The air quality sensor that is de­
signed for diese l and gasoline exhaust auto ­
matically sw itches the recirculation mode on or
off depend ing on the level of pollutants in the
outside air.
In recirculation mode, the air inside the vehicle is
circu lated and filtered. This prevents the unfil­
tered a ir outside the vehicle from entering the
veh icle inter ior . We recommend switching recir ­
culation mode on when dr iv ing through a tunnel
or when s itting in traffic

IQiil REAR ! Switching the rear window defogger
on and off
If the rear w indow defogger is activated when
the ignition is switched on, the battery manage­
ment determines based on the battery charge if
it is possible to turn on. Ot he rwise, the rear win ­
dow defogger functions with the engine running
and switches off automatically after approxi­
mately 10 - 20 minutes, depending on the out­
side temperature.
To prevent the rear w indow defogger from
sw itching off automatically, press and hold the

after turning off the ignition.
A WARNING
You should not use the recirculation mode for
an extended period since no fresh air is drawn
in. With the air-conditioning switched off, t he
windows can fog up, which increases the risk
of an acc ident.

are indicated by the time they enter your "blind
spot", at the latest .
@Vehicles you are passing
If you slowly pass a veh icle that side assist has
detected (the d ifference in speed be twee n the
veh icle and your veh icle is less t han 9 mph (15
km/h)), the d isplay in the exterior mirror turns
on as soon as the vehicle enters your blind spot .
The display will not tu rn o n if you quick ly pass a
veh icle tha t side assist has detected (the differ ­
ence in speed is greate r than 9 mph ( 15 km/h)).
Functional limitations
The rada r senso rs a re designed to detect the left
and right adjacen t lanes when the road lanes a re
the normal wid th . In some s ituat ions, the d isplay
in the exter ior mirror may tur n on even tho ugh
there is no vehicle located in the area that is criti ­
cal for a lane change. For example:
- If the lanes a re nar row o r if yo ur are dr iving on
the edge of your lane. If this is the case, the system may have detected the vehicle in anoth­
er lane t hat is
not adjacent to your current lane.
- If you are dr iv ing t hrough a curve. Side assis t
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 condit ions . The side assis t
functions are limited.
Do not cove r the radar sensors¢

s tick ers, deposits, bicycle whee ls o r othe r ob­
jects, beca use they w ill impa ir the f unction . For
information on cleaning, see¢
page 266.
A WARNING
-Always pay attention to traffic and to the
area aro und your vehicle. Side assist cannot
rep lace a dr iver's attention. The drive r alone
is a lways responsible for lane changes and
similar driving maneuvers.
- In some situat io ns, the system may not
function or its funct ion may be limited . For
example:
78
-
- If vehicles are app roaching or being left
behind very q uickly. The disp lay may not
turn on in time.
- In poor weathe r cond it ions such as heavy
r ain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
the re is a r ise in the road surface. Veh icles
i n the adjacent lane may not be detected
because they are outside of the sensor
r ange.
- Aud i side assist can not detect all ve hicles
under all conditions, which can inc rease the
r is k of acciden ts.
- Please note that s ide ass ist only d isp lays ap­
proach ing vehicles or veh icles in your blind
spot if your veh icle is traveling a t least
19 mph (30 km/h).
- In ce rtain s ituations, t he sys tem may not
wo rk or its funct ion may be limited. For ex­
ample:
- The disp lay may not turn on at the r ight
time if vehicles are approaching or pass ing
very quickly.
- In poor weathe r con ditions, such as heavy
r ain, snow or fog.
- In very wide lanes, in tight c urves o r whe n
the re are slopes in the roadway, vehicles
i n the ne ighboring lanes may not be de­
tected because they a re outside of the
senso r range.
(D Note
The sensors can be d isplaced 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 Fac ility check the ir f unct io n.

Parking systems
Parking systems
General information
A ppl ies to: ve hicles w ith rear pa rk in g sys te m /p ark in g system
p lus
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.
82
(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 .

Intelligent Technology
Operating nois e
Noises may occur when br aking depend ing on the
speed, b raking force and outside cond itions such
as tempe rature and humidity.
Effect of water and road salt
I n ce rtain s ituations, for example after driving
through wa ter, in heavy ra in, afte r ove rnig ht con ­
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dried" first w ith a few careful brake applica­
tions.
At highe r speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time . Th is action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking eff ect can also be reduced if you are
driving on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied .
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads .
If you usually avoid heavy braking or if there is
corros ion present, occasional heavy braking at
h igh speeds is recommended to clean the brake
rotors and pads
¢ ,& .
Brake system malfunct ion
if you notice that the brake pedal travel has sud­
denly increased, then a brake c ircuit in the dual­
circu it brake system may have malfunct ioned.
Drive to an authorized Aud i dea ler or aut horized
Aud i Serv ice Facility immediately to have t he
p roblem co rrected . On the way there, drive with
reduced speed and keep in mi nd that you w ill
need a longer d istance to s top and you w ill need
to p ress the brake pedal har der.

