rarely controls the steering wheel, when
the vehicle drives well inside the lanes.
However, it starts to control the steering
wheel, when the vehicle is about to
deviate out of the lanes.
Lane Departure Warning
LDW alerts the driver with a visual
warning and a warning alarm when the
system detects the vehicle departing
the lane. The steering wheel will not be
controlled.LKA system operation

vehicle from crossing the lane maker
in below conditions.
- Vehicle speed is over 64 km/h (40 mph)
- The system detects both lane markers
- When driving, the vehicle is located between both lanes normally.
- The steering wheel is not turned suddenly.
When lanes are detected and all the
conditions to activate LKA system are
satisfied, LKA system indicator light (

Keep hands on steering wheel
If the driver takes their hands off the
steering wheel for several seconds while
LKA system is activated, the system will
warn the driver.
Information
If the steering wheel is held very lightly
the message may still appear because LKA
system may not recognize that the driver
has their hands on the wheel.

late according to road conditions.
Therefore, always have your hands on
the steering wheel while driving.

WARNING
• The warning light on the side view
mirror will illuminate whenever a
vehicle is detected at the rear side by
the system.
To help avoid accidents, do not focus
only on the warning light and neglect
to see the surrounding of the vehicle.
• Drive safely even though the
vehicle is equipped with Blind-Spot
Collision-Avoidance Assist system.
Do not solely rely on the system
but check your surrounding before changing lanes or backing the
vehicle up.
• The system may not alert the driver
in some conditions so always check
your surroundings while driving.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not the
warning light on the side view mirror
illuminates or there is a warning alarm.
• Playing the vehicle audio system at
high volume may offset the Blind-
Spot Collision Warning system
warning sounds.
• The warning of Blind-Spot Collision-
Avoidance Assist system may not
sound while other system’s warning sounds. Blind-Spot Collision-Avoidance
Assist
Blind-Spot Collision-Avoidance Assist
system may apply braking power, when
an approaching vehicle is detected
within a certain distance next to or
behind your vehicle.
It gently applies braking power on the
wheel, which is located in the opposite
side of the possibly-colliding point. The
instrument cluster will inform the driver
of the system activation.
Blind-Spot Collision-Avoidance Assist
system is automatically deactivated when:
- The vehicle drives a certain distance away
- The vehicle direction is changed against the possible-colliding point
- The steering wheel is abruptly moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in the
middle of the vehicle lanes to keep the
system in the ready status.
When the vehicle drives too close to one
side of the vehicle lanes, the system may
not properly operate.
In addition, the system may not properly
control your vehicle in accordance with
driving situations. Thus, always pay close
attention to road situations.
