Collision Mitigation Braking System
TM
(CMBS
TM
)*
Can assist you when there is a possibility of your vehicle colliding with a vehicle
detected in front of yours. The CMBS
TM is designed to alert you when a potential
collision is determined, as well as to reduce your vehicle speed when a collision is
deemed unavoidable to help minimize collision severity.
■How the system works
1 Collision Mitigation Braking System
TM (CMBS
TM)*
Important Safety Reminder
The CMBS
TM 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.
The CMBSTM may not activate or may not detect a
vehicle in front of your vehicle under the following
conditions:
•The distance between your vehicle and the vehicle
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
vehicle ahead of you at high speed.•The vehicle ahead of you is a motorcycle or other
small vehicle.•A vehicle suddenly crosses in front of you.•When you drive on a curved or winding road that
makes it difficult for the sensor to properly detect a
vehicle in front of you.•When there are pedestrians or animals in front of
your vehicle.
A radar sensor starts to monitor if there is a vehicle in front of you when your
vehicle speed is above 10 mph (15 km/h).
The radar sensor is
in the front grille.
The CMBS
TM activates when the speed difference between your vehicle and a
vehicle detected in front of you becomes more than 10 mph (15 km/h) with a
chance of a collision.

The system has four alert stages for a possible collision. However, depending on the circumstances, the CMBS
TM may not go through all of
the stages before initiating the last stage.

Press this button for about one second to turn
on and off the system.
When the CMBS
TM is off:
• The beeper sounds.
• The CMBS
TM indicator in the instrument
panel comes on.
• A message on the multi-information display
reminds you that the system is off.

•You drive off-road or on a mountain road for an
extended period.•You drive with the parking brake applied.•You drive in bad weather (rain, fog, snow, etc.)•The radar sensor cover is blocked by dirt, mud, dry
leaves, wet snow, etc.•An abnormal tire condition is detected (wrong tire
size, flat tire, etc.)
Once the conditions that caused the CMBS
TM to shut
off improve, the system comes back on.

Driving
The CMBS
TM 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 ahead 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.■Through a low bridge at high speed
You drive under a low or narrow bridge at high speed.■Speed bumps, road work sites, train tra cks, roadside objects, etc.
You drive over speed bumps, steel road plates, etc., or your vehicle approaches train
tracks or roadside objects [such as a traffic sign and guard rail] on a curve.■
With Little Chance of a Collision

TM (CMBS
TM)*
Avoid the following conditions that may cause the
radar aim to be temporarily out of range and prevent
the CMBS
TM from working properly.
•A heavy load in the rear or modifications to the
suspension tilts your vehicle.•The tire pressures are not correct, the tire sizes are
incorrect, the tire types are different, and/or the
tires are not in good condition.
For the CMBS
TM to work properly:
Always keep the rada r sensor cover clean.
Never use chemical solvents or polishing powder for
cleaning the sensor cover. Clean it with water or a
mild detergent.
Do not put a sticker on the emblem or replace the
emblem.
Take your vehicle to a dealer if you need the radar
sensor to be repaired, or removed, or the radar
sensor cover is strongly impacted.

Even when the system is on, always confirm if there is
no obstacle near your vehicle before parking.
The system may not work properly when:•The sensors are covered with snow, ice, mud or
dirt.•The vehicle is on uneven surface, such as grass,
bumps, or a hill.•The vehicle has been out in hot or cold weather.•The system is affected by some electronic devices
that generate ul trasonic wave.•Driving in bad weather.
The system may not sense:•Thin or low objects.•Sonic-absorptive materials, such as snow, cotton,
or sponge.•Objects directly under the bumper.
Do not put any accessories on or around the sensors.
