Depending on your vehicle's equipment , various
parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 137.
The
parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the veh icle
¢ page 137.
The
rearview camera shows the area behind the
vehicle in the Infotainment system display . The
lines in the rearview camera image help you to
park or
maneuver ¢ page 138. The parking sys­
tem plus functions are also available
¢ page 137.
The
peripheral cameras give various views to
help you when parking or maneuvering
¢ page 140. The parking system plus functions
are also available
¢page 137.
A WARNING ,..__ -
- Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar 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 detect­
ed . Be especially cautious of small children
and animals .
- Always keep your eyes on the vehicle's sur ­
roundings, using the rearview mirror as
well.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park­ ing system may be impa ired as a result.
136
Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion.
(D Note
- Some objects are not detected or displayed
by the system under certain circumstances:
- objects such as barrier chains, trailer draw
bars, vertical poles or fences
- objects above the sensors such as wall ex ­
tensions
- objects with certain surfaces or structures
such as chain link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor
range. Note that you will no longer be
warned about this obstacle.
- Keep enough distance from the curb to re ­
duce the risk of damage to the rims.
{i) Tips
- The system may provide a warning even
though there are no obstacles in the cover ­
age area in some situations, such as:
- certain road surfaces or when there is tall
grass
- external ultrasonic sources such as from
cleaning vehicles
-in heavy rain, snow, or thick vehicle ex­
haust
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system . When doing
this, there should be good light and weath­
er conditions.
- You can change the volume of the signals
and the display ¢
page 143.
- Please refer to the instructions for towing a
trailer located in
¢page 144.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for the parking aid to operate .
- Th e rearv iew camera is automatically
cleaned when cleaning the rear window*

- Press the accelerator pedal ca refully when
accelerating on smooth, slippery surfaces
such as ice and snow. The dr ive wheels can
spin even when these control systems are
installed and th is can affect driving stability
and increase the r isk of a coll is ion.

Intellig ent Technology
{!) Tips
- The ABS and ASR only funct ion correct ly
when all four wheels have a sim ilar wear
condition. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de­
scribed are working.

The all-wheel drive system dist ributes the d riving
power var iably to the front and rear axle. It works
together with selective whee l torque cont rol,
which activates when driving through curves
c:> page 146. With the sport differentia l*, power
d istribution to the rear wheels is variable and can
be adjusted using the dr ive select
c:> page 134.
The all wheel drive concept is designed for high
engine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under norma l dr iving condit ions and on
snow and ice . Always read and fo llow safety pre ­
cautions
c:> .&. .
Winter t ires
By us ing all wheel drive, yo ur vehicle has good
forward motion with standard tires in w inte r con­
d itions. However, using winter or all season tires
on
all four wheels in the winter is recommended ,
because this will improve the
braking effec t.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:> page 350, Snow chains .
Replacing tire s
For vehicles with all whee l drive, only whee ls with
the same ro lling circumference s hou ld be used.
Avoid using tires w ith different tread depths
c:> page 341, New tires or wheels.
Offroad vehicle?
The ground clearance is too low on some mode ls
to drive on rough terrain. Therefore, avoid off­ road trips.
A WARNING
-Also, in vehicles with a ll w heel d rive, adapt
your dr iv ing style to the current road and
t raff ic conditions . Do not let the increased
safety provided tempt you into tak ing risks,
because t his increases the r is k of an acci­
dent .
Intellig ent Technology
- The braking ab ility o f your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle . Do not be tempted to accelerate to a
h igh speed whe n the road is sli ppery, be­
cause this i ncreases the risk of an accident.
- No te that o n wet streets, the fron t wheels
can "hydrop la ne" if dr iv ing at speeds that
are too high. Unlik e front wheel d rive
veh icles, the engine does not rev h ig her sud­
denly when the vehicle begins hydrop laning.

road conditions to re duce the risk of an acci­
dent .
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine .
When a vehicle with a conventional energy sys­
tem is not drive n for a long time, the ve hicle bat­
te ry is d rained by equipment (for example, t he
immob ilizer). In certa in circ ums tances , there
c ou ld m ay no t be eno ugh e nergy to start the en­
gine.
You r vehicle is equi pped with an in tell igent ener­
gy manageme nt system fo r dist ributing electrici­
ty. This sig nifican tly improves the start ing ability
and in cre ase s t he vehicle battery life.
The ene rgy ma nagement system Is made up of
battery diagnosi s, idling current management ,
and dynamic energy management .
Battery diagnosis
The battery diagnos is determines the vehicle bat­
te ry c harge level. The sensors determine the bat ­
te ry vo ltage, the batte ry cu rrent, and the batte ry
temperat ure. The current c ha rge level and t he
perfo rman ce of the vehicle battery a re de ter-
mine d base d on this.

