according to t he needs of the individua l compo­
nents. It regu lates consumption , so that more
e lectr ical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.

ate the limits of physics . Cons ider that the
power and life of a battery are limited.

What you should know
The highest priority is given to maintaining start­
ing capability.
The batte ry is severely taxed in short-distance
driving, in c ity traffic and d uring the co ld time of
year. Abundant electrical energy is req uired, but
only a little is generated . It is also c rit ica l if the
engine is not runn ing and electrical components
are turned on . In this instance energy is be ing
consumed but none is be ing generated .
It is in precisely t hese situations that you will no­
tice energy management active ly regulat ing the
d istr ibut ion of energy .
Vehicle stands fo r an e xtended period
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. T his reduces
energy consumption and ma inta ins starting ca­
pab ility over a longer period . Some of the con­
ve nience funct ions may not ope rate, such as the
i n terio r lights or the powe r seat adjustment. The
conven ience f unc tions w ill be available again
when yo u switch on the ign it io n and s tart the en­
g ine.
With the engine turned off
I f you listen to t he radio, fo r example , with the
engine tu rned off o r use other MMI functions,
the batte ry is being discharged.
If start ing capabili ty is jeopardized due to energy
consumpt ion, a message appears in t he M MI dis­
p lay. The message indicates that the system wi ll
176 b
e switched off a utomat ica lly in a moment . If
you wish to continue using the functions, you have to sta rt the eng ine.
With the engine running
Althoug h elec trica l energy is gene rated w hen t he
vehicle is bei ng drive n, the batte ry can become
discharged. This happens mostly when little en ­
ergy is being generated and a great dea l con­
s u med and the battery 's state of charge is not
optimal.
To bring the energy balance back into equilibri ­
u m, consumers whic h require espec ia lly large
amounts of energy are temporar ily cut back or
switched off. Heating systems in particular re­
quire a great dea l of energy. If you notice, for ex­
ample, that the heated seats* o r the heated rear
window are not heati ng, they have bee n tempo­
r arily cut back o r switched off . These systems will
be available again as soon as the ene rgy balance
has been res tored.
You w ill also no tice that eng ine idle speed has
been increased slig htly . T his is no rma l and not a
ca use for concer n. By in cr easi ng engine idle
speed t he ad ditional energy required is gene rat­
ed and the battery is charged.

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
F ue l economy, environmenta l impact, and we ar
on your engine, brakes and tires la rgely depend
on three factors :
- you r persona l dr iving sty le
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your fue l
consumption by
10-15 percen t. This section will
g ive you some tips on how you can help the envi ­
ronment and yo ur pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not cor re­
spond to your actual consumption on the
road, which will va ry depending upon vehicle
load and speed, road and wea ther condi tions,
t rip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating a nd braking .
Veh icles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next , you will need to brake less and, thus, accel­
e rate less . let the vehicle coast wheneve r possi ­
b le -fo r example when yo u see that the next traf­
fic light is red .
Driving and the envir onment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car 's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fuel consumption, exhaust emissions and engine
noise increase disproport ionately 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 cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run
at idle.
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad cross ings, or at traff ic lights that have long waits
on red . Turning the engine off for just
30 -40 sec ­
onds saves more f uel than is burned starting the
. . engine again.
It takes a long time for the eng ine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially h igh when
the engine is warming up . So yo u should dr ive
away as soon as you start the eng ine and avoid
runn ing at high rpms w hile the engine is st ill
warming up .
(D Note
Do not leave eng ine idling unattended after
s tart ing. If wa rning lights sho uld come on to
i ndicate improper operation, they would go
unheeded . Extended idling also prod uces
heat, which could resu lt in overheating or
other damage to the vehicle or other proper­
ty.

Check ing and F illing
@ For the sake of the environment
- Under no circumstances can the oil come in
contact with the sewage network or the soil.
- Observe and fo llow legal regulations when
disposing of empty oil containers.
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion .
Before you che ck anything in the eng ine compart ­
ment,
always read and heed all WARNINGS ¢ A
in Working in the engine comportment on
page 191.
The engine oil must be changed according to the i n tervals 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 circ umstances the eng ine oi l sho uld
be changed more frequently. Change oil more of­
ten if yo u drive most ly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it 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 t he engine has been run ning for a
short t ime . T his is normal and is not a reason to
cha nge the oil mo re often than recommended .
Because of the prob lem 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 aut ho rized
Audi dealer o r
a qualif ied se rvice station .
If you choose to change your o il yourself , please
note the following important informat ion:
A WARNING
To re duce the risk of pe rsonal injury if you
must c hange t he engine oil in your ve hicle
yo urs elf:
- W ear eye protection .
196
-
-To reduce the r is k of burns from hot engine
oil, let the engine cool down to the touch.
- W hen removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm pa rallel to the ground to
he lp prevent hot oil from run ning down your
arm .
- Drain t he oil into a container designed for
this purpose, one large enough to hold at
leas t the tota l amou nt of oil in you r engine.
- Engi ne oil is poisonous. Keep it well out of
the reach of childre n.
- Continuous contact wit h used engine o il is
ha rmf ul to your skin. Always protect your
skin by washi ng oil
off thoroughly with soap
and wate r.
(D Note
Neve r mix oil additives with yo ur engine oil.
These additives can damage your e ngine and
adverse ly affect your A udi L imi ted New Vehi­
cle Warranty .
@ For the sake of the environment
-Be fore chang ing you r oi l, first make sure
you know where you can properly dispose o f
t h e used oil.
- Always dispose of used e ngine o il pro perly .
Do not d ump it on garden so il, wooded
areas, into op en streams o r down sewage
drains.
- Recycle used e ngine o il by tak ing it to a used
eng ine oil collect io n fa cil ity in you r area, o r

