numerical scale. In both limit positions the Climatronic operates at maximum cool-
ing or heating capacity, respectively. The temperature is not controlled in this
case.
Lengthy and uneven distribution of the air flow out of the vents (in particular at
the leg area) and large differences in temperature, for example when getting out
of the vehicle, can result in chills in sensitive persons.
Recirculated air mode In recirculated air mode air is sucked out of the interior of the vehi-
cle and then fed back into the interior. When the automatic air dis-
tribution control is switched on, an air quality sensor measures the
concentration of pollutants in the drawn in air.
Recirculated air mode prevents polluted air outside the vehicle from getting into
the vehicle, for example when driving through a tunnel or when standing in a traf-
fic jam. If a considerable increase in concentration of pollutants is recognized by
the air quality sensor, when the automatic air distribution control is switched on,
the air distribution control will temporarily be switched off. If the concentration of
pollutants decreases to the normal level, the air distribution control is automati-
cally switched off so that fresh air can be guided into the vehicle interior.
Switching recirculated air mode on
– Press the button repeatedly until the warning light on the left side of the
button lights up.
Switch on automatic air distribution control
– Press the button repeatedly until the warning light on the right side of the
button lights up.
Switch off automatic air distribution control temporarily
– If the air quality sensor does not switch on the air distribution control auto-
matically when there is a nauseating smell, you can switch it on yourself by
pressing the button . The warning light lights up in the button on the left
side.
Switching recirculated air mode off
– Press the button AUTO or press the button
repetitively, until the warning
lights in the button go out. WARNING
You should not leave recirculated air mode on over a longer period of time, as
“stale ” air may result in fatigue in the driver and occupants, divert your atten-
tion and also cause the windows to mist up. The risk of having an accident in-
creases. Switch recirculated air mode off as soon as the windows begin mist-
ing up. Note
● If the windscreen mists up, press the button
1 ⇒
fig. 92 . After the wind-
screen has been demisted, press the button AUTO .
● The automatic air distribution control operates only if the outside temperature
is higher than approx. 2 °C.
Controlling blower There are a total of seven blower stages available.
The Climatronic system controls the blower stages automatically in line with the
interior temperature. You can also, however, adapt the blower stages manually to
suit your particular needs.
–
Press again the button on the left side (reduce blower speed) or on the
right side (increase blower speed).
If you switch off the blower, the Climatronic is switched off.
The set blower speed is displayed above the button when the respective num-
ber of warning lights come on. WARNING
● “Stale air
” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an acci-
dent increases.
● Do not switch the Climatronic system off for longer than necessary.
● Switch the Climatronic system on as soon as the windows mist up. 94
Heating and air conditioning system
●
The air inlet in front of the windscreen must be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
● So that warm air can flow into the vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by you,
leave the fan switched on and leave the air outlet vents in an open position. It is
recommended to put the air flow in the position or .
Direct switching on/off Fig. 93 Button for direct switching on/
off of the auxiliary heating (auxiliary
heating and ventilation) on the operat-
ing part of the air conditioning system
The auxiliary heating (auxiliary heating and ventilation) can be switched on or off
directly with the button on the air conditioning system, Climatronic- or heating
⇒ fig. 93 .
If the auxiliary heating and ventilation is not switched off earlier, it switches off
automatically after the expiration of the set operating period, in the menu Run-
ning time.
Using the system So that the auxiliary heating (auxiliary heating and ventilation)
functions according to your expectations, it is necessary to carry
out the basic setting before its programming.
Basic setting
– On the information display, select in the Main menu the menu point Aux. heat-
ing.
– In the menu Aux. heating select the menu point Day of the wk. and set to-
day's date. –
By selecting the menu point Back, you will reach one level higher in the menu
Aux. Heating.
– In the menu Aux.
heating select the menu point Running time and set the de-
sired operating time in steps of 5 minutes. The running time can be 10 to 60
minutes.
– By selecting the menu point Back, you will reach in the menu Aux. heating.
– In the menu Aux.
heating select the menu point Mode.
– In the menu Mode select the desired mode Heating or Ventilation .
Programming For the programming of the auxiliary heating (auxiliary heating and ventilation) in
the menu Aux. heating there are three pre-set times:
● Starting time 1
● Starting time 2
● Starting time 3
In each pre-set time, the day and the time (hour and minute) can be set for
switching on the auxiliary heating and/or ventilation.
An empty position can be found between Sunday and Monday when selecting the
day. If this empty position is selected, the activation is performed without taking
into account the day.
