WARNING
Never switch off the engine while the vehi-
cle is moving. This could cause l oss of con-
tr
ol of the vehicle, accidents and serious in-
jury.

Intr oduction Your vehicle is equipped with an electronical-
ly controlled manual gearbox. T
or
que be-
tween the engine and the gearbox is trans-
mitted via two independent clutches. They
replace the torque converter found on con-
ventional automatic gearboxes and allow for
smooth, uninterrupted acceleration of the ve-
hicle.
The tiptronic system allows the driver to
change gears manually if desired

Start and driving
Downhill speed control* The downhill speed control function helps the
driver when driving down steep gr
adients.
Do
wnhill speed control is activated when the
selector lever is in D/S and the driver applies
the foot brake. The automatic gearbox auto-
matically engages a lower gear that is suita-
ble for the slope. The downhill speed control
function attempts to maintain the speed at
which the vehicle was travelling when the
foot brake was applied (subject to the laws of
physics and technical drive limitations). It
may be necessary to adjust the speed again
using the foot brake in certain situations. Giv-
en that the downhill speed control can only
change down to 3rd gear, on very steep de-
scents the tiptronic mode may be required. In
this case, manually reduce the tiptronic to
2nd or 1st gear to use the engine brake and
reduce the charge on the brakes.
Downhill speed control is deactivated as
soon as the road levels out again or you press
the accelerator pedal.

Start and driving
Due to the greater rolling resistance, under-
infl ation al
so increases t
yr
e 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 nee-
ded. 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 re-
sistance 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 elec-
tricity, fuel consumption also increases. Be-
cause of this, always turn off electrical devi-
ces when you do not need them. Examples of
devices that use a lot of electricity are: the
blower at high speeds, the rear window heat-
ing or the seat heaters*. Note
