Auxiliary heater (additional
he at
er)
Introduction The auxiliary heater runs on fuel from the ve-
hic
l

e's tank and can be used while you are
driving and when the vehicle is stationary.
The auxiliary heater can be switched on using
the fast heating button of the air condition-
ing controls, with the remote control or by
previously programming a departure time in
the auxiliary heater menu of the infotainment
system.
In winter, with the auxiliary heater switched
on, you can defog the windscreen and leave
it free of ice and snow (if it is a thin layer) be-
fore you start driving.
If the outside temperature is very high, the
vehicle interior can be ventilated with the en-
gine off using the auxiliary heater. WARNING
Swallowing a battery with a 20 mm diameter
or an y

other button battery can cause serious
and even fatal injuries within a very short
time.
● Always keep the remote control, keyrings
with b
atteries, the spare batteries, button
batteries and all other batteries over 20 mm
out of reach of children. ●
If

you suspect that someone may have
swallowed a battery, seek immediate medical
attention. WARNING
The auxiliary heater exhaust fumes contain
c arbon mono

xide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death.
● Never switch on the auxiliary heater or
le

ave it running in enclosed spaces or areas
with no ventilation.
● Never programme the auxiliary heater so
that
it switches itself on and is running in an
enclosed space or an area with no ventila-
tion. WARNING
The components of the auxiliary heater are
e xtr

emely hot and could cause a fire.
● Always park your vehicle so that no part of
the exh
aust system can come in contact with
easily flammable materials that might be be-
low the vehicle, such as dried grass. CAUTION
Never place food, medicines or other temper-
at ur

e-sensitive objects close to the air vents.
Food, medicines and other objects sensitive
to heat or cold may be damaged or made un- suitable for use by the air coming from the
v
ent

s. Note
After switching the engine on with a 12-volt
b att

ery that is heavily discharged or newly
changed or after a jump start some system
settings (such as the time, the date, the per-
sonalised comfort settings and the program-
ming) might be altered or deleted. Check and
correct these settings once the battery is suf-
ficiently charged. Switching on and off the auxiliary

Air conditioning
The battery is located beneath a cover on the
b ac
k of the remote control.
● To open the cover, lift it slightly at the bot-
tom and s
lide it down.
● Remove the old battery.
● Insert the new battery. When doing so, take
into ac
count the polarity and use batteries of
the same type ››› .
● Replace the battery cover by inserting the
t ab

s at the top and pressing the bottom.
Range
The receiver is inside the vehicle. The remote
control, when fitted with new batteries, has a
range of several hundred metres. Obstacles
between the remote control and the vehicle,
bad weather conditions and discharged bat-
teries can considerably reduce the range of
the remote control. CAUTION
● The r a

dio frequency remote control con-
tains electronic components. Therefore, avoid
getting it wet and exposing it to knocks or di-
rect sunlight.
● The use of inappropriate batteries may
dam
age the radio frequency remote control.
For this reason, always replace the used bat-
tery with another of the same voltage, size
and specifications. For the sake of the environment
● Ple

ase dispose of your used batteries cor-
rectly and with respect for the environment.
● The remote control battery may contain
perc
hlorate. Observe the legal provisions re-
garding disposal.
● Care should be taken so as not to operate
the remot
e control unintentionally so as to
prevent the auxiliary heater being switched
on accidentally. Programming the auxiliary heater
Before pr
ogramming it, check that the vehi-
c
le's date and time are set correctly ››› .
The aux i
liary heater is programmed in the
Auxiliary heater menu of the infotain-
ment system.
Open the Auxiliary heater menu.
● Press the button  in the C
limatronic
control panel.
● Press the  fu
nction button.

be switched on a certain day of the week, this can
also be selected.
Duration: The duration determines the operating
time of the auxiliary heater when switched on us-
ing the fast heating button
 on the air condi-
tioning controls. The duration is also used to cal-
culate the departure time for the manual air con-
ditioner. It can be set between 10 and 60 mi-
nutes at 10-minute intervals. 
This returns to the main menu.
The programmed departure time determines
the ap
pr

oximate time it should take to reach
the temperature set in the vehicle. The start
of the heating operation is determined auto-
matically depending on the outside tempera-
ture.
Checking the programming
When a departure time is activated and the
ignition is switched off the control lamp of
the fast heating button lights up for approx-
imately 10 seconds. »

