Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 129.
— The adaptive cruise assist is only an assist
system, and the driver is still responsible for
controlling the vehicle. The driver is espe-
cially responsible for braking, steering,
starting to drive, and controlling the speed
and the distance from other vehicles.
— Turn on the adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these

situations.


— If you press the [SET] button @) when driv-
ing at speeds below 15 mph (20 km/h), the
minimum possible speed that the system
can maintain will be set. If no vehicle is de-
tected ahead of you, the vehicle will acceler-
ate up to that speed.
@ Tips
— Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— If you switch the ignition or the adaptive
cruise assist off, the stored speed is erased
for safety reasons.
— When the adaptive cruise assist is switched
on, the ESC and the ASR are switched on au-
tomatically.
— The system cannot be switched off or it may
be interrupted if the road exceeds the maxi-
mum possible grade for safe operation.

approaching from behind and provide a warning
when you are changing lanes and turning. The
system uses the data from the radar sensors at
the rear corners of the vehicle.
The side assist is active at walking speeds and
higher. If an object that is classified as critical is
approaching, the display in the exterior mirror @)
on the corresponding side of the vehicle will light
up.
Driving situations
The system can provide warnings about the fol-
lowing risks:
@ Approaching vehicles: a vehicle may be clas-
sified as critical in some cases, even if it is
farther away. The faster a vehicle ap-
proaches, the sooner the display will turn on.
@® Vehicles traveling in the same direction: the
display will turn on if vehicles traveling in the
same direction as your vehicle are classified
as critical. The side assist warns you of all de-
tected vehicles when they are in the “blind
spot” or before they reach that point.
@® Vehicles you are passing: the display only
turns on if you slowly pass a detected vehicle
(difference in speed between the two vehicles
is less than 9 mph (15 km/h)). There is no
display if you pass a vehicle more quickly.
Information stage
At the information level, the side assist informs
you of detected objects that are classified as criti-
cal. This is even possible when your vehicle is sta-
tionary and the turn signal is turned on, so that
the system can also assist you when turning.
From speeds of approximately 6 mph (10 km/h)
and higher, the system will warn you of detected
objects that are classified as critical, even if the
turn signal is not turned on.
The display remains dim in the information stage
so that you are not distracted while looking for-
ward.
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 155,
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 129.
— 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:

— These systems are not available in trailer
towing mode. There is no guarantee the sys-
tems will switch off when using a retrofitted
trailer hitch. Do not use these functions
