WARNING
- Never press the accelerator pedal or release
the clutch inadvertently 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 will otherwise start moving immedi­
ately and could cause an accident.
- You should only use the emergency braking
function in a real emergency, for example if
the brake system were to fail or if the brake
pedal were to be obstructed. If you use the
emergency braking function by activating
the parking brake switch, this has the same
effect as heavy braking. Please remember
that the ESC (and the integrated ABS, EDL
and traction control functions) is still sub­
ject to certain physical limits. In a corner or
in bad road or weather conditions an emer­
gency stop can cause the vehicle to skid or
lose steering control.
- It is not possible to apply the parking brake
if the electrical power supply fails. In this
case, park the vehicle on a level surface and
select 1st gear (manual gearbox) or move
the selector lever to position P (automatic
gearbox) to prevent it from rolling. Obtain
professional assistance.
- Always take the key with you when leaving
your vehicle -even if you only intend to be
gone for a short time. This is especially im­
portant if children are left in the car. They
might otherwise be able to start the engine,
release the parking brake or use power-op­
erated equipment such as the electric win­
dows -this could lead to injuries.
- Do not leave anyone (especially children) in
the vehicle when it is locked. Locked doors
could delay assistance in an emergency, po­
tentially putting lives at risk.
Applies to: vehicles with automatic gearbox
You can apply the parking brake manually or
switch on the hold assist* when stopping at
traffic lights, etc. You do not then have to
hold the car with the brake pedal, as the Driving
brakes will stop it creeping forward while a
gear is engaged in the automatic transmis­
sion. When you drive off in the normal way,
the parking brake will be released automati­
cally and your vehicle will start moving
¢page 75.
(CD) Note
- Any slight noise which may be heard when
the parking brake is applied or released is
quite normal and no cause for concern.
- The parking brake runs an automatic test
cycle at regular intervals when the vehicle is
parked. This may cause a slight noise, which
is normal.
- If the electrical power supply fails, it is not
possible to release the parking brake (if it
was applied) or to apply the parking brake
(if it was released) ¢ &,. Obtain professional
assistance.
Moving off
Various features and safety functions are availa­
ble for driving off, depending on the equipment
in your vehicle.
Hill starting with the parking brake applied
Important: The driver's door must be closed.
� To drive off more easily on a slope, apply the
parking brake and drive off just as you usually
would. The parking brake will be released auto­
matically, but not until there is enough power
at the wheels to make the vehicle move in the
desired direction.
Hill starting with the hill hold assist
The hill hold assist function makes it easier to
drive away on a slope.
Important: The driver's door must be closed and
the engine must be running.
� To activate the hill hold assist, press and hold
the brake pedal for several seconds. The vehicle
must be on a slope and facing uphill.
When you release the brake pedal the braking
force will be maintained for a moment ¢.&. in

order to hold the vehicle and make it easier for
you to drive away.
Driving off with the hold assist
Applies to: vehicles with hold assist
The hold assist helps the driver if the vehicle is
stationary for a long period or very often, for in­
stance at traffic lights, on steep gradients or in
stop-and-go traffic.
Important: The driver's door must be closed and
the engine must be running.
.,. To switch the hold assist on/off, press the but­
ton(@) @¢page 74, Fig. 78, ¢A .The LED in
the button will light up or go out.
.,. Once it detects that the vehicle has stopped,
the hold assist keeps the vehicle stationary.
You can now take your foot off the brake pedal.
.,. Drive
off in the normal way: the brake will be
released automatically and the vehicle will
start moving.
In certain situations, the hold assist transfers the
job of holding the vehicle to the parking brake.
As soon as the parking brake is holding the vehi­
cle still, the warning lamp. appears in the in­
strument cluster. In addition, the LED in the C®)
button will light up.
Driver messages in the instrument cluster
display
[iJ Hold assist: unavailable
If this message appears, the system require­
ments have not been met.
A WARNING
Applies to: vehicles with hill hold assist
If you do not drive away immediately after re­
leasing the brake pedal, or if the engine
stalls, the vehicle may start to roll back. You
should therefore immediately press the brake
pedal or apply the parking brake.
A WARNING
The intelligent technology in the hold assist*
and hill hold assist functions cannot defy the
laws of physics. Do not let the extra conven­
ience afforded by the hold assist* and hill
76 hold
assist functions tempt you into taking
any risks when driving -this can cause acci­
dents.
- The hold assist* and hill hold assist func­
tions cannot keep the vehicle stationary in
all conditions on a gradient (e.g. if the road
is slippery or icy).
- Always ensure that the vehicle is stopped
properly and safely -risk of accident!
CD CAUTION
Switch off the hold assist* function before
driving the vehicle into a car wash.
� Note
Applies to: vehicles with automatic gearbox
When the hold assist* function is switched
on, it stops the vehicle from creeping for­
wards when you take your foot off the brake
pedal.
Automatic gearbox
Introduction
Applies to: vehicles with automatic gearbox
The vehicle is equipped with an electronically
controlled dual-clutch gearbox (S tronic). Torque
between the engine and the gearbox is transmit­
ted via two independent clutches. They enable
smooth, uninterrupted acceleration of the vehi­
cle.
The gearbox shifts up or down automatically and
continuously adapts the timing of the gear
changes to your driving style.
When you drive at moderate speeds the gearbox
will select the most economical shift pro­
gramme. It will then change up early and delay
the downshifts to give better fuel economy.
If you drive at higher speeds with heavy accelera­
tion, if you open the throttle quickly, or if you use
the kick-down or the car's maximum speed, the
gearbox will automatically select the more "spor­
ty" shift programmes.
If desired, you can also select the gears manually
(tiptronic mode).

