Intelligent Technology
Driving with your
quattro
With all-wheel drive, all four wh eels are driven.
G eneral information
With all-whee l drive, power is distributed to all
four wheels. This happens automatically depend
ing on you r driv ing style and the road condit ions
at the time. See also¢
page 186 .
A center differentia l distrib utes the driving power
variably to the front and rear axle. It works to
gether with selective wheel torque control, which
activates when driving t hrough curves
~ page 186.
The all-wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow
erful and has excellent driving characterist ics
both under normal dr iv ing condit ions and on
snow and ice . Always read and fo llow safety pre
cautions ~
/1..
Winter tires
When driving in the winter, your vehicle with all
wheel drive has an advantage, even with regular tires. In winter road conditions it may be adv isa
b le to mount wi nte r tires (or all-season tires) for
improve d driveab ility and bra king: these tires
m ust be mounted on
all four wheel s. See also
¢ page 245, Winter tires.
Tire cha ins
Where tire chains are mandatory on certain
roads, this norma lly also applies to vehi cles w ith
all-whee l d rive ~
page 245, Snow chains.
Replacing wheels /tires
Veh icles with all-whee l dr ive must always have
tires of the same s ize. A lso avo id tires with d iffer
ent t read depths. For details see page
~ page 237, New tires or wheels.
.&, WARNING
Always adjust yo ur drivi ng to road and traff ic
c ondi tions . Do not let the extra safety afford
ed by all -wheel drive tempt you into ta king
extra risks .

-Although the all-wheel d rive is very e ffec
tive, always remember that braking capacity
is limited by tire tract ion. You shou ld there
fore not drive at excessive speeds on icy or
slippery road s urfaces.
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be
gi n to slide on top of t he water (aquapla n
ing). If th is should occur, you will h ave no
warn ing from a s udden increase i n engine
spee d as wi th a front-wheel d rive vehicle.
Always d rive at speeds which are suited to
the road conditions -risk of crash.
Energy management
· Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa
bility of electrical energy for starting the engine .
If a vehicle with a conventional energy system is
not dr iven for a long period of time, the batte ry is
discharged by id ling current consumers (e.g. im
mobilizer) . In certain c ircumstances it can resu lt
i n the re being insuffic ient energy ava ilable to
start the eng ine.
Intelligent energy management in your vehicle
handles the d istribution of elec trical energy .
Start ing ability is markedly improved and the life
of the batte ry is ex tended.
Bas ically, energy management consists of
bat
tery diagnosis , idling current man agement
and
dynamic ene rgy management .
Battery diagnos is
Battery d iagnosis continuously determines the
state of the battery. Sensors determine battery
vo ltage , battery current and battery tempera
ture . This determines the current state o f charge
and the power of the battery .
Idling current management
Idling cur rent management reduces energy con
sumption while the vehicle is standing. With the ..,.

-Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can resu lt from old or inappro
priate brake fluid. Observe these precau
t ions:
- Use only brake flu id that meets SAE speci
fication
J 1 703 and confo rms to Fede ral
Motor Vehicle Standard 116. Always check
with your author ized Audi dealer to make
sure you are using the correct brake fluid.
The correct type of brake fluid is a lso indi
cated on the brake flu id reservoir.
- The brake fluid must be new. Heavy use o f
the brakes can cause a vapor lock if the
brake fl uid is left in the system too long.
This can serious ly affect the efficiency of
the brakes as well as your safety. This
could result in an acc ident.
Brake fluid w ill damage the pa int of yo ur vehi
cle.
@) For the sake of the environment
Because of the prob lem of proper disposal of
brake flu id as we ll as the special tools re
qui red and the necessary expertise, we rec
ommend that you have the brake fluid
changed by your author ized Audi dealer.
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
W ith
high outside temperatures or long da ily
drives we recommend that you have the electro lyte level checked by an authorized Audi dea ler or
qua lified workshop. The e lectrolyte level should
a lso be checked each t ime the batte ry is charged
¢ page 22 7.
H ave the battery checked when you take your ve
hi cle in for serv ice. You a re well advised to re
p lace a batte ry that is o lde r than 5 years .
Check ing and Filling
Hybrid dr ive *: you can find important in format ion
about the high voltage battery under
¢ page 100.
Disconnecting the battery te rminals
Some vehi cle functions (power window regula
tors, for examp le) are lost if the batte ry te rm i
nals a re disconnected . These functions have to be
re learned after the battery terminals a re con
nected again. To prevent this, the battery should
only be disconnected from the vehicle electrical
system when absolutely necessary for repa irs.
Vehicles not dr iven for long p eriod s
If you do not drive your vehicle over a period of
severa l days or weeks, electrical compone nts are
gradually cut back or switched off. This reduces
energy consumpt ion and maintains starting ca
pability over a longer per iod
¢ page 192.
T ake into consideratio n that when you unlock
your vehicle, some convenience functions, suc h
as the inter ior lights or the power seat adjust
ment, may not be ava ilab le. The conve nience
funct ions will be available again when you turn
on the ignition and sta rt the eng ine.
Winter operation
D uring the winter months, battery capacity tends
to decrease as temperatures drop. This is be
cause more power is also consumed while start
i ng, and the headlights, rear w indow defogger,
etc., are used more ofte n.
Avo id unnecessary power consumption, pa rtic u
larly in city traff ic or when traveling only short
distances . Let your author ized Audi dealer check
the capacity of the veh icle batte ry before winter
sets in
¢ page 22 7. A we ll charged batte ry will
not only p reve nt start ing prob lems when the
wea the r is co ld, but will also last longer.
Working on the battery
Be especially careful when working on or near
the battery.

Checking and Filling
-Always follow the operating instructions
provided by the battery charger manufactur
er when charging your battery.
- Never charge a frozen battery . It may ex
plode because of gas trapped in the ice. Al
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen .
The battery housing may have cracked and
weakened when the battery froze .
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark . Do not smoke. Hydrogen gas generat
ed by the battery is explosive .
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charging a battery is dangerous and should only be attempted by a competent
technician with the proper equipment .
- Battery acid that may spill during charging should be washed off with a solution of
warm water and baking soda to neutralize
the acid.
(D Note
Never use a fast charger as a booster to start
the engine. This will seriously damage sensi
tive electronic components, such as control
units , relays , radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
~ page 192. The intelli
gent energy management system will keep the
engine battery charged better then vehicles with
out this system. To mak e sure the additional
electrical energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu facture only (the same as those installed at the
time your vehicle was delivered) . Specifications
228
are listed on the battery housing. Your author
ized dealer must cod e the battery in the energy
management system to enable you to use the en
ergy management functions correctly after re
placing the battery.
If it is not possible to use a battery of this type,
the new battery must have the same capacity,
voltage (12 volts), amperage, construction and plug sealing.
When installing the battery, make sure the igni
tion and all electrical consumers are turned off.
([) Note
- Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of bat
tery can cause problems in the vehicle elec
trical system. When replacing the vehicle battery, always install one with the same
specifications as the original battery.
@ For the sake of the environment
Because of the problem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat
teries contain sulfuric acid and lead and must
always be disposed of properly in compliance
with all environmental regulations. Disposing
of vehicle batteries improperly is
very danger
ous to the environment.

General
This chapter is intended for trained emergency crews and working personnel who have the nec
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con be started by con
necting it to the battery of another vehicle.
If the engine should fail to start because of a dis
charged or weak battery, the battery can be con
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in
jury. Follow the instructions below for
safe
handling of your vehicle's battery.
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables.
If you do not, this in-
266
creases the risk of an explosion and chemi
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author
ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery.
- The voltage of the booster battery must also
have a 12-Volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial
ly different "Ah" rating may cause an explo
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak
ened.
- Use of batteries of different voltage or sub
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
