The steering is locked if the key is not in the ignition and the driver
door has been opened. The steering lock acts as a theft deterrent.
WARNING
Never run the engine in confined spaces. The exhaust gases are
toxic.•
Never switch off the engine until the vehicle is stationary.
•
The brake servo and the power steering system work only
when the engine is running. You need more strength to steer and
brake the vehicle when the engine is switched off. This would
mean a greater risk of accidents and serious injury, because you
cannot steer and brake in the normal manner.Caution
•
Avoid high engine speeds, full throttle and extreme load condi-
tions until the engine has reached its normal operating tempera-
ture, otherwise this can damage the engine.
•
The engine cannot be started by push-starting or towing.
•
If the engine has been working hard for a long time, there is a risk
of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason,
you should leave the engine idling for about 2 minutes before
switching it off.Note
If you open the driver's door while the ignition is switched on, a
warning buzzer will sound, and the message Ignition is on will
appear in the display. In this case, please switch off the ignition.
Switching off the engine with the Start/Stop button–Stop the vehicle.
– Automatic gearbox: Move the selector lever to position P
or N.
–Press the Start/Stop button ⇒page 118, fig. 131.Emergency Off function
Should it be necessary in an emergency, the engine can be switched
off when the selector lever is in position R, D or S. To switch off the
engine (max. speed 10 km/h) press and hold the Start/Stop button
and keep your foot on the brake.

Electro-mechanical parking brakeOperation
The electro-mechanical parking brake replaces the hand-
brake.– Pull switch ⇒fig. 132 to apply the parking brake. The
indicator lamp in the switch will light up.
– Depress the brake or accelerator pedal and press the
switch at the same time to release the parking brake. The
indicator lamp in the switch will go out.Your vehicle is equipped with an electro-mechanical parking brake.
The parking brake replaces the conventional handbrake, and is
mainly intended to prevent the vehicle from rolling away acciden-
tally.
However, the electro-mechanical parking brake also offers a number
of convenience and safety features in addition to the functions of a
normal handbrake.When driving away
•
The parking brake auto release function releases the parking
brake automatically when you wish to start moving ⇒page 122,
“Driving away from a standstill”.
•
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The
braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Emergency braking function
An emergency braking function enables you to stop the vehicle even
if the conventional foot brake should fail to work ⇒page 123,
“Emergency braking function”.
Warning and indicator lamps
•
The warning lamps
 in the instrument cluster and in the switch
light up when the parking brake is applied with the ignition
switched on.

up for approximately 20 seconds when the parking brake is applied
with the ignition switched off.
WARNING
Never press the accelerator pedal or release the clutch inadvert-
ently if a gear is engaged or if the selector lever is not in position
P or N (on automatic vehicles) while the vehicle is stationary with
the engine running. The vehicle could otherwise start moving
immediately and possibly cause an accident.
Caution

Technical data lights or in stop-and-go traffic. When the Audi hold assist function
is on, you don't have to keep your foot on the brake to prevent the
vehicle from accidentally rolling away. Once it detects that the
vehicle is stopped, Audi hold assist keeps the vehicle stationary. The
green symbol
 in the instrument cluster indicates that the func-
tion is activated. You can now take your foot off the brake pedal.
As soon as you drive off in the normal way, the parking brake will
automatically be released and the vehicle will start moving.
If the conditions for Audi hold assist change and the function is
switched off as a result, the parking brake will be applied automati-
cally to ensure that the vehicle is parked safely. The diode in the
button will go out when the Audi hold assist function is switched
off.
WARNING
The intelligent technology in Audi hold assist cannot defy the laws
of physics. Do not let the extra convenience provided by Audi hold
assist tempt you into taking a safety risk.•
Audi hold assist cannot keep the vehicle stationary in all condi-
tions on a gradient (e.g. if the road is slippery or icy).
•
Audi hold assist must be switched on again each time the
engine is started – Risk of accident!
•
Never get out of the vehicle when the engine is running and
Audi hold assist is switched on – Risk of accident!
•
Always ensure that the vehicle is stopped properly and safely
to avoid injury to yourself and others.Caution
Switch off the Audi hold assist function before driving the vehicle
into a car wash.
Note
•
Audi hold assist can be switched on only when the driver's door
is closed, the driver's seat belt is buckled and the engine is running.
•
Audi hold assist prevents automatic vehicles from creeping
forwards when the brake pedal is released with the car in gear.
•
When the vehicle has been stationary for an extended period,
Audi hold assist will automatically apply the parking brake. In this
case, the green symbol
 in the instrument cluster display will
change to red
.

