Functioning of Anti-Lock Brake System
(ABS}
ABS prevents the wheels from locking up under braking.
The ABS contributes effectively to vehicle control since it prevents the
w heels from
locking whe n the brakes are applied . This means t hat t he
vehicle rema ins steerable and is less likely to skid.
With ABS you do not need to pump the brake. Ju st hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance under all
circu mstances. When d riving on gr ave l o r on new ly falle n snow o n top
of icy s urfaces, braking distance may be even longer, therefore, under
t he se c ir cu mstances, i t is especially importa nt that you dr ive slowly
and with great care.
How the ABS system works
An a utomat ic check is made when a speed of about 12 mph (20 km/h)
is reached. When this happens, a pumping noise can be heard.
If an individ ual w heel beg ins to rotate too slow ly in relat ion to vehicle
speed and tends to lock, t he ABS automat ic al ly reduces brake pres­
sure to prevent t hat wheel from locking .
Thi s automatic adjustment process w ill cause a
slight vibrat ion of
t he bra ke ped al and some noises to aler t you th at vehicle s peed mus t
be adapted to existing road and traff ic conditions.
& WARNING
Although the ABS is very effective , always remember that braking
capability i s limited by tire traction . Always adjust your driving
speed acco rding to the road and traffic condition s. Do not let the
extra safety afforded by the ABS tempt you into taking extra risk s.
T he ABS cannot overcome the laws of physics .

(I] Tips
•
If ABS is no t fun ct io ni ng prope rly, a wa rning light will come on .
See
=> page 17.
• If a fault occurs in the A BS, the EDL is also not functioning . This is
indicated by t he ABS warn ing light .•
Brake assist
Brake assist is designed to achieve the optimum braking
effect.
Bra ke ass ist helps to i ncrease the effe ctive br aking power and thus to
achieve a shorte r stopping distance . If the d river presses the brake
peda l very quickly, brake assist automatically boosts the bra king
force to the max imum level, up to the po int whe re the anti-lock b rake
function (ABS) intervenes to stop t he wheels from locki ng . You
should then keep the br ake peda l pressed unti l the veh icle has braked
to the required speed . Brake ass ist switches itself off as soon as you
re le ase the br ake pedal.
& WARNING
Please remember that the accident risk always increases if you
drive too fast , especially in corners or on a slippery road , or if you
follow the vehicle ahead of you too clo sely. Increased ri sk of an
accident cannot be compensated for even by brake assist , so
alway s maintain a safe speed .•

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor ­
tation.
If yo u plan to tow a t rai ler, p lease rem emb er that the add itiona l load
wi ll affect durab ility, economy and performance.
T railer tow ing not on ly p laces mo re s tress on the vehicle, it a lso calls
for more concentrat ion from the driver.
For this reason, a lways follow the ope rating and dr iv ing instr uctions
prov ided and use common sense .
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the gross trailer weig ht.
Th e hitch mus t be suitable for yo ur vehicle a nd tra ile r and mus t be
mounted secure ly on the vehicle's chassis at a
technically sound l oca­
t ion. Use only a trailer hitch wi th a remov ab le b all m ount. Alw ays
check w ith the tra iler hitch manufacturer to make sure that you are
using t he cor re ct hi tch.
Do not use a bumper hitch.
The h itch must be installed in such a way t hat it does not interfere
w ith the impa ct-absorbing b umper system. No mod ifi cat ions sho uld
be made to the vehicle exhaust and brake systems. From time to
ti me, chec k tha t all hitc h mou ntin g bol ts rem ain secure ly f aste n ed.
When you a re not tow ing a tra iler, remove the tra iler hitch ba ll
mount. This prevents the hitc h from caus ing damage should yo ur
vehicle be struck from behind=> &.

ment Safety first Vehicle operation
Trailer brakes
If your trailer is eq
uipped with a braking system, check to be s ure that
i t confo rm s to all regula tions.
The tra iler hydraulic brake system must not be directly connected to
the vehicle's hydraulic brake system=>& .
Safety chains
Alw ays use safety chains be twee n your vehicle and the trai ler.
Trailer lights
Tr ailer l ights m ust meet all reg ulat io ns. Be su re to check with your
author ized Audi deale r for correct wir ing, switches, and re lays.
Mirrors
If you are unab le to see the traffic behind you us ing the regular
outside m irro rs, then you
must install extended m irro rs. It is impor­
tant that yo u
always have clear vision to the rear.
& WARNING
• If a trailer has electrical b rake s please note that these brakes
are not activated by the factory-fitted control unit -ri sk of acci­
dent!
• After removing the trailer hitch , do not store it in your vehicle.
In case of sudden braking, the hitch could fly fo rward and injure
you or your passengers. •
Operating instructions
Maximum trailer we ight
A trailer for your vehicle is limited to a typical class 1 or class 2 trailer . .,.
Vehicle care Do-it-yourself service Technical data

