104Instruments and controlsAverage speedThe value is displayed after driving a
distance of 0.25 miles.
The average speed since the last
reset is displayed.
The measurement can be restarted at
any time.
Interruptions in the journey with the
ignition off are not included in the
calculations.
Reset trip computer information
To reset the trip computer, select one of its functions then press and hold
the button on the end of the wiper
lever.
The following trip computer
information can be reset:
● fuel used
● average consumption

● average speed
The trip computer will reset
automatically when the maximum
value of any of the parameters is
exceeded.Fuel economy rating (ecoScoring)
If equipped, a rating of 0 to 100 is
shown in the Info-Display to help
evaluate fuel efficiency, based on your driving style.
Higher ratings indicate better fuel economy.
Tips to improve fuel economy are also given in the Info-Display. Journeys
can be saved in the system memory,
enabling you to compare
performances. Refer to Infotainment
manual for further information.
Vehicle messages 3 101.
Journey record
When the engine is switched off, a
record of the last journey may be
shown in the Info-Display.
The following information is
displayed:
● average fuel consumption
● total fuel consumption
● trip odometer
● fuel saved in milesUnit of measurement
To change the unit of measurement
for the duration of a journey:
Vehicles with power button:
With ignition off, simultaneously press
and hold button on end of wiper lever
and press the power button 3 130;
the central display flashes for approx. ten seconds until the new unit is
displayed. Release button on end of
wiper lever when the display stops
flashing.
Vehicles without power button:
With ignition off, simultaneously press and hold button on end of wiper lever
and switch on the ignition; the central
display flashes for approx.
ten seconds until the new unit is
displayed. Release button on end of
wiper lever when the display stops
flashing.

Climate control115● Open side air vents as requiredand direct them towards door
windows.
● For simultaneous warming of the
foot well, set air distribution
control to J.
Heated rear window 3 43.
Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:A/C:cooling4:air recirculation
Heated seats 3 48.
Cooling (A/C)
Press A/C to switch on cooling.
Activation is indicated by illumination
of the LED in the button. Cooling is
only functional when the engine is
running and climate control fan is switched on.
Press A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is above a
specific level. 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
may inhibit an Autostop.
Stop-start system 3 134.
Notice
Air conditioning performance is
reduced when ECO mode has been
activated 3 128.

Press 4
to activate air recirculation
mode. Activation is indicated by
illumination of the LED in the button.
Press 4 again to deactivate air
recirculation mode.
Climate control117The preselected temperature is
automatically regulated. In Automatic
mode, the fan speed and air
distribution automatically regulate the
air flow.
The system can be manually adapted via the use of air distribution and air
flow controls.
Electronic climate control system is only fully operational when the engine is running.
Automatic mode AUTO Basic setting for maximum comfort: ● Switch on the fan.
● Press AUTO; fan speed, air
distribution, cooling and air
recirculation are regulated
automatically.
● Set the desired temperature.
● Open all air vents.
To switch off the electronic climate
control system, switch off the fan.
Temperature preselection Temperatures can be set to the
desired value.If the minimum temperature is set, the
climate control system runs at
maximum cooling.
If the maximum temperature is set,
the climate control system runs at maximum heating.
Demisting and defrosting the
windows
● Press Ê; LED illuminates in the
button when activated.
● Temperature, air distribution and cooling are regulated
automatically and the fan runs at
high speed.
● Switch on heated rear window Ü

To return to Automatic mode: press Ê or AUTO .
Notice
If Ê is pressed while the engine is
running, an Autostop will be inhibited until Ê is pressed again.
If Ê is pressed while the engine is in
an Autostop, the engine will restart
automatically.

AUTO button.
120Climate controlSet the fan < to regulate the amount
of cooled air to be flown into the rear
passenger compartment.
Auxiliary heater Coolant heater
The engine-independent, fuel-
powered coolant heater provides
rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.
Control units

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.
Activation
Press ECO. Control indicator ECO
illuminates in the instrument cluster when activated.
Driving and operating129Notice
The use of ECO mode may affect the
performance of the climate control
system 3 114.
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 ECO again. Control indicator
ECO extinguishes in the instrument
cluster.
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 may be a controlled
reduction in power steering assist and
vehicle speed is reduced.
Stop-start system 3 134.
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.
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.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.
130Driving and operatingStarting 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.
Stop-start system 3 134.
Diesel particle filter 3 138.
Ignition switch positions
Turn key:0:ignition off: Some functions
remain active until key is
removed or driver's door is
opened, provided the ignition was on previously1:accessory power mode: Steering

Remove key from ignition switch and
turn steering wheel until it engages.9 Danger
Never remove the key from
ignition switch during driving as
this will cause steering wheel lock.
Power button
Electronic key must be inside the
vehicle, either in the card reader or
the front passenger compartment.
