too high, or the coolant level is too low
¢ page 32.
If the needle is well in the upper area of the
ga uge , the coolant temperature is too high.
Stop the vehicle , switch the eng ine off and
allow the engine to cool.
If the warning light
comes on again after driving a short distance,
contact an authorized dealer.
A WARNING
- Always observe the warning in
¢
page 257, 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 bu rn yourself. Let the engine
cool off first until you can no longer see
or hear steam or coolant escaping.
0 Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high eng ine 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, this cou ld reduce the cooling
effect and the engine could then over­ heat. Ask your authorized Audi dealer for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer @¢ page 10, fig. 3 is the left
of the two large clock-type displays.
The engine turns at a speed 1,000
times the
single digit in the display, e.g . if the needle is
pointing at the "2" the engine is turning at
2,000 RPM.
If engine RPM drops be low 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod. Before reaching this area , move these­
lector lever to position D (Drive) or ease your
foot off the accelerator pedal.
(D Note
The tachometer needle should not move
into the red range. If it does, then only for
a very short per iod of t i me. You could
damage your engine by driving at high RPM .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .
Digital clock with date display

- Dr iving with low brake flu id is a safety
hazard . Stop the car and get professiona l
assis tance .
- If the ~ (USA models) . (Canada
models) brake system ind icator light
turns on toget he r with the ABS and ESC
i n dicator lights, the A BS/ ESC regulat ing
fu nction may have failed. Func tio ns that
s tabilize the vehicle a re no longer av aila­
b le. This could ca use the vehicle to
swerve and inc rease the r isk of s liding.
Drive carefully to the nearest authorized
Aud i dealer or other q ualified workshop
and have the ma lfu nction corrected .
-L Engine cooling system malfunction
A malfunction in the engine cooling system
must be repaired as soon as possible .
When the. symbo l in t he display blinks,
t h en eit her the engine coo la nt
temperature is
too high, o r the coo lant
level is too low. An
additional driver message can also be dis­
played by pressing the
I CHECK ! button:
Switch off engine and check coolant level
> Pull off t he road.
> Stop the vehicle.
> Tur noff the engine .

> Add coo lant if necessary ¢ page 266.
> Continue dr iv ing on ly after the engine cool­
ant warning/ind icator light goes out.
> Contact your authorized Aud i dealer for as -
sistance if necessa ry.
If the engine coolant level is correct, then the
radiator fa n may be the cause of the malfunc­
t ion .
If the . warning symbo l (a lternator mal­
funct ion) also lights up on the instrument
panel ¢
page 31, then the fan be lt may be
damaged .

-The brake booster and servotronic only
work when the engine is running. With
the ignition turned off, you have to apply
more force when steering or braking.
S ince you cannot steer and stop normal­
ly, this can lead to accidents and ser ious
injuries.
- The rad iator fan can continue to run for
up to 10 min utes even after you have
turned off the engine and removed the ign ition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build -up in the engine compartment.
«I) Note
Do not stop the engine immed iate ly after
hard or extended dr iving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up .

258 Checking and filling
-Apply the parking brake.
- Move selector lever to P (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
th ick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running: -
First, fully apply the parking brake,
move selector lever to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and chemical hazards

A WARNING
=
California Proposition 65 Warning:
- Engine exhaust, some of its constituents, and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition,
certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age to vehicle systems will occur.
@) For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other vehicle flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer.

For year-round driv ing, antifreeze is added at
the factory for temperatures down to:
- - 31 °F (- 35 °C) USA
- - 40 °F ( - 40 °C) Canada .
If you mus t add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distilled water is recommended .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 257.
(D Note
-Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely cold.
If necessary, in­
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive Gl2++ or G13 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection . The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in damage not covered by your New Vehicle
Limited Warranty.
