2021 AUDI TT power steering

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.

80
@) 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 >

Driving

You can shift the gears manually when in “D”
mode. The transmission must be in tiptronic
mode.
Shifting with the selector lever
You can shift into manual shifting mode while the
vehicle is stationary or while driving.
> To switch to manual shifting mode, tilt the se-
lector lever toward the front passenger's side
> fig. 90. “M” will be displayed in the instru-
ment cluster.
> Upshifting: push the selector lever forward G).
> Downshifting: push the selector lever toward
the rear ©).
> To switch back to automatic mode, tilt the se-
lector lever toward the driver's side.
Shifting with the shift paddles
Applies to: vehicles with shift paddles
> Upshifting: press the @) shift paddle © fig. 97.
> Downshifting: press the ©) shift paddle.
» Applies to: RS models: To select the lowest/
highest possible gear, press and hold the shift
paddle @)/@).
If the shift paddles are tapped while in the D/S
selector lever position, automatic mode switches
off briefly. To switch from manually shifting back
to automatic shifting immediately, tap the shift
paddle @) © fig. 97 for 1 second.
To keep shifting manually, tilt the selector lever
toward the front passenger's side.
@ Tips
— The transmission only allows manual shift-
ing when the engine speed is within the per-
mitted range.
— The transmission automatically shifts up or
down before critical engine speed is
reached.
— Applies to: RS models: When accelerating,
the transmission will not automatically shift
to the next gear shortly before the maxi-
mum permitted engine RPM is reached.
Shift to the next highest gear at the right
time.
86
Kick-down enables maximum acceleration.
When you press the accelerator pedal down be-
yond the resistance point, the automatic trans-
mission downshifts into a lower gear and the en-
gine utilizes its full power, if the vehicle speed
and engine RPM permit. It shifts up into the next
higher gear once the maximum permitted engine
RPM is reached.

ZA\ WARNING
Please note that the wheels could spin on
slick or slippery roads when kick-down is ac-
tive.
Launch Control
Applies to: vehicles with Launch Control

Launch Control provides the best possible accel-
eration when starting from a stop.
Requirements
— The engine must be at operating temperature.
— The steering wheel must not be turned.
— Start/Stop system* must be deactivated
=> page 79.
— ESC must be limited > page 105.
— Driving program “S” > page 82 or the Dynamic
Audi drive select* mode must be selected

Using Launch Control
— Press the brake pedal with your left foot and
hold it all the way down for at least one second.
— With the brake pedal pressed, press the accel-
erator pedal all the way down with your right
foot at the same time.
— Once the engine reaches a constant speed, re-
move your foot from the brake pedal.
Once the vehicle has started moving, reactivate
the ESC so that it is fully functional.

ZA WARNING
Only use Launch Control when road and traffic
conditions allow it and other road users will
not be endangered or impacted by your >

The system cannot guarantee that it will detect
vehicles correctly and it has switched off. The
sensors have been moved or are faulty. Have the
system checked by an authorized Audi dealer or
authorized Audi Service Facility soon.
Audi drive select (drive
settings)
Introduction
Applies to: vehicles with Audi drive select
Drive select makes it possible to experience dif-
ferent types of vehicle characteristics in one vehi-
cle. With different driving modes, the driver can
switch the setting, for example from sporty to
comfortable. In the Individual mode, the set-
tings can be adjusted to your personal preferen-
ces. This makes it possible to combine settings
such as a sporty drivetrain setting with comforta-
ble steering.


Using Audi drive select incorrectly can lead to
collisions, other accidents and serious inju-
ries.

Applies to: vehicles with Audi drive select

The vehicle setup in each mode depends on the
vehicle's features.
Engine and automatic transmission
Depending on the mode, the engine and auto-
matic transmission respond more quickly or ina
more balanced manner to accelerator pedal
movements.
Suspension control (Audi magnetic ride)*
The suspension control uses sensors to record in-
formation regarding steering movements, brak-
ing and acceleration operations by the driver, as
well as information about the road surface, driv-
ing speed, and load. With drive select, you can
adjust the suspension control to sporty (dynam-
ic), comfortable (comfort) or balanced (auto).
96

Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especially
suited to long drives on a highway. The dynamic
mode provides sporty, direct steering.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.


— Certain vehicle settings will be reset when
the ignition is switched off.
— In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
Selecting the driving mode
Applies to: vehicles with Audi drive select
You can choose between comfort, auto, dynamic
and individual.

Electronic Stabilization
Control (ESC)
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations such as the vehicle oversteering and un-
dersteering or the wheels are spinning. The
brakes are applied or the motor torque is reduced
in order to stabilize the vehicle. When the ESC
engages, the B indicator light flashes in the in-
strument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak-
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle.
Brake assist
The brake assist system can decrease braking dis-
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit-
uations. You must press and hold the brake pedal
until the dangerous situation is over.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly.
EDL will switch on again automatically when con-
ditions have returned to normal.
104
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision above a certain ve-
hicle speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal
—The braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

Z\ WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this

— Utilize the engine braking effect when driv-
ing downhill by selecting the “S” driving
program > page 82. This reduces the load
on the brakes. If you need to brake addition-
ally, brake in intervals and not continuously.
G) Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.
— Also refer to the information about brake
fluid > page 209.

hicle
There is a malfunction in the brake system. If
[ES / Gana Blalso turn on, there is a malfunc-
tion in the ABS, ESC, and braking distribution. If
the brake booster is not working, you have to use
much more force when braking the vehicle.
Do not continue driving. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance. Read and follow the other safety pre-
cautions > A\.
GG / @ Warning! No brake booster function
If the brake booster is not working, you have to
use much more force when braking the vehicle.

All wheel drive (quattro)
Applies to: vehicles with all wheel drive

The all-wheel drive system distributes the driving
power variably to the front and rear axle to im-
prove the driving characteristics. It works togeth-
er with selective wheel torque control, which can
activate when driving through curves
=> page 104.
The all-wheel drive system is designed for high
motor power. Your vehicle is exceptionally power-
ful and has excellent driving characteristics both
under normal driving conditions and on snow and
ice. Always read and follow safety precautions
>A.

Z\ WARNING
— Even in vehicles with all wheel drive, you
should adapt your driving style to the cur-
rent road and traffic conditions to reduce
the risk of an accident.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not drive too fast because this in-
creases the risk of an accident.

108

— Note that on wet streets, the front wheels
can “hydroplane’” if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the motor RPM does not increase
suddenly when the vehicle begins hydro-
planing. Adapt your speed to the road condi-

tions to reduce the risk of an accident.

road.
For the most safety and security, drive with a tow
bar. You should use a towing cable only if a tow
bar is not available. Use a towing cable made of
synthetic elastic cable similar elastic material.

ZA\ WARNING
— Towing highly increases the risk of an acci-
dent, for example from colliding with the
towing vehicle.
— To reduce the risk of an accident, do not al-
low anyone to remain inside the vehicle
when it is being transported by a tow truck
or a special transporter.

® Note
— If normal towing is not possible, for exam-
ple if the transmission is faulty or if the
towing distance is greater than 30 miles
(50 km), then transport the vehicle ona
special carrier.
— If the vehicle is towed by a tow truck at the
axle that is not permitted, this can cause se-
vere damage to the transmission.
— The vehicle must not be tow started for
technical reasons.
G) Tips
— If there is a power failure, the selector lever
will not move out of the "P" position. The
parking lock must be released using the
emergency release before towing the vehi-
cle > page 88.
— Follow the local legal regulations for tow-
ing.
