Conditions for the system function
The following conditions are required for the correct system function.
The driver's door is closed.
The driver has fastened the seat belt.
The driving speed exceeded 4 km/h after the last stop. No trailer or other accessory is connected to the trailer socket.
System status
The system status is shown on the display » Fig. 116 when stopped.
The engine is automatically switched off; when driving off again, the en-
gine is started automatically.
The motor is not automatically switched off.
The engine does not shut down when the vehicle stops, if e.g. the following
applies.
▶ The engine temperature for the proper function of the system has not yet
been reached.
▶ The charge state of the vehicle battery is too low.
▶ The current consumption is too high.
▶ High air conditioning or heating output (high fan speed, big difference be-
tween the desired and actual interior temperature).
If the engine has shut down automatically but the system detects that the en- gine is required to run (e.g. if the brake pedal is pressed repeatedly) then the
system automatically starts up the engine.
More information about the current system status can be displayed on the In-
fotainment screen » Owner's Manual Infotainment .
If there is a system fault , the following message will appear in the display of
the instrument cluster. Seek help from a specialist garage.
Note
■ If the driver's seat belt is removed for more than 30 seconds or the driver's
door is opened after the engine has switched off automatically, the engine will
have to be restarted manually.■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shutdown
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

Parking
94
The wear and tear on the brake pads is dependent on the operating condi-
tions and driving style. In difficult conditions (e.g. urban, sporty driving), the
condition of the brakes should be checked between service intervals by a spe-
cialist garage.
Brake response can be slower if the brakes are covered in moisture or, in win-
ter, have a layer of ice or salt on them . The brakes should be cleaned and
dried by applying the brakes many times over »
.
Corrosion on the brake discs and dirt on the brake pads can occur if the vehicle
has been parked for a long period and if you do not make much use of the
braking system. The brakes are cleaned by applying the brakes several times
over »
.

Running in the engine
During the first 1 500 km, the driving style is decisive for successful the run-
ning in process is.
During the first 1 000 km , the engine should not be charged with more than
3/4 of the maximum permitted engine revs and without the trailer.
From about 1 000 to 1 500 km the engine can be pushed up to the maximum
permitted engine speed.
Tips on economical driving
Fuel consumption depends on the driving style, road and weather conditions,
and similar such factors.
For an economical driving style, the following instructions must be observed. ▶ Avoid unnecessary acceleration and braking.
▶ Observe the recommended gear » page 37.
▶ Avoid full throttle and high speeds.
▶ Reduce idling.
▶ Avoid short distances.
▶ Ensure the correct tyre inflation pressure is maintained » page 146.
▶ Avoid unnecessary ballast.
▶ Remove the roof rack before driving if it is not needed.
▶ Only turn on electrical consumers (e.g. seat heating) for as long as necessary.
▶ Briefly ventilate before turning on the cooling system, do not use the cooling
system with the windows open.
▶ Do not leave windows open at high speeds.

The Adaptive Cruise Control (hereinafter referred to as ACC) maintains the set
speed or the distance to the vehicle ahead without the accelerator or brake
pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 100.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
The driver must always be ready to take over the operation of the accel-
erator and brake pedal.
■
The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.
■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
Driving into “sharp” corners or in steep gradients / on steep inclines.
■
When driving through places where metal objects (such as metal build-
ings, railway tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

The ACC takes the current driving speed and performs the control, the warning
light illuminates in the instrument cluster.
If the control is started by moving the lever to the position and should
the speed be stored already, the ACC adopts this speed and executes control.
Note
If control is started at a speed of less than 30 km/h on vehicles with an auto-
matic transmission, the speed of 30 km/h is stored. The speed increases auto-
matically to 30 km/h or is regulated with respect to the speed of the vehicle
ahead.

112Driving
Overtaking and towingRead and observe
on page 110 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. 142 on page 111 .
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

Fatigue detection
The fatigue detection system (hereinafter referred to as "system") recom-
mends the driver takes a break from driving when driver fatigue can be detec-
ted 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 switched off.
▶ The vehicle is stopped, the seat belt removed and the driver's door opened.
▶ The vehicle is stopped for more than 15 minutes.
