tioni ng properly, contact your a uthorized
Audi dealer immediate ly.
Driving with your
quattro
App lies to vehicles: with a ll-wheel drive
With all-wheel drive, all four wheels are driv­
en.
Gene ral inform ati on
With all-wheel drive, power is distributed to
all four wheels. This happens automatically
depending on your dr iving sty le and the road
conditions at the t ime. See a lso
r=;, page 142.
The all-wheel drive concept is designed for
h igh engine power. Your vehicle is exception­
ally powerful and has excellent dr iving charac­
ter istics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions
c::;, ,&. .
Winter t ire s
When drivi ng in the w inter, your ve hicle w ith
all-wheel drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter t ires (or all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
a ll f our
w heel s.
See also c::;, page 196, Winter tires.
Snow chains
Where t ire cha ins are mandatory on certain
roads, th is normally a lso applies to vehicles
w ith a ll-wheel d rive
c::;, page 19 7, Snow
chains .
Replacing wheels /tire s
Vehicles w ith all-wheel drive must always
have tires of the same size. Also avoid t i res
with d iffe ren t tread depths. For details see
page
c::;, page 192 , New tires and replacing
tires and wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road veh icle.
It is
Int ellig ent technolog y 147
therefore best to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to
r=;, page 151.
_& WARNING
Always adjust your dr iv ing to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire tract ion. You
should t herefore not d rive at excessive
speeds on icy or slippe ry road s urfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning) . If th is should occur, yo u
wi ll have no warning from a s udden in ­
crease in engine speed as with a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
ditions. -risk of crash.
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 conventiona l energy system
is not d rive n for a long per iod of t ime, the bat­
te ry is discharged by idling current consumers
(e.g . immobilizer). In certain circumstances it
can res ult in there being insufficient energy
available to start the eng ine.
Intellige nt energy managemen t in your vehi­
cle handles the dis tribution o f electrica l ene r­
gy. Starting ability is marked ly improved and
the life of the battery is extended .

176 Check ing and filling
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than S years .
Disconn ect ing the battery terminals
Some veh icle functions (power w indow regu­
lators, for example) are lost if the battery ter ­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be d isconnected from the vehicle
electr ical system when absolutely necessary
for repairs .
V ehicles not dri ven for l ong period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­ nents are gradually cut back or switched off .
This reduces energy consumption and main­ tains starting capab ility over a longer period
c:::>
page 147. Some of the convenience func­
tions may not operate, suc h as the inte rior
l ights or power seat adjustme nt. The conven­
i ence functions wi ll be ava ilable aga in whe n
you switch on the ignition and start the en ­
gine.
Winter operati on
During the winter months, batte ry capacity
tends to decrease as tempe ratu res d rop . This
is because more powe r is also consumed while
start ing , and the headlights, rea r window de ­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when t rave ling on ly
short distances. Let you r authorized Aud i
dea ler check the capacity of the vehicle bat ­
tery before winter sets inc:::>
page 179 . A we ll
charged battery w ill not only prevent starting
prob lems when the weather is cold, but will
a lso last longer .
Replacing battery
The new battery must have the same capaci­
ty, vo ltage (12 volts), amperage, construction
and p lug sealing, as the origina l battery. Spec­
if ications are listed on the battery housing.
Batteries specially developed by Audi fulfill the maintenance, outp
ut, and safety require­
ments .
When install ing the battery, m ake su re the ig­
ni tion and a ll ele ct rical consumers are switch ­
ed off

We recommend that you use maintenance­
free or
cy cle-re si stant /leak -proof b atter ies
accord ing to the s tanda rds TL 825 06 (from
Apri l 2008) and VW 7 SO 73 (from April
2010) .
Rep lac ing the bat tery shou ld be car ried by a
qualified wo rkshop. Please fo llow the instruc­
tions on the battery cover .

for questions abo ut the batte ry -danger
o f ac id burns and exp losion hazard!
- The battery must not be opened! Do not
try to change the battery's liquid level,
otherwise detonating gas will escape
from the battery - explosion hazard!
- The AGM battery in the l uggage com­
partment cannot leak, because the elec­
tro lyte for this battery is absorbed into a
special glass mat. This leak-proof battery
must not be replace with a convent ional
battery.
- Make sure the ventilation hose on the
side of the battery is connected, other­
w ise fumes or battery ac id can leak out .
- Batte ry holder and termina ls always
have to be secured correctly .

@ For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recommend your author­
iz ed Audi dealer change the battery for
you. Batteries contain sulfur ic acid and
l ead and must a lways be disposed o f prop-
erly in compliance wi th al l envi ronmental ..,.

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary 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 can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
g ine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to safely carry the starter
current. Refer to the manufacturer's specifica­
tions.
Use only jumper cables which have
insulated
termina l clamps and are properly marked for
distinction :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
_& WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield you r eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 21 7
-A discharged battery can already freeze
at temperatures just below 32 °F (0 °C).
Before connect ing a jumper cable, the
frozen battery must be thawed com­
pletely, otherwise it could explode .
- 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 batter ies generate explosive gas­
es. Keep sparks, flame and lighted c iga­
rettes away from batteries.
- Do not try to jump start any veh icle w ith
a low ac id 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 bat­
tery. Use of batteries of diff erent voltage
or substantially different "Ah" rat ing
may cause an exp losion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen . The battery case may have
be weakened.
- Use of batter ies of different voltage or
substantially different capacity (Ah) rat ­
ing may cause an exp losion and injury .
The ca pa city (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c::;,page 165, Working in the
engine compartment.
(D Note
- App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sit ive electronic components, such as
control units, relays, rad io, etc .
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
posit ive(+) terminals are connected. ..,. •
