Fa ults in the brake system
If yo u should notice a sudden increase i n brake
pedal travel, then one of the two brake circuits
may have failed
¢ .&. .
Low brake fluid level
Malf unct ions can occur in the bra ke system if the
b rake fl uid leve l is too low. The brake fluid level
i s monitored e lectronica lly .
Bra ke booste r
The brake booster increases the pressure that
you generate with the brake pedal.
It works on ly
when the engine is run ning
.¢ .&.
Bra ke lining we ar status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If necessary,
the wheel may be removed for this inspection
¢ page 228, Replacing wheels.
A WARNING
- New bra ke pads don't have the best stop­
ping power and must be "bro ken- in" dur ing
the init ia l 250 m iles (400 kilometers). Yo u
can compensate for th is by press ing the
brake pedal more firmly. This a lso applies
later when new pads are installed.
- Yo u should perfo rm braking maneuvers for
the p urpose of clean ing 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 t ransm iss ion into a lower
gear or lowe r driving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could ca use the brakes to get
hot and diminish brak ing efficie ncy.
- Do not "r ide t he b rakes" by resting your foot
on the pe dal when yo u do not inten d to
bra ke. This may cause the bra kes to over­
heat, premat ure wear and increased stop ­
ping distance.
- Under certa in climatic and operating condi­
tio ns such as passing thro ugh water, driving
in heavy rain or after washing the vehicle,
Intellig ent Technology
the effectiveness o f the brakes can be re­
duced. In winter, ice can accum ulate on the
brake pads, lin ings, d iscs and drums . Care­
fu lly apply brakes for a test . Brakes will dry
and ice coat ings will be cleaned off after a
few ca refu l brake applications .
- Driving for an extended period of t ime on
salt-covered roads without usi ng your
b rakes can also affect braking eff iciency.
Clea n off acc umul ated salt coat ing from
b rake discs an d pa ds w ith a few careful
b rake appli cat ions .
- I f you d amage the front spoile r, or if you in­
s t all a different spoiler, be s ure the a ir flow
to the front brakes is not obstruc ted. Other­
wise the brake system could overheat reduc­ ing the effectiveness of t he ent ire bra ke sys­
tem.
- Fai lure of one brake circuit w ill impa ir the
braking capability resulting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest authorized
Aud i dealer or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed cons iderab ly
ha rder to make up fo r the lack of booste r
assis tance .
Electro-mechanical
power assist, dynamic
steering
The electro-mechanical power assist helps the
driver when steering.
Power steer ing adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defe ctive! Do not drive vehicle!
If this indicato r light turns on and stays on and
t hi s message appears, the powe r steering may
have failed.

Trailer towing 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, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle 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 with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bo lts remain securely fastened.
When you are not towing a trailer,
remove the
tra iler hitch ball mount . This prevents the hitch
from causing damage shou ld your vehicle be
struck from beh ind ¢
,&. .
Trailer brakes

Trailer towing
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢.&. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
T ra iler lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor­
rect wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision to the rear.
,8. WARNING
-If a tra iler has electr ical brakes please note
that these bra kes are not activated by the
factory-fitted control unit -risk of accident!
- After removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held sec ure ly in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 180.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure that
the cool ing system has enough fluid. .,..
179

Trailer towing
Tire pr essure
When tow ing a tra iler, inflate the tires of yo ur
veh icle to the tire pressure listed under " Fu ll
load" on the label ¢
page 217. Inflate trai ler
tires to trai ler and tire manufacturers' specifica­
tions.
Lights
The headlight settings should be chec ked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be s ure t railer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle .
L eave enough slack in the chains to permit turn ­
ing corners. When you install safety chains, make
sure they wi ll not drag on the road when you are
driving.
The chains shou ld 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 .
Weight distribution
Towing a loaded trailer with an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avo ided, drive at very low speeds on ly
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and cont rol.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while keeping the trai ler as light as possib le under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observ ing tongue load requ ire­
ments and vehicle loading considerat ions .
Spe ed
The higher the speed, the more difficult it be­
comes for the driver to contro l the rig. Do not
drive at the maximum permiss ible speed. Reduce
your speed even more if load, weather or w ind
180
conditions are unfavorab le -particularly when
going downhi ll.
Reduce vehicle speed
immediate ly if the trailer
shows the slightest sign of sway ing.
Do not try
to st op the swaying by accele rating.
Observe speed limits. In some a reas, speeds fo r
vehicles towing tra ilers are lower tha n for regular
vehicles.
A lways apply brakes ear ly . When driving down­
hill, shift into a lower gea r to use the engine
braki ng effect to slow the vehicle. Use of the
brakes alone ca n cause them to overheat and fa il.
Coolant temperature
The coolant temperature gauge¢ page 8 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­
med iate ly and/or tu rn off the a ir cond itioner .
If the coolant temperatu re warning light . in
the instrument cluster starts flashing, p ull off
the road, stop and let the engine
idle for about
two minu tes to p revent heat build-up .
.&, WARNING
Anyone not properly res trained in a moving
vehicle is at a much greater risk in an acci ­
dent . Never let anyone ride in your car who is
not properly wear ing the restraints provided
by Aud i.
Trailer towing
information
Important to know
-
Your vehicle handles differently when towing a
trailer because of the addit iona l weight and dif­
ferent weight distribution. Safety, performance
and economy will greatly depend on how careful­
ly you load your tra iler and operate your rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic. Keep pract icing u nti l you have be­
come completely fam iliar w ith the way your vehi-
cle-tra ile r combination behaves and respo nds . .,.

engi ne oil from Au di Genuin e Parts
Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a h igh-quality oil
which can usually be used throughout the entire
yea r.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty & Maintenance booklet .
- Use only a high qual ity eng ine oil that ex-
pressly complies with the Audi oil quality
standard specified for your vehicle's engine .
Using any other oil can cause serious engine
damage.
- Do not mix any lubricants or other additives into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa ­
ble that meets the Audi oil quality standard
your engine requires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality
"synthet ic"oil that meets the following speci­
fications.
- Vehicles w ith gasoline eng ine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W-30 or SAE 5W-40.

· Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lubricat ion and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption var ies from engine to en­
gine and may change sign ificantly over the life of
the engine . T ypically, engines w ith a specified
break -in period (see¢
page 175) consume more
oi l during the break-in period than they consume
after oil consumption has stabilized.
U nder normal cond itions, the rate of oil con­
sumption depends on the quality and viscosity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions. Further factors are
the amount of o il dilution from water condensa­
tion or fuel residue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the o il consumption may increase over
ti me unt il replacement of wo rn compo nents may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and freq uent checki ng of the oi l level, see
Note.
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up, you sho uld
chec k the o il level as soon as possible

A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS

@ 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
¢ page 205.
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.
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 disco nnected 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 period¢
page 173.
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.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . T his is be-
Checking and Filling
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 traff ic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in ¢
page 205. 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 luggage compart­
ment under the floo r. Before you check anything
in the luggage compartment,
read and heed all
WARNINGS ¢
LD.·
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
