2021 AUDI TT warning light

Driving

Starting the engine
> The selector lever must be in the P or the N po-
sition.
At low temperatures (below 14 °F (-10 °C)), the
engine can only be started when the selector lev-
er is in the "P" position.
Starting from a stop
> Press and hold the brake pedal.
> Start the engine > page 75.
> Press and hold the interlock button in the selec-
tor lever handle, select the desired selector lev-
er position such as "D" > page 87 and release
the lock button.
> Wait a moment until the transmission shifts.
You will notice a slight movement when the
gear engages.
> Release the brake pedal and press the accelera-
tor pedal > A\.
Various convenience functions are available for
starting on hills > page 80.
Stopping temporarily
> Press the brake pedal to stop the vehicle, for
example at a traffic light. Do not press the ac-
celerator pedal when doing this.
> To prevent the vehicle from rolling when you
start driving, set the parking brake when stop-
ping on steep hills > A\ and >@).
> The parking brake will release automatically
and the vehicle will start moving once you press
the accelerator pedal.
Stopping/parking
If the selector lever is not in the "P" position
when you open the driver’s door, the vehicle
could roll.
In vehicles with a convenience key*, the message
Shift to P, otherwise vehicle can roll away.
Doors do not lock if gearshift is not in P ap-
pears. A warning tone will also sound.
> Press and hold the brake pedal > A\.
> Set the parking brake.
> Select the "P" selector lever position.
Under certain circumstances, such as driving in
the mountains, it may be useful to switch tempo-
84
rarily to tiptronic mode in order to manually ad-
just the gears to the driving conditions
=> page 85.
On
hills, activate the parking brake first and then
shift into the "P" selector lever position. This pre-
vents too much stress from being placed on the
locking mechanism.

ZA WARNING
— The vehicle can roll even when the engine is
switched off.
— Unintended vehicle movement can lead to
serious injuries.
— Never leave your vehicle with the engine
running while in gear. If you must leave your
vehicle when the engine is running, set the
parking brake and move the selector lever to
the P position.
— Power is still transferred to the wheels when
the engine is running at idle. To prevent the
vehicle from “creeping”, you must keep your
foot on the brake when the engine is run-
ning and the selector lever is in the "D", "S"
or
"R" position or “tiptronic” mode is select-
ed.
— Do not inadvertently press the accelerator
pedal when the vehicle is stationary. Other-
wise the vehicle will start to move immedi-
ately, even if the parking brake is set. This
could result in a crash.
— Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
— Never engage the R or P selector level posi-
tions while driving. It could cause a crash.
— Before driving down a steep slope, reduce
your speed and shift into a lower gear with
“tiptronic”.
— Do not ride the brakes or press the brake
pedal
too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and can substantially re-
duce braking performance, increase braking
distance, or cause complete failure of the
brake system.

8S1012721BE
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.

— The parking lock may only be released using
the emergency release if the parking brake
is set. If it is not working, secure the vehicle
from rolling using the brake pedal or other
suitable means, such as blocking a front and
a rear wheel. An unsecured vehicle may roll,
which increases the risk of an accident.
— Only activate the emergency release while
ona level surface or a slight slope.
—To reduce the risk of an accident, you must
not drive when the emergency release is ac-

tivated.

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.

Parking aid

Parking aid
Introduction
Applies to: vehicles with rear parking system/parking system
plus
Depending on the vehicle equipment, various
parking aids will help you when parking and ma-
neuvering.
The rear parking system is an audible parking aid
that warns you of obstacles behind the vehicle
=> page 98.
The parking aid plus assists you while parking by
audibly and visually warning you of objects de-
tected in front of and behind the vehicle
=> page 99.
The rearview camera shows the area behind the
vehicle in the Infotainment system display. The
lines in the rearview camera image help you to
park or maneuver > page 700.

ZA WARNING
— Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The systems cannot replace the
driver's attention. The driver is always re-
sponsible when entering or exiting a parking
space and during similar maneuvers.
— Please note that some surfaces, such as
clothing, are not detected by the system.
— Sensors and cameras have blind spots in
which people and objects cannot be detect-
ed. Be especially cautious of small children
and animals.
— The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park-
ing aid may be impaired as a result. Have an
authorized Audi dealer or authorized Audi
Service Facility check their function.
— Make sure the sensors are not obstructed by
stickers, deposits or other materials. If they
are, the sensor function could be impaired.
For additional information on cleaning, see
> page 236.

@) Note
— Some objects are not detected or displayed
by the system under certain circumstances:
— objects such as barrier chains, trailer draw
bars, vertical poles or fences
— objects above the sensors such as wall ex-
tensions
— objects with certain surfaces or structures
such as chain link fences or powder snow
— If you continue driving closer to a low ob-
ject, it may disappear from the sensor
range. Note that you will no Longer be
warned about this obstacle.
— Maintain enough distance from the curb to
reduce the risk of damage to the rims.
@) Tips
— The system may provide a warning even
though there are no obstacles in the cover-
age area in some situations, such as:
— certain road surfaces or when there is tall
grass
— external ultrasonic sources such as from
cleaning vehicles
—in heavy rain, snow, or thick vehicle ex-
haust
— Audi recommends practicing parking ina
traffic-free location or parking lot to be-
come familiar with the systems. Practice
parking in good light and weather condi-
tions.
— You can change the volume of the signals.
— What appears in the display is slightly de-
layed.
— The sensors must be kept clean and free of
snow and ice for the parking aid to operate.
Rear parking system
Applies to: vehicles with rear parking system
The rear parking system is an audible aid.
Description
There is a sensor in the rear bumper cover. If
these detect an obstacle, audible signals warn
you.

Intelligent Technology

Intelligent Technology
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
