2019 AUDI TT ROADSTER engine

Assist systems

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).
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.
@ Tips
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 engine torque is re-
duced in order to stabilize the vehicle. When the
ESC engages, the B indicator light blinks in the
instrument 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 system
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 drive wheels
begin spinning and adapts the power to the road
conditions. This makes it easier to start, acceler-
ate and drive up hills.
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.
86
EDL will switch on again automatically when con-
ditions have returned to normal.
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

ZA 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. The ESC and
its integrated systems cannot always pre-
vent collisions - there is still a risk of acci-
dents!

— There is no vehicle stabilization when
ESC/ASR are switched off.

@) Tips
— When the cruise control system* is switched
on, ESC/ASR cannot be switched off or sport
mode cannot be switched on.
— Malfunctions in the rear spoiler or the Audi
magnetic ride may make it impossible to
switch the ESC/ASR off or to switch sport
mode on.
Brakes
You can apply the vehicle's brakes using the brake
pedal.
Operating noise
Noises may occur when braking depending on the
speed, braking force, and outside conditions such
as temperature and humidity.
Braking effect
The response time from the brakes depends on
the weather and environmental conditions. To
ensure the optimum braking effect, the brake
system is cleaned at regular intervals. This is
done by applying the brake pads to the brake ro-
tors for a short period of time when driving at
high speeds when the windshield wipers are
switched on.
If the brake system becomes damp, for example
after driving in heavy rain, the braking effect may
be delayed. Other factors that could temporarily
increase the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
Corrosion
Corrosion may form on the brake rotors if there is
no heavy braking, if the vehicle is not driven for
long periods of time, or if the vehicle is not driv-
en
frequently or for long distances. In this case,
braking heavily several times while driving at
high speeds can clean the brake rotors > A\.
838
Brake pads
New brake pads do not achieve their full braking
effect during the first 250 miles (400 km). They
must be “broken in” first. However, you can com-
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period.
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
Brake pad wear increases when driving frequently
in the city or short distances or when using a very
sporty driving style.
Ceramic brakes
Applies to: vehicles with ceramic brakes
Ceramic brakes provide excellent deceleration
rates.
The break-in period for new ceramic brakes may
be significantly longer than for standard brake
rotors. Due to the properties of the material,
they may cause noises at lower speeds. Ceramic
brakes also absorb more moisture in wet condi-
tions. Therefore, there will temporarily be less
braking force than when the brakes are dry. You
can compensate for this by pressing the brake
pedal harder.

A WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users and increase the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
— Depending on vehicle equipment, the brake
pedal may move downward automatically
during autonomous braking maneuvers. To
reduce the risk of injury, do not place your
foot under the brake pedal.

@) Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually
necessary. This can cause the brakes to over-
heat and increases braking distance and
causes wear.
— Before driving on long stretches with steep
hills, reduce the vehicle speed and shift to a
lower gear to use the engine braking effect.
This reduces the load on the brakes. If you
need to brake additionally, brake in intervals
and not continuously.
@) 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 235.
Steering
Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
speed. The settings depend on the selected Audi
drive select* mode.
a Steering: malfunction! Please stop vehicle
The power steering may have failed. Adapt your
driving style immediately to compensate for the
fact that it may be more difficult to turn the
steering wheel, and stop your vehicle in a safe lo-
cation as soon as possible. Do not continue driv-
ing. See an authorized Audi dealer or authorized
Audi Service Facility for assistance.
a Steering: malfunction! You can continue
driving
There is a malfunction. Steering may be more dif-
ficult or more sensitive. Adapt your driving style.
Have the steering system checked immediately
by an authorized Audi dealer or authorized Audi
Service Facility. Please note that the red indicator
light may turn on after restarting the engine. Do
not continue driving if it does.
G@) Tips
If the 12 or al indicator light only stays on
for a short time, you may continue driving.
ALL wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all wheel drive, the driving power is divided be-
tween all four wheels. This happens automatical-
ly depending on your driving behavior as well as
the current road conditions. Also see > page 86,
Electronic stabilization control (ESC).
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre-
cautions > A\.
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con-
ditions. However, in winter we recommend using
winter or all season tires on all four wheels, be-
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
=> page 255, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used.
Avoid using tires with different tread depths
=> page 247, New tires or wheels.

