GWARNING
During convenience opening, body parts
could be drawn in or become trapped
between the side window and the door frame.
There is arisk of injury.
Monitor the entire opening procedure when
using convenience opening. When opening,
make sure that nobody touches the side win- dow. Release the %switch immediately if
somebody becomes trapped, to interrupt the
opening procedure.
XPre-entry climate control and conveni-
ence opening with the key: press and hold
the % button on the key.
The side windows open automatically and the
blower of the climate control system is acti-
vated.
XRelease the %button.
iAt high interior temperatures, the blower is
also switched on when adoor is opened. This
means that slightly cooled air enters the vehi-
cle interior after the engine is started, to cool
the vehicle more rapidly.
Switching the residual heat function
on/off
General notes
Only vehicles with automatic climate control
have the residual heat function.
Once the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.
Switching the function on/off
XTurn the key to position 0in the ignition lock
or remove it.
XPress the Ìbutton.
If the residual heat function is activated, the
indicator lamp in the Ìbutton comes on.
The blower will run at alow speed regardless
of the airflow setting.
If you activate the residual heat function at
high temperatures, only the auxiliary ventila-
tion will be activated. The blower then runs at
medium speed.
The residual heat function switches off auto-
matically

Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents .This could result in burns or frostbite in
the immediate vicinity of the air vents.T here
is ar isk of injury.
116Adjusting the air vents
Climatec ontrol

Make sure that all vehicle occupants always
maintainasufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
The center and side air vents are adjustable.
The air vents can also be adjusted on vehicles
with rear-compartment air conditioning.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet between the windshield and
the hood free of blockages, such as ice, snow
or leaves.
Rnever cover the vents or the ventilation grilles
in the vehicle interior.

airflow and air quantity control
;Thumbwheel for horizontal adjustment of
the airflow
The air vents can only be adjusted on vehicles
with rear-compartment air conditioning.
Vehicles with rear-compartment air condition-
ing: in heating mode, the air in the rear com-
partment is automatically distributed in the foot-
wells and roof area after the coolant has
reached the required temperature. In cooling
mode, in the initial phase the air is distributed in

If the engine is switched off automatically and
you exit the vehicle, the engine is restarted

Automatic engine switch-off
General notes
The ECO start/stop function is operational
when the èECO symbol is shownint he sta-
tus bar of the display.
For this to happen, various conditions, including the following, must be met:
Rthe ECO start/stop function is switched on.
The indicator lam pintheè ECO button is
lit (
Ypag e124).
Rthe outside temperature is above 32 ‡(0†).
Rthe engine has reached its operating temper-
ature.
Rthe set temperature for the vehicle interior
has beenr eached.
Rthe conditio nofcharge of the starter battery
is sufficient.
Rthe system detects that the windshield is not
foggedupw hent he air-conditioning system
or automatic climate control is switched on.
Rthe hood is closed.
Rthe driver's seatb eltisfastened.
Rthe driver's door is closed.
Rthere is no dange rofimmediately rolling
backwards ,e.g. whe nstoppedonas teep gra-
dient.
If at railer is attache dand/or arear carrier
system is installed and connected electri-
cally, this dange risdetected on less steep
gradients.
Only if al lthe conditions for automatic engine
switch-off are fulfilled, does the displays how
the è ECO symbol. All of the vehicle's systems remai
nactive when
the engine is switched off automatically.
The engine can be switched off automatically a
maximu moffour times (initial stop, then three
subsequent stops) in succession. After that, the
displayh ides theèECO symbol. Automatic
engine switch-off is not possibl eagain until the
è ECO symbol is showna gain.
If you open the hood after an automatic engine
switch-off, automatic engine start is deactiva-
ted. Once the hood is closed, you have to start
the engine manually.
If the vehicle is stoppedi
nD or N,t he
ECO start/
stop function switches off the engine automat-
ically once the vehicle is stationary.
Automatic engine start
General notes
The engine is started automatically if:
Ryou switch off the ECO start/stop function by pressing the èECO button The indicator
lamp in the èECO button then goes out.

Rthe system detects moisture on the wind-
shield whe nthe air-conditioning system is
switched on.
Rthe battery's conditio nofcharge is too low.

The coolant is amixture of water and antifreeze
and corrosion inhibitor. It performs the following
tasks:
Rcorrosion protection
Rantifreeze protection
Rraises the boiling point
When the vehicl eisfirst delivered, it is filled with
ac oolant mixture that ensure sadequate anti-
freeze and corrosion protection. Coolant must
remai ninthe engine cooling system all year
round to ensure anti-corrosion protection and a
higher boiling point, even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys-
tem, use only approved antifreeze and corrosion
inhibitor that complies with the Mercedes-Benz Specifications for Service Products.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the requirements
in the Mercedes-Benz Specifications for Service
Products Sheet Number 325.
Check the antifreeze/corrosio ninhibitor con-
centration in the coolant every six months.
The percentag eofcorrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
Rbe at least 50%. This way, the engine cooling
system is protected against freezing downt o
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡[-45 †]) .Otherwise, hea twilln ot be
dissipated as effectively.
If ther ehasbeen coolant loss, do not refill only
with water. If the vehicl ehaslost coolant, add
equa lparts water and antifreeze/corrosion
inhibitor. The water used as part of the coolant
mixture must fulfil lcertain requirements; these
are usuall yfulfille dbyd rinking water. If the
water quality is not sufficient, yo umusttrea tthe
water.

Important safety notes
The climate control system of you rvehicle is fil-
led with the refrigerant R ‑134a.
The warning label for the refrigerant being used
can be found on the radiator cross member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise ,the climate
control system may be damaged.
Maintenance work such as adding refrigerant or
replacing components may only be carried out
by aq ualified specialist workshop. All applicable
regulations thereto and the SAE standard J639
need to be respected.
All work on the climate control system should
always be carried out at qualified specialist
workshop.
