Driving and environment
The first 1,000 miles (1,500 km) and afterwards
!\Jew engine
The engine needs to be run-in during the first 1,000 miles
(1,500 km).
F o r th e fir st 600 mil es (1,000 kilomet ers):
Do not use full throttle.
- Do not drive faster than 3/4 of the top speed marked on
the speedometer.
- Avoid high engine speeds .
From 600 t o 1,000 mil es (1,000 t o 1,500
kil om eter s):
- Speeds can gradually be increased to t he maximum
permiss ible road or engine speed .
During and aft er br eak-in p eri od
- Do not rev the engine up to high speeds when it is cold. This applies whether the transm ission is in N (Neutral) or
1n gear.
Aft er the br eak-in p eriod
- D o not exceed max imum e ngine speed unde r any
circumstances.
- Upshift into the next higher gear before reaching the red
area at the end of the tachome ter scale

Dri
ving and environm ent
During the first few hours of driving, the eng ine's internal friction is
higher than later when all the moving parts have been broken in.
How well this break -in process is done depends to a considerable
extent on the way the vehicle is driven during the first 1,000 miles
(1,500 ki lometers).
0 Not e
Extreme ly high engine speeds are automatically reduced. However,
these RPM -limits were programmed for an engine we ll run-in, not a
new engine .
~ For the sake of the environment
Do not drive with unnecessarily high engine speeds -upshifting
early saves fuel, reduces noise and protects the environment .
New tires
If your v ehic le is running on new tires, driv e particularly
carefu l for the first 300 miles (500 ki lometers) after fitting.

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
Until they develop the maximum "bite " for best stopping power,
the surfaces on new brake pads require some "breaking -in" during
the initial 100 to 150 miles (150 to 200 kilometers) of normal city
driving. You can compensate for this by pressing the brake pedal
more firmly . This applies whenever 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 219, "Fuel supply".
- Never run the tank down all the way to empty.
- Never put too much motor oil in your engine ==>
page 230,
"Adding engine oil 't=:;rl".
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 230.
• 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 Warranty
& Maintenance
booklet. •

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission con tro l system
and could lead to damage.
<£> For the sake of th e envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
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 spoi lers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) and fully loaded vehicles. •
Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating cond itions
• technica l limitations

ment Safety first Vehicle operation
Dri
ving and environm ent
If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumpt ion by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketbook.
[ i ] Tips
The consumption estimates as published by ENV IRONMENTAL
PRO TEC TION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating.
Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car's max imum speed.
Acce lerating gently reduces fue l consumption , engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximate ly
three quarters of top speed, fuel consumption wil l be reduced by

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 authori
zed Audi
dea ler helps to ensure that it runs properly and economica lly. The
condition of your vehicle not only affects its safety and ability to
hold its value, it a lso affects
fu el con sumpti on.
C he ck your oil each 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 .
T his also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
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 Emiss ion 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. _,

The engine and catalytic converter have to reach their optimal ope r­
at ing t emp era tur e
to reduce fuel consumption and noxious emis ­
sions effectively .
• Just after starting, a cold engine in a mid -size car burns the fuel
at a poor rate of 6-8 miles per gal lon (30-40 11100km). Half a mile
down the road, the mileage improves to 12 MPG (201/100 km). It will
take the eng ine no less than
two and a half miles (4 km) of driv ing to
warm up to its proper operating temperature and operate at an
economic mileage. This explains why taking the car for short trips is
a rather wasteful convenience.
• The
out sid e tem perature is also critical in th is regard . Your car
consumes more fuel in the winter than in the summer.

Trailer lights
Trailer lights must meet all regulations. Be sure to check with your
authorized Audi dealer for correct wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you using the regular
outside mirrors, then you
must install extended mirrors. It is impor­
tant that you
always have clear vision to the rear .
& WARNING
After removing the trailer hitch, do not store it in your vehicle. In
case of sudden braking, the hitch could fly forward and injure you
or your passengers .

Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical class 1 or class 2
trailer.
Trailer load distribution
Be sure the load in the trailer is held securely in place to guard
against shifting, be it forward, backward or sideways.
Never allow a passenger to ride in a trailer:::::, & in "Driving instruc­
tions".
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the sticker on the right door­
jamb. Inflate trailer tires to trailer and tire manufacturers' specifica­
tions.

Trailer towing
Lights
The
headlight settings should be checked with the trailer attached
before driving off. Adjust as necessary so that you can see the road
ahead but not blind oncoming traffic.
Check proper working of vehicle and trailer lights.
Safety chains
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
permit turning corners. When you install safety chains, make sure
they will not drag on the road when you are driving.
The chains should cross under the trailer tongue to prevent it from
dropping in case of separation from the hitch. •
Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other vehicles.
Observe speed limits.
Do not drive at the maximum permissible speed.
- Always apply brakes early.
Monitor the temperature gauge.

