New brake pads
--
Remember that new brake pads do not have a full braking
effect during the first 250 miles (400 kilometers) after they
are installed .
New brake pads have to be "burnished in" before they have optimal
grab =>& .
During the break -in period, you should avoid putting severe loads
on the brakes . Severe loads include, for examp le, sudden hard
braking, in particular at very high speeds or, for example, on moun­
tain passes.
& WARNING
New brake pads don't have the best stopping power and must be
"broken-in" during the initial 100 to 150 miles (150 to 200 kilome­
ters) of normal city driving. You can compensate for this by
pressing the brake pedal more firmly . This also applies later when
new pads are installed.

Catalytic converter
It is very important that your emission control system
(catalytic converter) is functioning properly to ensure that
your vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline:=> page 291, "Fuel supply".
- Never run the tank down all the way to empty.
- Never put too much motor oil in your engine ==>
page 302,
"Adding engine oil 't=:;r\11
•
Never try to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up" device built into the
exhaust system of the vehicle. The catalytic converter burns many
of the po llutants in the exhaust gas before they are released into the
atmosphere.
The exclusive use of unleaded fuel is critically important for the life
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust system may come in contact with dry grass, brush, fuel
spill or other material which can cause a fire .
• Do not apply additional undercoating or rustproofing on or
near the exhaust manifold, exhaust pipes, catalytic converter or
heat shields. During driving, the substance used for undercoating
could overheat and cause a fire .
0 Note
• Be aware that just one tank filling with leaded fuel will alr eady
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level=>
page 302.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the catalytic converter. This could result
in overheating of the converter, requiring its replacement .
• To assure efficient operation of the Emission Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Maintenance
& Warranty
booklet. •

one half. Never drive faster than the posted speed limit and weather
conditions permit. •
Reducing unnecessary =citing
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the engine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings , or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fuel than is burned starting the engine again .
It takes a long time for the engine to warm up fu lly when it is
running at idle. However, wear and noxious emissions are especially
high when the engine is warming up. So you should drive away as
soon as you start the engine and avoid running at high rpms while
the engine is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended idling also produces heat, which could result in overheating or other damage to the vehicle or other
property .•
Regu1ar ma1--.tenance
A badly tuned engine unnecessarily wastes a lot of fuel.
-Have your vehic le serviced at regular intervals .
By having your vehicle regularly serviced by an Audi dealer helps to
ensure that it runs properly and economically. The condition of your
vehic le not only affects its safety and abi lity to hold its value, it also
affects
fuel con sumpt ion.
C hec k your o il e ach time you fill your t ank.
The amount of oil used is related to engine load and speed.
It is norma l for the oil consumption of a new engine to reach its
lowest va lue after a certain mileage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption .
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
the service recommendations in your Maintenance
& Warranty
booklet. Lack of proper ma intenance as well as improper use of the
vehic le wi ll impair the function of the emission control system and
cou ld lead to damage.
• Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not alter or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
vehicle's Em ission Control System and other important vehicle
components .•
Fewer short tr ips
Fuel consumption will always be relatively high on short
trips.
- Try to avoid driving short dista nces wi th a cold engine. _,

from fading. Slight color variations will develop in normal use and
are not an indication of material deterioration.
0 Note
• Never use chemical solvents (e.g. lighter fluid, turpentine),
waxes, shoe polish or similar products on Alcantara ® surfaces.
• To avoid damage, have stubborn stains removed by a commer­
cial cleaning specialist.
• Do not use brushes, stiff sponges or similarly abrasive cleaning
aids .•
Safety belts
Only well-maintained safety belts work reliably when
needed.
- Keep belts clean.
- For cleaning, use a mild soap and water solution . Let
belts dry thoroughly and away from direct sunlight .
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash.
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them.
& WARNING (continued)
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your Audi dealer.
• Always read and heed all WARNINGS and other information

Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine ~ &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts.
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti -corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
1 l, or if you have the engine washed, the anti­
corrosion treatment is almost always removed as well. It is therefore .,_
11 Use only th e correct cleaning solut ions. N ev er use gasolin e or di ese l fu el.

because the lubricating properties of oil diminish gradually during
normal vehicle use .
Under some circumstances the engine oil should be changed more
frequently . Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or under predomi ­
nantly stop -and -go traffic conditions, or have your vehicle where
temperatures remain below freez ing for extended periods.
Detergent additives in the oi l 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 oi l more often than recommended .
Because of the problem of proper disposal, along with the specia l
tools and necessary expertise required, we strongly recommend
that you have your oi l changed by an authori zed
Audi dea ler or a
qual ified service stat ion.
If you choo se to cha nge yo ur oi l y ou rse lf, please no te the following
important information:
& WARNING
To reduce the risk of per sonal injury if you m ust change the engine
o il in you r veh ic le y our self :
• Wear eye protection.
• To reduce the ri sk of burn s from hot engine oil , let the engine
c ool down to the tou ch.
• When removing the oil drain plug with your fing ers , sta y as far
away as po ssi ble . Alw ay s k eep your f orearm par allel to the gr ound
to help pre vent hot oil from running down your arm .
• Drain t he oil int o a contain er de signed for thi s purpo se , one

