Practical tips
recommends optimal driving for this func-
tion.
●
Due to the high temperatures caused by
the regener
ation of the particulate filter, it
is possible that the radiator fan will acti-
vate after stopping the engine, even it its
operating temperature has not been
reached.
●
Noise, smells and high idle speeds can
occur during regeneration.
●
Always use the correct engine oil and the
correct fuel to make sure the useful life of
the particulate filter is not affected. Also
avoid making short trips all the time.

Always be aware of the danger of injury and
scal
ding as w
ell as the risk of accident or fire
when working in the engine compartment
(e.g. when checking and refilling fluids).
Always observe the warnings listed below
and follow all general safety precautions.
The vehicle's engine compartment is a po-
tentially hazardous area
›››
.
WARNING
When work is done in the engine compart-
ment, injuries, burns, accidents and ev
en
fires can occur.
●
Switch the engine off, remove the key
from the ignition and apply the electronic
parking brake. If the vehicle has a manual
gearbox, place the lever in neutral; if it has
an automatic gearbox, place the selector
lever in position P. Wait for the engine to
cool down.
●
Never open the bonnet if you see steam
or drips of coolant being released from the
engine compartment. Wait until no steam
or coolant can be seen before opening the
bonnet.
●
Keep children away from the engine
compartment.
●
Never spill liquids used for vehicle opera-
tion on the engine compartment, as these
may catch fire (e.g. the antifreeze in cool-
ant).
●
Avoid causing short-circuits in the elec-
trical system, particularly at the points
where the jump leads are attached
›››
page 49. The battery could explode.
●
If working inside the engine compart-
ment, remember that, even when the igni-
tion is switched off, the radiator fan may
start up automatically, and therefore there
is a risk of injury.
●
Nev
er cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
●
Do not unscrew the cap on the coolant
expansion tank when the engine is hot. The
cooling system is under pressure.
●
Protect face, hands and arms by cover-
ing the cap with a large, thick rag to protect
against escaping coolant and steam.
●
Always make sure you have not left any
objects, such as cleaning cloths or tools, in
the engine compartment.
●
If you have to work underneath the vehi-
cle, you must use suitable stands addition-
ally to support the vehicle, there is a risk of
accident!. A hydraulic jack is insufficient for
securing the vehicle and there is a risk of
injury.
●
If any work has to be performed when the
engine is started or with the engine running,
there is an additional, potentially fatal,
safety risk from the rotating parts, such as
the drive belts, alternator, radiator fan, etc.,
and from the high-voltage ignition system.
You should also observe the following:
–
Never touch the electrical wiring of the
ignition system.
–
Ensure that jewellery, loose clothing
and long hair do not get trapped in ro-
tating engine parts. Danger of death.
Before starting any work remove jewel-
lery, tie back and cover hair, and wear
tight-fitting clothes.
