Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
I n certain cases, a vehicle will be classified as
cr itica l for a la ne change even if it is still some­
what far away . The faste r a vehicle approaches,
the sooner the display in the exterior mirror will
turn on.
@ Vehicles traveling with you
Veh icles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
are indicated by the time they enter your "blind
spot", at the latest.
© Vehicles you are passing
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the
vehicle and your vehicle is less than
9 mph (lS
km/h)), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot .
The
display will not tu rn on if you quick ly pass a
vehicle that side assist has detected (the differ­
ence in speed is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are desig ned to detect the left
and right adjacent lanes when the road lanes are
the normal width . In some situations, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti ­
cal for a lane change. For example:
- If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case , the
system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
- If you are driving through a curve . Side assist
may react to a vehicle that is one lane over
from the adjacent lane .
- If side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cover the radar sensors
c!:> fig. 82 with
stickers, deposits, bicycle whee ls or other ob-
Assistance systems
jects, because they will impair the function. Do
not use side assist when towing a trai ler. For in­
formation on cleaning, see
c!:> page 185.
A WARNING
=
- Always pay attention to traffic and to the
area around your vehicle. S ide assist cannot
replace a driver's attention. The driver alone
is always respons ible for lane changes and
similar dr iv ing maneuve rs .
- In some situations, the system may not
function or its function may be l imited. For
examp le:
- If vehicles are approaching or being left
behind very quickly. The disp lay may not
turn on in time.
- In poor weather conditions such as heavy
rain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles i n the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the system. Have
an authorized Audi dealer or author ized Audi
Service Facility check their funct ion .
(D Tips
- If the window glass in the dr iver's door or
front passenger's door has been tinted, the display in the exterior mirror may be incor­
rect .

Auto and Dynamic, using the r:l.l'e'i button in the
center console or by using the Infotainment sys­
tem . This allows you to switch between a sporty
and a comfortable driving mode, for examp le.
Description
Applies to: vehicles with Audi drive select
The following systems, among other things, are
influenced by drive select:
Engine and automatic transmission
Depending on the mode, the engine and auto­
matic transmission respond more quickly or in a
more balanced manner to accelerator pedal
movements. In the sporty dynamic mode, the
transmission shifts at higher speed ranges .
Suspension control*
The suspension control uses sensors to record in­
formation regarding steering movements, brak­ ing and accelerat ion operations by the driver, as
well as information about the road surface, dr iv­
ing speed, and load. With dr ive select, you can
adjust the suspension control to sporty (dynam­ ic), comfortable (comfort) or balanced (a uto).
Steering
The steering adapts in terms of steering assis­
tance . Indirect steering that moves easily as in
comfort mode is especially su ited to long dr ives
on a highway. In contrast, dynamic mode pro­
vides sporty, direct steering.
Cornering light*
The cornering light adapts to driving on curves.
The pivot ing action and the lighting also adapt to
the mode.
(D Tips
The S selector lever position automatically en­
gages if the dynamic mode is selected.

lines in the rearview camera image help you to
park or maneuver
¢ page 84.
_& WARNING
-Always look for traff ic 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 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 park­
ing system may be impaired as a result.

