Air conditioning
Economic use of the air-conditioning
sy s
t
em When the air conditioning is switched on, the
compr
e
ssor consumes engine power and has
influence on fuel consumption.
If the vehicle interior has overheated due to
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 are open. If the interior temperature can be reached
without
sw
itching on the air conditioning, the
fresh air mode should be used. For the sake of the environment
Saving fuel reduces emissions. Faults
If the air conditioning does not work at out-
side t
emper
atures above +5°C (+41°F) then the system is faulty. This may be due to one
of the f
o
llowing reasons:
● One of the fuses has blown. Check the fuse
and repl
ace if necessary ››› page 80.
● The air conditioning compressor has
switc
hed off temporarily because of in-
creased engine coolant temperature
››› page 97.
If you cannot repair the fault yourself or
where cooling power continues to drop,
switch off the system. Contact a specialised
service.

The m
anual gearbox can be activated when
the vehicle is either moving or stationary.
When accelerating, the gearbox automatical-
ly shifts up shortly before the maximum en-
gine speed is reached.
On shifting up, the gear is only engaged
when there is no risk of engine damage.
When the accelerator pedal is pressed down
to the kick-down zone, the gearbox will shift
down in line with the road speed and engine
speed. Note
The kick-down function is also available in
manua l
shift mode. Selector lever lock

When the selector lever merely moves
through position N (e.g. when moved from R
to D), the lever lock is not applied. This
makes it possible, for example, to rock a
stuck vehicle backwards and forwards. The
lock is only applied if the brake is not press-
ed and the selector lever is moved to position
N for more than 2 seconds.
The selector lever only locks when the is vehi-
cle stationary or driving at a speed lower
than 5 km/h (3 mph). At a higher speed, it
automatically disconnects in the N position.
Interlock button
The interlock button on the selector lever
knob prevents the driver from inadvertently
engaging a gear. Press the button to unlock
the selector lever.

Operation
Driving programmes Your vehicle is equipped with an electronical-
ly-c
ontr
olled automatic gearbox. Shifting up
or down depends on the programme selec-
ted.
For a calm driving style, the gearbox uses the
most economic programme. The gearbox
shifts up as quickly as possible and shifts
down as late as possible, thus increasing
driving economy.
With a sporty driving style , characterised by
sudden acceleration, heavy acceleration,
speeds that often increase and decrease and
maximum speed, the gearbox adapts to this
driving style when the accelerator is pressed
down fully (kick-down) by shifting down as
quickly as possible and can even shift down
by several gears at once.
Selecting the best driving programmes is an
endless job. Regardless of this, the driver can
also make the gearbox switch to a more dy-
namic gear shift programme by pressing the
accelerator quickly. This makes the automatic
gearbox shift down into a lower gear than the
one that would normally apply to the current
speed, allowing for more rapid acceleration
(e.g. to overtake another vehicle) without
having to press the accelerator until the kick-
down position. On shifting up in a corre-
sponding driving style, the gearbox returns to
the original programme. When driving along mountain roads, the
ge
arbo
x adapts to the gradients. This avoids
having to frequently change gears when driv-
ing uphill. In Tiptronic mode, it is possible to
shift down manually when driving downhill to
use the braking effect of the engine.
Backup programme A back-up programme exists in case of faults.
In the event
of
a fault in the gearbox electron-
ics, it will continue to work in one of the cor-
responding back-up programmes. All seg-
ments of the screen are lit up or switched off.
The fault can be seen as follows:
● The gearbox only engages certain gears
● Reverse gear R cannot be en
gaged
● The manual gearbox switches off in the
back
-up programme Note
If the gearbox switches to the back-up pro-
gramme, v
isit an Authorised Service as soon
as possible to solve the problem. Gearbox malfunctions

engage a gear again.
If the fault was caused by a gearbox with a
high temperature, this driver message will be

Driving
ahead. The braking effect achieved in this
w a
y
helps to reduce the wear of brakes and
tyres; emissions and fuel consumption are
reduced to zero (disconnection due to iner-
tia).
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: shift up from first to second
gear as soon 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 24.
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 in-
crease 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 level cross-
ings 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 re-
star
t the engine.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing 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 con-
sume 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 val-
ue.
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 operating temperature.
With the engine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres (2.5 miles). This is why we recom- mend avoiding short trips whenever possi-
ble.
M
aintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi/100 kPa) too
low, fuel consumption can increase by as
much as 5%. Due to the greater rolling resist-
ance, under-inflation also increases tyre wear
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 in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing 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 km/h (62 mph)
and 120 km/h (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. »