Is this an offroad vehicle?
Your Audi is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.

ZA\ WARNING
— Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci-
dent.
— 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 be tempted to accelerate to a
high speed when the road is slippery, be-
cause this increases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane’” if driving at speeds that
are too high. Unlike front wheel drive vehi-
cles, the engine RPM does not increase sud-
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci-
dent.

Rear spoiler
Applies to: vehicles with retractable rear spoiler
The extendable rear spoiler increases driving sta-
bility.

Automatic mode (normal operation)
— Automatic extension: the rear spoiler will auto-
matically extend when speeds exceed approxi-
mately 75 mph (120 km/h).
— Automatic retraction: the rear spoiler will auto-
matically retract when speeds decrease to un-
der approximately 50 mph (80 km/h).
Manual mode
— Extending manually: briefly tap the > fig. 92
button to fully extend the rear spoiler.
— Retracting manually: when driving at speeds
below approximately 10 mph (20 km/h), press
and hold the button to retract the rear spoiler.
When at speeds between 10 mph (20 km/h)
and 75 mph (120 km/h), the rear spoiler will
completely retract when you tap the button.
Indicator lights
8 / | Rear spoiler: malfunction! Please con-
tact Service
The rear spoiler may not have extended due toa
malfunction. This could change the vehicle's driv-
ing characteristics at high speeds. Do not drive
faster than 85 mph (140 km/h). Drive to an au-
thorized Audi dealer or authorized Audi Service
Facility immediately to have the malfunction cor-
rected. The color of the indicator light depends
on the vehicle speed.

ZA WARNING
Driving at higher speeds without the rear
spoiler deployed can impair handling charac-
teristics, making the vehicle harder to control.
— Always make sure that the spoiler is de-
ployed when driving at speeds over 85 mph
(140 km/h). If the rear spoiler warning/indi-
cator light in the instrument cluster comes
on, the rear spoiler may not have deployed.
— Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed.
Have the spoiler inspected as soon as possi-
ble by an authorized Audi dealer or qualified
workshop.
— Always obey speed limits and other traffic
laws.

ZA\ WARNING
Improper operation of the rear spoiler can
cause crushing injuries.
— Always make sure that nobody, especially
children, is in the way when the rear spoiler
is deployed or retracted.

() Note
— Never push on the vehicle on the rear spoil-
er. This could cause damage.
— To prevent damage to the rear spoiler do
not lean or place anything on it.
— Only operate the rear spoiler manually when
the luggage compartment lid is close and
the rear spoiler moving parts are not
blocked. Otherwise, damage could occur.
@ Tips
Clean the rear spoiler compartment every 2 to
3 months. To function correctly, the rear
spoiler must be free of ice, snow and leaves.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
@ Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be limited or
switched off.
Information about data
recorded by vehicle
control modules
Your vehicle is not equipped with a crash data re-
corder. This device is installed by some vehicle
manufacturers to record data about crashes so
that it can be analyzed later. Crash data recorders
are also called “Event Data Recorders (EDR)”.
In some legal jurisdictions, it is not permitted to
access or download data recorded by pre-instal-
led crash data recorders in order to evaluate a
crash without clear consent of the vehicle owner.
Your vehicle is not equipped with a crash data re-
corder. However it does contain a variety of elec-
tronic control modules for various vehicle sys-
tems such as engine function, exhaust treatment
or airbags and safety belts.
These electronic control modules record vehicle
data during normal driving for diagnosis and re-
pair purposes. The recording capability of the
electronic control modules is limited to data only
- no sound is recorded. If the control module de-
tects a system malfunction or other change in
status, a very limited amount of data is recorded
for an extremely small period of time. Data that
is recorded in such a case may include vehicle
speed, driving direction, the load on the brakes
and head restraints and performance in the event
of an accident or other change in status. The stor-
ed data can only be read or downloaded with spe-
cial devices.
