Driving with respect for the environment
Introduction
This chapter contains information on the followingsubjects:
⇒ An economic driving style
⇒ Driving in a fuel-efficient manner
Fuel economy, environmental impact and wear on the engine, brakes and tyres depend largely on
three factors:

Avoid unnecessary loads
The lighter the vehicle, the more economical and environmentally-friendly it is. An extra weight of
100 kg can increase fuel consumption by up to 0.3 l/100 km.
Remove all unnecessary objects and loads from the vehicle.
Remove any unnecessary special equipment and accessories
The more aerodynamic a vehicle, the lower its fuel consumption. Special equipment and
accessories, such as roof carriers or bicycle carriers, make the vehicle less aerodynamic.
You should therefore remove any special equipment and luggage carriers that are not in use,
especially if you are going to be driving at high speeds.
Steering
Introduction
This chapter contains information on the followingsubjects:
⇒ Warning and indicator lamps
⇒ Information on steering
Depending on its equipment level the vehicle may have power steering.
The power steering is not hydraulic. It is an electromechanical system. The advantage of this
steering system is that no hydraulic hoses, hydraulic oil, pumps, filter or other parts are required.
The electromechanical system reduces fuel consumption. A hydraulic system requires constant oil
pressure in the system, whereas an electromechanical steering system only needs an energy
supply while steering.
The power steering provided by the electromechanical steering system automatically adjusts to the
vehicle speed, steering wheel torque and steering wheel angle. The electromechanical steering
only functions when the engine is running.

Information on steering
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The steering should be locked every time you leave the vehicle to make it more difficult for the
vehicle to be stolen.
Mechanical steering column lock
The steering column is locked if the vehicle key is removed from the ignition lock when the vehicle
is stationary.
Activating the steering lockDeactivating the steering lock
Park the vehicle ⇒ Braking, stopping and
parking.Insert the vehicle key into the ignition lock.
Remove the vehicle key.Turn the steering wheel slightly to take the load
off the steering lock mechanism.
Turn the steering wheel slightly until the
steering lock clicks into place.
Hold the steering wheel in this position and turn
the ignition on.
Electromechanical steering
The power steering provided by the electromechanical steering system automatically adjusts to the
vehicle speed, steering wheel torque and steering wheel angle. The electromechanical steering
only functions when the engine is running.
You will need considerably more strength than normal to steer the vehicle if the power steering is
reduced or has failed completely.

The start/stop system is not available.
Automatic engine stop active.
The start/stop system is available, but an
automatic engine stop is not possible.
Check whether all technical requirements
have been fulfilled. If not, remedy any
shortfalls ⇒ Start/stop system.
Start/stop system cannot start the engine.
Start the engine again manually using the
vehicle key ⇒ Starting and stopping the
engine.
Fault in the alternator.⇒ Vehicle battery
FlashesPossible causeSolution
Start/stop system not available.Proceed to a qualified workshop.
Several warning and indicator lamps will light up briefly as a functional check when the ignition is
switched on. They will switch off after a few seconds.
Start/stop system
Fig. 103 In the upper part of the centre console: button for the start/stop system
First read and observe the introductoryinformation and safety warnings⇒
Introduction
When the start/stop system is active, the engine is switched off whenever the vehicle is stationary.
The engine then restarts automatically as soon as it is required.
The function is automatically activated every time the ignition is switched on. The instrument cluster
display shows information about the current status ⇒ Indicator lamps.
Always switch off the start/stop system manually when driving through water.

Keep the air intake slots in front of the windscreen free of snow, ice and leaves to ensure
heating and cooling is not impaired, and to prevent the windows from misting over.

Rear window heating
The button for the rear window heating is located in the centre console. The rear window
heating only functions when the engine is running and will switch off automatically after
approximately 10 minutes.
Stale air can quickly cause tiredness and lack of concentration in the driver, which in turn can
cause collisions, accidents and serious injuries.

Natural gas engines
Things to note: if the vehicle is parked for an extended period directly after refuelling, it may well
occur that the pointer for the natural gas engine does not indicate the fuel level shown directly after
refuelling. This does not mean that there is a leak in the system but but rather that, for technical
reasons the pressure has been decreased in the natural gas tank.
The small arrow next to the petrol pump symbol ⇒ Fig. 115 in the display instrument shows
you the side of the vehicle on which the tank flap is located.
