ZA\ WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
@) 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.
G) 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 exterior
lights are switched off.
Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP] button.



)_ This function is not available in all countries.
Steering lock!)
The steering is locked when you switch off the en-
gine and open the driver's door. The locked steer-
ing helps prevent vehicle theft.

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 the vehicle is stopped, such as at
a traffic light. The ignition remains switched on
during this stop phase. The engine will restart
automatically when needed.

4S1012721BA
Driving

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 engine compartment lid 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 64.

from starting unintentionally when shifting
through R.
@) Tips
— 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.
— The ignition will turn off if you press the

Driving

— 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
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.

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/manually releasing the parking
brake
> Pull the @) switch to set the parking brake. The
LED in the switch turns on. The Zw (USA mod-
els)/[@) (Canada models) indicator light also
turns on in the instrument cluster display.

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 66,
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.
Parking
> Press the brake pedal to stop the vehicle.
> Pull the ©) switch to set the parking brake.
> Select the "P" selector lever position.
> Turn the engine off > /\.
> Turn the steering wheel when parking on in-
clines so that the wheels will roll into the curb
if the vehicle starts moving.

ZA WARNING
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Otherwise, the vehicle will start to move im-
mediately and this could result in an acci-
dent.
— 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) can-
not overcome the laws of physics. In corners
and when road or weather conditions are
bad, a full brake application can cause the

65

Driving


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.

@) Note
Do not leave your vehicle unattended while
the engine is running, because this increases
the risk of an accident.
@) 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
you press the accelerator pedal, the parking
brake releases automatically and the vehicle
starts to move > page 66.
G@) Tips
— Occasional noises when the parking brake is
set and released 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.
66
— 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 > A\. See an authorized
Audi dealer or authorized Audi Service Fa-
cility for assistance.
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
Hill hold assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the engine must be running.
> To activate hill hold assist, press and hold the
brake pedal for several seconds. The vehicle
must be facing uphill.
After releasing the brake pedal, the braking pow-
er is maintained briefly > A\ to prevent the vehi-
cle from rolling back when starting. This allows
you to begin driving more easily.

Z\ WARNING
Applies to: vehicles with hill hold assist
— If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your vehicle 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 physical laws. The increased comfort
offered by hill hold assist should not cause
you to take safety risks. >

4S1012721BA
Driving


— The vehicle can roll even if the ignition is
switched off.
— 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" and "N") when
the engine is running.
— Before opening the engine compartment lid,
select the "P" selector lever position and set
the parking brake. This reduces the risk of
an accident. Always read and follow the ap-
plicable warnings > page 229, General in-

formation.
@ Tips
If you accidentally select "N" while driving,
take your foot off the accelerator pedal and
wait for the engine to slow down to idle be-
fore selecting "D" or "S".

mountains, it may be helpful to switch to manual
mode temporarily to adapt to the driving condi-
tions manually > page 71.
On hills, activate the parking brake first and then
shift into the "P" position. This prevents too
much stress from being placed on the locking
mechanism.

ZA WARNING
— Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running. This could result in a crash.
— To reduce the risk of an accident, never se-
lect the "R" or "P" positions while driving.
— 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.

@) Note
— When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac-
celerator pedal while a driving gear is se-
lected. This can cause the automatic trans-
mission to overheat and can damage it. Set
