The illumination for the instrument cluster
lights up whenever you switch on the ignition
with the
vehicle headlights off. The gauges
are also illuminated when the lights are
turned on.
Engine oil temperature display
The engine oil temperature display Q page 10,
fig. 3
only operates with the ignition on. To
prevent engine damage, please observe the
following important points concerning the
temperature ranges.
Cold range
If the needle is at the bottom of the gauge,
the engine oil has not reached operating tem­ perature yet. Avoid high engine speeds, full
throttle applications and heavy engine loads .
Normal range
The engine has reached operating tempera­
ture when the needle moves into the center of
the gauge under normal driving conditions .
The needle may move higher on the gauge
with heavier engine load at high outside tem­ peratures. This is not a cause for concern as
long as the . indicator light in the display
does not flash.
Warning light.
If the symbol . in the display flashes, ei­
ther the engine oil temperature is too high or
the engine oil level is too low
Qpage 180.
If
the needle is well in the upper area of the
gauge, the engine oil temperature is too high .
Stop the vehicle, switch the engine off and
allow it to cool.
If the warning light comes on
again after driving a short distance, contact
an authorized Audi dealer.

12 Instruments and warning /indicator lights
If the needle is well on the right side of the
gauge, the coolant temperature is too high .
Stop the vehicle, switch the engine off and
allow it to cool.
If the warning light comes on
again after driving a short distance, contact
an author ized Audi dealer .
A WARNING
-Always observe the warni ng in
¢ page 175, Working in the engine
compartment before opening the engine
compartment lid an d checking the en­
gine coo lant level.
- Never open the engine compartment lid
if yo u see or hear steam, or if you see e n­
gine coolant dripping from the engine
compartment . You could burn yourse lf.
Let the engine coo l off first so that you
cannot hear or see any steam or engine
coolant.
(D Note
- Mounting additional lights or accessories
in front of the air inlets red uces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high engine load, the
engine could overheat .
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, th is could reduce the cooling
effect and the engine could then over­
heat. Ask you r autho rized Aud i dealer for
ass istan ce.
Fuel gauge
The fuel gauge works only when the ignition is
on. When the needle reaches the red area, the
warn ing light in the instrument cluster will il­
lum inate
c> page 33 (il This means you
have approximately 2.6 gallons (10 liters) of
fuel left in the tank .
Time to refuel!
The total tank capacity of your vehicle is listed
in
Technical data ¢ page 228.
(D Note
Never run the tank completely dry! An ir­
regular supply of fuel can cause engine
misfiring and fuel could enter into the ex ­
haust system . The catalytic converter
could then overheat and be damaged.
· Speedometer with odometer
The speedome ter shows you the vehicle
speed, and the odometer shows you how
many miles (kilometers) you have driven .
Fig. S Speedometer close -up: odome ter d isplay
The distance driven is shown in m iles (USA
models) or in kilometers (Canada mode ls).
Lower odometer
The lower odometer shows the total number
of miles (kilometers) dr iven .
Upper odometer (trip odometer)
The upper odometer shows the total number
of miles (kilometers) dr iven since you last re­
set the odometer back to zero . You can use
th is odometer when you want to keep track of
how many m iles (kilometers) yo u have driven
for a single trip or errand. The last dig it ind i­
cates 1/10 of a mile (100 meters) . Yo u can se t
the trip odometer back to zero by pressing the
I RESE T! button ¢ fig . 5 .
With the ign ition off, pushing of the Set/
Check button ¢ page 10, fig. 3 @ can turn on
the display field lighting for a few seconds.
Malfunction message
If there is a malfunct ion somewhere in the in-
strument cluster,
dEF will appea r in the trip .,.

16 Instrum ent s and w arn ing /indic ato r light s
If this warning/indicator light illuminates
while you are driving, then there is a mal ­
function in the engine electron ics. Have
the malfunction corrected as soon as pos­
sible by your authorized Aud i dealer or
qualified workshop .
"' Convertible top operation
The indicato r light turns on IJI
- When the convertible top opens or closes or
- If the convertible top d id not open or close
completely.
The indicator light blinks if the convertible top
cannot open or close¢
page 47.
n If; Electronic stabilization program
(ESP)
If the indicator lamp Gl blinks while dr iv ing,
the ESP or ASR (Ant i-Slip Regulation) is active­
l y regulating.
If the indicator lamp
Gl illuminates, the sys ­
tem has sw itched the ESP off . In this case , you
can switch the ignition off and then on to
switch the ESP on again . The system is func­
tioning comp letely when the indicator lamp
switches off .
If the indicator lamp
I] illuminates , the ESP
was sw itc hed off with the
lliJ button.
E S P and A BS: fa u lt ! See owner's manu al
If the indicator lamp Gl and the ABS indicator
lamp
!I] illuminate and the driver message
appears, the ABS or electronic differential lock is malfunctioning . This also interrupts the
ESP . The brakes st ill function with the ir nor­
mal power, but ABS is not active .
Drive to your authorized Aud i R8 dealer imme­
d iately to have the malfunction corrected.

