Lane Departure Warning System (LDWS) *
The LDWS system noti¿ es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traf¿ c lane using the Forward Sensing
Camera (FSC) and if it determines that the vehicle may be deviating from its lane, it noti¿ es
the driver using the active driving display (vehicles with active driving display), and by
À ashing the LDWS warning light and activating the LDWS warning beep.
Use the LDWS when you drive the vehicle on roads with white or yellow lines.
Refer to Forward Sensing Camera on page 4-111 .


Forward Sensing Camera (FSC)
LDWS warning light

The warning light illuminates when the system has a malfunction.
Refer to Warning Lights on page 4-25 .
WARNING
Do not use the LDWS under the following conditions:
The system may not operate adequately according to the actual driving conditions,
resulting in an accident.
 


¾ Driving on roads with tight curves.



¾ Driving under bad weather conditions (rain, fog, and snow).

The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver’s lack of caution and if you rely too much on the
LDWS it could lead to an accident. The driver is responsible for assuring lane changes and
other maneuvers. Always pay attention to the direction in which the vehicle is traveling
and the vehicle’s surroundings.

Blind Spot Monitoring (BSM) *
The Blind Spot Monitoring (BSM) is designed to assist the driver in checking the area to the
rear of the vehicle on both sides during lane changes by alerting the driver to the presence of
vehicles approaching from the rear in an adjacent lane.
The Blind Spot Monitoring (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 turns on the
Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors depending on
the conditions. If the turn signal lever is operated to signal a lane change in the direction
in which the Blind Spot Monitoring (BSM) warning light is illuminated, the system warns
the driver of a vehicle in the detection area by À ashing the Blind Spot Monitoring (BSM)
warning light and activating a beep sound.
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.

Detection areas Your vehicle

WARNING
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
Blind Spot Monitoring (BSM) warning light may not fl ash or it 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.