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 coolin g system is sealed and generally re­
quires little attention .
The coo lin g sys tem h as been filled a t the fac to ry
wi th a pe rmanent coolan t which does not need to
be changed. The coo lant consists of a mixture of .,.

.... N
0 I­co .... .... specially conditioned water and the man ufactur­
er's glycol-basedcoo lant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
e ls; 60% for Canadian models). This m ixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing system from corrosion and scaling.
It also
raises the boiling point of the coolant .
Do not reduce the concentration of the coolant in
the summer by adding plain water.
Th e propor­
tion of coolant addit ive must be at l eas t 50° /4
but not more th an 60 %
to maintain antifreeze
p rotection and cooling efficiency. If the coolant
frost protec tion is too low, the coolant co uld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at the
factory for temperatures down to:
- -31 °F (- 35 °C) USA
- -40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
Q &. in Working in the engine compart­
ment on page 191.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­
dit ions. This is especially important if you
li ve in a reg ion where the w inte r is ext reme­
l y co ld. If ne cessary, in cre ase the proport io n
of coo lant add itive to 60%.
- When addi ng coolant addit ive to you r cool­
i ng system, remember:
- We recommend using only coolant addi­
tive Gl2++ or Gl3 for your ve hicle. T his
coolant additive is available at authorized
Audi dea lers. Othe r types of antifreeze can
significant ly reduce cor ros ion p rotection .
Check ing and Filling
The resulting co rrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator lea k sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could resu lt in damage not cov­
ered by your New Veh icle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.
F ig. 163 Engine compa rtment: Cover on the coolant ex ­
pans ion tank
.. Before you check anything in the engine com­
partment,
al ways read and heed all WARN ­
INGS
q ..&. in Working in the engine compart­
ment on page 191.
.. Park your ve hicle on a leve l sur face .
.. Tu rn off the ignit io n .
.. Read the eng ine coolan t level from the coo la nt
expansion tank
qfig . 163, Qpage 193,
fig. 160 .
With a cold engine, the coolant level
should be between the " MIN" and "MAX" mark­
ings. When the engine is warm, the level may
be slightly above the "MAX" marking.
The location of the coolant expansion tank can be
seen in the engine compartment illustration
qpage 193.
To obtain an accurate reading, the engine must
be switched off.
T he expansion ta nk in your veh icle is eq uipped
with an electric coo lant level senso r.
When the coolant leve l is too low, the warning
light i n the Auto-Check System
Q page 17 will
197

Check ing and F illing
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec ­
tr ic coolant level sensor, we still recommend you
check the coo lant level from time to time.
Coolant los s
Coolant loss may indicate a l e ak in the cooling
system. In the event of coolant loss, the cooling
syst em should be insp ected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e aled system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and allow it to cool
down .
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction wh ile apply ing
l ight, downward pressure on the top of the
cap .
- To avo id being burned, do not sp ill anti ­
freeze or coolant on the exhaust system or
hot eng ine parts . Under certain conditions,
the ethy lene g lycol i n engine coolant can
catch fire.
{Q) Note
Do not add any type of radiator leak seala nt
to your veh icle's engine coolant . Adding radia­
to r repa ir fluid may adversely affec t the func­
tion and performance of yo ur cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty.
Adding coolant
Be very careful when adding engine coolant.

Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bu lb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the eng ine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, parts must be
Fuses and bulbs
correctly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
hous ings that have not been properly resealed.
For your sa fety, we recommend that you have
your authorized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas discharge lamps (Xenon lights)*:
Due to the high e lectr ica l voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker .
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light)* life-threatening injuries
can resu lt from improper handling of the
high -vo ltage portions of such lamps!
- Only your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. There are parts w ith
sharp edges on the openings and on the bulb holders that can cause serious cuts . If
you are uncerta in about what to do, have
the wor k performed by an authorized Audi
dealer or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work.
(D Tips
- If you st ill prefer to replace the light bulbs
yourself, be awa re that the engine compa rt­
ment is a hazardous area to work
inq page191 q &_ .
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb.
