Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first¢.&. . You can com­
pensate for this slightly reduced braking power
by push ing harder on the brake pedal. Avoid
h eavy braking loads during the break-in period .
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear , depend ing largely on operating con­
d itions and dr iving habits ¢.&. . On veh icles that
are e ither dr iven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi deale r more of­
ten than specified in the
Warranty & Mainte­
nance booklet.
F ailure to have your brake pads inspected can result
in reduced brake perform­
ance.
On steep slopes, you should use the braking ef­
fect of the engine. This way, you prevent un nec­
essa ry wea r on the brake system. If you must use
you r brakes, do not hold the brakes down contin­
u ous ly. Pump the brakes at intervals.
Operating noise
Noises may occur when braking depending on the
speed, bra king fo rce and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overn ight con­
densation or afte r wash ing your car, the brak ing
effect can be reduced by moisture or ic e on the
brake rotors and brake pads. The brakes must be
dried f irst with a few careful brake applications .
At h igher speeds and w ith the windshield wipers
turned on, the brake pads press against the brak e
rotors for a short amount of time. This occurs at
regular intervals without the driver noticing and
provides for better brake response t ime under
wet conditions.
T he effectiveness of the brakes can be reduced
when the vehicle is driven on a sa lt-covered road
and the brakes are not used . Likewise, yo u clean
off accum ulated salt coating from brake discs
and pads with a few cautious applications of the
brake¢ .&..
Corrosion
There may be a tendency fo r dirt to build up on
the brake pads and corrosion to form on the discs .,..

Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
~ Shut the engine off when you are not driving
the vehicle.
~ Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automat ically reduced for
veh icles w ith the Start-Stop-System. It is effi­
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at ra ilroad
crossings and long red lights . Turning the engine
off for just 30-40 seconds saves more fuel than is
b ur ned by sta rting the engine ag ain.
It takes a long t ime for the engine to warm up
fu lly when it is runni ng at idle . Howeve r, wear
and noxio us emiss ions a re espe cially high when
the eng ine is wa rm ing up. So you sho uld d rive
away as soon as you sta rt the engi ne and avoid
r u nning at high rpms whi le the engine is still
warming up .
(D Note
Do not leave engine id ling unatten ded a fter
starting . If warning lights should come on to
indicate im proper operation, they wou ld go
unheeded. Extended id ling a lso produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other proper­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
~ Have your veh icle serviced at regu lar intervals.
By having your veh icle reg ularly serviced by an
Audi dea ler helps to ensure that it runs proper ly
and econom ica lly. The condition of your veh icle
not on ly affects its safety and ability to ho ld its
va lue, it a lso affects
fuel consumption .
Check you r oil each time you fill your tank.
The amount of oil use d i s re lated to e ngine lo ad
a nd speed.
Driving and the envir onment
It is normal for the oil consumption of a new e n­
gine to reach its lowest value after a certain mi le­
age has been dr iven.
Yo u m ust dr ive your ve hicl e abou t 3,0 00 m iles
(S, 000 kilometers) befo re yo u can properly as ­
sess oil consumption .
T h is also ap plies to f ue l cons umption and eng ine
o utput .
CD Note
-Have your ve hicle maintained pro perly and
in acc ordance w ith the se rvice rec ommend a­
ti ons i n your W arra nty
& M ain ten ance book­
let . Lack of proper maintenan ce as we ll as
improper use of the ve hicl e w ill impair the
function of the em ission cont rol system and
co uld lead to damage.
- Do not alte r or remove any component of
the Emission Contro l System unless ap­
proved by the man ufacturer.
- Do not alte r or remove any device, such as
heat shields, switches, ign it ion w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System a nd othe r
im por tan t ve hicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~ Try to avo id driv ing short distances with a cold
eng ine .
T he engine and cata lytic conve rter have to reach
their opt imal
operating temperature to reduce
fuel consumpt io n and noxious emiss ions effec­
tively.
Just afte r starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 m iles per
gallo n (30-40 l/ 100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . Afte r about
2 .5 m iles (4 km), the eng ine is
at its p roper operat ing temperature and fue l
eco nomy has reached a no rma l level. So yo u can
see th at yo u should avoid short trips w heneve r
poss ible. .,.

