matically or it may continue to run (even if
the is ignit ion sw itched off) due to the follow­
ing reasons :
- The coolant temperat ure is increasing due
to trapped heat.
- If the engine is warm and the engine com­ partment also heats up from strong sun ­
li ght .

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 Start/Stop mode, the engine shuts off auto ­
matically when the vehicle is stopped, such as at
a traffic light. The ignition remains switched on
during this stop phase. The engine w ill restart
automat ically when needed.
The Start/Stop system is automat ically act ivated
as soon as the ignition is switched on.
Basic requirements for Start/Stop mode
-The driver's door must be closed .
- The driver's seat belt much be fastened.
- The hood must be closed.
- The vehicle must have driven faster than
2 mph
(3 km/h) since the last time it stopped.
(D Note
Always switch the Start/Stop system off when
driving through water
r:> page 83.
(D Tips
The engine stops shortly before the veh icle
comes to a stop
l). The full function of the
brake booster and the power steering is still
available.

In addition to releasing the parking brake auto­

Starting from a stop.
Preventing the automatic parking brake
release
The vehicle could begin rolling unintentionally,
dep ending on the hill or if towing a trailer.
"'To prevent the parking brake from releasing au­
tomatically, pull and hold
the®> switch and
press the accelerator pedal. The parking brake
remains set and prevents the vehicle from roll­
ing backward.
"'You can release the(®) switch again once you
are sure that you are giving enough driving
force to the wheels by pressing the accelerator pedal.
Emergency braking function
You can use the emergency braking function in an emergency situation, or if the standard brake op­
eration malfunctions or is disabled .
"'Pull and hold the(®) switch.
"' As soon as you release the ®> switch or acceler-
ate, the braking stops .
Pulling and holding
the®> switch while driving
the vehicle activates the emergency braking func­
tion . The vehicle is braked at all four wheels by
activating the hydraulic brake system. The brak­ ing effect is similar to heavy
braking ¢,&. .
To reduce the risk of activating the emergency
braking by mistake, a warning tone (bu zzer)
sounds when
the(®) switch is pulled. Emergency
braking stops as soon as
the(®) switch is released
or the accelerator pedal is pressed .
Parking
"' Press the brake pedal to stop the vehicle.
"'Pull the®> switch to set the parking brake.
"'Place the selector lever in the P position.
"'Turn the engine off ¢,&. .
84
"'Turn the steering wheel when parking on in­
clines so that the wheels will roll into the curb
if the vehicle starts moving.
A WARNING
- Do not press the accelerator pedal inadver­
tently if a gear is selected when the vehicle
is stationary and the engine is running . Oth ­
erwise, the vehicle will start to move imme­
diately and this could result in an accident.
- Emergency braking should only be used in
an emergency, when the normal brake pedal has failed or the brake pedal is obstructed.
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics. In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which increases the risk of an accident.
- If the power supply fails, you cannot set the
parking brake if it is released . In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
-Always take the vehicle key with you when
leaving your vehicle, even for a short period
of time . This applies particularly when chil­
dren remain in the vehicle. Otherwise chil­
dren could start the engine, release the
parking brake or operate electrical equip­
ment such as power windows, which in­
creases the risk of an accident.
- No one should remain in the vehicle when it
is locked - especially children. Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk .
(D Tips
When stopping at a traffic signal or stopping
in city traffic, you can set the parking brake
manually . The vehicle does not have to be
held with the brake pedal. The parking brake
eliminates the tendency to creep when a se­ lector lever position is engaged . As soon as

CXl CXl .... N ,.__
N .... 0 N > 00
you press the accelerator pedal, the parking
brake releases automatica lly and your vehicle
starts to move ¢
page 85.
(D Tips
-Occasional noises when the park ing brake is
set and re leased are normal and are not a
cause for concern .
-The parking brake goes through a se lf-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated w ith this are
normal.
-If there is a power failure, the parking brake
will not set if it is released, and it will not
release if it is
set¢,&.. See an author ized
Audi dealer or authorized Audi Service Fa­
cility for assistance.
Starting from a stop
Various convenience and safety functions may be
ava ilable when the vehicle begins dr iv ing, de­
pending on vehicle equipment .
Starting on hills with the parking brake set
Requirement: the driver's door must be closed.
.,. To start driving comfortab ly when on a hill, set
the parking brake and begin driving as usual.
The braking force of the parking brake does not
release automatically until the wheels build up
enough driving force .
Starting on hills with hill hold assist
Hill hold assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the eng ine must be r unning.
.,. To activate hill hold assist, press and hold the
brake pedal for several seconds . The vehicle
must be in an uph ill direction of travel.
After releasing the brake pedal, the braking pow ­
er is ma inta ined for a br ief
moment ¢,& to pre­
vent the vehicle from rolling back when starting.
During this time, you can easily beg in to move
your veh icle.
Driving
A WARNING
Applies to: ve hicles with h ill ho ld assist
-I f you do not beg in driving immediate ly or
the engine stalls afte r releasing the brake
pedal, your veh icle may begin to roll back­
ward. Press the brake pedal or set the park­
ing brake immediately.
-The intelligent technology of hill hold assist
cannot overcome the limitations imposed by
natural physica l laws. The increased comfort
offered by hill hold assist should not cause
you to take safety risks.
-Hill hold assist cannot hold the vehicle in
p lace on a ll hills (for example, if the ground
is slippery or icy).
-To reduce the risk of an accident, always make sure the veh icle is situated safely
while stationary.
Automatic transmission
Introduction
Applies to: vehicles with automatic transmissions
T he automatic transmission is controlled elec­
tronically . Upshifting and downshifting occur au­
tomatica lly .
When a
moderate driving style is used, the
transm ission selects the most economica l dr iv ing
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fue l
efficiency.
In the S selector leve r pos ition, the transmission
switches to a sporty mode after a kick-down or
when the driver uses a
sporty driving style char­
acterized by quick accelerator pedal movements,
heavy acce leration , frequent changes in speed
and traveling at the maximum speed.
If desired, the driver can also select the gea rs
manually (tiptronic mode) ¢ page 90, Manual
shifting (tiptronic mode).
The S tron ic is a dual-clutch transmission. Power
is transferred using two clutches that work inde ­
pendent ly from one another. They rep lace the
torque converter used in conventional automatic

pends on engine load, vehicle speed and driving
style.
The engine 's power reserves are used fully in the
Sport mode S . Shifting may become noticeab le
when accelerating .
To move from selector lever position N to D, yo u
must press the bra ke pedal and the veh icle mus t
be traveling less than 1 mph (2 km/h) or be sta­
tionary ¢.&, .
A WARNING
Read and follow all WARNINGS.
-The vehicle can roll even if the ignition is
switched off.
-Never select R or P while driv ing, beca use
this increases the risk of an accident.
-Power is st ill transmitted to the wheels
when the eng ine is r unning at idle . To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake in all selector
lever positions (except P) when the engine is
running . Otherwise, th is increases the r isk
of an accident .
-Do not inadvertent ly press the acce lerator
peda l when the veh icle is stopped if a gear is
engaged . Otherwise the veh icle wi ll start to