the risk of a n acc ident beca use it can cause
the tire to burst.
- Always adapt your driving to the road and
traff ic conditions. Drive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose traction on b lack ice.
@ For the sake of the environment
Reinstall summe r tires at the approp riate
time, because they provide better hand ling
when roads are free of snow and ice. S ummer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries w here w inte r ti res are req uired, only
w inter t ires with the
& symbol may be per ­
m itted.
Snow chains
Snow ch ains not only i mprove the d riving in win ­
t er ro ad cond itions, b ut also the brak ing.
... Only insta ll snow chains o n the front wheels .
T h is applies also to ve hicles w ith all wheel
drive* .
... Check an d cor rect the sea ting of the snow
c h ains a fte r dr iv ing a few feet, i f necessary. Fo l­
l ow the instructions from the manufacturer .
... Note the maximum permitted speed when d riv ­
ing with snow chains . Do not exceed 30 mp h
(SO km/h).
Use of snow chains is on ly pe rmitted with certain
rim/t ire combinations due to technical reasons.
Check with an authorized Audi dealer o r autho r­
ized Aud i Service Fac ility to see if yo u may use
snow chains.
Use
fine -mesh snow chains . They must not add
more t han 0.53 in (13.5 mm) in height, includ ing
the chain lock .
You must remove the snow c hains on roads wit h­
out snow. Othe rw ise, you could impa ir dr iv ing
ab ility and damage the tires.

A WARNING ~
Using incorrect snow chains or installing snow
cha ins i ncor rectly can result in loss of veh icle
con trol, which increases the risk of a n acci­
d ent.
(D Note
Snow chains can damage the rims/whee l cov­
e rs* if the chains come into direct contact
wi th them . Remove the whee l covers* first.

Low-profile tires
Applies to: vehicles with low-profile tires
Your vehicle is equip ped wi th low -profi le t ires* at
t h e factory. Compa re d t o o ther tire/r im com bina ­
tions, low -profi le tires offer a w ider tread surface
and a larger rim diameter with shorter tire side­
walls . This results in an agile dr iv ing style. How­
ever, it may reduce the leve l of com fort and in­
crease road noise whe n driving on roads in poor
cond it ion.
Low-p rofile ti res can become damaged mo re
q uick ly than standard tires when dr iv ing ove r
l a rge bumps, potholes, manhole covers, speed
bumps and curbs . Therefore, it is particularly im­
po rtan t to maintain the correct tire pressure
<:;> page 344.
To reduce the risk of damage to the tires and
rims, drive very caref ully on poor roads.
Check your wheels regu larly eve ry 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims .
After a heavy impact o r damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dea ler or authorized Audi
Service Facility .

several minutes after storing the pressures until
the indicator light turns off . If the indicator lig ht
does turn off or turns on aga in after a short peri­
od of time, drive to an authorized Audi dealer or
author ized Audi Service Facility immed iately to
have the ma lfunction corrected .
A WARNING
-If the t ire pressu re indica tor appea rs in the
display, red uce your speed immed iate ly and
avoid any har d st eer ing or braking maneu­
vers. Stop a s soon as possib le and check the
ti res and their press ure.
- T he driver is responsi ble for main taining the
cor rect ti re pressure. You must check the
tire pressure regu larly .
- Under certa in conditions (s uch as a sporty
driving style, winte r cond itio ns or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.
(D Tips
- The t ire press ure monitoring sys tem can al ­
so stop work ing when there is an ESC mal ­
funct ion .
- Usin g snow chains may result in a system
malfunction.

compact spare tire . The compact spare tire has
been designed specifically for your type of vehi­
cle. Do not replace it with the spare tire from an­
other type of vehicle.
The compact spare tire is located in the luggage
compartment under the cargo f loor cover
c::>page360.
The tire pressure must be 61 PSI (420 kPA).
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive with snow chains and a front
tire fails, mount the spare t ire in place of a rear
tire. Install the snow chains on the rear tire that
you removed, and insta ll that in place of the
front tire that failed.
A WARNING
-After installing a spare tire, the tire pres­
sure must be checked as soon as possible.
-Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
-T o reduce the risk of an accident, avoid full­
thrott le acceleration, heavy braking, and
fast cornering with the compact spare tire.
-To reduce the risk of an accident, never drive
with more than one compact spare tire.
-Normal summer or winte r tires must not be
mounted on the compact spare wheel rim.
