If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the eng ine about 30 seconds later .
After a cold engine is star ted, there may be a
brief period of increased noise because oil
pressure must first bui ld up in the hydraulic
va lve adjusters. This is normal and not a cause
for concern.

A WARNING
- Never a llow the engine to run in confined
spaces - danger of asphyx iation.
- Never turn off t he engine until the vehi­
cle has come to a complete stop.
- The brake booster and servotron ic only
work when the engine is runn ing . With
the ignition turned off, you have to apply
more force when steering or brak ing.
Since you can not steer and stop normal ­
ly, th is can lead to acc idents and serious
in ju ries .
(D Note
-Avo id h igh engine rpm, full thrott le and
heavy engine loads until the eng ine has
reached operating temperature - other-
w ise you risk engine damag e.
- T he engine cannot be started by pushing
o r towing the vehicle.
Ill-

98 On the road
-When the vehicle is locked, no one - par­
t icu larly not ch ildren should remain in
the vehicle. Locked doors make it more
difficult for emergency workers to get in­
to the vehicle - putt ing lives at risk.
Starting from rest
The starting assist function ensures that the
parking brake is released automatically upon
starting .
Stopping and applying parking brake
.. Pu ll the switch to apply the parking brake.
Starting and automatically releasing the
parking brake
.. When you start to drive as usua l, the park­
ing brake is automatically re leased and your
vehicle begins to move.
When stopping at a traffic signal or stopping
in city traffic on vehicles with an automatic
transmission, the park ing brake can be ap­
plied. The veh icle does not have to be held
with the footbrake. The park ing brake elimi­
nates the tendency to creep with a drive range
engaged. As soon as you dr ive off as usual,
the park ing brake is released automatically
and the veh icle sta rts to move.
Starting on slopes
When starting on inclines, the start ing ass ist
prevents the vehicle from unintentionally roll­
i ng back . The braking force of the parking
brake is not released until sufficient dr iving
fo rce has been built up at the whee ls.
(D Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er 's safety belt is engaged in the buck le.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
• Keep the switch pulled and depress the ac­
celerator . The parking brake stays applied
and prevents the vehicle from roll ing back ­
ward .
• You can re lease the switch once you a re sure
that you are developing enough driving
force at the wheels by depressing the accel­
erator.
Depending on the weight of the rig (vehicle
and t railer) and the severity of the incline, yo u
may roll backwa rds as you start . You can pre­
vent rolling backwards by holding the parking
brake switch pulled out and accelerating -just
as you would when starting on a hill with a
convent ional hand brake.
Emergency braking
In the event that the conventional brake sys­
tem fails or locks.
.. In an emergency, pull the switch and con­
tinue to pull it to slow your vehicle down
w ith the park ing brake.
• As soon as you release the switch or acceler-
ate, the brak ing process stops.
If you pull the switch and hold it above a
speed of about 5 mph (8 km/h), the emergen­ cy brak ing funct ion is initiated . The vehicle is
braked at all four wheels by activating the hy­
draulic brake system . The brake performance
i s sim ilar to making an emergency stop~& .
In order not to act ivate the emergency brak­
i ng by mistake, an audib le warning tone (buz­
zer) sounds when the switch is pulled. As soon
as the switch is re leased, or the accelerator
pedal is depressed, emergency braking stops.
A WARNING
Emergency braking should only be used in
an emergency, when the norma l foot brake
has failed or the brake pedal is obstructed. .,..

react when you drive towards an obstacle
or something else on or near the road
t h at is not moving, such as vehicles stop­
ped in a traffic jam, a stalled or disabled
vehicle .
- Always remember that the adaptive
cruise control cannot detect a vehicle
that is driving towards you in your traffic lane and that it cannot detect narrow ve­
hicles such as motorcycles and bicycles.
(D Tips
- Fo r safety reasons, the stored speed is
deleted when the ignition is turned off .
- The Electronic Stabilization Program
(ESP) and the Anti-Slip Regulation (ASR)
cannot be deactivated when the adaptive
cruise control is switched on. If the ESP
and the Anti-Slip Regulation (ASR) has been deactivated and you then switch on
the adaptive cruise control, the ESP func­
tion will also be activated automatically.
- Damage caused by accidents (e.g. if the
vehicle is damaged when parking) can af­
fect the radar sensor settings. This can
cause the system to malfunction or
switch off complete ly.
- The radar sensor cover is heated. In win­
ter cond itions, you should still check be­
fore driving to make sure it is free of ice
and snow. If necessary, clean the area
near the radar sensor carefully
9 fig. 110.
-To ensure that the radar sensor is not
blocked, foreign objects (e.g . stickers,
add-on parts) must not cover the area near the radar sensor
9 fig. 110. The
area near the radar sensor must not be painted, either.

Adaptive cruise control 103
How does adaptive cruise control work?
App lies to veh icles: w ith adaptive cru ise control
Vehicles traveling ahead are detected with
the aid of a radar sensor.
Fig. 111 Radar sensor measu re m ent range
A radar sensor is built into the front of the ve­
hicle
9 fig. 111, which is subject to certain
system limits~
page 112. Stationary objects
are not taken into consideration. The system
is intended to measure the distance to reflec­
tive surfaces. The system responds after the
distance measurement has taken place. If a
measurement is not possible, the system does
not respond .
Open road
When the road is clear, the adaptive cruise
control works like cruise control. It maintains
a constant target speed specified by the driv­
er.
Driving in traffic
If a vehicle driving ahead is detected, the
adaptive c ruise control decelerates (within the
Limits of the system)
9 page 111, Driver in­
tervention prompt
and 9 page 112, System
limitations
to its speed and after adjusting,
tries to maintain the set distance from the ve­
hicle ahead . Th e vehicle may temporarily drive
slower than the set speed while adjusting
~.&. in Description on page 102.
If the vehicle in front accelerates, adaptive
cruise control also accelerates up to the speed
that you have set.
Situation requiring driver intervention
In some situat ions you will have to use the
footbrake to slow the vehicle down in order to .,..

