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.
 


y Under the following conditions, the LDWS may not be able to detect white or yellow lines
correctly and the LDWS may not operate correctly.
 


y If an object placed on the dashboard is reÀ ected in the windshield and picked up by the
camera.

y The LDWS does not operate until the
system detects a white or yellow line on
either the left or right.
 


y When the system detects a white or
yellow line on one side only, the system
will activate the warning only when the
vehicle deviates on the side where the
white or yellow line is being detected.
 


y The distance and warning sensitivity
(likelihood of a warning) which the
system uses to determine the possibility
of a lane departure can be changed.
  Refer to Personalization Features on
page 9-10 .

Auto cancel
In the following cases, the LDWS cancels
automatically and the LDWS warning
light in the instrument cluster turns on.
 


y The temperature inside the camera is
high or low.
 


y The windshield around the camera is
foggy.
 


y The windshield around the camera is
blocked by an obstruction, causing poor
forward visibility.

For vehicles equipped with the active
driving display, the lane (border lines) is
indicated in the display. The LDWS is
enabled automatically when the operation
conditions are met, and the LDWS
warning light turns off.
Auto cancel warning
When the following operations are
performed, the LDWS determines that
the driver intends to make a lane change
and the LDWS warning is canceled
automatically. The LDWS is enabled
automatically after the driver performs the
operation.
 


y The steering wheel is operated abruptly.



y The brake pedal is depressed abruptly.



y The accelerator pedal is depressed
abruptly.
 


y The turn signal lever is operated (after
the turn signal lever is returned, the
LDWS may not operate for about 3
seconds which is the period of time
required to make a lane correction).

N O T E
After about 60 seconds have elapsed with
the turn signal lever left operating, the
LDWS warning may operate if the vehicle
is close to a white or yellow line.

Canceling the System
Press the LDWS switch to cancel the
LDWS. The LDWS OFF indicator light
turns on.
For vehicles with the active driving
display, the driving lane indication in the
active driving display is not indicated
when the LDWS is cancelled.

LDWS Warning
If the system determines that there is the
possibility of a lane departure, the LDWS
warning beep activates and the LDWS
warning light À ashes. Operate the steering
wheel appropriately and steer the vehicle
to the center of the lane.
For vehicles equipped with the active
driving display, if there is the possibility of
a lane departure, the system indicates the
direction it determines that the vehicle is
deviating in the active driving display.

y If the LDWS warning sound is set to
rumble *1 , the sound will be heard from
the vehicle speaker on the side which
the system determined the vehicle may
be deviating from its lane.
 


y It may be dif¿ cult to hear the LDWS
warning beep depending on the
surrounding conditions such as outside
noise.
 


y The volume of the LDWS warning sound
can be changed.
  Refer to Personalization Features on
page 9-10 .
 


y The type of warning sound (rumble *1 /
beep) on the LDWS can be changed.
  Refer to Personalization Features on
page 9-10 .

*1 A rumble strip is a series of grooves in
the road pavement surface positioned at
speci¿ c intervals, and when the vehicle
passes over it a vibration and rumble
sound is produced which alerts the
driver that the vehicle is departing from
the lane.
  The rumble sound is a reproduction of
the sound which occurs when a vehicle
passes over a rumble strip.

Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis
roller or being towed:
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation when
the vehicle is running on a chassis roller or being towed.
Refer to the Stopping the Smart City Brake Support (SCBS) System Operation on page
4-107 on how to turn off the Smart City Brake Support (SCBS) system.

CAUTION




¾ When driving off -road in areas where there is grass or forage, it is recommended that the
Smart City Brake Support (SCBS) system be turned off .




¾ Always use tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not
operate normally.
 


¾ The laser sensor (front) includes a function for detecting a soiled windshield and informing
the driver, however, depending on the conditions, it may not detect plastic shopping bags,
ice or snow on the windshield. In such cases, the system cannot accurately determine a
vehicle ahead and may not be able to operate normally. Always drive carefully and pay
attention to the road ahead.

*Some models.
 


y The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-infrared
laser beam and receiving the beam reÀ ected off the reÀ ector of the vehicle ahead, and
then using it for the measurement. Consequently, the Smart City Brake Support (SCBS)
may not operate under the following conditions:
 


y ReÀ ection of the laser is poor due to the shape of the vehicle ahead.



y The vehicle ahead is signi¿ cantly dirty.



y Under bad weather condition, such as rain, fog and snow.



y The window washer is being used or the windshield wipers are not used when it's
raining.

y Elongated luggage or cargo is loaded onto installed roof rails and covers the laser
sensor (front).
 


y Exhaust gas from the vehicle in front, sand, snow, and water vapor rising from
manholes and grating, and water splashed into the air.
 


y When towing a malfunctioning vehicle.



y When driving with tires having signi¿ cantly different wear.

vehicle ahead and the Smart City Brake Support (SCBS) system may operate.
 


y Objects on the road at the entrance to a curve.



y Vehicles passing in the opposite lane while making a curve.



y Metal objects, bumps, or protruding objects on the road.



y When passing through a toll gate equipped with a bar.



y When passing under a vinyl curtain or À ag.



y Plastic objects such as pylons.

Rear View Monitor
Viewing the Display
Guide lines which indicate the width of the vehicle (yellow) are displayed on the screen as a
reference to the approximate width of the vehicle in comparison to the width of the parking
space you are about to back into.
Use this display view for parking your vehicle in a parking space or garage.

a

a) Vehicle width guide lines (yellow)
These guide lines serve as a reference to the approximate width of the vehicle.
b) Distance guide lines.
These guide lines indicate the approximate distance to a point measured from the
vehicle's rear (from the end of the bumper).
 

y
 The red and yellow lines indicate the points about 50 cm (19 in) for the red line and
100 cm (39.3 in) for the yellow lines from the rear bumper (at the center point of each
of the lines).

CAUTION
The guide lines on the screen are fi xed lines. They are not synced to the driver's turning
of the steering wheel. Always be careful and check the area to the vehicle's rear and the
surrounding area directly with your eyes while backing up.

Rear View Monitor Operation
The operation of the rear view monitor when reversing the vehicle varies depending on
the traf¿ c, road, and vehicle conditions. The amount of steering and the timing also varies
depending on conditions, so con¿ rm the surrounding conditions directly with your eyes and
steer the vehicle in accordance with the conditions.
Be well aware of the above cautions prior to using the rear view monitor.
