Warnings and Cautions
for Using the Emergency Lane Keeping (ELK)
WARNING
Do not rely completely on the ELK.
The ELK has limitations. Do not rely
completely on the system and always
stay on course using the steering
wheel.
 The ELK is not an automated driving
system. Over reliance on the system
could lead to an accident.
 The detection range of the camera
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 ELK 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.
 (Blind Spot Assist)
The vehicle is driven on roads other
than expressways and highways.
 (Blind Spot Assist and Head-on
traffic avoidance assist)
The rear bumper around a rear side
radar sensor is deformed.
