Brake lining w ear sta tus
Brake lining we ar may be che cked by visual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the wheel may be remove d for this in­
spection
c> page 244, Changing a wheel.
.&_ WARNING
- New brake pads do n't have the best sto p­
ping power and must be "broken-in" dur­
ing the init ial 100 to 1 50 m iles (150 to
200 k ilometers) of normal city driving.
T he break-in period can be considerably
longer for veh icles with ceram ic br ake ro­
tors*. You can compensate for this by pressing the brake pedal more firmly.
T his also applies later when new pads are
installed .
- You should perform braking maneuvers
for the purpose of cleaning the brake
system on ly if road condit ions permit.
Other road users must not be put at r isk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too ofte n. This cou ld cause the
brakes to get hot and d imin ish b raking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not inte nd
t o brake. Th is may cause the b rakes to
overheat, prema ture wear and inc reased
stopping distance .
- Under certa in climat ic and operating
conditions such as passing through wa ­
ter, driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­ ings will be cleaned off after a few ca re­
ful brake applications.
- Driv ing fo r an extended pe riod of time on
salt-covered roads w ithout using you r
Intellig ent technolog y 175
brakes can a lso affect braking efficiency .
Clean off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler , be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brake system could
overheat reducing t he effectiveness of
the entire brake system.
- Failure of one b rake circuit will impa ir
the braking capab ility result ing in an in­
creased s topping distance. Avoid driving
the vehicle and have it towed to the near­
est a utho rized Audi dea le r or q ualified
workshop.
- Never let the vehi cle roll to a stop with
the engine shut off.
- If the b ra ke booste r is no t working, the
brake peda l must be p ressed considera­
b ly harder to make up for the lack of
booster assistance .

power seat adjustment. The convenience
functions will be ava ilable again when you
switch on the ignit ion and start the engine.
With th e engine turn ed off
If yo u listen to the radio, for example, with
the engine turned off or use other MMI fu nc­
tions, the battery is being discharged .
I f sta rting capabi lity is jeopa rdized due to en ­
e rgy consumpt ion, the fo llowing warning ap­
pears in the MMI display:
Please start the eng ine soon or th e syste m
will be turned off .
The warning ind icates that the system will be
turned off automatically after 3 m inutes. If
you wish to con tinue us ing t he functions, you
have to s tart the engi ne.
With the engine running
A lthough electrical energy is generated when
the veh icle is be ing dr iven, the battery can be­
come discharged . T his happens most ly when
little energy is be ing generated a nd a great
deal consumed and the battery 's state o f
charge is no t optima l.
To br ing the energy balance back into equili­
b rium, consumers which require especially
l arge amo unts of energy are tempo rari ly cut
back or switched off. Heating sys tems in par­
ticular require a great dea l of energy . If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy ba lance has been restored.
You will a lso notice that engine idle speed has
been increased slightly. This is norma l and not
a cause for concern . By increasing engine idle
speed the add itiona l energy required is gener­
ated and the batte ry is charged .

182 Driving and en vironm ent
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage .
"'Try and keep well below your car 's max imum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
g ine no ise increase d isproportionately at high
speeds. If you dr ive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never dr ive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
"'Shut the engine off when you are not dr iv ing
the vehicle .
"'Do not warm up the veh icle by letting the
engine run at idle .
It makes sense to shut
off the e ngine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings , or at traff ic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
bu rned s tarting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . Howeve r, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
([) Note
Do not leave engine idling unattended af ­
ter starti ng . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over- heating o
r othe r damage to the ve hicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"' Have your ve hicle serviced at reg ular in ter -
vals.
By having your veh icle regu la rly serviced by an
a utho rized Aud i dea le r helps to ensure that it
runs properly and econom ic all y. The cond it ion
of your veh icle not on ly affe cts its safety and
ability to ho ld its va lue, it a lso affects
fuel
con sumption .
Check your oil ea ch time you fill your tank.
The amount of o il used is re lated to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l cons umption and en­
gine output.
(D Note
- Have your vehicle maintained proper ly
and in accordance with the service rec ­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alte r or remove any device, such
a s hea t sh ie lds, swi tches, ig nitio n w ires,
valves, which are designe d to p rotec t
your vehicle's Emission Control System
and other impo rtant vehicle compo­
nents .

