▼ Camera and Sensors
Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) detects lane indications and recognizes headlights,
taillights and city lights during nighttime drivin
g. In addition, it also detects the vehicle
ahead, pedestrians, or obstructions. The following systems also use the Forward Sensing
Camera (FSC).
High Beam Control System (HBC)
Driver Attentio n Alert (DAA)
Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS)
Traffic Jam Assist (TJA)
Traffic Sign Recognition System (TSR)

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes by notifying the driver of the presence of vehicles
approaching from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while traveling in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and notifies the driver by turning on the
BSM warning indicator light and displaying th e vehicle detection screen (vehicles with
instrument cluster (Type A/B) and active driving display).
If the turn signal lever is operated to si gnal a turn in the direction in which the BSM
warning indicator light is illuminated while the approaching vehicle is detected, the BSM
notifies the driver of possible danger by tu rning on the BSM warning indicator light, and by
activating the warning sound and the warning screen indicator display (vehicles with
instrument cluster (Type A/B) and active driving display).
The detection area on this system covers the driving lanes on both sides of the vehicle and
from the rear part of the front doors to about 50 m (164 ft) behind the vehicle.

WA R N I N G
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a
lane change. Due to certain limitations with
the operation of this system, the BSM warning
indicator light, the warning sound and the warn ing screen indicator display may not activate
or they might be delayed even though a vehicle is in an adjacent driving lane. Always make it
your responsibility as a driver to check the rear.

Traffic Jam Assist (TJA)*
The TJA is a system which consists of a headway control function and a steering assist
function for reducing driver fatigue during traffic jams when driving on expressways or
highways.
This system performs headway control to maintain a constant distance between your vehicle
and a vehicle ahead at a preset vehicle speed without you having to use the accelerator or
brake pedal. Even further, with the steering assist function, when vehicle lane lines are
detected, the function assists the driver in k eeping the vehicle within the lane lines. If lane
lines are not detected, the function provides th e driver driving assistance in keeping the
vehicle along the motion path with the vehicle ahead.
WA R N I N G
Do not rely completely on TJA:
 The TJA is not an automated driving system. In addition, the functions have limitations. Do
not rely completely on the system and always stay on course using the steering wheel.
 Set a vehicle speed within the speed limit acco rding to the road conditions and the weather
conditions.
 The TJA may not be able to detect a vehicle ahead depending on the type of vehicle ahead
and its conditions, the weather conditions, and the road conditions. Add\
itionally, the
system might be unable to decelerate suffic iently if a vehicle ahead applies the brakes
suddenly, another vehicle cuts into the driving lane, or the difference in vehicle speed
between your vehicle and the vehicle ahead is larger, which could result in an accident.
Check the surrounding conditions and always drive carefully while keeping a safe distance
from vehicles ahead and on-coming vehicles.

For the purposes of safety, switch the TJA off when it is not being used.
Leaving the TJA turned on when it is not in us e is dangerous as it could operate unexpectedly,
resulting in an accident.

Do not use the TJA under the following conditions. Otherwise, it may result in an accident.
 General roads other than expressways or high ways (Driving under these conditions using
the TJA is not possible.)
 Roads with sharp curves and where vehicle tr affic is heavy with insufficient space between
vehicles, or roads where frequent and repet itive acceleration and deceleration occur
(Driving under these conditions using the TJA is not possible).

indication is displayed and h eadway control is performed.

Steering assist function
When lane lines are detected, the function assists the driver in keeping the vehicle within the
lane lines. If lane lines are not detected, th e function provides the driver driving assistance
in keeping the vehicle along the motion path with the vehicle ahead.
