Start/Stop system
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 stopped, for example at a traffic
light.
The ignition and important assist systems such
as the brake booster will remain available during
the Stop phase. The engine will restart automati-
cally when needed.
The Start/Stop system is automatically activated
once 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
(4 km/h) since the last time it stopped.

Z\ WARNING
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You would then need to use
more force to steer and brake the vehicle.
The fact that you cannot steer and brake as
usual may increase the risk of accidents and
serious injuries.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. This
applies particularly when children remain in
the vehicle. Otherwise the children could
start the engine or operate electrical equip-
ment such as power windows.
—To reduce the risk of injuries, make sure that
the Start/Stop system is turned off when
working in the engine compartment
> page 79.

@) Note
Always switch the Start/Stop system off when
driving through water > page 79.
Stopping and starting the engine
Applies to: vehicles with Start/Stop system
> Press and hold the brake pedal until the vehicle
has stopped. The a& indicator light

appears in the instrument cluster once the en-
gine stops automatically.
> The engine starts again when you remove your
foot from the brake pedal. The indicator light
turns off.
Additional information for automatic
transmissions
The engine stops in the "P", "N" and "D" selector
lever positions.
If you select the “R” gear during a Stop phase
while pressing the brake pedal, the engine will
start again.
Shift to "P" quickly to prevent the engine from
starting unintentionally when shifting through
"RM.
You can control if the engine will stop or not by
reducing or increasing the amount of force you
use to press the brake pedal. For example, if you
only lightly press on the brake pedal in stop-and-
go traffic or when turning, the engine will not
switch off when the vehicle is stationary. If you
press the brake pedal harder, the engine will
switch off.
@) Tips
— Press the brake pedal during a Stop phase
to keep the vehicle from rolling.
— The ignition will turn off if you press the
START ENGINE STOP] button during a Stop


phase.
— When you stop and the Start/Stop system
turns the engine off, the ignition remains
on. Make sure the ignition is switched off
before you leave the vehicle or else the bat-
tery could drain.
General information
Applies to: vehicles with Start/Stop system
Starting and stopping the engine automat-
ically
The system checks if certain conditions are met
before and during the Stop phase, and deter-
mines if the engine stops and how long it re-
mains stopped. For example, if power usage is
high, the engine will not be stopped. Along with
78
other conditions, the following factors influence
the automatic engine start or stop:
— Environmental conditions (slopes, inclines, ele-
vation, temperature)
— Battery (charge status, temperature, power us-
age)
— Engine temperature
— Assist systems
— Driving behavior
Depending on the engine, the indicator light
may appear if the engine is not stopped.
Ignition is switched off automatically
To prevent the vehicle battery from draining, the
ignition will switch off automatically under the
following conditions:
— If the vehicle has already been driven
— If the Start/Stop system has stopped the en-
gine
— If the driver's door is opened
— If the driver's safety belt is unbuckled
— If the brake pedal is not pressed
— If the vehicle is stationary
In this case, the parking lights switch on in place
of the low beams and the message Side marker
lights will switch off automatically in 30 mi-
nutes. See owner's manual appears in the Info-
tainment system display. The side marker lights
will switch off after approximately 30 minutes or
when you lock the vehicle.
If the Start/Stop system has not turned off the
engine or if you have switched the Start/Stop sys-
tem off manually, the ignition will not be auto-
matically switched off and the engine will contin-
uetorun>A.

ZA WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
G) Tips
If you select the “D” or “N” selector lever posi-
tion after shifting into reverse, the vehicle
must be driven faster than 6 mph (10 km/h)
in order for the engine to switch off again.

Electromechanical
parking brake
The ©) switch is located under the selector lever
in the center console.
Your vehicle is equipped with an electromechani-
cal parking brake. The parking brake is designed
to prevent the vehicle from rolling unintentional-
ly and replaces the hand brake.
Setting and releasing the parking brake
manually

tion is switched on and press the ©) switch at
the same time. The LED in the button and the
indicator light in the display turn off.
Releasing the parking brake automatically
Requirement: the driver's door must be closed.
> To start driving and release the parking brake
automatically, press the accelerator pedal as
usual.
In addition to releasing the parking brake auto-
matically, other convenience and safety functions
are available when you start driving > page 80,
Starting to drive.
Emergency braking function
You can use the emergency braking function in an
emergency situation, or if the standard brakes
are malfunctioning or the pedal is obstructed.
> 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 hydraulic brake system will brake all
four wheels. The braking effect is similar to heavy
braking > A\.
To reduce the risk of activating the emergency
braking by mistake, a warning tone (buzzer)
sounds when the ©) switch is pulled. Emergency
braking stops as soon as the ©) switch is released
or the accelerator pedal is pressed.

