After a cold engine is started, there may be a
brief period of increased noise because oil
pressure must first build up in the hydraulic
valve adjusters. This is normal and not a cause
for concern.
If the engine should not start immediately,
the starting process is automatically stopped
after a short time. Repeat starting procedure.

Steering lock
The steering locks when you turn the engine
off using the
I START ENGINE STOP I button
and open the driver's door. The locked steer­ ing helps prevent vehicle theft.
A WARNING
- Never allow the engine to run in confined
spaces - danger of asphyx iation.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- The brake booster and power steering
only work when the engine is running. If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usual­
ly would, this could lead to crashes and
serious injuries.

82 On the road
-Occasiona l noises when the parking
brake is applied and re leased are norma l
and are not a cause for concern .
- When the vehicle is parked, the parking
brake goes through a se lf-test cycle at
regular intervals. Any assoc iated noises
are norma l.
Parking
Various rules apply to prevent the parked ve­
hicle from rolling away accidentally.
P ar king
,. Stop the vehicle w ith the foot brake.
,. Pull the switch© to apply the parking
brake.
,. Se lect the
P se lector lever position
9 page 112.
,. Turn the eng ine off q _&. .
In addition on incline s and grad es
,. Turn the steering whee l so that your vehicle
wi ll ro ll against the curb in case it should
start to move .
A WARNING
-When you leave your veh icle -even if on­
ly briefly -always take the ignition key
with you. This applies particularly when children remain in the veh icle. Otherw ise
the ch ildren could sta rt t he engine, re­
lease the p arking brake or operate e lec­
trical equipment (e .g. power windows) .
T he re is the risk of an accident.
- When the vehicle is loc ked, no one -par­
t icu la rly not children sho uld remain in
the vehicle . Locked doors make it more
difficult for emergency workers to get in­
to the vehicle -putt ing lives at risk.
Start ing from rest
The starting assist function ensures that the
parking brake is released automatically upon starting.
Stopping and appl ying par kin g brake
,. Pull the switch© to apply the parking
brake.
St arting and automatic ally rel easi ng the
parking b rake
,. When you start to dr ive as usual, the park ­
ing brake is automat ically released and your
veh icle beg ins to move.
When stopping at a traffic signal or stopping in city traffic, the parking brake can be ap­
plied . The vehicle does not have to be held
with the footbrake . The parking brake elimi ­
nates the tendency to creep w ith a dr ive range
engaged. As soo n as you d rive off as usual,
the pa rking brake is re leased automatically
and the vehicle s tarts to move.
Sta rting on slopes
When starting on inclines, the starting assist
prevents the veh icle from u nintent ionally roll­
i ng back. The braking fo rce of the par kin g
brake is not re leased unti l su ff ic ient d riving
f orce has been built up a t the wheels.
(D Tips
Fo r safety reasons, the pa rking bra ke is re­
l eased automatically o nly when t he d riv­
er's safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
,. Keep the sw itch(®) pulled and depress the
accelerator. The pa rking brake stays applied
and p revents the vehicle from roll ing back­
ward .
,. You can release the switch© once you are
sure that you are developing enough for­
ward momentum at the whee ls as you de ­
press the acce lerator.

Depending on the weight of the r ig (vehicle
and trai ler) and the severity of the incline, you
may roll backwards as you start. You can pre­
vent roll ing backwards by holding the parking
brake switch(®) pulled out and accelerating -
just as you would when starting on a hill with
a conventional hand brake.
Emergency braking
In the event that the conventional brake sys­
tem fails or locks.
... In an emergency, pull the switch(®) and
continue to pull it to slow your vehicle down
with the parking brake.
... As soon as you release t he sw itch (®) or ac-
ce lerate, the braking p rocess stops.
If you pull the sw itch(®) and hold it above a
speed of about 5 mph (8 km/h), t he emergen­
cy braking fu nction is in itiated . The vehicle is
b raked at all four wheels by activating the hy­
d ra u lic bra ke system. The b rake performance
i s simi lar to making an emergency stop
c::> &. .
In order not to activate the emergency brak­
ing by m ista ke, an audible warning tone (b uz­
z er) sou nds when the switch®> is pulled. As
soon as the switch(®) is released, or the acce l­
erator pedal is dep ressed, emergency brak ing
stops .
A WARNING
Emergency braking should only be used i n
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed.
Using the parking brake to perform emer­
gency braking will slow you r vehicle down
as if you had made a fu ll brake applicat ion.
T he laws of physics can not be s uspended
even w ith ESP and its associated compo­
nents (ABS, ASR, EDL). In corners and
when road or weather conditions are bad,
a full brake application can cause the vehi­
cle to skid or the rear end to break away -
r isking an accident.

Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed .
The speed warning system warns you if you
are exceeding the maximum speed that you
have set. You will hear a warning tone when
you r speed exceeds the stored value by ap­
proximately 3 mph (3 km/h) . An indicator
li ght . (USA
models) ;a (Canada mode ls) in
the instr ument cluster d isp lay al so tur ns on at
the same time. The indicator light . /.
turns off when the speed decreases be low the
stored maxim um speed .
Se tting a t hreshold is recommended if you
would like to be rem inded w hen you reach a
certain maximum speed. Situations where you
may want to do so incl ude driv ing in a co untry
with a genera l speed limit or if there is a
specified maximum speed for winter tires.
(D Tips
Even though your vehicle is eq uipped w ith
a speed warn ing system, you sho uld still
watch the speedometer to make sure you
are not dr iv ing faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
... Select: !CAR ! function button > Car systems
contro l button > Dri ver ass ist > Speed warn­
ing .
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Sett ings
can each be adjusted in increments of 5 mph
(10 km/h).

-The radar sensor's vision can be reduced
or entirely blocked by rain, snow, and
heavy spray . This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the d irection you
are traveling and the relevant area
around the vehicle.
- Please note that side assist indicates
there are approaching vehicles, o r vehi­
cles in your blind spot, only after your ve ­
hicle has reached a driving speed of at
least 19 mph (30 km/h).
- Side ass ist signal does not work around
tight corners (turning radius less than
328 feet or 100 m).
- Side assist is no replacement for the driv­
er's full attention . The driver alone is re­
sponsible for lane changes and similar
driving maneuvers. A lways keep an eye
on the direction you are traveling and the
relevant area around the vehicle.
(D Note
- To ensure that you do not adversely af­
fect side assist, do not block the area on
the rear bumper where the radar sensors
are located with foreign objec ts (such as
stickers or bicycle racks).
- Make sure that the signal light on the
outside m irror is not blocked by st ickers
or other items .
@ Tips
-Side assist automatically deactivates if it
detects that the radar sensors are
blocked ~
page 104. The indicator light
on the button goes out .
- The area on the bumper where the radar
senso rs are located must consistently re­
main free of snow, ice, and heavy soiling
so that side assist can function properly.
Follow the additional notes on
.:!>page 104 .
-Additional tinting on the front side win­
dows can make it harder to see and cor­
rectly understand the signa l light on the
outside mirror.

Sensor detection area
Applies to vehicles: with side assist
t
Fig. 102 Sc hemat ic illu st ration : Sen sor detect io n area
The detection ¢ fig. 102 of the radar sensor
detection area is made up of:
- the approach area (light green area)@,
about 230 feet (70 m) beh ind the veh icle,
and
- the "b lind spot" (dark green area) @.
The radar sensors cover the adjacent left and right lanes. Other lanes are
not covered by the
radar sensors .
(D Tips
Side assist does not measure actual lane
width. The system assumes a fixed lane
width . Detection in the left and right lanes
i s based on this assumed lane width .
When dr iv ing on narrow roads or when
driving to the left or right of the center of
a travel lane, it is possib le that vehicles
will be detected that are
not in the lane
next to the lane you are using
.:!> page 103.
Operation
App lies to vehicles: with side assist
Side assist compares the distance and differ­
ence in speed of detected vehicles with the
speed of your vehicle . Whenever the d iffer­
ence in speed and distance is registered as no­
table if you were to change lanes, a signal
light appears on the respective m irror. ..,.

