2021 AUDI TT instrument cluster

Sitting correctly and safely

has been certified for “suppression” for infants
approximately 12 months old and younger, and
for “low risk deployment” for children aged 3 to
6 years old (as defined in the standard).
The advanced airbag system will activate or deac-
tivate the front passenger's airbag based on the
occupancy of the seat. If a front airbag deploys
during an accident, the deployment force will
adapt to the passenger.
Components
The advanced airbag system consists of the fol-
lowing components:
— Front airbags in the steering wheel and in the
instrument panel on the front passenger's side:
these can protect the front passengers during
an accident
— Passenger occupant detection sensor in the
front
passenger's seat: this detects if the front
passenger's seat is occupied (for example, by a
person or asmall child in a child safety seat)
— Seat position sensors on the front seats: these
determine the distance between the seat and
the steering wheel or instrument panel
— Sensors in the front seat belt latch: these de-
tect if the safety belts are fastened
— PASSENGER AIR BAG OFF 8%; ON ® indica-
tor light in the headliner:this indicates if the
front passenger's airbag is activated or deacti-
vated
- indicator light in the instrument cluster:
this monitors the function of the Advanced Air-
bag System components to ensure they are
functioning correctly
How the components function together
The passenger occupant detection sensor in the
front passenger's seat detects if the front pas-
senger's seat is occupied. The passenger occu-
pant detection sensor measures the electrical ca-
pacity on the front passenger’s seat. The pas-
senger's airbag is activated or deactivated de-
pending on the electrical capacity that is meas-
ured.
The passenger's airbag is activated if:
56
— The electrical capacity is higher than the
threshold stored in the control module
— The electrical capacity is the same as or greater
than the electrical capacity of a typical adult
The passenger's airbag is deactivated if:
— The electrical capacity is lower than the thresh-
old stored in the control module
— The electrical capacity is the same as or less
than the electrical capacity of a typical one-
year-old child in a child safety seat that has
been used for certification in accordance with
FMVSS 208
If the front passenger's airbag is activated, the
PASSENGER AIR BAG ON @ indicator light
will turn on. If the front passenger's airbag is de-
activated, the PASSENGER AIR BAG OFF #;
indicator light will turn on.
The deployment force of the front airbags adapts
based on whether or not the safety belt is used
and the distance between the seat and the steer-
ing wheel/instrument panel. For example, if a
person is too close to the front airbag, the front
airbag will deploy with less force to help reduce
the risk of injury.
Meaning of PASSENGER AIR BAG OFF #4, ON
® indicator light
When the ignition is switched on, the system de-
tects whether the front passenger's seat is occu-
pied. PASSENGER AIR BAG OFF #;, ON @
will turn on for several seconds during this proc-
ess. Then it will indicate whether the front pas-
senger's airbag is activated or deactivated.
— PASSENGER AIR BAG OFF 8%; the front
passenger's airbag is deactivated and will not
deploy in the event of an accident.
— PASSENGER AIR BAG ON @: the front pas-
senger's airbag is activated and could deploy in
the event of an accident.
If a change to the occupancy status of the front
passenger's seat is detected
PASSENGER AIR BAG OFF #, ON @ will
flash for several seconds and will then display the
status of the front passenger's airbag.

appears in the instrument cluster once the en-
gine stops automatically.
> The engine starts again when you remove your
foot from the brake pedal. The indicator light
turns off.
Additional information for automatic
transmissions
The engine stops in the "P", "N" and "D" selector
lever positions.
If you select the “R” gear during a Stop phase
while pressing the brake pedal, the engine will
start again.
Shift to "P" quickly to prevent the engine from
starting unintentionally when shifting through
"RM.
You can control if the engine will stop or not by
reducing or increasing the amount of force you
use to press the brake pedal. For example, if you
only lightly press on the brake pedal in stop-and-
go traffic or when turning, the engine will not
switch off when the vehicle is stationary. If you
press the brake pedal harder, the engine will
switch off.
@) Tips
— Press the brake pedal during a Stop phase
to keep the vehicle from rolling.
— The ignition will turn off if you press the
START ENGINE STOP] button during a Stop


phase.
— When you stop and the Start/Stop system
turns the engine off, the ignition remains
on. Make sure the ignition is switched off
before you leave the vehicle or else the bat-
tery could drain.
General information
Applies to: vehicles with Start/Stop system
Starting and stopping the engine automat-
ically
The system checks if certain conditions are met
before and during the Stop phase, and deter-
mines if the engine stops and how long it re-
mains stopped. For example, if power usage is
high, the engine will not be stopped. Along with
78
other conditions, the following factors influence
the automatic engine start or stop:
— Environmental conditions (slopes, inclines, ele-
vation, temperature)
— Battery (charge status, temperature, power us-
age)
— Engine temperature
— Assist systems
— Driving behavior
Depending on the engine, the indicator light
may appear if the engine is not stopped.
Ignition is switched off automatically
To prevent the vehicle battery from draining, the
ignition will switch off automatically under the
following conditions:
— If the vehicle has already been driven
— If the Start/Stop system has stopped the en-
gine
— If the driver's door is opened
— If the driver's safety belt is unbuckled
— If the brake pedal is not pressed
— If the vehicle is stationary
In this case, the parking lights switch on in place
of the low beams and the message Side marker
lights will switch off automatically in 30 mi-
nutes. See owner's manual appears in the Info-
tainment system display. The side marker lights
will switch off after approximately 30 minutes or
when you lock the vehicle.
If the Start/Stop system has not turned off the
engine or if you have switched the Start/Stop sys-
tem off manually, the ignition will not be auto-
matically switched off and the engine will contin-
uetorun>A.

ZA WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
G) Tips
If you select the “D” or “N” selector lever posi-
tion after shifting into reverse, the vehicle
must be driven faster than 6 mph (10 km/h)
in order for the engine to switch off again.

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.

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

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.