If you leave the pre-set menu by selecting the menu Back or do not make changes
on the display for longer than 10 seconds, the set values are stored, but the pre-
set time is not active.
Both other pre-set times can be programmed and stored in the same way.
Only one programmed pre-set time can be active.
The last programmed pre-set time remains active.
After the auxiliary heating activates at the set time, it is necessary to pre-set a
time again.
Changing the active pre-set time is carried out after selecting the menu point Ac-
tivate in the menu Aux.

WARNING
● The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the vehi-
cle or carrying out similar manoeuvres.
● You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., behind your vehi-
cle. Such an obstacle might not be within the range detected by the sensors.
● Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the park-
ing aid. Note
● The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fitted towing device).
● If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no obstacle close to your car, this indi-
cates a system fault. Have the fault rectified by a specialist workshop.
● The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
Front and rear parking aid The parking aid provides a warning of obstacles in front and behind
the vehicle. Fig. 100 Activating the parking aid/detection range of the front sensors The audible parking aid determines the distance between the front or rear bump-
er and an obstacle with the aid of ultrasound sensors. The sensors are integrated
in the front and rear bumper. The signal tones for the front parking aid sound
higher as standard than for the rear parking aid. The tones of the parking aid can
be adapted in the menu of the Information display ⇒ page 20.
Range of sensors
The distance warning begins at a distance of about 120 cm from the obstacle in
front of the vehicle (area A ⇒
fig. 100 ) and about 160 cm from the obstacle behind
the vehicle (area A ⇒ fig. 99
). The interval between the warning signals becomes
shorter as the clearance is reduced.
A continuous tone sounds from a distance of approx. 30 cm (area B ) - danger
area. From this moment on do not continue driving! If the vehicle is equipped
with a factory-fitted towing device, the indication threshold of the danger area
starts -
continuous tone - 5 cm further behind the vehicle. The vehicle can be ex-
tended through an installed detachable towing device.
On factory-fitted radio navigation systems and car stereos, the distance to the ob-
struction can also be shown graphically in the display. On vehicles with a factory-
fitted towing device, the rear sensors are deactivated when towing a trailer. The
driver is informed about this by a graphic display (vehicle towing a trailer) in the
radio or the radio navigation display. The factory-fitted radio or navigation system
can be set so that the play function volume decreases when activating the park-
ing aid, see Owner's Manual radio or radio navigation system. As a result, the sig-
nal tones from the parking aid can be better recognised.
Activating
The parking aid is activated when the reverse gear is engaged and the ignition is
switched on or by pressing the button ⇒ fig. 100 - left, the symbol lights up in
the button. The activation is confirmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated after pressing the button
⇒
fig. 100 - left, or at a
speed of more than 10 km/h - the symbol in the button is no longer illuminated. £104

operate properly.
● If the parking aid is activated and the selector lever of the automatic gearbox
is in the position P , warning signal indicates interruption (vehicle can no longer
move).
Park Assist Description and important information The park assist assists you when parking in a suitable parallel parking space be-
tween two vehicles or behind a vehicle.
The park assist automatically searches for suitable parking spaces after switching
on the ignition and when driving up to 30 km/h.
During the parking procedure the park assist only takes over the steering move-
ments, the pedals continue to be operated by the driver. Function of the system is based on:
●
Length and depth measurement of the parking spaces when driving
● Evaluation of the size of the parking space
● Definition of the correct position of the vehicle for parking
● Calculating the line on which the vehicle drives backwards into the parking
space
● Actuation of the steering force assistance, automatic spinning of the wheels
of the front axle when parking. WARNING
The park assist does not take away the responsibility from the driver when
parking.
● Pay particular attention to small children and animals as they would not be
recognised by the sensors of the parking aid.
● Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the park assist or the parking aid. Thus,
these objects or people who wear such clothing are not recognised by the
sensors of the parking aid.
● The external sound source of the park assist and the parking aid can be
disruptively influenced and under unfavourable conditions, objects or people
cannot be recognised by the sensors of the parking aid. CAUTION
● If other vehicles are parked behind or on the kerb, the park assist guides your
vehicle beyond the kerb or onto it. Make sure that the wheels or the wheel rims of
your vehicle are not damaged and if necessary intervene in time.
● You should satisfy yourself before parking that there is no small obstacle, such
as a rock, thin post, trailer drawbar etc., in front or behind your vehicle. Such an
obstacle might not be within the range detected by the sensors.
