When Driving
i-ACTIVSENSE
Lane Departure Warning System (LDWS)
T h e L D W S n o t i¿ 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). If it determines that the vehicle may be deviating from its lane, it noti¿ es
the driver by À ashing the LDWS indicator light (green) and operating the LDWS warning
sound.
Refer to Forward Sensing Camera on page 4-111 .
Use the LDWS when you drive the vehicle on roads with white or yellow lines.


Forward Sensing Camera (FSC)
LDWS warning light (Amber)/
LDWS indicator light (Green)

The warning light À ashes when the system has a malfunction.
Refer to Warning Lights on page 4-21 .
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.

CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.

N O T E
 


y If your vehicle deviates from its traf¿ c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the center of the lane.
 


y When the turn signal lever is operated for a lane change, the LDWS warning is
automatically canceled. The LDWS warning becomes operable when the turn signal lever
is returned and the system detects the white or yellow lines.
 


y If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white or yellow line, the system determines that the driver is
making a lane change and the LDWS warning is automatically canceled.
 


y The LDWS may not operate during the period immediately after the vehicle has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time.
 


y The LDWS does not operate if it does not detect the white or yellow lines of the traf¿ c
lane.

Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible
collision using an indicator and warning sound in the instrument cluster while the vehicle
is being driven at about 15 km/h or faster (10 mph or faster) and the system's radar sensor
determines that your vehicle may hit a vehicle or obstruction ahead.

WARNING
Do not rely completely on the Forward Obstruction Warning (FOW) system and always
drive carefully:
Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of
a collision. The ability to detect an obstruction is limited depending on the obstruction,
weather conditions, or traffi c conditions. Therefore, if the accelerator pedal or brake
pedal is mistakenly operated it could result in an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safe
distance from vehicles ahead or on-coming vehicles.