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, econo­
my and performance.
T railer tow ing not only p laces more stress on the
vehicle, it a lso calls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trailer, you must ac­
tivate the trai ler operation mode
¢ page 199, Operating instructions.
Technical requirements
Tr ailer hitch
Use a weight -carrying hitch conforming to the
gross tra iler weight. The h itch must be suitab le
for your vehicle and tra ile r and must be mo unted
securely on the vehicle's chassis at a
technically
sound
location . Use on ly a trailer hitch with a re­
movable ba ll mou nt. Always che ck wit h the t rail­
e r hitch manufac turer to make s ure that you a re
usi ng the co rrect 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 mod ifica tions should be
made to the vehicle exhaust and brake systems .
Fr om time to time, chec k that all hitch mo un ting
bo lts rem ain securely fastened.
W hen you are not tow ing a trailer,
remove the
tra iler hitch ba ll mount . This prevents the hitch
from ca u sing damage s hou ld your veh icle be
struck from behind
¢ .&, .
Trailer mode
Trailer brakes
If your traile r i s equ ipped with a b raking sys tem,
c h ec k t o be sure that it con forms to a ll regu la ­
tions.
T he tra ile r h ydr aulic bra ke sy stem must not be
directly con nected to the vehicle's hydr aulic
brake sy stem.
Safety chains
Always use safety chains between your vehicle
and the tra iler .
Trailer lights
Trailer lights must meet all regulations. Be sure
to check w it h your Aud i dealer for correct wir ing,
swi tches and relays .
Mirrors
If you are unab le 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 .
A WARNING
--
After remov ing the tra ile r hi tch, do not sto re
i t in yo ur vehicle. In case of sudde n brak ing,
t he hitch could fly fo rwa rd and injure you or
your passengers.
Operating instructions
Maximum trailer weight
A traile r for yo ur vehicle is lim ited to a typical
cla ss 1 or class 2 trailer.
Trailer load distribut ion
Be sure the load in the tra iler is held secure ly in
place to p reve nt it from shifting forward, back­
ward o r sideways.
Ne ver allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 201 .
Engine cooling system
Towing a tra ile r makes the engine wor k 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 enoug h fluid . .,..

Trailer mod e
Tire pr essure
When tow ing a tra iler, inflate the tires of you r
veh icle to the cold tire pressure listed under "Fu ll
load" on the label located on the driver's side B ­
pillar (visib le when the door is open) . Inflate
trai ler tires to trailer and tire manufacturers'
specifications.
Light s
Check to make sure both vehicle and trailer lights
are working proper ly.
Safet y chains
Be sure t railer safety chains are properly connect­
ed from the trailer to the h itch on the veh icle.
L eave enough slack in the chains to permit turn­
ing corners . When yo u 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 .
Adjusting the Audi d rive select
Make sure the vehicle is on a level surface bef ore
hitching up the t railer and bef ore adjust ing the

· Driving instructions
Driving with a trailer always requires extra care
and consideration .
To obtain the best possible hand ling of veh icle
and trailer, please note the following:
.,. Do not tow a loaded trailer when your car itself
is not loaded .
.,. Be especially careful when passing other
vehicles .
.,. Observe speed limits .
.,. Do not dr ive at the maximum permissible
speed.
.,. Always app ly brakes ea rly.
.,. Monitor the temperat ure gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
i n a h ighly unstab le distribution of weight . If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steer ing contro l.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
k eeping the trailer as l ight as poss ible under the
c ircu mstances . Wheneve r possib le, transfer
some ca rgo to the luggage compartment of the
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the mo re diff icu lt i t be ­
comes fo r the driver to con trol the r ig . Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
cond itions are unfavorab le -particularly when
go ing downh ill.
Reduce vehicle speed
i mmed iatel y if the trailer
shows the slightest sign of swaying.
Do not tr y
to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds for
vehicles towing trailers are lower than for regular
vehicles .
Always apply bra kes early. Whe n driving down -
hill, shift into a lower gear to use the engine .,..