& WARNING
=
Driving at higher speeds witho ut the rear
spoiler deployed can impair handling char­
acteristics, making the vehicle harder to
control.
- If the rear spo iler warning/ind icator light
in the instrument cluster comes on, the
rear spo iler may not have dep loyed. Nev ­
e r drive at speeds h igher than 87 mph
(140 km/h) if the spo iler is not deployed .
H ave the spoiler inspected as soon as
possible by an a uthorized Aud i dea le r or
qualified wor kshop.
¢ ¢Turn signals
Whenever yo u use the left II or the right R
turn signal, the indicator light blinks. When
you use the emergency flasher, both indicator
li ghts f lash.
If one of the turn signa l light bulbs burn out,
the turn signal will blink twice as fast as nor­
mal.

154 Intelligent technology
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving position . Do not
ride the brakes or hold the pedal down
too long or too often. This could cause
the brakes to get hot and diminish brak­ ing efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Cautiously apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few cau­
tious brake applications .
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
braking capability, resulting in increased
stopping distance. Avoid driving the vehi­
cle and have it towed to the nearest au­
thorized Audi dealer or qualified work­
shop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
example when towing your vehicle, or because the brake booster has somehow
been damaged, the brake pedal must be pressed considerably harder to make up
for the lack of booster assistance.
Power steering
When the engine is running , power steering
makes i t easier for the driver to steer.
Power steering helps the driver steer the vehi­
cle with little physical effort.
If the engine is not running, the power steer­
ing system is also not working . In this case ,
you will find it extremely difficult to turn the
steering wheel.
If you turn the steering fully to the left or
right when the vehicle is stationary, you place
a very heavy load on the power steering sys­
tem. Turning the steering wheel fully to the left or right will cause noise in the system. It
also reduces engine idle speed.
(D Note
Do not hold the steering turned fully to
the left or right for more than 10 seconds
when the engine is running . There is a risk
of damage to the power steering system .
(D Tips
-In the event of a power steering system
failure, or if the engine is not running
(while being towed), you will still be able
to steer the vehicle. However, you will re­
quire more effort to do so .
- If the power steering system has a leak
or is defective, you should immediately
contact a qualified workshop .
- The power steering system requires a
special hydraulic fluid. The power steer­
ing fluid reservoir is located in the en­
gine compartment. The correct hydraulic
fluid level is important for proper opera­
tion of the power steering system. The
power steering fluid level is checked ac­
cording to the Audi maintenance service
schedule.

will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If this driver notification appears after the ig­
nition is turned on or while driv ing and it goes
out again after a wh ile, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notification appears after the ig­
nition is turned on or while driv ing and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ability is
restricted. Have the battery checked as soon
as poss ible by an author ized Audi dealer or
qualified workshop.
Dry sump lubrication
H igh lateral and long itud inal forces affect the
engine and the vehicle during sporty driving.
Dr y sump l ubr ica tion ensures that your engine
i s supplied w ith oil and properly lub ricated
even under these conditions.
I n a "normal" veh icle the o il pump sends the
oil from the oil pan to the lubrication points in
the engine. The oil then returns to the oil pan .
I n extreme situations, the oil pump may draw
in air, which results in insufficient oil pressure.
With dry sump lubrication, the oil is not in the
oil pan (it is "d ry"), but in a separate oi l tank.
While one pump supplies the engine with oi l,
a second pump suctions the oi l out of the en­
g ine and returns it to the oil tank . Because the
oil tank is ta ll and narrow, o il pressure is con­
stant even under extreme conditions.
In addition, the oil pan in vehicles with dry
sump lubrication is noticeably sha llower. Th is
allows the engine to be installed lower in the
vehicle, bringing down the center of gravity .
This improves your vehicle's handling .
