indicator Y is illuminated in the
instrument cluster 3 101.
Distance travelled
Displays the distance driven since the
last reset.
The measurement can be restarted at
any time.
106Instruments and controlsAverage speedThe value is displayed after driving a
distance of 400 metres.
The average speed since the last
reset is displayed.

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,

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 kmUnit 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 3 132;
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

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 50.
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 3 136.
Note
Air conditioning performance is
reduced when ECO mode has been
activated 3 130.
Air recirculation system 4
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.
120Climate controlCooling A/C
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.
Note
Air conditioning performance is
reduced when ECO mode has been
activated 3 130.
If no cooling or drying is required
press A/C OFF to switch the cooling
system off, thus saving fuel. LED
illuminates in the button.
To return to Automatic mode: Press
AUTO button.
Air recirculation mode u
Activate or deactivate manual air recirculation mode with u. LED
illuminates in the button when
activated.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.
To return to Automatic mode: Press
AUTO button.
Rear heating system
The rear passenger compartment
heating fan assists air flow to the rear
passenger compartment via the rear
air vents.
The rate of air flow is determined by
the fan. Air temperature is controlled
using the temperature control on the
instrument panel.
122Climate 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

9 Warning
When refuelling, switch off the
remote control unit as well as the
heater!
The remote control has a maximum
range of 1000 metres. The range may
be reduced due to environmental
conditions and as the battery
becomes weaker.

Teach remote control (Type B)
Up to four additional remote control
units may also be configured. During
additional teaching processes, the
oldest transmitter will be deleted each
time.
Remove the heater fuse for
five seconds, then refit the fuse.
Within two - six seconds press OFF
for one second. Teaching is
completed.
If the remote has not been used for a long period, press the OFF button six
times at intervals of two seconds,
then press and hold for another
two seconds, then wait two minutes.
Manual control
Depending on version, the auxiliary
heater can also be switched on for the
last duration time or the default
duration 30 minutes, or cut-off
immediately, using the button on the
lower part of the instrument panel,
beside the steering wheel.
The LED in the button confirms
operation.
Battery replacement
Replace the battery when the range
of the remote control is reduced or when the battery charge symbol
flashes.
