qTo 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. At the same time,
the High Beam Control System (HBC)
indicator light (green) in the instrument
cluster illuminates.
The High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area.
NOTE
lWhen the vehicle speed is 30 km/h (18 mph)
or higher, the headlights automatically
switch to high beams when there are no
vehicles ahead or approaching in the
opposite direction.
When the vehicle speed is less than about
20 km/h (12 mph), the High Beam Control
System (HBC) switches the headlights to
low beams.
lThe low beams may not switch to high
beams when cornering.
lOperation of the High Beam Control
System (HBC) function can be disabled
Refer to Personalization Features on page
9-10.

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.

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.
ØDriving on roads with tight curves.
ØDriving 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.

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
highway.
lThe white or yellow lines are less visible because of dirt or paint flaking.lThe vehicle ahead is running near a white or yellow line and the line is less visible.lA white or yellow line is less visible because of bad weather (rain, fog, or snow).lA misleading line is picked up on the road such as a temporary line for construction, or
because of shade, lingering snow, or grooves filled with water.
lThe surrounding brightness suddenly changes such as when entering or exiting a tunnel.lThe illumination of the headlights is weakened because of dirt or the optical axis is deviated.lThe windshield is dirty or foggy.lBack-light is reflecting from the road surface.lThe road surface is wet and shiny after rain, or there are puddles on the road.lThe shade of a guardrail parallel to a white or yellow line is on the road.lThe width of a lane is excessively narrow or wide.lThe road is excessively uneven.lThe vehicle is shaken after hitting a road bump.lThere are two or more adjacent white or yellow lines.lThere are various road markings or lane markings of various shapes near an intersection.
