Introduction
This chapter contains information on the following subjects:
Operation
190
manually activate/deactivate system
191The START STOP system (hereinafter referred to as the system) reduces CO 2
emissions and harmful emissions, and saves fuel.
If the system determine that the engine is not needed when the vehicle stops
or is at a standstill (e.g. at the traffic lights), it turns off the engine and starts it
again when moving off.
The system function depends on many factors. Some of them are down to the
driver, the others are systemic and can neither be influenced nor identified.
Therefore the system may react differently in situations which seem identi-
cal from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even where this has previously been manually deactivated with the button ).
Note
If the engine has stopped due to the system, the ignition remains on.

Lane changes of other vehicles / stationary vehicles
Read and observe
on page 214 first.
The following (and similar) situations require special attention and possibly the
intervention of the driver (braking, accelerating etc.).
When cornering
When driving into or driving out of long corners, it could be that a vehicle is
travelling in the adjacent lane and is scanned by the radar » Fig. 258 -
. The
host vehicle is then controlled according to this vehicle.
Narrow vehicles or vehicles travelling side by side
A narrow or offset vehicle driving can only be recognized by the ACC if this is
located in the scanning range of the radar » Fig. 258 -
.
Other vehicles changing lanes
Vehicles that change onto the lane with a small distance » Fig. 259 -
may not
be detected by ACC in good time.
Stationary vehicles
The ACC does not detect stationary objects! When a vehicle detected by the
ACC turns or sheers off and there is a stationary vehicle in front of this vehi-
cle, » Fig. 259 -
the ACC does not respond to the stationary vehicle.
Vehicles with special load or special body parts
Other vehicles with a load or with body parts protruding from the sides, back
or top of the vehicle contour may not be detected by the ACC.
Overtaking and towing
Read and observe
on page 214 first.
When overtaking
When your vehicle is being controlled at a speed that is lower than the set
speed and the turn signal is operated, ACC assesses this situation as meaning
that the driver wishes to overtake. The ACC automatically accelerates the vehi-
cle, thereby reducing the proximity to a vehicle ahead.
If your vehicle changes to the overtaking lane and no vehicle is detected
ahead, ACC accelerates until the set speed is reached and then keeps it con-
stant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 257 on page 216 .
Towing a trailer
When towing, or if another accessory is connected to the trailer socket, ACC
control is set with a lower rate. The manner of driving should therefore be
adapted to this limitation.
Malfunctions
Read and observe
on page 214 first.
If, for some unknown reason, ACC is not available, the warning light appears
in the display of the instrument cluster and an appropriate message is shown.
Sensor covered / dirty
If the sensor is dirty or covered, a message indicating that there is no sensor
view appears. Clean the sensor cover or remove the obstacles » Fig. 240 on
page 199 .
ACC not available
If the ACC is currently unavailable, a message concerning the unavailability ap-
pears. Stop the vehicle, switch off the engine and then start it again. If ACC
continues to be unavailable, seek the assistance of a specialist garage.
ACC fault
With an ACC fault, an error message appears. Seek help from a specialist ga-
rage.
218Driving
The driver's hands are on the steering wheel.
The lane is more than 2.5 m in width.
If the turn signal is switched on (e.g. when turning), no steering intervention
takes place when the vehicle approaches the boundary line. The system re-
gards the situation as an intended lane change.
Warning lights in the instrument cluster The system is active, but not ready to intervene.
The system is active and ready to intervene or is currently intervening.
Adaptive lane assist
Adaptive tracking helps to keep the vehicle in the position between the boun-
dary lines selected by the driver, by means of steering intervention.
If the position within the lane is changed, the system quickly adapts and holds
the newly-selected position.
Steering wheel vibrations
In the following situations, it may occasionally be the case that due to the
steering wheel vibrations, the system indicates that a driver steering interven-
tion is required. ▶ The system is not able to keep the vehicle by a within the lane due to a
steering intervention.
▶ During an intense system-related steering intervention, the system suddenly
cannot recognize the boundary lines.WARNINGThe system function may be restricted if, for example there is danger due
to ruts on a downhill road or in a crosswind.
Activation / deactivation
Read and observe
and on page 224 first.
The activation/deactivation of the system can be carried out in one of two
ways. ▶ In the instrument cluster display » page 47, Menu item

play.
226Driving
The system can display the following (vertical) traffic signs where identified.▶ Speed limit.
▶ Overtaking prohibited.
Additional signs, such as 'when wet' or signs which only apply for a limited
time can also be displayed.
The system displays only traffic signs that are in the “viewing area” of the sen-
sor » Fig. 267 .
Data from the sensor is supplemented by information from the Infotainment
Navigation. This is the reason why traffic signs with maximum speeds can also
be shown on sections of roads which do not have any traffic signs.

up to date or whether the vehicle is currently in a location for which no naviga-
tion data are available.
Traffic signs unavailable
No speed restriction is detected, a message is displayed regarding the unavail-
ability of road signs.
Fatigue detection
The fatigue detection system (hereinafter referred to as system) recommends
the driver takes a break from driving when driver fatigue can be detected due
to the driver's steering behaviour.
From the starting of the journey, the system evaluates the steering behaviour
at speeds 65-200 km/h. If, while driving, there have been changes in the steer-
ing behaviours that are evaluated by the system as indicating possible fatigue,
a break recommendation is issued.
Conditions under which a break from driving is detected by the system ▶ The vehicle is stopped and the ignition is turned off.
▶ The vehicle is stopped, the seat belt is taken off and the driver's door is
opened.
▶ The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.

WARNING■The general information relating to the use of assistance systems must
be observed » page 199, in section Introduction .■
For the driving ability is always the driver's responsibility. Never drive if
you feel tired.
■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The system is designed primarily for use on motorways.
Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Storing the tyre pressure values and Infotainment display
229
The tyre pressure monitoring function (hereinafter referred to as the system)
monitors the tyre pressure while driving.
If the tyre inflation pressure changes, the warning light
lights up in the in-
strument cluster and an audible signal sounds » page 35.
The system can only function properly if the tyres have the prescribed inflation
pressure and these pressure values are stored in the system.
The tyre pressure values are always stored in the system if one of the fol-
lowing events occurs.
▶ Change of tyre inflation pressure.
▶ Change one or more wheels.
▶ Change in position of a wheel on the vehicle.
▶ The warning light
lights up in the instrument cluster.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 199, in section Introduction .■
Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre inflation pressure must be checked regularly » page 261.
■
The system cannot warn in case of very rapid tyre inflation pressure loss,
e.g. in case of sudden tyre damage.
■
Before storing the pressure values, the tyres must be inflated to the
specified inflation pressure » page 261. If incorrect pressure values are
saved, the system may also not issue a warning even if the tyre inflation
pressure is too low.
CAUTION
To ensure proper system function, the tire pressure values must be stored ev-
ery 10 000 km or 1x a year.
