Air recirculation mode
Air recirculation mode D
on (a lamp lights up in red) prevents strong
odours from the outside air from entering in the vehicle, for example when
passing through a tunnel or in a traffic jam ⇒
.
When the outside temperature is low, air recirculation mode improves heat-
ing performance by heating air from the interior instead of cold air from the
outside.

132Air conditioning
● The outside temperature is below +3°C.
● The air conditioning system compressor has been temporarily switched
off because of an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioning checked by a spe-
cialised workshop.
Air recirculation
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.
When air recirculation mode is switched on (button ⇒ Fig. 94
with warn-
ing lamp) strong odours in the outside air do not enter the vehicle interior,
for example when passing through a tunnel or in a traffic jam.
When the outside temperature is low, air recirculation mode improves heat-
ing performance by heating air from the interior instead of cold air from the
outside.
When the outside temperature is high, air recirculation mode improves cool-
ing performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, the air recirculation should not be switched on when the
air distribution control is set to the windscreen setting .
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioner is switched off, the windows can quickly
mist over. Therefore, never leave the air recirculation mode switched on
for a long time (risk of accident).
Note
● When engaging reverse gear, the air recirculation is connected automat-
ically to prevent the entrance of exhaust gases in the vehicle on travelling
backwards. The control lamp on the button
does not light up.
● If the temperature control is turned to the coldest setting (blue point)
and the switch AC
is activated, the “Air recirculation” function is automati-
cally activated in order to cool the vehicle rapidly using less energy; its
function control lamp will light.
● If the function is not deactivated by pressing the button, this will deacti-
vate after approx. 20 min.
Economic use of the air conditioning
When the air conditioning is switched on, the compressor consumes engine
power and has influence on fuel consumption. Consider the following
points in order to have the system operating in the minimum possible time.
● If the vehicle interior has overheated due to an excessive solar radiation,
it is best to open the windows or doors to allow the hot air to escape.
● While in motion, the air conditioning should not be switched on if the
windows or the sunroof are open.*

134Air conditioning
Automatic mode
In automatic mode air temperature, air flow and distribution
are automatically regulated so that a specified temperature
is attained as quickly as possible, and then maintained.
Switching on automatic mode
– Press the button AUTO
. The indication
⇒ Fig. 95 3 is dis-
played.
– Press keys 10
and 11 ⇒ Fig. 95 to adjust the desired tempera-
ture inside the vehicle. We recommend you adjust the tempera-
ture to 22°C (72°F).
A comfortable interior climate is quickly reached when a temperature of
22°C (72°F) is set in automatic mode. Therefore, we recommend you not to
change this adjustment, except as necessary to suit individual preferences
or particular circumstances. The inside temperature can be set between
+18°C (64°F) and +29°C (86°F). If a lower or higher temperature is selected,
LO or HI are respectively displayed on the screen. These are approximate
temperatures which may slightly vary depending on the outside conditions.
Climatronic maintains a constant temperature. To do so, it automatically
regulates the supplied air temperature, the blower speed and the air distri-
bution. The system also considers the sunlight radiation, so there is no
need for manual readjustment. Therefore, automatic mode almost always
provides the best comfort for the vehicle occupants throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for air distribution or blower. The temperature continues to self-reg-
ulate. Manual mode
In manual mode the air temperature, flow, and the desired
air distribution can be adjusted.
Switching on manual mode
– Press one of the buttons ⇒ Fig. 95 14
to 16 or press the blower
control 8 and 9 down. The indicator is switched off 3.
Temperature
The inside temperature can be set between +18°C (64°F) and +29°C (86°F).
These are approximate temperatures which may slightly vary depending on
the outside conditions.
If a temperature below 18°C (64°F), is selected, the display switches to LO In
this setting the system runs at maximum cooling output and the tempera-
ture is not regulated.
If a temperature above 29°C (86°F) is selected, the display switches to HI In
this setting the system runs at maximum heating output and the tempera-
ture is not controlled.
Blower
The blower can be adjusted with buttons 8
and 9 ⇒ Fig. 95. If the blower
is off (level 1 is not shown on the screen) and button 9 is pressed after 1
second, the Climatronic switches off.
Air distribution
The air distribution is adjusted using the buttons
, and . It is also
possible to open and close some of the air outlets separately.
Switching the air conditioning on and off
Pressing the button AC
the air cooling system can be switched off in order
to save fuel. The temperature continues to self-regulate. The set tempera-
ture can then only be reached if it is higher than the outside temperature.

Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside. – Press the button
to switch air recirculation mode on or off.
This is ON if the symbol ⇒ Fig. 95 is displayed on the screen.
Air recirculation mode prevents strong odours in the ambient air from enter-
ing the vehicle interior, for example when passing through a tunnel or in a
traffic jam.
When the outside temperature is low, air recirculation mode improves heat-
ing performance by heating air from the interior instead of cold air from the
outside.
When the outside temperature is high, air recirculation mode improves cool-
ing performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, the air recirculation should not be switched on when the
air distribution control is set to the windscreen setting .
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioner is switched off, the windows can quickly
mist over. Therefore, never leave the air recirculation mode switched on
for a long time (risk of accident).
Note
When engaging reverse gear, the air recirculation is connected automatical-
ly to prevent the entrance of exhaust gases in the vehicle on travelling back-
wards. In this case the symbol
for air recirculation is not displayed. General notes
Pollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the specified intervals in the Maintenance Programme.
If the filter loses efficiency prematurely due to use in areas reaching very
high pollution levels, the pollen filter must be changed more frequently
than stated in the Service Schedule.
CAUTION
● If you suspect that the air conditioner is damaged, switch it off with but-
ton AC
to prevent further damage and have it checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised
workshop.
Note
● If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a pud-
dle underneath the vehicle. This is completely normal and there is no need
to suspect a leak.
● Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over.
● The air from the vents flows through the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects.

Automatic gearbox*
Gearbox programmes
The automatic gearbox has got two gearbox programmes.
Fig. 103 Automatic gear-
box
Selecting the normal programme
– Put the selector lever into position D.
Selecting the sport programme
– Put the selector lever into position S.
If you select the normal programme, D, you will drive in the economy mode,
i.e. the programme is designed to reduce fuel consumption. The gearbox
changes up into a higher gear as soon as possible and down into a lower
gear as late as possible.
If you select the sport programme, S, you will drive in a sporty mode, i.e. a
programme in which shifts into high gears are postponed in order to use
the full power of the engine. Selector lever lock
The selector lever lock in position P or N prevents gears from
being engaged inadvertently, which would cause the vehicle
to move.

Changing gear in tiptronic mode
– Press the selector lever from position D to the right into the tip-
tronic selector gate.
– Lightly press the selector lever forward + to change up into high
gears.
– Lightly press the selector lever backwards - to change down into
low gears.
Changing gear with the steering wheel paddle levers*
– Press the right paddle lever +
towards the steering wheel to
change up ⇒ Fig. 108.
– Press the left paddle lever –
towards the steering wheel to

Using the paddle levers on the steering wheel, you can access manual driv-
ing mode regardless of the pre-selected driving mode.
General information about driving in tiptronic mode
When accelerating, the automatic gearbox / DSG automatic gearbox goes
into a higher gear a little before the engine reaches its maximum permitted
revolutions.
If a lower gear is selected, the automatic gearbox / DSG automatic gearbox
will only change down when the engine cannot go over its maximum permit-
ted revolutions.
If tiptronic is selected whilst the vehicle is in motion and the automatic
gearbox / DSG automatic gearbox is in third gear and selector lever position
D, tiptronic mode will then also be in third gear. Changing gears in the normal or sport programme using the steering wheel
paddle levers
If the paddle levers
⇒ Fig. 108 are used in the normal or sport programme,
the system switches temporarily to tiptronic mode. To exit “tiptronic” mode
again, press the right paddle lever +
towards the steering wheel for approx-
imately one second. You will also leave tiptronic mode if the paddle levers
are not moved for a certain time.
Note
● The gear paddle levers on the steering wheel can be operated with the
selector lever in any position and with the vehicle in motion.