Applies to: vehicles with automatic gearbox
Fig. 79 Instrument cluster: Selector lever positions
The current selector lever position and the cur­
rent gear are shown in the infotainment display.
P - Parking lock
The parking lock must only be engaged when the
vehicle is stationary ¢ A.
The interlock button (the button in the selector
lever handle) must be pressed in and the brake
pedal must be depressed before moving these­
lector lever either in or out of position P.
R - Reverse gear
Reverse gear should only be engaged when the
vehicle is stationary and the engine is idling ¢
A.
To move the selector lever to position R, press in
the interlock button and at the same time press
the brake pedal. The reversing light comes on
when the selector Lever is in the R position with
the ignition on.
N - Neutral
In this position, the gearbox is in neutral.
DIS -Drive/Sport (standard position for
driving forwards}
In selector Lever position D/S, the gearbox can be
operated in either the standard drive mode (D) or
in sport mode (5). To select sport mode (5), brief­
ly pull the selector lever back. The gearbox will
switch back to drive mode (D) if you pull these­
lector lever again. The selected driving mode is
shown on the infotainment display.
In the standard drive mode (D), the gearbox au­
tomatically selects the best gear ratio. This de- Driving
pends on the engine load, the road speed and the
driving style.
Select sport mode (S) if you wish to take full ad­
vantage of the car's performance. This setting
makes use of the engine's maximum power out­
put. When accelerating the gear shifts may be
noticeable.
Press the brake pedal when moving the selector
Lever from N to D/S if the vehicle is stationary or
at speeds below 2 km/h ¢ A.
E - Efficiency*
In efficiency mode¢ page 100, Audi drive select
(vehicle set-up functions), the gearbox selects
the next gear at Lower engine speeds. Earlier up­
shifts give improved fuel economy because the
full power reserves of the engine are not used.
In this mode, Eis shown on the display instead of
D ¢Fig. 79.
.&_ WARNING
- The car can roll away even if the ignition is
switched off.
- Never move the selector lever to R or P
when driving, as this could cause an acci­
dent.
- In all selector Lever positions except P the
vehicle must always be held with the foot
brake when the engine is running. This is be­
cause an automatic gearbox still transmits
power even at idling speed, and the vehicle
tends to "creep" -risk of accident!
- The accelerator pedal must on no account
be pressed inadvertently when a gear is en­
gaged with the vehicle stationary. The vehi­
cle could otherwise start moving immedi­
ately (in some cases even if the parking
brake is engaged) and possibly cause an ac­
cident.
- Do not press the accelerator while selecting
a gear with the vehicle stationary and the
engine running, as this could cause an acci­
dent.
- The driver should never get out of the vehi­
cle when the engine is running and a gear is
engaged. If you have to leave your vehicle ..,.

Selector lever lock
Applies to: vehicles with automatic gearbox
The selector Lever Lock prevents gears from being
engaged inadvertently, so that the vehicle is not
set in motion unintentionally.
Fig. 80 Selector lever lock
The selector lever lock is released as follows:
• Switch on the ignition.
78 •
Press the brake pedal and at the same time
press in the interlock button.
Automatic selector lever lock
The selector lever is locked in the P and N posi­
tions when the ignition is on. To move the selec­
tor lever out of these positions the driver must
press the brake pedal. To move out of position P,
the interlock button must also be pressed. The
following message appears in the display as a re­
minder for the driver when the selector lever is in
position P or N:
To select a gear please press brake pedal and in­
terlock button on gear selector lever
The selector lever lock only works if the vehicle is
stationary or driving at speeds up to 2 km/h. At
higher speeds the selector lever lock in the N po­
sition is disengaged automatically.
The selector lever lock is not engaged if the se­
lector lever is moved quickly through position N
(e.g. when shifting from R to D). This makes it
possible, for instance, to "rock" the vehicle back­
wards and forwards if it is stuck in snow or mud.
The selector lever lock engages automatically if
the brake pedal is not depressed and the lever is
in position N for more than about two seconds.
Interlock button
The interlock button on the selector lever handle
prevents the driver from inadvertently engaging
particular gears. The illustration shows the selec­
tor lever positions in which the button has to be
pressed, highlighted in colour¢ Fig. 80.
{(D) Note
- If the selector lever does not lock automati­
cally, a malfunction has occurred. In this
case, the power transmission is interrupted
to prevent the vehicle from moving uninten­
tionally. Proceed as follows to engage the
selector lever lock again:
- Press the brake pedal briefly.
- If the vehicle does not move forwards or
backwards even though a gear is selected,
proceed as follows:

