NOTE
 y The Blind Spot Monitoring (BSM) does not operate when the vehicle spee\
d is lower than
about 10 km/h (6.2 mph).
 y The detection area of the Blind Spot Monitoring (BSM) has been determined based on
the lane width of general freeways. Therefore on a road with a narrower lane width, the
system may detect vehicles on a lane next to the adjacent lane and opera\
te the warning
light/beep. On a road with wider lane width, the system may not detect vehicles on the
adjacent lane and may not operate the warning light/beep.
 y Under the following conditions, the system may be unable to detect vehic\
les, or detection
may be delayed.
 y The vehicle accelerates from a standing-start with a vehicle alongside. y A vehicle moves from a lane two lanes over to the adjacent lane. y The difference in vehicle speed between your vehicle and another vehicle is larger
when passing or being passed, and the vehicle passes the detection area within a short
period of time.
 y On a steep incline, or when there is a difference in height between lanes. y Immediately after the system has been activated by pressing the Blind Spot Monitoring
(BSM) OFF switch again after it has been turned off (Blind Spot Monit\
oring (BSM)
OFF indicator light in instrument cluster illuminates) by pressing the switch.
 y(Automatic transaxle vehicles) The shift lever is shifted to the R position, or directly after being shifted from the R
position.
 y The system may not operate normally when towing a trailer. Turn off the system by
operating the Blind Spot Monitoring (BSM) OFF switch when towing a tra\
iler.
 y The system switches to the Rear Cross Traffi c Alert function when the shift lever (Manual
transaxle) or the selector lever (Automatic transaxle) is shifted to \
the R position.

Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible
collision using an indicator and warning sound in the instrument cluster\
while the vehicle
is being driven at about 15 km/h or faster (10 mph or faster) and the \
system's radar sensor
determines that your vehicle may hit a vehicle or obstruction ahead.
WARNING
Do not rely completely on the Forward Obstruction Warning (FOW) system and always
drive carefully: Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of
a collision. The ability to detect an obstruction is limited depending on the obstruction,
weather conditions, or traffi c conditions. Therefore, if the accelerator pedal or brake
pedal is mistakenly operated it could result in an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safe
distance from vehicles ahead or on-coming vehicles.
NOTE
 y  The Forward Obstruction Warning (FOW) system operates when all of the following
conditions are met:
 y The ignition is switched ON. y The Forward Obstruction Warning (FOW) system is on. y The vehicle speed is about 15 km/h (10 mph) or faster. y The relative speed between your vehicle and the vehicle or obstruction ahead \
is about
15 km/h (10 mph) — 145 km/h (90 mph).
 y The Forward Obstruction Warning (FOW) system may not operate under the following
conditions:
 y If there is the possibility of hitting only a part of a vehicle or obstruction \
ahead. y If the vehicle is accelerated rapidly and it comes close to a vehicle ah\
ead. y The DSC is malfunctioning. y The vehicle is driven at the same speed as the vehicle ahead. y The accelerator pedal is depressed. y The brake pedal is depressed. y The steering wheel is being operated. y The selector lever is being operated. y The turn signal is being used.

Lane Departure Warning System (LDWS)
Lane Departure Warning System (LDWS) *
The LDWS notifi es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffi c lane using the Forward Sensing
Camera (FSC). If it determines that the vehicle may be deviating from \
its lane, it notifi es
the driver by fl ashing the LDWS indicator light (green) and operating the LDWS warning\

sound.
Refer to Forward Sensing Camera on page 4-63 .
Use the LDWS when you drive the vehicle on roads with white or yellow li\
nes.

When Driving
Lane Departure Warning System (LDWS)
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.
NOTE
 y If your vehicle deviates from its traffi 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 warni\
ng 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 abr\
uptly and the
vehicle moves close to a white or yellow line, the system determines tha\
t 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 line\
s of the traffi c
lane.
