2020 AUDI TT COUPE engine overheat

8S1012721BB
Instrument cluster

@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.
— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa-
cility for assistance.
Tachometer
The tachometer @) > page 10, fig. 3 displays the
engine speed in revolutions per minute (RPM).
The beginning of the red zone in the tachometer
indicates the maximum permissible engine speed
for all gears once the engine has been broken in.
Before reaching the red zone, you should shift in-
to the next higher gear, choose the "D" or "S" se-
lector lever position, or remove your foot from
the accelerator pedal.
Engine speed limitation
Applies to: vehicles with center armrest
If the Ba indicator light turns on, the engine will
be automatically limited to the RPM displayed in
the instrument cluster. This will protect the en-
gine components, for example during a cold start
or from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature
range and you have released the accelerator ped-
al once.
If the engine speed limitation was activated by
an engine control malfunction, the By indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam-
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im-
mediately to have the malfunction corrected.
CG) Note
The needle in the tachometer may only be in
the red area of the gauge for a short period of
time before there is a risk of damaging the
engine. The location where the red zone be-
gins varies depending on the engine.
Odometer

Fig. 4 Instrument cluster: odometer and reset button
The trip odometer and odometer are displayed in
the status line ©) > page 10, fig. 3.
The trip odometer shows the distance driven
since it was last reset. It can be used to measure
short distances. The odometer shows the total
distance that the vehicle has been driven.
Resetting the trip odometer

> Press the reset button 0.0] on the instrument
cluster. The trip odometer will be reset to zero.
Gi) Tips

(kilometers).

Outside temperature
display
The outside temperature is displayed in the sta-
tus line ©) > page 10, fig. 3.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the engine.

At temperatures below 41 °F (+5 °C), a snowflake
symbol appears in front of the temperature dis-
play > A.

ZA WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.


Fuel level
The display @ > page 10, fig. 3 only works when
the ignition is switched on. When the display has
reached the reserve mark, a red LED turns on and
the iy indicator light turns on > page 197.
For the tank capacity in your vehicle, refer to the
Technical Data > page 263.
@) Note
Never drive until the tank is completely emp-
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom-
busted fuel will then enter the exhaust sys-
tem. This can cause overheating and damage
to the catalytic converter.

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 79 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 78.
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 following
message appears: Shift to P, otherwise vehicle
can roll away. Doors do not lock if gearshift is
not in P A warning tone will also sound.
> Press and hold the brake pedal > /\.
> 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-
82
rarily to tiptronic mode in order to manually ad-
just the gears to the driving conditions
=> page 83.
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.

8S1012721BB
Driving


— If the engine must run while you are work-
ing in the engine compartment with the
hood open, make sure a gear is not engaged.
The selector lever must be firmly in the
P position and locked in place and the park-
ing brake must be set > page 200. Other-
wise, the vehicle could begin moving when
increasing 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 for a
long time, or stop-and-go traffic. When the
i or ij indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool > page 85.
— Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans-
mission because it is not lubricated
=> page 249, 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 automat-

ically 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 tip-
tronic 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 87, hill descent control is also activated
when the speed is set.

ZX 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.

Intelligent Technology

— Utilize the engine braking effect when driv-
ing downhill by selecting the “S” driving
program > page 80. 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 208.