Intelligent Technology
- Note that on wet streets, the front wheels
can "hyd roplane" if d riving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev highe r sud­
denly when the vehicle begins hyd roplaning.
Fo r this reason, adap t your speed to the
road co nditio ns to reduce t he risk of an acc i­
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 ve hicle w ith a conventional e nergy sys­
tem is not driven for a long time, the vehicle bat ­
tery is dra ined by equipment (for example, the
immobilizer) . In certain circumstances, there
could may not be enough energy to start the en ­
gine .
Your veh icle is equipped with a n intelligent ene r­
gy management system for d istr ibut ing electric i­
ty . This s ignificantly improves the sta rting ability
a nd increases t he ve hicle battery life .
The energy management system Is made up of
battery diagnosis , idling current management ,
and dynamic energy management .
Battery diagnosis
The batte ry diagnos is determines the ve hicle bat­
tery charge level. The sensors dete rm ine the bat ­
tery voltage, the battery cur rent, and the battery
temperature. The c urrent charge level and the
pe rformance of the veh icle battery are deter ­
m ined based on th is .
Idling current management
The idling cu rrent management dec reases the
e n ergy used wh ile parked . With the eng ine
sw itched off, it manages the energy distribution
to the differe nt elect rical components. Data from
t he batte ry diagnos is is taken into account fo r
this.
94
De pend ing on the vehicle batte ry c harge level,
e lectrica l eq uip ment is switched off one item af ­
te r the other to p revent t he vehicle battery from
dra ining and to ma inta in the starting ab ility.
Dynamic energy management
W hile driv ing , d ynam ic ene rgy man ageme nt di s­
tribu tes the ap propr iate amo unt of energy to t he
electrica l eq uip ment . It contro ls t he battery
c h arge level so that the amount o f energy is not
greater than the amount being generated in or ­
der to maintain an opt imal vehicle battery charge
l evel.
(D Tips
- Energy management cannot overcome the
laws of physics. Not e that the charge level
and length of the veh icl e bat tery life a re
limited .
- Wh en the sta rting ability is endangered, the

What you should know
Maintaining the starting ability is the highest
priority .
A lot of st ress is placed on the veh icle battery
whe n driving short distances, d uring city d riving,
and at cold times of t he year. A lot of ene rgy is
u sed but li tt le is generated .
It is also critical
whe n the engi ne is no t ru nning but electrical
equipmen t is sw it c hed on . In t his ca se, energy is
u sed but none i s generate d.
In si tuati ons like t his, energy management w ill
ac tiv el y regulate the d is tr ibution of energy .
Long periods without use
If you do not drive yo ur vehicle for severa l days o r
wee ks, electrica l equ ipment is g radua lly sca led
bac k or sw itched off . Th is reduces energy use and
ensures the vehicle will be ab le to s tart a fter long
p er iods o f time . Some conven ience f unct ions,
s uch as in terior lig htin g, m ay not be available un ­
d er cert ain circu m sta nces. These c onve nien ce
f unct ions w ill be avail able ag ain once yo u sw itch
t h e ignit io n on and sta rt the eng ine. .,.

Airbag syste m
If the front passenger airbag deploys , the Feder ­
al Standard requires the airbag to meet the "low risk" deployment criteria to help reduce the risk
of injury through interaction with the airbag.
"Low risk" deployment occurs in those crashes
that take place at lower decelerations as defined in the electronic control unit . ~
page 124
Alway s rem ember: Even though you r veh icle is
equipped with Advanced Airbags, the safest place
for children is properly restrained on the back
seat. Please be sure to read the important infor­
mat io n in the sections that follow and be sure to
heed a ll of the WARN INGS .
_& WARNING
To reduce the risk of inj ury when an airbag in­
flates, a lways wear safety belts properly .
-If you are unrestrained, leaning forwa rd, s it­
t ing s ideways or o ut of pos ition in any way,
yo ur risk of injury is much higher .
- Yo u will also receive serious injur ies and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced Airbag r:!> page 114.
_& WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat wi ll be
ser iously injured and can be killed if the front
airbag inflates -even w ith an Advanced Airbag
System .
- Although the Advanced A irbag System in
your vehicle is designed to turn off the front
airbag when a rea rward-facing child re­
straint has been insta lled on the front pas­
senger seat, nobody can absolutely guaran­
tee that deployment is impossible in all con­
ceivable s ituations that may happen during
the useful life o f you r vehicle .
- T he inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the chi ld safety seat and child
against the backrest, center armrest, door,
or roof.
- Always install rearward-facing chi ld re­
straints in the back seat.
120
- If you must install a rearwa rd facing child
safety seat on the front passenger seat be ­
cause of exceptional circumstances and the
PA SS EN GER AIR BAG OFF light does not
come on and stay on, immediately install
the rea r-facing child safety seat in a rear
seating position and have the ai rbag system
inspected by your authori zed Aud i dealer.
_& WARNING
If, in exceptional ci rcums tances , you must in­
stall a forward-facing child restraint on the
front passenger's seat :
- Always make sure the forward-facing sea t
has been des igned and certified by its man ­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forward -facing child restraint
up against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest posit ion in the up and down ad ­
justment range and move it back to the
rearmost posit ion in the seat's fore and aft
adjustment range, as far away from the a ir­
bag as poss ible, before installing the for ­
ward-facing chi ld restrain t.
- Always make sure that the safety be lt upper
anchorage is behind the ch ild restraint and
not next to o r in front of the child rest raint
so that the safety be lt will be p roperly posi­
tioned.
- Always move the passenge r seat into its
rearmost posit ion i n the seat's fo re and aft
ad justmen t range, as far away from the a ir ­
bag as poss ible, before install ing the for ­
ward-facing chi ld restraint. The backrest
must be adjusted to an upright position.
- Ma ke sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the time
whenever the ign it ion is switched on.
' Advanced Airbag System components
The front passenger seat in your veh icle has a lot
of very impo rtant parts of the Advanced A irbag
System in it . These parts include the weight-
sensing mat, sensors , wir ing, brackets, and .,.

