A WARNING ,-
- Always look for traff ic and check the area
around your vehicle by looking at it di­
rectly as well. The parking system cannot
replace the driver 's attent ion. The driver
is always respons ible when entering or
leaving a parking space and during simi­
lar maneuvers .
- Please note that some surfaces, such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
wh ich people and objects cannot be de­
tected . Be especially cautious of small
children and animals.
- Always pay attention to the area around
the vehicle -using the rearview mirror,
too .
- The sensors can be displaced by impacts
or damage to the radiator grille, bumper ,
wheel housing and the unde rbody . The
par king system may become impai red as
a result. Have an authorized Aud i dealer
or authorized Audi Service Facility check
their function .
Parking system s 119
-Make sure the sensors are not obstructed
by st ickers, deposits or other materials.
If they are, the sensor function could be impaired. For additional information on
cleaning, refer to~
page 204 .
(D Note
-Some objects are not detected or dis­
played by the system under certain cir­
cumstances:
- Objects such as ba rrier chains, trailer
draw bars, vertical po les or fences
- Objects above the senso rs such as wall
extensions
- Objects w ith specific surfaces or st ruc­
tures such as chain link fences or pow­ der snow
- If you continue d riving closer to a low-ly­
ing object, it may disappear from the
sensor range . Note that you wi ll no lon­
ger be warned about this obstacle.
- T he sensors can be displaced by impacts
or damage to the radiato r grille, bumper,
wheel housing and the underbody. The park ing system may become impaired as
a result. Have an authori zed Audi dealer
or authorized Audi Service Facility check
their function .
{!) Tips
- The system may provide a warning even
though there are no obstacles in the cov­
erage area in some situations, such as:
- certain road su rfaces or for long grass.
- externa l ult rason ic sources e.g. from
clean ing vehicles.
- heavy ra in , snow, or thick vehicle ex­
haust.
- We recommend that you practice park­
ing in a traff ic-free location or par king
lot to become familiar w ith the system.
When doing this , the re should be good
light and weather cond itions.
- Yo u can change the vo lume and pitch of
the signals as we ll as the disp lay

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 .
Smart Technolog y 193
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 .,. •

256 Tires and wheels
loss of control, crashes and serious per­
sona l injuries . Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
l east.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q 0 . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
@ Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily .
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
@ Tips
Where snow chains are mandatory on cer­
tain roads, this normally also applies to
vehicles with all-wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right
length and correct ly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly . .,..

260 Tire s and wheel s
& WARNING
-If the tire pressure warning light ti] in
the instrument cluster turns on, the
pressure in one or more tires is too low.
Reduce the vehicle speed immediately
and avoid any hard steering or braking
maneuvers . Stop as soon as possible,
check the t ire and inflate the tire to the
correct pressure, which is specified on
the tire pressu re labe l on the veh icle
<:?page 235. Driving with a t ire with low
pressure causes the tire to overheat and
can res ult in failure of the tire . Low pres ­
sure can a lso have a negat ive effect on
the driving and braking behavior of the
vehicle.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be de layed .
- Ask your author ized dealer if r un-flat
t ires may be used on your vehicle.
- The tire pressure monitoring system can
also stop work ing when there is an ESC
malfunction.
- Using snow chains may result in a system
malfunction.
- The tires with the ident ificat ion "AO" or
"RO" ¢ page 248 have been matched
with your A udi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
on ly mon itor the t ire pressure of the
driving tires . Check the tire pressu re of
the spa re wheel in the luggage com part­
ment so tha t if ne cessary i t is ready for
u se.

Storing tire pressures
Applies to vehicles: wit h tire press ure mo nitor ing system
A change in tire pressure or a change in tires
must be stored in the system.
The tire pressure is stored in the MMI.
.. Ma ke s ure before storing that the ti re pres ­
sures of a ll four tires meet the specified va l­
ues and are adapted to the load. Otherwise
the system could malfunction
