■The Automatic High Beam can be operated when
The power switch is in ON mode.
■ Camera sensor detection information
●High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another
• When oncoming or preceding vehicles are hidden from sight due to
repeated curves, road dividers or roadside trees
• When oncoming vehicles appear from the faraway lane on wide road
• When oncoming or preceding vehicles have no lights
● High beam may be turned off if an oncoming vehicle that is using fog lights
without using the headlights is detected.
● House lights, street lights, red traffic signals, and illuminated billboards or
signs may cause the high beam to turn off.
● The following factors may affect the amount of time taken to turn high beam
on or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and
preceding vehicles
• The movement and direction of oncoming and preceding vehicles
• When a oncoming or preceding vehicle only has operational lights on one side
• When a oncoming or preceding vehicle is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
● High beam may be turned on or off when unexpected by the driver.

WARNING
■Conditions under which the vehicle-to-vehicle distance control may
not function correctly
Apply the brakes (or accelerator pedal) as necessary in the following condi-
tions as the radar sensor may not be able to correctly detect vehicles
ahead, and a fatal or serious accident may result:
● When the vehicle ahead of you decelerates suddenly
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
●When the road curves or when the
lanes are narrow
● When steering wheel operation or your
position in the lane is unstable

4-5. Using the driving support systems
When the system judges that the vehicle is deviating from the current
traffic lane, an alert buzzer sounds and it prompts cautions from the
display screen of the multi-information display.
When the alert buzzer sounds, please check the surrounding road situa-
tion and return near the center of the white (yellow) lane markers by safely
operating the steering wheel.
Press the LDA switch to activate
the LDA.
LDA indicator will come on and
lane lines will be displayed on the
multi-information display.
Press the switch again to deacti-
vate the LDA.
The LDA will remain on or off even
if the power switch is turned off.

WARNING
■Before using the LDA
Do not over rely on the LDA. The LDA does not drive the vehicle automati-
cally, nor does it reduce the amount of care you need to take. As such, the
driver must always assume full responsibility for understanding his/her sur-
roundings, for operating the steering wheel to correct the driving line, and
for driving safely. Also, take occasional rests from fatigue due to driving over
long periods of time, etc.
Inappropriate or negligent driving could lead to an unexpected accident.
■ To avoid operating the LDA by mistake
Switch the LDA off using the LDA switch when not in use. ( P. 226)
■ Situations unsuitable for LDA
Do not use the LDA in any of the following situations.
Otherwise, the system may not function correctly and could result in an
accident.
● When driving with tire chains, a spare tire, or similar equipment
● When there are objects or structures along the roadside that might be mis-
interpreted as lane markers (such as guardrails, a curb, reflector posts,
etc.)
● When driving on snowy roads
● When pavement lane markers are difficult to see due to rain, snow, fog,
sand, dirt, etc.
● When there are visible lines on the pavement from road repairs, or if the
remains of old lane markers are still visible on the road
● When driving through construction areas

WARNING
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to visually check all
around the vehicle both directly and using the mirrors before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes
● In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to visually check
all around the vehicle both directly and using the mirrors before proceed-
ing.
● If the tire sizes are changed, the position of the fixed guide lines displayed
on the screen may change.
● The camera uses a special lens. The distances between objects and
pedestrians that appear in the image displayed on the screen will differ
from the actual distances. ( P. 236)

4-5. Using the driving support systems
Driving assist systems
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to redu ce the amount of effort needed to
turn the steering wheel
◆Enhanced VSC (Enhanced Ve hicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional st ability when swerving on slippery
road surfaces by controllin g steering performance.
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.
