INGS
c> A in General information on
page 203 .
~ Always follow the operating instructions for
the power washer .
~ Make sure that the jet o n the spray hose
produces a "fan shaped spray ".
~ Do not hold the spray no zzle too close to
soft materia ls.
W hen clea ning the vehi cle w it h a powe r wash­
e r
always fo llow the operating instruc tions.
Cleaning and protec tion 205
This applies particu la rly to the operating
pre ssure and the spraying di stance. Keep a
distance from soft materia ls such as rubber
hoses or insulating material as we ll as sensors
and camera lenses.
Do not use a jet which sprays water in a direct
stream or one that has a rotating jet.
Water tempera ture sho uld no t exceed 140 ° F
(60 °().
A WARNING
N eve r wash t ires with a jet that sprays wa­
ter in a direct stream . T hi s could cause in ­
v isib le damage to the t ires and weaken
them, even i f the spray is from a re lative ly
long distance and for a sho rt time. Dam­
aged and weakened tires can fail and cause
accidents and personal i njury .
(D Note
To avoid damaging your vehicle, a lways
make sure that the re is suffic ient d istance
between the spray head and soft materials
li ke rubber hoses, plast ic pa rts and sound­
deaden ing ma ter ia ls as well as sensors
and camera lenses. Never a im th e sp ray
head at the same point for a long time .
This also applies to cleaning headlights
and painted bum pers. Remembe r: the
cl oser the nozzle is to the surface of the
mater ia l, the greater the stress on the ma­
terial.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
-
The engine in your Audi is a sophisticated
powerp lant that was built to exacting specifi­
cations . This engine needs the r ight kind of
engine o il that meets spec ificat ions regarding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l
and changing oil within the time and mileage
interva ls printed in your vehicle 's Warranty
&
Maintenance book let matters a lot more to­
day than it did years ago. Audi has developed
a special quality standard for engine oil that
will help assure that your veh icle's eng ine will
get the lubrication it needs for proper opera­
tion.
Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast trad itional petrole -u
m -based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthet ic o r petro le um­
based eng ine oil, the oi l that you use m ust
conform to Audi's oi l quality standard
VW 502 00 to help keep your vehicle's engine runn ing smooth ly and help prevent the for­
mation of harmfu l deposits, sometimes called
"sludge," that over time can lead to expensive
repairs.
At the time of printing, engine oils ava ilable in
the U.S. and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthet ic eng ine oils . Th is does not mean,
howeve r, that every synthetic engine oil will
meet Audi o il standard VW 502 00 . So always
be su re that you use an approved oil.
To help prevent the formation of harmfu l de ­
pos its use only o il w ith the following specifi­
cations pr inted on the o il conta iner:
Audi oil standard VW 502 00
Oil container labels may carry the specifica­
tion sing ly or in combination with other desig ­
nations and oil quality standards.
V is cos ity
Engine o ils are graded a ccord ing to their vis­
cosity . The proper vis cos ity grade oil fo r yo ur
engine depends on climactic or seasona l con­
ditions where you drive. You can use oil with a
viscosity grade of SAE 5W40 across a ll tem­
perature ranges for norma l driving conditions.
However, if engine oil v iscosity g rade SA E
SW40 is not available , you can also use viscos ­
ity grade SAE SW-30 or SAE OW-40 as long as
it meets Audi oil qua lity standard VW 502 00
specifications.
Beca use engine oi l that meets the Audi oil
standard may not be availab le everywhere
when you need it, we strong ly recommend
that you a lways carry with you an extra quart
( li ter) of oil that express ly conforms to the
VW 502 00 spec ificat ion, in case you have to
top off the o il while o n the road . ..,_

Have the battery checked when you take your
vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years .
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec ­
trica l system for safety reasons
c::> &. in Re­
pair, care and disposal of the airbags on
page 156.
Disconn ecting the battery terminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicles not driven for long period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod
c::> page 192. Some of the convenience func­
tions may not operate, s uch as the inte rior
lights o r the power sea t adjustment . T he con­
ve nience fun ct ions wi ll be available again
when yo u switch on the ignition and start the
engine.
Winter operation
During the winter mont hs, ba ttery capaci ty
t ends to decrease as tempe rat ures d rop . Th is
is because more powe r is also consumed while
starting , and the headlights, rear window de ­
fogger, etc., are used more oft en.
Avoid unnecessary power cons umption, par­
ticularly in c ity t ra ff ic or when t raveling on ly
short distances. Let your a uthorized Audi
dealer check the capac ity of the vehicle bat ­
tery before winter sets inc::>
page 233. A well
charged battery w ill not only prevent starting
problems whe n the weather is cold, but will
also last longer .
Checkin g and fillin g 231
(D Tips
If your vehicle is left standing for seve ral
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 l uggage compart­
ment under the floor. Before you check any­
th ing in the luggage compartment,
read and
h eed all WARNINGS

234 Check ing and filling
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, rad io, etc ., as well
as the battery charger.
Battery replacement
The new bat tery must have the same specifi­
cations and dimensions as the original equip­
ment battery .
Intelligent energy man agement in your veh i­
cle is respons ible for d istributing the electr i­
cal energy throughout your vehicle
c::> page 192. The intell igent energy manage­
ment system w ill keep the engine battery
cha rged bette r than vehicles w ithout t his sys­
tem. To make sure the additional e lectrica l en­
e rgy is availab le once again after you have
changed the battery, we recommend that you install batteries of the same type and manu ­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. Your
author ized dealer must code the battery in
the energy management system to enable you
to use the energy management funct ions cor­
rectly after replac ing the battery .
The new battery must have the same capacity ,
voltage (12 volts), amperage, construct ion
and plug sealing.
When installing the ba ttery, make sure the ig­
n ition and all e lectr ica l consumers are sw itch ­
ed off .
{[) Note
Make sure the venti lation hose on the s ide
of the battery is connected, otherwise
fumes or battery ac id can leak out .
@ For the sake of the environment
Because of the problem of proper d isposa l
of a battery, we recommend your author ­
ized Aud i dealer change the battery for
you . Batter ies contain su lfuric ac id and l
ead and must a lways be disposed o f prop­
erly in compliance with a ll environmental
regulations. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi­
ronment .

For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It is becoming increas ingly more and more
d iff icu lt 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
bu lb. This applies especially to the light bulbs
in the front of your car which you can on ly
reach through the engine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, and parts must be correctly 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.
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker.
LED headlights * require no maintenance .
Please contact your authorized Audi dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head-
Fuses and bulbs
light bulbs can cause serious personal in­
jury and death.
- Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualified workshop should change the bulbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop . Ser ious personal injury may result
from imprope rly performed wo rk.
Q) Tips
-If you must replace the light bulbs your­
self, always remember that the eng ine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
~page 213, Engine
compartment
Q & .
-It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .
