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.

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.

California Proposition 65 Warning:
- Battery posts, terminals and re lated acces­
sories contain lead and lead compounds,
chemica ls known to the State of California
to cause cancer and reproductive problems.
Wash hands after handling .
@ Note
-If the vehicle will be parked for long periods
of time, protect it against the cold so that it
will not be destroyed by "freezing"
<=>page 323.
-There are electrical components under the
cargo floor behind a trim pane l that warm
up during operation. To reduce the risk of
the components overheat ing, do not store
objects such as blankets under the cargo
floor . If they overheat, the components wi ll
switc h off temporarily. This will be ind icat ed

@ 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 .
