Snow cha in s
Where t ire cha ins are mandatory on certain
roads, this normally a lso applies to vehicles
with a ll-wheel drive ¢

chains .
Replacing wheels /t ir es
Vehicles with all-wheel drive must a lways
have tires of the same size. Also avoid t ires
with different tread depths. For details see
page ~
page 207, New tires and replacing
tires and wheels.
Off -Ro ad dri ving?
Your Aud i does not have enough ground clear­
ance to be used as an off -road veh icle.
It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
¢ page 160.
A 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
taking extra r isks.
- Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by t ire traction . You
should the refore not dr ive at excessive
speeds on icy or slippery road su rfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning) .
If this should occ ur, you
will have no warning from a sudden in ­
crease in engine speed as with a front­
wheel drive vehicle. A lways drive at
speeds wh ich are suited 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 conventional energy system
is not driven for a long per iod of t ime, the bat­
tery is discharged by idling current consumers (e .g. immobilize r). In certa in circumstances it
can resu lt in the re be ing insufficient energy
available to start the engine.
Intelligent energy management in your vehi­
cl e handles the distribution of e lectr ica l ene r­
gy . Start ing ability is ma rkedly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
b att ery diag nosis, idlin g curre nt manage ­
m ent
and dynamic en erg y manag em ent .
Battery di agnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature. This determines the current state o f charge and the power of the battery .
Idling current managem ent
Idling current management reduces energy
consumption while the vehicle is standing .
With the ig nition sw itched off, it controls the
energy supply to the various electri ca l compo ­
nents. Da ta from ba ttery diagnos is is cons id ­
ered.
Depend ing on the batte ry's state of cha rge,
individual cons ume rs a re g radually turned off
to prevent excessive discharge of the battery
and th us maintain starting capability.
Dynamic energ y manag ement
While the vehicle is being driven, dynamic en­
ergy ma nagement distr ibutes the energy gen­
era ted accord ing to t he needs of the individ u-
al components .
It regula tes consumption, so
that more electrical energy is not being used ..,.

This reduces energy consumption and main­
tains starting capability over a longer period

page 156. Some of the convenience func­
tions may not operate, such as the interior
lights or power seat adjustment. The conven­
ience functions will be ava ilable again when
you switch on the ignition and start the en­
g ine .
Winte r oper ati on
During the winter months, battery capacity
tends to decrease as temperatures drop. This
i s because more power is also consumed while
start ing, and the headlights, rear window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short distances . Let your authorized Audi
dealer check the capac ity of the vehicle bat­
tery before winte r sets inc::>
page 193. A we ll
charged ba tte ry w ill no t only prevent starting
prob lems when the weathe r is cold, but will
a lso last longer .
Replacing battery
The new battery must have the same capaci­
ty, vo ltage ( 12 volts), amperage, cons truction
and p lug sealing, as the origina l ba tte ry. Spec­
if ications are listed on the batte ry housing.
Batteries specially developed by A udi fulfill
the maintenance, output, and safety require­
ments.
When insta lling the battery, make sure the ig ­
nition and all electrica l cons umers are switch­
ed off c::>
(i).
We recommen d that yo u use ma intenance­
free or
cy cle- re sis tant /leak-pr oof batteries
according to the standards TL 825 06 (from
April 2008) and VW 7 SO 73 (from Apri l
2010).
Replacing the batte ry should be carried by a
q ua lified workshop. P lease follow the instruc­
tions on the battery cover.
Checkin g and fillin g 191
@ Note
-All work on the battery requires techni­
cal know ledge. Please contact an Audi
dealership or another authorized fac ility
for questions about the battery - danger
of 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 luggage com­
partment cannot leak, because the elec­
t ro lyte for this batte ry is abso rbed into a
special glass mat. This lea k-proof battery
must not be replace with a convent iona l
bat tery.
- Make su re the ventilation hose on t he
side of the ba ttery is connected, othe r­
w ise fumes or battery ac id can leak out.
- Batte ry holder and termin als always
have to be sec ured correc tly.
- Before all work on the batte ry follow the
warning s below c::> .&. in Working on the
battery on page
192 .
@ For the sake of the environment
Because of the p rob lem of proper disposal
of a ba ttery, we recommend your author­
i zed Audi dealer change the bat tery fo r
you. Batteries contain sulfuric acid and l ead and must always be disposed of prop ­
erly in comp liance with a ll environmental
regulat ions. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi­
ro nment. Make sure that the removed bat­
tery cannot overbalance, othe rwise sulfu­
r ic acid might escape!
@ Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery shou ld be removed and
stored w here it w ill not freeze. This will
p revent it from be ing dam aged and h aving
to be replaced .

194 Checking and filling
When charging at low voltages (e.g . w ith a
tri ckle charger ), the battery cables do not
have to be d isconnected first. Be fore charging
at
high voltages, i.e. " fast charging ", you
must disconnect both cables. In e ither case,
follow the instruct ions from the ma nufacturer
of the charger .
