modifications are briefly popped-up,
superimposed over the currently
displayed menu.
The electronic climate control system
is only fully operational when the
engine is running.
Heating will not be fully effective until
the engine has reached normal
operating temperature.
Automatic mode AUTO
The system automatically controls the
fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to the desired temperature.
When the AUTO indicator light is on,
the system is in full automatic
operation.
If the air delivery mode, fan speed,
recirculation, or air conditioning
setting is adjusted, the AUTO
indicator turns off.
To improve fuel efficiency and to cool
the vehicle faster, recirculation may
be automatically selected in warmweather. The recirculation light will
not come on. Press 4 to select
recirculation; press it again to select
outside air.
To turn off the system, press power m.
Basic setting for maximum comfort: ● Press AUTO. The LED in the
button illuminates to indicate activation.
● Open all air vents to allow optimised air distribution in
Automatic mode.
● Set the preselected temperature.
Recommended temperature is
22 °C.
Temperature preselection Set temperature to the desired value.
It is indicated on the display in the
temperature control.
For reasons of comfort, change
temperature only in small increments.
If the minimum temperature Lo is set,
the climate control system runs at
maximum cooling, if cooling A/C is
active.
100Climate controlPress A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
Activated cooling might inhibit
Autostops.
Stop-start system 3 106.
Air recirculation mode 4
Press 4 to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling, the
air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper.
Maximum cooling Briefly open the windows so that hotair can disperse quickly.
● Switch on cooling A/C.
● Switch on Air recirculation system 4.
● Set temperature control to coldest level.

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 3 106.
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.
104Driving and operatingUse 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.
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 70.Caution
Vehicle equipped with electric
power steering:
If the steering wheel is turned until it reaches the end of its travel and
is held against that position for an
extended period of time, power
steering assistance may be
reduced.
If the steering assistance is used
for an extended period of time,
power assistance may be
reduced.
Power steering assistance should
return back to normal when the
system has cooled down.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.
Autostop may be inhibited to allow for
charging of the vehicle battery.
Ignition switch positions
Turn key:
106Driving and operatingBefore restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -30 °C.
Required is an engine oil with the correct viscosity, the correct fuel,
performed services and a sufficiently
charged vehicle battery.
Automatic starter control This function controls the engine
starting procedure. The driver does
not need to hold the key in position 3.
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 (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.
Overrun 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, itswitches 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.
On vehicles with manual
transmission, the engine is started automatically as soon as the clutch is depressed.
On vehicles with manual transmission
automated, the engine is started
automatically as soon as the brake
pedal is released.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
for a restart.
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.
110Driving 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.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 124, 3 177 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.
Manual transmission
To engage reverse, depress the
clutch pedal and engage the reverse
gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
Driving and operating113Manual mode
To utilise the engine braking effect, select a lower gear in good time when
driving downhill. Changing into
manual mode is only possible while the engine is running.
Rocking the vehicle Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between R and D in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
The most recently engaged gear (see transmission display) remains
engaged when switching off ignition. With N, no gear is engaged.
Therefore always apply the parking
brake when switching off ignition. If
parking brake is not applied, P flashes
in the transmission display and the
key cannot be removed from the
ignition switch. P stops flashing in the
transmission display as soon as the
parking brake is slightly applied.When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
Tyre pressure monitoring system
To start the sensor matching process of the tyre pressure monitoring
system, the selector lever must be
moved and held in position N for
five seconds. P illuminates in the
transmission display to indicate that
the sensor matching process can be
started.
Tyre pressure monitoring system
3 151.
Manual mode If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or too high an engine speed. M and the
number of the selected gear will be
flashed, then the current gear is
displayed again..If 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 with a number
alongside it, is indicated when
gearshifting is recommended for fuel saving reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
The adaptive programme tailors
gearshifting to the driving conditions, e.g. greater load or gradients.
Fault
To prevent damage to the manual
transmission automated, the clutch is engaged automatically at high clutch
temperatures.
124Driving and operatingThe lane departure warning system isactivated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on. When control indicator ) in the
instrument cluster illuminates green, the system is ready to operate.
The system is only operable at
vehicle speeds above 35 mph and if lane markings are available.
When the system recognises an
unintended lane change, control
indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.
Deactivation
The system is deactivated by
pressing ), the LED in the button
extinguishes.
At speeds below 35 mph the system
is inoperable.
Fault
The lane departure warning system may not operate properly when:
● The windscreen is not clean.
● There are adverse environmental
conditions e.g. heavy rain, snow,
direct sunlight or shadows.
The system can not operate when no lane marking is detected.Fuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
The engine is capable of running with fuel that contains up to 10% ethanol
(e.g., named E10).
Use fuel with the recommended
octane rating. The engine-specific
requirements are given in the engine data overview 3 177. A country-
specific label at the fuel filler flap can
supersede the requirement.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
