Climatronic: Control elements
First read and observe the introductory information and safety warn- ings
on page 91.
The Climatronic in automatic mode ensures the best-possible setting of the tem-
perature of the outflowing air, the blower stage and air distribution.
The system also takes sunlight into account, which eliminates the need to alterthe settings manually.
Individual functions can be adjusted by turning the knob or switching or pressing the respective button. When this function is switched on, the warning light illumi-
nates in the button.

Operational problemsFirst read and observe the introductory information and safety warn-
ings
on page 91.
If the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 236 .
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 11.
If you are not able to resolve the operational problem yourself, or if the cooler output has reduced, switch off the cooling system and seek assistance from a
specialist garage.
Auxiliary heating (auxiliary heating and ventilation)
Introduction
This chapter contains information on the following subjects:
Switching on and off directly

Conditions for the functioning of auxiliary heating (Aux. heating and ventilation),
hereinafter referred to only as auxiliary heating (Aux. heating).
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon
is not lit in the display of the
instrument cluster).
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) can be used when stationary, when the engine is switched off to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
The auxiliary heating (auxiliary heating) also warms up the engine.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank.
The coolant warms up the air, which (if the blower speed is not set to zero) flows into the passenger compartment.WARNING■ The auxiliary heater (independent vehicle heater) must never be operated in
closed rooms (e.g. garages) – risk of poisoning!■
The auxiliary heating (parking heating) must not be allowed to run during re-
fuelling – risk of fire.
■
The exhaust pipe of the auxiliary heating is located underneath the vehicle.
Therefore, if you wish to operate the auxiliary heating (auxiliary heating), do
not park the vehicle in such a way that the exhaust gases can come into con-
tact with highly flammable materials (e.g. dry grass) or easily inflammable sub-
stances (e.g. spilt fuel) – risk of fire.
CAUTION
■ The running auxiliary heating (auxiliary heating) consumes fuel from the vehicle
tank and automatically controls the filling level. If only a low quantity of fuel is
present in the fuel tank, the auxiliary heater switches itself off.■
The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating is running, the vehicle battery discharges. If the auxiliary
heating and ventilation has been operated several times over a longer period, the
vehicle must be driven a few kilometres in order to recharge the vehicle battery.
Note
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating problem.
97Heating and air-conditioning
The automatic start procedure takes place again. The warning symbol goes
out.
Further information on automatic transmission Engine shut down takes place when the selector lever is in positions P, D , S and N
and in Tiptronic mode.
When the selector lever is in position P the engine remains shut down after you
release the brake pedal. Start the engine by pressing the gas pedal or by moving
the selector lever into a different mode and releasing the brake pedal.
If the selector lever is moved into position R during the STOP phase , the engine
will re-start.
No automatic engine shutdown takes place when the vehicle is moving at low
speed (e.g. during a traffic jam or when tuning) and remains stationary after pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
Operating conditions of the system
First read and observe the introductory information and safety warn-ings
on page 149.
The START-STOP system is very complex. Some of the procedures are hard to check without servicing.
No engine shut down is carried out
Before each STOP phase, the system checks whether certain conditions have
been met. No engine shut down takes place in the following situations.
› The engine has not reached the minimum temperature for START STOP mode.
› The temperature inside the vehicle has not reached the desired temperature
set in the air-conditioning system/heating.
› The external temperature is very low/high.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The parking aid/Park Assist is switched on.
› The charge state of the vehicle battery is too low.
› The stationary vehicle is on a steep slope or a steep downhill section.
› The idling speed is too high.
› The steering angle is too large (manoeuvring).
› The selector lever position
R is selected (e.g. when parking).
The warning symbol appears in the instrument cluster display.
The automatic start procedure takes place again
During the STOP phase, the engine fires up without any active driver intervention, e.g. in the following situations.
› The vehicle begins to roll, e.g. on a slope.
› The difference between the temperature setting of the air-conditioning sys-
tem/heating and the temperature of the interior is too large.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The brake pedal was pressed several times (the pressure in the braking system
is too low).
› The charge state of the vehicle battery is too low.
› The current consumption is too high.

