rely completely on the system and
always stay on course using the
steering wheel.
 The LDWS is not designed to
compensate for a driver’s lack of
caution and relying on the system
could lead to an accident.

Driver Attention Alert(DAA)
*
The DAA is a system that detects the
driver fatigue and decreased
attentiveness based on various types of
vehicle information, and encourages
the driver to take a rest using a screen
display and warning sound.
Warnings and Cautionsfor Using the Driver
Attention Alert (DAA)
WARNING
Do not rely completely on the DAA.
The DAA does not prevent driver
fatigue or decreased attentiveness 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 correctly detect driver fatigue
or decreased attentiveness depending
on the road and driving conditions.
The driver must take sufficient rest in
consideration of safe driving.

Cruising & Traffic Support(CTS)
*
The CTS is a system that reduces the
load on the driver while the vehicle is
driven on expressways or highways.
The CTS has the following 2 functions.
Constant speed/Headway control
function
The function performs headway
control to maintain the distance with a
vehicle ahead at a constant preset
speed without you having to depress
the accelerator or brake pedal.
Steering wheel assist function
When vehicle lane lines are detected,
the function assists your steering wheel
operation to follow the vehicle lane
lines.
When vehicle lane lines are not
detected, the function assists your
steering wheel operation to follow the
trajectory of the vehicle ahead.
Warnings and Cautionsfor Using Cruising &
Tra ffi c Support (CTS)
WARNING
Do not rely completely on the CTS.

The CTS is not an automated driving
system. Therefore, the function has
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 the vehicle ahead
applies the brakes suddenly or
another vehicle cuts into your lane,
which could result in an accident.
Do not use the CTS under the
following conditions. Otherwise, it
may result in an accident.
 The vehicle is driven on roads other
than expressways and highways.
 The vehicle is driven on roads with
sharp curves or with heavy
traffic
where sufficient distances between
vehicles cannot be kept.
 The vehicle is driven on roads where
acceleration and deceleration are
frequently repeated.
 The vehicle is exiting the main lane
on an expressway to enter an
interchange, a rest area, or a parking
area.
