~ Malfunction Indicator Lamp (MIL)
T he Ma lfunction Indi cato r Lamp ( MIL) is pa rt
of the On-Board Diagnos tic (OBD II) system .
T he symbo l
fl lights up when the ign ition is
turned on and will turn off after the eng ine
has started and has settled at constant id le
speed . This indicates that the MIL is work ing
properly.
T he warning lig ht ill uminates when there is a
malfunction in the engine electronic system .
Contact your a uthori zed Aud i dea ler and have
the malfunction corrected.
An improperly clo sed fuel filler cap may al so

Ma ximum 6000 RPM
T he eng ine speed is automatically limited to
6 000 RP M. T his pro tects the engine fr om

T he eng ine speed limitation

once the eng ine is no longe r in t he cr itica l

acce le rator pedal once.
(D Tips
When co ld, the engine speed is l imited to
6000 R PM (w ith the
VlO engine) or
7000 R PM (with the VB engine) to p rotect
the engine. The limit is deactivated once
the oil temperature r ises above 140 °F
(60 °C) and the engine is at operating tem­
perature .

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru. Be sure to
switch ESC on again when you no longer need
less traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking . Apply steady pres ­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to
normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot overcome
th e laws of physics. This is especially im ­
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve­
hicle, you should immediately change
yo ur speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligent technology 145
to take risks. Doing so will increase the
risk of a lo ss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot prevent colli­
sions.
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire si zes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working.
- If the ind icator lightD] orE (USA
models)/ [iJ (Canada models) appears,
there may be a malfunction¢

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sea led and generally re­
q ui res lit tle at ten tion.
The cooling system has been filled at the fac­
tory with a pe rma nent coolant which does not
need to be changed. The coolant consists of a
mix ture o f wa ter and the m anu fa ctu rer 's g ly ­
col -based coolant addit ive Gl3 antifreeze
with anticorrosion additives (50% for USA mod els; 60% for Canadian models) . This mix ­
ture both assures the necessary frost protec ­
tion and protects metal components i n the
engine's cooling system from corrosion and
scaling .
It also raises the bo iling po int of the
coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant addit ive must b e at
lea st 50% but not more than 60 %
to main­
tain antifree ze protection and cooling efficie n­
cy.
If t he cool ant frost pro tect io n is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and engine cooling system.
Checkin g and fillin g 181
For year -round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( -40 °C) Canada.

CD Note
- Before wi nte r sets in, have the coo lant
checke d to see if the cool ant a ddi tive in
yo ur vehicle is sufficient to meet the cli ­
mate conditions . This is especia lly impor ­
tant if you live in a region where the win­
ter is extreme ly cold. I f necessary, in­
crease the proportion of coo lant add itive
to 60% .
- When adding coolant additive to your cooling system, remember :
- We re commend using o nly coola nt ad­
di tive G l2++ or Gl3 (check the l abe l)
for your vehi cle. This coolan t additive is
ava ila ble at autho rize d Aud i dea le rs .
Othe r ty pes of antifreeze can sig nifi­
cantly reduce corros ion protection. The
resu lting corrosion can cause a loss of
coolant and serio us engine damage.
- Do not add any type of rad iator leak seal ­
ant to yo ur vehicle 's engine coolant.

182 Checking and filling
Checking the engine coolant level
Proceed carefully when checking the coolant.

Fig. 145 Convert ible top sto rage bay: coo lant expan­
sion tank
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS c:::> &_ in Working in the engine compart­
ment on page 173
and park your vehicle on a
level surface.
The coolant expansion tank is located in the
right side of the convertible top storage bay
under the round metal cover
c:::> fig. 145. The
convertible top must be in the service position
to check the coolant leve l
c:::> fig. 144.
Bringing the closed convertible top into
the service position
.. Switch the ignition on .
.. Pull and hold the convertible top switch .
.. Press and hold the rear window switch too
until the convertib le top moves into the
service position
c:::> fig. 144.
Bringing the open convertible to into the
service position
.. Switch the ignition on.
.. Press and hold the convertible top switch. ..
Press and hold the rear window switch too
until the convertible top moves into the
service position
c:::> fig. 144.
Opening the coolant expansion tank cover
.. Stop the engine and allow it to cool.
.. Switch the ignition off .
.. Care fully remove the bolts in the cover@
using a screwdriver and remove the cover.
The coolant reservoir is located below
¢fig. 145.
Checking the engine coolant level
.. Place a rag or cloth on the cap of the coolant
expansion tank and turn the cap
carefully to
the left (counter-clockwise)
c:::> .&, .
.. Read the coolant leve l inside the coolant ex­
pansion tank¢
fig. 145. With a cold engine,
it must be above the "min" mark. With a hot
eng ine, it can be a little above the indicated
range.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped
with an electric coo lant level sensor
c:::> page 15. We still recommend you check the
coolant level from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
In a
sealed system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a result of overheating .
A WARNING
-- The cooling system is under pressure. Do

- The coolant additive, and therefore the
coo lant itself, is haza rdous to hea lth .
Keep the coolant additive in the original