any objects over an extended time period. For
the time being, the distance to vehicles up
ahead is not being controlled. The ACC system
is not switched off, so increased alertness is
required. The following may be reasons for
the text message ACC Functionally limited:
- The ACC sensor is dirty. The ACC system is
not reacting, or is not reacting correctly, to
vehicles traveling ahead .
- It is possible that you are driving on a road
with very light traffic
without anything at
the side of the road (e.g. guard rails, traffic
signs, trees). As soon as a vehicle is detected
by the system again, it returns to its control
range and the text message disappears.
The ACC sensor is located in the right front
trim grille
¢ page 102, fig . 110. If there is a
loss of operation due to heavy contamination,
this area should cleaned to restore proper op­
eration.
ACC not available
The text message ACC not available appears,
for example, if the temperature of the brakes
is excessive . Adaptive cruise control is tempo­
rarily not available. A warning tone sounds as
a reminder.
ACC not available!
The text message ACC not available! appears
in the event of a malfunction. Adaptive cruise
control is turned off. A warning tone sounds
as a reminder. Have the system inspected by a
qualified dealership.
ACC sensor blocked !
The text message ACC sensor blocked ! ap­
pears when the ACC system can no longer
guarantee safe detection of objects. Adaptive
cruise control is turned off. A warning tone
sounds as a reminder.
To decide whether it is necessary to switch off
the ACC (ACC sensor blocked
!) or if it is only a
temporary condition (ACC Functionally limit­
ed), the system will also takes into considera­
tion the outside temperature and/or the wind­
shield wiper operation. The
ACC sensor is dirty or blocked (e.g. leaves,
snow).
The sensor should be cleaned to restore prop­
er sensor function¢
page 102, fig. 110.
Engine speed !
The text message Engine speed ! appears in
vehicles with manual transmission when the driver did not shift up or down in time while
using adaptive cruise control braking or accel­
erating, causing the vehicle to exceed or not
reach the permitted limit speed. This causes
adaptive cruise control to deactivate automat­
ically. A chime sounds as a reminder.
Parking brake!
The text message Parking brake! appears if
emergency braking was manually initiated
with the Electromechanical Parking Brake
(EPB). The adaptive cruise control is turned
off. This is accompanied by a warning tone.
Stabilisation program
The text message Stabilisation program ap­
pears if the Electronic Stabilization Program
(ESP) has intervened. In this case the adaptive
cruise control is automatically turned off. This
is accompanied by a warning tone.
Speed
The set speed in mph (Canada km/h) always
appears when saving or changing the speed in
adaptive cruise control¢
page 104, How is
the speed stored?
and ¢ page 105, Changing
stored speed.
Speed too low
The text message Speed too low appears if
the current speed is too low
to set or to hold
the requested speed.
When setting a desired speed, it must be at
least 20 mph (30 km/h). At speeds below 12
mph (20 km/h), the cruise control is turned
off.
In speeds over 95 mph (150 km/h), the sys-
tem remains active and resumes the speed of .,..

-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 objects (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
9 page 122. The indicator light
on the button goes out .
- The area on the bumper where the radar
sensors 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 122 .
-Additional tinting on the front side w in­
dows can make it harder to see and cor­
rectly understand the signal light on the
outside mirror.

Sensor detection area
Applies to vehicles: wit h side assist
t
Fig. 133 Schemat ic illustrat ion : Sensor detect ion area
The detection¢ fig. 133 of the radar sensor
detection area is made up of:
- the approach area (light red area)
(D, about
230 feet (70 m) behind the vehicle, and
- the "blind spot" (dark red 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 driving on narrow roads o r 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 121.
Operation
App lies to vehicles: wit h side assist
Side assist compares the distance and differ­
ence in speed of detected vehicles with the
speed of your vehicle . Whenever the differ ­
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.
Ill-

122 Audi side assist
whether you drive in the center of your lane or
closer to the edge.
If you d rive in narrow lanes, side assist's de­
tection area may also incl ude other lanes -es­
pecia lly if you tend to drive on the edge of
your lane¢
fig. 139. Under these conditions,
ve hicles 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 dr iv in g 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 assist
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 s ide assist sensors are built into the rear
bumper on the left and right (not visible on
the outside)
¢page 116, fig. 130. To ensure
that you do not adversely affect the way side
assist funct ions, foreign objects (such as st ick­
e rs or b icycle racks) should not be attached to
the area on the rear bumper where the sen­
sors are located. If side assist functions are
adversely affected, you will see this message
in the instrument cluster display. Remove any ­
thing that may be blocking the sensors .
If no ve hicl e is detected for a longer period of
time while driving , side assist will also switch
off a utomatica lly.
Audi side assist currently not available
If there is a temporary problem (such as the
vehicle's batte ry charge being low), s ide ass ist
cannot be activated temporarily .
Audi side assist: system fault
Have the system checked by an authorized Au­
di dealer or qualified workshop.
Safety tips
Applies to vehicles: with side assist
The side assist detection may be limited when
driving aro und narrow street corners, on hilly
streets, and under poor weather conditions.
It is possible that the radar sensors may a lso
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
on this assumed 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
-
- I mproper reliance on the side assist sys-
tem can cause collis ion s and serio us per­
sonal injury:
- Never rely on ly on s ide assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Side assist cannot detect vehicles in time
to a lert you when they approach from
behind at very high speed, or fall drop
back very qu ickly.
- The radar sensor's
vision can be reduced
or entire ly 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.
{[) 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).
@ Tips
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.
