Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometre s):
.,. Do not use full throttle .
.,. Do not drive at engine speeds that are more
than 2/3 of the max imimum permitted
RPM .
.,. Avoid high engine speeds.
From 600 to 1,000 miles (1 ,000 to
1,500 kilometres):
.. Speeds can gradually be increased to the
maximum pe rm iss ib le road or eng ine speed .
During and after break-in period
.. Do not rev the engine up to high speeds
when it is cold . T hi s applies whether the
transmission is in N (Neutral) o r in gear.
After the break- in period
.. Do not exceed max imum eng ine speed un­
der any circumstances .
.. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
<::;> page 10.
During the first few hours of driving, the en­
g ine 's inter na l friction is higher than later
when all the moving pa rts have been broken
i n. How well this break-in p rocess is done de­
pends to a considerable ex tent on the way t he
ve hicl e is driven d uring the first 1,000 miles
(1, 500 kilome tres) .
(D Note
Extremely high engine speeds a re auto­
mat ic al ly reduced. However, t hese RPM-
Driving and environment 149
limits were programmed for an eng ine
well run-in, not a new eng ine.
@ For the sake of the environment
Do not d rive wi th unnecessar ily h igh en­
gine speeds -upshifting ear ly saves f uel,
r educes noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly carefu l for the first 350 miles
(500 ki lometres) after fitting .
A WARNING
-New tires tend to be s lippery and must a l-
so be "b roken-in". Be s ure to remembe r
this dur ing t he firs t 35 0 m iles (500 kilo­
me tres) . Brake gent ly . Avo id following
closely behind other vehicles or other sit­ uations that m ight require sudden, hard
b raking.
New brake pads
Remember that new brake pads do not have a
full brak ing effect during the first 250 miles
(400 kilometres) after they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&..
D uring the break-in period, yo u should avoid
putting seve re loads on the brakes . Severe
l oads include, for example, su dden hard brak­
ing, in particular at very h igh speeds or, for
example, on mou nta in passes.
A WARNING
Until t hey develop the maximum "bite" fo r
best stopping power, the s urfaces on new
b rake pads requ ire some "brea king- in" dur­
in g the initial 10 0 to 150 miles (15 0 to
20 0 kilome tres) of normal c ity dr iv ing. Yo u
can compensate for this by press ing the
b rake peda l more f irm ly . This applies
whenever new pads are installed.

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 ..,.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not continue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Warranty
&
Ma intenan ce booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Shutting down vehicle
If you would like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized deale r. T hey can ad­
vise you on necessary precautions e.g . corro­
sion prevention, ma intenance and storage.
Pay attention to add itiona l information con­
cerning the battery . Re fer to~

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your eng ine, brakes and tires largely
depend on three factors:
- your personal d riving s tyle
- operati ng conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut you r
fuel consumpt io n by 1O-lS percent . T his sec­
tion w ill give you some tips on how you can
help the env ironment and your po cketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROT ECTI ON AGENCY
( E PA) a nd Tra nsp o rt Canada may no t corre­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary acce lerating and braking .
Vehicles use the most f ue l when they are ac­
ce le rat ing. If you ant icipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less . Let the vehicle coast
whenever possible - for examp le when you see
that the next traff ic light is red.

& WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents.
- To reduce the risk of cuts, protect your­
self from sharp meta l components when
washing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be delayed due to moisture on
the brake rotors or ice in the winter . The
brakes must be dried first with a few
careful brake applicat ions .
{[) Note
-If you wash the vehicle in an automatic
car wash, you must retract the extend a­ ble rear spo iler* if necessary, and fold
the exte rior m irrors in to reduce the risk
of damage. Power folding exterior mir­ rors* must only be folded in and out us­
i ng the power folding function .
- To prevent pa int damage, do not wash
the veh icle in direct sunlight.
- To reduce the risk of damage, do not
wash the power top with a p ressure
washer. -
To reduce the r isk of damage, do not
wash decorative decals * with a pressure
washer.
- To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply
protective wax.
It can destroy the
matte fi nish effect.
- Do not place any stickers o r magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint cou ld be
damaged when the stickers o r magnets
are removed.
@ For the sake of the environment

-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. Wa it 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
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:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
Checking and filling 165
- 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 wear no clothing that will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&. .

Checking brake fluid level
Fig . 133 Engine compa rtment: cove r on the brake fluid
reservo ir
Before you check anything in the engine com­
partment,
a lw ays read and h eed all WA RN­
ING S ¢&. in Working in the engine compart ­
ment on page 164.
,.. Read the brake fluid level from the brake
fluid reservoir¢
page 166, fig . 128. T he
brake flu id leve l must be between the "MIN"
and "MAX" markings.
The brake flu id rese rvo ir is located behind the
rear part ition of the eng ine compartment o n
the left side ¢
page 166.
The fluid level may drop slightly after some
time due to the automatic adjustment of the b rake pads . This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U.S. models: . , Canadian mod­
e ls: . ) w ill come on
¢page 14. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized A udi dealer or other quali­
fied facility and the cause corrected.
If the
brake fluid level is too low, the brake warn ing/
indicator light w ill illuminate. Contact an au­
thor ized Audi dealer
imm ediatel y.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
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
after a period of time . The boiling point of the
brake flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
eve ry two y ears. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "F MVSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer . Your dealer has the correct
tools, the right brake fl uid and the know -how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake flu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
specifica tion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 1 16.
Always check with yo ur authorized Aud i
dealer to make sure yo u are using the
correct brake fluid. The correct type of brake f lu id is also ind icated on the
brake flu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong. This can seriously affect the effi­
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

@ 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.
