16 Instruments and warning/indicator lights
CRUISE/ vJ' Cruise control
The iR;\l)~i~ (USA models)! II (Canada models)
warn ing/ indicator light illum inates when the
cruise control is act ivated .
~/ !.!r Safety systems
The I (USA models)/ . (Canada mode ls) in ­
dicator light monitors the safety systems e.g.
airbags, pretensioners and illuminates for a
few seconds each time you switch the ignition
on .
If the
I (USA models)/ . (Canada models)
indicator light does not go out, or if it illumi­
nates while you are driving, or if it starts to
blink, then there is a malfunction somewhere
in the system . If the light does not illuminate
when you switch on the ignition, this also
means there is a ma lfunction.
_& WARNING
If you have a malfunction in the safety sys­
tems, contact your authorized Audi dealer
immediately. Otherwise the safety sys­
tems may not work properly in an acci­
dent.
0 Generator
This warning/indicator light detects a mal ­
function in the generator or in the vehicle's
electrical system.
The . warning/indicator light illuminates
when you switch on the ignition and must go
out after the engine has started .
If the . warning/ind icator light illuminates
while you are driving, you should contact your
authorized Audi dealer . Since the vehicle bat ­
tery is discharging, yo u should switch
off any
unnecessary electrical consumers (for exam­
p le, the air conditioner).
0 Note
If the . warn ing/indicator light (mal­
function in the engine cooling system) in
the instrument cluster should illum inate
¢ page 31, stop the veh icle and turn off
the engine. The coolant pump is not work­
in g -this can cause engine damage!

BRAKE/ ((D ) Brake system
This warning/indicator light illuminates when
the brake fluid level is too low or when there
is a malfunction in the ABS, or when the park­
ing broke is set.
T he light 1111 (USA)/ . (Canada) ill umi­
nates when the igni tion is turned on.
It goes
out after the engine has been started and the
parking brake is fully released. This indicates
that the brake warning light is functioning
proper ly.
If the brake warning light does not light up
when the engine is cranking or the parking
brake is applied, there may be a malfunction
in the electrical system. In this case , contact
your Audi dealer.
If the ABS fails, the ABS warning/indicator

A WARNING
Driv ing at higher speeds w ithout the rear
spoiler dep loyed can impair handling char­
acteristics, making the vehicle harder to
control.
- Always make sure that the spoiler is de·
ployed whe n driving at speeds over 85
mp h (140 km/h) . If the rea r spo ile r
wa rning/ind icator light in the instru­
ment cluster comes on, the rear spo iler
may not have dep loyed.

Braking
General information
What affects braking efficiency?
Ope rating condition s and driving h abits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits ¢.&, . On ve ­
hicles that a re either dr iven mostly in stop­
and-go city t raff ic or are dr iven hard, the
brake pads should be chec ked by yo ur author­
ized Audi dea ler mo re often than specified in
the
W arranty & Maintenanc e boo klet. Failure
to have your brake pads inspected can result in reduced brake performance .
On steep slopes, you should use the braking
effect o f the engine . This way, you prevent un ­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont in uous ly. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
the speed, braking force and o utside condi­
tions such as temperature and humid ity.
Moisture o r ro ad s alt
U nder certa in conditions, for examp le, when
driving through water or very heavy rain , or
even after washing your vehicle, the b raking
effect can be reduced due to moist ure (or in
freezing cond itions ice) on the brake pads. A
few cautious brake applications should dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and t he brakes are not used. L ikewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap-
plications of the b rake ¢ .&, .

152 Intelligent technology
Corrosion
There may be a tendency fo r dirt to bu ild up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes .
I f the b rakes are not used frequen tly, or if cor ­
rosion has fo rmed on the discs, it is advisab le
to clean
off the pads and discs by b raking
firm ly a few times from a moderate ly high
speed
c> .& .
Fault s in the bra ke sy ste m
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circu its may have failed¢.& .
Low brake fluid level
Malf unc tions can occur in the brake system if
the brake fl uid level is too low. The b rake fluid
l eve l is monitored electronica lly .
Brake lining wear status
Brake lin ing wea r may be c hecked by visual i n­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the whee l may be removed for this in­
spection ¢
page 222, What should I be
aware of when changing a tire?.
Brake power assist unit
The brake power assist un it increases the
p ress ure th at yo u genera te with the b rake
pedal. It works on ly when the engine is run­
ning.
& WARNING
- Yo u should perform braking maneuve rs
for the purpose of clean ing the brake
system on ly if road condit ions permit.
Other road users must not be put at r isk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss io n into a lowe r
gear or lowe r driving position . Do not
ride the brak es or ho ld the pedal down
too long or too ofte n. This cou ld cause the brakes to get hot and dimin
ish b rak­
ing efficiency.
- Do not " ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain cl imatic and ope rat ing
conditions such as passing through wa­
ter, dr iv ing in heavy rain or after washing
the vehicle, the effectiveness of the
b rakes can be reduced . In wi nte r, ice can
a ccumu late on the br ake pads , lin ings,
d iscs and drums. Cautiously app ly bra kes
for a test . Brakes wi ll dry and ice coat ­
ings wi ll be cleaned
off after a few cau­
tious b rake app lications .
- Driving for an exten ded period of t ime on
salt-covered roads without using your
brakes can a lso affect bra king efficiency.
Clean
off accum ulated salt coating from
brake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you
install a diffe rent spoiler, be sure the a ir
f low to the front b rakes is not obs truc t­
ed. Otherwise the bra ke system could
overhea t redu cing t he effectiveness o f
the entire brake system.
- Fai lure of one b rake circuit will impa ir
the braking capa bility result ing in an in­
cre ase d stopping dist ance. Avoid driving
the vehicle and have it towed to the near ­
est A udi dealer or qualified workshop .
- Never let the vehi cle roll to a s top with
the engine sh ut
off .
- If t he bra ke booste r is no t working, for
examp le when towing yo ur vehicle, or
because the brake booster has somehow
been damaged, the bra ke peda l must be
pressed considerably harder to make up
for the lack of booster assistance .

Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the fir st 600 mile s (1,000
kilometre s):
.,. Do not use full throttle .
.,. Do not drive at engine speeds that are more
than 2/3 of the max imimum permitted
RPM .
.,. Avoid high engine speeds.
From 600 to 1,000 miles (1 ,000 to
1,500 kilometres):
.. Speeds can gradually be increased to the
maximum pe rm iss ib le road or eng ine speed .
During and after break-in period
.. Do not rev the engine up to high speeds
when it is cold . T hi s applies whether the
transmission is in N (Neutral) o r in gear.
After the break- in period
.. Do not exceed max imum eng ine speed un­
der any circumstances .
.. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
<::;> page 10.
During the first few hours of driving, the en­
g ine's inter na l friction is higher tha n later
when all the moving pa rts have been broken
i n. How well this break-in p rocess is done de­
pends to a considerable exten t on the way t he
veh icle is driven d uring the first 1,000 miles
(1, 500 kilome tres) .
(D Note
Extremely high engine speeds a re auto­
mat ic al ly reduced. However, t hese RPM-
Driving and environment 157
limits were programmed for an eng ine
well run-in, not a new eng ine.
@ For the sake of the environment
Do not d rive wi th unnecess arily h igh en­
gine speeds -upshifting ear ly saves f uel,
r educes noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly carefu l for the first 350 miles
(500 ki lometres) after fitting .
A WARNING
-New tires tend to be s lippery and must a l-
so be "b roken-in". Be s ure to remembe r
this dur ing t he firs t 35 0 m iles (500 kilo­
me tres) . Brake gent ly . Avo id following
closely behind other vehicles or other sit­ uations that m ight require sudden, hard
b raking.
New brake pads
Remember that new brake pads do not have a
full brak ing effect during the first 250 m iles
(400 kilometres) after they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&..
D uring the break-in period, yo u should avoid
putting seve re loads on the brakes . Severe
l oads include, for example, su dden hard brak­
ing, in particular at very h igh speeds or, for
example, on mou nta in passes.
A WARNING
Until t hey develop the maximum "bite" for
best stopping power, the s urfaces on new
b rake pads requ ire some "brea king- in" dur­
in g the initial 10 0 to 150 miles (15 0 to
20 0 kilome tres) of normal c ity dr iv ing. Yo u
can compensate for this by press ing the
b rake peda l more f irm ly . This applies
whenever new pads are installed.

158 Driving and en vi ro nm ent
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehicle body.
- Do not d rive faster than wa lking speed.
_& WARNING
After d riving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv ­
ing through it.
- Do not stop the veh icle, drive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.
-
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
.. Always use lead-free gasoline ¢ page 17 4,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much motor o il in your eng ine
r::;> page 183, Adding engine oil~-
.. Never try to p ush- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean­
up" dev ice built into the exhaust system of
t h e vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be ­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert­
er and prope r funct ion ing of the engine.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converter .
- Do not exceed the correct engine oil level
¢page 183.
-Do not drive until the fuel tank becomes
completely empty . The engine could mis-
fire. Unburned fuel could also get into ..,.

-To avoid being burned, do not sp ill an­
tifreeze or coolant on the exhaust sys­ tem or hot engine parts. Under certa in
conditions, the ethylene glyco l in en­
g ine coolant can catc h fire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its or iginal co ntaine r and well
o ut of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly ma rked "poison".
(D Note
- Coolant pollutes the env ironment and
could cause a n engine fire. Excess cool­
ant wi ll be forced out through the pres­
su re re lief va lve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the cor rect ratio be tw een wate r
and antifreeze
¢page 185 must be re­
store d as soon as possib le.
@ For the sake of the environment
Drained coolant s hould no t be reused. Al­
ways dispose of use d coolan t w hile obse rv ­
ing all envir onmental reg ulations.
