& WARNING
-Always observe the warning in
¢ page 172, Working in the engine
compartment
before open ing the engine
compartment lid and checking the en­
gine coo lant level.
- Never open the engine compartment lid
if you see or hear steam, or if you see en­
gine coo lant dr ipping from the eng ine
compartment. You could bur n yourse lf.
Let the engine coo l
off first until you can
no longer see or hear steam or coolant
escaping .
CD Note
- Mounting additional lights or ac cesso ries
in front of the air inlets reduces the cool­
ing effect of the radiator . At high outside
temperatures or high engine load, the
engine could overheat.
- The front spoi ler has been designed to
proper ly distribute the cooling air when
the vehicle is moving. If the spoiler is
damaged, th is could reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Aud i dea le r fo r
ass istance.
Fuel gauge
The fuel ga uge works only when the ignition is
on. When the needle reaches the red area, the
warning light in the instrument cluster will i l­
luminate ¢

CD Note
Never run the tank completely d ry! An ir­
regular supply of fue l can cause engine
misfiring and fuel could enter into the ex­
haust system . The catalyt ic converter
co uld then overheat and be damaged. Speedometer with odometer
The
speedometer shows you the vehicle
speed, and the odometer shows you how
many miles (kilometers) you have driven.
1S3.9
miles S2YY
F ig . S Speedometer close-up: odometer display
The distance driven is shown in m iles (USA
models) or in kilometers (Canada mode ls) .
Lower odomet er
The lower odomete r shows the tota l number
of miles (kilometers) driven.
Upper odometer (trip odometer )
The upper odometer shows the total number of miles (kilometers) driven s ince you last re­
set the odometer back to zero. You can use
t hi s odometer when you want to keep track of
how many m iles (kilometers) yo u have driven
f o r a si ngle tr ip or e rrand. The last dig it ind i­
cates 1/10 of a mile (100 meters). Yo u can set
the trip odometer back to zero by pressing the reset button ¢
fig. 5.
With the ignit ion off, pushi ng of the Set/
Check button
~ page 8 , fig . 3 0 can turn on
the display fie ld 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
odometer and w ill s tay on. Co ntact your au ­
thorized Audi dea ler to have the prob lem cor­
rected .
Immobilizer
When the ignition is sw itched on, the data on
the ignition key are scanned automatic ally. .,..

WARNINGS. The engine compartment of any
vehicle is a hazardous area!
c::> &.
A WARNING
To help avoid injury, before you check any­
thing under the engine compartment lid:
- Switch off the engine.
- Remove the ignition key.
- Apply the parking brake.
- Move selector lever of S tronic to "N"
(Neutral); put manual transmission in
Neutral.
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the engine compartment lid if you
see or hear steam or coolant escaping
from the engine compartment. Wait un­
til no steam or coolant can be seen or heard before carefully opening the en­
gine compartment lid .
- Keep children away from the engine com­
partment .
-Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never open the coolant reservoir cap when the engine is still warm. The cool­ant 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
thick 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:
Checking and filling 173
- 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 of S tronic to "N"
(Neutral); put manual transmission in
Neutral.
- 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 wear no clothing that will hang or droop into the engine.
- Minimize exposure to emission and chemical hazards
c::> .&. .
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.
@ 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

container out of the reach of children. It
is a poison hazard.
@ Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Lim ited
Warranty.
Adding coolant
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS q A in Working in the engine compart­
ment on pag e 173.
"'Add coolant .
"'Twist the cap on again
tightly.
"'Tighten the cap (D q page 182, fig. 145
again.
Replacement engine coolant must conform to
exact specifications
q page 181, Coolant .
We recommend using only coolant additive
G12++, G13 or in an emergency G12 +. Do
not
use a different additive. In an emergency use
plain water until you can get the correct addi­
tive and can restore the correct ratio. This
should be done as soon as possible.
If you have lost a considerable amount of
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling .
Do not fill coolant above the "max" mark. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en­
gine becomes hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
Checking and filling 183
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire .
- Antifreeze is poisonous. Always store an ­
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison" .
Q) Note
- Coolant pollutes the environment and
could cause an engine fire . Ex cess cool­
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze
q page 181 must be re­
stored as soon as possible.
@ For the sake of the environment
Drained coolant should not be reused . Al­
ways dispose of used coolant while observ­
ing all environmental regulations.
Brake fluid
Have the brake fluid changed by an experi­
enced t echnician.
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
afte r a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance. .,.. •
