Driving and operating139Driving 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.
Stop-start system 3 144.
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 and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
battery.
Diesel particle filter 3 148.
Ignition switch positions Turn key:

Driving and operating143Before restarting or to switch off the
engine when vehicle is stationary,
press Engine Start/Stop once more
briefly.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 144.
Automatic transmission or manual
transmission automated: during an
Autostop, the engine can be started
by releasing the brake pedal 3 144.
Emergency shut off during driving If the engine needs to be switched offduring driving in case of emergency,
press Engine Start/Stop for longer
than two seconds or press twice briefly within five seconds.9 Danger
Switching off the engine during
driving may cause loss of power
support for brake and steering
systems. Assistance systems and
airbag systems are disabled.
Lighting and brake lights will
extinguish. Therefore power down the engine and ignition while
driving only when required in case of emergency.
Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct
fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx.
five minutes. The selector lever must
be in position P.
Automatic starter control
This function controls the engine
starting procedure. The driver does
not need to hold the key in position 3
or to hold Engine Start/Stop pressed.
Once applied, the system will go on
starting automatically until the engine
is running. Because of the checking procedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
● Clutch pedal not operated (manual transmission).
● Brake pedal not operated or selector lever not in P or N
(automatic transmission).
● Brake pedal not operated (manual transmission
automated).
● Timeout occurred.
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.

144Driving and operatingOverrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam.
Activation The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Deactivation
Deactivate the stop-start system
manually by pressing Ï OFF . The
deactivation is indicated when the
LED in the button illuminates.
Autostop
Vehicles with manual transmission
Depending on the engine, two
versions of an Autostop are available. See engine data to identify the engine
identifier code for your vehicle
3 247.
Conventional AutostopAll petrol engines and diesel engines
except B16DTU have only the
conventional Autostop.
An Autostop can be activated at a
standstill or at a low speed up to
3 mph.
Activate a conventional Autostop as
follows:
● Depress the clutch pedal.
● Set the lever in neutral.
● Release the clutch pedal.
The engine will be switched off while the ignition stays on.
Early Autostop
Engine B16DTU has early Autostop
in addition to conventional Autostop.
An Autostop, both conventional and
early, can be activated at a standstill
or at a low speed up to 9 mph.
Activate an early Autostop as follows: ● Depress the brake pedal.
● Depress the clutch pedal.
The engine will be switched off while
the ignition stays on.

Driving and operating149needs between seven and
12 minutes. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process
is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by % and a warning
message in the Driver Information
Centre.
% with a warning message
illuminates when diesel particle filter
is full. Start cleaning process as soon
as possible.
% with a warning message flashes
when diesel particle filter has reached the maximum filling level. Start
cleaning process immediately to
avoid damage to the engine.Cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 revolutions per minute.
Shift down if necessary. Diesel
particle filter cleaning is then started.
If cleaning is not possible for any
reasons, a warning message appears in the Driver Information Centre. Seek
the assistance of a workshop.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
A message appears as soon as the
self-cleaning operation is complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 187, 3 247 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.

Driving and operating151Without brake pedal applied, control
indicator j illuminates.
If the selector lever is not in P when
the ignition is switched off, control
indicator j flashes.
To engage P or R, press the release
button.
The engine can only be started with
the lever in position P or N. When
position N is selected, press the brake
pedal or apply the parking brake
before starting.
Do not accelerate while engaging a
gear. Never depress the accelerator
pedal and brake pedal at the same
time.
When a gear is engaged, the vehicle
slowly begins to creep when the
brake is released.
Engine braking To utilise the engine braking effect,select a lower gear in good time when
driving downhill, see manual mode.Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between D and R in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking Apply the parking brake and engageP .
The ignition key can only be removed
when the selector lever is in position
P .
Manual modeMove selector lever out of position D
towards the left in position M.
Tap selector lever upwards + to shift
to a higher gear.
Tap the selector lever downwards - to
shift to a lower gear.
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed. This can
cause a message in the Driver
Information Centre.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
The symbol R or S with a number
beside it is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.

156Driving and operatingIf engine speed is too low, the
transmission automatically shifts to a
lower gear.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
Gear shift indication
The symbol R or S with a number
beside is indicated when gearshifting
is recommended for fuel saving
reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.Kickdown
If the accelerator pedal is presseddown completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
Fault
To prevent damage to the manual transmission automated, the clutch is
engaged automatically at high clutch
temperatures.
In the event of a fault, a warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 104.
Continued driving is restricted or not
possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop beforecontinuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 93.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.

Driving and operating1879Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
Lane keep assist may not provide
enough steering to avoid a lane
departure.
The system may not detect hands-
off driving due to external
influences (road condition and
surface, weather etc). The driver
has full responsibility to control the vehicle and is always required to
keep the hands on the steering
wheel while driving.
Using the system while towing a
trailer or on slippery roads could
cause loss of control of the vehicle
and a crash. Switch the system off.
