Engine oil consumption
The engine in your vehicle dep ends on an ade
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
¢
page 198) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 217
wear as m ileage builds up, the oil consump
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev
el, see
Note .
If the yellow engine oil leve l warning symbo l

a lways rea d and he ed all WARN
INGS
~ &. in Working in the engine compart
ment on page 213.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di
minish gradually during normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently. Change
oil more often if you drive most ly short dis
tances, operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con
ditions, or have your vehicle where tempera
tures remain below freezing for extended pe
riods.
Detergent additives in the oil w ill make fresh
oil look dark after the engine has been run
n ing for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposa l,
along with the special tools and necessary ex
pertise required, we strongly recommend that
you have your oi l changed by an authorized

To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en-

touch.
- When removing the o il dra in p lug with

Always keep your forearm parallel to the
ground to help p revent hot oil from run

- Dra in the oil into a container designed
for this purpose, one large enough to hold at least the tota l amount of oi l in

- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact wit h used eng ine o il

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro
tects the engine from freezing in the winter .
The cooling system is sealed and generally re
quires little attention.
The cooling system has been filled at the fac
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with ant icorros ion addi
tives (50% for USA models; 60% for Canadian models) . This mixture both assures the neces
sary frost protection and protects metal com
ponents in the engine's cooling system from
corrosion and scaling.
It a lso raises the boil
ing point of the coo lant.
D o not reduce the concentration o f the coo l
ant in the summer by adding plain water .
The
proportion of coolant add it iv e mu st be at
lea st 50 % but not mo re than 60 %
to main
tain antifree ze protection and cooling efficien
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31° F(-35°C)USA
- - 40 ° F ( -40 °C) Canada.
I f you must add coo lant, use a m ixture of wa
ter and coolant addit ive. Mixing the coolant
addit ive wi th dist illed wate r is recommended.
_& WARNING
Before yo u check any thing in the engine
compartment, always read and heed all
WARNINGS
¢ &. in Working in the engine
compartment on page 213.
(D Note
- Before winter se ts in, have the coolant
checked to see if the coolant additive in
-
your vehicle is sufficient to meet the cli mate conditions . This is especia lly impor
tant if you live in a reg ion where the win
ter is extreme ly cold. If necessary, in
crease the proportion of coolant add itive
to 60% .
- When adding coolant additive to your
cooling system , remember :
- We recommend us ing on ly coolant ad
d it ive G12 ++ or G1 3 (check the labe l)
for your vehicle . This coolant additive is
avai lable at autho rized Audi dea lers .
Other types of antifreeze can signifi
cantly reduce corrosion protection. The
resu lting corrosion can cause a loss of
coolant and serious engine damage .
- Do not add any type of rad iator leak seal
ant to your vehicle's engine coolant.
Add ing radiator repa ir flu id may adverse
ly affect the function and performance of
your cooling system and could resu lt in

The expansion tank in your 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 15 will
illuminate until you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolant level
from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant .
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
&_ WARNING
-
The cooling system is under pressure and
can get very hot. Reduce the risk of scald
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in

Disconn ecting the battery terminal s
Some vehicle functions (power w indow regu

to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle

for repairs .
Vehicles not driven for l ong period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo
