on and the lights are tur ned off . The illumina­

Coolant temperature indicator
"'

;::) a,
"'
The coolant temperature indicator@~ page 10,
fig . 3
only operates when the ign ition is switched
on. To prevent engine damage, please observe
the following notes about the temperature rang­
es .
Cold range
If the needle is at the bottom of the gauge, the
engine has not reached operating temperature
yet. Avoid high engine speeds, full accelerating
and heavy engine loads.
Normal rang e
The engine has reached operating temperature
when the needle moves into the center of the
gauge under norma l dr iving condit ions. The nee­
dle may move farther to the right on the gauge
with heavier engine load at high outside temper­
atures . This is no cause for concern as long as the
• indicator light in the instrument cluster does
not turn on . If the needle is fa r over on the r ight
s ide of the gauge and the . indicator light tu rns
on, then the coolan t temperatu re is too high
~ page 14. ..,.

& WARNING
-Always observe the warning in ¢ page 177,
before opening the hood and checking 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
could burn yourself. Let the engine cool off
firstsothatyoucannothearorseeany
steam or engine coolant .
(D Note
-Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheat ing during
high o utside temperatures and heavy en-
gine load.
- The front spoiler also helps to distr ibute
cooling air correctly wh ile driving .
If the
spo ile r i s damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase . See an a uthorized
Audi dealer or authorized Audi Service Fa­
cility for assistance .
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
You shou ld sh ift to the next lowest gear when
the eng ine speed is be low 1 500 RPM. The beg in­
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 temperature. Before reaching this zone, you should sh ift into
the next highest gear , select the D selector lever
position, or remove your foot from the accelera­
tor pedal.
CT) Note
The needle in the tachometer@¢ page 10,
fig . 3
may only be in the red area of the gauge
for a short time or the re is a r isk of engine
damage. The locat ion where the red zone be­
gins varies depend ing on the engine.

Fuel level
The fue l level indicator on ly operates when the
ignition is sw itched on . The

turns on if the reserve quantity of fuel is reached .
For the tank capacity in your veh icle, refer to the
Techn ica l Data ¢
page 230.
(D Note
Never drive until the tank is comp letely emp­
ty. The irregu lar supply of fuel that res ults
from that can cause the engine to m isf ire.
Non-combusted fuel will then enter the ex­
haust system . This can cause overheat ing and
damage to the catalyt ic converter.
Indicator lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
funct ions¢ .&..
With some indicator lights, messages may ap­ pear and warning signals may sound. The indica­

& WARNING
-Never open the hood if you can see or he ar
steam or coolant escaping from the engine
compartment. This inc reases t he risk of
burns . Wa it until you no longe r see or hea r
steam o r coolant escap ing .
- The engine compartment in any veh icle can
be a dangerous area. Stop the eng ine and
allow it to coo l before working in t he engine
compartment . A lways fo llow the informa­
ti on foun d in ¢

Do not contin ue d riving if the. indicator
light turns o n -thi s increases the r isk of en­
gi ne damage.
"t!:r. 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
v e re damage to the engine .
• Turn off engine! Oil pressure is too low.

do not continue driving . See you r auth orized
Audi dealer or qualif ied repa ir facility.
@ 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, preferably
each time you refuel, and always before
going on a long trip.

On-Board Diagnostics
F ig. 16 Locat ion of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Eac h monitored
component in your engine system has been as­
signed a code. In case of a ma lfunction, the com­
ponent w ill be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
I f the light ill uminates after a refueling, stop the
veh icle and make sure the fuel filler cap is prop­
erly closed (on ly vehicles with gasol ine engine)

I n order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD).
I n order to connect the specia l diagnostic equip­
ment, push the plug into the Data Link Connector
(D LC). The DLC is located to the right of the hood

Your author ized Audi dealer or qualified work­
shop can interpre t the code and perform the nec­
essary repair .
.&_ WARNING
-
Do not use the diagnostic connector for pe r­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
Electronic speed Limiter
Your vehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum speed
26
of your veh icle. To reduce the risk of sudden tire
failure and loss of contro l if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
limiter prevents your vehicle from going faster
than the tire speed rating . For more information
r::!> page 191.
If the engine control un it receives faulty vehicle
road speed signals, the Malfunct ion Indicator
Lamp (MIL)
(,ij will illuminate. If this occurs,
contact the nearest author ized Audi dealer for
assistance.
.&_ WARNING
A lways observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
f ic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the t i res installed .
