Introduction
Maximum power rating
Electrical socketMaximum power rating
12-volt120 watts
The maximum power rating of the sockets may not be exceeded. The power rating of each device
is stated on its type plate.
If two or more devices are connected at the same time, ensure that the overall power consumption
of all connected electrical devices never exceeds 190 watts ⇒.
12-volt socket
The 12-volt socket is located in the ashtray in the front centre console ⇒ Fig. 92 and works only
when the ignition is switched on.
Using electrical appliances with the engine switched off and the ignition switched on will drain the
battery. Electrical consumers should therefore only be plugged into the sockets when the engine is
running.
To prevent damage due to voltage fluctuation, switch off any connected devices before switching
the ignition or engine on or off.
Improper use of the socket and electrical accessories can cause fires and other severe
injuries.
•Never leave children in the vehicle unattended. The socket and the devices connected to it
can be used when the ignition is switched on.
•If the electrical device gets too hot, switch off the device immediately and disconnect it
from the socket.
WARNING
•In order to prevent damage to the electrical system, never connect equipment that
generates electricity, such as solar panels or battery chargers for charging the vehicle
battery, to the 12-volt socket.
•Only use accessories that have been approved in accordance with current guidelines
concerning electromagnetic compatibility.
•In order to avoid damage due to voltage fluctuation, always switch off any electrical
consumers connected to the 12-volt socket before switching the ignition or the engine on
or off. When the start/stop system automatically switches off and restarts the engine, it is
not necessary to switch off any connected electrical consumers.
•Never connect electrical devices requiring more electrical power to a 12-volt socket. The
vehicle's electrical system can be damaged if the maximum power output is exceeded.

Vehicle key positions ⇒ Fig. 93
Ignition switched off. The vehicle key can be removed.
Ignition switched on. The steering lock can be released.
Engine is started. Release the vehicle key as soon as the engine starts. Once released,
the vehicle key moves back to position ①.
If the vehicle key is left in the ignition for a long period with the engine switched off, the
vehicle battery could discharge.
Switching the engine off while the vehicle is moving makes it more difficult to stop the vehicle.
This can lead to loss of control of the vehicle and to accidents and severe injuries.
•Braking and steering support systems, the airbag system, the belt tensioners and other
items of safety equipment in the vehicle are only active when the engine is running.
•The engine should only be switched off when the vehicle is stationary.
WARNING
The risk of serious injury can be reduced with the engine running or when starting the engine.
•Never start or run the engine in unventilated or closed spaces. The exhaust fumes contain
carbon monoxide, an odourless and colourless toxic gas. Carbon monoxide can cause
loss of consciousness and death.
•Never leave the engine running if you leave the vehicle unattended. The vehicle could
move suddenly or something unexpected may happen that may cause damage and
serious injuries.
•Never use a start booster. A start booster can explode and cause the engine to suddenly
run at high revs.
WARNING
The components of the exhaust system become very hot. This can cause fires and serious
injuries.
•Never park the vehicle where parts of the exhaust system can come into contact with
inflammable material underneath the vehicle, e.g. leaves, dry grass, spilt fuel.
•Never apply additional underseal or anti-corrosion coatings to the exhaust pipes, catalytic
converters or heat shields.
WARNING
Always take care when using the vehicle key as you could cause accidents or serious injuries.
•Always take all vehicle keys with you every time you leave the vehicle. The engine can be
started and electrical equipment such as the window controls can be operated. This can
cause serious injury.
•Never leave children or people requiring assistance alone in the vehicle. They could
become trapped in the vehicle in an emergency and may not be able to get themselves to
safety. For example, locked vehicles may be subjected to very high or very low
temperatures, according to season. This can cause serious injuries and illness or
fatalities, especially for small children.
•Never remove the vehicle key from the ignition lock when the vehicle is in motion. The
steering lock may be activated and you will no longer be able to steer the vehicle.

WARNING
Incorrect parking can cause serious injuries.
•Never remove the vehicle key from the ignition lock when the vehicle is in motion. The
steering lock may be activated and you will no longer be able to steer or control the
vehicle.
•Never park the vehicle where parts of the exhaust system can come into contact with
inflammable material underneath the vehicle, e.g. leaves, dry grass, spilt fuel.
•Always apply the handbrake fully when the vehicle is parked.
•Never leave children or people requiring assistance alone in the vehicle. They could
release the handbrake, move the selector lever or gearshift lever and thus set the vehicle
in motion. This can lead to accidents and serious injuries.
•Always take all vehicle keys with you every time you leave the vehicle. The engine can still
be started and electrical equipment such as the window controls still can be operated,
potentially causing serious injury.
•Never leave children or people requiring assistance alone in the vehicle. They could
become trapped in the vehicle in an emergency and may not be able to get themselves to
safety. For example, locked vehicles may be subjected to very high or very low
temperatures, according to season. This can cause serious injuries and illness or
fatalities, especially for small children.
WARNING
•To avoid unintentional movement when parking the vehicle, first apply the handbrake firmly
and then remove your foot from the brake pedal.
•Always take care when driving in car parks with protruding kerbstones or bollards. Objects
that protrude from the ground can damage the bumper and other components when
parking the vehicle. In order to avoid any damage, stop the vehicle before the wheels
touch the bollards or kerbs.
•Drive carefully through dips in the road, over driveways, ramps, kerbstones and other
objects. Low-lying vehicle components such as the bumper, spoiler and parts of the
running gear, engine or exhaust system could be damaged.
NOTICE

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.
