uuWhen Driving uForward Collision Warning (FCW) with Pedestrian Detection
*
Driving
In certain conditions FCW with pedestrian Detection may:
• Not activate, or may not detect a vehicle or pedestrian in front of your vehicle.
• Activate even when you are aware of a vehicle or pedestrian ahead of you, or
when there is no vehicle or pedestrian ahead.
Some examples of these conditions are listed below.■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 reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Roadway objects or structures are misinterpreted as vehicles or pedestrians.
• Reflections on the interior of the front windshield.
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving over bumps.■

■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 vehicle or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bic ycle, 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 and a vehicle in front of you is
significantly large.
• 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 recognizing that the person is a pedestrian.
• When the pedestrian is squatting.
• When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.Limitations applicable to pedestrian detection only

Driving
Lane Departure Warning (LDW)
*
Alerts you when the system determines a possibility of your vehicle unintentionally
crossing over detected lane markings.
If your vehicle is getting too close to detected
left or right side lane markings without a turn
signal activated, LDW will give audible and
visual alerts.
The beeper sounds and the Lane Departure
message appears on the multi-information
display, letting you know that you need to
take appropriate action.
The system begins to search for lane markings when all the following conditions are
met:
• The vehicle is traveling between 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.■
How the System Works
1Lane Departure Warning (LDW)
*
Important Safety Reminder
Like all assistance systems, LDW has limitations.
Over-reliance on LDW may result in a collision. It is
always your responsibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in use. LDW may not detect all
lane markings or lane departures; accuracy will vary
based on weather, speed and lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.

LDW may not activate or may not rec ognize lanes, and may activate even when
keeping in the middle of a lane, under certain conditions. Some examples of these
conditions are listed below.■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 lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interior of the front windshield.■Roadway conditions
• Driving on a snowy or wet roadway (obscured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on a road with temporary lane markings.
• Faint, multiple, or varied lane markings are visible on the roadway due to road
repairs or old lane markings.
• The roadway has merging, split, or crossing lines (e.g., such as at an intersection
or crosswalk).

Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicle control. The system does
not work if you take your hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 113
LKAS only alerts you when lane drift is detected
without a turn signal in use. LKAS may not detect all
lane markings or lane departures; accuracy will vary
based on weather, speed, and lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions: 2 LKAS Conditions and Limitations P. 384

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 multi-information display
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.
