Starting and stopping the engine
Starting the engine
The engine can only be started with on original Audi key
and the clutch pedal* depressed.
- Set the parking brake.
Move the selector lever to the neutral position (automatic
transmission: selector lever in P or N)
~ & .
- On vehicles with manual transmission, fully depress the
clutch pedal.
- Turn the ignition key to position
G) ~ page 106, fig. 101
- do not depress the gas pedal when starting the engine!
- Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure . This normal
and no need for concern.
If the engine does not star t immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled .
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.
Controls and equip ­
ment
0 Note
• Avoid high engine speeds, fast acceleration or heavy engine
loads while the engine is still cold. This could damage the engine.
• The engine cannot be started by pushing o r towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emis­
sions, do not let your vehicle stand and warm up. Be ready to drive
off immediately after starting your vehicle. Maintain moderate
speed until the engine is completely warm. Remember, the engine
performs best at operating temperature. •
Stopping the engine
-Turn the ignition key to position G) ~ page 106 , fig. 101.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running . With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up in the engine
compartment. .,

•
High temperatures, as from exposure to intense sunlight, intens ify
the corrosive effect particularly when humidity is high as well.
Under ce rtain circumstances ,
weekly washing may be necessary .
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the
underside of the vehicle should be thoroughly
washed preferably in a professional car wash .
& WARNING
Always read and heed all WARNINGS and the information
=>
page 200 . •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However , the
effect on the paint depends to a large extent on the design of the
facility, the filtering of the wash water, the type of wash and care
material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash .
The power top does not require specia l precautions before passing
through a car wash.
However, the car must not be treated with hot
wax after the wash cycle!
The wax could adversely affect the power
top and even damage the fabric over a period of time.
The power top do es not have to be washed every time you use a car
wash . The power top can be spared if the car wash facility is
equipped with manually adjustable roof brushes or rollers.
Before going through a car wash, be sure to take the usua l precau ­
tions such as closing the windows. Remove antenna if applicable . If
you have installed additional accessories on the vehicle -such as
spoilers, etc. -it is best to ask the car wash operator if these should
be removed.
& WARNING
Always read and heed all WARNINGS and the information
=> page 200. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
-Before you start washing, make sure you have read and
understood the WARNINGS ::}
& in "General informa­
tion" on
page 200.
-First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work
your way down to the bottom, using a sponge, a sponge
glove or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt .
- Rinse the car thoroughly with water.
- Use a chamois leather to gently wipe the exterior dry.
Use a separate sponge for cleaning the wheels, door si lls and other
regions exposed to road dirt. In this way, you will not scratch the
paint with coarse particles imbedded in the sponge the next time
you wash the car . .,,

