ment such as power w indows.
- Please note that the brake booster and
power steering only work when the en­
gine is running. When the engine
off, you
must use more force to steer or brake
the vehicle . Because the usual steer ing
and brak ing capability is not avai lable,
the risk of accidents or injur ies increases .

and heavy eng ine load as long as the en ­
gine has not reached operat ing tempera­
ture yet. You could damage the engine .
- The engine cannot be started by pushing

Steering lock1
)
The steering locks when you turn the engine
off using the
I START ENGINE STOPI* button,
move the selector lever into the P position
and open the driver's door.
The locked steering helps prevent vehicle
theft.
Emergency off function
If it is absolutely necessary, the engine can al­
so be turned off while driving at speeds lower
than 6 mph (10 km/h).
If you press the
I START ENGINE STOPI* button while driving,
the message

appears. To
switch the engine off, press the
I STAR T ENGINE STO PI* button twice in a row
briefly or press and hold for longer than two
seconds.
A WARNING
- Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the power steering is not guaranteed. You
must use more force to turn or brake, if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to accidents and serious injuries .
- Please note that the brake booster and
power steering only work when the en­
gine is running. When the engine off, you
must use more force to steer or brake
the vehicle. Because the usual steering and braking capability is not available,
the risk of accidents or injuries increases.
- Always take the vehicle key with you when leaving the vehicle, even for a
short period of time. This applies partic­ ularly when children remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
- For safety reasons, always park the vehi­
cle with the selector lever in the P posi-

tion. Otherwise, there is the risk that the
vehicle could roll.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes - even with the ignition
switched off. It can also switch on again
after some time if the coolant tempera­
ture rises as a result of heat buildup or if
the engine compartment is heated by sunlight and the engine is hot.
(D Note
If the engine has been under heavy load
for an extended period of time, heat builds
up in the engine compartment after the
engine is switched off - there is a risk of
damaging the engine. For this reason, let
the engine run for at idle for approximate­
ly two minutes before shutting it off.
Starting the engine if there is a
malfunction
Applies to vehicles: with convenience key
It may not be possible to start the engine un­
der certain circumstances, for example if the
battery in the vehicle key is drained, if inter­
ference is affected the key or if there is a sys­
tem malfunction.

designed to prevent the vehicle from rolling unintentionally and replaces the hand brake.
I n addition to the normal functions of a tradi­
tional hand brake, the electromechanical parking brake provides various convenience
and safety functions.
When starting from a stop

dr iving by automatically releasing the park­
ing brake ~
page 83, Starting from a
stop .
-When starting on inclines, the hill start as­
sist prevents the vehicle from unintentional­
l y rolling back. The braking force of the
parking brake is not released until sufficient driving force has been built up at the
wheels.

• Tap the swit ch to display the current set dis­
t ance
¢f ig. 92.
• To increase or reduce the distance in incre­
ments, tap the switch again to the right or
left . The distance between the two vehicles
will change in the instrument cluster dis­
play.
When approaching an object detected ahead,
the adaptive cruise con trol system brakes to
match that object's speed and then reg ulates
to the stored distance . If the object detected
ahead acce lerates, adapt ive cruise control will
a lso acce lerate up to the stored speed .
The highe r the speed, the greater the distance
in meters
c::;, & . The Distance 3 setting is rec­
ommended. That is equal to the general rec- ommendation of "hal
f the speed shown on
the speedometer".
T he distances provided are example values.
Depending on the driv ing s ituation, the cur­
rent speed and the way the object detected
ahead is driving, the actual distance may be
more or less than these target distances.
o:::::::, _o:::::::, ___ Distance 1: This setting cor re-
sponds to a distance of 92 feet

A WARNING
--
- Driving too close to other vehicles in­
creases the risk of collisions and ser ious
in jur ies.
- Sett ing short distances to vehicles ahead
reduces the distance and time that you
have to stop your vehicle safe ly . This in ­
creases the need for you to pay attention
to traffic.
- Always follow applicable traff ic laws , use
common sense and select a distance to
veh icles ahead that takes the current
traffic , road and weather conditions into
account.
{i) Tips
Distance 3
is set automatically each time
you switch the ignition on.
It you would
lik e to have this distance as a basic setting,
you can have the
adaptive cruise control
menu extended/ enabled from an author ­
ized repair facility .

-In some 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.
- Audi side assist cannot detect all vehicles
under all conditions, which can increase
the risk of accidents.
- Please note that side assist only displays approaching vehicles or vehicles in your
blind spot if your vehicle is traveling at
least 19 mph (30 km/h).
- In certain situations, the system may not
work or its function may be limited. For
example:
- The display may not turn on at the
right time if vehicles are approaching
or passing very quickly.
- In poor weather conditions, such as
heavy rain, snow or fog.
- In very wide lanes, in tight curves or
when there are slopes in the roadway,
vehicles in the neighboring lanes may not be detected because they are out­
side of the sensor range.
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody. This can affect the system. Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion.
@ Tips
- If the window glass in the driver's door
or front passenger's door has been tint­