Driving

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 > /A\.
> Turn the steering wheel when parking on in-
clines so that the wheels will roll into the curb
if the vehicle starts moving.

Z\ WARNING
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is
pressed. To reduce the risk of an accident,
do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— Emergency braking should only be used in
an emergency, when the when the standard
brake pedal is malfunctioning or 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 once it is released. In this
case, park the vehicle on level ground and
secure it by placing the selector lever in the
P position. See an authorized Audi dealer or
authorized Audi Service Facility for assis-
tance.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. This
applies particularly when children remain in
the vehicle. Otherwise children could start
the engine, release the parking brake or op-
erate electrical equipment such as power
windows, which increases the risk of an acci-
dent.
— 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.

80
@) Note
Do not leave your vehicle unattended while
the engine is running, because this increases
the risk of an accident.
@) Tips
— Noises when the parking brake is set and re-
leased are normal and are not a cause for
concern.
— The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are
normal.
Starting to drive
Various convenience and safety functions may be
available when the vehicle begins driving, de-
pending on vehicle equipment.
Starting on hills with the parking brake set
Requirement: the driver's door must be closed.
> To start driving comfortably 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
If you take your foot off of the brake pedal when
driving on hills, the braking force will be held for
several seconds. At that time, you can start driv-
ing without the vehicle rolling backward.
Requirement: the driver's door must be closed,
the engine must be on, and the vehicle must be
traveling uphill.
> To activate hill hold assist, press and hold the
brake pedal for several seconds while the vehi-
cle is stationary.

ZA\ WARNING
—To reduce the risk of an accident, always
make sure the vehicle is situated safely
while stationary.
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is >

pressed. To reduce the risk of an accident,
do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— If the power supply fails, you cannot set the
parking brake once it is released, or release
it if it is set. In this case, park the vehicle on
level ground and secure it by engaging the
"P” gear. Contact an authorized Audi dealer
or authorized Audi Service Facility for assis-
tance.

ZA WARNING
— If you do not begin driving immediately after
releasing the brake pedal, your vehicle may
begin to roll backward. Press the brake ped-
al or set the parking brake immediately.
— The hill hold assist cannot hold the vehicle
on inclines in every scenario (for example,

on slippery or icy ground).

Sporty driving
Applies to: RS models
When driving in a sporty style, the wear on all ve-
hicle components is greatly increased, especially
on the engine, transmission, tires, brakes, and
suspension. This can result in increased wear. Al-
so
note the following points:
— Make sure the vehicle is in good condition.
Make sure to check the brake pads, tire tread,
and tire pressure (when tires are warm).
— Beforehand, warm up the engine by driving no
higher than two-thirds of the maximum permit-
ted engine RPM. The engine oil must be
brought to a minimum temperature of 158 °F
(60 °C).
— Before stopping the vehicle, allow the engine
and brakes to cool back down to a regular oper-
ating temperature by driving normally.
If necessary, use the following functions:
— Dynamic Audi drive select mode* > page 96
— Launch Control > page 86
— Limit ESC > page 105
@) Tips
Wear caused by load does not constitute a ve-
hicle fault as defined by the terms of the war-
ranty.
Automatic transmission
Introduction
Your vehicle is equipped with an electronically-
controlled DSG transmission called S tronic. Two
independent clutches transfer the power be-
tween the engine and transmission. It allows the
vehicle to accelerate without a noticeable inter-
ruption in traction.
The transmission shifts up or down automatically
depending on which drive program is selected.
When a moderate driving style is used, the
transmission selects the most economical driving
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a sporty driv-
ing style characterized by quick accelerator pedal
movements, heavy acceleration, frequent
changes in speed, and traveling at the maximum
speed.
If desired, the driver can also select the gears
manually (tiptronic mode) > page 85.

You can only shift into Park when the vehicle is
stationary > A.
To shift in and out of the P selector lever position,
press the interlock button in the selector lever
while pressing the brake pedal.
R - Reverse
Only shift into reverse gear when the vehicle is
stationary and the engine is running at idle
speed >A.
To select the R selector lever position, press the
interlock button while pressing the brake pedal.
The back-up lights switch on in the R position if
the ignition is switched on.
N - Neutral (idle)
The transmission is in idle in this position.
D/S - Normal position for driving forward
In the D/S selector lever position, the transmis-
sion can be operated either in the normal D mode
or in the S sport mode. To select the S sport
mode, pull the selector lever back briefly. Pulling
the lever back again will select the normal D
mode. The selected driving mode is shown in the
Infotainment display.
In the normal mode "D", the transmission auto-
matically selects the correct gear. It depends on
engine load, vehicle speed and driving style.
Select the sport mode "S" for sporty driving. The
vehicle makes full use of the engine's power.
Shifting may become noticeable when accelerat-
ing.
To move from selector lever position "N" to "D",
you must press the brake pedal and the vehicle
must be traveling less than 1 mph (2 km/h) or be
stationary > A.


