A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiation .
- Never turn off the eng ine unti l the vehi­
cle has come to a complete stop .
- The brake booster and power steer ing
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 stee r and brake as you usua l­
ly wou ld, this could lead to crashes and
ser ious injur ies.
- Avoid high engine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating temperat ure - ot her­
wise yo u risk eng ine dam age.
- The eng ine ca nnot be started by pushing
or tow ing the veh icle.
(D Tips
- After a cold engine is sta rted, there may
be a brief period of increased noise be ­
ca use oil p ress ure mus t fi rs t bu ild up in
the hyd raulic valve adjus ters. This is nor ­
mal and not a ca use for concern .
-If yo u leave the vehicle with t he ignit ion
switched on, the ignition will switch off
On th e ro ad 77
after a cer tain per iod of t ime. Please

- T he b rake booster and powe r stee ring
only work w he n the eng ine is r unning. 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, th is co uld lead to crashes and
serio us injuries.
- For safety reasons, you sho uld a lways
park your vehicle w ith the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away .
- After the eng ine has been switched off,
the radiator fa n can cont inue to run for
up to 10 minutes - even with the ignition
sw itche d off .
It can also sw itch on again
after some t ime if the coolant tempera­
ture r ises as the resu lt of a hea t buildup
.
or if the engine is hot and the engine .,..

soon as the switch(®) is released, or the accel ­
erator pedal is depressed, emergency braking
stops.
.&_ WARNING
Emergency braking should only be used in
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 your vehicle down
as if you had made a full brake applicat ion.
The laws of physics cannot be suspended
even with ESC 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.

Description
Appl ies to vehicles : wit h Start-Stop-System
The Start-Stop-System can help increase fuel
economy and reduce CO
2 emissions.
I n the Start-Stop-mode, the engine shuts off
automatically when the vehicle is stopped,
such as at a traffic light. The ignit io n remains
sw itched on dur ing th is stop phase. The en­
gine will be automatically restarted when
needed.
The last Start-Stop-System setting (on/off us­
ing the button
l ignition is turned on . The LED in the
l --1 but­
ton 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.
- T he veh icle must have been driven faster
~ than 2.5 mph (4 km/h) since the last stop.

.&_ WARNING
-Never let the vehicle roll with the engine
sw itched off . You could lose control over
the vehicle. This can lead to a collision
and serious injuries.
- The brake booster and the steering sup­
port do not work while the eng ine is
sw itched off. More force is required to
stop and to steer the vehicle.
- To reduce the risk of injuries, make sure
that the Start-Stop-System is turned off
when working in the eng ine compart­

Audi active Lane assist
Active Lane assist
Description
Applies to vehicles: with active lane assist
Active lane assist helps you keep your vehicle
in your lane.
Active lane assist detects lane marker lines
within the limits of the system using a camera in the windshield . If you are approaching a de­
tected lane marker line and it appears likely
that you w ill leave the lane, the system will
warn you by means of corrective steer ing . T he
driver can over ride the cor re ct ive steer ing at
any time. If the veh icle crosses a line, the d riv­
er is also warned by a light
vibration in the
steering whee l. The vibration warning must
be switched on in the MMI for this to happen.
Active lane ass ist is operable when the line
marking the lane is detected on at least one
side of the vehicle .
If the system is in active standby mode and
the turn signa l is activated before driving over
the lane marker line, the warning does not oc­
cur since the system allows for intentional lane changes .
The system is designed for driv ing on free­
ways and expanded highways and thus works
only at speeds of 40 mph (65 km/h) or more .
If the vehicle is also equipped with Audi adap­
tive cruise control*, the corrective steering
will be more specif ic in regard to the driving
situation . In addition to the lane marker lines,
the system can a lso take into acco unt other
objects such as guard rails. If they are detect­
ed i n close proximity to the veh icle, Audi a c­
tive lane ass ist helps prevent the vehi cle from
driving too close to them . The re is also pass­
ing assistance. The system does not provide
any corrective steering if it detects that you
are passing another vehicle.
A WARNING
- The system warns the driver that the ve­
hicle is leaving the lane us ing corrective
Audi acti ve lane a ssis t 95
steer ing. The driver is always responsible
for keeping the vehicle within the lane.
- The system can assist the driver in keep­
ing the vehicle in the lane, but it does
not steer by itself. A lways keep your
hands on the steering wheel.
- Corrective steering may not occur in cer­ tain sit uat ions, such as dur ing heavy
brak ing.
- The camera does not recognize all lane
marker lines. Corrective steer ing can only
take p lace on the side of the vehicle
where lane marker lines are detected .
- Other road structures or objects cou ld
possibly be identified un intent ionally as
lane ma rker lines. As a result, cor rect ive
steer ing may be unexpected or may not
oc cur .
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
r ai n, snow, heavy spray or light s hining
into the camera. This can result in a ctive
lane assist not detecting the lane marke r
lines or detect ing them inco rrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross­
winds, the corrective stee ring alone may
not be enough to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
must not be used when there are poor
road and/or weather condit ions such as
slippery roads, fog, gravel, heavy rai n,
snow and the potent ial for hydroplaning .
Using act ive lane assist under thes e con­
ditions may increase the risk of a crash.

