2021 AUDI TT Brake assist

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.

@) 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.

ZA\ WARNING
—To reduce the risk of an accident, always
make sure the vehicle is situated safely
while stationary.
— 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.
— If the power supply fails, you cannot set the
parking brake once it is released, or release
it if it is set. In this case, park the vehicle on
level ground and secure it by engaging the
"P” gear. Contact an authorized Audi dealer
or authorized Audi Service Facility for assis-
tance.

ZA WARNING
— If you do not begin driving immediately after
releasing the brake pedal, your vehicle may
begin to roll backward. Press the brake ped-
al or set the parking brake immediately.
— The hill hold assist cannot hold the vehicle
on inclines in every scenario (for example,

on slippery or icy ground).

Sporty driving
Applies to: RS models
When driving in a sporty style, the wear on all ve-
hicle components is greatly increased, especially
on the engine, transmission, tires, brakes, and
suspension. This can result in increased wear. Al-
so
note the following points:
— Make sure the vehicle is in good condition.
Make sure to check the brake pads, tire tread,
and tire pressure (when tires are warm).
— Beforehand, warm up the engine by driving no
higher than two-thirds of the maximum permit-
ted engine RPM. The engine oil must be
brought to a minimum temperature of 158 °F
(60 °C).
— Before stopping the vehicle, allow the engine
and brakes to cool back down to a regular oper-
ating temperature by driving normally.
If necessary, use the following functions:
— Dynamic Audi drive select mode* > page 96
— Launch Control > page 86
— Limit ESC > page 105
@) Tips
Wear caused by load does not constitute a ve-
hicle fault as defined by the terms of the war-
ranty.
Automatic transmission
Introduction
Your vehicle is equipped with an electronically-
controlled DSG transmission called S tronic. Two
independent clutches transfer the power be-
tween the engine and transmission. It allows the
vehicle to accelerate without a noticeable inter-
ruption in traction.
The transmission shifts up or down automatically
depending on which drive program is selected.
When a moderate driving style is used, the
transmission selects the most economical driving
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a sporty driv-
ing style characterized by quick accelerator pedal
movements, heavy acceleration, frequent
changes in speed, and traveling at the maximum
speed.
If desired, the driver can also select the gears
manually (tiptronic mode) > page 85.

To release the selector lever lock:
> Switch the ignition on.
> Press the brake pedal while pressing the inter-
lock button.
Automatic shift lock (ASL)
The selector lever is locked in the "P" and "N" po-
sitions when the ignition is switched on. You
must press the brake pedal to select another po-
sition. You must also press the interlock button if
you are moving from the "P" position. The follow-
ing message appears in the display when the se-
lector lever is in the "P" or "N" position to remind
the driver:
To select a gear, please press brake pedal and
press lock button on selector lever
The automatic shift lock only functions when the
vehicle is stationary or at speeds below 1 mph
(2 km/h). At higher speeds, the lock is automati-
cally deactivated in the "N" position.
The selector lever is not locked when shifting
quickly through "N", for example from "R" to "D".
This makes it possible to free the vehicle when it
is stuck by “rocking” it. The selector lever lock en-
gages if the lever stays in the "N" position longer
than approximately two seconds when the brake
pedal is not pressed.
Interlock button
The interlock button in the selector lever handle
prevents you from moving the selector lever in-
advertently while in some selector lever posi-
tions. The positions that require the interlock
button to be pressed are marked in color in the il-
lustration > fig. 88.

Z\ WARNING
Read and follow all WARNINGS. > A\ in Selec-
tor lever positions on page 82.
G) Tips
— If the selector lever does not engage, there
is a malfunction. The engine is disabled to
prevent the vehicle from driving off uninten-
tionally. To allow the selector lever to en-
gage again, proceed as follows:
— Briefly press the brake pedal.
— If the vehicle does not move forward or in
reverse even though a drive position is se-
lected, proceed as follows:
— If the vehicle does not move in the desired
direction, the system may not have engaged
the drive position correctly. Press the brake
pedal
and select the drive position again.
— If the vehicle still does not move in the de-
sired direction, there is a system malfunc-
tion. See an authorized Audi dealer or au-
thorized Audi Service Facility for assistance
to have the system checked.


