Central locking
Description
You can lock and unlock the veh icle centrally . You
have the following options:
- Remote control key
c> page 25,
-Sensors in the door handles* c> page 26,
-Inner central locking switch c> page 2 7, or
- Lock cylinder on the driver's door
c> page 28.
Turn signals
The turn s ignals flash tw ice when you un lock the
veh icle and flash once when you lock the vehicle.
If the vehicle is unlocked and the flashing contin­
ues, then
- one of the doors or the luggage compa rtment
lid is open,
- the ignition is still switched on, or
- the P selector lever position (vehicles with au -
tomat ic transmission*) is not engaged.
Auto Lock
The Auto Lock function locks all doors and the
luggage compartment lid once the speed has ex­
ceeded approximately 9 mph (15 km/h) .
T he vehicle can be unlocked if the opening func­
tion in the central locking system switch is used,
one of the door handles is pulled or the ignition key is removed.
In the event of a crash with airbag deployment,
the doors will also automatically 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 if
only the driver's door or the entire vehi ­
cle shou ld unlock when unlocking

Opening and closing
- If the driver's door is open, the vehicle cannot
be locked by pressing the
fi'.J button on the re­
mote contro l key or touching the locking sen­
sor* on a door.
- When locking using the
ffi button in the central
locking switch, the vehicle will not lock if a door
is open
c> page 27.
- If the most recently used convenience key* is in
the luggage compartment, the luggage com­
partment lid automatically unlocks again after
closing it
c> page 28. The emergency flashers
blink four times.
Do not lock your vehicle with the remote control
key or convenience key* until all doors and the
luggage compartment lid are closed . This helps
to prevent you from locking yourself out acc iden­
tally .
A WARNING
- When you leave the vehicle, always remove
the ignition key and take it with you. This
will prevent passengers (children, for exam­
ple) from accidenta lly being locked in the
vehicle should they accidentally press the
power locking switch in the front 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.

F ig. 81 Sensor detection range
Fig. 82 Display on the exterior mirror
Side assist helps you monitor your blind spot and
traffic behind your vehicle. Within the limits of
the system, it warns you about vehicles that are
coming closer or that are traveling with you with­
i n sensor range
(D ¢ fig. 81: if a lane change is
classified as critical, the display@in the exter io r
mirror
¢fig. 82 turns on.
The display in the left exter ior mirror provides as­
sistance when mak ing a lane change to the left,
while the disp lay in the right exterior mirror pro­
vides assistance when making a lane cha nge to
the right .
Information stage
As long as you do not activate the turn signal,
side assist
informs you abou t veh icles tha t are
detected and classified as critical. The disp lay in
the mi rror turns on, but is dim .
The display remains dim in the in formation stage
so that your view toward the front is not distur ­
bed.
80 Warning stage
If you
activate the turn signal, side assist warns
you about vehicles that are detected and classi­
fied as critica l. The display in the respective mir­
ror blinks brightly.
If this happens, check traffic
by g lancing in the exterior mirrors and over your
shou lder ¢.&

Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical 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 mirror will
turn on.
@ Vehicles traveling with you
Vehicles 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 turn on if you quickly 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 designed 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. 84 with
stickers, deposits, bicycle wheels or other ob-
Assist
jects, because they will impair the function. Do
not use side assist when towing a trailer. For in­
formation on cleaning, see
c!:>page 191.
A WARNING
-- Always pay attention to traffic and to the
area around your vehicle. Side assist cannot replace a driver's attention. The driver alone
is always responsible for lane changes and
similar driving maneuvers .
- Improper reliance on the side assist system can cause collisions and serious personal in­
jury:
- Never rely only on side assist when chang­
ing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your
blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not
function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display 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
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(I) 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 authorized Audi
Service Facility check their function.
