▼When the System Operates
1. The system goes on operation standby
when the LDWS switc h is pressed and
the LDWS OFF indica tor light in the
instrument cluster turns off.
2. Drive the vehicle in the center of the
driving lane while the LDWS OFF
indicator light is turned off. The
system becomes operational when all
of the following conditions are met.
The vehicle is driven in the center of
the driving lane with the white or
yellow lines on the left and right
sides, or on either side.
The vehicle speed is 70 km/h (44
mph) or faster.
The vehicle is driven on a straight
road or road with gentle curves.
The LDWS does not operate in the
following cases:
The system cannot detect white or
yellow lines.
The vehicle speed is less than 65
km/h (40 mph).
The vehicle is making a sharp turn.
The vehicle is making a curve at an
inadequate speed.
NOTE
The LDWS does not operate until the
system detects a white or yellow line on
either the left or right.
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.
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 9-9.
Auto cancel
In the following cases, the LDWS cancels
automatically and the LDWS warning
light in the instrument cluster turns on.
The temperature inside the camera is
high or low.
The windshield around the camera is
foggy.
The windshield around the camera is
blocked by an obstruction, causing poor
forward visibility.
The LDWS is enabled automatically when
the operation conditions are met, and the
LDWS warning light turns off.
Auto cance l 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.
The steering wheel is operated abruptly.

The brake pedal is depressed abruptly.
The accelerator pedal is depressed
abruptly.
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).
NOTE
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.
Vehicle lane display (vehicles with
multi-information display)
The vehicle lane lines are no longer
indicated in the multi
-information display
when the LDWS is canceled.
NOTE
When the ignition is switched OFF, the
system status before it was turned off is
maintained. For example, if the ignition is
switched OFF with the lane-keep system
operable, the system will be operable
when the ignition is switched ON the next
time.
▼ 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 flashes. Operate the steering
wheel appropriately and steer the vehicle
to the center of the lane.
For vehicles equipped with the
multi-information display and the active
driving display, the color of the lane line
in the direction which the system
determined that the vehicle may be
deviating from its lane changes from white
to amber and the vehicle lane line flashes.
Indication on display

NOTE
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.
It may be difficult to hear the LDWS
warning beep depending on the
surrounding conditions such as outside
noise.
The volume of the LDWS warning sound
can be changed.

Refer to Personalization Features on
page 9-9.
*1 A rumble strip is a series of grooves in
the road pavement surface positioned
at specific 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.

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes by alerting the driver to the pr esence of vehicles approaching
from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while travel ing in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and turns o n the BSM warning lights
equipped on the door mirrors depending on the conditions. If th e turn signal lever is
operated to signal a lane change in the direction in which the BSM warning light is
illuminated, the system warns the driver of a vehicle in the detection area by flashing the
BSM warning light and activating a beep sound.
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the doors to about 50 m (164 ft) behind t he vehicle.
Detection areas Your vehicle
WA R N I N G
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a
lane change. Due to certain limitations with the operation of this system, the BSM warning
light may not flash or it might be delayed even th ough a vehicle is in an adjacent driving lane.
Always make it your responsibility as a driver to check the rear.

Warning Beep
The BSM or Rear Cross Traffic Al ert (RCTA) system notifies the driver of the presence of
vehicles in adjacent lanes to the rear of your vehicle using th e BSM warning lights and the
warning beep while the s ystems are operational.
BSM warning lights
The BSM warning lights are equi pped on the left and right door mirrors. The warning lights
turn on when a vehicle approaching from the rear in an adjacent lane is detected.
When the ignition is switched ON, the malfunction warning light turns on momentarily and
then turns off after a few seconds.
Forward driving (BSM system operation)
The BSM system detects vehicles approaching from the rear and t urns on the BSM warning
lights equipped on the door mirrors according to the conditions . Additionally, while a BSM
warning light is illuminated, if the turn signal lever is operated to signal a turn in the
direction in which the BSM warni ng light is illuminated, the BSM warning light flashes.
Reverse driving (Rear Cross Traf fic Alert (RCTA) system operation)
The Rear Cross Traffic Alert (RCTA) system detects vehicles app roaching from the left and
right of your vehicle and flashes the BSM warning lights.
Function for cancelling illumination dimmer
If the BSM warning lights turn on when the parking lights are turned on, the brightness of
the BSM warning lights is dimmed.
If the BSM warning lights are d ifficult to see due to glare from surrounding brightness when
traveling on snow-covered roads or under foggy conditions, pres s the dimmer cancellation
button to cancel the dimmer and increase the brightness of BSM warning lights when they
turn on.
