not used then is being generated in o rder to
maintain an optimal battery charge level.
(D Tips
- Energy management cannot overcome
the laws o f physics. Note that the charge
l evel and length of the battery life are
li mited .
- When the starting ability is endangered,
the (•) indicator light turns on
c> page20.
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is p laced on the battery when
driving short distances, in traffic, and at co ld
times of the year. A lot of energy is used but
little is generated.
It is also critical when the
engine is not running but electrical equip­ ment is switched on . In this case, energy is
used but none is generated .
In situations like this, energy management
will actively regulated the distribut ion of en­
ergy.
L ong periods wi thout u se
If you do not drive your vehicle for several
days or weeks, e lectrica l equipment is gradu­
ally sca led back or switched off. This reduces
energy use and ensures the vehicle will be
able to start after long periods of time. Some
conven ience functions such as opening with
the remote control key may not be ava ilable.
These convenience functions w ill be availab le
again o nce you swi tch the ign ition on and
start the engine.
With the engine switched off
For example, if you listen to the radio when
the eng ine is sw itched off, the battery w ill
d rain .
A warning text w ill appear if energy consump­
tion could impair starting ab ility .
The message shows that you need to start the
engine in order to charge the battery.
With the en gine running
Although e lectrical energy is gene rated while
driving, the battery can dra in. This can happen
when litt le energy is generated, and much is
u sed and the charge leve l of the battery is not
optimal.
T o restore the balance of ene rgy, components
that require large amounts of energy are tem­
porari ly scaled back or switched off. Heating
systems in particular require a great deal of
energy. If you notice, for example, that the
seat heating* or rear window defroster is not
worki ng, then it has been temporar ily reduced
or switched off . These systems are available
again as soon as the energy balance has been
resto red.
In add ition, you may notice that the idle
speed has slightly increased. That is normal
and no cause for concern. Due to the in­
c reased idling speed, the additional required
energy w ill be gene rated and the battery will
be charged.
Notice about data
recorded by the Event
Data Recorder and
vehicle control
modules
E v ent D ata Reco rder
This vehicle is equ ipped with an Event Data
Recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an a irbag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle's systems per­
formed . T he EDR is des igned to record data
related to vehicle dynam ics and safety sys­
tems fo r a short period of time, typically
30 seconds or less . The EDR in this vehicle is
designed to record such data as:
- How various systems in your vehicle were
operating;
- Whether or not the driver and passenge r
safety belts were b uckled/fastened;

198 Driving and the environment
can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma intained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the function of the emission control
system and could lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating properly, the exhaus t gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Placing your vehicle
out of service
If you wou ld like to take your vehicle out of
service for a longer t ime, contact your author­
ized Audi dealer or qualified repair facility.
They will advise you of important measures,
such as corrosion protection, maintenance
and storage procedures. Also follow the infor ­
mat ion about the battery
¢ page 223.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors: -your
personal driving style
- operating conditions
- technical limitations
If you ant ic ipate what you need to do next and
drive econom ically, you can easily cut your
fuel consumpt ion by 1O-lS percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
(D 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, which will vary depending upon vehi­
cle load and speed, road and weather con­
ditions, trip 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
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traffic light is red.
Avoid full throttle '
Driving at moderate speeds saves fuel and
improves your mileage.
.,. Try and keep well below your car's maximum
speed.
Acce lerating gently reduces fue l consump­
tion, engine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emissions and en­
gine noise increase disproportionate ly at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption wi ll
be reduced by one half. Never drive faster

than the posted speed limit and weather con­
ditions permit. Reducing unnecessary idling
Even wh en your car is just idling it burns up
fuel.
.,. Shu t the engine off when you a re not dr iv ing
the vehi cle.
... Do not warm up the vehicle by letting the
engine run at idle.
It is effic ient to switch off the eng ine when
stopped at railroad crossings and long red
lights. Turning the engine
off for just 30-40
seconds saves more fu el than is burned by
starting the engine again.
It takes a long time fo r the engine to wa rm up
fu lly when it is running at idle. However , wear
and noxious emissions are especially high
when the engine is wa rming up. So you should
drive away as soon as you start the eng ine and
avoid running at h igh RPM while the engine is
still warm ing up.
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
p roduces heat, which cou ld result in over­
heating or other damage to the vehicle or
other prope rty .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
.,. Have your vehicle serv iced at regular inter-
vals.
H aving your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . T he condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects fuel
c onsum ption.
Dri ving and the en vironm ent 199
Chec k your oil e ach t ime you fill your tank.
T he amou nt of oi l used is re lated to engine
load a nd speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has bee n 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 .
(D Note
- Have your veh icle ma inta ined 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 ion cont ro l system and cou ld lead
t o damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacture r.
- Do not alter or remove any device, such
as hea t shie lds, switches, ign ition w ires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips.
... Try to avoid dr iving sho rt distances with a
cold engine .
T he eng ine and catalytic conve rter have to
reach their optimal operati ng t emperature to
reduce fuel consumption and noxious emis­
sions effectively.
Just after starting, a co ld eng ine in a mid-s ize
ca r only achieves a fuel economy of 6 -8 mi les
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg ..,.

riods of time, you should cover the
leather to protect it from direct sun-
light. ...

220 Check ing and F illin g
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Vehicle Warranty.
@) For the sake of the environment
- Before changing your oi l, f irst make sure
you know where you can properly dispose of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden so il, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
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 sea led and generally re­
q ui res little attention .
The cooling system has been filled at the fac­
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -based coolant addi -
tive G l3 antifreeze with anticorrosion addi­
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces­
sary frost pro tection and protec ts metal com­
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil­
i ng po int of the coo lant .
Do not red uce the concentr ation of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main­
tain antifreeze protection and cooling efficie n­
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
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 wa­
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .
.&, WARNING "---
Before you c hec k anyth ing in the engine
compartment, a lways read and heed a ll
WAR NIN GS ~
page 214.
0 Note
- Before wi nter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
ma te conditions. This is especi ally impo r­
tan t if you live in a reg ion where the win­
ter is extreme ly cold . If necessary, in­
crease the p roportion of coo lant add itive
to 60% .
- Whe n adding coolant additive to yo ur
cooling system, remembe r:
- We recommend us ing on ly coola nt ad­
d itive Gl2++ or Gl3 (check the labe l)
fo r your vehicle. This coolant additive is
a va ila ble at au thorize d Au di dea le rs.
Other types of antifreeze can sign ifi­
ca ntly reduce corrosion p rotection. The
resu lting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to yo ur vehicle's engine coolant .
Add ing radiator repair f luid may adverse­
ly affect the function and performance of
your cooling system and cou ld resu lt in
