- When the veh icle is locked, no one -pa rtic u­
larly not chi ldren should rema in in the vehi­
cle. Locked doors make it more d ifficult for
emergency workers to get into the vehicle -
putting lives at risk .
Starting from rest
The starting assist function ensures that the
parking broke is released automatically upon starting.

" When you sta rt to drive as usua l, the par king
brake is automatically released and your vehicle
beg ins to move.
When stopping at a traffic signa l or stopping in
city traffic, the parking brake can be applied. The
vehicle does not have to be held with the foot­
brake . The parking brake eliminates the tendency
to creep w ith a dr ive range engaged. As soon as
you drive off as usual, the parking brake is re ­
leased a utomat ically and the vehicle starts to
move .
Starting on slopes
When starting on incl ines, the sta rting assist pre­
vents the vehicle from un intent iona lly rolling
back. The braking force of t he parking brake is
not released u nti l sufficient dr iv ing force has
been built up at t he wheels .
(D Tips
Fo r safety reasons, the park ing brake is re­
l eased automatically only when the driver's
safety be lt is e ngaged in the b uck le.

'SI: .... .... Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
11-Keep the sw itch<®) pulled and depress the ac­
celerator. The parking brake stays applied and
prevents the vehicle from rolling backward .
11-You can release the switch© once you are su re
that you a re deve loping enough forwa rd mo­
mentum at the whee ls as you depress the ac­
celerator .
Depending on the weight of the rig (vehicle and
trailer) and the seve rity of the incline, you may
roll backwards as you start. You can prevent roll­
ing backwards by holding the parking brake
switch C®> pulled out and accelerating -just as
you would when starting on a hill with a conven­
tional hand brake.
Emergency braking
In the event that the conventional brake system
fails or locks.
11-In an emergency, pull the sw itch<®) and contin­
ue to pull it to s low your vehicle down with the
parking brake.
11-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 emergency
braking function is in itiated. The vehicle is braked
at all four wheels by activating the hydrau lic
brake system . The brake performance is sim ilar
to making an emergency stop¢,& .
In order not to activate the emergency brak ing by
mistake, an audib le warning tone (bu zzer)
sounds when the sw itch(®) is pu lled . As soon as
the switch(®) is released, or the accelerator pedal
i s depressed, emergency braking stops .
A WARNING
Emergency braking should only be used in an
emergency, when the normal foot brake has
fai led or the brake pedal is obstructed. Using
t he parking brake to perform emergency
braking will slow your vehicle down as if you
D riving
had made a full brake applicat ion . The laws of
physics cannot be suspended even with ESC
and its associated components (ABS, ASR,
EDL). In corners and when road or weather
conditions are bad, a full brake application
can cause the vehicle to skid or the rear end to
b reak away -risking an acc ident.
Start/Stop system
Description
Applies to: vehicles with Start-Stop-System
The Start-Stop -System can help increase fuel
economy and reduce CO2 emissions.
In the Start-Stop-mode, the engine shuts off au­
tomatica lly when the vehicle is stopped, such as
at a traffic light . The ign ition remains switched
on during this stop phase. The eng ine will be au­
tomat ically restarted when needed.
The last Start-Stop-System setting (on/off using
the b utton
10 -I) will be restored when the igni­
t ion is turned on. The LED in the
10 ~1 button turns
on when the Start-Stop-System is switched off
manually .
Basic requirements for the Start-Stop mode
-The driver's door is closed.
- The driver' seat belt is latched .
- The hood is closed.
- The vehicle must have bee n driven faster than
2.5 mph (4 km/h) since the last stop.
- A trailer is not hitched to the vehicle .
A WARNING
-
-Never let the vehicle roll with the engine
switched off. You could lose contro l over the
veh icle. Th is can lead to a collision and seri­
ous injuries .
- The brake booster and the steering support
do not work while the engine is switched
off . More force is required to stop and to
steer the vehicle.
- To reduce the risk of injur ies, ma ke sure that
the Sta rt-Stop-System is turned off when
working in the engine compartment

Additional information
The engine will switch off in the P, D, N and S po­
sitions as well as in manual mode. In the P posi­
tion , the engine will also remain off if you take
your foot off the brake pedal. The eng ine starts
again when you select another selector lever po­
sition and take your foot off the brake pedal.
If you select the R position during a Stop phase,
the engine will start again.
Shift from D to P quickly to prevent the engine
from starting unintentionally when shifting
through R.
You can determine for yourself if the engine will
stop or not by reducing or increasing the amount
of force you use to press the brake pedal. For ex­
ample , if you only light ly press on the brake ped­
al in stop-and and-go traffic or when turning, the
engine will not switch off when the vehicle is sta-
86
tionary. As soon as you press the brake down
harder, the engine will switch off.

Before each stop phase, the system checks if cer­
tain conditions have been met. For example, the
engine will
not be switched off in the following
situations :
- The engine has not reached the minimum re­
quired temperature for Start-Stop-mode.
- The interior temperature selected by the A/C
system has not been reached .
- The outside temperature is extremely high/low.
- The windshield is being defrosted

The stop phase is interrupted in the following sit­
uations, for example . The engine restarts without
any action by the driver .
- The interior temperature varies from the tem-
perature selected in the A/C system. ..,.

