way before you can start the engine .
The manual transmission in your Audi is
equipped with an
interlock-feature.
• Depress the clutch pedal all the way.
• Start the engine with the gearshift lever in
Neutral and the clutch pedal depressed.
(D Note
Always depress the clutch pedal fully when
changing gears. Do not hold the vehicle on
a hill with the clutch pedal partially de­
pressed. This may cause premature clutch
wear or damage .
@ Tips
-Resting your hand on the gearshift lever
knob while driving will cause premature
wear in the transmission.

S tronic transmission
· Introduction
Applies to vehicles: with S tronic®
Your vehicle is equipped with a S tronic trans­
mission, also called a double-clutch system/
transmission .
Power is transferred between the engine and
the transmission by means of two independ­ ent clutches. They replace the torque convert­
er of conventiona l automatic transmissions
and allow the vehicle to accelerate without a
not iceable break in the power flow.
With the aid of
tiptronic, the gears can op­
t ionally be shifted
manually ~ page 100.
Selector lever positions

@ Tips
-Where snow chains are mandatory on
certain roads, this normally also applies
to vehicles with All Wheel Drive .
- If snow chains are insta lled, the tire
pressures shou ld not be stored in the tire
pressure monitoring system (TPMS).
Otherwise the system could malfunction
¢page 232.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts wit h the right
length and correctly s haped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the bra ke system f unctions
cor rectly .
In certain circumstances, you may not use
wh eel bolts from a differ ent vehicle -even if it
i s the same mode l.
.&, WARNING
Improperly tig hte ned o r maint ained wheel
bol ts can become loose ca using loss of
cont ro l, a co llision and ser ious persona l in ­
jury.
- Always keep the wheel bolts an d the
threads in the wheel hubs clean so the
whee l bolts can tu rn easily and be pro p­
er ly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the w heel hubs. They can
become loose w hile driving if greased or
o iled, even if tightened to the specified
torq ue.
- Only use wheel bolts t hat belong to the
r im being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tighten ing
torq ue for the wheel bo lts t o reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 229
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as so on as possible with a
torq ue w rench -prefe rably by an au thor ­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng u nder a var iety of driving condi­
tions . Ask your au thorized Aud i dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numera l represen ts the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in perce ntage. Conven­
tiona l tires have a he ight/w idth ratio of 60 o r
more.
The performance of low-a spect-ratio tires i s
particularly sensitive to improper inflation
pre ssure.
It is therefore important that low
aspect ratio tires are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 218, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
