Driving
Blind Spot Information (BSI) System
*
Is designed to detect vehicles in specified alert zones adjacent to your vehicle,
particularly in harder to see areas common ly known as “blind spots.”
When the system detects vehicles approaching from behind in adjacent lanes, the
appropriate indicator comes on for a few seconds, providing assistance when you
change lanes.■How the system works
1 Blind Spot Information (BSI) System
*
Important Safety Reminder
Like all assistance systems, BSI has limitations. Over
reliance on BSI may result in a collision.
The system is for your convenience only. Even if an
object is within the alert zone, the following
situations may occur.•The BSI alert indi cator may not come on due to
obstruction (splashes, etc.) even without the Blind
Spot Not Available MID appearing.•The BSI alert indicator may come on even with the
message appearing.
The BSI alert indicator may not come on under the
following conditions:•A vehicle does not stay in the alert zone for more
than two seconds.•A vehicle is parked in a side lane.•The speed difference between your vehicle and the
vehicle you are passing is greater than 6 mph (10
km/h).•An object not detected by the radar sensors
approaches or passes your vehicle.

WARNING
Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on the blind spot
information system when changing lanes.
Always look in your mirrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.

Turn the system off when towing a trailer.
The system may not work properly for the following
reasons:•The added mass tilts the vehicle and changes the
radar coverage.•The trailer itself can be detected by the radar
sensors, causing the BSI alert indicators to come on.
BSI may be adversely affected when:•Objects (guard rails, poles, trees, etc,.) are
detected.•An object that does not reflect radio waves well,
such as a motorcycle, is in the alert zone.•Driving on a curved road.•A vehicle is moving from a far lane to the adjacent
lane.•The system picks up external electrical interference.•The rear bumper or the sensors have been improperly
repaired or the rear bumper has been deformed.•The orientation of the sensors has been changed.•In bad weather (Heavy rain, snow, and fog).
For proper BSI use:•Always keep the rear bumper corner area clean.•Do not cover the rear bumper corner area with
labels or stickers of any kind. •Take your vehicle to a dealer if you need the rear
bumper corner area or the radar sensors to be repaired,
or the rear bumper corner area is strongly impacted.

to overtake you with a speed difference of
no more than 31 mph (50 km/h) from your

of no more than 12 mph (20 km/h).

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 a 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 vehicl e in front of you when your
vehicle speed is above about 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 about 10 mph (15 km/h) with
a chance of a collision.

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 trac ks, 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.■

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 radar 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.
