GWARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot, e.g.
the exhaust system.
Flammable materials such as leaves, grass or
twigs may ignite if they come into contact
with:
Rhot parts of the exhaust system
Rthe exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
Rno flammable materials come into contact
with hot vehicle components
Rthe exhaust gas can escape from the
exhaust pipe unhindered
Rthe exhaust gas does not come into contact
with flammable materials.
!Turn on the auxiliary heating at least once a
month for approximately 10 minutes. The
auxiliary heating could otherwise be dam-
aged.
!Make sure that the flow of hot air is not
blocked. The auxiliary heating will otherwise
overheat and switch off.
Your vehicle may be equipped with either an
auxiliary hot-water heater or an auxiliary warm-
air heater. Adjustment and operation of the:
Rhot-water auxiliary heater is done via the on-
board computer and with the auxiliary heating
button in the control panel (
Ypage 108) or
with the remote control (Ypage 109).
Rauxiliary warm-air heater is done via the timer
above the overhead control panel
(
Ypage 114).
The auxiliary heating works independently of the
engine and supplements the climate control
system in the vehicle. The auxiliary heating
heats the air in the vehicle interior to the tem-
perature set.
If your vehicle is equipped with a hot-water aux-
iliary heater, the auxiliary heating also keeps the
coolant warm. This way, the load on the engine
is minimized and fuel is saved.
The heater booster function (
Ypage 111) of the
au xiliary heating supports the climate control system when the engine is running and the out-
side temperature is low.
You can use the auxiliary heating at an outside
temperature of up to 39 ‡ (4 †). At an outside
temperature above 39 ‡ (4 †) the auxiliary
heating system and the heater booster function
switch off automatically.
Hot-water auxiliary heating
Heating time
The heating time when operating the auxiliary
heating with the vehicle is stationary without the
engine running depends on the outside temper-
ature and the electrical consumers switched on.

You can then switch on the auxiliary heating
again.
If you do not start the engine for a while, the total
duration of heating is limited to a maximum of
120 minutes to protect the starter battery.
Switching on the auxiliary heating is then auto-
matically disabled. You can, for example, switch
on the auxiliary heating without the engine run- ning if the outside temperature is Ò5‡( Ò20 †) a
maximum of two times. If you try it again, the
indicator lamps in the ybutton
(
Ypage 108) flash alternately for approximately
2 minutes to signal switch-on interlock. The aux-
iliary heating cannot be switched on without
starting the engine.
When the condition of charge of the starter bat-
tery is sufficient again, the switch-on interlock
will be deactivated. To charge the starter bat-
tery, let the engine run. The engine run time
required to reach the necessary condition of
charge depends on the outside temperature and
on the electrical consumers switched on.

and that it is not swallowed. Do not inhale fuelvapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
HEnvironmental note
If fuels are handled improperly, they pose a
danger to persons and the environment. Do
not allow fuels to run into the sewage system,
the surface waters, the ground water or into
the ground.
!Do not use gasoline to refuel vehicles with a
diesel engine. Even small amounts of gasoline
will cause damage to the fuel system and
engine.
!Do not switch on the ignition if you acciden-
tally refuel with the wrong fuel. Otherwise, the
fuel will enter the fuel lines. Notify a qualified
specialist workshop and have the fuel tank
and fuel lines drained completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Filter the fuel before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers.
This will prevent malfunctions in the fuel sys-
tem due to contaminated fuel.
Further information on fuel and on fuel grades
can be found in the "Technical data" section
(
Ypage 277).
Refueling procedure
The fuel filler flap is beside the front left-hand
door when viewed in the direction of travel. It is
only possible to open the fuel filler flap when the front door is open.
XRemove the key from the ignition lock.
XSwitch off the auxiliary heating system
(Ypage 106).
XOpen the front left-hand door first, and then

XTurn the key immediately to position 0in the
ignition lock and remove it.
XDo not restart the engine under any circum-
stances.
XConsult a qualified specialist workshop.
If the fuel tank has been run dry, after refueling
carry out the following steps:
XBefore starting the engine: switch on the igni-
tion three or four times.
XTurn the key to position 2in the ignition lock
(Ypage 119).
The % preglow indicator lamp in the instru-
ment cluster lights up briefly.
XOnce the %preglow indicator lamp goes
out, turn the key to position 3in the ignition
lock and release it as soon as the engine is
running.
You can start the diesel engine without preglow
when the engine is warm.
Diesel Exhaust Fluid (DEF)
Important safety notes
!Only use DEF in accordance with
ISO 22241. Never mix DEF with additives or
thin it with tap water. The exhaust gas after-
treatment may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet 352.0.
Damage that results from the use of additives
or tap water leads to the loss of the New
Vehicle Limited Warranty.
!If DEF comes into contact with a painted or
aluminum surface, wash the surface off
immediately with plenty of water.
!DEF is not a diesel additive and must not be
mixed with fuel in the tank. Even small
amounts of DEF can cause engine damage.
Damage that results from the blending of DEF
will not be covered by the New Vehicle Limi-
ted Warranty.
iIf the outside temperature is below 12 ‡
( Ò 11 †) it may be difficult to top up. If the DEF
is frozen and there is an active warning indi- cator, topping up may not be possible. Park
the vehicle in a warm place, e.g. in a garage,
until the DEF has become liquid again. Top-
ping up is then possible again. Alternatively,
have the DEF tank refilled at a qualified spe-
cialist workshop.
iIf you add DEF at temperatures below 12 ‡
( Ò 11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minute s(heating phase in
the tank activated) and then st
op the vehicle
for at least 30 seconds. The level is then
shown correctly.
You will find further information on DEF in the
"Service products" section (
Ypage 277).