Note•
You can select the sport program for gear changes on vehicles
with an automatic gearbox* by activating the DYNAMIC mode. There
is no S position on the selector lever.
•
You may hear a noise on vehicles with dynamic steering* when
you start or stop the engine. This is no cause for concern.
Applies to vehicles: with Audi drive selectSelecting the driving mode
You can choose between COMFORT, AUTO, DYNAMIC and
INDIVIDUAL*.
The control is next to the selector gate ⇒fig. 174 on vehi-
cles with sound system, or in the centre console ⇒fig. 175
on vehicles with MMI*.
– Switch on the ignition.
– Press the left or right arrow button until the desired
mode lights up in red.You can change the driving mode while the vehicle is stationary or
moving. If traffic conditions permit, take your foot off the acceler-
ator briefly after you change the mode so that the new mode is also
activated for the engine.
COMFORT
The COMFORT mode alters the vehicle set-up for a more comfort-
able ride. The response of the engine and automatic gearbox* to
accelerator pedal movements is balanced. The steering is light and
indirect* and the suspension control* is set to soft. This setting is
suitable for driving long distances on motorways for example.
AUTO
The overall impression in AUTO mode is of a comfortable but
dynamic ride. This setting is suitable for everyday use.
DYNAMIC
DYNAMIC gives the vehicle a tighter set-up. The engine reacts spon-
taneously to accelerator pedal movements and the steering is
dynamic and direct*. The suspension control* is stiffer and the
automatic gearbox* changes gear at higher engine speeds. This
setting is ideal for performance driving.
INDIVIDUAL*
You can configure this mode on the MMI according to your personal
preferences.

– Press and hold the interlock button, move the selector
lever to P and release the interlock button.The engine c an only be started when the selector lever is at P or N.
On level ground it is sufficient to move the selector lever to P. On a
gradient the parking brake should be applied first and the selector
lever should be moved to P. This reduces the load on the locking
mechanism and makes it easier to move the selector lever out of
position P.
Vehicles with multitronic® gearbox: Your vehicle is equipped with
the hill hold assist function which makes it easier to drive away on
a slope. The system is activated when you press and hold the brake
pedal for a few seconds. When you release the brake pedal the
braking force will be maintained for a moment in order to prevent
the vehicle rolling back when you drive away.
WARNING
•
Do not press the accelerator while selecting a gear with the
vehicle stationary and the engine running, as this could cause an
accident.
•
Please note that some power will still be transmitted when you
stop temporarily with the selector lever in position D, S or R. For this reason, to avoid risking an accident, apply the footbrake firmly
when stopping to prevent the vehicle rolling away.

– Press the control button for Mode ⇒fig. 194 on the
MMI control console. Parking mode 2 is displayed.
– Reverse and align your vehicle in such a way that the blue
area marking borders onto the vehicle behind or onto
the parking space line marking. The blue marking is an
extension of the vehicle outline and reaches about five
metres to the rear of the vehicle. The long side of the blue
marking should border onto the kerb. The complete blue
area marking must fit into the parking space.
– When the vehicle is stationary turn the steering wheel to
the left as far as it will go.
– Reverse into the parking space.
– Stop the vehicle as soon as the blue curve touches the
kerb ⇒page 175, fig. 195.
– When the vehicle is stationary turn the steering wheel to
the right as far as it will go.
– Continue to reverse into the parking space until the
vehicle is standing parallel to the kerb. indicates the
rear bumper. You should stop reversing, at the latest,
when the red orientation line is bordering on an
object ⇒! Keep a close watch on the front of your
vehicle ⇒.Parking next to obstacles
If an obstacle (such as a wall) is located next to the parking space,
the clearance at the side of the vehicle must be larger. Position the
long side of the blue marking so that there is sufficient clearance
from the kerb. The marking must not touch the kerb. You must also
start turning the steering wheel much earlier. The blue curve
⇒page 175, fig. 195 must not touch the kerb - make sure there is
sufficient clearance from the kerb.
WARNING
•
The reversing camera does not show the complete area behind
the vehicle. It is particularly important to ensure that there are no
small children or animals near the vehicle, as the reversing camera
may not always be able to detect them (accident risk).
•
Please note that objects which are not touching the ground
may appear to be further away than they actually are (e.g. the
bumper of a parked vehicle, a towing bracket or the rear end of a
truck). In this case you should not use the orientation lines as a
guide when parking the car - accident risk!Caution
The MMI display shows the path of the rear end of the vehicle if you
were to reverse using the current steering angle. NB: The front end
of the vehicle swings out further than the rear. Please make sure you
keep a sufficient distance between the vehicle and any obstacles to
make sure that the exterior mirror or edge of the vehicle do not
collide with the obstacle (accident risk).
Note
The orientation lines and markings appear on the left or right side,
depending on which turn signals are on.