Operation
WARNING
Never programme the auxiliary heater so that
it sw
itches itself on and is running in an en-
closed space or an area with no ventilation.
The auxiliary heater exhaust fumes contain
carbon monoxide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death. Operating instructions
The auxiliary heater exhaust system located
belo
w the

vehicle must be kept clear of snow,
mud and other objects. The exhaust fumes
must be able to exit freely. The emissions
generated by the auxiliary heater are re-
moved via an exhaust pipe fitted underneath
the vehicle.
On heating the vehicle interior, depending on
the outside temperature, the warm air is first
directed at the windscreen and then to the
rest of the vehicle interior through the air
vents. Directing the diffusers – towards the
windows for example – can affect air distribu-
tion.
When will the auxiliary heater not be activa-
ted?
● The auxiliary heater requires about as
muc h po

wer as the dipped beam headlights.
If the 12-volt battery charge is too low, the auxiliary heater switches off automatically
and c
annot

be switched on. This avoids prob-
lems when starting the engine.
● The heating must be activated every time
you w
ant to set off. Similarly, the departure
time must reactivate each time.
● The control lamp  (fuel
level indicator)
lights up. Note
● Noi se

s will be heard while the auxiliary
heater is running.
● When the air humidity is high and the in-
side t
emperature low, condensation from the
heating and ventilating system may evapo-
rate when the auxiliary heater is switched on.
In this case, steam may be released from un-
derneath the vehicle. This does not mean
that there is a vehicle malfunction.
● If the vehicle is tilted, e.g. if parked on a
slope, the oper
ation of the auxiliary heater
may be restricted if the fuel tank level is low
(just above the reserve level).
● If the auxiliary heater is used a number of
times
for a long period of time, the 12-volt
battery will lose its charge. To recharge the
battery, the vehicle must be driven for a num-
ber of kilometres from time to time. As a
guideline: The journey should last approxi-
mately as long as the heater was connected.
● At temperatures below +5°C (+41°F), the
auxi
liary heater may switch itself on automat-
ically when the engine is switched on. The auxiliary heater is switched off again after a
c
er

tain time.164

Driving
●
Electric
al components with a high power
consumption are switched off temporarily
when the engine starts.
● When starting with a cold engine, noise
lev
els may briefly increase. This is quite nor-
mal, and no cause for concern.
● When the outside temperature is below
+5°C (+41°F), if
the engine is diesel, some
smoke may appear under the vehicle when the fuel-operated auxiliary heater is on. Stopping the engine

● The airbags and belt tensioners do not
work
when the ignition is switched off.
● The brake servo does not work with the en-
gine off.
Therefore, you need to press the
break pedal harder to brake the vehicle.
● Power steering does not work when the en-
gine is
not running. You need more strength
to steer when the engine is switched off.
● If the ignition is switched off, the steering
co
lumn could be locked, making it impossible
to control the vehicle. CAUTION
If the engine is made to work hard for a long
time, it m

ay overheat after being switched
off. To prevent damage to the engine before
switching it off, leave it idle for approx. 2 mi-
nutes in neutral. Note
After switching off the engine, the cooling fan
m a

y continue to operate in the engine com-
partment for a few more minutes, even with
the ignition off. The radiator fan is automati-
cally switched off. “My Beat” Function
For vehicles with a convenience key there is
the “M
y

Beat” function. This feature provides
an additional indication of the vehicle igni-
tion system.
When accessing the vehicle, e.g. by opening
the doors with the remote control, the START ENGINE STOP button flashes, calling at-
t ention t

o the relevant starter system button.
Upon switching the ignition on/off, the light
of the START ENGINE STOP button flashes. With
the en gine sw

itched off, after a few seconds,
the STOP ENGINE START button stops flashing
and g oe

s out.
With the engine running, the START ENGINE STOP button light stays on, indi-
c atin

g that the engine is running. Upon
switching the ignition off with the START ENGINE STOP button, it starts flashing
ag ain.
In

