The instrument illumination for the needles
and d ials t urns on when the ignition is turned
on and the lights are turned off. The illumina­
tion fo r the ga uges reduces automat ical ly and
eventu ally turns off as brightness outside in­
creases . This function reminds the drive r to
turn the low beams on at the appropriate
time.
Coolant temperature indicator
~ The coolant temperature display (D ¢ page 9,
§ fig . 3 only functions when the ignition is switch­
<.,:, ' ed on. To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold ran ge
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high eng ine speeds, full ac­
celerating and heavy eng ine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on.
If the . indicator light in the instru­
ment cluster d isplay turns on, the coolant tem­
perature is too
high ¢ page 13.
@ Note
-Aux iliary headlights and other accessories in
front of the coo ling-air intake impa ir the
cooling effect of the coolant . This increases
the risk of the engine overheating dur ing
high ou tside temperatures and heavy en­
gine load.

Instrum ent s and ind icat or light s
-The front spoiler also he lps to distribute
cooling air while driving . If the spoiler is
damaged, the cooling effect w ill be im­
paired and the r isk of the engine overheat­
i ng will increase. See an author ized Audi
dealer or authorized Audi Service Fac ility for
ass istance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the speed is below 1,S00 RPM. The beginn ing 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 temperature. Before
reaching the red zone, yo u should shift into the
next higher gear, choose the Dor S se lector lever
position, or remove your foot from the accelera ­
tor peda l.
@ Note
The needle in the tachometer @ ¢ page 9,
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 early he lps you to save fuel and re ­
duces operating noise.
(D Tips
Applies to: S models
The engine speed is limited when the eng ine
is cold - the full engine output is not availa­
ble. When the engine is at operating temper­
ature, the red area in the tachometer moves
to a hig her RPM range .
Fuel level
The display @ only wo rks when the ignition is
sw itched on. If the fuel level d rops below 2 .6 gal
(10 li ters), a red L ED w ill tur n on and t he
rD indi ­
cator light will turn
on ¢ page 17. The LED
blinks red when the fuel leve l is very low .

Instruments and indicator lights
• Coolant temperature too high! Please let en­
gine run with vehicle stationary
Let the engine run at idle for a few minutes to
cool off, until the indicator light turns off.
- If the indicator light does not turn off, do not
continue driving the vehicle. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.
A WARNING
- Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can be a dangerous area. Stop the engine and
allow it to cool before working in the engine
compartment. Always follow the informa­
tion found
in¢ page 189, Working in the
engine compartment.
@ Note
Do not continue driving if the. indicator
light turns on as this increases the risk of en­
gine damage.
~ Front safety belt
The. indicator light stays on until the driver's
and front passenger's safety belts are fastened.
Above a certain speed, there will also be a warn­
ing tone.
(D Tips
For additional information on safety belts,

0 Alternator/vehicle battery
• Electrical system: malfunction! Battery is
not being charged
There is a malfunction in the alternator or the ve­
hicle electrical system.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately. Because the ve-
14
hicle battery is discharging, turn off all unneces­
sary electrical equipment such as the radio. See
an authorized Audi dealer or authorized Audi
Service Facility if the battery charge level is too
low.
(•) low battery: Battery will be charged while
driving
The starting ability may be impaired.
If this message turns off after a little while, the
vehicle battery charged enough while driving.
If the message does not turn off, have an author­
ized Audi dealer or authorized Audi Service Facili­
ty repair the malfunction .
~ Engine stop while driving
• Engine stopped: No power steering and
brake support.
There is a malfunction in the engine or in the fuel
supply system.
More force is needed to steer and brake the mov­
ing vehicle when the engine is stopped . If the
ve·
hicle is rolling, try to bring it to a stop off to the
side from moving traffic. See an authorized Audi
dealer or authorized Audi Service Facility for as­
sistance.
A WARNING
If the engine stops while driving, you will
need to use more force to brake the vehicle.
This increases the risk of an accident. There
will still be power steering if the ignition is
switched on while the vehicle is rolling and
there is sufficient battery charge . Otherwise,
you must use greater force when steering.
~ Engine oil pressure
• Turn off engine and check oil level
Stop the engine and do not continue driving.
Check the engine oil
level¢ page 193.

- If the engine oil level is too low, add engine oil
¢ page 194 . Only continue driving once the in-
dicator light turns off.

! ?) Engine speed limitation
Applies to: ve hicles with eng ine speed lim itat ion
Ill Maximum engine speed: XXXX rpm
The engine speed is automatically limited to the
speed displayed in the instrument cluster. This
protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature range and you have released the accelerator ped­
a l once.
If the engine speed limitation was activated by
an engine contro l ma lfunction, the
ll:a indicator
light also turns on. Make sure that the speed
does not go above the speed displayed. Drive to
an author ized Audi dealer or authorized Audi
Service Facility immediately to have the malfunc­
tion corrected .
Q) Tips
Applies to: S models
The engine speed is limited when the engine
is cold
-the full engine output is not availa­
ble. When the engine is at operating temper­
ature, the red area in the tach ometer moves
to a highe r RPM range.

r~
Fig . 64 Attachment poi nts for the roof rack
If luggage or cargo is to be carried on the roof,
you must observe the following:
-Only a specia lly designed roof ra ck may be used
o n your veh icle. These roof racks are the basis
for a complete roof rack system. Additional at ­
tachments/carrier systems are necessary to
transport luggage and sports equipment. We
recommend roof racks and attachments from
the Audi Genu ine Accessor ies program.
-When installing the roof rack, make sure that it
is mounted only at the designated points on
the roof
i:> fig. 64 .
-Note the perm itted axle load, permitted total
weight, and permitted roof load of your vehicle
<=> page 246. The roof load is the tota l of the
weight of t he roof rack, the attachments and
the cargo you are carrying. However, you must
also note the permitted load of the carrier sys­
tem being used .

A WARNING
,-
-Follow the installation instructions provided
w it h the roof rack system. If you do not se­
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and ca use an accident .
-Using a roof rack system increases the r isk
of an accident, because it changes the ve hi­
cle handling characte rist ics wh ile driving by
shifting the center of grav ity and/or the in­
creasing the sur face area exposed to wind .
You may need to adapt your driving sty le
and speed to the current conditions.
CD Note
Make sure that the luggage compartment lid
and the sunroof* do not come into contact
with objects on the roof when they are open .
@ For the sake of the environment
Your vehi cle will require mo re fuel d ue to the
increased wind resistance. So remove the roof
rack after using it.
