i-ACTIVSENSEí
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 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.

High Beam Control System (HBC)í
The High Beam Control System (HBC) determines the conditions in front of the vehicle
using the Forward Sensing Camera (FSC) while driving in darkness to automatically
switch the headlights between high and low beams.
Refer to Warning/Indicator Lights on page 4-20.
While driving the vehicle at a speed of about 30 km/h (18 mph), the headlights are
switched to high beams when there are no vehicles ahead or approaching in the opposite
direction.
The system switches the headlights to low beams when one of the following occurs:
lThe system detects a vehicle or the headlights/lights of a vehicle approaching in the
opposite direction.
lThe vehicle is driven on roads lined with streetlamps or on roads in well-lit cities and
towns.
lThe vehicle is driven at less than about 20 km/h (12 mph).
Forward Sensing
Camera (FSC)
The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.
The warning light illuminates or flashes when the system has a malfunction.
Refer to Warning/Indicator Lights on page 4-20.
CAUTION
ØDo not adjust the vehicle height, modify the headlight units, or remove the
camera, otherwise the system will not operate normally.
ØDo not rely excessively on the High Beam Control System (HBC) and drive the
vehicle while paying sufficient attention to safety. Switch the headlights between

Lane Departure Warning System (LDWS)í
The LDWS system notifies the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffic lane using the forward sensing
camera and if it determines that the vehicle may be deviating from its lane, it notifies the
driver using the multi-information display (vehicles with type A instrument cluster), and by
flashing the LDWS warning light (vehicles with type B instrument cluster) 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 (FSC) on page 4-134.

NOTElIf your vehicle deviates from its traffic lane, the LDWS operates (warning sound and indicator
light). Steer the vehicle adequately to drive the vehicle to the center of the lane.
lWhen 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.
lIf 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.
lThe 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.
lThe LDWS does not operate if it does not detect the white or yellow lines of the traffic lane.lUnder the following conditions, the LDWS may not be able to detect white or yellow lines
correctly and the LDWS may not operate correctly.
lIf an object placed on the dashboard is reflected in the windshield and picked up by the
camera.
lHeavy luggage is loaded in the luggage compartment or on the rear seat and the vehicle is
inclined.
lThe tire pressures are not adjusted to the specified pressure.lWhen the vehicle is driven on the entry and exit to or from the rest area or tollgate of a
