running low, a warning message will
appear in the Driver Information
Centre.1. Switch off any electrical consumers which are not requiredfor a safe drive, e.g. seat heating,
heated rear window or other main consumers.
2. Charge the vehicle battery by driving continuously for a while or
by using a charging device.
The warning message will disappear
after the engine has been started
twice without a voltage drop.
If the vehicle battery cannot be
recharged, have the cause of the fault remedied by a workshop.Vehicle personalisation
The vehicle's behaviour can be
personalised by changing the settings in the Info Display.
Some of the personal settings for
different drivers can be memorised
individually for each vehicle key.
Memorised settings 3 23.

country-specific regulations some of
the functions described below may
not be available.
Some functions are only displayed or

Driving and operating157Driving hints
Control of the vehicle
Never coast with engine not
running
Many systems will not function in this
situation ( e.g. brake servo unit, power
steering). Driving in this manner is a danger to yourself and others.
All systems function during an
Autostop.
Stop-start system 3 162.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.Use only floor mats, which fit properly and are fixed by the retainers on the
driver side.
Steering If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system. Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher.
Additionally, the cleaning process of
the exhaust filter may take place more
often.

If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.Notice
If a trailer or a bike carrier is
attached, early Autostop and late
restart is deactivated.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake. Activate the manual
parking brake without pressing the release button. Apply as
firmly as possible on a downhill slope or uphill slope. Depress
brake pedal at the same time to
reduce operating force.
For vehicles with electric
parking brake, pull switch m for
a minimum of 1 second until
control indicator m illuminates
constantly and electric parking
brake is applied 3 108.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position P before
removing the ignition key or
switching off ignition on
vehicles with power button. On
an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key or switching off ignition on
vehicles with power button.
Turn the front wheels towards
the kerb.
● Close the windows and the sunroof.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with power
button. Turn the steering wheel until the steering wheel lock is
felt to engage.
232Vehicle careVehicle battery
The vehicle battery is located in the
load compartment under the rear floor cover behind the rear seats.
Rear floor cover 3 79.
There are connecting points for jump starting in the engine compartment.
Jump starting 3 269.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge. Disconnect the clamp from
the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
Battery discharge protection 3 144.
Disconnecting the battery
If the vehicle's battery is to be
disconnected (e.g. for maintenance
work), the alarm siren must be
deactivated as follows: Switch the ignition on then off, then disconnect
the vehicle's battery within
15 seconds.
Replacing the vehicle battery
Notice
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance of the stop-start system.
When the vehicle battery is being
replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap,
and the ventilation in the vicinity of the negative terminal must be opened.
Ensure that the battery is always
replaced by the same type of battery.
We recommend that you have the
vehicle battery replaced by a
workshop.
Stop-start system 3 162.
Vehicle care233Charging the vehicle battery9Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may be damaged.
Jump starting 3 269.

● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Diesel fuel system bleeding If the tank has been run dry, the diesel
fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