system is ready to use . The system can now
warn you if you are about to cross a known
lane marker line .
• Not ready: The ind icator light shows that
the system is turned on but unable to send a
warning . This can be due to the following :
- There is no lane marker line .
- The relevant lane marker lines are not de-
tected (for example, markings in a construc­
tion zone or because they are obstructed by
snow, dirt, water or backlight ing).
- The vehicle' s speed is below the speed need ­
ed to activate it, which is about 40 mph (65
km/h) .
- The lane is narrower than about 8 ft . (2 .5 m)
or wider than 15 ft (4 .5 m).
- The curve is too sharp . - The driver's hands are not on the steering

A WARNING
Improper use of the A udi drive select can
cause collisions, ot her acc idents and se ri­
ous personal injury.
Description
The follow ing systems a re affected by dr ive
se lect:
Engine and transmission
Depending on the mode, the engine and the
tra nsmission respond quicker or in a more bal­
a nced manner to acce lerator pedal move ­
men ts. I n the sporty dynamic mode, the
tra nsmission sh ifts at highe r RPMs.
Air suspension*
The adaptive air suspension/adaptive air sus­
pe nsion sport*
(A ir suspension in the MMI) is
an e lec tronically con tro lled air suspens ion and
d ampi ng sys tem. Th ey are adjusted depe nd­
ing on the se lected driving mode, the dr ive r's
steer ing, br aki ng and acceler ation inpu t and
the road s urface, ve hicle speed an d load . A
sporty se tting is generally use d in vehicl es
with a daptive ai r suspension s port* .
The vehicle clea rance v aries depe nd ing on the
se lec ted mode and the speed . T
he hig hway setting is act ivated automat ically
whe n you drive above 7 5 mph (120 km/ h) for
m ore than
30 seconds in the Auto or Dynamic
mode. The g ro und clearance is increased a uto­
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 ratios. Indirect steering that
moves easily, like the steer ing in comfort
m ode, is best suited to lo ng drives o n a hig h­
way. In contrast, dynamic mode provides spo rty, direct steer ing .
The following applies to veh icles with dynamic
steering* : the steer ing rat io changes based on
vehicle speed in orde r to ma inta in optimum
stee ring effort for the dr ive r at all times . This
sets the stee ring to be less sens itive at h igher
speeds in order to provide improved vehicle
co ntrol. At reduced spee ds, howeve r, s teer ing
is mo re d ire ct in order to keep the stee ring ef ­
fort as minima l as poss ible when the drive r is
mane uve rin g the vehicle. At low and average
speeds, dynamic steering addit iona lly pro ­
vides more responsive steeri ng performance.
Sport differential*
As a component o f the all whee l dr ive system
(quatt ro)

of power var ies depending on the selected
mode, from balanced (comfo rt) to agile (dy­
nam ic) . The goal is a h igh level of ag ility and
abili ty to acce lera te on curves . Th e veh icle is
very respons ive to stee ring.
Curve light*
The curve light adapts to driving on curves.
The pivoting act io n and the lighting are also
adapt ed to the mode.
