Blind Spot Information System
When the system detects vehicles approach ing from behind in adjacent lanes, the
appropriate indicator comes on, providin g assistance when you change lanes.
The system activates when your vehicle is moving forward at about 20 mph (32 km/h)
or above.
Alert zone range
A: Approx. 1.6 ~ 10 feet (0.5 ~ 3 meters) from vehicle side.
B: Approx. 10 feet (3 meters) from rear bumper.
C: Approx. 10 ~ 82 feet (3 ~ 25 meters) behind from rear bumper. (The faster the
approaching vehicle, the further away it will be detected.)
The initially set alert zone is alert zone 1. Over time, after the vehicle has been driven
on straight roads with traffic and roadside objects, the system will adapt and expand
the alert zone (alert zone 1 and 2).
■How the System works
1 Blind Spot Information System
Important Safety Reminder
Like all assistance systems, the blind spot information
system has limitations. Always look in your mirrors, to
either side of your vehicle, and behind you for other
vehicles before changing la nes. Overreliance on the
blind spot information sy stem may result in a
collision.
Have your vehicle checked by a dealer in the
following situations:
•The rear bumper or area around the radar sensors
is strongly impacted.
•The indicator does not come on even if a vehicle in
the alert zone should have been detected.
•The rear bumper or any system components need
to be repaired.
If the rear bumper or any system components are
repaired, the system will re vert to alert zone 1 only
until it is able to adapt and expand to alert zone 1
and 2.
Turn the system off when towing a trailer.
The system may not work properly for the following
reasons:
•The added mass tilts the vehicle and changes the
radar coverage.
•The trailer itself can be detected by the radar
sensors, causing the blind spot information system
alert indicators to come on.

rear bumper corners : Alert zone 1
A BC : Alert zone 2

If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by pressing the
button and take your vehicle to a dealer.
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehi cle checked by a dealer:
•The vehicle mounted onto a bump, curb, chock,
embankment, etc.
•You drive the vehicle where water is deep.
•Your vehicle has a frontal collision.
