136Driving and operatingDriving 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 3 140.
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.
Exhaust filter 3 144.
Autostop may be inhibited to allow
charging of the vehicle battery.
Ignition switch positions Turn key:

138Driving and operating9Warning
If the vehicle battery is discharged,
the vehicle must not be towed,
tow-started or jump-started as the
steering wheel lock cannot be
disengaged.
Operation on vehicles with
electronic key system in case of
failure
If either the electronic key fails or the
battery of the electronic key is weak,
a message may be displayed in the
Driver Information Centre.
Hold the electronic key with buttons
outside at the marking on the steering column cover as shown in the
illustration.
Operate the clutch pedal (manual
transmission), the brake pedal and
press Start/Stop .
This option is intended for
emergencies only. Replace the
electronic key battery as soon as
possible 3 23.
For unlocking or locking the doors,
see fault in radio remote control unit
or electronic key system 3 24.
Power saving mode
This mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
Infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.Changing into power saving
mode
When power saving mode is
activated, a message appears in the
Driver Information Centre.
An active telephone call using the
hands-free option will be maintained
for around 10 minutes longer.
Deactivating power saving mode
Power saving mode is deactivated
automatically when the engine is
restarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutes

144Driving and operatingEngine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
Automatic cleaning process
The exhaust filter system filters soot particles out of the exhaust gases.
The start of saturation of the exhaust
filter is indicated by the temporary
illumination of % or H ,
accompanied by a message in the
Driver Information Centre.
As soon as the traffic conditions
permit, regenerate the filter by driving at a vehicle speed of at least 60 km/huntil the control indicator
extinguishes.
Note
On a new vehicle, the first exhaust
filter regeneration operations may
be accompanied by a burning smell,
which is normal. Following
prolonged operation of the vehicle at very low speed or at idle, water
vapour can be emitted at the
exhaust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
Cleaning process not possible
If % or H stays on, accompanied
by an audible signal and a message,
this indicates that the exhaust filter
additive level is too low.
The reservoir must be topped-up
without delay. Seek the assistance of
a workshop.Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 194, 3 249 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.