Low brake fluid level
When the brake fluid level is low, m alfunc tions in
the b rake system may occur . The brake fluid leve l
i s e lectronically monitored .
Brake booster
The brake booster ampl ifies the press ure you ap­
ply to the brake pedal.
_&. WARNING
- New brake pads do no t achieve the ir full
braking effect during the first 2 50 m i
-
(400 km). They m ust be "b roken in" first .
However, you can compensate fo r the
slightly reduced braking force by pressing
firm ly on the brake pedal. Avoid heavy brak­
ing during the break-in period .
- On ly app ly the bra kes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­ danger other road users . This increases the
ris k of an accident.
- On steep slopes, reduce the speed and se­
lect a lower gear o r lower selector leve r po·
si tion. D rive as little as possible while press­
ing the bra ke pedal and avoi d pu tting your
left foot on the brake pedal while dr iv ing.
This could cause the bra kes to overhea t and
impair the efficiency of the b rakes.
- Do not let the bra kes "grind" by always
keep ing your foot on the bra ke pe dal. This
can cause the brakes to overheat, inc rease
wear and increase braking distance unneces­
sarily .
- Ce rtain weather and operating conditions
such as d riving through water, dr iv ing in
heavy rain or driv ing after wash ing your ve­
hicle can impai r the effective ness of the
brakes . In t he win ter, ice may build up o n
the bra ke pa ds, rotors and dr ums. Check
t hese components by b raking carefully. Ap ­
plyi ng the brakes carefully seve ral times
dries the brakes and removes ice build-up .
- The efficiency o f th e brakes can also be im­
p air ed by dr iv ing for long s tretches on roads
covered with sa lt wi thout using the bra kes .
You can remove salt deposits from the ..,.

brake rotors and pads by caref ull y applying
the brakes several t imes .
-If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are vent ilated properly. Otherwise,
the brake system could overheat, wh ich re­
duces the ir effectiveness .
- Failure of a brake circuit impairs b raking
performance , which increases brak ing dis­
tance. Avoid driving the vehicle and have it
towed it to the nearest author ized Audi
dealer or author ized A udi Se rvice Facility.
- Never let the vehicle roll while t he engine is
stopped because this increases the risk of a n
acc iden t.
- If the bra ke booste r is not working, you will
have to press m uch ha rder on the bra ke
ped al to compensate for the lac k of th e
booster.
- Never let the brakes "rub " by pressing the
pedal light ly when bra king is no t actually
ne cessary . T his cause s the brakes to over­
hea t and i ncre ases br aking di stance and
ca uses wear.
- B efo re driv ing downh ill a long dis tance on a
steep h ill, decrease your speed and se lec t a
l ower gear . This makes use of the engine
braking effect and relieves the brakes . If
you need to b rake additionally, brake in in­
tervals and not continuously.
@ Tips
- If the brake booste r is not working, you
must press the brake pedal with much more
fo rce than normal.
- If you retrofit yo ur vehicle with a front spoil­
er, whee l
covers or similar items, make sure
that the air flow to the front whee ls is not
i nterr upted . Otherw ise the brake system
ca n become too hot .

Safe driving
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle, the driver as well as the driver's abili­
ty to concentrate on the road without being dis­
tracted.
The driver is respons ible for the safety of the ve­
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
vehicle increase and you also become a hazard to
everyone else on the road
c:::> .&_. Therefore :
~ Do not let yourself be distracted by passenger
or by using a cellular telephone.
~ NEVER drive when your driving ability is im­
paired (by medications, alcohol, drugs, etc.).
~ Observe all traffic laws, rules of the road and
speed limits and plain common sense.
~ ALWAYS adjust your speed to road, traffic and
weather conditions.
~ Take frequent breaks on long trips. Do not drive
for more than two hours at a stretch.
~ Do NOT drive when you are tired, under pres­
sure or when you are stressed.
..&, WARNING
Impaired driving safety increases the risk of
serious personal injury and death whenever a
vehicle is being used.
Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving.
Fig. 152 Correct seating position
182
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the driver's seat to the following
position:
~ Adjust the driver 's seat so that you can easily
push the pedals all the way to the floor while
keeping your knee(s) slightly bent
c:::> .&_.
~ Adjust the angle of the seatback so that it is in
an upright position so that your back comes in
full contact with it when you drive.
~ Adjust the steering wheel so that there is a d is­
tance of at least 10 in (25 cm) between the
steering wheel and your breast bone
c:::>fig. 152.
If not possible, see your authorized Audi deal­
ership about adaptive equipment.
~ Adjust the steering wheel so that the steering
wheel and airbag cover points at your chest and not at your face.
~ Grasp the top of the steering wheel with your
elbow(s) slightly bent.
~ Fasten and wear safety belts correctly
c:::> page 192.
~ Always keep both feet in the footwell so that
you are in control of the vehicle at all times .
For detailed information on how to adjust the
driver's seat, see
c:::> page 47, Seats and storage.
..&, WARNING
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in­
jured by an airbag as it unfolds. To help re­
duce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 in (25 cm) between your breastbone and
the steering wheel.
-Always adjust the driver's seat and the
steering wheel so that there are at least 4 in
(10 cm) between the knees and the lower
part of the instrument panel.
- Always hold the steering wheel on the out­
side of the steering wheel rim with your
hands at the 9 o'clock and 3 o'clock posi­
tions to help reduce the risk of personal in­
jury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
-

