The illumination for the instrument cluster lights up whenever you
switch on the ign ition with the
ve hicle hea dlight s off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and wil l go out completely when the outside light is
very low. This feature is meant to remind you to switch on th e head ­
lights when outside light conditions become poor. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes) .
The tachometer 0 ~ fig. 2 is the left of the two large c lock -type
displays.
The engine turns at a speed
1,000 times the single digit in the
display, e.g . if th e ne edle is pointing a t the
"2" the engine is turning
at 2,000 RPM .
If engine RPM drops below 1,500, you should downshif t to the next
lower gear . The red ar ea at the end of th e scale indica tes maximum
permissible engine RPM after the break- in period. Before reaching
th is area , shift into the next higher gear (manua l transmission),
move the selec tor lever to position "D (Drive)" (automatic) or ease
your foot off the accelerator pedal.
0 Note
T he tachometer need le should not move into the red range . If it
does, then on ly for a very short period of time . You could damage
your engine by driving a t high RPM. ...

If, however, the Malfunction Indicator Lamp (MIU comes on,
always drive to your nearest authorized Audi dealer or qualified
workshop and have the vehicle checked.

The service interval display detects when which service category is
required for your vehicle. It works in two stages:

service event, this message appears when the ignition is switched
on:

nied by a warning signal. And the type of service needed is
displayed.

uled service will be displayed.
For new vehicles or after the vehicle has been serviced, the next

Fuel supply and filling your fuel tank -___________ ...:._:......:,_______;::;...a,__ __
•
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 seasona l change -over, we suggest
that you fil l 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 p lastic and rubber components in
the fue l system.
• Do not use fue ls that fail to meet the specified criteria in this
chapter .
• If you are unable to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
suppl ier.
• Do not use fue l for which the contents cannot be identified.
• Fuel system damage and performance problems resu lting 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
depos it 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 gaso line grades contain
substances that can cause deposits to collect on vita l engine parts,
such as fue l injectors and intake valves. Although most gasoline
brands include additives to keep engine and fue l systems clean,
they are not equally effective.
Audi recommends using TOP TIER Detergen t Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the offi­
cial website (www.toptiergas .coml.
A ft er an extended period of using inadequate fuels, built-up carbon
deposits can rob you r engine of peak performance.

Damage or malfunction due to poor fuel qua lity is not covered by