WARNING
● If you do not start the vehicle immediately after taking your foot off
the brake pedal, the vehicle may start to roll back under certain condi-
tions. Depress the brake pedal or use the handbrake immediately.
● If the engine stalls, depress the brake pedal or use the handbrake im-
mediately.
● When following a line of traffic uphill, if you want to prevent the vehi-
cle from rolling back accidentally when starting off, hold the brake pedal
down for a few seconds before starting off.
Note
The Official Service or a specialised workshop can tell you if your vehicle is
equipped with this system.
Acoustic parking aid system* Rear parking aid
The parking aid system will use an audible warning to indi-
cate of the approach of any object towards the rear of the ve-
hicle. Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors loca-
ted on the rear bumper. The measuring range of the sensors starts approxi-
mately and depending on the nature of the obstacle at a distance of:
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m Activation
The system is activated by engagement of the reverse gear. A brief audible
warning confirms the activation and correct function of the system.
Reverse gear
The distance warning will begin as soon as an obstacle is detected by the
system. The frequency of the bleeps emitted by the system will increase rap-
idly as the vehicle approaches the obstacle.
Within a short distance of about 30cm, a continuous signal sounds (stop
signal). The driver should not reverse any further.
Models with a factory-fitted towing bracket: When the vehicle is less than
0.35 m away from the obstacle the warning tone will sound continuously.
The driver should then not reverse any further.
The warning tone decreases by 30% after 3 seconds from the start of the
system.
Provided that it is not in continuous mode, the tone on the parking aid sys-
tem stops when it detects a wall parallel to the vehicle.
Trailer towing
For vehicles factory-fitted with a towing bar, the parking aid system will not
be activated by the engagement of the reverse gear when pulling a trailer,
as the trailer's electric connector will be plugged into the vehicle.
Possible faults
If a continuous beep sounds for some seconds when the reverse gear is en-
gaged, this indicates that there is a fault in the parking aid system.
If the fault continues until the ignition is turned off, the audible warning of
the fault will not be emitted every time the system is reactivated (by engag-
ing the reverse gear). Thus, the system ready indication will not sound ei-
ther. Have the fault repaired by a Technical Service as soon as possible.
If there is no ready signal or no acoustic warning signal, then the parking
aid loudspeaker is faulty and may not warn of obstacles.

170Driving and the environment
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero (dis-
connection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible.
We recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the “recommended gear” indication that ap-
pears on the instrument panel ⇒ page 58.
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly
at higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at lev-
el crossings or at traffic lights with a long red phase. The fuel saved after
only 30 - 40 seconds is greater than the amount of fuel needed to restart
the engine.
The engine takes a long time to warm up when it is idling. Mechanical wear
and pollutant emissions are also especially high during this initial warm-up
phase. It is therefore best to drive off immediately after starting the engine.
Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey,
you will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary. Avoid short journeys
To reduce the consumption and emission of polluting exhaust gases, the
engine and the exhaust gas filtration systems should reach the optimum
service temperature.
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately
four kilometres (2.5 miles). This is why we recommend
avoiding short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If
the tyre pressure is just one bar too low, fuel consumption can increase by
as much as 5%. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Given that every kilo of extra weight will increase the fuel consumption, it is
advisable to always check the luggage compartment to make sure that no
unnecessary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h (60-75 mph) your vehicle
will use about 12% more fuel as a result of the extra wind resistance caused
by the roof rack even when it is not in use.
Save electricity
The engine activates the alternator, which produces electricity. With the
need for electricity, fuel consumption is also increased. Because of this, al-
ways turn off electrical components when you do not need them. Examples
of components that use a lot of electricity are: the fan at high speeds, the
rear window heating or the seat heaters*.
