The vehicle setup in each mode depends on the
veh icle's features . However, the engine and
steer ing are always affe cted.
E ngine and automatic tr an smi ssi on
Depending on the mode, the engine and auto­
matic transmiss ion respond more qu ickly or in a
more balanced manner to accelerator pedal
movements .
Adaptive damper s (Audi m agnetic ride )*
The adaptive dampers use sensors to record in­
formation regarding steering movements, brak ­
ing and accelerat ion operat ions by the driver,
road surface, driving speed, and load. With dr ive
select, you can adjust the adaptive dampers to
sporty (dynamic), comfortable (comfort) or ba l­
a nced (auto).
Stee ring
The power steer ing adapts . Indirect steering that
moves eas ily as in comfort mode is especially
suited to long drives on a highway. The dynam ic
mode provides sporty, direct steering.
Torque distribution
The sport d ifferent ial d istr ibutes the dr ive power
to the rear axle based on the situation . The distri­
bution of power varies depend ing on the selected
mode from mode rate
( Comfort ) to sporty ( D y­
nami c). The goal is a high leve l of agility and ab il­
ity to acce lerate o n curves . The vehicle is very re­
sponsive to steering.
Engine sound *
The engine sound adapts to the current mode
and can be subtle to sporty.

Depending on your vehicle's equipment , various
parking aids will help you when parking and ma­
neuvering.
The
rear park ing system is an audible parking aid
that warns you of obstacles
behind the vehicle
c:> poge 83.
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
c:> poge83.
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
c:> page 84. The parking sys­
tem plus functions are also available
c:> page83.
& 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 .
- The sensors can be displaced by impacts or
damage to the radiator gr ille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion .
- 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, see
c:> page266.

(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 th is obstacle.
- Keep enough distance from the curb to re­
duce the risk of damage to the rims .
@ 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.
- What appears in the display is slightly de-
layed.
- The sensors must be kept clean and free of
snow and ice for park aid to operate .

Rear parking system
Description
Applies to: vehicles with rear parking system
The rear parking system is an audible parking
aid .
Descrip tion
There is a sensor in the rear bumper cover. If
these detect an obstacle, audible signals warn
you .
Make sure the sensors are not covered by stick­
ers, deposits or any other obstructions as it may
impair the sensor function. For information on
cleaning, see
¢page 266.
The range at which the sensors begin to measure
is approximately:
side 3 ft (0 .90 m)
rear
center 5.2
ft (1.60 m)
The closer you get to the obstacle, the shorter
the interval between the audible signals . A con­
tinuous tone sounds when the obstacle is less
than approximately 1 foot (0.30 meters) away. Do not continue backing up
c:::;, &. in General infor­
mation on page 82,

on page 82!
If the distance to an obstacle remains constant,
the volume of the distance warning gradually drops after about four seconds (this does not ap­
ply in the continuous tone range).
Act ivat in g
The rear parking assist activates automatically
when the reverse gear is engaged. A brief confir­
mation tone will sound.

A WARNING
-
Driving at higher speeds without the rear
spoiler deployed can impair handling charac­ teristics, making the vehicle harder to con ­
trol.
- Always make sure that the spoiler is de­
ployed when driving at speeds over 85 mph
(140 km/h). If the rear spoiler warning/indi­
cator light in the instrument cluster comes
on, the rear spoiler may not have deployed.
- Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed .
Have the spoiler inspected as soon as possi­
ble by an authorized Audi dealer or qualified
workshop.
- Always obey speed limits and other traffic
laws.
A WARNING t =
Improper operation of the rear spoiler can
cause crushing injuries.
-
- Always make sure that nobody, especially
children, is in the way when the rear spoiler
is deployed or retracted.
(D Note
- Never push on the vehicle on the rear spoil­
er. This could cause damage.
- To prevent damage to the rear spoiler do
not lean or place anything on it.
- Only operate the rear spoiler manually when
the luggage compartment lid is close and
the rear spoiler moving parts are not
blocked. Otherwise, damage could occur.
@ Tips
Clean the rear spoiler compartment every 2 to
3 months. To function correctly, the rear
spoiler must be free of ice , snow and leaves.
Intelligent Technology
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
engtne.
When a vehicle with a conventional energy sys­
tem is not driven for a long time, the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certain circumstances , there
could may not be enough energy to start the en­
gine.
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat ­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle 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 distribution
to the different electrical components. Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from draining and to maintain the starting ability.
Dynamic energy management
While driving , dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment.
It controls the battery
charge level so that the amount of energy is not ..,_

•Pullon the belt to make sure that it is securely
latched in the buckle.
A WARNING
Improperly positioned safety belts can cause
ser ious personal injury in an c1ccident.
- Expectant mothers must always wear the
lap portion of the safety belt as low as pos­
sible across the pelvis and below the round­ ing of the abdomen .
- Always read and heed all WARNINGS and
othe r important information

Improperly worn safety belts
Incorrectly positioned safety belts can cause se­
vere injuries.
Wearing safety belts improperly can cause seri­
ous injury or death. Safety belts can only work
when they are correctly posit ioned on the body .
Improper seating positions reduce the effective­ ness of safety bel ts and w ill even increase the
risk of inju ry and death by moving the safety be lt
to criti cal areas of the body . Imprope r seating
positions also increase the risk of serious injury
and death when an airbag dep loys and strikes an
occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all
vehicle occupants and especially for children.
Therefore:
• Never pe rm it anyone to assume an incor rect
seated position in the vehicle while traveling
<=> _& .
A WARNING
Improperly worn safety belts increase the risk
of ser ious perso nal injury and death whenever
a veh icle is being used .
- Always make sure that all veh icle occupants
are correctly restrained and stay in a correct
seated posit ion wheneve r the ve hicle is be­
ing used.
- Always read and follow a ll WARNINGS and
other impo rtant informat ion

