Heating and air conditioning systemAir outlet ventsThe information provided is valid for all vehicles.Fig. 87 Air outlet ventsOpen the air outlet vents 3 and 4– Turn the vertical thumbwheel (air outlet vents 3) or the horizontal wheel (air outlet
vents 4) to the position
.
Close air outlet vents 3 and 4– Turn the vertical thumbwheel (air outlet vents 3) or the horizontal wheel (air outlet
vents 4) to the position 0.Change air flow of air outlet vents 3 and 4– In order to change the strength of the ai r flow, swivel the horizontal lamellas with
the aid of the moveable adjuster.
– In order to change the lateral direction of the air flow, turn the vertical lamellas with the aid of the moveable adjuster.
You can set the air supply to the individual vents with the air distribution control
 page 79, fig. 88 . Air outlet vents 3 and 4 can also be opened or closed individually. Warmed, unwarmed or cooled air will flow out of the air outlet vents according to the
setting of the regulator of the heating or the air conditioning system* and the atmos-
pheric conditions.
Recirculated air modeIn recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.Recirculated air mode prevents polluted air outside the vehicle from getting into the
vehicle, for example when driving through a tunnel or when standi
ng in a traffic jam.Switching recirculated air mode on– Press the button page 81, fig. 89 , the warning light lights up in the
button.Switching recirculated air mode off– Press again the button - the warning light in the button goes out.
The recirculated air mode is switched off automatically if the air distribution control
is in position
  page 81, fig. 89. You can also switch recirc ulated air mode on again
from this setting by repe atedly pressing button .
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
increases. Switch recirculated air mo de off as soon as the windows begin
misting up.

Technical Data
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 lo ck will click into place if the lever 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 swit ched off automatically into position N when the
car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the hand le of selector lever prevents certain selector lever posi-
tions 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 selector
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 activated 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 wi thout taking into account the current
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 gearbox does not
shift up into the highest gear until the engine has reached its maximum 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 programmeThe 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 po ssible will have a favourable effect on your fuel consump-
tion.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and freque nt 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.
Selecting the most appropriate driving programme for the particular style of driving is
a continuous process. Irrespective of this it is, however, possible to switch or shift down
into a dynamic shift programme by depressi ng the accelerator rapidly. The gearbox
shifts down into a lower gear matching the speed of the car and this allows you to
accelerate rapidly (e.g. when overtaking) without having to depress the accelerator
pedal fully into the kickdown range. The or iginal programme will be reactivated to
match your particular styl e of driving once the gearbox has shifted up again.
When driving in hilly regions, the gears are selected to match uphill and downhill
sections. This avoids the gearbox frequently shifting up and down when negotiating an
uphill stretch. When driving downhill, it is possible to shift down into the Tiptronic
position, in order to exploit the engine brake torque.

Seat belts

The speed of the vehicle is, nevertheless, the most important factor. Doubling the
speed of the vehicle from 25 km/h up to 50 km/hour increases the kinetic energy four
times.
The common opinion that it is possible to su pport your body in a minor accident with
your hands, is incorrect. Even in a collision at only a low speed, the forces acting on the
body are such that it is no longer possible to support your body.
Even if you only drive at a speed within the range from 30 km/hour to 50 km/hour, the
forces which are produced on your body in the event of an accident can easily exceed
10.000 N (Newton). This equals a weight of one tonne (1 000 kg).
In the event of a frontal collision, occupant s of the car not wearing a seat belt, are
thrown forward and strike in an uncontrolled way parts of the interior of the car, such
as steering wheel, da sh panel, windscreen, page 113, fig. 106 . The occupants of a
vehicle who have not fastened their seat belts may even be thrown out of the vehicle.
This can result in fatal injuries.
It is also important that rear seat occupants fasten their seat belts as they will otherwise
be thrown through the vehicle in an uncontr olled manner in the event of an accident
A rear seat passenger who has not fastened the s eat bel t i s a dang er not o nl y to hims elf
but also for those seated at the front page 113, fig. 106 on the right.Important safety information regarding the use of seat beltsThe correct use of the seat belts cons iderably reduces the risk of injury!
WARNING

The belt webbing must not be jammed in-between at any point or twisted,
or chafe against any sharp edges.

It is important that the belt webbing is properly routed if the seat belts are
to offer their maximum protection page 115, “How are seat belts correctly
fastened?”.

No two persons (also not children) should ever use a single seat belt
together.

