Emergency Lane Keeping(ELK)
*
▼Emergency Lane Keeping (ELK)
The ELK is a system designed to assist
the driver’s steering wheel operation to
avoid danger.
The ELK consists of the Blind Spot
Assist function to prevent your vehicle
from colliding with vehicles on
adjacent lanes, and the Road Keep
Assist function to prevent your vehicle
from deviating from the road.
Refer to Blind Spot Assist on page
4-141.
Refer to Road Keep Assist on page
4-144.
▼
Blind Spot Assist*
The Blind Spot Assist
function assists
the driver in avoiding collisions with
vehicles in adjacent lanes (excluding
vehicles approaching in the opposite
direction).
The Blind Spot Assist function detects
white lines (yellow lines) on the vehicle
lane using the Forward Sensing Camera
(FSC) and detects vehicles on adjacent
lanes using the rear side radar sensors.
If there is a possibility of a collision
with a vehicle in an adjacent lane
when you try to change lanes or if you
may deviate from your lane, it assists
your steering wheel operation to keep
you in the driving lane.
When the steering wheel operation
assist operates, a warning sound and
warning indications on displays alert
the driver of the possibility of a
collision. Furthermore, if the possibility
of a collision increases, a warning
sound and display indications alert the
driver of the danger.
WARNING
Do not rely completely on the Blind
Spot Assist function and always drive
carefully:
 The Blind Spot Assist function has
limitations. Do not rely completely
on the system and always stay on
course using the steering wheel.
 The Blind Spot Assist function is not
an autonomous driving system. In
addition, the system is not designed
to compensate for a driver’s lack of
caution, and over-reliance on the
system could lead to an accident.

and sensors is limited. If the steering
wheel operation assist is operated
without detecting a two-wheeled
vehicle near the detecting vehicle, it
could result in an accident.
Do not use the system under the
following conditions. Otherwise, it
may result in an accident:
The vehicle is driven on slippery
roads such as icy roads,
snow-covered roads, and unpaved
roads.
 Tires other than the specified size are
used, such as when tire chains or
temporary spare tires are used.
 The vehicle is towing a camping
trailer or boat trailer.
 The vehicle is driven on roads other
than expressways and highways.
 The rear bumper around a rear side
radar sensor is deformed.
