Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servici ng or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a co llision.
There are some important th ings you have to
know to make sure that the effect iveness of
the system will not be impa ired and that dis
carded components do not cause injury or po l
lute the env ironment.
_& WARNING
Improper ca re, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpected ly:
- Never cover, obstr uct, o r change the
steering wheel horn pad or airbag cover
or the instrument pane l or modify them
in any way.
- Never attach any objects such as cu
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
pane l, use only a soft, dry cloth or one
moistened w ith plain water. Solvents or
cleaners co uld damage the airbag cover
o r change the stiffness or strength of the
material so tha t the airbag cannot de

Replacing wh eels/ tire s
Vehicles w ith all-wheel drive must a lways
have tires of the same size. Also avoid tires
with different tread depths. For details see
page ¢
page 284, New tires and replacing
tires and wheels .
.&_ WARNING
Always adjust your driving to road and traf
fic conditions . Do not let the extra safety
afforded by all-wheel dr ive tempt you into
tak ing extra risks.
-Although the all-wheel dr ive is very ef
fective, always remember that braking
capacity is limited by t ire traction . You
sho uld therefore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning). If this sho uld occ ur, you
w ill have no warning from a sudden in
crease in engine speed as with a front
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con
ditions -risk of c rash.
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.
I f a vehicle w it h a conventional energy system
i s not driven for a long pe riod of time, the bat
tery is disch arged by idling c urrent cons umers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient energy
ava ilab le to start the engine .
I n tell igen t energy management in your vehi
cle hand les the d istribution of electrical ener
gy . Starting abi lity is marked ly imp roved and
the life of the battery is extended.
Int ellig ent technolog y 229
Basica lly, energy management consis ts of
batte ry diagnosi s, idling cur rent manage
ment
and dynamic energy management.
Battery diagnosis
B attery diagnosis continuously de termines
the state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Id lin g cur ren t man agement reduces energy
consumption while the vehi cle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo nents. Data from battery diagnos is is cons id
ered.
Depend ing on the battery's state of cha rge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy manag ement
While the vehicle is being driven, dynamic en
ergy management distrib utes the energy ge n
erated according to the needs of the individ u
al components. It regulates consumption, so
that more electrical energy is not being used
than is be ing generated and ensures an opti
mal state of charge for the battery .
(D Tips
-But even e nergy management cannot
negate the limits of physics. Consider
t hat the powe r and l ife of a bat tery are
l imited.
- If start ing ability is threatened, you are
informed by a warning ¢

230 Intellig ent technol ogy
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant electr ical energy is re
qu ired, but only a little is generated. It is also
cr itical if the e ngine is not running and elect ri
cal components a re turned on. In th is in
stance energy is being consumed but none is being generated .
I t is in precisely these situations that you w ill
notice energy management actively regulat
ing the distrib ution of energy.
Vehicle stand s for an ext ende d period
If you do not drive your vehicle over a period
of several days or weeks, electrical compo
nents are gradually cut back o r switched off .
This reduces energy cons umption and main
tains starting capab ility
over a longer period.
Take into consideration that when you un lock
your ve hicle, some convenience functions,
such as the interior ligh ts or the power seat
ad justmen t, may not be available. The con
venience functions will be available again
when you turn on the ignition and start the
engine.
With the engine turned off
I f you listen to the radio, for example, with
the eng ine turned off or use other MM I func
tions, the battery is being discharged .
I f sta rting capability is jeopa rdized due to en
e rgy consumpt ion, the follow ing warning ap
pears in the MMI disp lay:
Ple ase s tart engin e, otherwi se system will
s wit ch off in 3 minute s.
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 eng in e runnin g
Although e lectrical energy is gene rated when
the vehicle is being driven, the battery can be
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili brium, consumers which req uire especially
large amounts of energy are temporar ily cut
back or sw itched off. Heat ing systems in par
t icular require a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been tempora rily cut back or switched
off . These systems w ill be available again as
soon as t he energy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T h is is normal and not
a cause for con cern. By inc reas ing engine id le
speed the additional energy required is gener
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the fo llow ing driver message:
(•) low batte ry charge: bat tery w ill be
ch arg ed whil e dri ving
This notificat ion reminds you that the starting
capability of the engine may be lim ited. As
soon as you start dr iv ing again, the battery
will be recharged and the not ificat io n will go
out .
Driver notific ation app ear s a nd goe s out
again
If this driver notification appears after the ig
nition is turned on or wh ile driving and it goes
out again after a while, the battery has been
adequately recharged. .,.
Driver notification appears and does not
go out again
If this driver notification appears after the ig
nition is turned on or while driving and does
not go out again, the battery's state of charge
is not in the opt imal range. Starting ability is
restricted. Have the battery checked as soon
as poss ible by an author ized Audi dealer or
qua lified workshop.

234 Driving and en vironm ent
,8. WARNING
-Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par
t icu late filter could start a fire .
- Do not apply an underbody protectant in the exhaust system area or a fire could start.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam
aged.
This is especia lly true for vehicles with low
slung chassis (sports chassis)* and fully load
ed vehicles.
Shutting down vehicle
If you would like your vehicle to remain inop
erative for a longer period of time, contact an
Audi or other specialized dealer . They can ad
vise you on necessary precautions e.g . corro
sion prevention, maintenance and storage. Pay attention to additional information con
cerning the battery. Refer to

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 tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent . This sec
tion will give you some tips on how you can help the environment 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
dit ions, trip length, etc.
· Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac
celerating.
., Avo id unnecessary accelerating and brak ing.
Vehicles use the most fuel when they are ac
celerating . 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 examp le 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.
Accelerating gently reduces fuel consump
tion, engine wear, and does not disturb the environment.
Fuel consumption, exhaust emissions and en
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con
ditions permit.
258 Checking and filling
-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. Wait 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
th ick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- 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).
- 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 do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and chemical hazards
