82 Driving
Starting from a stop
The start assist function ensures that the
parking brake is released automatically upon
starting.

.. Pull the switch@¢
page 80, fig. 73 to set
the parking brake.
St arting a nd aut omaticall y relea sing the
pa rking br ake
Requirement: The driver's door must be
locked and the driver's safety belt must be
fastened.
.. When you press the accelerator pedal, the
parking brake is automatically released and
your vehicle begins to move.
When stopping at a traffic signa l or stopping
in city traffic, the parking brake can be ap­
plied. The vehicle does not have to be held
with the brake pedal. The parking brake elim i­
nates the tendency to creep when a selector
l ever pos ition is engaged . As soon as you
press the accele rator pedal, the parking bra ke
re leases automatically and the veh icle starts
to move.
Starting on slope s
When starting on incl ines, the hill start ass ist
prevents the vehicle from unintentiona lly roll­
i ng back. The braking force of the parking
brake is not released until sufficient dr iving
force has been bu ilt 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 sa fety belt is fastened and the driver 's
door is locked. Emergency braking function
This is used if the conventional brake system
fails or locks up .
.. To brake your vehicle in an emergency, pull
the @switch ¢
page 80, fig. 73 and hold it
pulled .
.. As soon as you release the@ switch or ac-
celerate, the b rak ing process stops.
Pul ling and ho ld ing the @switch while dr iv ­
ing at a speed of about 2 mph (3 km/h) or
higher init iates the emergency braking func­
t ion. The vehicle is braked at a ll four wheels
by activating the braking hyd rauli cs . The brake
performance is sim ila r to heavy braking.
~ .&.
To he lp prevent activating the emergency
braking by mistake, a n aud ible war ning tone
(buzzer) sounds when the @switch is pulled .
Emergency brak ing stops as soon as the@
swi tch is re leased or the acce lerator pedal is
pressed.
.&, WARNING ,_
Emergency braking should only be used in
an emergency, when the normal brake pedal has fa iled or the brake pedal is ob­
structed. During emergency brak ing, your
vehicle will brake s imilar to heavy b rak ing .
E SC and the associated components (ABS,
ASR, EDL) canno t overcome the laws of
physi cs. In corne rs and when road or
weather conditions are bad, a fu ll brake
application can cause the vehicle to skid or
the rea r end to break away, which increas­
es the risk of an accident.
Hill hold
Applies to veh icles : w ith Hill Hold
Hill hold makes it easier to start on hills.
Req uirement: The dr iver door mus t be closed
and the engine must be running.
T he system is activated when the bra ke peda l
is p ressed while the vehi cle is stationa ry.

second.
To keep shifting using the shift paddles, move
the selector lever to the rig ht out of the D/
S position into the tiptronic shift gate.
The transmission automatically shifts up or
down before critical engine speed is reached.
T he transmission only allows manual shifting
when the engine speed is within the permit­
ted range.
(D Tips
- If you shift to the next lowest gear, the
transmission w ill only shift if the engine
will not be over-revved.
- With kick-down, the transmission shifts
to a lower gear, depending on vehicle
speed and engine speed.
- tiptronic does not work if the transmis­
sion is run ning in emergency mode.
· Kick-down
App lies to vehicles: wit h S t ronic tra nsmi ssio n
Kick-down enables maximum acceleration.
When yo u press the accele rator pedal down
beyond the resistance point, the automatic
transmission downshifts into a lower gear, de­
pending on vehicle speed and engine RPM. It
shifts up into the next higher gear once the
maximum specified engine RPM is reached.
A WARNING
-Please note that the wheels could spin on
slick or slippery roads when kick-down is
active.

190 Smart Technology
Steering r ecommendat ion
The ESC helps to stabilize the vehi cle by
changing the steering torque.
Select ive wh eel torqu e co ntrol
Select ive wheel torque control is used when
driving on curves . The front wheel on the in ­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
Th is a llows more precise driv ing in c urves.
Automatic post -collision braking system
The "Automatic post-collision braking system"
can he lp to reduce the risk of sliding and of
other coll is ions after an acc ident. If the airbag
control mod ule detects a collision above acer­
tain vehicle speed, the vehicle is braked by the
ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal , or
- the braking fo rce genera ted by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle
electrical system are not functioning .
A WARNING ,.
- The ESC and its integrated systems can­
not overcome the lim its posed by natural
physical laws. This is especia lly impor­
tant on s lippery or wet roads. If the sys-
Switching on /off
terns begin acting to stabilize your vehi­
cle, you should immediately a lter your
speed to match the road and traffic con­
ditions . Do not let the increased safety
provided tempt you into taking r isks .
This could increase your risk of a co lli­
sion .
- Please note the r isk of a coll is ion increas­
es when driving fast, especially through
curves and o n slippe ry or wet roads, and
when dr iv ing too close to objects ahead.
The ESC and i ts integrated systems can­
not a lways p revent collisions -there is
still a risk of accidents!
- Press the acce lerator pedal caref ully
when acce lerating on even, slippery sur­
faces such as ice and snow. The drive wheels can spin even when these control
systems are installed and this can affect
driving stability and increase the risk of a
coll is io n.
(D Tips
- ABS and ASR only function correctly
when all four wheels are equ ipped w ith
identical t ires . Different t ire sizes can
lead to a reduction in engine power.
- You may hear noises when the systems
descr ibed are working .
- If the
DJ or [IJ indicator light appears,
there may be a malfunction¢

