& WARNING
•
You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road users must not be put at risk -you may cause an accident!
• Before descending a steep grade, reduce speed and shift trans ­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often. This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake. This may cause the brakes to overheat,
premature wear and increased stopping di stan ce.
• Under certain climatic and operating conditions such as
passing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brakes can be reduced. In winter,
ice can accumulate on the brake pads , linings, discs and drums .
Carefully apply brakes for a test . 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 also affect braking efficiency. Clean
off accumulated salt coating from brake discs and pads with a few
careful brake applications.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes is not obstructed.
Otherwise the 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 increased stopping di stance . Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop .•

Driving and environment
------------------------------------------------'
- Lack of proper maintena nce as well as improper use of the
vehicle w ill imp air t he funct io n of t he emission con trol system and
could lead to damage.
<£> For the sake of the environment
Even when the Emiss ion Contro l System is operating properly, the
exhaust gas can have a sulfur-like exhaust gas sme ll under some
operat ing states. This depends on the s ulfur content of the fue l being
used. Using a differe nt brand of fuel may help, or filling the tank with
lead-free supe r grade gasoline. •
Avoid damaging the vehicle
When you are dr iving on poor roads, or ove r cur bs, steep r amps, etc.,
make certain that low-lying parts such as spoilers and exhaust system
p arts do not bo ttom ou t and ge t damage d.
Th is is espec ia lly true for vehicles with low-slung chass is (sports
chassis)* and fully loaded vehicles .•
Driving through water on roads
N ote the following to avoid vehicle damage w hen driving through
water, fo r examp le on flooded roads:
• The water must not be any higher than the bottom of the vehicle
b ody.
• Do not drive faster tha n walking speed.
& WARNING
After driving through water , mud, slush , etc. , the brakes may be
slow to take effect because of wet brake rotors and pads . Dry the
brakes first by braking carefully to restore the full braking effect.

Engine oil consumption
Th e e ngin e in your v ehi cle dep ends on an ad equate
amount of oil to lubricate and cool a ll of its movin g parts.
In order to p rovide e ffect ive lubric ation and cooling of inter na l
eng ine components, all internal combust ion eng ines consume a
c ert ain a mo unt o f oil. Oil co nsump tion va ries from e ngine to eng ine
and may change sign ifican tly over the li fe of the engine . Typically,
eng ines w ith a sp ecifie d brea k-in period (s ee =>
page 261) co nsum e
more o il dur ing the break -in period t han they cons ume a fter oil
cons umption has stabilize d.
Under norm al cond itions, th e ra t e of oil con su mp tio n depe nds on t he
quality and v iscosi ty of the oil, the RPM ( revolutions pe r minute) at
w hich the engi ne i s op erate d, the ambie nt te m pe ratu re and r oad
conditions. Further factors are the amount of oi l di lution from water
co ndens ation or f uel re sidue and th e oxid ation level of the oil. As any
eng ine is s ubject to wear as mileage builds up, the oil consumption
may increase over time until replacemen t of wo rn components may
become necessa ry .
With all these varia bles comin g into play, no stan dar d rate of oil
co nsum ption can be establis hed o r spe cified. Th ere is no alte rnative
to regular and frequent chec kin g of the o il level, see
Note .
If the yellow e ngine oil leve l w arning symbol in the ins trumen t

[ i ] Tips
• The oil pressure warn ing display 'e.::1; 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 always
before going on a long trip .
• If you have the impression your eng ine consumes excessive
am ounts of o il, we recom mend that you cons ult your Audi dea le r to
have the cause of your concern properly d iagnosed. Keep i n m ind that

- Top off the oil again, if necessary.
- Screw the cap back on the filling hole and slide the oil
dipstick in as far as it will go.
& WARNING
• While topping off, the oil must not come in contact with hot
engine parts - fire hazard!
• The oil filler cap must be properly secured to prevent oil from
being sprayed on the hot engine and exhaust system when the
engine is running - fire hazard!
• If your skin has come in contact with the engine oil, you must
subsequently cleanse it thoroughly.

Safety first
<£' For the sake of the environment
• Under no circumstances can the oil come in contact with the
sewage network or the soil.
• Observe and follow legal regulations when disposing of empty oil
containers. •
Changing the engine oil
We recommend that have your oil changed by an autho­
rized Audi dealer or a qualified service station.
Before you check anything in the engine compartment, always read
and heed all WARNINGS=>
& in "Working in the engine compart ­
ment" on
page 289.
The engine oil must be changed according to the intervals specified in
your Warranty
& Maintenance booklet. This is very important because
the lubricating properties of oil diminish gradually during normal
vehicle use.
Under some circumstances the engine oil sho uld be changed more
frequently. Change oil more often if you drive mostly short distances,
operate the vehicle in dusty areas or under predominant ly stop-and­
go traffic conditions, or have your vehicle where temperatures remain
below freezing for extended periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time . This is normal and is not a
reason to change the oil more often than recommended .
Because of the problem of proper disposal, along with the special
tools and necessary expertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified
serv ice station.
If you choose to change your oil yourself, please note the following
important information: .,_

• Wear eye protection.
• To reduce the ri sk of burns from hot engine oil, let the engine
cool down to the touch.
• When removing the oil drain plug w ith your finger s, stay as far
away as possible. Always keep you r forearm parallel to the ground
to help prevent hot oil from runn ing down your arm .
• Drain the oil into a containe r designed for this purpo se, one
large enough to hold at lea st the total amount of oil in your

Engine cooling system
Coolant
The engine coo lant performs two functions: i t keeps the
en gine fro m overhe ating and i t protects the engine fr om
fre ezing in th e winter .
The cooling system is sea led and genera lly requ ires little attention .
Th e cool ing sy stem h as been filled at the f actory wit h a permanent
coo lant which does not need to be changed . T he coolant cons ists of a
mixt ure of water an d the manufacturer's glycol -basedcoolant ad di­
tive Gl2++ antifreeze w ith anticorros ion addit ives (50% for USA
mode ls; 60% for Canadian models). This mixture both ass ures the
necessary frost protect ion and p rotects meta l components in th e
eng ine's cooling system from co rrosion an d scaling. It also raises the
boiling point of the cool ant.
Do not red uce the concentration of the coolant in the summer by
add ing p la in water. The proportion of coolant additive must be at
least 50 % but not more than 60 %
to maintai n antifreeze protection
and coo ling efficiency. If the coolant frost pro tect io n i s too low, t he
coo lant co uld free ze and damage t he veh icle heating an d eng ine
coo ling system.
For yea r- round drivi ng , antifree ze is added at t he factory for tempe r­
atures dow n to:
• - 31°F( -35°C)USA
• -40
°F ( -40 °C) Canada .
You can mi x the Gl2+ + coo lant additive wit h other additives (G12 + or
Gl2) . Always check with you r autho rized Aud i dea ler .
