Opening and closing
Central locking
Description
You can lock and unlock the veh icle centrally . You
have the following options:
-Remote control key¢ page 40,
-Sensors in the door handles* ¢ page 40,
-Lock cylinder on the driver's door c::> page 42,
or
-Interior central locking switch c::> page 41.
Turn signals
The turn s ignals flash twice when you unlock the
veh icle and flash once when you lock the veh icle.
If they do not flash, then one of the doors, the
rear lid or the hood is not closed.
Automatic locking (Auto Lock)
The Auto Lock funct ion locks all doors and the
luggage compartment lid once the speed has
ex­
ceeded approximately 9 mph (15 km/h).
The vehicle can be unlocked if the opening func­
tion in the central locking system sw itch is used
or one of the door handles is pulled.
In the event of a crash with airbag deployment,
the doors will a lso automat ically unlock to allow
access to the vehicle.
Selective door unlocking
The doors and luggage compartment lid will lock
when they close . You can set in the Infotainment
system whether
only the driver's door or the en­
tire vehicle should be unlocked when unlocking
c::> page 41.
Unintentionally locking yourself out
Only lock your vehicle when all of the doors and
the luggage compartment lid are closed and the remote control key is not in the vehicle . This
helps to prevent you from locking yourse lf out
accidentally .
The follow ing cond it ions prevent you from lock­
ing your remote control key in the vehicle:
Opening and closing
-If the driver's door is open, the vehicle cannot
be locked by pressing the
fi'.) button on the re­
mote contro l key or by touching the locking
sensor* on a door.
-If the most recently used convenience key* is
detected in the luggage compartment, the lug­
gage compartment lid automatically unlocks
again after closing it.
-If the convenience key* that was last used is de­
tected inside the vehicle, then the vehicle will
not be able to lock from the outside .
_& WARNING
---
-When you lock your vehicle from outs ide,
nobody- espec ially children
-should rema in
inside the vehicle. Remember, when you
loc k the vehicle from the outside the win­
dows cannot be opened from the inside .
- When you leave the vehicle, always take the
ignit ion key with yo u. This will prevent pas­
sengers (children, for examp le) from acci­
dentally being locked in the vehicle should
they accidentally press the power locking
switch in the doors.
- Do not leave children inside the vehicle
un­
supervised. In an emergency it would be im­
possible to open the doors from the outside
without the key.
(D Tips
-Do not leave valuables unattended in the ve­
hicle. A locked vehicle is not a safe!
-The LED in the driver's door rail blinks when
you lock the vehicle. If the LED lights up for
approximately 30 seconds after locking,
there is a malfunction in the central locking
system. Have the problem corrected by an
authorized Audi dealer or authorized Audi
Service Facility.

... Bring the steering wheel into the desired posi­
tion .
.,. Push the lever against the steering column un­
til it is secure .
_&. WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the
vehicle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steering wheel so
that there is at least a 10 in (2S cm) dis­
tance between your chest and the steering
wheel. If you do not maintain this distance,
the airbag system will not be able to provide
its full protection.
-If your physical characteristics prevent you
from sitting at least 10 in (2S cm) or more
away from the steering
wheel, see if an au­
thorized Audi dealer or authorized Audi
Service Facility can provide adapters that
will help .
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision . Always make sure
that the steering wheel is level with your
chest.
- Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of injury if the airbag
deploys.
- Never hold the steering wheel in the 12
o'clock position or with both hands on the
rim or the center of the steering wheel.
Holding the steering wheel incorrectly sig­
nificantly increases the risk of injury to the
hands, arms and head if the driver airbag
deploys .

