Driver assistance

Warning stage
If you activate a turn signal and the display flash-
es, side assist is warning about objects that have
been classified as critical.
Depending on the vehicle equipment and other
driver assistance systems, the display may also
flash if you have not activated a turn signal. If
you are approaching a detected lane marker line
and it appears you will be leaving the lane, the
display will warn you about detected vehicles
that are classified as critical. You can also be
warned with corrective steering > page 176,
Lane departure warning.
Detection range
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
may turn on even though there is no vehicle lo-
cated in the area that is critical for a lane change.
For example:
— If the lanes are narrow or if you are driving on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another
lane that is not adjacent to your current lane.
— If you are driving through a curve. Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
— If side assist reacts to other objects (such as
roadside structures like guard rails).

ZA\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 150.
— The display may not appear on time when
vehicles are approaching or being passed
very quickly.

@ Tips
— If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor-
rect.
— The coverage areas of the sensors > fig. 132
are diagrams and do not represent a true-
to-scale image of the sensor ranges.
— The system complies with United States FCC
regulations and ISED regulations
> page 341.
Adjusting side assist

Fig. 138 Upper display: distance indicator
If the sensors detect an obstacle, audible and vis-
ual signals will warn you.
Visual warnings
The visual warnings in the upper display help you
to detect the critical vehicle area and to estimate
the distance to an obstacle.
Red segments (2) show detected obstacles that
are in your vehicle's path. The red lines @) mark
the expected direction of travel based on the
steering angle. A white segment @) indicates a
detected obstacle that is outside of the vehicle's
path. The closer your vehicle comes to the obsta-
cle, the closer the segments will move to the ve-
hicle. The collision area has been reached when
the next to last segment is displayed. Obstacles
in the collision area, including those outside of
the vehicle's path, are shown in red. Do not con-
tinue driving farther.
Audio signals
The closer your vehicle gets to a detected obsta-
cle, the shorter the time between the audible sig-
nals. A continuous tone sounds when an obstacle
is less than approximately 1 foot (0.30 m) away
from the front or rear of the vehicle. A continu-
ous tone sounds when an obstacle is less than

—The side area* > page 151, fig. 108 is de-
tected and evaluated when passing. There
may have been changes to the surrounding
area after switching the ignition off and on
again, after opening the doors, or if the ve-
hicle is left stationary for a period of time.
In this case, the area will appear black until
the area has been detected and evaluated.
— If the distance to an obstacle remains con-
stant, the volume of the distance warning
gradually lowers after a few seconds until it
is muted (this does not apply to the continu-
ous tone). If the obstacle comes closer than
it was before the sound was muted, the
tone will sound again. If the obstacle be-
comes farther away than it was before the
sound was muted, no tone will sound. Pay
attention to the vehicle's surroundings
when you start to drive.