The maximum protection which seat belts can offer is only achieved if you
are correctly seated page 110, “Correct seated position”.

The belt webbing must not run across solid or fragile objects (e.g. specta-
cles, ball-point pens, keys etc.) as this may be a cause of injuries.

Bulky, loose clothing (e.g. a winter coat over a jacket) does not allow you to
be correctly seated and impairs proper operation of the seat belts.

It is prohibited to use clamps or other objects to adjust seat belts (e.g. for
shortening the belts for smaller persons).

The lock tongue should only be inserted into the lock which is the correct
one for your seat. Wrong use of the safety belt will reduce its capacity to protect
and the risk of injury increases.

The seat backrests must not be tilted too far to the rear otherwise the seat-
belts can lose their effectiveness.

The belt webbing must always be ke pt clean. Soiled belt webbing may
impair proper operation of the inertia reel  page 157, “Seat belts”.

The slot of the belt tongue must not be blocked by paper or similar objects
otherwise the belt tongue will not lock in place properly.

Inspect the seat belts regula rly to ensure they are in good condition. If you
find seat belts which have damage to the belt, the seat belt connections, to the
inertia reel or to the lock, the relevant safety belt must be replaced by a
specialist garage.

The seat belts must not be removed or changed in any way. Do not make an
attempt to repair the seat belts yourself.

Damaged seat belts which have been subjected to stress in an accident and
were therefore stretched, must be replaced - this is best done by a specialist
garage. The anchorage points of the belts must also be inspected. The
anchorage points for the belts should also be checked.

In certain countries it is possible to use seat belts which differ in terms of
their operation from the seat belts which are described on the pages which
follow.WARNING (continued)


It is essential to always switch off page 124, “Deactivating airbags” the
front passenger airbag when attaching a child safety seat on the front
passenger seat where the child is seated with its back facing in direction of
travel (in some countries also when the child is facing the direction of travel). If
this is not done, there is a risk of the ch ild suffering severe or even fatal injuries
if the front passenger airbag is deploy ed. In certain countries national legal
provisions also require that the side or head passenger airbags be deactivated.
When transporting a child on the front passenger seat, please comply with the
appropriate national regu lations regarding the use of child safety seats.

There must not by any further persons, animals or objects positioned
between the front seated occupants and the deployment area of the airbag.

The steering wheel and the surface of the airbag module in the dash panel
on the passenger side must not be stuck onto, covered or modified in any other
way. These parts should only be cleaned with a dry cloth or a cloth moistened
with water. No objects such as cup holders, mobile phone mounts, etc. may be
attached to the covers of the airbag modules or be located within the imme-
diate area.

No modifications of any kind may be made to parts of the airbag system.
Any work on the airbag system including installing and removing system
components because of other repair wo rk (e.g. removing the steering wheel)
must only be carried out by a specialist garage.

Never carry out changes on the front bumper or on the body.

Never place any objects on the surface of the dash panel on the front
passenger side.
Side airbags*Description of side airbags
The side airbag increases protection of the passenger concerned in the
case of a side impact.The side airbags are housed in the upholstery of the seat backrests of the front seats
and are marked with the lettering “AIRBAG” fig. 113 on the middle part.
The side airbag system in combination with the three-point seat belts, offers additional
protection for the upper area of the body (chest, stomach and pelvis) in the event of
severe side collisions  in “Important safety information on the side airbag” on
page 122.
Apart from their normal protective function, a further task of the seat belts is to also
hold the driver and front pass enger in a correct seated position in the event of a side
collision so as to enable the side ai rbags to offer the maximum protection.
You should therefore always fasten the seat belts, not only because this is required by
law, but also for safety reasons and for your own protection page 113, “Why seat
belts?”.

Changes to vehicle (e.g. on engine, on th e brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the ESP page 179, “Accesso-
ries, changes and replacement of parts”.
Traction control system (TCS)*
The traction control system prevents the driven wheels from spinning
when accelerating.General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate and
climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when th e 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 surface is auto-
matically adapted by reducing the engine speed. The system operates at all speeds.
The TCS operates in combination with the ABS page 136, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system.
Switching off
You can switch the TCS off and on again as you wish by pressing the button fig. 126 .
The TCS warning light lights up in the instru ment cluster when the TCS is switched off   page 30. 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 vehicle when it has become stuck.
then you should switch on the TCS again.
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 problem-free
operation of the TCS. Differing rolling circum ferences of the tyres can lead to an unde-
sirable reduction in the engine output.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the TCS page 179, “Accesso-
ries, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prev ents an individual wheel from slip-
ping.Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to st art off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.

