control to J.
Heated rear window 3 45.
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 3 135.
Note
Air conditioning performance is
reduced when ECO mode has been
activated 3 129.
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.
Climate control119The 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.

Climate control121Rear air conditioning fan switch
The rear air conditioning fan assists
air flow to the rear passenger
compartment via the rear air vents.
Switch on the fan while the air
conditioning system is operating to
allow cooled and dehumidified (dried) air to be distributed.
The rate of air flow is determined by
the fan.
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.

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.
130Driving and operatingNote
The use of ECO mode may affect the performance of the climate control
system 3 116.
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 3 135.
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.