Fig. 1 50 Upper c ente r conso le : ESC but to n
The ESC is designed to funct ion in levels . De­
pending on the level that is selected, the sta­
bilization funct io n of the ESC is lim ited or
swit ched off . The amoun t of stabilization con ­
tro l will differ depending on t he level.
In the follow ing unusual situations it may
make sense to switch the ESC sport mode on
to allow the wheels to sp in:

ally, bra ke in intervals and not continu­
ously.
(D Tips
- If the brake boos ter is not wor king, you
must p ress the brake pedal with much
more force t hen no rma l.
- If yo u retrof it your vehicle with a front

ALL wheel drive
(quattro)
App lies to vehicles: wi th all wheel drive
In all wheel drive, all four wheels are pow­
ered.
General information
In all whee l dr ive, the dr iv ing power is divi ded
between all fo ur whee ls. Thi s happens auto ­
matically depending on yo ur driv ing behavior
as well as the current road conditions. Refer
to
¢ page 189, Electronic stabilization con­
trol (ESC) .
The all wheel drive concept is designed for
high eng ine power. Your veh icle is except ion­
a lly powerfu l and has excellent driving charac­
te ristics both under normal driv ing cond itions
and on snow a nd ice. Always read and follow
safety precaut ions¢ .&.. ..,.

194 Smart Technology
Winter tires By using all wheel drive, your vehicle has good
forward motion with standard tires in winter
cond itions. However, in winter we recommend
using winter or all season tires on
all four
wheels, because this will improve the braking
effect .
Snow chains
If there are snow chain laws, snow chains
must also be used on vehicles with all whee l
drive ¢
page 262, Snow chains .
Replacing tires
Fo r vehicles w ith all whee l dr ive , only wheels
with the same rolling circumference should be
used . Avoid whee ls with different tread
depths ¢
page 254.
Offroad vehicle?
Your Aud i is not an offroad vehicle -there is
not enough ground clearance. For this reason,
avoid difficult terrain. Refer to¢
page 287.
&_ WARNING
- Also, in vehicles with all whee l dr ive,
adapt yo ur driving style to the current
road and traffic conditions. Do not let
the increased safety provided tempt you
into taking risks.
- The braking ability of your vehicle is lim­
ited to the traction of the wheels . In this
way, it is not different from a two wheel
dr ive vehicle. Do not be tempted to ac­
celerate to a high speed when the road is
slippery this increases the risk of an acci­
dent .
- Note that on wet streets, the front
wheels can "hydroplane" if driving at
speeds that are too high. Unlike front
wheel drive vehicles, the engine does not
rev higher suddenly when the vehicle be­
gins hydroplan ing. For this reason, pay
attention to the road conditions regard­
less of your speed.
Energy management
The starting ability is optimized
The energy management system manages
the electrical energy distribution and optimiz ­
es the availability of electrical energy for
starting the engine.
When a vehicle with a conventional energy
system is not driven for a long time , the bat­
tery is drained by equ ipment (for example the
immobilizer). In certain circumstances, there
could may not be enough energy to start the
engine .
Your vehicle is equipped with an intel ligent
energy management system for d istr ibut ing
electricity. This s ignificantly improves the
sta rting ability and increases the battery life.
The energy management sy stem Is made up
of
battery diagnosis , idling current manage·
ment
and dynamic energy management .
Battery diagnosis
The battery d iagnosis determ ines the battery
charge leve l. The sensors determine the bat­
tery voltage, the battery current, and the bat­
tery temperature. The curren t cha rge leve l
and the performance of the battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used wh ile parked. With the engine
switched off, it manages the energy distribu­
tion to the different elect rical componen ts.
Date from battery diagnosis is taken into ac­
count for this.
Depending on the battery charge level, elec­
trical equip ment is switched off one item after
the o ther, to prevent the battery from drain­
ing and to retain the starting ability.
Dynamic energy management
While driving, dynamic energy management
distributes the appropriate amount of energy
to the e lectr ica l equipment.
It controls the
battery charge level so that more energy is ..,.