0 Note
Never mix oil addi tives with your engine oil. These add itives can
damage your engine and adversely affect your Audi Limited New
Vehicle Warranty .
c£> For the sake of the environment
• Before changing your oi l, first make sure you know where you
can properly dispose of the us ed oil.
• Always dispose of used engine oil properly. Do not dump it on
garden soil , wooded areas, into open streams or down sewage
drains .
• Recycle used engine oil by taking it to a used engine oil collec ­
tion fac ility in your area , or contact a service station. •
Engine cooling system
Coolant
The engine coolant performs two functions: it keeps the
engine from overheating and it protects the engine from
freezing i n the winter.
The cooling system is sea led and generally requires little attention.
The coo ling system has been fi lled at the factory with a permanent
coolant which does not need to be changed . The coolant consists of
a mixture of water and the manufac turer's glycol-basedcoolant
additive G 12+ an tifreeze with anticorrosion additives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects metal components in the
engine 's cooling system from corrosion and scaling . It also raises
the boiling point of the coolant.
Do not reduce the concentration of the coo lant in the summer by
adding plain water.
The p ropo rt ion of co ola nt additiv e mu st be at .,_

le as t 50% b ut not mor e th an 60 % to maintain antifreeze protection
and cooling efficiency . If the coo lant frost protection is too low, the
coo lant could freeze and damage the vehicle heating and engine
cooling system.
For year -round driving, antifreeze is added at the factory for temper­
atures down to:
• -31 °F ( -35 °C) USA
• -40 °F ( -40 °C) Canada.
You can m ix the
Gl 2 + coolant additive with other add itives (for
example
Gl 1 or Gl 2). A lways check with your authorized Audi
dea ler .
& WARNING
Before you check anyt hing in the engine comp artment , alw ays
re ad and heed all WARNINGS ~
& in "Working in the eng ine
co mpar tm ent " o n
pag e 297.
0 Note
• Before win ter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especia lly important if you live in a region where
the winter is extremely cold. I f necessary, increase the proportion of
coo lant additive to 60%.
• When adding coolant additive to your coo ling system,
remember:
-We recommend using only coolant additive
Gl 2+ (check the
label) for your vehicle. This coolant addit ive is available at autho ­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protect ion . T he resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adversely affect the function and performance of your cooling system and cou
ld result
in damage not c overed by your New Vehicle Limited Warranty. •
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.

Before you check anything in the engine compartment,
always read and heed all WARNINGS~
& in "Working in
the e ngin e compa rtment" on
page 297 .
Turn off the ignition.
Re ad the en gine coo lant leve l from the coo lant exp an­
sio n ta n k~ fig. 235. With a cold eng ine, the coolan t leve l
sho uld be between the "m in" and "max" markings. W hen

"max" marking .
The location of the coolant expansion tank can be seen in the
engine compartment illustration~
page 298.
To obtain an accurate reading, the engine must be switched off .
T he expansion tank in your vehicle is equipped with an e lectric
coo lant leve l sensor.

•
When the coolant level is too low , the warning light in the Auto­
Check System =>
page 33will blink un til you add coo lant and the
level has been restored to normal. Even though there is an electric
coolant leve l sensor, we still recommend you check the coo lant level
from time to time .
Coola nt lo ss
Coolant loss may indicate a leak in the cooling system . In the event
of coolant loss, the coo ling sys tem should be inspected immedi ­
ately by your authorized Audi dealer . It is not enough merely to add
coolant.
In a
s ealed system, losses can occur only if the boiling po int of the
coolant is exceeded as a result of overheating.
0 Note
Do not add any type of radiator leak sea lant to your vehicle's engine
coolant . Adding radiator repair fluid may adversely affect the func ­
tion and performance of your cooling system and could resu lt in
damage not covered by your New Vehic le Limited War ranty .•
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS => & in "Working in
the engine compartment" on
page 297 .
- Tu rn off the engine .
- L et the engine coo l dow n.
- Place a t hick rag over the coolant expansion tank
=> page 304, fig . 235 and carefully tw ist t he cap counter­
cloc kw ise
=> & .
- Add coolant. - Twist the cap
on agai n
tightly.
Replacement engine coolant must conform to exact specifications
=>
page 303, "Coolant". If in an emergency coolant additive G12 + is
not avai lable, do
not use a different additive . Use p lain water
instead until you can get the correct additive and can restore the
correct ratio . This should be do ne as soon as possible.
If you have lost a considerable amount of coolant, then you should
add cold antifreeze and cold water only when the engine is cold .
Always use
new engine coolant when refilling .
Do not fil l coolant above the "MAX" mark. Excess coolant will be
forced out through the pressure relief va lve in the cap when the
engine becomes ho t.
& WARNING
• The cooling system is under pressure and can get ver y hot.
Redu ce the risk of sc alding from hot coolan t by follow ing the se
s tep s.
- Turn off th e en gine and allo w it to cool down .
- Protect your fa ce , ha nd s and arm s from e sc a pi ng fluid and
