Engine compartment overview
The most important check points .
-For safety reasons, the hood must always be
latched securely while dr iving. Because of
this, always check the hood after closing it
to make sure it is latched correctly . The
hood is latched if the front corners cannot
be lifted .
-If you notice that the hood is not latched
while you are driving, stop immed iate ly and
close it, because d riving when the hood is
not latched increases the r is k of an accident.
-If the hood is not latched comp letely, it

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion .
Before you check anyt hing in the eng ine compart ­
ment,
alwa ys read and heed all WARNING S¢.&.
in Working in the engine comportment on
page 314.
The engine oil must be changed accord ing to the
intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oi l should
be changed more frequently. Change oil more of­
ten if you drive most ly short distances, operate
the vehicle in dusty areas or under predominant ly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. Th is is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil c hanged by an authorized
A udi de aler or
a qualified service station .
If you choos e to change your o il y our self , please
note the following important information:
A WARNING
T o red uce the r isk of pe rsonal injury if yo u
must change the engine oil in your ve hicle
yourse lf:
-Wear eye p rotection.
-To reduce the risk of burns from hot engine
o il, let the eng ine cool down to the touch.
-
-Whe n removing the o il drain plug with your
fingers, stay as far away as poss ible. A lways
Ch eck ing and F illing
keep your forearm pa rallel to the ground to
he lp prevent hot oil from running down your
arm.
-Drain the oil into a container designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in your engine.
-Engine oil is poisonous. Keep it well out of
the reach of children.
-Continuous contact with used engine o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
a nd water.
@ Note
Never mix oil additives with yo ur engine oil.
These additives can damage your engine and
adverse ly affect your Audi limited New Vehi­
cle Warranty.
@) For the sake of the environment
-Before chang ing your oi l, first ma ke sure
you know where you can properly d ispose of
the used oil.
-Always dispose of used engine o il properly.
Do not dump it on garden so il, wooded
areas, into open streams o r down sewage
dra ins.
-Recycle used eng ine o il by tak ing it to a used
eng ine oi l collec tion fac ility in yo ur area, or
contact a se rvice station.
Cooling system
Coolant
The eng ine cooling system is fi lled w ith a mixture
of purified water and coolant additive at the fac­
tory. This coolant must not be not changed.
T he coo lant level is monitored through
the . in­
dicator light
¢page 23. However, we do recom­
mend occasionally checking the coolant leve l
manual ly.
If you must add coo lant, use a mixture of water
and coolant additive. Mixing the coolant add itive
with dist illed water is recommended.

@ For the sake of the environment
i Batteries contain polluting substances such
as sulfur ic acid and lead. Contact an author­
i zed Audi dealer or authorized Audi Service
Fac ility for more informat ion.
Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually sca led
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of
time<=> page 145 . Some convenience
funct ions, such as interior lighting or power seat
adjustment, may not be available under certain
circumstances . These convenience functions will
be available again once you switch t he ignition on
and start the engine .
Even when electrical equipment is switched off,
the equipm ent can still drain the vehicle battery
if the vehicl e is not driven for long periods of
time. Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery.
The vehicle battery must be charged every month
to reduce the risk of this happening
<=> page 323.
Contact an authorized Aud i dealer or authorized
Audi Service Fac il ity for more information.
Winter operation
Cold weather places higher demands on the vehi­
cle battery. This results in reduced starting abili­
ty. Have the vehicle battery checked by an au­
thorized Audi dealer or authorized Audi Service
Fac il ity before the cold time of year .

damage (punctures, cuts , cracks
and bulges). Remove foreign ob­
jects from the tire tread .
.,,. If driving over curbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
.,,. Have faulty tires or rims re­
placed immediately .
.,,.Protect your tires from oil ,
grease and fuel.
.,,. Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled .
.,,.Lay tires flat when storing and
store them in a cool, dry locat ion
with as litt le exposure to light as
possible .
&_ WARNING -
-Never drive faster than the
maximum permitted speed

This increases the risk of an
acc ident because it can cause
the tire to burst.
-Always adapt your driving to the road and traffic condi-
Wheels
tions. Drive carefully and re ­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice .
@ N ot e
-Please note that summer and
winter tires are designed for
the condit ions that are typical
in those seasons. Audi recom­
mends using winter ti res dur ­
ing the winter months. Low
temperatures significantly de­ crease the e lasticity of summ­
er tires , which affects traction
and braking ab ility . If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be
used in winter driving condi­
tions . The surface of the rims
does not have sufficient corro­
sion protect ion for this and
could be permanently dam­
aged by road salt or similar
substances.

products with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the ve­
h icle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, r inse
off heavy deposits with
p lenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a microfiber cloth.
A lso, wash the underside of yo ur vehicle once
road sa lt stops being used for the season .
Pressure washers
When washing your veh icle w ith a pressure wash­
er , al ways fo llow the operating instructions pro­
vided with the press ure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at the
344
seals on the side windows, doors, lids or the sun­
roof* or at tires, rubber hoses, insulating materi ­
a l, sensors* or camera lenses* . Keep a distance of
at least 16 in (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use cone nozz les or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °() .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshie ld wipers are
off . Follow instruc ­
tions from the car wash operator, especially if
there are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.

in g down using a soft sponge or cl eaning br ush.
Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large part icles from you r vehi ­
cle. Insects, grease spots and fingerprints are
best removed with a special cleaner for matte
finish paint .
Apply t he product using a microfiber cloth. To
avoid damaging th e paint surface, do not use too
much pressure.
R inse the vehicl e thoroughly with wate r. Then
clean using a neutra l shampoo and a soft micro­
f iber cloth .
