Heating and cooling 100adequate cooling effect, you should not close these outlets
completely.Applies to vehicles: with deluxe automatic air conditionerEconomical operation of the air conditioner
Economical operation of the air conditioner will help to
save fuel.When the air conditioner is operating in the cooling mode it
reduces engine power and increases fuel consumption. To
ensure that the cooling mode is activated only when really
necessary, please note the following points:
– Switch off the cooling mode by pressing the AC button
(LED off) if you wish to save fuel.
– You should also switch off the cooling mode by pressing
the AC button (LED off) if you open the windows or the
tilting panorama roof* while driving.
– If the vehicle has heated up after standing in the sun,
open the windows and doors for a short time to cool the
vehicle.
For the sake of the environmentBy saving fuel you also reduce the amount of pollutants emitted
from your vehicle.

Applies to vehicles: with deluxe automatic air conditioner plusAutomatic recirculation
If the outside air is polluted, an air purity sensor in the
vehicle will automatically switch on the air recirculation.To prevent fumes, etc. in the outside air from entering the interior,
we recommend that the automatic air recirculation should be
switched on at all times.
If the air purity sensor in the air conditioner system detects a certain
concentration of fumes in the outside air, the control unit will either
pass the incoming air through the pollution filter or automatically
switch on the air recirculation. If there is a high concentration of
pollution in the outside air, the air conditioner automatically
switches to air recirculation and cuts off the supply of air from the
outside. As soon as the level of pollution decreases, air is fed into
the vehicle from the outside again.
If the windows mist up when the automatic air recirculation is on,
press the
 button immediately.
The automatic air recirculation can switch itself off in certain condi-
tions. If the outside temperature is less than about +10 °C, the auto-
matic air recirculation will only operate for 30 seconds. If the air
conditioner is switched to the ECON mode, or if the outside temper-
ature is less than about -1 °C, the automatic air recirculation will
only operate for 15 seconds.
Applies to vehicles: with deluxe automatic air conditioner plusSynchronisation
The air conditioner settings can be synchronised for all
passengers.When the synchronisation function is switched on, all subsequent
air conditioner settings made on the driver's side (except for the
seat heating*) are also applied to the front passenger's side.

Heating and cooling 110The synchronisation is cancelled as soon as any adjustments are
made on the front passenger's side.Applies to vehicles: with diesel engineSupplementary heater– Set the Supplementary heater to auto or off.Models with a diesel engine are equipped with a supplementary
heater to help warm up the interior more quickly. At outside temper-
atures below about +5 °C the supplementary heater is switched on
(and off) automatically when the engine is running, depending on
the coolant temperature, the temperature in the vehicle interior and
the temperature the heater is set to.Auxiliary heating and auxiliary
ventilationApplies to vehicles: with auxiliary heating - under development at the time of printingDescription
The auxiliary heating and ventilation systems heat and
cool the interior independently of the engine.The auxiliary heating
 works in conjunction with the air condi-
tioner system, but does not rely on heat from the engine. Instead of
this, the system burns fuel. The system's main function is to warm
up the interior of the vehicle and to defrost the windows in cold
weather.
The auxiliary heating system can be used both when the vehicle is
stationary and when driving (to provide extra heat while the engine
is warming up).The auxiliary ventilation
 also operates independently of the
engine. This feature can be used to cool the interior with the blower
when the vehicle is left parked in the sun.
The system will automatically activate either the auxiliary heating or
the auxiliary ventilation mode, depending on the actual tempera-
ture measured inside the car and the temperature you have set with
the air conditioner controls. It is possible to alter the temperature
setting while the auxiliary heating/ventilation is running.
Switching on and off
There are two different ways of switching on the auxiliary
heating/ventilation system.
•
Immediate start: You can switch the auxiliary heating/ventilation
on and off at any time via the sound system or MMI ⇒page 111. You
can also switch the system on and off using the remote control
⇒page 113.
•
Switching on via timer: You can programme various start times
using the timers ⇒page 111. However you must first activate the
timer before the auxiliary heating/ventilation system will switch on
automatically.
The auxiliary heating/ventilation will switch itself off at the end of
the programmed running time. The running time can be set to 15,
30, 45 or 60 minutes ⇒page 112.
WARNING
•
The auxiliary heating must not be allowed to run when the
vehicle is in a confined space because it can give off toxic fumes.
•
To avoid any possible fire risk, never have the auxiliary heating
switched on when refuelling the vehicle.
•
Because of the high temperatures which occur when the auxil-
iary heating is running, make sure when parking the car that the
exhaust outlet under the car is not obstructed in any way and that
the exhaust gases do not come into contact with flammable mate-
rials (fire risk).

