Instead, contact you r authorized Audi
dealer fo r assis tance.
[ i ] Tips
• The engine oil pressure symbol 'I=:?: is not an indic ato r for a low
engine oil level. Do not rely on it . Instead , check the oil level in your
engine at regular intervals , preferably each t ime you refuel, and
always before going on a long tr ip .
• The yellow oil level warning indication requires oil refill or
workshop service without de lay . Do not wait until the red oil pre s­
s ure warning symbol~ starts to flash before you respond to the
low oil level warning _, . By then, your engine may already have
s uffered serious damage. •

'-----------------------------------------------
& WA RNING (conti nu ed )
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
pa ssing through water, dr iving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter ,
ice can accumulate on the brake pads , linings , discs and drums .
Carefully apply brakes for a te st. Brakes will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can al so affect br aking efficiency. Clean
off accumulated salt coating from brake disc s and pads with a few
careful brake applic ations.
• If you damage the front spoiler , or if you in stall a different
spoile r, be sure the air flow to the front brakes is not obstructed.
Otherwi se th e brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an inc reased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop .
.J
Brake booster
T h e brake booste r adds ext ra braking p ower.
The brake booster works with vacuum pressure which is created on ly
w hen the eng ine is ru nnin g=>&.
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake boo ster i s not working , for example when towing
your veh icle , or because the brake booster has somehow been
& W ARNING (continued )
damaged , the brake pedal must be p ressed considerably harder to
make up for the la ck of booster assi stan ce. •
Functioning of Anti-Lock Brake System
{ABS)
ABS prevents the wheels from l ockin g up under br aking.
Th e ABS contr ibutes effectively to vehicle co ntrol s ince it prevents t he
w heels from
locking when the brakes are applied . This means that the
veh icle rema ins steerable and is less likely to skid .
With ABS you do not need to pump the brake. Just hold the brake
pedal down .
However, do no t expect that the ABS shortens bra king d istance under
all circumstances . When dr iv ing on grave l or on newly falle n snow on
top of icy s urfaces, braking d istance may be even longer, therefo re,
under these circumstances, it is especially important that yo u drive
slowly and with g re at c are.
How the ABS system works
An au tomatic c hec k is made when a speed of about 4 mp h (6 km/ h) is
reached. When t his happens, a pump ing noise can be heard.
If an ind ivi dual wheel begi ns to rot ate too s low ly in relat ion to ve hicle
speed and tends to loc k, t he ABS automatically reduces brake pres­
s ur e to p revent t hat wheel from lo cking.
T hi s au tomatic adjustment p rocess w ill cause a
s light vibration of
the bra ke pedal and some noises to a lert you that vehicle speed must
be adapted to ex isting road and traffic co nditions .
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving ...

Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and-go traff ic conditions, or when you use your vehicle where temper­
atures stay below freezing point for long periods .
Detergent additives in the oil will make fresh oil look dark after the
engine has been run ning for a short time . This is normal and is not a
reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essentia l that you change your oi l at the recommended intervals
using only engine oil that complies with Audi oi l standard VW 502 00
(vehicles with gasoline engine) or VW 507 00 (vehicles with diesel
engine). 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 Manua l and
Warranty
& Maintenance booklet. Your dealer will have to deny
warranty coverage unless you present to the dealer proof in the form
of Service or Repair Orders that all scheduled maintenance was
performed in a timely manner .•
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumpt ion varies from engine to engine
and may change significant ly over the life of the eng ine. Typically,
engines with a specified break- in period (see~
page 197) consume
more oi l during the break-in period than they cons ume after oil
consumption has stabilized.
Under normal cond itions, the rate of oil consumpt ion depends on the
quality and vis cosity of the oil, the RPM (revol utions pe r minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oi l dilution from water condensation or fuel residue and the ox
idation level of the o il. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil level warning symbol in the instrument
cl uster .... lights up, you should check the oil level as soon as possible
with the oil dipstick~ page 231. Top off the o il at your earliest
convenience ~
page 232.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Work ing in the engine
compartment" on
page 226.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine .
[ i ] Tips
• The oil pressure warning display 't::r. is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and alway s
before going on a long trip.
• If you have the impression your eng ine consumes excessive
amounts of oi l, we recommend that you consu lt your authorized Audi
dea ler to have the cause of your concern properly diagnosed. Keep in
mind that the accurate measurement of oil consumption requires
great care and may take some time . Your authorized Audi dea le r has
instructions about how to measure oil consumption accurately. •

