- The front spoiler also he lps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the engine speed is below 1,SOO RPM . The begin­
ning of the red zone in the tachometer indicates
the maximum permissible engine speed for all
gears once the engine has been broken in and
when it is warmed up to operating temperat ure.
Before reaching the red zone, you shou ld shift in­
to the next higher gear, choose the Dor S selec­
tor lever position, or remove your foot from the
accelerator pedal.
CD Note
The needle in the tachometer @Q page 8,
fig. 3 may only be in the red area of the gauge
for a short time or there is a risk of engine
damage.
@ For the sake of the environment
Upshifting ea rly helps you to save fuel and re­
duces operating noise.
Fuel level
The fuel level indicator only operates when the
ignition is switched on.
The
tD ¢ page 15 turns on if the reserve quan ­
tity of fue l is reached.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section ¢ page 210.
CD Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
Instruments and indicator lights
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheat ing and damage
to the catalytic converter.

A WARNING
-
Read and follow all WARNINGS.
-The vehicle can roll
even if the ignition is
switched off.
- Never select R or P while driving, because
this increases the risk of an accident.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must keep your foot on the brake in all selector
lever positions (except P) when the engine is
running .
- Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged . Otherwise, the vehicle will imme­
diately start to
move -sometimes even if
the parking brake is firmly applied. This in­
creases the risk of an accident.
- To reduce the risk of an accident, do not
press the accelerator pedal when changing
the selector lever position while the vehicle
is stationary and the engine is running.
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- Before you or other persons open the hood
and work on a running engine, the selector
lever must be in the P position and the park­ ing brake must be applied to reduce the risk
of an accident . Always read and follow the
applicable warnings ¢

Gasoline grade
A pp lies to: ve hicles w ith gaso li ne engines
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unleaded ga soli ne.
Aud i recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gaso line can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/
2 equating to AK I or in RON.
The fo llow ing headings match the co rrespon ding
sticker in the fue l fi ller door .
UNLEADED FUEL ONLY MIN . (R+M) /2 87

- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades a re blended to pe rform es­
pec ially well for w in ter o r su mme r dr iv ing . D ur ­
i ng seasonal change-ove r, we s ugges t th at yo u
fill up at busy gas stat ions where the seasona l
adjustment is more likely to be made in time.
(D Note
- Meth ano l fuels which do not meet these re­
q uirements may cause corrosion and dam ­
age to plastic and rubber com ponents in the
fuel system.
- Do not use fue ls that fa il to meet the speci­