vehicles with the Start-Stop system , the
“My Beat” function also offers additional in-
formation:
● When the engine stops during the Stop
pha
se, the light of the START ENGINE STOP but-
t on s
tays on, since, even though the engine
is off, the Start-Stop system is active.
● When the engine cannot be stated again

parked. It controls the supply of power to the
v ariou
s electrical devices while the ignition is
switched off. The system takes the battery di-
agnosis data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery
from losing too much charge and to ensure
that the engine can be started reliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. Note
● Neither i s

the power management system
able to overcome the given physical limits.
Please remember that the power and useful
life of the battery are limited.
● When there is a risk that the vehicle will
not s
tart, the alternator power failure or low
battery charge level warning lamp will be
shown  ››› page 106. Flat battery
Starting ability has first priority.
Shor
t

trips, city traffic and low temperatures
all place a heavy load on the battery. In these
conditions a large amount of power is con-
sumed, but only a small amount is supplied.
The situation is also critical if electrical devi-
ces are in use when the engine is not run-
ning. In this case power is consumed when
none is being generated.
In these situations you will be aware that the
power management system is intervening to
control the distribution of electrical power.
When the vehicle is parked for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power manage-
ment will gradually shut off the electrical de-
vices one by one or reduce the amount of cur-
rent they are using. This limits the amount of
power consumed and helps to ensure relia-
ble starting even after a long period. Some
convenience functions, such as remote vehi-
cle opening, may not be available under cer-
tain circumstances. These functions will be
restored when you switch on the ignition and
start the engine. With the engine switched off
F
or e

xample, if you listen to the sound sys-
tem with the engine switched off the battery
will run down.
If the energy consumption means there is a
risk that the engine will not start, a text will
appear in vehicles with a driver information
system*.
This driver indicator tells you that you must
start the engine so that the battery can re-
charge.
When the engine is running
Although the alternator generates electrical
power, the battery can still become dis-
charged while the vehicle is being driven.
This can occur when a lot of power is being
consumed but only a small amount supplied,
especially if the battery is not fully charged
initially.
To restore the necessary energy balance, the
system will then temporarily shut off the elec-
trical devices that are using a lot of power, or
reduce the current they are consuming. Heat-
ing systems in particular use a large amount
of electrical power. If you notice, for instance,
that the seat heating* or the rear window
heater is not working, they may have been
temporarily switched off or regulated to a
lower heat output. These systems will be
available again as soon as sufficient electri-
cal power is available. »

Advice
You may also notice that the engine runs at a
s lightly
faster idling speed when necessary.
This is quite normal, and no cause for con-
cern. The increased idling speed allows the
alternator to meet the greater power require-
ment and charge the battery at the same
time. Checking and refilling levels

If the automatic filler nozzle is operated cor-
rectly, it will switch itself off as soon as the
fuel tank is “full”. Do not try to put in more
fuel after the nozzle cuts out, as this will fill
the expansion chamber in the fuel tank.
The correct fuel grade for your vehicle is giv-
en on a sticker on the inside of the fuel tank
flap. Further notes on fuel can be found at

liary heater ››› page 161 and turn off the
ignition for safety reasons.
● Do not smoke when filling the fuel tank or a

in the vehicle.
● For safety reasons we do not recommend
carr
ying a spare fuel canister in the vehicle.
In an accident the canister could be damaged
and could leak.
● If, in exceptional circumstances, you have
to c
arry a spare fuel canister, please observe
the following points:
– Never fill fuel into the spare fuel canister
if it is inside or on top of the vehicle. An
electrostatic charge could build up during
filling, causing the fuel vapour to ignite.
Danger of explosion. Always place the
canister on the ground to fill it.
– Insert the filling nozzle as far as possible
into the spare fuel canister.
– If the spare fuel canister is made of met-
al, the filling nozzle must be in contact
with the canister during filling. This
helps prevent an electrostatic charge
building up.
– Never spill fuel in the vehicle or in the
luggage compartment. Fuel vapour is ex-
plosive. Risk of fatal accident! CAUTION
● If an

y fuel is spilt onto the vehicle, it
should be removed immediately. It could oth-
erwise damage the paintwork.
● Never run the tank completely dry. An irreg-
