- The radar sensor's vision can be reduced
or entirely blocked by rain, snow, and
heavy spray. This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the direction you
are traveling and the relevant area
around the vehicle.
- Please note that side assist indicates
there are approaching vehicles, or vehi-
cles in your blind spot, only after your ve-
hicle has reached a driving speed of at
least 19 mph (30 km/h).
- Side ass ist signal does not work around
tight corners (turning radius less than
328 feet or 100 m).
- Side assist is no replacement for the driv-
er's full attention . The driver alone is re-
sponsible for lane changes and similar
driving maneuvers. Always keep an eye
on the direction you are traveling and the
relevant area around the vehicle.
(D Note
- To ensure that you do not adversely af-
fect side assist, do not block the area on
the rear bumper where the radar sensors
are located with foreign objects (such as
stickers or bicycle racks).
- Make sure that the signal light on the
outside m irror is not blocked by st ickers
or other items.
@ Tips
- Side assist automatically deactivates if it
detects that the radar sensors are
blocked
9 page 120. The indicator light
on the button goes out .
- The area on the bumper where the radar
senso rs are located must consistently re-
main free of snow, ice, and heavy soiling
so that side assist can function properly.
Follow the additional notes on
r:!> page 120 .
- Additional tinting on the front side win-
dows can make it harder to see and cor-
rectly understand the signa l light on the
outside mirror.

Sensor detection area
Applies to vehicles: wit h side assist
t
Fig. 13 2 Schemat ic illustrat ion: Sensor detect ion area
The detection¢ fig. 132 of the radar sensor
detection area is made up of:
- the approach area (light red area)
(D, about
230 feet (70 m) behind the vehicle, and
- the "blind spot" (dark red area) @ .
The radar sensors cover the adjacent left and
right lanes. Other lanes are
not covered by the
radar sensors.
(D Tips
Side assist does not measure actual lane
width. The system assumes a fixed lane
width . Detection in the left and right lanes
is based on this assumed lane width .
When driving on narrow roads or when
driving to the left or right of the center of
a travel lane, it is possible that vehicles
will be detected that are
not in the lane
next to the lane you are using
¢ page 119 .
Operation
Applies to vehicles: wit h side assist
Side assist compares the distance and differ-
ence in speed of detected vehicles with the
speed of your vehicle . Whenever the differ -
ence in speed and distance is registered as no·
table if you were to change lanes, a signal
light appears on the respective m irror.
