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.
Cabin air filter
Change filter regulary for maximum
effect.
More frequent passenger
compartment air filter replacement
may be needed, if you drive in areas
with heavy traffic, poor air quality,
areas with high dust levels or which
are sensitive to environmental
allergens.
Passenger compartment air filter
replacement may also be needed if
there is reduced air flow, windows
fogging up, or odors.
Your dealer can help to determine
when it is the right time to replace the
filter.
Air conditioning regularoperation
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 the
outside temperature is too low.
Service For optimal cooling performance, it is
recommended to annually check the
climate control system, starting 3
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
● cabin air filter check

● Manual transmission: during an Autostop, the engine can be
started by depressing the clutch
pedal 3 126.
● Automatic transmission: during an Autostop, the engine can be
started by releasing the brake
pedal 3 126.Starting the vehicle at low
temperatures
Starting 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.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position
P .
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.
