i-ACTIVSENSE
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sensors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to assist the driver in safer driving by reducing the load on the
driver and helping to avert collisions or reduce their severity. However, because each system
has its limitations, always drive carefully and do not rely solely on the systems.

To Operate the System
The High Beam Control System (HBC)
operates to switch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and high beam position.
The High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area. At the
same time, the High Beam Control System
(HBC) indicator light (green) in the
instrument cluster illuminates.



N O T E
 


y When the vehicle speed is 30 km/h
(18 mph) or higher, the headlights

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.

When Driving
i-ACTIVSENSE
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.
