▼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
notifying the driver of the presence of
vehicles approaching
from the rear in an
adjacent lane.
BSM operation
The BSM detects vehicles approaching
from the rear while traveling in the
forward direction at a speed of 10 km/h
(6.3 mph) or faster and notifies the driver
by turning on the BSM warning indicator
light and displaying the vehicle detection
screen.
If the turn signal lever is operated to signal
a turn in the direction in which the BSM
warning indicator light is illuminated
while the approaching vehicle is detected,

Do not rely completely on DAA and always
drive carefully:
The DAA detects driver fatigue and
decreased attentiveness and encourages
the driver to take a rest, however, it is not
designed to prevent the vehicle from
straying. If you rely too much on the DAA it
could lead to an accident. Drive carefully
and operate the steering wheel
appropriately.
In addition, the system may not be able to
detect driver fatigue and decreased
attentiveness correctly depending on the
traffic and driving conditions. The driver
must take sufficient rest in order to drive
safely.

Do not rely completely on the DM and
always drive carefully.
The DM is a system which detects driver
fatigue and sleepiness, and encourages the
driver to take a rest. This is not designed to
prevent driver fatigue and sleepiness, and
over-reliance on the system could lead to
an accident. Drive carefully and turn the
steering wheel appropriately.
In addition, the system may not be able to
detect driver fatigue and sleepiness
correctly depending on the traffic and
driving conditions. The driver must take
sufficient rest in order to drive safely.
Operation conditions
The DM begins monitoring after 20
minutes have passed since the driver
began driving the vehicle and when the
vehicle speed is about 5 km/h (3 mph) or
faster.
NOTE
If the vehicle speed decreases to less
than about 5 km/h (3 mph) while the DM
is monitoring, the DM stops monitoring
for 6 minutes even if the vehicle speed
returns to about 5 km/h (3 mph) or
faster.
If the driver monitoring camera does not
recognize the driver correctly, the DM
may not monitor correctly.
Refer to Driver Monitoring Camera on
page 4-209.
After the DM has displayed the first
message encouraging the driver to take
a rest, it does not display it again during
the following periods.
After displaying the warning pattern
(caution), the next warning pattern
(caution) is not displayed until 45
minutes have passed.
After displaying the warning pattern

Cruising & TrafficSupport (CTS)
*
▼ Cruising & Traffic Support (CTS)
The CTS is a system which consists of a
headway control function and a steering
assist function for reducing driver fatigue
when driving on expressways or
highways.
The system performs headway control to
maintain a constant distance between your
vehicle and a vehicle ahead at a preset
vehicle speed without you having to use
the accelerator or brake pedal. Even
further, with the steering assist function,
when vehicle lane lines are detected, the
function assists the driver in keeping the
vehicle within the lan
e lines. If lane lines
are not detected, the function provides the
driver driving assistance in keeping the
vehicle along the motion path with the
vehicle ahead.
WA R N I N G
Do not rely completely on CTS
The CTS is not an automated driving
system. In addition, the functions have
limitations. Do not rely completely on the
system and always stay on course using
the steering wheel.
Set a vehicle speed within the speed limit
according to the road conditions and the
weather conditions.
The CTS may not be able to detect a
vehicle ahead depending on the type of
vehicle ahead and its conditions, the
weather conditions, and the road
conditions. Additionally, the system
might be unable to decelerate sufficiently
if a vehicle ahead applies the brakes
suddenly, another vehicle cuts into the
driving lane, or the difference in vehicle
speed between your vehicle and the
vehicle ahead is larger, which could
result in an accident. Check the
surrounding conditions and always drive
carefully while keeping a safe distance
from vehicles ahead and on-coming
vehicles.
While the CTS is in use, any intended
engine braking does not occur even if
you shift the shift lever (manual
transmission) or the selector lever
(automatic transmission). If deceleration
is required, lower the vehicle speed
setting or depress the brake pedal.
For the purposes of safety, switch the CTS
off when it is not being used.
Do not use the CTS under the following
conditions. Otherwise, it may result in an
accident.
General roads other than expressways or
highways (Driving under these
conditions using the CTS is not possible.)
Roads with sharp curves and where
vehicle traffic is heavy with insufficient
space between vehicles. Roads where
frequent and repetitive acceleration and
deceleration occur (Driving under these
conditions using the CTS is not possible).

Steering assist function
When lane lines are detected, the function
assists the driver in keeping the vehicle
within the lane lines. If lane lines are not
detected, the function provides the driver
driving assistance in keeping the vehicle
along the motion path with the vehicle
ahead.
NOTE
