150 Driving and en vironm ent
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehi cle body.
- Do no t drive faster than wa lking speed.
_& WARNING
After d riving through water, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads . Dry
the brakes fi rst by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may c reate waves that raise the water
l evel and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.
-
Catalytic converter
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 gasoline¢ page 160,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much moto r o il in yo ur eng ine
¢ page 169, Adding engine oil ~-
.. Never try to push- or tow-st art you r vehicle.
The catalytic co nverter is an efficient "clean­
u p" dev ice built into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollutan ts in the exha ust gas be ­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert­
er and prope r funct ion ing of the engi ne.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry g rass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
r u stproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converte r.
- Do not exceed the correct engi ne oil level
¢page 169.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.

158 Vehicle care and cleaning
- Never remove snow or ice from win­
dows and mirrors using warm or hot
water because this could cause cracks to form .
- To avoid damage to the rear window
defogger, do not apply any stickers on
the heating wires on the inside of the
window.
- Decorative parts/trim

leaving the vehicle parked for long pe ­
riods of time, you should cover the
leather to protect it from direct sun­
light.
@ Tips
- Insects are easier to remove from paint
that has been freshly waxed.

168 Checking and filling
Detergent additives in the o il will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
M aintenance book let . Your dea ler will have to
deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in per iod (see
c::> page 149) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road cond it io ns. Furthe r fac­
tors are the amo unt of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tab lished or spec ified. There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instr ument cluster
1\1 lights up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::> page 169. Top off the
o il at your earliest conven ience
c::> page 169 .
A WARNING
-Before you chec k anything in the eng ine
compartment, a lways read and heed a ll
WAR NINGS
c::> .& in Working in the engine
comportment on page 164.
CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
rely on it . Instead, check the oil level in
your engine at r egular intervals, pr ef­
erably ea ch time you refuel, and alway s
before going on a long trip.
- If you have the impression yo ur engine
cons umes excessive amoun ts of oil, we
recommend that you consult your Aud i
dea ler to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requires great care and may
take some t ime . Your Audi dea ler has in­
st ruct ions about how to measure oil con­
sumption acc urately.

@ For the sake of the environment
Because of the problem of proper disposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
Your vehicle is equipped with a special bat­
tery, an
ACM battery. This battery is located
in the luggage compartment and must be re­
p laced w ith an original equipment battery .
Under normal operati ng conditions, the bat­
tery is
maint enan ce -fre e.
Have the battery checked when you take your
ve hicle in for service. You are well adv ised to
replace a battery that is older than
5 years.
Di sconn ect ing the battery terminal s
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are d isconnected. These functions have
to be re learned after the battery terminals are
connected again . To prevent this, the battery
should only be d isconnected from the vehicle
e lectr ica l system when absolutely necessary
for repairs .
Vehicles not driven for l ong period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo ­
nents are gradually cut back o r switched off .
This reduces energy consumption and main­
tains sta rting capab ility over a longer per iod
c::> page 146. Some of the convenience func­
tions may not operate, s uch as the interior
lights or power seat adjustment. The conven ­
ience functions will be avai lab le again when
you switch on the ignition and start the en­ g ine.
Winter operation
D uring the winter months, ba tte ry capaci ty
tends to decrease as temperatures d rop. This
is because more powe r is also consumed while
Checkin g and fillin g 175
starting, and the headlights, rear window de ­
fogger, etc ., are used more often .
Avoid unnecess ary powe r consumpt io n, p ar­
t icu lar ly in city traffic o r when traveling only
sho rt distances. Let your authorized A udi
dealer check the capacity of the vehicle bat­
tery before winter sets in
c::> page 178. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer .
Replacing battery
The new battery must ha ve the same capaci ­
ty, voltage (12 volts), amperage, construction
and plug sea ling, as the original battery. Spec­
ifications are listed o n the battery housing.
Batter ies spec ia lly developed by Audi fulfill
the maintenance, outp ut, and safety require­
ments.
When installing the battery, make sure the ig­ nition and a ll electrical consumers are switch ­
ed off
c::> (D .
We recommend that you use maintenance­
free or
cycle -res istant /leak-proof batter ies
accord ing to the standards TL 825 06 (from
Apr il 2008) and VW 7 50 73 (from Ap ril
2010).
Rep lacing the battery should be carried by a
qualified workshop. Please fo llow the instruc ­
tions on the battery cover.