— Never select "R" or "P" while driving, be-
cause this increases the risk of an accident.
— Power is still transmitted to the wheels
when the engine is running 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, this increases the risk
of an accident.
— Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged. Otherwise the vehicle will start to
move immediately, even if the parking brake
is set. This could result in a crash.
— Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
— Never leave your vehicle with the engine
running while in gear. If you must leave your
vehicle when the engine is running, set the
parking brake and move the selector lever to
the "P" position.
— To decrease the risk of an accident, the se-
lector lever must be in the P position and
the parking brake must be set before open-
ing the hood and working ona running en-
gine. Always read and follow the applicable
warnings > page 200, General information.


Z\ WARNING
Read and follow all WARNINGS.
— Before starting to drive, check if the desired
selector lever position is displayed next to
the selector lever.
— The vehicle can roll even if the ignition is

switched off.

82
@) Note
Never let the vehicle roll downhill with engine
off and the selector lever in the "N" position,
because this could damage the automatic
transmission and catalytic converter.
(i) Tips
— Drive select: sporty shifting characteristics
can be selected using the Dynamic driving
mode. The Infotainment display shows “S”
as the selector lever position instead of “D”.
— If you accidentally select "N" while driving,
take your foot off the accelerator pedal im-
mediately and wait for the engine to slow
down to idle before selecting "D" or "S".
— If there is a power failure, the selector lever
will not move out of the "P" position. The >

The automatic shift lock only functions when the
vehicle is stationary or at speeds below 1 mph
(2 km/h). At higher speeds, the lock is automati-
cally deactivated in the "N" position.
The selector lever is not locked when shifting
quickly through "N", for example from "R" to "D".
This makes it possible to free the vehicle when it
is stuck by “rocking” it. The selector lever lock en-
gages if the lever stays in the "N" position longer
than approximately two seconds when the brake
pedal is not pressed.

The interlock button in the selector lever handle
prevents you from moving the selector lever in-
advertently while in some selector lever posi-
tions. The positions that require the interlock
button to be pressed are marked in color in the il-
lustration > fig. 88.

Z\ WARNING
Read and follow all WARNINGS. > A\ in Selec-
tor lever positions on page 82.
G) Tips
— If the selector lever does not engage, there
is a malfunction. The engine is disabled to
prevent the vehicle from driving off uninten-
tionally. To allow the selector lever to en-
gage again, proceed as follows:
— Briefly press the brake pedal.
— If the vehicle does not move forward or in
reverse even though a drive position is se-
lected, proceed as follows:
— If the vehicle does not move in the desired
direction, the system may not have engaged
the drive position correctly. Press the brake
pedal
and select the drive position again.
— If the vehicle still does not move in the de-
sired direction, there is a system malfunc-
tion. See an authorized Audi dealer or au-
thorized Audi Service Facility for assistance

Stopping/parking
If the selector lever is not in the "P" position
when you open the driver’s door, the vehicle
could roll.
In vehicles with a convenience key*, the message
Shift to P, otherwise vehicle can roll away.
Doors do not lock if gearshift is not in P ap-
pears. A warning tone will also sound.
> Press and hold the brake pedal > A\.
> Set the parking brake.
> Select the "P" selector lever position.
Under certain circumstances, such as driving in
the mountains, it may be useful to switch tempo-
84
rarily to tiptronic mode in order to manually ad-
just the gears to the driving conditions
=> page 85.
On
hills, activate the parking brake first and then
shift into the "P" selector lever position. This pre-
vents too much stress from being placed on the
locking mechanism.

ZA WARNING
— The vehicle can roll even when the engine is
switched off.
— Unintended vehicle movement can lead to
serious injuries.
— Never leave your vehicle with the engine
running while in gear. If you must leave your
vehicle when the engine is running, set the
parking brake and move the selector lever to
the P position.
— Power is still transferred to the wheels when
the engine is running at idle. To prevent the
vehicle from “creeping”, you must keep your
foot on the brake when the engine is run-
ning and the selector lever is in the "D", "S"
or
"R" position or “tiptronic” mode is select-
ed.
— Do not inadvertently press the accelerator
pedal when the vehicle is stationary. Other-
wise the vehicle will start to move immedi-
ately, even if the parking brake is set. This
could result in a crash.
— Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
— Never engage the R or P selector level posi-
tions while driving. It could cause a crash.
— Before driving down a steep slope, reduce
your speed and shift into a lower gear with
“tiptronic”.
— Do not ride the brakes or press the brake
pedal
too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and can substantially re-
duce braking performance, increase braking
distance, or cause complete failure of the
brake system.
