2018 AUDI TT ROADSTER stop start

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
Avoid full acceler ation
You sho uld rare ly t rave l a t t he maxim um vehicle
speed . High speeds cause a disproportionately
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the eng ine, for example when
at ra ilroad crossings or traffi c lights w ith longer
red lights . Stopping the engine for 30 -40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
I t takes a very long time in idle to wa rm the en­
gine up to operating tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, you should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Hav e ma intenanc e performed r egularly
By having maintenance performed regu lar ly on
your vehicle, you can he lp to reduce fuel con ­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term va lue but al­
so impacts
fu el con sumpt ion .
A poorly maintained engine can lead to fuel con ­
sumpt ion that is 10% higher than norma l.
A lso check the
o il l evel when refueling . The oil
consumpt ion
depends large ly on the engine load
and speed. It is normal for the oil consumption
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approx imately 3,000 m i (S,000 km) have been
driven.
Avoid short trips
The engine and exhaust clean ing system must
reach their opt imal
op erating temp eratur e to ef­
fective ly reduce consumpt ion and emiss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The eng ine reaches operating
temperature and consumpt ion normalizes only
afte r approx imately
2.5 miles (4 km) .
Driving
@ Note
Do not leave engine idling unattended after
start ing. If warning lights sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle o r other proper­
ty.
@ Note
- Have your ve hicle ma intained properly and
in accordance w ith the service recommenda­
tions i n your Warranty
& Main tenance book­
let. La ck of prope r mai nte nan ce as we ll as
imp rope r use of t he ve hicle will impa ir the
function of the em iss ion cont ro l system and
co uld lead to damage .
- Do not alte r or remove any compone nt o f
t he Emission Contro l System unless ap ­
proved by the man ufacturer .
- Do not alte r or remove any dev ice, s uch as
heat shields, switc hes, ignition wires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
impo rtant ve hicle components.
(D Tips
The cons umption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and T ransport Canada may not co rre­
spond to your actual consumption on the r oad, wh ich w ill vary depending upon veh icle
l oad and speed, road and weather cond itions,

Driving
Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back .
Fig. 6 6 Lever on th e steering column
.., Tilt the lever~ fig . 66 downward ~ .&.
... Bring the steering wheel into the desired posi­
tion .
... Push the lever against the steering column un­
til it is secure.
A WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause se rious injuries .
- Only adjust the steering column when the vehicle is stat io nary so that you do not lose
contro l of the ve hicle.
-
-Adjust the driver's seat or steering wheel so
that there is at least a 10 in (25 cm) d is­
tance between your c hest an d the steering
wheel.
If you do not mainta in this dis tan ce,
you will not be p roper ly protec ted by t he air­
bag system.
- If your physical character istics preven t you
from sit ting at least 1 0 in (25 cm) or more
away from the steering wheel, see if an a u­
tho rized Aud i dea le r or a uthorized Audi
Service Facility can provide adapters that
will help.
- If your face is leve l w ith the steering
wheel,
the a irbag does not prov ide as much protec­
t ion during a collision. A lways make sure
that the steering wheel is level with your
chest.
58
-Always hold the steering wheel with your hands in the 9 o'clock and 3 o'clock pos i­
tions to reduce the risk of injury if the airbag
deploys .
- Never hold the steering wheel in the 12
o'clock position or with both hands on the
rim or the center of the steering wheel. Ho ld ing the steer ing whee l incorrect ly sig­
nificant ly increases the risk of injury to the
hands, a rms and head if the airbag deploys.

Cl 00 .-< N r--­N .-< 0 r--­Vl 00
-Never turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running. If the en­ gine is off, you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually would, this
could lead to accidents and serious injuries.
@ Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately . This re­
duces unnecessary emissions.
(D Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
.,. Bring the vehicle to a full stop.
.,. Move the selector lever into the P position .
... Press the I START ENGINE STOPI button.
Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To switch the engine off, press
the
I START ENGINE STOPI button twice in a row
br iefly or press and hold for longer than two sec­
onds.
A WARNING
- Never turn off the engine before the vehicle has come to a complete stop.
Driving
-Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
. . . . mJunes increases.
-For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes
-even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the result of heat buildup or if the engine is al­
ready warm and the engine compartment is
also heated by the sun's rays.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the
engine is
switched off and there is a risk of damaging
the engine . For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­ matically or it may continue to run (even if
the ignition is switched off) for the following
reasons :
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.

