Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine .
If a vehicle with a conventional energy system
is not driven for a long period of time, the bat­
tery is discharged by idling current consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to start the engine .
Intell igent energy management in your vehi­
cle handles the d istribution of electrical ener­
gy. Starting ab il ity is markedly imp roved and
the life of the battery is extended .
Basically, energy management consists of
batt ery diagno sis, idlin g current man ag e­
m ent
and dyn ami c en ergy manag emen t.
Batter y diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determ ine
battery vo ltage, battery current and battery
temperature. This determ ines the current
state of charge and the powe r of the battery.
Idling curr ent man agement
Idling current management reduces energy
consumption while the vehicle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy s upply to the various electr ical compo ­
nents . Data from battery diagnosis is consid­
ered.
D epending on the batte ry's state of charge,
i nd ividua l consumers are gradual ly t urned off
to prevent excess ive d ischarge of the battery
and thus maintain starting capability .
Dynam ic en ergy management
While the vehicle is being driven, dynamic en­
e rgy management dist ributes the energy gen­
e rated according to the needs of the individu­
a l components.
It reg ulates cons umption, so
that more electrical energy is not being used
Int ellig ent technolog y 155
than is being generated and ensures an opti ­
mal state of charge for the battery.
(0 Tips
- But even energy management canno t
negate the limits of physics . Consider
that the power and life of a battery are
limited .
- If starting ability is threatened, you are
informed by a warning
r::!)poge 156,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short -distance
driving, in city traffic and during the cold time
of year. Abundant electrical energy is re­ quired, but only a little is generated .
It is also
critical if the engine is not running and electri­
cal components are turned on . In this in­
stance energy is be ing consumed but none is
being generated.
It is in precisely these situations that you will
notice energy management actively regulat ­
ing the d istribution of energy .
Vehicle stands for an e xtended peri od
If you do not drive your vehicle over a period
of several days or weeks, e lectr ical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in ­
ta ins start ing capability over a longer period .
Take into considerat ion that when you unlock
your vehicle, some convenience functions, such as the remote key or power seat adjust­
ment, may not be available . The conven ience
funct ions w ill be available again when you
tu rn o n the ignition and start the engine .
With the engine turned off
If you listen to the radio, for example, w ith
the engine turned off, the battery is being d is-
charged.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not con tinue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reac h 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 inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, t he exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
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 persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 159
fuel consumption by 10 -15 percent. This sec ­
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as publishe d
by ENVIRONME NTAL PROTEC TION 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
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic 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 lerat ing gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at app roximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Nev er drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

172 Cleaning and protection
• Once the stain is no longer visib le, use a soft
dry cloth or tissu e to soak up the moisture .
Do not use leather cleaning produc ts on Al ­
cantara .
You may use a suitable shampoo fo r remov ing
dust and dirt.
Dust and grit in the pores and seams can
scratch and damage the surface . If the car is
l eft stand ing i n the sun fo r long pe riods, the
A lcantara should be p rotected against direc t
sun light to preven t it from f ad ing. Slig ht color
va ria tions will develop in normal use an d are
not an indication of material deterioration .
CI) Note
-Never use chemi cal solven ts (e.g. lighter
fl uid , turpentine), waxes, shoe po lish or
s imilar products on Alcantara ® sur faces.
- To avoid damage, have stubborn stains
r emoved by a commerc ia l cleaning spe ­
cia list.
- Do no t use br ushes, st iff sponges or sim­
ilarly abrasive cleaning a ids.
Safety belts
Only well-maintained safety belts work relia ­
bly when ne eded .
Heavily soiled safety belts may not retr act
p rope rly.
• Keep be lts clean.
• For cleaning, use a m ild soap and wate r sol­
u tio n. Le t be lts d ry thoro ughly and away
from direct s unli gh t.
• Do no t all ow ine rtia reel safety be lts to re­
t ract before they are completely d ry .
• Check the condition of your safety belts
reg­
ularly.
A WARNING
Damaged safety belts can break in a crash.
1l Use o nly th e co rrec t cle anin g so lu ti on s. Ne ver use gas­
oli ne or d ie se l fuel.
- Anyth ing that might damage yo ur sa fety
be lts could mean that you and your pas­
sengers would not be adequate ly pro ­
tected in an accident .
- Safety belt performance depends on co r­
rect insta llation. Never remove be lts
from the veh icle to clean them .
- Do not use chemical clea ning agents,
b leach or dyes . They have corrosive prop­
ert ies which wea ken the webb ing .
- When clean ing your safety be lts, inspect
them for damage . If you discover dam ­
age, see your Audi dea ler .

