When the automatic light control
function is switched on and the
engine is running, low beam switches on automatically depending on
outside light conditions.
For reasons of safety, the light switch
should always remain in the AUTO
position.
To ensure automatic light control
functions properly, do not cover the
light sensor on top of the instrument
panel.

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 n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
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.
Activated cooling may inhibit
autostops. Stop-start system 3 126.

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 might mist up from outside, when cold air is

9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen, door
windows and in the front and rear foot wells.
The area underneath the front seats
must be kept clear, to allow air flow to

Air intake
The air intakes in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter Cabin air filtration A particle filter cleans the cabin air
from dust, soot, pollen and spores.

Driving economically Fuel economy mode
Fuel economy mode is a function that optimises fuel consumption. It affects,
e.g., engine power and torque,
acceleration and gear shift indication.
Manual transmissionActivation
Press s on the instrument panel;
LED in the button illuminates to
indicate activation.
Driving and operating123Deactivation
Press s again; LED in the button
extinguishes.
Stop-start system 3 126.
Automatic transmission
Activate fuel economy mode to allow
the transmission to adapt gearshift
patterns, improving the vehicle's fuel
economy.
Activation
In automatic mode, press s.
Control indicator s illuminates in
the instrument cluster 3 89.
The settings of certain electronic
systems are adapted to reduce fuel
consumption:
● The engine reacts less quickly to
the accelerator pedal.
● Automatic upshift points occur sooner and downshift points
occur later.
● The transmission locks itself to the engine at cruising speeds, to
improve efficiency and increase
power and torque.
● The fuel supply is automatically cut-off more quickly during
vehicle deceleration. Overrun
cut-off 3 126.
Do not use fuel economy mode whilst towing, e.g. a trailer.Deactivation
Press s again; control indicator
s 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 will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 126.
124Driving and operatingPedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
SteeringCaution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
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.
Electric power steering Electric power steering does not havepower steering fluid. Regular
maintenance is not required.
Note
If the steering wheel is turned until it
reaches the end of its travel, and is
held in that position for an extended
period of time, power steering assist
may be reduced. If used for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
If power steering assist is lost due to
a system malfunction, the vehicle can
be steered but may require increased
effort. Seek the assistance of a
workshop.
Control indicator 2 3 86.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 and the cleaning process of the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging of the
battery.
