Parking systems
General information
Appl ies to vehicles: with rea r parking sys te m s/park in g
syste m plus/rearv iew camera
Depending on your vehicle's equipment, vari­
ous parking aids will help you when parking
and maneuvering.
The
rear parking system is an audible parking
aid that warns you of obstacles
behind the ve­
hicle
¢ page 119.
The parking system plus assists you when
parking by audibly and visually indicating ob­
jects detected
in front of and behind the vehi­
cle
¢ page 119.
The rearview camera shows the area behind
the vehicle in the MMI display . This display as­
sists you when you are cross or parallel park­ ing. The parking system plus functions are al­
so available ¢
page 120.
& WARNING
-Always look for traffic and check the area
around your vehicle by looking at it di­
rectly as well. The parking system cannot
replace the driver 's attention. The driver
is always responsible 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
which 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 underbody. The
parking system may become impaired as
a result . Have your authorized Audi deal­
er or authorized service facility check
their function . -
Make sure the sensors are not obstructed
by stickers, deposits or other materials.
If they are, the sensor function could be impaired. For additional information on
cleaning, refer to¢
page 205.
(D Note
- Some objects are not detected or dis­
played by the system under certain cir­
cumstances:
- Objects such as barrier chains, trailer
draw bars, vertical poles or fences
- Objects above the sensors such as wall
extensions
- Objects with specific surfaces or struc­
tures such as chain link fences or pow­
der snow
- If you continue driving closer to a low-ly­
ing object, it may disappear from the
sensor range. Note that you will no lon­
ger be warned about this obstacle.
- The sensors can be displaced by impacts
or damage to the radiator grille, bumper,
wheel housing and the underbody. The
parking system may become impaired as
a result. Have your authorized Audi deal­
er or authorized service facility check
their function .
(D 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 surfaces or for long grass.
- external ultrasonic sources e.g. from
cleaning vehicles.
- heavy rain, snow, or thick vehicle ex­
haust.
- We recommend that you practice park­
ing in a traffic-free location or parking
lot to become familiar with the system.
When doing this, there should be good
light and weather conditions.
- You can change the volume and pitch of
the signals as well as the disp lay

194 Smart Technology
Winter tires By using all wheel drive, your vehicle has good
forward motion with standard tires in winter
cond itions. However, in winter we recommend
using winter or all season tires on
all four
wheels, because this will improve the braking
effect .
Snow chains
If there are snow chain laws, snow chains
must also be used on vehicles with all whee l
drive ¢
page 262, Snow chains .
Replacing tires
Fo r vehicles w ith all whee l dr ive , only wheels
with the same rolling circumference should be
used . Avoid whee ls with different tread
depths ¢
page 254.
Offroad vehicle?
Your Aud i is not an offroad vehicle -there is
not enough ground clearance. For this reason,
avoid difficult terrain. Refer to¢
page 287.
&_ WARNING
- Also, in vehicles with all whee l dr ive,
adapt yo ur driving style to the current
road and traffic conditions. Do not let
the increased safety provided tempt you
into taking risks.
- The braking 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 high speed when the road is
slippery this 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 hydroplan ing. 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 equ ipment (for example the
immobilizer). In certain circumstances, there
could may not be enough energy to start the
engine .
Your vehicle is equipped with an intel ligent
energy management system for d istr ibut ing
electricity. This s ignificantly improves the
sta rting ability and increases the battery life.
The energy management sy stem Is made up
of
battery diagnosis , idling current manage·
ment
and dynamic energy management .
Battery diagnosis
The battery d iagnosis determ ines the battery
charge leve l. The sensors determine the bat­
tery voltage, the battery current, and the bat­
tery temperature. The curren t cha rge leve l
and the performance of the battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used wh ile parked. With the engine
switched off, it manages the energy distribu­
tion to the different elect rical componen ts.
Date from battery diagnosis is taken into ac­
count for this.
Depending on the battery charge level, elec­
trical equip ment is switched off one item after
the o ther, to prevent the battery from drain­
ing and to retain the starting ability.
Dynamic energy management
While driving, 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 ..,.

loss of control, crashes and serious per­
sona l injuries. Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
wh ich 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 r is ks. A l­
ways remember:
- When brak ing, an a ll-wheel d rive vehicle
hand les in the same way as a front drive
vehicle .
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
canno t he lp under blac k ice condit ions.
@) For the sake of the environment
Use summe r tires when weathe r cond i­
tions perm it. They are quieter, do not wea r
as quickly and red uce f ue l cons umption.
Snow chains
Snow chains may be fitted on ly to the front
wheels, and only to certain tire sizes . Ask you r
authorized Audi dealer on which tire sizes
snow chains can be used.
I f you are going to use snow chains, then you
must install them on the front wheels at
l east.
The snow chains must h ave low-profi le links
and must not be thicker than 0 .53 inch
(13 .5 mm), including the lock.
Remove wheel ce nte r covers a nd tr im dis cs
be fore putting snow chains on yo ur vehicle
q0 . For sa fety reasons cover caps must then
be fitted over the whee l bolts. These are avai l­
ab le from authorized Audi dea lers.
A WARNING
Using the wrong snow chains for your veh i­
cle o r instal ling them incorrect ly can in­
crease the risk of loss of cont ro l leading to
se rious pe rsonal injury .
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions p rov ided by t he snow cha in
manufac turer.
- When driving with snow cha ins never
d rive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
@ Note
- Remove snow chains before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wea ring the snow
chains dow n un necessa rily .
- Snow chains, which come into direc t con­
tact with the whee l rim, can scrat ch or
damage it. Therefo re, make sure that the
s now chains are s uitably covered. Check
t he pos ition of t he snow chains after
driving a few yards and correct if neces ­
sary. Follow the inst ructions from the
snow chain man ufacturer when do ing so.
@ Tips
Where snow chains are mandatory on cer ­
tain roads, th is normally a lso applies to
vehicles with a ll-wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of w heel bol ts is matched to the
f ac tory installed rims. If different rims are fit­
ted, the co rrect wheel bo lts with the right
l ength and correctly shaped bolt heads must
be used. Th is ensures that wheels are fitted
securely and that the brake system functions
correct ly . .,..

266 Tire s and wheels
& 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 label on the veh icle
¢ page 240. Driving with a t ire with low
pressure causes the tire to overheat and
can result in failure of the tire . Low pres ­
sure can a lso have a negative 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 conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed .
- Ask your author ized dealer if run-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 identification "AO" or
"RO" ¢ page 254 have been matched
with your Audi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
only mon itor the t ire pressure of the
driving tires . Check the tire pressure of
the spare wheel in the luggage compart­ ment so that if necessary it is ready for
us e.
-
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.
.. Make sure before storing that the tire pres ­
sures of a ll four tires meet the specified va l­
ues and are adapted to the load. Otherwise
the system could malfunction
¢ page 240.
.. Switch on the ignition.
.. Select: the
I MENU I button >Car > Systems*
control button > Service & control > Tire
pressure monitor > Store tire pre ssure >
