Power outlets
A 12 Volt power outlet is located in the
front console.
A further 12 Volt power outlet is
located in the rear console. Fold the
cover downwards.
Do not exceed the maximum power consumption of 120 watts.
With ignition off, the power outlets are
deactivated. Additionally the power
outlets are 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.

is displayed in percent in the Driver
Information Centre.
Reset Press SET/CLR on turn signal lever
for several seconds to reset. The

page must be active. Switch on
ignition, but not the engine.
The system must be reset every time
the engine oil is changed, to ensure
proper functionality. Seek the
assistance of a workshop.
Next service When the system has calculated that
engine oil life has diminished, a
warning message appears in the
Driver Information Centre. Have
engine oil and filter changed by a
workshop within one week or
500 km (whichever occurs first).

Battery voltage When the vehicle battery voltage is
running low, a warning message will
appear in the Driver Information
Centre.1. Switch off immediately any electrical consumers which are
not required for a safe ride, 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 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 23.
Depending on vehicle equipment and
country-specific regulations, some of the functions described below may
not be available.
Some functions are only displayed or
active when the engine is running.

Driving and operating137Driving hints
Control of the vehicle
Never coast with engine not
running (except during Autostop)
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,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 139.
Idle boost
If charging of the battery is required
due to battery condition, the power
output of the generator has to be
increased. This will be achieved by an idle boost which may be audible. A
message is displayed 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's 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.
Control indicator c 3 92.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Ground clearance
Due to the reduced ground clearance,
the vehicle can be damaged
depending on the vehicle loading and
appearance of the ground. Take
special care and drive slowly on steep driveways, entry and exit of parking
garages, high kerbs and uneven
surfaces. If possible, drive diagonally
with one wheel after another when running over kerbs or uneven
surfaces.
138Driving and operatingStarting 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 and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
vehicle battery.

Retained power off
The following electronic systems can
work until the driver's door is opened
or for a maximum of 10 minutes after
the ignition is switched off:
● power windows
● power outlets
Starting the engine
Manual transmission: operate clutch.
Automatic transmission: operate
brake and move the selector lever to
P or N.
Do not operate the accelerator pedal. Diesel engine: turn the key to position2 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 3 and
release: an automatic procedure
operates the starter with a short delay
as long as the engine is running, see
'Automatic Starter Control'.
Driving and operating141Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
'Climate control' chapter for more
details 3 129.
Immediately after motorway driving,
an Autostop may be inhibited.
New vehicle running-in 3 138.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several battery discharge protection
features are implemented as part of
the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.The engine start is indicated by the
needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 91.
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 vehiclebattery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