The transmission shifts up and down automati-
cally when in the driving gears.

Driving


— If the engine must run while you are working
in the engine compartment with the hood
open, make sure a gear is not engaged. The
selector lever must be firmly in the P posi-
tion and locked in place and the parking
brake must be set > page 200. Otherwise,
the vehicle could begin moving when in-
creasing the engine speed, even with the

parking brake set.

() Note
— If you have to stop on an incline, always
press the brake pedal to hold the vehicle in
place to reduce the risk of the vehicle rolling
backward. Do not try to hold the vehicle in
place by pressing and holding the accelera-
tor pedal. The transmission can overheat,
which increases the risk of damage.
— Allowing the vehicle to roll when the engine
is stopped and the selector lever is in the N
position will damage the automatic trans-
mission because it is not lubricated under
those circumstances.
— The transmission can overheat and be dam-
aged under certain driving and traffic condi-
tions such as frequent starts, creeping fora
long time, or stop-and-go traffic. When the
i or os] indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool > page 87.
— Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans-
mission because it is not lubricated
= page 250, Towing.
@® Tips
For safety reasons, the parking brake is re-
leased automatically only when the driver's
safety belt is fastened.
Hill descent control
The hill descent control system assists the driver
when driving down hills.
Hill descent control is activated when the selec-
tor lever is in the "D" or "S" position and you
press the brake pedal. The transmission auto-

matically selects a gear that is suitable for the
hill. Hill descent control tries to maintain the
speed that was selected at the time of braking,
within physical and technical limitations. If may
still be necessary to adjust the speed with the
brakes. Because hill descent control cannot shift
down farther than 3rd gear, it may be necessary
to shift into tiptronic mode in very steep areas. In
this case, shift manually into 1st or 2nd gear in
tiptronic mode to use the engine's braking force
to relieve the brakes.
Hill descent control switches off once the hill lev-
els
out or if you press the accelerator pedal.
On vehicles with a cruise control system*
= page 89, hill descent control is also activated
when the speed is set.

ZA\ WARNING
Hill descent control may not be able to main-
tain a constant speed under all conditions. Al-
ways be ready to apply the brakes.
Shifting manually (tiptronic mode)
The tiptronic mode allows the driver to shift the
gears manually.

driving and the vehicle's acceleration. The
driving wheels could spin and the vehicle
could swerve, especially on slick or slippery
road surfaces, which increases the risk of an
accident.

@) Note
When accelerating using Launch Control, all
vehicle components are subject to heavy
loads. This can result in increased wear.
G) Tips
After accelerating using the Launch Control,
the temperature of some vehicle components
may increase greatly. If that happens, the
function will not be available for a few mi-
nutes to reduce the risk of damage. After a
cool-down period, Launch Control will be
available again.

Assist systems
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps the driver to
stay below a specified maximum speed. A warn-
ing threshold can be set in the Infotainment sys-
tem for this purpose.
Once the speed slightly exceeds the stored
threshold, the speed warning system will alert
the driver with an indicator in the instrument
cluster and a warning tone. Once the speed drops
below the stored maximum speed, the indicator
will turn off.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
@) Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are adhering
to the legal speed limit.
Setting the warning threshold
Applies to: vehicles with speed warning system

> Select in the Infotainment system: [MENU] but-
ton > Vehicle > left control button > Driver as-
sistance > Speed warning > Manual.
Messages
Applies to: vehicles with speed warning system
ol Manually set speed limit XX mph
(km/h) exceeded

The stored speed was exceeded.
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.

ZA WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions
are poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
@) Note
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and reduces the load placed on
the brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.