At the time of printing, engine oils available in the U.S . and Canada
t hat meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils . This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So
always be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the follow ing spec ifica tions pr inted on the oil container:
Au di oi l stan dar d VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and o il quality standards.
V isc osit y
Engine oils are graded according to their viscosity . The proper
viscosity grade oi l for your engine depends on climactic or seasona l
conditions where you drive . You can use oil with a v iscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi ­
tions.
However, if eng ine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil qua lity standard VW 502 00 specifications .
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we s trong ly recommend
that you a lways carry with you an extra quart ( liter) of oil that
expressly conforms to the VW 502 00 specification, in case you have
to top off the o il while on the road.
On ly if the level of the oil is at or below the minimum mark on the
oi l dipstick -and no oil that express ly conforms to Audi oi l standa rd
VW 502 00 specifications is available -may you top off with a high
qual ity engine oi l, preferably synthetic -based, t hat meets ACEA A3,
ACEA A5 or ACEA 85, API SL or ILSAC GF -3 specifications, but even
then, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, dur ing the entire time between oi l change intervals, never
top off w ith more than a total of 0.5 qt/liter engine oil that does not
confo rm to Audi oil specificat ion VW 502 00. For more information about engine oil that has been approved for
your vehicle, p lease con tac t ei the r your authorized Audi dea ler or
Aud i Customer Relations at 1 (800) 822-2834 or visit our web site at
www .audiusa .com or www .audicanada.ca. Here you will a lso find a
current list of oils (manufacturers, brand names etc.l that conform
to Audi oi l standard VW 502 00 .
Changing the engine oil
The engine oil and oil filter must be changed according to the
mi leage (k ilometers) and time intervals specified in your vehic le's
Maintenance
& Warranty booklet. Do not exceed these intervals -
harmfu l deposits from old engine oil can reduce engine perfor­
mance and can lead to expens ive eng ine repairs.
Changing the oil at the recommended interva ls is so very important
because the lub ricating properties of oi l decrease gradua lly during
normal vehicle use. If you are not sure when you have your oil
changed, ask you r authorized Audi Service Advisor .
Under some circumstances the engine oil should even be changed
more frequently. Change oi l mo re often if you drive mostly short
distances, operate the vehicle in dusty areas o r mostly under stop­
and -go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long per iods.
Detergent additives in the oil will make fresh oi l look dark after the
engine has been running for a sho rt time. Th is is normal and is not
a reason to change the oil more often than recommended.
D amag e or malfun ctions due to la ck of mai nten ance
It is essential that you change your oi l at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to failure to fol low recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Maintenance
& Warranty booklet . Your dealer wi ll 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 de pen ds on an ade quate
amount of oil to lubric ate and co ol all of its moving parts.
In order to provide effective lubrication and cooling of interna l
engine components, al l internal co mbustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ificant ly over the life of the engine . Typ ical ly,
engines with a specified break -in period (see=>
page 192) consume
more oil duri ng the brea k-in period than they consume afte r oil
consumption has stabi liz ed.
Unde r no rmal conditions, the rate of oil consumption depends on
the quality and viscosity of t he oil, the RPM ( revo lutions per m inute)
at which the engine is operated, the ambient temperature and road
co nd itions. Further factors are the amount of oi l dilut io n from water
condensation or fue l residue and the oxidation leve l of the oil. As
any e ng ine is subject to wear as mil eage builds up, the o il consump ­
tion may increase over time until replacement of worn components
may become necessary .
With all these var iables com ing into p lay, no standard rate of oil
consu mption can be es tab lished or speci fied. There is no a lternative
t o regular and frequent checking of the oi l leve l, see Note.
If the yellow engine oi l level warning symbol in the instrumen t
cluster _ lights up, y ou should check the oil level as soon as
possible
with the oil dipstick=> page 224. Top off the oil at your
ea rlies t conve nience =>
page 225.
ln. WARNING
Before you check anything in the engine compartment , alway s
re ad and heed all WARNINGS =>
& in "Working in the engine
c ompartment" on

0 Note
D riving with an insufficient o il level is lik ely to cause seve re 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 , preferab ly ea ch time you refuel , and alw ays before
going on a long trip.
• I f you have the impression your engine consumes excessive
a m oun ts o f oi l, we recommend tha t you consu lt your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the acc urate measure ment o f oil co nsum ptio n requires grea t
care and may take some time . Your Audi dea ler has instructions
about how to measu re oil consump tion accurately. •

• The auxiliary electric fan is temperature controlled and can
switch on suddenly even when the engine is not running.
• The auxiliary radiator fan switches on automatically when the
engine coolant reaches a certain temperature and will continue to

Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick glance.
Fig. 155 Engine
compartment: brake
fluid reservoir
Before you check anything in the engine compartment,
always read and heed all WARNINGS =>
& in "Working in
the engine compartment" on
page 220.
- Read the brake fluid level from the brake fluid reservoir
~ fig. 155. The brake fluid level must be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is located behind the rear partition of the
engine compartment on the left side~
page 221 .
The fluid level may drop slightly after some time due to the auto­
matic 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 (U .S. models:
BRAKE , Canadian models:
ill) will come on~ page 20 and~ page 32. Do not continue to
operate the vehicle . The complete brake system should be thor­
oughly 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 illuminate. Contact an authorized
Audi dealer
immediately .•
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the air. If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The boiling point of the brake fluid will als o
decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan ­
dard "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 autho­
rized
Audi dealer . Your dealer has the correct tools, the right brake
fluid and the know -how to do this for you.
& 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 inappropriate brake fluid.
Observe these precautions : .,,_

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, etc., some service work
should be performed between the intervals specified . This applies
particularly to:
• oil changes , and
• cleaning or replacing the air filter.
~ For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis ­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners. Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_