Parking on a slope
-----------------
Do not park with a trailer on a slope. If it cannot be
avoided, do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle and the trailer wheels .
- With chocks in place, slowly release the brakes until
wheel blocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake.
- Place an automatic transmission in
P, respectively a
manual transmission in first or reverse gear.
When restarting after parking:
- Start the engine.
- Shift transmission into gear.
- Release the parking brake and slowly pull out and away from the wheel blocks.
- Stop and have someone retrieve the wheel blocks.

Fuel supply and filling your fuel tank
Blend of gasoline and ethanol (grain alcohol or ethyl alcohol}
• Anti -knock index must be 87 AKI or higher.
• Blend must not contain more than 10% ethanol.
Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well for
winter or summer driving. During seasonal change -over, we suggest
that you fill up at busy gas stations where the seasonal adjustment
is more likely to be made in time.
0 Note
• Methanol fuels which do not meet these requirements may
cause corrosion and damage to plastic and rubber components in
the fuel system.
• Do not use fuels that fail to meet the specified criteria in this
chapter.
• If you are unable to determine whether or not a particular fuel
blend meets the specifications, ask your service station or its fuel
supplier.
• Do not use fuel for which the contents cannot be identified.
• Fuel system damage and performance problems resulting from
the use of fuels different from those specified are not the responsi ­
bility of Audi and are not covered under the New Vehicle or the
Emission Control System Warranties.
• If you experience a loss of fuel economy or driveability and
performance problems due to the use of one of these fuel blends,
we recommend that you switch to unblended fuel. •
Gasoline additives
A major concern among many auto manufacturers is carbon
deposit build-up caused by the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another,
they have certain things in common . All gasoline grades contain
substances that can cause deposits to collect on vital engine parts,
such as fuel injectors and intake valves. Although most gasoline
brands include additives to keep engine and fuel systems clean,
they are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the offi­
cial website (www.toptiergas.com).
After an extended period of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance.
(D Note
Damage or malfunction due to poor fuel quality is not covered by
the Audi New Vehicle Limited Warranty. •

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of
oil.
The engine in your Audi is a sophisticated powerplant that was built
to exacting specifications . This engine needs the right kind of
engine oil that meets specifications regarding quality and viscosity
so that it can run smoothly and reliably. Choosing the right oil and
changing oil within the time and mileage intervals printed in your
vehicle's Warranty
& Maintenance booklet matters a lot more today
than it did years ago. Audi has developed a special quality standard
for engine oil that will help assure that your vehicle's engine will get
the lubrication it needs for proper operation .
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine
lubrication that can outlast traditional petroleum-based oils,
making them a smart choice for use throughout the life of your Audi .
Whether you use synthetic or petroleum-based engine oil, the oil
that you use must conform to Audi's oil quality standard VW 502 00
to help keep your vehicle's engine running smoothly and help
ti,,,
Vehic le care I I irechnical data

-~_C_ h_e _c _ k_ i_n ...:::g::;...._ a_n_ d_ f_ i_ll _in -'g:::;.._ ___________________________________________ _
prevent the formation of harmful deposits, sometimes called
"sludge," that over time can lead to expensive repairs.
At the time of printing, engine oils available in the U .S . and Canada
that 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 following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal conditions where you drive. You can use oil with a viscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions .
However, if engine oil viscosity grade SAE 5W40 is not available, you
can also use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we strongly recommend
that you always 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 oil while on the road.
Only if the level of the oil is at or below the minimum mark on the
oil dipstick -and no oil that expressly conforms to Audi oil standard
VW 502 00 specifications is available -may you top off with a high
quality engine oil, preferably synthetic -based, that meets ACEA A3,
ACEA A5 or ACEA B5, 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, during the entire time between oil change intervals, never top off with more than a total of 0
.5 qt/liter engine oil that does not
conform to Audi oil specification VW 502 00.
For more information about engine oil that has been approved for
your vehicle, please contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa.com or www.audicanada.ca. Here you will also find a
current list of oils (manufacturers, brand names etc.) that conform
to Audi oil standard VW 502 00.
Changing the engine oil
The engine oil and oil filter must be changed according to the
mileage (kilometers) and time intervals specified in your vehicle 's
Warranty
& Maintenance booklet. Do not exceed these intervals -
harmful deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor.
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 traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long 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 .
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00 . Your New Vehicle Limited 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
Manual and Warranty & Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
