features
and
options
This chapter describes all standard, country- specific and optional features offered with theseries. It also describes features that are notnecessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and systems, the applicable laws and regulations
must be observed.
Cruise
controlConcept
Using this system, a desired speed can be adj justed using the buttons on the steering wheel.
The system maintains the desired speed. The system accelerates and brakes automaticallyas needed.
General
information
Depending on the vehicle setting, the cruise
control characteristic can change in certain ranges. For instance, the acceleration in ECOPRO driving mode is more gentle.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sysj
tem, it cannot independently react to all traffic situations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the rej
spective situations.'

limits
The desired speed is also maintained downhill. The speed may not be maintained on uphill
grades if the engine power is insufficient.
Due to the driving style that minimizes fuel
consumption in ECO PRO driving mode, the
vehicle may drop below the set desired speed
in some situations, e.g., on uphill grades.

Concept
Using this system, a desired speed and a disj
tance to a vehicle ahead can be adjusted using the buttons on the steering wheel.
The system maintains the desired speed on clear roads. For this purpose, the vehicle acj
celerates or brakes automatically.
If a vehicle is driving ahead of you, the system
adjusts the speed of your vehicle within the
given system limits so that the set distance to
the vehicle ahead is maintained.

General
information
A radar sensor is located in the front bumper and a camera on the interior mirror to detect
vehicles driving ahead of you.
Depending on the vehicle setting, the cruise
control characteristic can change in certain
ranges. For instance, the acceleration in ECO
PRO driving mode is more gentle.
The distance can be adjusted in several steps.
For safety reasons, it depends on the respecj tive speed.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pej
riod, the system is able to detect this within the
given system limits.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sysj
tem, it cannot independently react to all traffic situations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch

System
limits
Detection
range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Deceleration
The system also does not decelerate in the folj
lowing situations:
'yFor pedestrians or similarly slow-moving
road users.'yFor red traffic lights.'yFor cross traffic.'yFor oncoming traffic.
Swerving
vehicles
A vehicle driving in front of you is not detected until it is completely within the same lane as
your vehicle.
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be able to automatically restore the selected disj
tance. This also applies to major speed differj
ences to vehicles driving ahead of you, e.g., when rapidly approaching a truck. When a vej
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneuj
vers, if needed.
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves canj not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may briefly report vehicles in the next lane due to
the bend of the curve. If the system decelerj
ates you may compensate it by briefly accelerj
ating. After releasing the accelerator pedal the system is reactivated and controls speed indej
pendently.

Driving
awayIn some situations, the vehicle cannot drive off
automatically; for example:'yOn steep inclines.'yFrom bumps in the road.
In these cases, step on the accelerator pedal.
Weather
In the event of unfavorable weather and light
conditions, e.g., if there is rain, snowfall, slush, fog or glare, this may result in poorer recognijtion of vehicles as well as short-term interrupj
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.,by braking, steering or evading.
Engine
powerThe desired speed is also maintained downhill.The speed may not be maintained on uphill
grades if the engine power is insufficient.
Due to the driving style that minimizes fuel
consumption in ECO PRO driving mode, the
vehicle may intentionally exceed or drop below
the set desired speed in some situations, for
instance on downhill or uphill grades.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred, e.g., during parkj
ing.
A Check Control message is displayed if the
system fails.
Have the system checked by a dealerss service
center or another qualified service center or rej pair shop.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:
'yDuring calibration of the camera immedijately after vehicle delivery.'yIf the camera is malfunctioning or dirty. ACheck Control message is displayed.
Steering
and
lane
control
assistant
Concept
The system assists the driver in keeping the
vehicle within the lane. For this purpose, the system executes supporting steering movej
ments, for instance when driving in a curve.
General
information
The system determines the position of the lane markings and the vehicle driving ahead
using five radar sensors and a camera.
Depending on the speed, the system orients itjself according to the lane markings or vehiclesin front.
Sensors on the steering wheel detect whether
the steering wheel is being touched.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess the traffic situation. Based on the limits of the sysjtem, it cannot independently react to all trafficsituations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the rej
spective situations.'
