Driver assistance
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.

ZA WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.


() Note
Before driving downhill a long distance ona
steep hill, decrease your speed and use the
braking effect of recuperation > page 94. This
reduces the load on the brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

Adaptive cruise assist
General information
Applies to: vehicles with adaptive cruise assist

Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
Within the limits of the system, the adaptive
speed
assist assists the driver in controlling the
speed and the set distance to the vehicle driving
ahead. If the system detects a vehicle driving
ahead, the adaptive speed assist can brake and
accelerate your vehicle within the limits of the
system. On open roads with no traffic, it func-
tions like a cruise control system. The stored
speed is maintained. When approaching a vehicle
driving ahead, the adaptive speed assist auto-
matically brakes to match that vehicle's speed
and then maintains the set distance as much as
possible. Once the system does not detect a vehi-
cle driving ahead, adaptive speed assist will ac-
celerate up to the set speed.
The additional lane guidance assists the driver
with corrective steering in order to stay in the
144
lane. You can adjust if the adaptive cruise assist
will provide support with lane guidance
= page 147, Switching lane guidance on and off.
In stop-and-go traffic and in traffic jams, the ve-
hicle may brake to a full stop and then may also
start driving again automatically under certain
conditions.
Applies to: vehicles with efficiency assist: Predic-
tive control can adjust the speed based on traffic
and road conditions > page 148, Predictive con-
trol.


Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 129.

@) Tips
The system complies with United States FCC
regulations and ISED regulations > page 288.
Applies to: vehicles with adaptive cruise assist



Fig. 99 Example: driving into a curve
In some situations, the adaptive cruise assist
function is limited and you must assume control
of the vehicle when necessary, for example by ap-
plying the brakes.
— When driving into a curve > fig. 99 and out of a
curve, the system may react to a vehicle in the
neighboring lane and apply the brakes. You can
override the system by pressing the accelerator
pedal briefly.

4KE012721BF
Driver assistance

— The system works with the various sensors and
cameras in the vehicle. Vehicles can only be de-
tected once they are within the area and range
covered by the sensors > page 130, fig. 90.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate unexpectedly.
— The system does not react to a stationary vehi-
cle in the same lane if it expects that you can
easily drive around the stationary vehicle by
turning the steering wheel.
— The system cannot react to stationary objects,
such as vehicles at the end of a traffic jam, es-
pecially when traveling at high speeds.
— The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle, or moving into your
lane.
— Objects that are difficult to detect, such as mo-
torcycles, vehicles with high ground clearance,
or vehicles with an overhanging load, may be
detected late or not detected at all.
— The system does not respond to people, ani-
mals, or objects that are crossing or approach-
ing from the opposite direction.

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.