General notes on driving an automatic
Applies to: vehicles with automatic gearbox
The gearbox changes the forward gears up and
down automatically.
Fig. 81 Detail of the centre console: Selector lever with in­
terlock button
Starting the engine
.,. The selector lever must be in position P or N. In
the case of low outside temperatures (be-
low -10 °(), the engine can only be started
when the selector lever is in position P.
Driving away from a standstill
.,. Press and hold the brake pedal.
.,. Press
and hold the interlock button (the button
in the selector lever handle), set the selector
lever to the desired position (e.g. D) ¢ page 77
and release the interlock button.
.,. Wait
for the gearbox to engage the gear (a
slight movement can be felt).
.,. Release the brake and press the accelerator
¢ .&, .
There are several convenient functions to help
you drive away on gradients ¢page 75.
Stopping briefly
.,. Press the brake pedal to hold the vehicle when
stationary (for instance at traffic lights). Driving
.,. Do not press the accelerator .
.,. To prevent the vehicle from rolling away, apply
the parking brake before moving off on steep
gradients ¢.&. and ¢(D.
.,. As soon as you accelerate as normal with your
seat belt fastened, the parking brake will auto­
matically be released and the vehicle will start
moving.
Stopping/parking the car
If you open the driver's door while the selector
lever is not in position P, the vehicle can roll
away. The message Shift to P, otherwise vehicle
can roll away. Doors do not lock if lever is not in
P appears on vehicles with convenience key*. A
buzzer will also sound .
.,. Press and hold the brake pedal¢ .&, .
.,. Apply the parking brake .
.,. Move
the selector lever to P.
In some situations (such as when driving on
mountain roads) it can be advantageous to
switch temporarily to the manual shift pro­
gramme so that the gear ratios can be selected
manually to suit the driving conditions
¢page 81.
On level ground it is sufficient to move the selec­
tor lever to P. On a gradient the parking brake
should be applied first and the selector lever
should be moved to P ¢ page 74. This reduces
the load on the locking mechanism and makes it
easier to move the selector lever out of position
P
A WARNING
- The driver should never get out of the vehi­
cle when the engine is running and a gear is
engaged. If you have to leave your vehicle
while the engine is running, you must apply
the parking brake and engage the parking
lock P.
- If the engine is running and a gear is engag­
ed (D/S or R) or the vehicle is in "tiptronic"
mode, you will need to hold the car with the
footbrake. Otherwise, the car will "creep"
forwards as the power transmission is not

