.,&_ WARNING
-When you leave your vehicle - even if on
ly briefly - always take the ignit ion key
with you. This applies particularly when children remain in the vehicle. Otherwise
the children could start the engine or op
erate electrical equipment (e.g. power
windows). The power windows are func
tional until the driver's door or passeng
er's doo r has been opened.
- Be careful when closing the w indows.
Check to see that no one is in the way, or
serio us injury could result!
- When locking the vehicle from outside,
the vehicle must be unoccupied since the
windows can no longer be opened in an
emergency .
{D Tips
-When you open the doors, the windows
automatically lower abo ut 10 mm.
- When the window in the driver's or pas
senger's door is complete ly open, it will
raise approximately 25 mm when the
door is opened. The window will lower
again when you close the door.
- After the ignition has been switched off,
the windows can sti ll be opened or
closed for about 10 minutes. The power
windows are not switched off until the
dr iver's door or passenger's door has
been opened .
What to do after a malfunction
The one-touch open and close function must
be reactivated if the battery has been discon
nected.

@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not corre
spond to your actual consumption on the
road, wh ic h will vary depend ing upon vehi
cle load and speed, road and weather con
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac
celerating.
~ Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac
celerating . If you anticipate what is go ing to
h appen next, you will need to b rake less and,
thus, accelerate less. Let the vehicle coast
wheneve r poss ible -fo r example when you see
that the nex t tr affic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
~ T ry and keep well below your car's max imum
speed.
Accelerating gent ly reduces fuel consump
tion, engine wear, and does not dist urb the
environment.
Fuel consumption, exhaust emissions and en
g ine no ise increase d ispropo rtionately at high
speeds. If you dr ive at approxima tely three
q uarters of top speed, fue l consumption will
be red uced by one ha lf. Never dr ive faste r
than the posted speed limit and wea ther con
d itions permit.
Reducing unnecessary idling
E ven when your car is just idling it burns up
fuel.
~ S hu t the engine off when you a re not dr iv ing
t h e vehi cle.
Dri vin g and en vironm ent 207
~ Do not warm up the vehicle by lett ing the
engine run at id le .
T he id ling phase is au toma tic ally red uced for
vehicles with the Start/S top system . It is eff i
cient to switch off the engine in vehicles with
out the Start-Stop-System when stopped at
railroad crossings and long red lights. Turning
the engine off for just 30-40 seconds saves more fuel than is burned by start ing the en-
. . gme again .
It takes a long t ime for the engine to warm up
fully when it is run ning at id le. However, wear
and noxious emissions are especia lly high
when the eng ine is warm ing up. So you should
dr ive away as soon as you start the engine and
avo id running at high rpms whi le the engine is
sti ll warming up.
(L} Note
Do not leave eng ine idling unattended af
ter start ing.
If wa rni ng lights sho uld come
o n t o indi cate improper ope rat ion, t hey
wo uld go unheeded. Extended idlin g also
produces heat, wh ich could res ult in ove r
heating or other damage to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
~ Have your ve hicle servi ced at reg ular i nter-
vals .
By havi ng your ve hicle regu la rly se rviced by an
Audi dealer he lps to ensu re tha t it ru ns prop
erly and economically . The condition of your
vehicle not on ly affects its safety and ability to
ho ld its va lue, it a lso affects
fuel consump
tion .
Check your oil each t ime y ou fill your tank.
The amou nt of o il used is re lated to engine
l oad and speed.
It is normal for the oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has been d riven. .,..

Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting specifi
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can r un
smooth ly and reliably. Choosing the right o il
and changing oil within the t ime and mileage
intervals p rin ted in you r vehicle's Wa rranty
&
Maintenance booklet matters a lot more to
day than it did years ago . Audi has deve loped
a specia l quality sta ndard for engine oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera
tion.
Page 233 of 306

current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hanging the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilomete rs) and
time intervals specified in your vehicle's War
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs .
Changing the oil at the recommended inter
vals is so very important because the lubricat
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author
ized Audi Service Advisor .
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con
ditions, or when you use your vehicle where
temperatures stay below freezing point for long periods.
Detergent addit ives in the oil will make fresh
oil look dark after the eng ine has been run
ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine). Your
Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to fol
low recommended maintenance and use re
quirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
Your dealer will have to deny warranty cover
age unless you present to the dealer proof in
Checking and filling 231
the form of Service or Repair Orders that all
scheduled maintenance was performed in a
timely manner.
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 204) 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
in the instrument cluster
II! lights up, you
should check the oil level as soon as possible
¢
page 232. Top off the oil at your earliest
convenience

.,. Switch off the ignit ion.
.,. Read the engine coolant level from the cool
ant expansion tank¢
fig. 196, ¢ page 229 ,
fig. 193 .
With a cold engine, the coolant
level should be between the "min" and
"max" mar kings. When the engine is warm,
the leve l may be slightly above the "max"
marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration¢
page 229 .
To obtain an accurate read ing, the eng ine
must be switched off.
The expans ion tank in you r vehicle is equipped
with an electric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto -Check System ¢
page 17 will
illum inate u ntil you add coolant a nd the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolan t leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool-
Checkin g and fillin g 235
ing system should be inspected immediately
by your authorized Audi dealer . It is not
enough merely to add coolant.
In a
s ea led system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald
ing from hot coolant by follow ing these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escap ing f lu id and steam by cover ing the
cap with a la rge, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap
plyi ng light, downward pressure on the
