Steering recommendation
The ESC helps to stabilize the veh icle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv
i n g on curves . The front wheel on the inside of
the c urve or both wheels on the inside of the
curve are braked selectively as needed. This al
lows more precise driving in curves.
Automatic post-collision braking system
The "Automatic post-collision brak ing system"
can help to reduce the r isk of slid ing and of other
coll is ions after an accident . If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if :
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi-
Switching on and off
cal laws. This is especially important on slip
pery or wet roads. If the systems beg in act
ing to stabilize your vehicle, you should im
mediately alter your speed to match the
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
- Please note the risk of a collision increases
when dr iv in g fast, especially through curves
and on slippery or wet roads, and when dr iv
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre
vent collisions -there is still a risk of acci
dents!
- Press the accelerator peda l carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal
led and this can affect driving stability and
increase the risk of a collision .
@ Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc
tion in engine power.
- You may hear noises when the systems de
scribed are working.
£SC turns on automatically when you start the engine .

The ESC is designed to function in levels. Depend
i ng on the level that is selected, the stabilization
function of the ESC is limited or switched off. The amount of stabilization control will differ de
pending on the level.
The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Dr iving in deep snow or on loose ground

Trailer mod e
Trailer mode
Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trailer, please remember that
the additional load will affect durability, economy and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Tr aile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your veh icle and trailer and must be mounted
securely on the vehicle's chassis at a technically
sound
location . Use only a trailer hitch with a re
movable ball mount . Always check w ith the t rail
er hitch man ufact urer to make su re that you are
using the co rrect hitch .
Do not use a bump er hit ch .
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system. No mod ificat ions should be
made to the vehicle exhaust and brake systems .
From t ime to t ime, check that a ll hitch mount ing
bolts rema in securely fastened.
When you are not tow ing a tra iler, remove the
tra iler hitch ba ll mount . This prevents the hitch
from caus ing damage shou ld your veh icle be
s truck from be hind ¢
,&..
Trailer brakes
If your trailer is equipped with a brak ing system,
check to be sure that it conforms to all regula
tions .
164
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢&. .
Safety chains
Always use safety chains between you r vehicle
and the trailer.
Trailer lights
Traile r lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor
r ec t wiring , switches, and relays.
M irrors
If you are unable to see the traffic behind you us
ing the regular outs ide mirrors, then you
must in
stall extended mirrors . It is important that you
always have clear vision to the rear.
.&_ WARNING
- If a tra ile r has e lectr ica l brakes p lease no te
t hat these brakes are not activated by the
factory-fit ted contro l unit -risk of accident!
- After removing the trai ler hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch co uld fly forward and in
jure you or yo ur passengers.
- Never install a "we ight distribu ting" or
"load eq ualizing" trailer hitch on your vehi
cle. The vehicle was not designed for these
kinds of trailer hitches. The hitch attach ment can fail, caus ing the tra iler to tear
loose from the vehicle.
- The Gross Vehicle Weight Rating for your
veh icle, found on the safety compliance la
be l on the driver's s ide B-pillar, must never
be exceeded under any circumstances . Ex
ceed ing the Gross Vehicle Weight Rat ing of
your veh icle is likely to damage yo ur vehicle,
and such damage will not be covered by
your Limited New Vehicle Warranty . Exceed
ing the Gross Vehicle Weight Rating will al
so change the performance and handling
characteristics of your vehicle, which could
cause a crash result ing in serious injury or
death.

Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only ofter doing the following:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the ve
hicle and the trailer wheels .
.. With chocks in place, slowly release the brakes
until the wheel chocks absorb the load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to P.
When restarting after parking:
.. Apply the foot brake .
.. Start the engine .
.. Move the selecto r lever to D/S .
.,. Release the parking brake and slowly pull out
and away from the wheel chocks .
.. Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector lever of the automat
ic transmission to P before applying the park
ing brake and before blocking the wheels, you
may have to use more force later to move the
lever out of the P position.

Checking and Filling
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance.
Fig. 153 Eng ine compartment: Cover on the brake fluid
r eservoir
Before you check anything in the engine compart
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 177.
., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 153, ¢page 179, fig . 149 . The
brake fluid level must be between the
" MIN"
and "MAX " markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the left
side ¢
page 179 .
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm .
If the brake fluid level falls
considerably below
the ' 'MIN" mark, the brake warning/indicator
light (USA models:
1111 , Canada models:. )
will come on¢
page 13 . Do not continue to oper
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or qualified workshop and the cause
corrected. If the brake fluid level is too low, the
brake warning/indicator light w ill illuminate.
Contact an author ized Audi dealer
immediately.
(D} Tips
The brake fluid reservoir is located under
neath the cover.
186
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor
rosion in the brake system may result after ape
riod of time . The boiling po int of the brake fluid
will a lso decrease considerably and decrease
braking performance.
Therefore , the brake fluid must be changed
every
two years .
Always use new brake fluid which con
forms to Feder-al Motor Vehicle Standard "FMVSS
116 DOT 4 ".
The brake fluid reservoir can be difficult to reach ,
therefore, we recommend that you have the
brake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro
priate brake fluid. Observe these precau
tions:
- Use only brake fluid that meets SAE speci
fi cation
J 1703 and conforms to Federal
Motor Veh icle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid .
The correct type of brake f luid is also indi
cated on the brake fluid reservoir.
- The brake fluid must be new . Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long .
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-
cle .
lilJJ,

@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as we ll as the special toots re
quired and the necessary expertise, we rec
ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro
lyte level checked by an authorized Audi dealer or
qualified workshop. The electrolyte level should
also be checked each time the battery is charged
c> page 189.
Have the battery checked when you take your ve
hicle in for serv ice. You are well advised to re
place a battery t hat is older than 5 years.
With certain types of airbag deployment, the battery is disconnected from the vehicle electri
cal system for safety reasons
c> & in Repair, care
and disposal of the airbags on page 125 .
Disconnecting the battery terminals
Some vehicle functions (power window regula
tors, for example) are lost if the battery termi nals are disconnected. These functions have to be
relearned after the battery terminals are con
nected again. To prevent th is, the battery should
only be disconnected from the vehicle e lectr ica l
system when abso lutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and maintains starting ca
pability over a longer pe riod
c> page 157.
Some of the conven ience functions may not oper
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available again when you turn on the ignition and
start the engine.
Checking and Filling
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is be
cause more power is also consumed while start
ing, and the headlights, rear window defogger,
etc., are used more often.
Avo id unnecessary power consumption, particu
larly in city traffic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in
c> page 189. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve
hicle battery should be removed and stored
where it w ill not freeze. This will prevent it
from be ing damaged and having to be re
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the engine compart
ment . Before you check anything in the engine
compartment ,
read and heed all WARNINGS
c>,& ,
Always heed the safety warnings, when working
on the vehicle battery or the veh icle electrical
system to prevent injury.
The following WARNINGS are very important
when working on the battery:
Always heed the following WARNING SYM·
BOLS and safety precautions when working on
the battery.

different tire speeds. For this reason, in case of emergency, only
use a spare tire that has the same
circumference as the regular
tires.
&_ WARNING -
-Only use tire/rim combina tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle . Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
Wheels
-Only use tires that are more
than 6 years old when abso lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve
hicle damage or accidents.
- If you install wheel covers on
the vehicle, make sure they al low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys
tem is not operating properly. The TPMS mal
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunct ion, the telltale will flash for approxi
mately one minute and then remain continuous ly
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal
function exists.
When the malfunction indicator is illuminated,
the system may not be ab le to detect or signal
low tire pressure as intended . TPM S malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
