If you would like to switch the ignition on without
starting the engine, follow these steps:

> Press the [START ENGINE STOP} button without
pressing the brake pedal.


Starting the engine
> Automatic transmission: press the brake pedal
and move the selector lever into the “P” or “N”
position > /\.
> Press the [START ENGINE STOP} button. The en-
gine will start.


Equipment that uses a lot of electricity is switch-
ed off temporarily when you start the engine.
If the engine does not start immediately, the
starting procedure stops automatically after a
short time. If this is the case, repeat the starting
procedure after approximately 30 seconds.

ZA\ WARNING
—To reduce the risk of asphyxiation, never al-
low the engine to run in confined spaces.
— Never turn off the engine before the vehicle
has come to a complete stop.
— The brake booster and power steering only
work when the engine is running. If the en-
gine is off, you have to use more force when
steering or braking. The fact that you cannot
steer and brake as usual may increase the
risk of accidents and serious injuries.
() Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.

@) For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re-
duces unnecessary emissions.
(i) Tips
— Some noise after starting the engine is nor-
mal and is no cause for concern.
— If you leave the vehicle with the ignition
switched on, the ignition will switch off af-
ter a certain amount of time. Make sure
that electrical equipment such as the exteri-
or lights are switched off.

Driving

Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP] button.


Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To stop the engine, press the
START ENGINE STOP] button twice in a row or


press and hold it one time.

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 may need to use more
force when braking or steering. Because you
cannot brake and steer as you usually would,
this could lead to accidents and serious inju-
ries.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. If you
do not do this, the engine could be started
and electrical equipment such as the power
windows could be activated. This can lead to
serious injuries.
— For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@) Note
If the engine has been under heavy load for an
extended period of time, heat builds up in the
engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
@) Tips
For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again auto-
matically or it may continue to run, even if the
ignition is switched off.

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.

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.

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.
