2018 AUDI TT ROADSTER engine

Driving
keep your foot on the brake in all selector
lever positions (except P) when the engine is
running. Otherwise, this increases the risk
of an accident.
- Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged. Otherwise the vehicle will start to
move immediately, 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 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 lev­
er to the "P" position.
- To decrease the risk of an accident, these­
lector lever must be in the P position and
the parking brake must be set before open­
ing the hood and working on a running en­
gine. Always read and follow the applicable
warnings¢ page 233, Working in the en­
gine compartment .
(D Note
Never let the vehicle roll downhill with engine
off and the selector lever in the "N" position,
because this could damage the automatic
transmission and catalytic converter .
{D) Tips
- Drive select: sporty shifting characteristics
can be selected using the
Dynamic driving
mode . The Infotainment display shows Sas
the selector lever position instead of D.
- If you accidentally select "N" while driving,
take your foot off the accelerator pedal im­
mediately and wait for the engine to slow
down to idle before selecting "D" or "S".
- If there is a power failure, the selector lever
will not move out of the "P" position. The
emergency release can be used if this hap­
pens. Left-hand drive

Driving
When parking on a level surface, simply place the
selector lever in the "P" position. On inclines, ac­
tivate the parking brake first and then move the
selector lever to the "P " position
c> page 61 . This
prevents the locking mechanism from being
loaded too heavily and will make it easier to
move the selector lever out of the "P" position.
A 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 lev­
er to the P position.
- Power is still transferred to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake when the en­
gine is running and the selector lever is in
the "D" , "S" or "R" position or "tiptronic"
mode is selected.
- 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
"ti ptron i c" .
- 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 substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- If you must stop on an incline, always hold
the vehicle in place with the foot brake or
66
parking brake to prevent it from rolling
back .
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. The
ml indicator light turns on
and a message appears
c> page 68 when
the clutch is overloaded .
- If the engine must run while you are work­
ing in the engine compartment with the
hood open, make sure a gear is not engag­
ed. The selector lever must be firmly in the
P position and locked in place and the park­
ing brake must be set
c> page 233. Other­
wise, the vehicle could begin moving when
increasing the engine speed, even with the
parking brake set.
@ Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­
lected. This can cause the automatic trans­
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- 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
ml or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool
c> page 68.
- Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans­
mission because it is not lubricated
c> page 285, Towing with a tow truck .
(D 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 transm iss ion auto ­
mat ically selects a gear that is suitable for the
h ill. Hill descent con trol tries to maintain the
speed ach ieved at the t ime of b raking, w ith in
phys ica l and technical limi tatio ns. If may still be
necessa ry to adjust the speed with the brakes .
Because hill descent contro l cannot sh ift 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
tiptron ic mode to use the engine 's braking force
to relieve the brakes .
Hill descent control switches off once the hill lev ­
els out or you press the accelerator pedal.
On vehicles with a cruise contro l system*
¢ page 71, hill descent control is also activated
when the speed is set .
A WARNING
Hill descent control cannot overcome physical
limitations , so it may not be able to maintain
a constant speed under all condit ions . Always
be ready to apply the brakes .
Shifting manually (tiptronic mode)
The tiptronic mode allows the driver to shift the
gears manually .

ries.
Description
App lies to: vehicles with A udi drive se lect
The veh icle 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 in a
more balanced manner to accelerator pedal
movements.
Suspension control (Audi magnetic ride)*
The suspension control uses sensors to record in­
format ion regarding steering movements, brak­
i ng and acceleration operations by the driver, as
well as information about the road surface, driv­
i ng speed, and load. W ith dr ive se lect, you can
adjust the suspension control to sporty (dynam­
ic ), comfortable (comfort) or balanced (auto).
Steering
The power steering adapts . Indirect steering that
moves eas ily as in comfort mode is espec ially
su ited 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 .
(D Tips
In some models, the maximum vehicle speed
can only be reached in the auto and dynamic
modes .
