-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

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

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.

! ?) 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

the high-voltage ignition system.
- Do not under any circumstances give gas in­
advertently (for example, by hand from the
engine compartment) if the vehicle is sta­
tionary but the engine is running and a gear
is engaged. Otherwise, the vehicle will start
to move immediately and this could result
in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke.
- Never work near open flames.
- Always have a working fire extinguisher
nearby.
- All work on the battery or electrical system
in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable
- Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­ tor lever in the P (park) position first.
- Always proceed with extreme caution so that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginning
work and do not wear clothing that can
hang down into the engine.
- Limit your exposure to exhaust and chemi­
cals to as short a time as
possible~ &..

~ Switch only the ignition back on.
~ Wait approx imately two minutes.

(UJ) Note
The engine oil leve l mus t not be unde r the
"min" mark ing, as this will increase the risk of
engine damage.
(D Tips
The o il level indica tor in the disp lay is on ly an
informationa l display. If the o il level is too
low, a minimum oi l warning appears in the in ­
strument cluster. Add oil and close the hood.
The current oil level is d isplayed in the Info­
tainment system the next t ime the ignition is
sw itched on.
(D Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.S liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumpt ion may be h igher during the
first 3,000 miles (5,000 km). Because of this,
the eng ine oil level m ust be checked regu lar­
ly. I t is best to chec k each t ime yo u refuel
your veh icle and befo re long d rives .
Ch eck ing and F illing
-In order to prov ide effective lubrication and
cooling of interna l engine components, a ll
internal comb ustion engines consume acer ­
tain amount of oil. Oi l consumption var ies
from engine to engine and may change sig­
nificantly over the life of the engine . Typi­
cally, eng ines with a specified break-in peri­
od consume mo re o il du ring the break-in pe­
r iod than they consume afte r oil cons ump­
t ion has s tabilized.
-Under norma l co ndit io ns, the rate of oil
cons umption depe nds on the q ual ity and
vis cos ity of the oil , the R PM (revo lutions per
m inute) a t which the engine is operated, the
ambient temperature and road conditions .
Further factors are the amount of oi l di lu­
tion from water condensat ion or fue l resi­
due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds
up, the oil consumption may increase over
t ime until replacement of worn components
may become necessa ry.
-With all these var iables com ing into play,
no sta ndard rate of o il consumption can be
established o r specified. There is no a lter na­
ti ve to c hec king the oil leve l reg ularly and
frequently.
-If you have the impress ion your e ngine co n­
sumes excessive amo unts o f oil, we recom ­
mend that you consult an author ized Audi
dea ler to have the cause of your concern
properly diagnosed . Keep in mind that t he
acc urate measurement of o il cons umption
requires great care and may take some
time . An authorized Aud i dealer has instruc­
tions about how to measu re o il consump­
tion accurate ly.
