Fuel used
Displays the amount of fuel
consumed since the last reset.
The measurement can be restarted at
any time by pressing and holding the
button on the end of the wiper lever.
Average consumption
The value is displayed after driving a
distance of 400 metres.
Average consumption is displayed, taking into consideration the distance
travelled and the fuel used since the
last reset.
The measurement can be restarted at
any time.Instantaneous consumption
The value is displayed after reaching a speed of 30 km/h.
Range The value is displayed after driving adistance of 400 metres.
The range is calculated from the
current contents of the fuel tank and
the average consumption since the
last reset.
The range will not display if control
indicator Y is illuminated in the
instrument cluster 3 96.
The measurement can be restarted at
any time.
Distance travelled
Displays the distance driven since the
last reset.
The measurement can be restarted at
any time.
Average speed
The value is displayed after driving a
distance of 400 metres.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
button on end of wiper lever.
The following trip computer
information will be reset:
● fuel used
● average consumption
● range
● distance travelled
● average speed
The trip computer will reset
automatically when the maximum
value of any of the parameters is
exceeded.

102Instruments and controlsFuel economy rating (ecoScoring)
If equipped, a rating of 0 to 100 is shown in the 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 display. Journeys can be
saved in the system memory,
enabling you to compare
performances. Refer to Infotainment
manual for further information.
Vehicle messages 3 99.
Journey record
When the engine is switched off, a
record of the last journey is shown in
the display.
The following information is
displayed:
● average fuel consumption
● trip odometer
● fuel saved in kmInterruption of power supply
If the power supply has been
interrupted or if the vehicle battery
voltage has dropped too low, the
values stored in the trip computer will be lost.Tachograph
The tachograph is operated as
described in the operating
instructions supplied. Observe
regulations regarding use.
Control indicator & illuminates in the
instrument cluster in the event of a
fault. Seek the assistance of a
workshop.

Climate control113●Set air distribution control to V.
● Switch on heated rear window Ü.
● Open side air vents as required and direct them towards door
windows.
● For simultaneous warming of the
foot well, set air distribution
control to J.
Air conditioning system
Additional to the heating and
ventilation system, the air
conditioning system has controls for:
A/C:coolingu:air recirculationHeated rear window Ü 3 40, Heated
seats ß 3 48.
Cooling (A/C)
Operated by pressing A/C and
functional only when the engine and
fan are running.
The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is a little above the freezing point. Therefore
condensation may form and drip from
under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Note
If the climate control is set to
maximum cooling while the ambient temperature is high, an Autostop
may be inhibited until the required
temperature in the passenger
compartment has been reached.
If the climate control is set to
maximum cooling while the engine is in an Autostop, the engine may
restart automatically.
Stop-start system 3 132.Air recirculation system
Operated by pressing u.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. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.
Maximum cooling
Briefly open the windows so that hotair can disperse quickly.
● Cooling A/C on.
● Air recirculation system u on.
● Set air distribution control to M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all air vents.

116Climate controlCoolingThe air conditioning system cools and
dehumidifies (dries) 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
press A/C OFF to switch the cooling
system off, thus saving fuel.
" A/C OFF " appears in the display.
Manual air recirculation mode Press u. LED illuminates and u
appears in the display.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. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.
To return to automatic mode: press
u or AUTO .
Rear heating system
If the engine is switched off, the rear
compartment can be heated by the
additional heating, through low level
vents.
By programming values using the
control panel, the user can adjust the
time, day and temperature settings.
Heating will cease to operate if the
vehicle fuel level drops too low.
During operation, power from the
vehicle battery is used. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
Note
If the rear heating system is
activated while the engine is
running, an Autostop will be
inhibited.
To ensure efficient performance, the
low level air vents in the rear
passenger compartment must not be
obstructed.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).

Climate control119Fan speed
Adjust the air flow to select the
desired speed.
turn clockwise:increase air flowturn anti-clock‐
wise:decrease air flow
Combi
Additional air conditioning is supplied
to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in use, to prevent ice forming in the
system due to lack of air movement.
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.
Note
Depending on version, an additional
coolant heater may be switched on
automatically to speed up heating
when the ignition is on and the
outside temperature is below 5 ℃.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.
