Driving safety
The driver is fully responsible for himself and passengers, especially children. If
your driving safety is effected, you place yourself and the oncoming traffic at
risk.
The following guidelines must therefore be observed. ▶ Do not become distracted from concentrating on the traffic situation, (e.g. by
your passengers or mobile phone calls).
▶ Never drive when your driving ability is impaired, (e.g. due to medication, al-
cohol or drugs).
▶ Keep to the traffic regulations and the permissible speed limit.
▶ Always adjust the driving speed to the road, traffic and weather conditions.
▶ Take regular breaks on long journeys (at least every two hours).
The following list contains instructions for the Passenger which, if not ob-
served, may cause serious injuries or death. ▶ Do not lean against the dash panel.
▶ Do not put your feet on the dash panel.
The following list contains instructions for all Passengers which, if not ob-
served, may cause serious injuries or death. ▶ Do not sit only on the front area of the seat.
▶ Do not sit facing to the side.
▶ Do not lean out of the window.
▶ Do not put your limbs out of the window.
▶ Do not put your feet on the seat upholstery.

Anti-theft alarm system
Introduction
This chapter contains information on the following subjects:
Interior monitor and towing protection
58
The anti-theft alarm system (hereinafter referred to as alarm system) increa-
ses protection against theft and break-in attempts into the vehicle.
The anti-theft alarm system is activated automatically approximately 30 sec-
onds after the vehicle is locked. This is automatically disabled after release.
The alarm system triggers audible and visual signals if an attempt is made to
break into the vehicle (hereafter referred to as alarm).
Triggering the alarm
The alarm is triggered when the following unauthorized actions are carried out
on the locked vehicle.
▶ Opening the bonnet.
▶ Opening the boot lid.
▶ Opening the doors.
▶ Manipulation of the ignition lock.
▶ Towing the vehicle.
▶ Movement in the vehicle.
▶ Sudden and significant voltage drop of the electrical system.
▶ Uncoupling the trailer.
If the driver's door of a vehicle is unlocked and opened by the lock cylinder,
then the alarm is triggered.
Switching off the alarm
The alarm is turned off by pressing the button on the key or switching on
the ignition.
CAUTION
Before leaving the vehicle, it must be checked that all of the windows, doors
and the sliding/tilting roof are locked in order to ensure the full functionality of
the anti-theft alarm system.
Note
The alarm system has its own power source. The working life of the power
supply source is 5 years.
Interior monitor and towing protection

Windscreen wipers and washers
Introduction
This chapter contains information on the following subjects:
Windscreen wipers and washers
78
Headlight cleaning system
78ABThe windscreen wipers and the wash system only operate if the ignition is
switched on and the bonnet and boot are closed.
Winter setting of the windscreen wiper
If the windscreen wipers are in rest position, they cannot be folded out from
the windscreen. For this reason we recommend adjusting the windscreen wip-
ers in winter so that they can be folded out from the windscreen easily.
▶ Switch on the windscreen wipers.
▶ Switch off the ignition.
The windscreen wipers remain in the position in which they were when
switching off the ignition.
The service position can also be used as a winter position » page 225.WARNING■
Properly maintained windscreen wiper blades are essential for clear visi-
bility and safe driving » page 225.■
Do not use the windscreen washer system at low temperatures, without
heating the windscreen beforehand. Otherwise the window washer fluid
could freeze on the windscreen and restrict the view to the front.
CAUTION
■ In cold temperatures and during the winter, check before switching on the
ignition that the wiper blades are not frozen to the windscreen. If the wind-
screen wipers are switched on when the blades are frozen to the windscreen,
this may damage both the blades and windscreen wiper motor!■
Carefully peel frozen wiper blades off the pane.
■
Remove snow and ice from the windscreen wipers before driving.
■
If the windscreen wipers are handled carelessly, there is a risk of damage to
the windscreen.
■
Do not switch on the ignition if the front wiper arms are retracted. The wiper
arms could damage the paint on the bonnet.
■
If there is an obstacle on the windscreen, the wiper will try to push away the
obstacle. The wiper stops automatically after 5 attempts to eliminate the ob-
stacle, in order to avoid a damage to the wiper. Remove the obstacle and
switch the wiper on again.
77Lights and visibility

OperationFig. 145
Display
Vehicles with manual transmission
The engine is automatically switched off as soon as the vehicle comes to a
halt, the shift lever is moved into neutral and the clutch pedal is released.
The engine is automatically started as soon as the clutch pedal is depressed.
Vehicles with automatic transmission
The engine is automatically switched off as soon as the vehicle comes to a halt
and the brake pedal is operated.
The engine is automatically started as soon as the brake pedal is released.
Conditions for the system function
The following conditions must be met for the system to function correctly.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
System status
The system status is shown in the display when the vehicle comes to a halt
» Fig. 145 .
The engine is automatically switched off; when the vehicle moves off, the
ignition process will be automatically initiated.
The engine is not automatically switched off.
Reasons for the engine running
It may be essential for the engine to keep running when the vehicle comes to
a halt, for the following reasons. ▶ 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 capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
When the engine is shut-down automatically and the system detects that the
engine is required such as when the brake pedal is pressed repeatedly then
the system automatically starts the engine.
Infotainment display
Information about the current status of the system can be displayed in the In-
fotainment display » Owner´s Manual Infotainment , chapter CAR - vehicle set-
tings .
Note
■
If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
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 shut-down
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.
125Starting-off and Driving

Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures opera-
tion of a vehicle using diesel fuel down to an environmental temperature of
-24 °C.
Diesel fuel additives
The diesel fuel in accordance with the prescribed standards meets all the con-
ditions for a smooth running engine. We therefore recommend that no diesel
fuel additives are used. This can result in considerable damage to parts of the
engine or the exhaust system.
CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system.■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with bio fuel RME, therefore this fuel must
not be filled in the tank and used for driving the vehicle. The use of biofuel
RME can cause considerable damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents) into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system.
Refuelling with CNG (compressed natural gas)
Fig. 201
Natural gas filler tubes
Read and observe and on page 189 first.
Natural gas refuelling can be carried out if the following conditions are met.
The vehicle is unlocked.
The engine and the ignition are switched off.
The auxiliary heating and ventilation is switched off » page 118.
The gas filler tube for refuelling with natural gas is located behind the fuel fill-
er flap next to the petrol filler tube.
The filling couplings of the natural gas refuelling systems may differ in han-
dling. When refuelling with natural gas at unfamiliar refuelling systems, you
should seek help from trained fuel station staff. If unsure, have the refuelling
done by trained fuel station staff.

›
Close the bonnet.
The natural gas refuelling systems have an overfill protection relating to the
outdoor temperature. At very high outside temperatures, it may happen that
the gas tank may not be fully refuelled.
The natural gas system of your vehicle is suitable both for “slow fuelling” (fuel-
ling from small compressors) and for “quick fuelling” (fuelling from natural gas
stations with large compressors).
If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not
indicate exactly the same level as was the case immediately after refuelling