Using the prope r engine oil is important for the
functiona lity and service life of the eng ine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year.
@ 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 quality eng ine oil that ex-
pressly complies with the Aud i 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.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality

.... M Ch eck ing and Filling
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports.
In order to provide effect ive lubrication and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption varies from eng ine to en­
gine and may change s ign ificantly ove r the life of
the engine. Typ ica lly, engines w ith a specified
break-in period (see
¢ page 194) consume more
oi l during the break -in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscosity o f
the oil, the RPM (revol utions per minute) at
which the engine is operated, the ambient tem­
perature and road condit ions. Further factors are
the amount of oil 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 oil consumption may increase over
time unt il replacement of worn components 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 frequent checking of the oi l level , see
Note .
If the yellow engine o il leve l warning symbo l in

• Park your vehicle on a level surface.
• Switch
off the ignition.
• Read the engine coolant level from the coolant
expansion tank¢
fig. 189, ¢ page 218,
fig. 186.
With a cold engine, the coolant level
should be between the "min" and "max" mark­
i ngs . When the engine is warm, the level may
be s light ly above the "max " marking.
The location of the coolant expans ion tank can be
seen in the engine compartment illustrat ion
¢pag e 218.
To obtain an accurate reading, the engine must
be sw itched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System
c:> page 15 wi ll il­
luminate until you add coolant and the level has
been restored to normal. Even though there is an
e lectric coolant level sensor, we still recommend
you check the coolant level from t ime to t ime.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
In a
sealed system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheat ing.
A WARNING
The cooling system is under pressure and can
get very hot . Reduce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and allow it to cool
down.
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of the
cap.
Checking and Filling
-To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certain cond itions,
the ethylene glycol in engi ne coolant can
catch fire.
(D Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Add ing radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢.&. in Working in the engine compartment on
page 216.
• Requ irement: There must be a residual amount
of coolant in the expansion tank

Replacement engine coolant must conform to ex ­
act specifications
c> page 222, Coolant.
We recommend using only coolant additive Gl2+
+ , Gl3
or in an emergency Gl2+. Do not use a
different additive. In an emergency use plain wa­
ter until you can get the correct additive and can
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of coo l­
ant, then you should add cold antifreeze and cold
water only when the engine is co ld.
Always use
new engine coolant when refi lling.
223

Check ing and F illing
Do not fill coolant above the "MAX" mark. Excess
coo lant wi ll be forced out through the pressure
relief valve in the cap when the eng ine becomes
hot.
A WARNING
- The cooling system is under pressure and
can get very hot . Reduce the risk of scald ing
from hot coolant by followi ng these steps.
- Tu rn off the engine and allow it to coo l
down.
- P rotect your face, h ands and arms from
escaping f lu id and steam by cover ing the
cap with a large, thick rag.
- Tu rn the cap slowly and very carefully in a
co unter -clockw ise direction while applying
light, downward p ressure on the top of
the cap.
- To avoid being bu rned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in condi­
tions, the ethylene glycol in eng ine cool­
a nt can catch fire.
- Antifreeze is poisonous. A lways store anti­
freeze in its original container and well out
of the reach of children .
- If you dra in the coolant, it must be ca ught
and sa fely stored in a proper conta iner
clearly mar ked "poison".
(D Note
- Do not add coolant if the expansion tank is
empty . A ir cou ld enter the cooling system

Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 216.
.,. Read the brake fluid level from the brake fluid
reservoir
¢fig. 190, ¢page 218, fig. 186. The
brake fluid level must be between the "MIN "
and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
¢page 218.
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
1111 (U.S. models) ;II (Canadian models)
will come on¢
page 14. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected. If the brake fluid level is too
low, the brake warning/indicator light will illumi ­
nate. Contact an authorized Audi dealer
immedi­
ately.
Checking and Filling
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 point of the brake fluid
will also 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 Federal 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 authorized
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 failure can result from old or inappro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
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 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.
