If the symbol
 lights up, you can contribute towards automatic filter
cleaning by driving in the right manner. To do this, drive about 15 minutes in
4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h, with
the engine running at approximately 2000 rpm. The increase in temperature
will burn off any soot in the filter. When cleaning is successful, the symbol
switches off.
If the symbol  does not turn off, or the three lamps turn on (particulate
filter

using the air recirculation mode in the following circumstances:
•When driving through a tunnel or in traffic congestions, to prevent
exhaust gas entering the interior of the vehicle.WARNING
Do not drive for too long with the air recirculation mode enabled because,
if the compressor is disconnected, the windscreen may mist up because no
fresh air is entering the interior of the vehicle, with the subsequent risk of
accidents.ECON Mode (economy)

adjusted automatically. “ECON” stands for “Economy”. Disconnecting air
cooling (compressor) reduces fuel consumption.
Please note that the interior temperature must not be lower than the outside
temperature in ECON mode. The blower does not cool or dehumidify the air in
the interior. The windows could therefore mist up.
In diesel vehicles, the auxiliary heater is switched off in ECON mode to save
fuel.

Driving and the environment
200Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40 seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to warm up when it is running at idling
speed. Mechanical wear and pollutant emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressure is just 1 bar too low, fuel consumption can increase by as much as 5%. Due to the greater rolling resistance, under-inflation also increases
tyre wear
and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof rack
even when it is not in use.
Save electricity
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical components when you do not need them. Examples of
components that use a lot of electricity are: the fan at high speeds, the rear
window heating or the seat heaters*.
Note
•If you vehicle has Start-Stop, it is not recommended to disconnect this
function.•It is recommended to close the windows when driving at more than 60
km/h•Do not drive with your foot resting on the clutch pedal, as the pressure can
make the plate spin, more fuel will be used and it can burn the clutch plate
lining, causing a serious fault.

Checking and refilling levels
228Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24 °C, provided you use winter-grade diesel which is
safe to -15 °C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24 °C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (thinners or similar products) with diesel fuel.
BonnetReleasing the bonnet
The bonnet is released from inside the vehicle.– To release the bonnet, pull the lever under the dash panel
⇒fig. 175 in the direction indicated (arrow).The bonnet springs out of its lock.

from oil filler opening ⇒page 301, fig. 248 .
– Carefully put in the specified grade of oil ⇒page 231, adding
0.5 litres at a time.
– After two minutes, check the oil level once again ⇒page 232.
– Where necessary, add more engine oil.
– Replace the oil filler cap carefully and push the dipstick all the way in.
WARNING
•When refilling with oil, make sure no oil falls onto hot engine parts.
Failure to comply could result in fire.•Wash your skin thoroughly if it comes into contact with engine oil.
Caution
•The oil level must never be above area . This could damage the cata-
lytic converter or the engine. Contact a qualified workshop to drain the engine
oil if necessary.•No additives should be used with engine oil. Any damage caused by the
use of such additives would not be covered by the factory warranty.For the sake of the environment
•Oil must not be disposed of in the drain or on the ground.•Always observe legal requirements when disposing of empty oil
canisters.Cooling systemCoolant fluid
The purpose of the coolant fluid is to carry heat away from the
engine. The correct amount of antifreeze is decisive in
preventing the cooling system from freezing in winter.The vehicle's engine cooling system is filled for life at the factory, so no
coolant needs to be changed. The coolant fluid consists of a mixture of water
and antifreeze G12++. This is a glycol-based antifreeze with anti-corrosion
additives.
Coolant fluid additive
The amount of antifreeze required depends on the temperatures to be
expected in the winter season. If the antifreeze concentration is too low the
coolant can freeze, resulting in failure of the cooling system and heater.