● Under certain circumstances, surfaces or structures of certain objects such as
wire mesh fences, powder snow etc..., cannot be recognised by the system.
● The evaluation of the parking space and the parking procedure depends on
the circumference of the wheels. Under certain circumstances, the system may
not function correctly if your vehicle is mounted with wheels of non-permissible
size, snow chains or a temporary spare wheel (in order to reach the nearest work-
shop). If the tyres other than those excepted by the manufacturer are mounted,
the resulting position of the vehicle in the parking space can differ slightly. The
parking assistant system automatically performs the correction of the wheel cir-
cumference when driving. £ 105

Automatic gearbox DSG
Automatic gearbox DSG
Information for driving with the automatic gearbox DSG The abbreviation DSG means Direct shift gearbox (Direct shift gear-
box).
Two independent clutches are needed for the power transmission between the
engine and the gearbox. These replace the torque converter of the conventional
automatic gearbox. Their shifting is matched in such a way that there are no jerks
when shifting the gear and the power transmission of the engine to the front
wheels is not interrupted. You can also, however, switch the gearbox over into the
Tiptronic mode . This mode makes it possible for you to also shift gears manually
⇒
page 115.
Starting-off and Driving
– Depress the brake pedal fully and keep it depressed.
– Press the Shiftlock button (button in handle of the selector lever), move the
selector lever into the desired position, e.g. D ⇒
page 113, and then release
the Shiftlock button.
– Release the brake pedal and depress the accelerator ⇒
.
Stop
– The selector lever position N does not have to be selected when stopping just
for a short time, such as at a cross roads. It is sufficient to hold the vehicle sta-
tionary using the foot brake. The engine can, however, be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P
and then release the Shiftlock button.
The engine can only be started when the selector lever is in position P or N . If the
selector lever is not in the P or N positions when locking the steering, switching
the ignition on or off or when leaving the engine on, the following message will appear in the Information display
Move selector lever to position P/N! or, in the
instrument cluster display: P/N. At temperatures below -10 °C the engine can
only be started in the selector lever position P.
It is sufficient to engage selector lever position P when parking on a flat surface.
When parking on a slope you should first apply the handbrake firmly and then
move the selector lever into position P. This is to ensure that there is no excessive
pressure acting on the lock mechanism and that it is easier to subsequently move
the selector lever out of position P. If the selector lever is not in the P positin
when the driver's door is open and the ignition is switched off, or if it is not in the
P position when the ignition is switched off and the driver's door is opened, the
following message will appear in the Information display: Move selector lever to
position P! or, in the instrument cluster display: P. The message disappears af-
ter a few seconds by switching on the ignition or by moving the selector lever into
the position P .
If the selector lever position N is selected by accident while driving it is first nec-
essary to release pressure on the accelerator pedal and wait for idling speed of
the engine to be reached before engaging a drive position in the selector lever. WARNING
● Do not depress the accelerator when changing the position of the selector
lever if the car is stationary and the engine is running - risk of accident!
● Never move the selector lever into position R or P when driving - risk of an
accident!
● If you are stopping at a hill (downhill section), never try to hold the car sta-
tionary with the gear engaged by means of the
“accelerator”, this means by
letting the clutch slip. This can lead to overheating of the clutch. If there is a
risk of overheating of the clutch due to overload, the clutch is opened auto-
matically and the vehicle rolls backward - risk of accident!
● If you must stop at a slope, depress and hold the brake pedal, so that you
can prevent the vehicle from rolling back. £112
Automatic gearbox DSG
WARNING
● Never move the selector lever into position R or P when driving - risk of an
accident!
● When the engine is running and the vehicle is stationary, it is necessary to
hold the car with the brake pedal in all the positions of the selector lever (ex-
cept P and N) since the power transmission is never completely interrupted,
also not when the engine is idling - the vehicle creeps.
● You must on no account unintentionally operate the throttle (e.g. by hand
from the engine compartment) if a drive position is engaged when the car is
stationary. The vehicle would otherwise immediately start off - also when the
handbrake is firmly applied - risk of an accident!
● You must move the selector lever into position P and firmly apply the
handbrake first before you or any other person opens the bonnet and starts
working on the engine when it is running - risk of accident! It is also essential
to observe all warnings ⇒
page 190, Working in the engine compartment.
Selector lever lock Automatic selector lever lock
With the ignition on, the selector lever is locked when it is in the positions P and
N. You must first of all depress the brake pedal in order to move the selector lever
out of this position. The warning light
⇒
page 27 lights up in the instrument
cluster as a reminder for the driver when the selector lever is in the positions P
and N.
