Climate contro lregulates the temperature

filter sundesirable substances out of the air.
Climate contro lisonly operational when the
engin eisrunning. Optimum operation is only
achieved when the side windows and the roof
are closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 167).
i Ventilate the vehicle for
abrief period
during warm weather, e.g. using the con-
venience openin gfeature (Y page 111).
This will speed up the coolin gprocess and
the desired interior temperature will be
reached more quickly. i
The integrated filter filter
sout most par-
ticles of dust and soot and completely fil-
ter sout pollen. It also reduces gaseous pol-
lutant sand odours. Aclogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason ,you should always
observ ethe interval for replacin gthe filter,
which is specified in the Service Booklet. As this depends on environmental conditions,
e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30 minutes to dry the automatic climat econtrol. 156

R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is arisk of
fire and explosion.
Alwayst ouch the vehicle body before opening
the fuel fillerf lap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up. G
WARNING
Vehicle swithadiese lengine:
If you mix dieself uel with petrol, the flash
point of this fuel mixture is lowert han that of
pure dieself uel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is arisk of fire.
Never refuel with petrol. Never add petrol to
dieself uel.
! Do not use dieseltor

petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong
fuel.O therwise ,the fuel wille nter the fuel
system. Even small amounts of the wrong
fuel can resultind amage to the fuel system
and the engine. Notify aqualified specialist
workshop and have the fuel tank and fuel
lines drained completely.

can. The fuel lines and/or the dieseli njec-
tion system could otherwis ebeblocked by
particle sfrom the fuel can.
Do not get into the vehicle again during the
refuelling process. Otherwise ,electrostatic
charge could build up again.
If you overfill the fuel tank, some fuel may
spray out when you remove the fuel pump
nozzle.

Special service requirements
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduousc onditions
or increased loads, for example:
R regular city driving with frequent intermedi-
ate stops
R if the vehicle is primarily used to travel
short distances
R for frequent operation in mountainous ter-
rain or on poor road surfaces
R if the engine is often left idling for long peri-
ods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil
filter changed more frequently. The tyres
must be checked more frequently if the vehi-
cle is operated under increased loads. Fur-
ther information can be obtained at aquali-
fied specialist workshop, e.g. aMercedes-
Benz Service Centre.
Driving abroad
An extensive Mercedes-Benz Service network is also available in other countries. You can
obtain further information from any
Mercedes-Benz Service Centre. AdBlue

i For BlueTEC vehicles only.
To function properly, BlueTEC exhaust gas
aftertreatment must be operated with the
reducing agent AdBlue ®
.A dBlue ®
is topped
up as part of the service. Under normal oper-
ating conditions, afull tank of AdBlue ®
should
last until the next service due date.
Depending on how and where the vehicle is
used, there may be an increase in the
AdBlue ®
consumption, resulting in the next
service due date being brought forward.
Certain display messages show that AdBlue ®

qualified specialist workshop only. The
vehicle may otherwise be damaged or
soiled.
Before driving your vehicle outside Europe,
have the AdBlue ®
supply checked at aquali-
fied specialist workshop. If necessary, have
AdBlue ®
topped up. Before aprolonged stay
outside of Europe, consult aqualified special-
ist workshop.
Observe the notes on AdBlue ®