Safe driving
_& WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
- Always distribute the load as evenly as
possible .
- Place heavy objects as far forward in the luggage compartment as possible.
- Never exceed the Gross Axle Weight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceeding permissible weight
standards can cause the vehicle to slide and hand le differently .
- Please observe information on safe driving
c';> page 181.
_& WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­ cause the rear lid cannot be fully closed .
- If you absolutely must drive with the rear lid open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the convertible top,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed .
_& WARNING
'
-
Always make sure that the doors, all win­
dows, the convertible top and the rear lid are
securely closed and locked to reduce the risk
of injury when the vehicle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked.
186 -
Never leave your vehicle unattended espe­
cially with the rear lid left open. A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment . Vehicle occupants must al­
ways be properly restrained in one of the ve­ hicle 's seating positions.
{1) Tips
- Air circulation helps to reduce window fog­
ging . Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar. The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­ ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter

The PASSENGER AIR BAG OFF~; light in the
headliner tells you when the front Advanced Air­
bag on the passenger side has been turned off by
the electronic control unit.
Each t ime you turn on the ignition, the
PASSEN·
GER AIR BAG OFF,-;; ON ~
light will come on
for a few seconds and:
- PASSENGER AIR BAG OFF~; will come on if
the front passenger seat is not occupied,
- PASSENGER AIR BAG OFF ~; will come on if
the e lectrical capacitance measured by the ca ­
pacitive passenger detection system for the
front passenger seat equals the combined ca­ pacitance of an infant up to about one year of
age and one of the rearward-facing or forward ­
facing child restraints listed in Federal Motor
Vehicle Safety Standard 208 with which the Ad­
vanced Airbag System in your vehicle was certi­
fied. For a listing of the child restraints that
were used to certify your vehicle's compliance
with the U.S. Safety Standard¢
page 220.
-PASSENGER AIR BAG OFF ~; will come on if
there is a small child or chi ld restraint on the
front passenger seat,
- PASSENGER AIR BAG ON @will go off if the
front passenger seat is occupied by an adult as
registered by the capacitive passenger detec­
tion system ¢
page 20 7, Monitoring the Ad­
vanced Airbag System.
The PASSENGER AIR BAG OFF~; light comes on
when electrical capacitance registered on the
front passenger seat is equa l to or less than the
comb ined capacitance of a typ ica l 1 year-old in­
fant and one of the rearward-fac ing or forward­
facing ch ild restraints listed in Federal Motor Ve­
h icle Safety Standard 208 with wh ich the Ad­
vanced Ai rbag System in your vehicle was cert i­
fied.
If the total electrical capac itance registered on
the front passenger seat is more than that of a
198
typical 1 year -old chi ld but less than the weight
of a sma ll adult, the front airbag on the passen­
ger side can deploy (the
PASSENGER AIR BAG
OFF ~;
light does not come on).
If the
PASSENGER AIR BAG OFF~; light does
not come on, the front airbag on the passenger
s ide has not been turned off by the e lectron ic
contro l unit and can deploy if the control unit
senses an impact that meets the conditions stor­
ed in its memory .
For example, the airbag may deploy if :
-a small child that is heav ier than a typical 1
year -old child is on the front passenger seat
(regard less of whether the child is in one of the
child safety seats listed¢
page 220), or
- a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF,-;; light comes on in
the headliner and stays on .
If the front passenger airbag deploys, the Feder­
al Standard requ ires the airbag to meet the " low
risk" deployment criteria to reduce the risk of in­
jur y 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 208, PASSEN­
GER AIR BAG OFF~; ON~ light.
Always remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of posit ion by the rapidly inflating
passenger's airbag in a frontal collision. The a ir­
bag could greatly reduce the effectiveness of the
ch ild restraint and even ser iously injure the child
during inflation.
.&, WARNING
-
A child in a rearward-facing child seat instal­
l ed on the front passenger seat will be seri­
ously injured and can be killed if the front air­
bag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the ch ild seat or
infant carrier with great force and will .,.
