Warning stage
If you activate the turn signa l, side assist warns
you abou t veh icles that are detected and classi­
fied as critical. The display in the respective mir ­
ror blinks brightly. If this happens, check traffic
by glancing in the exterior mirrors and over your

p le)
Side assist funct ions at speeds above approxi­
mately 19 mph (30 km/h) .
(D Approaching vehicles
In certain cases, a vehicle w ill be class ified as
c ritical for a lane change even if it is still some­
what far away. The faster a vehicle approaches,
the sooner the display in the exterior m irror will
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indica ted in the
exterior mirror if t hey are classified as critical for
a lan e change. A ll 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 (15 km/h)), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot.
The display wi ll not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ ­
ence in speed is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the norma l 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 you are driving on
the edge of your lane . If this is the case, the
.,,_

Cl 00 ... N r-­N ... 0 r-­Vl 00
system may have detected a vehicle in another
l ane that is
not adjacent to your current lane .
- If you are dr iving t hrough 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 weat her condit ions . The side assist
functions a re limited.

A WARNING
-Always pay atte ntion to traffic and to the
area aro und yo ur vehicle. Side assist cannot
rep lace a dr ive r's attention. The dr ive r alone
is a lways responsib le for lane changes and
s imi lar driving maneuvers .
- In some situat ions, the system may not
function or its funct io n may be limited . For
example:
- If vehicles a re a ppro ac hi ng o r being le ft
behind very quickly. The display may not
tur n on in t ime .
- I n poo r weather cond itions s uch as heavy
rain, snow o r heavy mist .
- On very wide lanes, in t ight curves, o r if
there is a rise in the road s urface. Vehicles
in the adjacent lane may not be detected
beca use they are outs ide of the sensor
range.
{Ll) Note
The sensors can be disp laced by im pacts o r
damage to the bumpe r, whee l housing and
underbody. Th is can impa ir the system. Have

vehicle's features.
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.
Suspension control (Audi magnetic ride)*
The suspension control uses sensors to record in­
format ion regarding steering movements, brak­
i ng and acceleration operations by the driver, as
well as information about the road surface, driv­
i ng speed, and load. W ith dr ive se lect, you can
adjust the suspension control to sporty (dynam­
ic ), comfortable (comfort) or balanced (auto).
Steering
The power steering adapts . Indirect steering that
moves eas ily as in comfort mode is espec ially
su ited to long drives on a highway . The dynamic
mode provides sporty, direct steering.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty .
(D Tips
In some models, the maximum vehicle speed
can only be reached in the auto and dynamic
modes .

Rear parking system
Description
A pplies to: ve hicles with rear park ing system
The rear parking system is an audible parking
aid .
Desc ripti on
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 informat ion on
cleaning, see
c::;.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.

- Always make sure that the safety belt upper
anchorage is beh ind the child restraint and
not next to or in front of the chi ld restraint
so that the safety belt will be properly pos i­

the seat to signa l to the Airbag System that
the seat is occupied by a person w hen it is
not, or to sign al that it is occ upied by some­
one who is heavier than t he pe rson actua lly
sitting on the seat . The presence of addi­
tiona l objects could ca use the passenge r
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 wi tho ut the object on t he seat .
- Make sure that the

Advanced Airbag System components
The front passenger seat in you r vehicle has a lot
of very impo rtant parts of the Advanced Airbag
Sys tem in it. These pa rts in cl ude the capaci tive
passenger detection system, w iring, brac kets,
and more. The control unit monitors the system
on the front passenger seat when the ignition is
switched on and turns the airbag indicator light
on when a malfunct ion in the one of the system
components is detected
¢ page 206. Because
the front passenger seat contains important
pa rts of the Advanced Airbag System, you must
take ca re to prevent it from be ing damaged .
D amage to the seat may p reve nt the Advanced
A irbag System fo r the fron t passenger seat from
doi ng its job in a crash.
The front Advanced Airbag System consists
of the following :
-Cr ash sensors in the front of the vehicle t hat
measure vehicle accelerat ion/dece lerat ion to
Airbag syste m
prov ide information to the Advanced A irbag
System about the severity of the cras h.
- An electronic contro l uni t, with integrated
cras h sensors for front and side impacts . The
control unit "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 it h gas generator for the
driver inside the steering 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 ­
neat h the front passenger seat cover. This sys­
tem meas ures the e lectr ica l capacitance of the
person in the seat. The informat ion registered
is sent cont inuously to the elect ronic contro l
un it to reg ulate dep loymen t of the front Ad­
vance d Airbag on the p assenger side.
- An airbag monitor ing system and ind icator
ligh t
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
s teer ing whee l o r i nst rument p anel. The infor­
mation registered is sent con tinuous ly to the
elect ronic 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¢ page 206,
fig. 164 and tells you when the front Advanced
Airbag on the passenger side has been turned
off.
- A sensor in the safety be lt 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 the e lectronic
control un it .
A WARNING
-
Damage to the front passenge r seat can pre­
vent the front airbag from wo rk ing prope rly.
- Imp roper repair or d isassembly of the front
passenger and driver seat will p reve nt the
