Illuminates when the engine is
runningCaution
Engine lubrication may be
interrupted. This may result in
damage to the engine and/or
locking of the drive wheels.
1. Depress clutch.
2. Select neutral gear, set selector lever to N.
3. Move out of the flow of traffic as quickly as possible without
impeding other vehicles.
4. Switch off ignition.
9 Warning
When the engine is off,
considerably more force is needed
to brake and steer. During an
Autostop the brake servo unit will still be operational.
Do not remove key until vehicle isstationary, otherwise the steeringwheel lock could engage
unexpectedly.
Check oil level before seeking
assistance of a workshop 3 140.

Driving economically ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
ActivationPress the ECO button. Control
indicator illuminates when activated
and a corresponding message
appears in the Driver Information
Centre 3 84.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal.
Deactivation
Press the ECO button again. Control
indicator extinguishes.
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
Driving and operating109
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 111.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
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.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.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
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.

Manual transmission: operate clutch.
Manual transmission automated:
operate brake; transmission
automatically shifts to N.
Do not accelerate.
Turn the key to position M for
preheating, and hold until control
indicator N extinguishes from the
Driver Information Centre.
Turn key to position D and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.
Before restarting or to switch off the
engine, turn key back to St.
During an Autostop, the engine can be started by depressing the clutch
pedal. Stop-start system 3 111.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
112Driving and operating
AutostopIf the vehicle is at low speed or
standstill, activate an Autostop as
follows:
■ depress the clutch pedal
■ shift the selector lever to neutral (manual transmission) or N
(manual transmission automated)
■ release the clutch pedal
The engine will be switched off while the ignition stays on if the required
conditions are met.
An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the heating
performance, power steering and brake performance will be
maintained. Brake assist, however, is
not available 3 123.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
■ The stop-start system is not manually deactivated
■ the bonnet is fully closed
■ the driver's door is closed or the driver's seat belt is fastened
■ the vehicle battery is sufficiently charged and in good condition
■ the engine is warmed up
■ the engine coolant temperature is not too high
■ the ambient temperature is not too low
■ the defrosting function is not activated■the climate control system does not
inhibit an Autostop
■ the brake vacuum is sufficient
■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See Climate control chapter for
further information 3 96.
Immediately after motorway driving
an Autostop may be inhibited.
Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.
New vehicle running-in 3 109.

Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the
driver
Depress the clutch pedal to restart the
engine.
If the selector lever has been shifted
out of neutral (manual transmission)
or N (manual transmission
automated) or other conditions are
not met, start using the ignition key.
The green control indicator Ï will
extinguish in the instrument cluster
when the engine is restarted.
If the selector lever is shifted out of
neutral (manual transmission) or N
(manual transmission automated) before depressing the clutch first, a
restart will not take place.Restart of the engine by the
stop-start system
The selector lever must be in neutral
(manual transmission) or N (manual
transmission automated) 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. Controlindicator Ï will flash green in the
instrument cluster during an
automatic engine restart.
■ 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 vehicle battery is discharged
■ the brake vacuum is not sufficient
■ the vehicle starts to move
■ the defrosting function is activated■ the climate control system requests
an engine start
■ the predetermined timing has been
exceeded
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.
If the Infotainment system is active,
audio sound may briefly be reduced
or interrupted during the restart.
Warning chimes 3 86.
Fault If control indicator Ï illuminates
yellow, there is a fault in the stop-start
system 3 83. A corresponding
message also appears in the Driver
Information Centre 3 84. Seek the
assistance of a workshop.
114Driving and operatingParking9Warning
■ Do not park the vehicle on an
easily ignitable surface. The
high temperature of the exhaust system could ignite the surface.
■ Always apply parking brake without pressing release button.Apply as firmly as possible on a
downhill slope or uphill slope.
Depress foot brake at the same
time to reduce operating force.
■ Switch off the engine.
■ If the vehicle is on a level surface or uphill slope, engage
first gear. On an uphill slope,
turn the front wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards
the kerb.
Lock the vehicle 3 20 and activate the
anti-theft locking system 3 28 and
anti-theft alarm system 3 28.
Air suspension
Operates automatically when the
vehicle is driven. The air suspension
system constantly adjusts the ride
height according to the vehicle load.
For further information on the air
suspension system, refer to the
operating instructions supplied.
Master switchCaution
The air suspension system must
be switched off when the vehicle is being towed, jump‐started, raised
off the ground or transported.
Do not switch off the air
suspension system when driving.
