To adjust the time and date settings,
tap on the H and I screen buttons.
RDS clock synchronization
The RDS signal of most VHF
transmitters automatically sets the
time. RDS time synchronisation can take a few minutes. Some
transmitters do not send a correct
time signal. In such cases, it is
recommended to switch off the
automatic time synchronisation.
To activate or deactivate RDS clock
synchronization , tap on the screen
buttons On or Off.
Power outlets
A 12 Volt power outlet is located in the
centre console.
Do not exceed the maximum power
consumption of 120 watts.
With ignition off, the power outlet is
deactivated. Additionally, the power outlet is deactivated in the event of
low vehicle battery voltage.
Electrical accessories that are
connected must comply with the
electromagnetic compatibility
requirements laid down in
DIN VDE 40 839.
Do not connect any current-delivering accessories, e.g. electrical charging
devices or batteries.
Do not damage the outlet by using
unsuitable plugs.

Instruments and controls105When the vehicle battery voltage is
running low, a warning code 174 will appear in the Driver Information
Centre.
1. Switch off immediately any electrical consumers which are
not required for a safe drive, e.g.
seat heating, heated windscreen
and 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 or warning
code will disappear after the engine has been started twice consecutively
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 22.
Depending on vehicle equipment and
country-specific regulations, some of
the functions described below might
not be available.
Some functions are only displayed or

Driving and operating133Driving 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 3 135.
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.
Driving downhill
Engage a gear when driving downhill
to ensure that sufficient brake
pressure is available.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 diesel particle filter may take
place more often.
Diesel particle filter 3 139.
Autostop may be inhibited to allow for charging of the vehicle battery.
Ignition switch positions Turn key:
Driving and operating137● The engine exhaust temperatureis not too high, e.g. after driving
with high engine load.
● The ambient temperature is above -5 °C.
● The climate control system allows an Autostop.
● The brake vacuum is sufficient.
● The self-cleaning function of the diesel particle filter is not active.
● The vehicle was driven at least at
walking speed since the last Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
'Climate control' chapter for further
information 3 125.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 133.Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features, e.g. the rear window
heating, are disabled or switched into
a power saving mode. The fan speed of the climate control system is
reduced to save power.
Restart of the engine by the driverVehicles with manual transmission
Depress the clutch pedal to restart the
engine.
When the engine is restarted, control
indicator D in the Driver Information
Centre extinguishes.
If the selector lever is shifted out of
neutral before depressing the clutch
pedal first, control indicator -
illuminates or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 92.Vehicles with manual transmission
automated
Release the brake pedal or move
selector lever out of D to restart the
engine.
When the engine is restarted, control
indicator D in the Driver Information
Centre extinguishes.
Restart of the engine by the stop- start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically by the stop-start system:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and the driver's door
is opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
Vehicle care193Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Brakes
In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below the MIN mark,
seek the assistance of a workshop.
Brake and clutch fluid 3 235.
Vehicle battery
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 vehicle battery. Avoid the use of
unnecessary electrical consumers.