- lways make sure that the safety belt upper
anchorage is beh ind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly pos i­
tioned.
-Always make sure that there is nothing on the front passenger seat that w ill cause the
c apacit ive passenger detection system in
the seat to signa l to the Airbag Sys tem tha t
the seat is occupied by a person when it is
not, or to signa l that it is occ upied by some ­
one who is heavier than the person actua lly
sitting on the seat . The p resence of addi­
t ional objects could cause the passenger
front airbag to be turned on when it shou ld
be off, or could cause the airbag to work in a
way that is different from the way it would
have worked witho ut the object on the seat.
- Make sure that the

Advanced Airbag System components
The front passenger seat in yo ur vehicle has a lot
of
very important parts of the Advanced Airbag
Sys tem in it . These pa rts in cl ude the capacitive
passenger detection system, w iring, brackets,
and mo re. The control un it monitors the system
on the front passenger seat when the ign ition is
switched on and turns the airbag indicator light
on when a malfunct ion in the one of the system
components is detected
c::> page 208 . Because
the fro nt passenger seat contains important
pa rts of the Advanced Airbag System, you must
take ca re to preven t it from being damaged.
D amage to the seat may p revent the Advanced
Ai rbag System for the front passenger seat from
doi ng its job i n a crash.
The front Advanced Airbag System consists
of the follow ing :
- C rash sensors in the front of the vehicle that
measure vehicle accelerat ion/dece leration to
Airb ag sys tem
provide information to the Advanced A irbag
System about the severity of the cras h.
- An elect ronic contro l unit, with integrated
cras h sensors for front and side impacts . The
control un it "decides" whether to fire the front
airbags based on the information rece ived from
the crash sensors . The control unit also "de­
cides" whether the safety belt pretensioners
should be activated.
- An Advanced A irbag w ith gas generator for the
driver inside the steeri ng wheel hub .
- An Advanced A irbag w ith gas generator inside
the instrument panel for the front passenger.
-A capacit ive passenger detection system under­
neath the front passenger seat
cover. This sys­
tem measures the e lectr ica l capacitance of the
person in the seat. The information registered
is sent continuously to the elect ronic contro l
un it to reg ulate dep loyment of the front Ad­
vanced Airbag on the p assenger side.
- An airbag monitoring system and indicator
light
El in the inst rument cl uste r.
- A sensor in each front seat registe rs the d is­
t ance betwee n the respective seat and the
steer ing whee l o r ins trumen t pa nel. The infor­
mat ion registered is sent con tinuous ly to the
electronic contro l unit to regu late dep loyment
of the front Advanced Airbags .
- The
PASSENGER AIR BAG OFF~; lig ht comes
on and stays on in the headliner
c::> poge 208,
fig. 166 and tells you when the front Advanced
Airbag on the passenger side has been turned off.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety be lt is latched or not and
transmits this information to t he electronic
cont rol un it .
A WARNING
Damage to the front passenge r seat can pre­
vent the front airbag from working prope rly.
- Imp roper repair or d isassembly of the front

safety and heed the WARNINGS in this chapter.
Dep loyment of the Advanced Airbag System and
the act ivat ion of the safety belt pretensioners de­
pend on the deceleration measured by the crash
sensors and registered by the electronic control

vehicle or object invo lved in the c rash .
On the passenger side, regardless of safety belt
use, the front passenger frontal airbag w ill be
turned off if the electrical capac itance measured
by the capacit ive passenger detection system on
the fro nt passenger seat is less than the amount
p rogr ammed in the elect ronic control uni t. The
front passenger fronta l airbag will also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the child seats
that was used to certify the Advanced Airbag Sys­
tem under Federal Motor Veh icle Safety Standard

& WARNING
T o red uce the risk of i njury when an a irbag in­
flates, a lways wear safety belts proper ly .
- If you are unrestrained, lean ing fo rw ar d, s it­
t ing s idew ays or o ut o f pos ition in any way,
your risk of i nju ry is much higher.

More important things to know about front
airbags
Fig. 165 I nflated fro nt ai rbags
Safety be lts are impo rtan t to he lp keep front
seat oc cupants in the proper seated position so
that airbags can unfo ld properly and prov ide s up­
pleme nta l protection i n a fronta l co llision .
The front airbags are designed to provide addi­
t iona l protec tion fo r the chest and face of the
driver and the fron t seat passenger whe n:
- safety belts are worn properly,
- the seats have been positioned so that t he oc-
cupant is properly seated as far as possible
from the a irbag .
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have
placed on the seat could become dangerous pro ­
ject iles, and be pushed into you if the a irbag i n­
flates.
When an airbag deploys, fine dust is released.
This is norma l and is not caused by a fire in the
vehicle . This dust is made up mostly of a powder
used to lub rica te t he a irbags as they deploy.
It
cou ld irritate skin.
It is important to remembe r that wh ile the sup ­
pleme nta l airbag system is designed to reduce
the likelihood of serio us inj uries, othe r injuries,
for example swelling, bru is ing and minor abra­
s ions, can also happen when a irbags inflate . Air­
bags do not prote ct the arms or the lower p arts
of the body. Front airbags supp lement the three
point safety belts on ly in some frontal collisions
in which the vehicle dece leration is high enough
to deploy the airbags.
