Overrun
The fuel supply is automatically shut off
during overrun, e.g. when the vehicle is
being driven downhill or when braking. To
enable the overrun cut-off to take effect,
do not accelerate during overrun and, with
manual transmission, do not depress clutch
pedal. To prevent damage to the catalytic
converter, overrun cut-off is temporarily
deactivated when the catalytic converter
temperature is high.
Vehicles with turbocharged engine
Flow-generated noises may be audible if
the accelerator is released quickly on
account of airflow in the turbocharger.
Engine speed
Drive in a low engine speed range for each
gear as much as possible.
Warming up
After a cold start, the automatic
transmission 3 or Easytronic 3 in
Automatic mode shifts into higher gears at
higher rpm. This allows the catalytic
converter to quickly reach the temperature
required for optimum pollutant reduction.

Correct gear selection
Do not race your engine whilst in neutral or
with a low gear selected. Driving too fast in
individual gears as well as stop-and-go
traffic increases engine wear and fuel
consumption.
Change down
When decreasing speed, shift down into
the next lowest gear. Do not slip the clutch
with a high-revving engine. This is
especially important when hill climbing.
Clutch operation
Always depress the clutch pedal hard to
the floor to prevent shifting difficulties and
transmission damage.
When driving do not use the pedal as a
footrest; this will cause substantial clutch
wear.
Driving and operation
Cooling fan
The cooling fan is controlled via a
thermoswitch and therefore only runs if
necessary.
The cooling fan automatically switches on
when the diesel particle filter 3 is being
cleaned (depending on engine).
Pedals
Do not place any objects in the footwell
which could slip under the pedals and
inhibit the pedal travel.
To ensure the pedal travel is uninhibited,
there must be no mats in the area of the
pedals.
Battery care
When driving slowly or when the vehicle is
stationary, e.g. in slow urban traffic, stop-
and-go traffic or traffic jams, turn off all
unnecessary electrical loads where
possible (e.g. heated rear window, heated
seats).
Depress clutch pedal when starting, in
order to relieve the strain on the starter and
the battery.
