CHECK
button => page 16, fig. 7.
Starting the Auto-Che ck sequence
The Auto -Check
system => page 28 consistently monitors certain
individual functions and components of the vehicle when the igni­
tion is turned on and when the vehicle is moving .
With the ignition switched on, you can start the "Auto-Check
sequence" by pressing the CHECK button. You can perform an Auto ­
Check sequence both when the vehicle is at a standstill and the igni­
tion is switched on or when the vehicle is moving not faster than
3 mph (5 km/h).

When a first priority symbo l starts to
flash => page 28 or when a
defective light
bulb=> page 35, has been detected, you can press
the CHECK button to display the driver information. For example:
SWITCH OFF ENGINE , CHECK OIL LEVEL
The information disappears after approximate ly five seconds .
Setting the speed warning
By pressing the CHECK button you can set speed warning
1
=> page 36, "Speed warning 1: setting a speed limit" while the
vehicle is moving.

With the ignition on, briefly push button G) to disp lay the distance
remaining (miles/kilometers) until the next service is due. You can
recall the service countdown with the engine in idle or while driving
at a slow speed up to
3 mph (5 km/h). The remaining distance will
be upda ted every 300 miles (500 km):
On a new vehicle, or immediately after a service has been
performed, the following message will be displayed:
SERVICE IN---- Ml (KM) ---DAYS
For the first 300 miles (500 km) of driving after a service, the display
will keep showing dashes. This
is NOT a malfunction . Rather, the
system needs the mileage to (re-)adjust to your driving
style. Only
then can it start generating and updating figures for the distance and
days until the next scheduled service .

• when driving through tunnels
• in a tra ffic jam.
& WARNING
Do not use this setting for extended periods of time . The windows
could fog up since no fresh air can enter the vehicle.

General
Y o ur personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, env ironmental impact, and wear on your engine,
brakes and t ires largely depend on three factors :

• operat ing cond it ions
• technica l limitat ions

-Avoid unnecess ary accelerating and brak ing.

thus , acce lerate less. Let the vehicle coast whenever poss ib le -for

Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep we ll below your car 's max imum speed.
Acce lerating gent ly reduces fue l consump tion , engine wear, and
does no t disturb the environme nt.

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 re liably . Choosing the right oil and
changing oil within the time and mileage intervals printed in your
vehicle's Maintenance
& Warranty booklet matters a lot more today
than it did years ago. Audi has developed a special quality standard
f or engine oil that wil l help assure that your vehicle's engine wi ll 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 oi l quality standard VW 502 00
to help keep your vehicle 's engine running smoothly and help
.,_

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
condi tions where you drive. You can use oil wi th 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
Maintenance & Warranty 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 Limited New Vehicle 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 Maintenance & Warranty booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