cally changes to the next day and the Timer status is reset to off. You
have to activate one of the timers (e.g. T1 on) before it will switch on
the auxiliary heating/ventilation at the time you have set. This
prevents the auxiliary heating/ventilation from switching on when
you are not using your vehicle.
Note
Before activating the timer, make sure that the correct time and date
settings have been entered. If the time and/or date are not correct,
the auxiliary heating will come on late or not at all. Please refer to

Fuel and filling the tank 252Filling the tankFilling the tankThe flap that covers the tank cap is unlocked and locked
automatically by the central locking.
Unscrewing the tank cap
– Press the left side of the flap to open it ⇒fig. 247 -arrow-.
– Unscrew the tank cap anti-clockwise.
– Hook the cap onto the open flap ⇒fig. 248.Closing the tank cap
– Screw on the tank cap clockwise until it cannot be turned
further.
– Press the left side of the flap to close it (you should hear
it click into place).
When the automatic filler nozzle is operated correctly it will switch
itself off as soon as the 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 given on a sticker on the
inside of the tank flap. Further notes on fuel ⇒page 251.
The tank capacity of your vehicle is given in the Technical data
section ⇒page 321.
WARNING
Fuel is highly inflammable and can cause serious burns and other
injuries.•
For safety reasons always switch off the auxiliary heating*
before refuelling the vehicle.
•
For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The canister could become damaged in an
accident and leak.
•
Observe all relevant statutory regulations on using, storing and
transporting spare fuel canisters.
•
When filling your tank or a spare fuel canister with fuel, do not
smoke and keep away from naked flames. Risk of explosion!
•
If, in exceptional circumstances, you have to carry a spare fuel
canister, please observe the following warnings:
−Never fill fuel into the spare fuel canister with the canister
placed in 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.

Checking and topping up fluids 262
WARNING
•
The cooling system is under pressure. Do not unscrew the cap
on the expansion tank when the engine is hot: you could be
scalded by escaping steam
•
The coolant and coolant additive can be a health hazard. Store
the coolant additive in the original container in a safe place out of
reach of children – risk of poisoning.For the sake of the environment
Drained off coolant should not be used again. Drain off the used
coolant into a suitable container and dispose of it in the proper
manner (observe environmental regulations).Radiator fan
The radiator fan can start running spontaneously.The radiator fan is driven by the engine via a poly V-belt. The speed
of the fan is varied by a viscous clutch according to the temperature.
There is also an auxiliary electric fan, which cuts in automatically
whenever the temperature of the coolant and the engine compart-
ment rises above a certain level.
The auxiliary fan can continue to run for as long as 10 minutes after
stopping the engine – even after the ignition is switched off. It may
also start running suddenly ⇒ after a while if•
residual heat raises the coolant temperature, or
•
the hot engine compartment is additionally heated up by the
sun.
WARNING
When working in the engine compartment be aware that the radi-
ator fan may start running suddenly – risk of injury.
Brake fluidChecking brake fluid level
The brake fluid level can be checked at a glance.– Check the fluid level on the brake fluid reservoir
⇒fig. 258. It should always be between the “MIN” and
“MAX” marks.In right-hand drive vehicles the brake fluid reservoir is on the other
side of the engine compartment.
The fluid level may drop slightly after a period of time due to the
automatic compensation for brake pad wear. This is quite normal.
However, if the level goes down noticeably in a short time, or drops
below the “MIN” mark, there may be a leak in the brake system. If
the fluid level in the reservoir is too low, this will be indicated by the
brake warning lamp ⇒page 32. If this should happen, take the car
to a qualified workshop immediately and have the brake system
inspected.
