T he manual transmission in your Audi is
equipped with an
interlock-feature.
~ Depress the clutch pedal all the way.
~ Start the eng ine 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.
- The back-up lights go on when you shift
into Reverse w ith the ignition on.

Introduction
Applies to vehicles: with multitronic/S tronic/tiptronic
The automatic transmission is controlled elec
tronically. The transmission upshifts or down
shifts automatically depending on which drive
program is selected .
When a
moderate driving style is used, the
transmission selects the most economical
driving mode. It will then change up early and
delay the downshifts to give better fuel econ
omy .
The transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac
celerator pedal movements, heavy accelera
t ion, frequent changes in speed and trave ling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode)~ page 93 .
Various automatic transmissions may be in
stalled, depending on the model:
multitronic transmission
The multitronic transmission is a continuously
variable transmission. Power is transferred us
ing a multidisk clutch. In contrast to conven
tional automatic transmissions using shifting
operations, the transmission ratio in the con
tinuously var iable transmission is changed
continuously . This optimizes the comfort level
and conserves fuel.
S tronic transmission
The S tronic is a dual-clutch transmission .
Power is transferred using two clutches that
work independently from one another_ They
replace the torque converter used in conven
tiona l automatic transmissions and allow the ..,_

distance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other drive
wheel or whee ls if the vehicle is equipped with
a ll-wheel drive* . This function is not avai lab le
at higher speeds.
I n extreme cases , EDL automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating . EDL wi ll switch on again au
tomatically when conditions have returned to
normal.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering torque.
In vehicles with dynam ic steeri ng*, ESC also
he lps to stabilize the stee ring in critical s itua
tions.
Electronic interaxle differential lock* /
selective wheel torque control*
The electronic interaxle d ifferential lock (front
wheel drive) or the select ive wheel torque
con trol ( all wheel d rive) oper ates when driving
through curves . The front whee l on the inside
of the cu rve or both whee ls on the inside of
the curve are b raked se lectively as needed.
This a llows more prec ise driving in c urves. The
applicable system may not activate when driv ing i n wet or snowy conditions.
A WARNING
- The ESC and its integrated systems can
not overcome the laws of physics. This is
especially important on slippery o r wet
roads . If the systems begin acting to sta·
b iliz e your veh icle, you s hou ld immed i
a tely c ha n ge your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will increase the risk of a loss of vehi
cle control, collision and serious personal
inj uries.
-Always adapt your speed to road, traffic and weather conditions. The risk of los
ing control of the vehicle increases when
d riving too fast, espec ially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. The ESC a nd its integrated sys
tems canno t always p reven t collisions -
there is still a risk of acc idents!
- Always accelera te wi th spe cial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al
ways he lp to red uce the risk of loss of ve
h icle control.
(D Tips
- ABS and ASR only work cor rectly when
all four wheels are equipped with identi
cal tires. D ifferent tire sizes can lead to a
reduction in engine power .
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator light
DJ or ml (USA
mode ls)l iiJ (Canada models) appears,
there may be a malfunction<=>

overheat re ducin g the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near est author ized Audi dealer or qualified
workshop .
- Never let the vehicle ro ll to a stop w ith
the engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed conside ra
bly harder to make up for the lac k of
booster assistance.

256 Tires and wheels
be fitted over the wheel bolts. These are
available from authorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi
cle or installing them incorrectly can in
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in
structions provided by the snow chain
manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations .
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily .
- Snow chains, which come into direct con
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to
vehicles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
corr ect torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
secu rely and that the b rake system functions
correctly . In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model ¢
page 285.
A WARNING "--
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in
jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on your
vehicle.
- Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is moving. If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be
come loose.
Q) Note
The specified torque for the wheel bolts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work
shop .
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel ..,.
