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
t h roughout the entire year.
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 SA E SW-40.
- Vehicles with diesel engine: ACEA C3 or
API CF with a viscosity grade of
SAE 0W-30 or SAE SW-30.
- For more information about engine oil
that has been approved for your vehicle, please contact either your authori zed
Audi dealer or Audi Customer Relations
at 1 (800) 822 -2834 or visit our web site
at www.audiusa.com or
www.audicanada .ca.
Checking and filling 225
Engine oil consumption
T he 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 effec tive 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
c::> page 200) consume more oil during the
break-in period than they consume after oil
consumption has stabili zed.
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 condi tions. 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
in the instrument cluster
II lights up, you
should check the oil level as soon as possible
c::> page 226. Top off the oil at your earliest
convenience
c::> page 226.
A WARNING
--
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c::> & in Working in the engine
compartment on page 222.
(D Note
Driving with an insufficient oil level is like-
ly to cause severe damage to the engine. .,.

232 Checking and filling
@ For the sake of the environment
Because of the problem of proper disposal
of brake fluid as we ll as the special tools
required and the necessary expertise, we recommend that you have the brake fluid
changed by your author ized Audi dealer.
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 drives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level should also be
checked each time the battery is charged
¢ page 234.
Have the battery checked when you take your
vehicle in for service . You are well adv ised to
replace a battery that is older than 5 years .
With certain types of airbag deployment, the battery is disconnected from the vehicle elec­
tr ical system for safety reasons¢
& in Re­
pair, care and disposal of the airbags on
page 161.
Disconnecting the battery terminals
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are disconnected. These functions have
to be relearned after the battery terminals are
connected again. To prevent this , the battery
should only be disconnected from the vehicle
e lectrica l system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capabi lity over a longer period
¢page 198. Some of the convenience func­
tions may not operate, such as the interior
lights or power seat adjustment. The conven- ience
functions will be available again when
you switch on the ignition and start the en­ gine.
Winter operation
During the winter months, battery capac ity
tends to decrease as temperatures drop. This
is because more power is a lso consumed whi le
starting, and the headlights, rear window de­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticu larly in city traffic or when traveling only
short distances. Let your authorized Audi
deale r check the capacity of the vehicle bat ­
tery before winter sets in¢
page 234 . A well
charged battery will no t only prevent star ting
problems when the weather is cold, but will
also last longer .
@ Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery shou ld be removed and
stored where it w ill not freeze. This will
prevent it from be ing damaged and having
to be replaced .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check any­
thing in the luggage compartment,
read and
heed all WARNINGS
¢ .&, .
Always heed the safety warnings , when work­
ing on the vehicle battery or the vehicle elec­
t rical system to prevent injury.
The following WARNINGS are very
important when working on the battery:
Always heed the following WARNING SYM-
BOLS and safety precautions when working
on the battery.

- Do not smoke.
- Do not interchange the positive and neg-
ative cab les.
- When working on the battery, be sure
not to short-c ircuit 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 in ju ry.
Checkin g and fillin g
-When a battery is charged, it produces
hyd rogen gas which is explos ive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the elect rical sys ­
tem, disconnect the negative ground ca­ ble.
- Before performing any work on the e lec­
trical system, switch off the eng ine and
ignit ion as well as any electrical equip­
ment . The negative cable on the battery
must be disconnected. If yo u are just go­
ing to replace a light bulb, then it is
enough to switc h off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you wi ll set off the al arm.
- When disconnecting the battery, first
discon nect the negat ive cab le and then
the posit ive cab 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. Neve r in ter ­
change the cables - this could start a fire!
- Never cha rge 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
(0 oc).

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb . Thi s appl ies especial ly to the light bu lbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb ho lders can have sharp
edges that can cause ser ious cuts, and parts
must be co rrectly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly resealed.
F or your safety, we recommend that you have
your author ized Audi dealer rep lace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas di scharge lamps (Xenon lights):
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Head lights w ith Xenon light can be identified
by the high voltage sticker .
LED headlights* require no maintenance .
P lease contact your authorized Audi dealer if a
bulb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­ placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
p lode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bu lbs in gas discharge lamps .
_& WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause ser ious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified wo rk­
shop . Serious personal injury may result
from improperly performed work .
(D Tips
-If you still prefer to replace the light
bulbs yoursel f, be aware that the engine
compartment is a hazardous area to
work in
c:::> page 222<=::> .&.
- It is best to ask your authorized Audi
dealer whenever you need to change a
bulb .
