the vehicle may be braked
automatically to a small degree.
Illuminates during driving A fault in the system is present.
Continued driving is possible. Driving
stability, however, may deteriorate
depending on road surface
conditions.
Have the cause of the fault remedied
by a workshop.
Depending on version, a
corresponding warning message,
e.g. ESP unavailable , may also be
displayed in the Driver Information Centre 3 88.

Illuminates for a few seconds after the ignition is switched on.If control indicator $ illuminates, the
coolant temperature is too high. Depending on version, a warning
message may also be displayed in
the Driver Information Centre 3 88.

If engine coolant temperature is
too high, stop vehicle, switch off
the ignition. Danger to engine.
Check coolant level.
If the control indicator remains on, seek the assistance of your
workshop.

Preheating
! illuminates yellow.
Preheating of diesel engine is
activated. Only activates when
outside temperature is low.
Notice
In very hot outside
temperatures, ! may illuminate
briefly when the ignition is switched
on.
The engine can be started when !
extinguishes.

Flashes
A fault is detected in the engine
preheating system. Depending on
version, a corresponding warning
message, e.g. Check glow plugs ,
may also be displayed in the Driver
Information Centre 3 88.
If ! does not extinguish, consult a
workshop.

Air conditioning system
Additional to the heating and
ventilation system, the air
conditioning system has controls for:
n:cooling4:air recirculation
Heated front seats ß 3 39.
Heated rear window Ü 3 33.
Cooling n
Press n to switch on cooling.
Activation is indicated by 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) 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 the cooling system off to save
fuel.
Activated cooling may inhibit
Autostops. Stop-start system 3 113.
Air recirculation system Press 4 to activate air recirculation
mode. Activation is indicated by the
LED in the button.
Press 4 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.
In warm and very humid ambient air
conditions, the windscreen may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate V.
Maximum cooling Briefly open the windows so that hot
air can disperse quickly.
● Cooling n on.
● Air recirculation system 4 on.
● Set air distribution control to M.
● Set temperature control to coldest level.

Heating will not be fully effective until
the engine has reached normal

When the minimum temperature is
set below 16 ℃, the electronic climate
control system runs at maximum
cooling. LO appears in the display.
If the maximum temperature is set
above 32 ℃, the electronic climate
control system runs at maximum
heating. HI appears in the display.
Notice
If A/C is switched on, reducing the
set cabin temperature can cause the
engine to restart from an Autostop or inhibit an Autostop.

Air intake
The air intake 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 The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended that the climate control system be checked annually, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
Notice
Refrigerant R-134a contains
fluorinated greenhouse gases.
Driving and operating111Caution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
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 the
vehicle battery.

Starting the engine
Manual transmission: operate clutch

Manual transmission automated: operate brake, the transmission
automatically shifts to N (neutral)
Do not operate the accelerator pedal.
112Driving and operatingDiesel engine: turn the key to position1 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 2 and
release.
Before restarting or to switch off the
engine, turn the key back to position
0.
Autostop During an Autostop, the engine is
restarted automatically by depressing
the clutch pedal.
Vehicles with manual transmission
automated (MTA): Shift to a forward
gear, release brake pedal or move
lever to +, – or R to enable an
automatic restart.
Stop-start system 3 113.Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -25 °С for diesel engines and -30 °C
for petrol engines. Required is an engine oil with the correct viscosity,
the correct fuel, performed services
and a sufficiently charged vehicle
battery.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
Vehicle shutdown
Fuel cut-off system In the event of a collision of a certain
severity, the fuel system is cut-off and
the engine is switched off
automatically, for safety reasons.Control indicator 9 illuminates if the
fuel cut-off switch is triggered and, depending on version, a
corresponding warning message may also appear in the Driver InformationCentre 3 88.
Generic warning control indicator 9
3 79.
Notice
In addition, the vehicle is
automatically unlocked and the
hazard warning flashers and interior
lights are illuminated.
Turn the ignition key to position 0 to
prevent vehicle battery discharge and
seek the assistance of a workshop
immediately. Have the vehicle
checked for fuel leaks in the engine
compartment, beneath the vehicle
and near the fuel tank.
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Turn the ignition key to position 1 3 111.
2. Fully actuate the right turn signal light 3 99.
3. Deactivate the right turn signal light.
