106Instruments and controlsFuel economy rating (ecoScoring)
If equipped, a rating of 0 to 100 is shown in the Infotainment system
display screen, 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.

Journey record
When the engine is switched off, a record of the last journey may be
shown in the Infotainment system
display screen.
The following information is
displayed:
● average fuel consumption
● trip odometer
● fuel saved in kmRefer to Infotainment manual for
further information.
Interruption 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

Lighting109When the automatic light control
function is switched on and the
engine is running, the system
switches between daytime running
lights (where fitted) and headlights,
depending on the lighting conditions.
For reasons of safety, the light switch

headlights are switched on.
High beamTo change between low and high
beam, pull lever until a click is felt.
High beam assist This feature allows high beam to
function as the main driving light at
night and when vehicle speed is
faster than 45 km/h.
It switches to low beam when: ● The camera in the windscreen detects the lights of oncoming or
preceding vehicles.
● It is foggy or snowy.
● Driving in urban areas.
If there are no restrictions detected,
the system switches back to high
beam.Activation
Turn the outer light switch to AUTO
then pull the turn signal lever to activate high beam assist.
The control indicator í illuminates
continuously in the instrument cluster when the assist is activated, while the
blue control indicator 7 3 101
illuminates when high beam is on.

Air conditioning system
Additional to the heating and

Cooling (A/C)
Press A/C to switch on cooling. The
LED in the button illuminates to
indicate activation. 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 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.

Air recirculation system Press u to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press u 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. 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.
