Driving
Starting the vehicle
(eta
Applies to: vehicles with convenience key



Fig. 100 Center console: starting the engine
Requirement: the key must be in the vehicle.
Starting the engine
> Press and hold the brake pedal.
> Press the [START ENGINE STOP] button. The
engine 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 start-
ing procedure stops automatically after a short
time. If this is the case, repeat the starting pro-
cedure after approximately 30 seconds.
Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP] button. The
engine will switch off.



Applies to: vehicles with steering lock: The steer-
ing is locked when you turn off the engine and
open the driver's door. The steering lock helps
prevent vehicle theft. “P” must be engaged on
vehicles with an automatic transmission.
Stopping the engine in an emergency
If necessary in an emergency, the engine can also
be stopped while driving using the emergency off
function*.

> Press the [START ENGINE STOP] button twice in
a row or press and hold it one time.

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

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

Switching the ignition off automatically
To prevent the vehicle battery from draining, the
ignition and possibly the exterior lighting may
switch off automatically.
Requirements:
— The Start/Stop system must have stopped the
engine.
— You must have left the vehicle for longer than
30 seconds.
— The ignition must be switched on.
Among other indicators, the system detects that
you have left the vehicle based on the following
factors:
— The driver's door has been opened.
— The driver's safety belt has been unbuckled.
— The brake pedal is not being pressed.
The ignition will also be switched off after 30 mi-
nutes or if you lock the vehicle from the outside.

Z\ 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. 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.
— Secure the vehicle against rolling before ex-
iting the vehicle > page 104.
CG) 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.


103

Driving

— 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 damag-
ing the engine. For this reason, let the en-
gine run at idle for approximately two mi-
nutes before shutting it off.
G) Tips
— Brief noises are normal when starting and
stopping the vehicle and are no cause for
concern.
— For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again au-
tomatically or it may continue to run, even if
the ignition is switched off.
— It may not be possible to start the vehicle in
extremely low temperatures.
— Power will be fully available once the engine
is at operating temperature.
Messages
= Engine start system: malfunction! Please
contact Service
There is a malfunction in the engine start system.
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.
B Remote control key: key not detected. Is the
key
still in the vehicle?
The vehicle key was removed from the vehicle
while the engine is running. If the vehicle key is
no longer in the vehicle, you cannot switch the ig-
nition on or start the engine once you stop it. You
also cannot lock the vehicle from the outside.
Remote control key: hold back of key
against the designated area. See owner's man-
ual
The battery in the vehicle key may be drained or
there may be a malfunction. To start the vehicle,
you must also hold the vehicle key against the lo-
cation shown P) > page 103, fig. 100.
If the malfunction remains, drive immediately to
an authorized Audi dealer or authorized Audi
104
Service Facility to have the malfunction correct-
ed.
When driving
Starting to drive, stopping, and parking
Starting from a stop
> Press and hold the brake pedal.
> Start the engine.
> Select a gear.
> Release the parking brake.
> Release the brake pedal. The vehicle may roll.
> Press the accelerator pedal to accelerate.
Securing the vehicle against rolling
Secure your vehicle to prevent it from rolling be-
fore exiting the vehicle.
> Set the parking brake.
> Select the “P” selector lever position.
> If parking on a steep road, turn the steering
wheel so that your vehicle will roll against the
curb in case it should start to move.
If one of these measures is not possible, for ex-
ample because there is no vehicle power, you
must secure your vehicle against rolling using ad-
ditional measures.
> Only park the vehicle on a level surface.
> Use suitable objects to block the front and rear
wheels.
Set the parking brake before selecting the “P” se-
lector lever position. This prevents too much
stress from being placed on the locking mecha-
nism when parking on a steep surface.

ZA WARNING
— Always set the parking brake when leaving
your vehicle, even if for a short period of
time. If the parking brake is not set, the ve-
hicle could roll away, increasing the risk of
an accident.
— Do not leave your vehicle unattended while
the engine is running, because this increases
the risk of an accident.
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is

pressed. To reduce the risk of an accident, >