198 Checking and filling
Using the proper engine oil is important for
the functionality and service life of the en­
gine. Your engine was factory-filled with a
high-quality oil which can usually be used
throughout the entire year.
0 Note
Your Limited New Vehicle Warranty does
not cover damage or malfunctions due to
failure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet.
- Use only a high quality engine oil that ex­
pressly complies with the Audi oil quality
standard specified for your vehicle's en­
gine . Using any other oil can cause seri­
ous engine damage.
- Do not mix any lubricants or other addi­
tives into the engine oil. Doing so can
cause engine damage.
If you need to add oil and there is none
available that meets the Audi oil quality
standard your engine requires, you may
add a total of no more than 0.5 quart/liter
of a high-quality "synthetic"oil that meets
the following specifications.
- Vehicles with gasoline engine: ACEA A3
or API SM with a viscosity grade of
SAE 0W-30, SAE SW-30 or SAE SW-40.
- For more information about engine oil
that has been approved for your vehicle, please contact either your authorized
Audi dealer or Audi Customer Relations
at 1 (800) 822-2834 or visit our web site
at www.audiusa .com or
www .audicanada .ca .
Engine oil consumption
The engine in your vehicle depends on an ade ­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cooling of internal engine components, all in­
ternal combustion engines consume a certain amount of oil. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see
¢ page 179) consume more oil during the
break -in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions . Further fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump­
tion may increase over time until replacement of worn components may become necessary.
With all these variables coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev­ el, see
Note.
If
the yellow engine oil level warning symbol
El in the instrument cluster lights up, you
should check the oil level as soon as possible
¢ page 199. Top off the oil at your earliest
convenience
¢ page 199.
A WARNING
--
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
& in Working in the engine
compartment on page 195.
{(D Note
Driving with an insufficient oil level is like­
ly to cause severe damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­ erably each time you refuel, and always
before going on a long trip. .,.

Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by an authorized
Aud i dealer or qualified workshop . The elec­
trolyte leve l should also be checked each time
the battery is charged c>
page 207.
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 yea rs .
W ith certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec­
tr ica l system for safety reasons c>

Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators, for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this, the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods

problems w hen the weather is cold, but w ill
also last longer.
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freeze . This will
p revent it from be ing damaged and having
to be repla ced.
Working on the battery

injury , acc ident and even fire. Read and
heed the following WARNINGS:
-Always wear eye protection. Do not let battery acid or any lead part icles get on
your sk in or cloth ing . Sh ield your eyes .
Explosive gases can cause blindness or
other injury .
- Battery acid contains sulfur ic acid . Sulfu­
ric acid can cause blindness and severe
burns.
- Always wear gloves and eye protection.
Do not tilt the battery because ac id
could leak out of the vent ilation open­
ings.
- If you get battery acid in yo ur eyes or
on your sk in, immediately rinse with
cold water for severa l minutes and get
medical attention .
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg -
ative cab les.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
wh ich could lead to damage or explosion
and personal injury.
-
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negat ive ground ca­
ble.
- Before performing any work on the e lec­
trica l system, switch off the engine and
ignit ion as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected .
If you are just go­
ing to replace a light bulb, then it is
enough to swi tc h off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you wi ll set off the alarm.
- When disconnecting the battery, f irst
d isconnect the negat ive cab le and then
the posit ive c ab le.
- Before reconnecting the batte ry, ma ke
sure all e lectr ica l consumers are sw itch­
ed off. Re connect the pos it ive cable first
and then the negative cable. Never inter ­
change the cables - this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could exp lode! If a battery has
frozen, then it must be replaced . A dis­
charged battery can freeze over at 32°F
(QOC).
- Make sure the vent hose is always attach­
ed to the opening on the s ide of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways rep lace a damaged battery.
