wheel condition (inco rrect sizes, varied sizes or construction,
improperly inflated, co mpact spare tire, etc.).
• Bad weather conditions such as heav y rain, fog, snow, sandstorms, etc.
• 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
ultrasonic waves.
■Situations where the system may acti vate even without risk of a collision
• 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.
• When driving toward flags, curtains, tre e branches, railroad crossing bars, etc.
• When driving on flooded roads.

■Location and range of sensors
The sonar sensors are situated in the front and rear bumpers.1Sonar Sensors*
For the sonar sensors to work properly, do not:•Place stickers or other objects on or around the
sensors.
•Hit the area around the sensors.•Attempt to take apart any sensor.
•Put any accessories on or around the sensors.
Consult with a dealer if:
•A sensor has been subjected to shock.
•Work needs to be done to the area around a
sensor.
In the following cases, the sonar sensors may not
work properly. Have your ve hicle checked by a dealer.
•The front or rear bumper has made contact with a
hill, parking block, curb, embankment, etc.
•The vehicle has been involv ed in frontal or rear
collision.
•The vehicle has been driven through a deep
puddle.
