D/S - Normal position for driving forward
In the D/S position, the transmission can be
operated either in the normal D mode or in
the S sport mode . To select the S sport mode,
pull the selector lever back briefly. Pulling the
lever back again will select the normal D
mode. The instrument cluster display shows
the selected driving mode.
In the
normal mode D , the transmission auto­
matically selects the best gear ratio.
It de­
p ends on engine load, vehicle speed and the
dynamic control program (DRP).
Select the
sport mode S for sporty driving.
The vehicle makes full use of the engine's
power. Shifting is more noticeable when accel­
erating.
When the vehicle is stationary or at speeds
below 3 mph (5 km/h), you must always apply
the foot brake before and while moving the
lever to
D/S out of N .
In certain circumstances it may be advanta­
geous to temporarily switch to the manual
shift program to manually select gear ratios .,..

Floor mats used in your vehicle must be at ­
tached to these fast eners. Proper ly securing
the floor mats will prevent them from s lid ing
into positions that could interfere with the
pedals or impair safe operation of your vehicle
in other ways .
A WARNING
Pedals that cannot move freely can resu lt
in a loss of veh icle contro l and increase the

- Always make sure that floor mats are
properly secured.
- Never place or install floor mats or o ther
floo r coverings in the veh icle that cannot
be properly secured in pla ce to prevent
them from slipping and inte rfering w ith
the pedals or the ability to control the
vehicle.
- Never place o r inst all floo r ma ts or o ther
floo r coverings on top of already insta l­
led floor mats. Additional floor mats and
other coverings wi ll reduce the size of
the pedal a rea and interfere with the

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic stabilization
program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESP detects
Intelligent technology 189
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and he lps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
lf.1 in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations.
It is important to remem­
ber that ESP cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESP may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESP cannot perform the same
way it would on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESP cannot always deal as effectively
with difficu lt driving situations than at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffi<; and weather conditions. ESP can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESP improves the
possibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .

Q & .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if cor­
rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
f irmly a few times from a moderately high
speed

WARNING
- You should perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too often . This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads without using your brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 201
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system .
Safety chains
Alw ays use saf ety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra iler lights must meet all reg ulations . Be
su re to check with your Audi dea ler fo r cor re ct
wir ing, swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must i nsta ll ext ended mir rors . It is important
t h at you
always have clea r vis ion to the rear .
.8, WARNING

Afte r removing the trailer hit ch, do no t
s tore i t in yo ur vehicle . In case of sudden
b raking, the h itch cou ld fly forwar d an d in­
ju re you or yo ur passengers .
Operating instructions
Maximum trailer weight

cl ass 1 or class 2 tra ile r.
Trailer load distribution
B e sure the loa d in the tr aile r is held secure ly
i n place to p reven t it from shift ing forw ard,
ba ckward or sideways.
Never allow a passenger to ride in a trailer

Engine cooling system
Towing a trailer makes the engine work hard­
er . It is impo rtant that the cooling system's
perfo rmance is up to the additional load .
Make sure that the coo ling syst em has enough

side B-pillar (visible when the door is open).
Inflate trailer tires to trai ler and t ire manufac ­
turers' specif ications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety
chains, make sure they wi ll not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following:
.. Do not tow a loaded trailer when your car it­
self is not loaded.
.,. Be especia lly careful when passing other
ve­
hicles.
.. Observe speed limits .
.. Do not drive at the maximum permissible
speed.
.. Always apply brakes early .
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at
very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con­
trol. This means that the tow vehicle should
be loaded to the extent poss ible and permissi­
ble, while keeping the trailer as light as possi­
ble under the circumstances . Whenever possi- ble,
transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tong ue load requirements and vehicle loading
considerations.
Speed
T he higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed . Re­
duce your speed
even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill.
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of swaying.
Do not
try to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds
for vehicles towing trai lers are lower than for
regular vehicles .
Always apply brakes early. When driving
downhi ll, shift into a lower gear to use the en­
gine braking effect to s low the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefu lly. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the d isplay turn on .
For more information about indicator lights,
refer to. ¢
page 16 .
A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi.
Trailer towing tips
Important to know
Your vehicle handles differently when towing
a trai ler because of the additional weight and ..,.

244 Tires and wheels -Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your ve­
hicle's placard (tire inflation
pressure label)
¢ page 239,
fig. 178.
2. Determine the combined
weight of the driver and pas­ sengers that will be riding in
your vehicle.
3. Subtract the combined
weight of the driver and pas­ sengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the sticker
¢ page 239, fig. 178.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five
150
lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is
650 lbs. (1400-7 50
(5
X 150) = 650 lbs.)
5. Determine the combined
weight of luggage and cargo being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step
4.
6.
If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­ duces the available cargo
and luggage load capacity of
your vehicle.
... Check the tire sidewall
(¢page 246, fig. 182) to de­
termine the designated load rating for a specific tire.

• Move select or lever to p osition P q ,& .
• If you are towing a trailer, unhitch the trail­
er from your veh icle.
• Take the
jack and the spare t ir e out of the
luggage compartment

A WARNING
You or your passengers cou ld be injured
while changing a whee l if you do not fol­
low these safety precautions:
- If you have a f lat t ire, move a safe dis­
tance off the road. Turn off the eng ine,
turn the emergency f lashers on and use
other warning devices to alert o ther mo­
torists.
- Make su re that passengers wait in a safe
pla ce away from the ve hicle and well
away from the road and traffic.
- T o help preven t the veh icle from mov ing
sudden ly and possibly slipping off the
jack, always fully set the parking brake
and block the whee l diagonally opposite
the wheel being changed . When one
front wheel is lifted off the ground, plac­
ing the Automat ic Transm iss ion in "P"
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the ground is level and fi rm. If necessa ry,
use a sturdy board under the jack.
- After installing the spa re wheel, make
sure that you replace the flat tire/whee l
in its sto rage area properly and tighten
the kn u rled re taining screw securely.