104 Audi side assist
right of your travel lane, depending on wheth­
er you drive in the center of your lane or closer
to the edge.
If you drive in narrow lanes, s ide ass ist's de­
tection a rea may a lso include other lanes -es­
pecia lly if you tend to drive on the edge of
your lane¢
fig. 108. Under these cond it ions ,
vehicles can also be detected that are two lanes away, and side assist then could switch
between the informat ional and warn ing stage
signals .
When driving in very w ide lanes, vehicles in
the adjacent lane may not be detected be­
cause they are not inside the detection area.
Notes
Messages in instrument cluster display
Applies to vehicles: with side assis t
If side assist turns off automatically, the indi­
cator light on the button wi ll go out and you
will see a message in the instrument cluster
d isplay:
Audi side assist: not available. sensors
blocked
The side assist sensors are built into the rear
bumper on the left and right (not visible on
the outside)
¢ page 98, fig. 99 . To ensure that
you do not adversely affect the way side assist
functions, foreign objects (such as stickers or
b icycle racks) should not be attached to the
a rea on the rear bumper where the sensors
are located. If side assist functions are ad­
ve rsely affected, you will see this message in
the instrument cluster display. Remove any ­
thing that may be blocking the sensors .
If no vehicl e is detected for a longer period of
time while driving, side assist will also switc h
off a utomatica lly.
Audi side assist currently not available
If there is a temporary problem (such as the
ve hicl e's battery charge being low), s ide ass ist
cannot be activated tempo rari ly.
Audi side assist: system fault
Have the system checked by an authorized Au­
di dealer or qualified workshop.
Audi side assist: not available when
towing
The radar senso r's view is limited when tow ­
ing a trai le r. F or vehicles with a factory instal­
l ed towing hitch or a trailer hitch that was in­
sta lled later according to factory specifica­
tions, side assist is automatically deactivated as soon as the electrical connection to the
trailer's electrical socket is made, and this sta­
tus message appears in the instrument clus ­
ter display . Deactivation cannot be guaran­
teed when using a retrofitted towing hitch
that was
not installed acco rding to facto ry
specifications.
Safety tips
Appl ies to vehicles : wi th side assist
The side assist detection may be limited when
driv ing aro und narrow street corners, on hilly
streets, and under poor weather cond itions.
It is possible that the radar sensors may also
detect other objects, such as high or stag­
gered guardrails .
Side assist does not measure actual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
o n this ass umed lane width . When driving on
narrow roads or when driv ing to the left or
right of the center of a trave l lane, it is poss i­
ble that vehicles will be detected that are
not
in the lane next to the lane you are using.
A WARNING
- Improper reliance on the side assist sys­
tem can cause collis ions and serious per­
sonal injury:
- Never rely on ly on side assist when
changing lanes .
- Always check rear view mirrors to make
sure that it is sa fe to change lanes.
- Side assist cannot detect all vehicles un-
der all conditions- danger of accident! ..,.

-Side assist cannot detect vehicles in time
to alert you when they approach from
behind at very high speed, or fall drop
back very quickly .
- The radar sensor 's
vision can be reduced
or entirely blocked by rain, snow, and
heavy spray . This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the direction you are traveling and the relevant area
around the vehicle.
- Please note that side assist indicates
there are approaching vehicles, or vehi­
cles in your blind spot, only after your ve­
hicle has reached a driving speed of at
least 19 mph (30 km/h).
- Side assist signal does not work around
tight corners (turning radius less than
328 feet, or 100 m).
- Side assist is no replacement for the driv­
er's full attention. The driver alone is re­
sponsible for lane changes and similar driving maneuvers. Always keep an eye
on the direction you are traveling and the
relevant area around the vehicle.
(D Note
To ensure that side assist is not adversely
affected, you should not block the area on
the rear bumper where the radar sensors
are located with foreign objects (such as
with stickers or bicycle racks).
If the positions of the radar sensors have
been changed as a result of a rear end-col­
lision, for instance, have side assist
checked by an authorized Audi dealer for
safety reasons.
