Checking and refilling levels
●
Consider the l
egal speed limits as w
ell as
the r
ecommended gears.
●
End the r
egener
ation journey once the con-
tr
ol w
arning lamp has gone out.
If the warning lamp stays on after 30 minutes
of running in regeneration mode, have a spe-
cialised workshop repair the fault
WARNING
Always adjust your speed to suit the weath-
er conditions, roads, braking distance and
traffic if the particulat
e filter is in its regen-
eration phase. Route recommendations
should never make you disregard each
country's specific traffic regulations.
CAUTION
●
When the exhaust system detects that
the particulate filt
er is close to saturation,
the self-cleaning function of this system
recommends optimal driving for this func-
tion.
●
Due to the high temperatures caused by
the regeneration 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 fir
e
when w
orking in the engine compartment
(e
.g. when checking and r
efilling fluids).
Al
ways 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 even
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 aut
omatic 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 51. 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.
●
Never 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.
