198 Driving and the environment
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water or mud, the
braking effect can be reduced due to mois
ture on the brake discs and brake pads. A
few careful brake applications should dry off the brakes.
@) Note
Vehicle components such as the engine, transmiss ion, suspension or electrical sys
tem can be severely damaged by driving
through water.
- Determ ine the depth before driving
through water.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water .
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi
cle to drive through safely.
- Avoid dr iving through salt water (corro
s ion).
Catalytic converter
App lies to vehicles: with gasoline engine
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner.
> Always use lead-free gaso line r=;, page 210,
Fuel supply .
> Never run the tank down all the way to emp-
ty.
> Never put too much motor o il in your engine
r=;, page 223, Adding engine oil
The catalytic converter is an efficient "clean
up" device built into the exhaust system of
the vehicle . The cata lytic converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critica lly
important for the life of the catalytic convert
er and proper functioning of the engine.
A WARNING
-
The temperature of the exhaust system is high, both when driv ing and after stopping
the eng ine .
- Never touch the exhaust tail pipes once
they have become hot . This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust manifold, exhaust pipes, catalytic con
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously de
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
r=;, page 223.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherwise fuel

@ Tips
- The oil pre ssure wa rning display. i s
not an indicator of the o il level. Do not
rely on it. Instead , chec k the oil le vel in
your engine at regular inter vals, pref
era bly each t ime you r efuel , and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oi l, we
r ecommend that you consult an author
iz ed Audi dealer to have the cause of
you r concern properly di ag nose d. Keep in
mind tha t the ac curate measuremen t of
oi l consumption requires great care and
may take some time. An authorized Audi
dealer has instructions about how to measure oil consumption accurately.

The oil consumptio n of the engine may be up
to 1/2 q uart per 600 m iles (0.5 liter per
1,000 km), depend ing on d riving style and
cond it io ns. Consump tion may be higher du r
ing the first 3,000 m iles (5,000 km) . Be ca u se
of this, the eng ine oi l level must be checked
regular ly . It would be best to check each time
you ref uel your vehicle and before long dr ives.

Always keep your forearm parallel to the
ground to help prevent hot oil from run
ning down your arm.
- Drain the oi l into a conta iner designed
for this p urpose, one large eno ugh to
hold at least the total amount of oil in
your engi ne.
- Engine oil is poisono us. Keep it well out
of the reach of c hildren .
- Cont inuo us contact with used engine oil
is harmful to your skin. Always protect
you r sk in by washing oil off thoroug hly
with soap and water .
(D Note
Never mix oil addit ives with your engine
oil. These additives can damage your en
gine and adversely affect y our Aud i Limit
ed New Vehicle Wa rra nty .
@ For the sake of the environment
- Before changing your oi l, f irst make sure
you know whe re you can proper ly dispose
of the used o il.
- Always d ispose of used engine oil proper

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 an d generally re
q uir es little attention.
The cooling system has been filled at the f ac
tory with a pe rm anen t coo lan t which does no t
n eed to be changed. The coolant consists of a
mixture of specia lly conditioned water and the
manufacturer's glyco l-based coo lant add i-
tive Gl3 antifree ze with ant icorros ion addi-
Checking and Fillin g 225
tives (50% for USA mode ls; 60% fo r Canadian
models) . This mixture both ass ures the neces
sary frost protection and protects metal com
ponents in the eng ine's cooling system from
corros io n and scaling. It also raises the bo il
ing point of the coolant .
Do not reduce the concentration of the cool
ant in the s ummer by adding p lain water.
The
proportion of coolant additive must be at
least 50°/o but not more than 60 %
to main
ta in antifreeze protect io n and cool ing eff ic ien
cy . If the coo lant frost p rotection is too low ,
t he coo lan t could freeze and damage the vehi
cl e heating and engine cooling sys tem.
Fo r year- round drivi ng, a ntifreeze is added at
the factory fo r temperatures down to:
- -31 °F
< -3s0c) u sA
- -40°F ( - 40°C) Canada.
If you must ad d coo lant, use a mixture o f wa
te r and coolant additive. Mixing the coo lant
additive with dist illed water is recommended.
A WARNING
Before you chec k anything in the engine
compartment, always read and heed all
WARNI NGS
c:> page 217.
-
(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli mate condit ions. This is especially impor
t ant if you l ive i n a region where the win-
t er is extremely cold. If necessary, in-
c rea se t he p ropo rtion of coo lant add itive
t o 6 0% .
- Whe n ad d ing coolant addi tiv e to yo ur
c ooling sys te m , reme mbe r:
- We recommend using on ly coo lant ad
d itive Gl2 ++ or Gl3 (check the labe l)
for your vehicle. This coolant additive is ava ila ble at autho rized Aud i dea le rs .
Othe r ty pes of antifreeze ca n sig nifi
cantly reduce cor ros io n protec tion . The

226 Checking and Fill in g
- Do not add any type of radiator leak sea l
ant to your ve hicle's engine coolant.
Adding rad iator 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.

ant expans ion tank
R ea d a nd f ollow ing th e W ARNING S before
checking anything in the eng ine compartment
¢ page 217.
Ch eck ing t he e ngi ne coolant level
"Park your vehicle on a level surface .
.. Switch the ign ition off .
" Read the coo lant level on the coolant expan
s ion tank ¢
fig. 164. The coo lant level must
be between the markings when the eng ine
in cold. When the engine is warm it can be
sl ightly above the upper marking .
Adding coolan t
Requirement : There must be a residual
amount of coolant in the expansion tank ¢(D .
.. Let the engine cool down.
" Place a cloth over the coolant expansion
tank cap and unscrew the cap counterclock
wise ¢&_ .
.. Add coolant mixed in the correct ratio
¢ page 225 up to the upper marking.
.. Make sure that the fluid level remains sta
ble. Add more coolant if necessary.
" Clove the cap securely. A coolant loss suggests a
leak. Immediately
drive your vehicle to an authorized repair fa
c ility and have the cooling system inspected.
If the cooling system is not leaking, a loss can
come from the coolant boiling through over
heating and being pushed out of the cooling
system.
A WARNING
The cooling system is press urized and can
become very hot. To reduce the r isk of
b urns from hot coolant:
- Do not open the coolant expansion tank
cap with the engine ho t. T here is a risk of
burns.
- Stop the eng ine and a llow it to cool.
- Protect your face, hands and arms from
escaping coolant and steam by covering
the coolant tan k cap with a large, th ick
cloth.
- Turn the coolan t tank cap counterclock
wise slowly and keep light pressure on
the cap .
- To reduce the risk of burns, do not allow
any antifreeze or coolant to drip onto the
exhaust system or hot engine compo
nents. The ethy lene g lycol in engine
coo lant can catch fire under certain cir
cumstances.
- The coolant additive and the coolant can
be dangerous to your health . For this
reason, keep the coo lant in the origina l
container away from ch ildren . There is a
risk of poisoning.
- When working in the engine compart
ment, remember that the rad iator fan
can switch on even if the ignition is
sw itched off, which increases the risk of
pe rsonal injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the eng ine .
If this is the case,
do no t continue dr iving. See a n author ized
