A WARNING ,~
- Always take the vehicle key with you when
leaving the vehicle, eve n for a short period
of time. Th is applies partic ula rly whe n chil­
dren remain in the vehicle. Otherw ise chi l­
dren co uld start the engine, re lease the
p arki ng brake or oper ate elec trical eq uip­
ment such as power windows, which in­
creases the r is k of an accident .
- No one sho uld remain in the vehicle when i t
is locked, especia lly children . Locked doors
make it more difficult for emergency wo rk­
ers to get into the vehicle, which puts lives
at risk.
Starting from a stop
The start assist function ensures that the park ­
ing broke is released automatically upon start ­
ing .
Stopping and setting the parking brake

The parking brake re leases automatically and the
vehicle beg ins to move as soon as you press the
accelerator peda l as usual.
Starting on slopes
When starting on in clin es, the hill start assist
p revents the vehicle from uni ntentiona lly ro lling

not released until sufficient driving force has
been built up at the whee ls .
Dri ving
{!) Tips
Fo r safety reasons, the pa rking bra ke is re­
l eased automatically only when the d river 's
safety be lt is engaged in the b uckle.
Starting to drive with a trailer
To prevent rolling bock unintentionally on on in ­
cline, do the following:
,.. Keep the sw itch pulled ~ and p ress the acce l­
erator peda l. The parking brake stays applied
and prevents the vehicle from roll ing backward .
,.. You can re lease the switch
[21 once you are s ure
that you are transferring enough drivi ng force
to the wheels by pressing the accele rato r pedal.
Depend ing on the we ight of the rig (vehicle and
trailer) and the severity of the incline, you may
ro ll backwards as you start.
Emergency braking function
This is used if the conventional broke system
fails or locks up.
,.. To brake your ve hicle in an eme rgency, pull the
[21 switc h and hold it p ulled.
,.. As soon as you release the
[21 switch or acce ler-
ate, the b rak ing stops.
If you pu ll the switch «el) and hold it above a

App lies to vehicles: with sid e assist

• 0 0 •
Fig. 107 Rear of the ve hicle: pos it io n of t he sensors
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
(D 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 faste r a vehicle approaches,
the sooner t he d isplay in the exter io r mirro r will
turn on.
@Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
98
are indicated by the time they enter your "blind
spot", at the latest.
@ Vehicles left behind
If you slowly pass a veh icle that side assist has
detected (the difference in speed between the ve­
hicle and your vehicle is less than 9 mph or 1S
km/h), the display in the exterior mirror turns on
as soon as the vehicle enters your blind spot.
T he display will not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph or 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 certain s ituations, the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area that
i s cr itical for a lane change. For example:
- if the lanes are narrow or if your 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 that is
not adjacent to your current lane.
- if yo u are driving through a c urve . 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
q fig. 107 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . Do not
use side assist when towing a trailer . For infor ­
mation on cleaning, refer to
q page 205 .
A WARNING
-Always pay attention to traffic and to the
area around your veh icle. S ide ass ist cannot
replace a dr iver's attention . The driver alone
is always responsible for lane changes and
sim ila r driv ing maneuvers.

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, p lease remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trai ler, you must ac­
tivate the trailer operat ion mode

Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a
technically
sound
location. Use only a trailer hitch with a re­
movable ball mount. Always check with the trail­
e r hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact-absorbing
bumper system. No modifications should be
made to the vehicle exhaust and brake systems.
From time to time, check that all hitch mounting
bolts remain securely fastened .
When you are not towing a trailer,
remove the
trailer hitch ball mount. This prevents the hitch
from causing damage should your vehicle be
struck from behind

Trailer brakes
If your trailer is equipped with a brak ing system,
check to be sure that it conforms to all regula­
tions.
T he trailer hydraulic brake system must not be di­
rect ly connected to the vehicle's hydraulic b rake

Safety chains
Always use safety chains between your veh icle
and the tra iler.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check with your Aud i dealer for correct wiring,
switches and relays.
Mirrors
If you are unable to see the traffic behind you us­

stall extended mirrors. It is important that you
always have clear vision to the rear .
A WARNING
