functions will be available again when you
switch on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off or use othe r MM I fu nc­
tions, the battery is being discha rged.
I f starting capability is jeopardized due to en­
e rgy consumpt ion, the fo llow ing warning ap­
pears in the MMI disp lay :
Plea se start the eng ine soon or th e sys tem
w ill b e turn ed off .
The warning ind icates that the system will be
turned off automatically after 3 m inutes . If
you wish to cont inue us ing the functions , you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is be ing driven, the battery can be­
come discharged . Th is happens mostly when
little energy is be ing generated and a great
deal consumed and the battery's state of
charge is no t optimal.
To br ing the energy balance back into equili ­
b rium, consumers which require especially
l arge amounts of energy are tempo rarily cut
back or swit ched off. Heating systems in par­
ticular requ ire a g reat dea l o f energy. If you
notice, fo r example, that the heated seats* or
the heated rear window are not heating, they have been temporari ly cut back or switched
off. These systems will be ava ilab le again as
soon as the energy balance has been restored.
You will a lso notice that engine idle speed has
been increased slightly . This is norma l and not
a cause for concern . By increasing engine idle
speed the add itiona l energy required is gener­
ated and the battery is charged.

Catalytic converter
It is very important that your emission con­trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.. Always use lead-free gasoline¢ page 215,
Fuel supply.
.,. Never run the tank down all the way to
empty.
.,. Never put too much motor oil in your en-
gine
¢ page 225, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be ­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
importa nt for the life of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust pipes, catalytic con­
verter or heat shields. During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
0 Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢ page 225.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned fuel could a lso get i nto
Dri vin g and en vironm ent 197
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not swi tch off the ignit ion while the
vehicle is mov ing.
- Do not continue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating o f the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec­
ommendat ions in you r Warranty &
M aintenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing properly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or filling the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are drivi ng on poo r roads, or over
c ur bs, s teep ramps, etc., ma ke certai n that
low -lying parts s uch as spoilers and exhaust
system pa rts do not bottom o ut and get dam­
aged.
T h is is espec ially true for veh icles w ith low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles. •

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"" Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­ tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
"" Shut the engine off when you are not driv­
ing the vehicle.
"" Do not warm up the veh icle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
bu rned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over-
Dri vin g and en vironm ent 199
'
heating o r othe r damage to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"" Have your veh icle serviced at reg ular i nter-
vals.
By having your veh icle regu la rly serviced by an
Audi dealer he lps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its sa fety and ability to
hold its value, it a lso affects
fuel con sump­
tion .
Check your oil e ach t ime you fill your tank .
The amount of o il used is re lated to eng ine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven .
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss io n cont ro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alter or remove any device, such
as heat shie lds, swit ches, ign it ion w ires,
valves, which are designed to p rotec t
your vehicle's Emission Control System
and other important vehicle compo­
nents .

214 Cleaning and protection
-When cleaning your safety belts, inspect
them for damage.
If you discover dam­
age, see your Audi dealer .
- Always read and heed all WARNINGS and
other information
c> page 204.
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Always switch off the ignition before clean­
ing the engine
c> .&..
Plenum panel
Remove leaves from the plenum pane l in front
of the windsh ield under the engine compart­
ment. This prevents the water dra in ho les
from becoming blocked, and it prevents de­
bris from entering the vehicle interior through
the heating and venti lation ducts .
Corrosion protection
The engine compartment and transmission
have been corrosion -protected at the factory.
Good ant i-corrosion treatment is very impor­
tant, particularly in the winter. If the veh icle
is frequent ly driven on salt treated roads , the
enti re engine compartment and plenum panel
should be tho roughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solutions
1l, or if
you have the engine washed, the anti-corro­ sion treatment is a lmost always removed as
well. It is therefore essential to have a long­ lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
engine compartment .
1l Use o nly the co rrect cle anin g so lu ti on s. Ne ver use gas­
o lin e or d ie se l fuel.
A WARNING
Be aware: The eng ine compartment of any
motor vehicle is a potentially hazardous
area .
- Before work ing in the engine compart­
ment, be sure to read the information
c> page 220.
-Before reach ing into the front panel, al ­
ways sw itch off the ignition . Otherwise,
the windshield wiper system could unin­
tentionally be switched on, possibly
causing personal injury from the moving
wiper linkage .
- Never reach into the area around or
touch the radiator fan. The auxiliary fan
is temperature controlled and can sw itch
on suddenly -even when the ignition is
off.
- Do not wash, wax or dry the engine with
the engine running . Moving or hot parts
could injure you.
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
to reach parts without protecting your hands and arms . You may cut yourself on
sharp-edged metal parts.
-Always read and heed all WARNINGS and
other information
c> page 204.

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 water and the manufacturer's gly ­
col-based coolant additive G12++ antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canadian models). This mix­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi ­
cle heating and engine cooling system.
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31 °F ( -3 5 °C) USA
- -40 °F ( - 40 °C) Canada.
You can mix the G12 ++ coolant additive with
other additives (G12+ or G12). Always check
with your authorized Audi dealer.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
~ .&. in Working in the engine
compartment on page 220.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checking and filling 22 7
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in­
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad­
ditive G12++ (check the label) for your
vehicle. This coolant additive is availa­
ble at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The result­
ing corrosion can cause a loss of cool­
ant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.
