Collision Mitigation Braking System (CMBS)

Driving

Collision Mitigation Braking System (CMBS)

Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBS is designed to alert you when a
potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.

Collision Mitigation Braking System (CMBS)

Important Safety Reminder

The CMBS is designed to reduce the severity of an
unavoidable collision. It does not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately according to the driving
conditions.

When the CMBS activates, the engine may stop
automatically.
Start the engine by normal operation if the engine
stops.

The CMBS may not activate or may not detect a
vehicle in front of your vehicle under certain

How the System Works

How the System Works

When the CMBS activates, it may automatically apply
the brake. It will be cancelled when your vehicle stops
or a potential collision is not determined.

The system starts monitoring the roadway ahead when your vehicle speed is about
5 km/h (3 mph) and there is a vehicle in front of you.

The radar sensor is
in the front grille.

The CMBS activates when:

●

The speed difference between your vehicle and a vehicle or pedestrian detected
in front of you becomes about 5 km/h (3 mph) and over with a chance of a
collision.

●

Your vehicle speed is about 100 km/h (62 mph) or less and the system determines
there is a chance of a collision with:

- Vehicles detected in front of you that are stationary, oncoming, or travelling in
your same direction.
- A pedestrian who is detected in front of you.

●

Your vehicle speed is above 100 km/h (62 mph), and the system determines there
is a chance of a collision with a vehicle detected in front of you travelling in your
same direction.

The camera is
located behind
the rearview
mirror.

How the System Works

The camera in the CMBS is also designed to detect
pedestrians.
However, this pedestrian detection feature may not
activate or may not detect a pedestrian in front of
your vehicle under certain conditions.
Refer to the ones indicating the pedestrian detection
limitations from the list.

Adaptive Cruise Control (ACC) with Low Speed
Follow (LSF)

Helps to maintain a constant vehicle speed and a set following-interval behind a
vehicle detected ahead of yours and, if the detected vehicle comes to a stop, can
decelerate and stop your vehicle, without you having to keep your foot on the brake
or the accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle’s brake
lights will illuminate.

Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)

Important Reminder

As with any system, there are limits to ACC with LSF. Use
the brake pedal whenever necessary, and always keep a
safe interval between your vehicle and other vehicles.

sensor, refer to the following page.

WARNING

Improper use of ACC with LSF can lead to a
crash.

Use ACC with LSF only when driving on
motorways and in good weather
conditions.

WARNING

ACC with LSF has limited braking capability
and may not stop your vehicle in time to
avoid a collision with a vehicle that quickly
stops in front of you.

Always be prepared to apply the brake
pedal if the conditions require.

■

Vehicle speed for ACC with LSF:

A vehicle is detected ahead within ACC with

LSF range

– ACC with LSF operates at speeds up to 180 km/h (112 mph).

No vehicle is detected within ACC with LSF range

– ACC with LSF operates at

the speed of 30 km/h (18 mph) or above.

ACC with LSF may not work properly under certain
conditions.

ACC with LSF Conditions and Limitations

P. 576

When not using ACC with LSF: Turn off adaptive
cruise by pressing the

MAIN

button. This also will

turn off the Lane Keeping Assist System (LKAS).

Do not use ACC with LSF under the following
conditions:

•

On roads with heavy traffic or while driving in
continuous stop and go traffic.

•

On roads with sharp turns.

•

On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC with LSF will not apply the brakes to
maintain the set speed.

•

On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or facilities with drive through access.