Engine compartment
Be especially careful when cleaning the en­
gine compar tment.
Always switch off the ignition before clean­
ing the engine<=;>.&, .
Plenum panel
Remove leaves from the plenum panel in front
of the w indshield under the eng ine hood . This
preve nts the water drain holes from becomin g
block ed, and it prevents debris from enter ing
the ve hicle interio r thr ough the heating and
ventilat ion duc ts.
Corrosion protection
T he eng ine compartment and transmission
have been corrosion -protected at the factory .
G ood anti- corrosio n treatmen t is very impor­
tant, par ticul arly in the w inter.
If the vehi cle
is frequently driven on salt t reated roads, the
entire engine compa rtment an d plen um panel
sho uld be thoro ughly cleaned at the end of
winter and retreated to prevent salt damage.
At the same time, the unde rside of the vehicle
shou ld be washed as well.
If the engine compa rtment is cleaned at any
time with grease remov ing solutions
1> , or if ..,.

you have the engine washed, the anti-corro­sion treatment is a lmost always removed as
wel l. It is therefore essential to have a long­
lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
engine compartment .
A WARNING
Be aware: The engine compartment of any
motor vehicle is a potentially hazardous
area.
- Before working in the engine compart­
ment, be sure to read the informat io n
c::.>page 172.
- Before reaching into the front plenum
pane l, always remove the ignition key.
O therw ise, the windshield wipe r system
cou ld unintentiona lly be switched on,
poss ibly causing pe rsonal 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 switch
on suddenly- even when the ign it ion is
off.
- Do not wash, wax or dry the engine w ith
the engine running. Moving or hot parts cou ld injure you .
- Do not clean the underside of the chas­ sis, fenders, wheel covers, or other hard
to reach parts w ithout protecting your
hands and arms. You may cut yourse lf on
sharp-edged metal parts .

snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 - 86).
(D Note
Never drive your vehicle until the fuel tank
is completely dry. The irregular supply of
fuel can cause misfiring. Gasoline could
enter into the exhaust system and damage
the catalytic converter.
Refuelling
Fig. 132 Driver's door: Un locking fuel filler flap
Fig. 133 Fuel cap hooked on the opened fue l filler flap
When adding fue l, the ignition and any ce llu­
lar phones in the vehicle must be switched
off .
Taking the fuel cap off
• To open the fuel filler flap, pull the button
9fig. 132.
• Unscrew fuel filler cap counter-clockwise
and hang it on the fuel filter flap¢
fig. 133 .
Refuelling procedure
• Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it will
go.
• Select a medium refuelling rate so that the
nozzle switches off automatically when the
tank is full.
Putting the fuel cap back on
• After filling your tank, twist the fuel filter
cap clockwise until you hear a definite click.
• Close the fuel filler flap.
To avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 28
to come on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filter neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re­
fueling. The electromagnetic radiation
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel container.

-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wa it until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
-If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever to "P" (Park).
Checking and filling 179
-Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts . Tie back hair before
starting, and wear no clothing that will
hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards

186 Checking and filling
Before you check anything in the engine com­
partment,
alwa ys r ea d and heed all WARN­
INGS ¢ A in Working in the engine
comportment on page 178.
• Switch the ignition off .
• Read the coo lant level at the coolant expan­
s ion tank ¢
fig. 141 . With a co ld engine, it
must be above the "min" mark. W ith a hot
engine, it can be a little above the indicated
range.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration .
To obtain an accurate reading , the engine
must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor .
When the coolant level is too low, the warning light in the Auto- Check System ¢
page 31 will
blink until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sen sor, we still rec­
ommend you check the coolant leve l 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 A udi 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.
@ Note
Do not add any type of ra diator leak seal­
ant to yo ur vehicle's eng ine coolant. Add ­
ing radiator repair f luid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine comport­
ment on page 178 .
•Turnoff the engine.
• Let the eng ine cool down.
• Place a thick rag ove r the coolant expansion
tank