level sensor, we still recommend you check the coolant leve l from
ti me to time.
Coolant loss
Coolan t loss may ind ic a te a leak in the coo ling sys tem. In the event of
coo lant loss, the cooli ng system should be inspected immed iately by
your au thor ized A udi dealer.
It is no t enough merely to add coolan t.
In a
s ealed system, losses can occur only if the boiling point of the
coo lant is exceeded as a res ult of overheating .
(D Note
Do not add any type of radiator leak sealant to yo ur vehicle's engine
c oo lant. Addi ng radia tor repa ir fluid m ay adverse ly affect the fun c­
tion and perfo rmance of your cooling system and could result in
damage not cove red by yo ur New Vehi cle Lim ited Warranty .•
Adding coolant
B e very careful when adding engine coolant.
Before you check anyt hing in the eng ine compartment ,
always read and heed all WARNINGS=> & in " Working i n
the e ngine compartment" on page
226.
-Tur n off the eng ine.
- Let t he engi ne c ool d ow n.
- Place a thick rag over the coolant expansion tank
=> pa ge 235, fig . 166 and carefully twist t he cap cou nte r­
clockwis e
=> &.
- Add coo lant.
- Tw ist the ca p on aga in
tightly .
Replacement eng ine coolant must conform to exact spec ificat ions
=> page 234, " Coolant" . Even in a n emergency, if coolant additive
Gl2 ++. Gl2+ or Gl2 is not available , do not use a d ifferent addit ive .
Use pla in w ate r ins tead until you can ge t the cor rect addi tive and can
restore the co rrect ratio . This sho uld be done as soon as possib le .
If you have lost a considerable amount of coolant, then you s houl d
ad d c old antifree ze and cold water only when the engine is cold .
Always use
new engine coo la nt w hen refilling .
Do not fill coolant above the "M AX" mark. Excess coo lant will be
forced out th rough the p ress ure relief va lve in the cap w hen the
eng ine becomes hot.
& 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 engine and allow it to cool down.
- Protect your face , hands and arms from escaping 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.
- To avoid being burned, do not spill antifreeze or coolant on
the exhaust system or hot engine parts . Under certain condi­
tions, the ethylen e gly col in engine coolant can catch fire .
• Antifreeze i s poi sonou s. Always store antifreeze in it s original
container and well out of the reach of children.
• If you drain the coolant , it mu st be caught and safely stored in
a p roper container clearly marked "poison ".
(D Note
• Coolant pollutes the environment and could cause an engine fire.
E xcess coolant w ill be forced o ut thro ugh the pressure relie f va lve in
the cap when the e ngine becomes hot .

Wheel bolts
Wheel bolts must al ways be tight ened to the c orrect
torqu e.
The desig n of whee l bolts is matc he d to the fa ct ory in stalled rims. If
different r ims are fitted, the cor rect wheel bo lts wi th t he r igh t length
and correctly s haped bolt hea ds must be used . Thi s ensures that
Safety first
wheels are fitted securely and that the brake system funct ions
cor rectly .
I n certa in circumstances, yo u may not use wheel bo lts from a
different vehicle -even if it is the same mo del.
& WARNING
Improperly tightened or maintained wheel bolts can be come
loose causing loss of control, a collision and serious personal
injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolt s can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the th reads in the wheel
hub s. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolt s that belong to the rim being installed .
• Never use different wheels bolts on your vehicle .
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low, they can loo sen and come out when the
vehicle is moving . If the tightening torque is too high , the wheel
bolt s and thread s can be damaged and the wheel can become
loose.