Observe speed limits. In some areas, speeds for vehicles towing
t railers are lowe r than for regular veh icles.
Always apply brakes early. When dr iv ing downh ill, sh ift in to a lower
gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge~ page 10 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditione r.
If the coolant temperature warning light in the instrument cluster
star ts flashing
-t- , pull off the road, stop and let the engine idle for
about two minutes to prevent heat bu ild-up.
& WARNING
Anyone not properly restrained in a moving 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. u
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a tra iler because of the
additiona l weight and different weight distribution. Safety, perfor ­
mance and economy will greatly depend on how carefu lly you load
your trailer and operate your rig .
Before you actua lly tow your trailer, practice turning, stopp ing and
backing up in an area away from traffic. Keep pract icing until you have
become completely familiar with the way your vehicle-t railer combi­
nation behaves and responds.
Controls and equip­ ment Safety first Vehicle operation
Backing up
is d iff icult and requ ires practice . Backing up with a trailer
generally requires steer ing action opposite to that when backing up
your vehicle without a trailer.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop . To compensate fo r the
trailer, you will need a larger than norma l turning radius.
When passing, remember that you cannot accelerate as fast as you
normally would because of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for you r
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes .
[I) Tips
• Do not tow a trai ler during the break-in per iod of your vehicle.
• If you tow a tra iler, your Audi may requi re more frequent mainte­
nance due to the extra toad~
page 340. •
Parking on a slope
Do not park on a slope with a trailer. If it cannot be
avoided, do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle 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 .

The fluid level may drop slightly after some time due to the auto­
matic adjustment of the brake pads. This is not cause for alarm.
If the brake flu id level falls considerably below the "MIN " mark, the
brake warning/indicator light (U.S. models:
BRAKE , Canadian mode ls:
{(j)) ) will come on=> page 18 and=> page 33. Do not continue to
ope rate the vehicle. The complete brake system should be thorough ly
checked by an authorized Audi dealer or qualified workshop and the
cause corrected. If the brake fluid level is too low, the brake
wa rning/ind icator light will illuminate. Contact an authorized Aud i
dealer
immediately .
[I] Tips
The brake fluid reservoir is located undernea th the cover. •
Changing brake fluid
Hove the broke fluid changed by on experienced techni­
Clon.
Brake fluid absorbs moisture from the air. If the water content in the
brake fl uid is too high, corrosion in the brake system may result after
a period of time. The boiling point of the brake fluid will also decrease
considerably and decrease braking performance.
Therefore, the brake flu id must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan­
dard "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 authorized
Audi dealer. Your dealer has the correct tools, the right brake fluid
and the know-how to do this for you .
& WARNING
• Brake fluid is poi sonous. It must be stored only in the closed
original container out of the reach of children!
Safety first
& WARNING (continued )
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions:
-Use only brake fluid that meets SAE specification
J 1703 and
conforms to Federal Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make sure you are using
the correct brake fluid . The correct type of brake fluid is also
indicated 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 .
0 Note
Brake fluid will damage the paint of your vehicle.
ffi For the sake of the environment
Because of the prob lem of proper disposal of brake fluid as well as
th e special tools required and the necessary expertise, we recom­
mend that you have the brake fluid changed by your author ized 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 leve l
should also be checked each t ime the battery is charged=> page 288.
~
Vehicle care Technical data

___ C_ h_ e_c _k _i _ n _g ~ a_n _d_ f_il _l_in _ g _________________________________________ _
Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle e lectrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 204.
Disconnecting the battery terminals
Some vehicle functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected aga in . To
prevent this, the battery should only be disconnected from the
vehicle electrical system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not dr ive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability over a
longer period=>
page 243.
Take into consideration that when you unlock you r vehicle, some
convenience functions, such as the master key remote function or
power seat adjustment, may not be available. The convenience func­
tions will be available again when you turn on the ign ition and start
the engine.
W inter operation
During the w inte r months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
wh ile starting, and the headlights, rear window defogger, etc., are
used more often.
Avoid unnecessary power consumption, particularly 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
=> page 288. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer.
W Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced .•
Working on the battery
Be especially careful when working on or near the
battery.
The battery is located in the luggage compartment under the
floor. Before you check anyth ing in the lu~gage compart­
ment,
read and heed all WARNINGS:=>& .
Always heed the safety warnings, when working on the vehicle
battery or the vehicle electrical system to prevent injury .
The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre­
cautions when working on the battery.
Always wear eye protection.
Battery acid contains sulfuric acid. Always wear
gloves and eye protection . .,,_

Ill Tires and wheels
-------------------
& WARNING (continued)
overheat and can lead to tire failure . Under-inflation also is likely
to impair the vehicle's handling and stopping ability.
• The driver is responsible for maintaining the correct tire pres·
sures. You must check the tire pressures regularly.
• Under certain conditions (such as a sporty driving style, winter
conditions or unpaved roads), the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run-flat tires may be used on
your vehicle. Your vehicle registration becomes invalid if you use
these tires when not permitted. Damage to your vehicle or acci­
dents could also result.
[ i J Tips
• The tire pressure monitoring system stops working when there is
an ESP/ABS malfunction.
• Using snow chains may resu lt in a system ma lfunction .
• To ensure a proper TPMS function use AUDI Original Tires which
are marked with "AO" or "RO" on the tire sidewall. =>
page 303.
• The tire pressure monitor ing system on your Audi was calibrated
using tires with the "AO" or "RO" identification. We recommend
using these tires.•
Applies to vehicles: with tir e pressure monitoring system
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are rotated or
changed, the TPMS must be reset via radio or MMI*.
-Turn on the ignition.
- Select: the [ CAR] function button
> Tire pressure
monitoring
> Store now.
W Tips
Before resetting the TPMS, the current pressures of all four t ires
must correspond to the specified values . Adjust the tire pressure and
reset the pressure in the tire pressure monitoring system according
to the load you are carrying=>
