Winter tires
By using all wheel drive, yo ur vehicle has good
forward motion with standard tires in winter
conditions. However, in winter we recommend
using winter or all season tir es on
all four
wheels, because this will imp rove the broking
effec t.
Snow chains
If there are snow chain laws, snow chains
must also be used on vehicles with a ll whee l
drive ¢
page 256, Snow chains .
Replacing tires
For vehicles w ith all wheel dr ive, only wheels
with the same rolling circumference should be
used . Avoid wheels with different tread
depths ¢
page 248.
Offroad vehicle?
Your Audi is not an offroad veh icle -there is
not enough ground clearance. For t his reason,
avoid difficult terrain. Refer to ¢
page 280.
.&_ WARNING -
-Also , in vehicles with all whee l drive,
adapt your driving style to the current
road and traff ic conditions. Do not let
the increased safety provided tempt you
into taking risks.
- The brak ing ability of your vehicle is lim­
ited to the traction of the wheels . In this
way, it is not different from a two wheel dr ive vehicle. Do not be tempted to ac­
celerate to a h igh speed when the road is
slippery th is increases the risk of an acci­
dent.
- Note that on wet streets, the front
wheels can "hydroplane" if driving at
speeds that are too high. Unlike front
wheel drive vehicles, the engine does not
rev higher suddenly when the vehicle be­
gins hydroplaning. For this reason, pay
attention to the road conditions regard­
less of your speed .

Energy management
The starting ability is optimized
The energy management system manages
the electrical energy distribution and optimiz ­
es the availability of electrical energy for
starting the engine.
When a vehicle with a conventional energy
system is not driven for a long time , the bat­
tery is drained by equipment (for example the
immobilizer). In certain circumstances, there
could may no t be enough energy to start the
engine .
Your vehicle is equipped with an intelligent
energy management system for distr ibut ing
electric ity. This significantly improves the
starting ability and increases the battery life.
The energy management system Is made up
of
battery diagnosis , idling current manage­
ment
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the battery
charge level. The sensors determine the bat­
tery voltage, the battery current, and the bat­
tery temperature. The current charge leve l
and t he performance of the battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off, it manages the energy distribu­
tion to the different elect rical components.
Date from battery diagnosis is taken into ac ­
count for this.
Depend ing on the battery charge leve l, elec­
trical equip ment is switched off one item after
the other, to prevent the battery from drain­
ing and to retain the starting ability.
Dynamic energy management
While driv ing , dynamic energy management
distributes the appropriate amount of energy
to the e lectr ica l equipment . It controls the
battery charge level so that more energy is .,. •

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

- When working on the battery , be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury .
- Always keep the battery well out of the reach of children .
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca ­
ble .
- Before performing any work on the elec ­
trical system , switch off the engine and
ignition as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected. If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables - this could start a fire!
- Never charge a fro zen or a thawed-out
battery. It could explode! If a battery has
fro zen, then it must be replaced. A dead
battery can freeze over at 32°F (O°C) .
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery .
- Never use batteries which are damaged.
There is the danger of an explosion ! Al­