A time delay element ensures that the selector lever is not blocked when rapidly
switching over the position N (e.g. from R to D). This does, for example, allow one
to seesaw out a stuck vehicle. The selector lever lock will click into place if the lev-
er is in the N position for more than 2 seconds without the brake pedal being
pressed.
The selector lever lock is only active if the vehicle is stationary or moving at speed
of less than 5 km/hour. The lock is switched off automatically into position N
when the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of selector lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button. Keylock - Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the selec-
tor lever is in position
P. If the ignition key is withdrawn, the selector lever is
blocked in position P .
Kickdown function The kickdown function provides you with maximum acceleration
power.
Fully depressing the accelerator pedal allows the kickdown function to be activa-
ted in the desired driving program. This function has precedence over the driving
programme and serves for maximum acceleration of the vehicle when exploiting
the maximum power potential of the engine without taking into account the cur-
rent selector lever position ( D, S or Tiptronic ). The gearbox shifts down to one or
several gears in line with the driving state and the vehicle accelerates. The gear-
box does not shift up into the highest gear until the engine has reached its maxi-
mum revolutions for this gear range. WARNING
Please note that using the kickdown function can result in the driven wheels
spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme The automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed automatically on the basis of pre-defined
driving programmes.
Adopting a moderate style of driving
will cause the gearbox to select the most
economical driving programme. Shifting up into a higher gear as soon as possible
and shifting down as late as possible will have a favourable effect on your fuel
consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and frequent changes in speed, exploiting the
top speed of the car or depressing the accelerator pedal (kickdown function), will
cause the gearbox to switch over to this style of driving and shift down earlier
with frequent changes in gears in comparison to the moderate style of driving. £114
Automatic gearbox DSG
Operating principle
The TCS switches on automatically when the engine is started and then conducts
a self-test. The system monitors the speeds of the driven wheels with the aid of
the ABS sensors. If the wheels are spinning, the force transmitted to the road sur-
face is automatically adapted by reducing the engine speed. The system operates
at all speeds.
The TCS operates in combination with the ABS ⇒ page 157,
Antilock brake system
(ABS). The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instrument cluster when there is a fault on
the TCS ⇒ page 27.
During an intervention of the system, the TCS warning light flashes in the in-
strument cluster ⇒ page 27.
Switching off
You can also switch off the TCS system by pressing the ⇒ fig. 138 button, or, in ve-
hicles with ESP, by pressing the ⇒ fig. 137 button. The TCS warning light lights up
in the instrument cluster when the TCS is switched off .
The TCS should normally always be switched on. It may be good practice in certain
exceptional cases, such as when you wish to have wheel slip, to switch off the
system.
Examples:
● when driving with snow chains,
● when driving in deep snow or on a loose surface,
● when it is necessary to rock a car free when it has become stuck.
then you should switch on the TCS again.
TCS Off-road
After switching on the Off-road mode ⇒ page 160
, TCS Off-road is activated.
TCS Off-road provides a more effective acceleration of the vehicle on an unfirm
ground, as it allows higher traction between the slipping wheels and the ground.
The system operates when starting off or at low speeds. WARNING
You should always adjust your style of driving to the conditions of the road
surface and the traffic situation. The increased safety offered must not tempt
you to take greater risks than otherwise - risk of an accident! Note
● All four wheels must be fitted with the same tyres in order to achieve prob-
lem-free operation of the TCS. Differing rolling circumferences of the tyres can
lead to an undesirable reduction in the engine output.
● Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the TCS ⇒
page 207, Ac-
cessories, changes and replacement of parts.
Active driver-steering recommendation (DSR) This function indicates to the driver in critical situations a steering recommenda-
tion in order to stabilise the vehicle. The active driver-steering recommendation is
activated, for example, on the right and left vehicle side when braking sharply on
different road surfaces. WARNING
Even with this function the vehicle cannot steer itself! The driver is further-
more responsible for the steering of the vehicle!
Brakes What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions
of the vehicle and your style of driving. Particularly if you drive a great deal in
towns and over short distances or if you adopt a sporty style of driving, it may be
necessary to have the thickness of the brake pads inspected at a specialist garage
between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain con-
ditions such as when driving through water, during heavy rain showers or after
the vehicle has been washed in an automatic vehicle wash, since the brake discs
and brake pads may be moist or even have a coating of ice on them in winter. You
should dry the brakes as soon as possible by applying and releasing the brakes
several times. £ 155
