A WARNING
-Always observe the warning in¢ page 195,
before open ing the hood and check ing the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
cou ld burn yourself. Let the eng ine cool off
first so that you cannot hear o r see any
steam o r engine coo lant.
0 Note
- Mount ing additional lights or accesso ries in
fron t of the a ir inlets reduces the cooling ef­
fect of the radia to r. A t high outside temper­
atu res or high e ngine load, the eng ine could
overheat.
- The front spo iler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving. If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­ ized Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops be low 1,5 00, you should
downshift to the next lower gea r. T he red area at
the end of the scale indicates max imum permis­
sible eng ine RPM after the break-in period . Be­
fore reachi ng this area, move the selector lever to
position D/S or ease your foot off the accelerator
pedal.
(D Note
The tachometer needle@¢ page 10, fig. 3
should o nly briefly be in the red zone: you
co uld damage your eng ine! The beginn ing of
the r ed zone varies depending on the engine.
@ For the sake of the environment
Upshift ing early saves fuel and reduces eng ine
noise .
Instrument s and indi cator ligh ts

with the igni tion off .
Starting the Auto-Check sequence
The Auto-Check system constantly monitors cer­
tain individual functions and components of the
vehicle when the ignition is turned on and when
the vehicle is moving .
With the ign ition turned on, you can start the
"Auto-Check sequence" by pressing the
I SE TI but­
ton. You can perform an Auto-Check sequence
when the vehicle is sta tionary and the ign it ion is
tu rned on o r whe n th e vehicle is moving slowe r
t h an 3 mph (5 km/ h).
In add ition , the number of keys init ia lised for
your vehicle is disp layed .
L2 3/3 means that
th ree keys have be en initialised. This feature ena­
bles used car buye rs to make sure they have r e­
c e ived all of the keys.
If you are g iven only two keys, for instance, you
should take the vehicle and the existing keys to
an a utho rized Aud i dea le r to have the miss ing key
disabled.
It i s also important to no tify your insur­
ance company abo ut the loss.

Digital clock/GPS controlled clock*
Depending on the vehicle equipment level, you
may choose between the quartz clock or the GPS
controlled clock*~ in the radio or in the MMI*.
You can learn more about this in the MMI manual
or in the radio user's manual.
Odometer/trip odometer
The display of distance driven is shown in kilome­
ters "km" or in miles "mi".
- USA models -Miles
- Canada models - Kilometers
The units of measure (kilometers/miles) can be changed in the radio or MMI* . You can learn more
about this in the MMI manual or in the radio us­
er's manual.
The odometer @ shows the total number of kilo ­
meters or miles that have been driven on the ve­
hicle .

The trip odometer @ shows the distance driven
since it was last reset.
It can be used to measure
short distances. The last digit shows distances of
100 meters or 1/10 of a mile .
The trip odometer can be reset to zero by press­
ing the reset button

(D Note
Never run the tank completely dry! An irregu­
lar supply of fuel can cause engine misfiring
and fuel could enter into the exhaust system.
The catalytic converter could then overheat
and be damaged.

9:::1: Engine oil pressure
The red engine oil pressure warning symbol re­
quires immediate service or repair . Driving with a
low-oil-pressure indication is likely to inflict se­
vere damage to the engine.
• Turn off engin e! Oil pressure too low
If the indicator light t urns on and the message
appears, the oil pressure is too low.
• Pull
off the road.
• Stop the vehicle .
• Turnoff the engine.
• Check the engine oil level ¢ page 199.
• If the engine oil level is too low, add engine oil
¢ page 199. Make sure that the o il pressure
warning symbol. appears no longe r in the
display before you start dr iving again.
• If the engi ne oil leve l is correct a nd the ind ica­
tor light st ill turns on, turn the eng ine
off and
do not continue driving . Seek p rofess ional as ­
s istance .
(D Tips
- The engine oil pressure symbol. is not
an indicator for a low engine oil level. Do
not rely on it. Instead , check the oil level in
your engine at regular intervals, prefe rably
each time you refuel, and always before
going on a long trip.
- The yellow oil level warning indication
Ill
requires oil refill or workshop service with ­
out delay. Do not wait until the red oil pressure warning. starts to flash before
you respond to the low oil leve l warning
Ill . By then , your engine may already have
suffered serious damage.

Driver information system
Trip computer
Introduction
The trip computer gives you information on cur­
rent and average fuel mileage , average speed ,
fuel range and driving time .
Fig. 9 Trip computer d isplay: Ave rage fuel m ileage
~ 9 a: CX) m
The fo llow ing information is contin uously evalu­
ated by the trip computer and can be d isplayed
sequent ia lly in the instrument cluster display:
Fuel range
The estima ted c ruising range i n miles (km) ap­
pea rs in the disp lay . This te lls you how fa r your
ve hicle w ill be able to trave l on t he current ta nk
of fuel and with the same driv ing style. The d is­
p lay changes in increments of 5 miles (10 km) .
The cruising range is calcu lated based on t he f ue l
consumption for the last 18 m iles (30 km). If yo u
drive conse rvative ly, the cruising range will in­
crease.
Average fuel mileage
The average fuel e co nomy in MPG (l/ 100 k m)
since yo u last cleared the memory appears in this
d is pl ay. You can use this display to ad just your
driving technique to achieve a desired mileage.
Current fuel mileage
The inst antaneo us f ue l cons umption in miles per
ga llon (l/100 km) is shown in this display. Yo u
can use t his disp lay to adjust your driving techni­
que to achieve a des ired mileage .
F ue l cons umption is rec alcul ated at intervals of
33 y ards (30 me ters). Th is disp lay swit ches to
