circulation .
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
I@ REARI button for more than two seconds. This

remains stored up to approximately 15 minutes
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.

there is no vehicle located in the area that is criti ­

- 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

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.

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 ­

road surface, driving speed, and load. With dr ive

sporty (dynamic), comfortable (comfort) or ba l­

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

bution of power varies depend ing on the selected

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 .

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,
c:::;,(D in General information
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.