Audi active lane assist Lane assist
Description
Applies to: veh icles with act ive lane assist
Active lane assist helps you keep your vehicle in
your lane .
Active lane assist detects lane marker lines with­
in the limits
of the system using a camera in the
windshield. If you are approaching a detected lane marker line and it appears likely that you
will leave the lane , the system will warn you by
means of correct ive steering . T he dr iver can over­
ride the correct ive steering at any time. If the ve­
h icle crosses a line, the drive r is also warned by a
light
vibration in the steering wheel. The vibra­
tion warning must be switched on in the MMI for
this to happen. Active lane assist is operable
when the line marking the lane is detected on at
least one side of the vehicle.
The system is designed for driv ing on freeways
and expanded highways and thus works only at
speeds of 40 mph (65 km/h) or more.
Applies to vehicles with side assist* : If you acti ­
vate your turn signal when active lane assist is
ready and when activated side assist has class i­
fied a lane change as critical because of vehicles
traveling alongside you or coming closer, there
will be noticeable corrective steering just before
you leave the lane . Th is is done to try to keep
your veh icle in the lane .
Applies to vehicles without side assist*: when the
system is ready, it does not warn you if you acti ­
vate your turn signal before driving across a lane marker line. In th is case, it assumes that you are
changing lanes intent ionally.
If the vehicle is also equipped with Audi adaptive
cru ise control*, the corrective steering w ill be
more spec ific in regard to the driving situation .
I n addition to the lane marker lines, the system
can also take into acco unt other objects such as
guard rai ls. If they are detected in close prox imi­
ty to the vehicle, Audi active lane assist helps
prevent the vehicle from driv ing too close to
them. There is also passing assistance . The sys-
Audi act ive lane ass ist
tern does not provide any corrective steering if it
detects that you are passing another vehicle .
A WARNING
--The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can assist the dr iver in keeping
the vehicle in the lane, but it does not steer
by itself . Always keep your hands on the
steer ing wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking .
- The camera does not recognize all lane
marker lines. Correct ive steering can only
take place on the side of the vehicle where
lane marker lines are detected.
- Other road structures or objects could poss i­
b ly be identified un intentionally as lane
marker lines. As a result, co rrective steering
may be unexpected or may not occ ur.
- The camera view can be restricted, for ex­
ample
by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. This can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly .
- Unde r certain condit ions such as r uts in the
road, a banked roadway or crosswinds, the
correct ive steer ing alone may not be enough
to keep the vehicle in the lane.
- For safety reasons, active lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the
potential for hydrop lan ing . Using active lane
assist u nder these condit ions may i ncrease
the risk of a crash.

Driving settings
Introduction
Aud i drive select makes it possib le to experience
d ifferent types of veh icle sett ings in one veh icle.
The driver ca n select three
Comf ort, Aut o and
Dyn am ic modes in the MMI to switch between a
sporty and a comfortable driving mode.
You can a lso adjust the setting accord ing to your
p references in the
indi vidual mode. For example,
you can combine settings such as a sporty engine tuning with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and serious
personal injury.
Description
-
The follow ing systems are affected by drive se­
lect:
Engine and t ransm is sion
Depending on the mode, the engine and the
transmission respond quicker or in a more ba l­
anced manner to accelerator pedal movements.
In the sporty dynamic mode, the transmission
shifts at h igher RPMs.
Air suspe nsion
The adaptive air suspension/adaptive air suspen­
sion sport*
(Air suspension in the MMI) is an
electronically controlled air suspens ion and
damping system . They are adjusted depending
on the se lected dr iving mode, the driver's steer­
ing, b raking and acceleration input and the road
surface, vehicle speed and load. A spo rty setting
is gene rally used in veh icles with adaptive air sus­
pens ion sport*.
The vehicle clearance va ries depending on these­
lected mode and the speed .
The highway setting is activated automatically
when yo u drive above 75 mph (120 km/h) for
mo re than 30 seconds in the
au to or dynamic
106
mode. The ground clea rance is increased auto ­
matically if the speed drops below 44 mph (70
km/h) for more than 120 seconds.
Steering
The steering adapts in terms of steering effort
and steering rat ios. Indirect stee ring that moves
easily, like the steering in com fort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering .
The following app lies to veh icles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the dr iver at a ll times . This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, however, steering is more d irect in order to keep t he steering effort as
min imal as possible whe n the dr iver is maneuve r­
i ng the vehicle. A t low and ave rage speeds, dy­
namic steeri ng addit ionally prov ides more re ­
spons ive steering performance.
Sport differential*
As a component of the all whee l dr ive sys tem
(quattro)
~ page 195, the Sport differe ntia l*
dist ributes t he d riving powe r to the rear axle de ­
pend ing on the s ituation. The distr ib ution of
power va ries depending on the selected mode,
from ba lanced (comfort) to agile (dynamic). The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.
Cur ve light *
The curve light adapts to driving on curves . The
pivoting action and the lighting are also adapted
to the mode.
Adapt ive cruise control*
The behavio r whe n accelerating ca n be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise contro l also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner . ..,_