Audi pre sense
Introduction
A pp lies to: ve hicles w ith Audi p re se nse
W ithin the limits of the system, the pre sense
functions can initiate measures in particularly
dangerous situations to protect the veh icle pas­
sengers and other road users .
- Due to the interlinking of various vehicle sys­
tems, crit ical dr iving s ituations can be detected
by
pre sense basic and measures for preventa ­
tive occupant protection are can be initiated .
- The
pre sense front system uses the data from
the adapt ive cruise control* radar sensors and
the camera to calculate the probab ility of a col­
li sion. Withi n the limits of the system, an im­
pending collision with vehicles can be dete cted
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec­
essary. If needed, it can initiate a partial or full
deceleration to reduce the co llision speed or to
avo id the collision under certain c ircumstances .
In conjunct ion with pre sense basic/rear, the
front safety belts are also revers ibly tensioned
when needed . The pre sense front is also active
whe n adapt ive cruise control* is swit ched off.
- Pre sense rear contains pre sense basic func­
tions. It uses the data from the side assist* ra­
dar sensors and calculates within the limits of
the system the probab ility of a rear end coll i­
s ion with the vehicle behind you. Pre sense rear
is also active when side assist* is switched off.
- Within the limits of the system,
pre sense city
uses the camera data and can detect an im ­
pending collision with vehicles and pedestrians.
In this case, the system warns the driver visual ­
ly, acoustically and with a jerk on the brakes if
necessary. If needed, it can initiate a full decel­
eration to reduce the collision speed or to avoid
120
the collision under certa in circumstances . In
conjunction with pre sense basic/rear, the front
safety belts are also reversibly tensioned when
needed .
A WARNING
-
Read the general information inc> & in Gen-
eral information on page 109,
c> & in Gener­
al information on page 130.
(D Tips
- Certain pre sense funct ions sw itch off when
dr iving in reverse.
- The pre sense functions may not be availa­
ble if there is a malfunct ion in the ESC sys­
tem or the a irbag control module.
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's airbag is deactivated .
- Switch the pre sense off when you are not
using public streets or when loading the ve­
hicle onto a vehicle carrier, tra in, sh ip or
other type of transportation. This can pre­
vent an undesired intervention from
the pre
sense system.
Audi pre sense basic
Description
App lies to : vehicles wi th Audi pre sense basic
The pre sense bas ic functions are activated at a
speed of approx imately 20 mph (30 km/h) or
higher .
The following functions can be triggered under certain condit ions w ith in the lim its of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy brak ing): the front safety belts
have reversib le be lt tens ioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger again.
- Closing the windows and sunroof* .

Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re­
corder (EDR) . The main purpose of an EDR is to
record, in certain crash or near crash-like situa­
tions, such as an airbag deployment or hitting a
road obstacle, data that will assist in understand­
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy­
namics and safety systems for a short period of
time, typically 30 seconds or less . The EDR in this
veh icle is designed to record such data as :
- How various systems in your vehicle were oper­
at ing;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can he lp prov ide a better understand­
ing of the circumstances in which crashes and in­
juries occur. NOTE: EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g.,
name, gender, age, and crash location) are re­
corded. Howeve r, other parties, such as law en­
forcement, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
To read data recorded by an EDR, specia l equip­
ment is required, and access to the vehicle or the
EDR is needed. In addition to the vehicle manu­
facturer, other parties, such as law enforcement,
that have the specia l equipment, can read the in­
formation if they have access to the vehicle or the
EDR.
Some state laws restrict the retrieval or down­
l oading of data stored by ED Rs insta lled in a vehi ­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own­ er's consent.
Intelligent Technology
Audi will not access the EDR and/or simi la r data
or give it to others -
- unless the vehicl e owner (or lessee if the vehi­
cle has been leased) agrees; or
- upon the official request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the jud ic ial
discovery process.
- Aud i may also use the data for research about
veh icle operation and safety performance or
prov ide the data to a th ird party for research
purposes without ide ntify ing the specific vehi­
cle or information about the identity of its own­
er or lessee and only after the reco rded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equipped w ith a number of
electronic control modules for various vehicle
systems, such as engine management, emiss ion
contro l, airbags, and safety be lts.
T hese elect ronic contro l modu les record data
dur ing normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capab ility of these
modules is limited to data (no sound is record­
ed). Only a small amount of data is actually re­
corded over a very limited period of time, or stor­
ed when a system fault is detected by a control
module . Some of the data stored may relate to
vehicle speed, direction, or braking, as well as re­
straint system use and performance in the event
of a crash. Stored data can also only be read and
down loaded w it h special equipment that is di­
rectly connected to the vehicle .
(D Tips
Your vehicle may be equipped w ith Aud i con­
nect. Your use of certain Audi connect fea­
tures requires wire less services that are pro­
vided by a third party wireless telecommuni ­
cations provider . For details regarding how in­
formation obtained through Audi connect is
collected, processed, transmitted, used, and
shared, please see your contract with the
wireless telecommunications provider and the
IJJJ,-