Operating principle
The EDL is activated automaticall
y, that is without any action on the part of the driver.
It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should
only one drive wheel begin spinning on a slippery surface there will be an appreciable
difference in the speed of the driven wheels. The EDL function brakes the slipping
wheel and the differential transmits a greater driving force to the other driven wheel.
This control process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually severe stresses exist in order to avoid
excessive heat generation in the disc brake on the wheel which is being braked. The
vehicle can continue to be driven and has the same characteristics as a vehicle not
fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING

Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. The driven wheels might still spin despite
the EDL and affect the stability of the vehicle - risk of an accident!

You should always adapt your style of driving to the condition of road
surface and to the traffic situation even when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than
otherwise - risk of an accident!Note

If the ABS or TCS or ESP warning light comes on, this may also indicate a fault in the
EDL. Please have the vehicle inspected as soon as possible by a specialist garage.

Changes to vehicle (e.g. on engine, on th e brakes, on chassis or another combina-
tion of tyres and wheels) can in fluence the function of the EDL page 179, “Accesso-
ries, changes and replacement of parts”.
BrakesWhat has a negative effect on braking efficiency?Wear-and-tear
Wear-and-tear to the brake pa ds 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 insp ected 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 un der certain conditions
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.
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated with road salt if you have not used the brakes
for some considerable time beforehand. The layer of salt on the brake discs and brake
pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been
parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firm ly applying the brakes at a fairly high
speed if you do not make much use of the braking system or if surface corrosion is
present .
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the brake
pedal can be depressed further, it is possib le that a brake circuit of the dual-circuit
brake system has failed. Drive, in such cases, to the nearest specialist garage without
delay in order to have the problem rectified. Drive at a reduced speed while on your
way to the dealer and adapt your style of driving to the higher brake pedal pressure
required.

WARNING

The ABS can also not overcome the physical limits of your vehicle. Please do
not forget this, particularly when driving on icy or wet road surfaces. If the ABS
is operating within the control range, adapt your speed immediately to the
conditions of the road surface and the traffic situation. The increased safety
offered by the ABS must not tempt you to take greater risks than otherwise -
risk of an accident!

The normal braking system is still fully functional if there is an ABS fault.
Visit a specialist garage as quickly as poss ible and adjust your style of driving to
take account of the ABS fault in the meantime since you will not know the extent
of the fault and in how far the braking efficiency is affected.Note

A warning light comes on if a fault occurs in the ABS system
  page 31.

Changes to vehicle (e.g. on engine, on th e brakes, on chassis or another combina-
tion of tyres and wheels) can in fluence the function of the ABS page 179, “Accesso-
ries, changes and replacement of parts”.
Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the
braking force and thus makes it possible to rapidly produce the pressure required in
the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations, but
do not depress the brake pedal with sufficient pressure. Consequently, it is not possible
for the vehicle to achieve its maximum deceleration and the vehicle covers a greater
distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such
cases, a much greater braking pressure exists than during a normal brake application.
This makes it possible, even with a relative ly low resistance of the brake pedal, to
produce an adequate pressure in the brake system in the shortest possible time, which
is required for maximum deceleration of th e vehicle. You must apply the brake pedal
firmly and hold it in this position in order to achieve the shortest possible braking
distance. The Brake Assist is able to help you achi
eve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of the
Brake Assist is automatically switched off and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist
function is also not available. Further information on the ESP page 133.
WARNING

The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.

Adapt your speed to the conditions of the road surface and to the traffic situ-
ation.

The increased safety offered by the Brake Assist must not tempt you to take
a greater safety risk than otherwise.
Uphill Start Assist*The uphill start assist makes it easier to start off on steep hills. The system assists a start
off by holding the brake pressure produced by the brake pedal actuation for approx. 2
seconds after releasing the brake pedal. The driver can therefore move his foot from
the brake pedal to the accelerator pedal and start off on the slope, without having to
actuate the handbrake. The brake pressure drops gradually the more you operate the
accelerator pedal. If the vehicle does not start off within 2 seconds, it starts to roll back.
The uphill start assist is active as of a 3% slope, if the driver door is closed. It is always
active on slopes when in forward or reverse start off. When driving downhill, it is
inactive.Electrohydraulic power steeringThe power steering enables you to steer the vehicle with less physical force.
The steering characteristics can be changed by a specialist garage.