Electromechanical
parking brake
Fig. 69 C ent er co n so le : pa rking brake
Your vehicle is equipped with an electromechani­
cal parking brake
(D <¢ fig. 69. The parking brake
is designed to prevent the vehicle from rolling
unintention ally and replaces the hand brake.
Setting/manually releasing the parking
brake
.. Pull the(®) switch to set the parking brake. The
LED in the switch turns on. The
-(USA mod­
els) . (Canada models) indicator light also
turns on in the instrument cluster display .
.. To release the parking brake manually, press

t ion is switched on and press
the®) switch at
the same time. The LED in the button and the
indicator light in the display turn off .
Releasing the parking brake automatically
Requirement: the driver's door must be closed
and the parking brake must be set.
.. To start driving and release the parking brake
automatically, press the accelerator pedal as
usual.
In addi tion to releasing the parking brake au to­
mat ically, other convenience and safety funct ions
are available when you start driving
<¢ page 62,

Emergency braking function
You can use the emergency braking function in an
emergency situation, or if the standard brake op­
eration malfunctions or is disabled.
.. Pull and hold the ®l switch .
.. As soon as you release the ®) switch or acceler-
ate, the braking stops.
Pulling and holding the
®l sw itch wh ile driving
the vehicle activates the emergency braking func­
tion. The vehicle is braked at all four wheels by
activating the hydraulic brake system. The brak­
ing effect is similar to heavy braking
r¢ &_ .
To reduce the risk of activating the emergency
braking by mistake, a warning tone (buzzer)
sounds when
the(®) switch is pulled. Emergency
braking stops as soon as
the(®) sw itch is released
or the accelerator pedal is pressed.
Parking
.,.. Press the brake pedal to stop the vehicle.
.. Pull the®> switch to set the parking brake .
.. Place the selector lever in the P position.
.. Turn the engine off r¢ &_ .
.. Turn the steering whe el wh en parking on in­
clines so that the wheels will roll into the curb
if the vehicle starts moving.
A WARNING
-- Do not press the accelerator pedal inadver-
tently if a gear is selected when the vehicle
is stationary and the engine is running. Oth­
erwise, the vehicle will start to move imme­
diately and this could result in an accident.
- Emergency braking should only be used in
an emergency, when the normal brake pedal
has fai led or the brake pedal is obstructed .
During emergency braking, your vehicle will
brake similar to heavy braking . ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which increases the risk of an accident .

Drivin g
- If the power sup ply fai ls, you cannot set the
parking brake if it is release d. In this case,
park the vehicle on level ground an d secure
it by placing the selector lever in the P posi­
t ion . See an authorized Aud i d ealer or au­
thorized Aud i Serv ice Facility for ass istance.
- If you leave the veh icle, switch the ignit ion
off and take the vehicle key w ith you . This
applies particularly when children remain in
the vehicle. Othe rwise children could sta rt
the engine, re lease the par king brake o r op­
erate electrical equipment such as power
windows, which increases the risk of an acci­
dent.
- No one shou ld remain in the vehicle when it
is locked - especially chi ldren . Locked doors
make it more diff icu lt for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D Tips
When stopping at a traffic signal or stopping in city traffic, you can set the parking brake
manually. The vehicle does not have to be
he ld w ith the brake pedal. The parking brake
elim inates the tendency to creep when a se­
lector lever pos ition is engaged. As soon as
you press the accelerator pedal, the park ing
brake releases automat ica lly and your vehicle
s tarts to move
~ page 62.
(D Tips
- Occasiona l noises when the par king b rake is
set and re leased a re normal and a re not a
cause for con cern.
- T he par king brake goes th ro ugh a se lf-test
cycle at regular intervals when the veh icle is
stoppe d. Any noises associated w ith this a re
no rma l.
- If there is a power fa ilure, the p arking bra ke
will not set if it is re leased, and it will not
release if it is
set~ &.. See an authorized
A udi dealer or authorized Audi Service Fa­
cility for ass istance.

vent the vehicle from ro lling back when starting.
D ur ing this time, you can easily begin to move
your vehicle.
A WARNING
Applies to: vehicles with hill hold assist
-If you do not beg in dr iving immed iate ly or
t he engine stalls after releasing the bra ke
pedal, your veh icle may beg in to roll back ­
ward . Press the bra ke peda l or set the park­
ing brake immediately.
- The inte lligent technology of hill ho ld assist
cannot ove rcome the limitat ions imposed by
natural phys ica l laws. The increased com fort
offered by hill hold assist should not cause
you to take safety risks .
- Hill hold ass ist cannot hold the vehicle in
place on all hills (for examp le, if the ground
is s lippery or icy).
- To reduce the r is k of an accident, always