fully interrupted even when the engine is
idling.
- The accelerator pedal must on no account
be pressed inadvertently when the vehicle is
stationary. The vehicle could otherwise start
moving immediately (in some cases even if
the parking brake is engaged) and possibly
cause an accident.
- Do not press the accelerator while selecting
a gear with the vehicle stationary and the
engine running, as this could cause an acci­
dent.
- Never move the selector lever to R or P
when driving at normal speeds, as this could
cause an accident.
- Before you drive down a steep gradient, re­
duce the speed and use "tiptronic" to select
a low gear.
- Never allow the brake to drag when driving
downhill and do not use the brake pedal too
often or for long periods. Constant braking
will cause the brakes to overheat and will
considerably reduce the effectiveness of the
brakes. It will increase the braking distance
and could cause the brake system to fail.
- To avoid rolling back on gradients always
hold the vehicle with the footbrake or park­
ing brake if you have to stop.
- Never attempt to hold the vehicle with the
clutch when stopping on a gradient. The
clutch is disengaged automatically if it is
overloaded and becomes too hot -accident
risk! If the clutch is overloaded, the indica­
tor lamp 51 will light up and a message will
appear ¢page 83.
CD CAUTION
- When you have stopped on a gradient, do
not try to stop the vehicle rolling back by ac­
celerating when a gear is engaged. This
could cause the automatic gearbox to over­
heat and become damaged. Apply the park­
ing brake or press the brake pedal in order
to prevent the vehicle from rolling back.
- If you allow the car to roll with the selector
lever in position N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated.
80 -
In certain driving and traffic conditions, for
instance in stop-and-go traffic, if you have
to pull away frequently or if the vehicle
creeps forwards over a long distance, the
gearbox can overheat and become dam­
aged. If the indicator lamp 51 or the warn­
ing lamp . lights up, stop the vehicle at
the first opportunity and let the gearbox
cool down ¢page 83.
- If you allow the car to roll with the engine
switched off, the S tronic gearbox will be
damaged as it will not be lubricated
¢ page 2 78, Tow-starting I towing away.
ijJ) Note
For safety reasons the parking brake will only
release automatically if the driver's seat belt
is engaged in its buckle.
Downhill speed control
Applies to: vehicles with automatic gearbox
The downhill speed control function helps the
driver when driving down steep gradients.
Downhill speed control is activated on a downhill
gradient when the selector lever is in D/S and the
driver presses the brake pedal. The gearbox auto­
matically selects a suitable gear for the gradient.
The downhill speed control function attempts to
maintain the speed at which the vehicle was trav­
elling when the foot brake was applied (subject
to the laws of physics and technical limitations of
the power train). It may be necessary to adjust
the speed again using the foot brake. The down­
hill speed control can change down to 3rd gear
but no further, so it may be necessary to change
to tiptronic mode on very steep gradients. In this
case, change down manually to 2nd or 1st gear in
tiptronic mode to use the engine braking effect
and reduce the load on the brakes.
Downhill speed control is deactivated as soon as
the road levels out again or you press the acceler­
ator pedal.
On vehicles with cruise control system*
¢ page 86, downhill speed control is activated
when you set a cruising speed.
�

Downloaded from www.Manualslib.com manuals search engine I&
WARNING
The downhill speed control function cannot
defy the laws of physics and may therefore
not be able to maintain a constant speed in
certain circumstances. Always be prepared to
use the brakes!
Manual gear selection (tiptronic mode)
Applies to: vehicles with automatic gearbox
The tiptronic feature allows the driver to also
change gear manually.

� To shift down a gear, briefly pull the paddle lev­
er 0.
� Applies to TT RS: To select the lowest/highest
possible gear, hold the paddle lever 0 / 0 for
longer.
If you use the paddle levers when the selector
lever is in positions D/S, the gearbox will remain
in manual mode for a while. To switch back im­
mediately to automatic mode after changing
gears manually, pull the paddle lever 0
¢ Fig. 83 for approximately 1 second.
If you want to use the paddle levers permanent­
ly, push the selector lever from position D/S to
the right into the tiptronic selector gate.
The gearbox automatically shifts up or down into
the next gear before a critical engine speed is
reached.
Applies to RS model: When accelerating, the
gearbox does not automatically shift up into the
next gear shortly before the maximum engine
speed is reached. Remember to shift to the next
gear in good time.
The gearbox only allows manual gear changes if
the engine speed would remain within the per­
missible range.
Kick-down feature
Applies to: vehicles with automatic gearbox
The kick-down feature is designed to give maxi­
mum acceleration.
When the accelerator pedal is pressed right down
past the point of resistance at full throttle, the
gearbox will shift down to a lower gear, depend-
ing on road speed and engine speed, and the en­
gine power will be fully exploited. The upshift to

the next higher gear is delayed until the engine
reaches maximum rpm.
A WARNING
Please note that if the road surface is slippery
or wet, the kick-down feature could cause the
driving wheels to spin, which could result in
skidding.
Coast ing mode
Applies to: vehicles with automatic gearbox
In coasting mode, you can use the vehicle's kinet­
ic energy to drive without using the accelerator
on certain stretches of road. This saves fuel by al­
lowing you to take your foot off the accelerator
earlier and let the vehicle coast (for instance
when approaching a speed restriction in a built­
up area).
Switching on coa sting mode
Important: Selector lever must be in D, gradient
must be less than 12 %.
� Select efficiency mode in drive select*
¢page 100 (you only have to do this once).
� Take your foot off the accelerator.
If you have selected the "on-board computer"
display, the message Coasting mode will then
appear. The gearbox automatically disengages
the clutch at speeds above 20 km/h and lets the
vehicle coast without the engine braking effect.
The engine ticks over at idling speed while the ve­
hicle is coasting.
Stopping coasting mode
� Press the brake pedal or accelerator.
To use the engine braking effect and overrun fuel
cut-off again, all you need to do is tap the brake
pedal briefly.
You can improve your fuel economy and help to
reduce emissions by using a combination of the