■Use a care cream with light blocker and impregnation effect on a regular basis
and each time after cleaning. The cream nourishes the leather, allows it to
breathe and keeps it supple and also provides moisture. It also creates surface
protection.■
Some clothing materials, e.g. dark denim, do not have sufficient colour fastness.
This can cause damage or clearly visible discolouration to seat covers, even when used correctly. This applies particularly to light-coloured seat covers. This does
not relate to a fault in the seat cover, but rather to poor colour fastness of the
clothing textiles.
Note
When using the vehicle, minor visible changes may occur to the leather parts of
the covers (e.g. wrinkles or creases) as a result of the stress applied to the covers.
Artificial leather, cloths and Alcantara ®
First read and observe the introductory information and safety warn- ings
on page 192.
Artificial leather
Clean artificial leather with a damp cloth.
If this method does not completely clean the artificial leather, use a mild soap sol-ution or cleaning products specially designed for this purpose.
Fabric
Clean upholstery cover materials and cloth trims on doors, boot cover, etc. using
specific cleaning agents, e.g., dry foam.
Use a soft sponge, brush, or commercially available microfibre cloth.
Use a cloth and a cleaning agent specifically designed for this purpose to clean
the roof trim.
Remove any lumps on the cover fabric and any fabric residue using a brush.
Remove stubborn hair using a “cleaning glove”.
Alcantara ®
Dust and fine dirt particles in pores, creases and seams may chafe and damage the surface.
If you leave your vehicle parked in the open for lengthy periods, protect the Al-
cantara ®
seat covers from the direct rays of the sun to prevent fading.
Minor changes in colour caused by use are normal.
CAUTION
■ Do not use any leather cleaners on Alcantara ®
seat covers.■For Alcantara ®
seat covers do not use any solvents, floor wax, shoe cream, stain
remover, or similar agents.■
Avoid leaving the vehicle in bright sunlight for long periods of time in order to
stop the fabric from bleaching. If the vehicle is parked outside for long periods of
time, cover the fabric to protect it from direct sunlight.

Seat covers
First read and observe the introductory information and safety warn-
ings
on page 192.
Electrically heated seats
Do not clean the covers by moistening, as this can damage the seat heating sys-
tem.
Use a specific cleaning agent such as dry foam or similar to clean the covers.
Seats without seat heating
Thoroughly vacuum the seat covers with a vacuum cleaner before cleaning.
Clean the seat covers with a damp cloth or cleaning products specially designed for this purpose.
Indented points arising on the fabrics by everyday use, can be removed by brush- ing against the direction of hair with a damp brush.
Always clean all parts of the covers, so that there are no visible edges. Then allow the seat to dry completely.
CAUTION
■ Regularly remove dust from the seat covers using a vacuum cleaner.■Electrically heated seats must not be dried after cleaning by switching on the
heater. 194General Maintenance
Oil level within range CThe engine must be topped up with oil so that the oil level at least reaches the
range B
.
The engine consumes a little oil. The oil consumption may be as much as 0.5 l/
1 000 km depending on your style of driving and the conditions under which you operate your vehicle. Consumption may be slightly higher than this during thefirst 5 000 kilometres.
The oil level must be checked at regular intervals. We recommend after each time
you refuel or prior to making a long journey.
We recommend maintaining the oil level within the range
A
, but not above , if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun- tain pass.
The indicator light in the instrument cluster will indicate whether the oil level is
too low » page 17 ,
Engine oil . Check the oil level using the dipstick as soon
as possible. Add oil accordingly.
CAUTION
The oil level must not exceed the range A » Fig. 160 – there is a risk of damaging
the exhaust system.

Replenishing
206
The coolant consists of water with coolant additive. This mixture guarantees anti- freeze protection, protects the cooling/heater system against corrosion and pre-
vents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the same antifreeze written on the antifreeze expansion tank » Fig. 161 on page 205.
204General Maintenance
WARNING■The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 199.■
Do not continue your journey if for some reason it is not possible to fill
with coolant under the current circumstances. Switch off the engine and seek
assistance from a specialist garage.
CAUTION
■ The concentration of coolant additive in the coolant must never be under 40%.■Over 60% of coolant additive in the coolant reduces the antifreeze protection
and cooling effect.■
A coolant additive that does not comply with the correct specifications can sig-
nificantly reduce the corrosion protection.
■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 161 on page 205.
■
If a fault causes the engine to overheat, we recommend visiting a specialist ga-
rage, as otherwise serious engine damage may occur.

The coolant capacity is approximately 1 l greater on vehicles that are fitted with an auxiliary heater
(auxiliary heating and ventilation).
205Inspecting and replenishing
It is necessary to disconnect both cables before charging the battery with high
amperages, known as “ rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging.WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 228, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Replacing
First read and observe the introductory information and safety warn-
ings
on page 207.
The new vehicle battery must have the same capacity, voltage, current and the
same size as the original Battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.
Disconnecting and reconnecting
First read and observe the introductory information and safety warn-
ings
on page 207.
On disconnecting and reconnecting the vehicle battery, the following functions
are initially deactivated or are no longer able to operate fault-free.

Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 207.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This manifests itself by the
following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and rear
window heaters have their power limited or are shut off completely in the event
of an emergency.
CAUTION
■ Despite such intervention by the vehicle electric system management, the vehi-
cle battery may be drained. For example, when the ignition is switched on a long
time with the engine turned off or the side or parking lights are turned on during longer parking.■
Consumers that are supplied via a 12-V power socket can cause the vehicle bat-
tery to discharge when the ignition is switched off.