more. The function of the system in the front
passenger seat is checked by the electronic con­
trol unit when the ignition is on . The control unit
monitors the Advanced Airbag System and turns
the airbag indicator light on when a malfunct ion
i n the system components is detected . The func ­
tion of the airbag indicator light is descr ibed in
greater detail below . Because the front passen­
ge r seat contains important parts of the Ad­
vanced A irbag System, you m ust take care to p re­
vent it from being damage d. Damage to the seat
may prevent the Advanced Airbag for the front
passenger seat from doing its job in a crash.
The front Advanced Airbag System consists
of the following :
-Crash sensors in the front of the vehicle t hat
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An electronic control un it, with integrated
crash sensors for front and side impacts. The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit a lso "de ­
c ides " whether the safety be lt pretens ione rs
sho uld be activated .
- An Advanced Airbag with gas generator and
contro l valve for the d river ins ide the s teer ing

A WARNING ,-
Damage to the front passenge r seat can pre-
vent the front airbag from working properly.
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from f unct ion ing
properly .
- Repairs to the front passenger seat must be
performed by qualified and p roper ly trained
wo rkshop personne l.
- Never remove the front passenger or d river
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble or remove parts from the
seat or disconnect w ires from it.
- Never carry sharp objects in your pockets or
p lace them on the seat . If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work p roper ly .
- Never carry things on your lap or carry ob­
jects on the passenge r seat . S uch items can
increase the weight reg istered by the
weight-sensing mat and s end the wrong in­
formation to the a irbag control unit.
- Never store i tems unde r the front passenger
seat. Parts of the Advanced Airbag System
un der t he passenger se at could be

Airbag syste m
damaged, preventing them and the airbag
system from working properly.
- Never place seat covers or rep lacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats .
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side a irbag in the seat
backrest from deploying properly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger seat.
The add it ional padding will prevent the
weight-sens ing mat in the seat from acc u­
rately reg istering the ch ild restraint or per­
son on the seat and prevent the Advanced
Airbag System from funct ioning properly.
- If you must use a child rest raint on the front
passenge r seat and the child restraint man­
ufacturer 's instructions require the use of a
towel, foam cushion or something else to properly position the ch ild restraint, make
certain that the
PA SSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
- If the
PASSEN GER AIR B AG OFF light does
not come on and stay on, immed iately in­
stall child restraint in a rear seating position
and have the airbag system inspected by
yo ur autho rized Aud i deale r.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
