2018 AUDI TT ROADSTER air condition

Intelligent Technology
Wear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently
in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Wet conditions or road salt
I n certain situations, for example after dr iving
through water, in heavy ra in or after washing
your car, the braking effect may be reduced due
to moisture or ice on the brake rotors and brake
pads . The brakes must be "dried" first with a few
careful brake applications.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake
rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking effect can also be reduced if you are
driving on sa lted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
h igh speeds is recommended to clean the brake
rotors and
pads¢ &.
Brake system malfunction
If you notice that the brake pedal travel has sud ­
denly increased, then a brake circuit in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Aud i dea ler or authorized
Aud i Serv ice Facility immediately to have the
88
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake pedal harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
t h e brake system may occur . The brake fluid leve l
is electronically monitored .
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
& WARNING
- New brake pads do not achieve their full
braking effect during the first 250 mi
-
(400 km). They must be "broken in" first .
However, you can compensate for the
slightly reduced braking force by pressing
firm ly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- On ly app ly the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users . This increases the
r is k of an accident.
- On steep slopes, reduce the speed and se­
lect a lower gea r or lower selector leve r po­
sition. Drive as lit tl e as possible while press­
ing the brake pedal and avo id putting yo ur
left foot on the brake pedal while driv ing .
This could ca use the brakes to overheat and
impair the efficiency of th e brakes.
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces­
sarily.
- Certain weather and operating conditions such as driving through water, dr iv in g in
heavy rain or driv ing after wash ing your ve­
h icle can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these compon ents by braking carefully. Ap­
plying the brakes carefully several times
dries the brakes and removes ice build-up.

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
-The efficiency of the brakes can also be im­
paired by driving for long stretches on roads
covered with salt without using the brakes .
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes severa l t imes .
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are vent ilated proper ly . Otherwise,
the b rake system could overheat, w hich re­
duces the ir effectiveness.
- Failure of a brake c ircuit impa irs b raking
perfo rman ce , which increases brak ing dis ­
tan ce. Avoid d riving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while t he engine is
stopped because this increases the risk of an
accident.
- If the brake booster is not working, you will
have to press much harder on the brake
peda l to compensate for the lack of the
booster.
@ Note
- Never let the brakes "rub" by pressing the
pedal light ly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking d istance and
causes wear.
- Before driving downhi ll a long distance on a
steep h ill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and relieves the brakes . If
you need to brake additionally, brake in in­
tervals and not conti nuous ly .
0) Tips
- If the brake booster is not working, you
must press the brake pedal with much more
fo rce t han normal.
- If you retrofit your vehicle with a front spoil­
er, whee l covers o r similar items, make sure
t h at the a ir flow to the front whee ls is not
i nte rru pted. Ot herw ise the brake system
ca n become too ho t.

What impairs driving safety?
Safe driving is dire ctly related to the condition of
the vehicle, the driver as well as the driver's abili­
ty to concentrate on the road without being dis ­
tracted.
T he dr iver is responsib le for the sa fe ty of the ve ­
hicle and a ll of its occupants. If your ability to
drive is impai red, safety risks for everybody in the
vehicl e inc rease and you a lso become a hazard to
everyone else on the road
¢ A_ . Therefore:
.. Do not let yourse lf be distracted by passenge r
or by using a ce llular telephone .
.. NEVER drive when your driving ability is im ­
pa ired (by med ications, alcohol, drugs, etc.) .
.. Observe all traffic laws, rules of the road and
speed lim its and plain common sense .
.. ALWAYS adjust your speed to road, traffic and
weather conditions .

A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­ cause the rear lid cannot be fully closed .
- If you absolutely must drive with the rear lid open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the convertible top,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed .
A WARNING
.
-
Always make sure that the doors, all win­
dows, the convertible top and the rear lid are
securely closed and locked to reduce the risk
of injury when the vehicle is not being used.
- After closing the rear lid , always make sure
that it is properly closed and locked.
- Never leave your vehicle unattended espe­
cially with the rear lid left open . A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.

@ Tips
- Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions , please see chap­
ter ¢page255.
Tie -downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items.

In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury. Items in the vehicle possess energy which
vary with vehicle speed and the weight of the
item . Vehicle speed is the most significant factor.
For example , in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 lbs
(4.5 kg) object are about 20 times the normal
weight of the item. This means that the weight
of the item would suddenly be about

Airbag system
The PASSENGER AIR BAG OFF~; light in the
headliner tells you when the front Advanced Air­
bag on the passenger side has been turned off by
the electronic control unit.
E ach time you turn on the ignition, the
PASSEN­
GER AIR BAG OFF
"1; ON@ light will come on
for a few seconds and:
- PASSENGER AIR BAG OFF ~; will come on if
the front passenger seat is not occupied,
-PASSENGER AIR BAG OFF ~; will come on if
t h e e lectrica l capacitance measured by the ca­
pacitive passenger detection system for the
front passenger seat equa ls the combined ca ­
pacitance of an infant up to about one year of
age and one of the rearward-facing or forward­
facing child restraints listed in Federal Motor
Vehicle Safety Standard 208 w ith which the Ad­
vanced Airbag System in your vehicle was certi­
fied. For a listing of the ch ild restraints that
were used to cert ify your vehicle 's compliance
with the U.S. Safety Standard
¢page 218.
- PASSENGER AIR BAG OFF~; will come on if
there is a small child or ch ild rest raint on the
front passenger seat,
-PASSENGER AIR BAG ON @w ill go off if the
front passenger seat is occupied by an adult as
registered by the capacitive passenger detec­
tion system ¢
page 205, Monitoring the Ad­
vanced Airbag System .
The PASSENGER AIR BAG OFF~; light comes on
when electrical capacitance registered on t he
front passenger seat is equa l to or less than the
combined capacitance of a typica l 1 year -o ld in­
fant and one of the rearward-facing or forward ­
facing ch ild restraints listed in Federal Motor Ve­
h icle Safety Standard 208 with wh ich the Ad­
vanced A irbag System in your vehicle was cert i­
f ie d.
If the tota l electrical capac itance registered on
the front passenger seat is more than that of a
typical 1 year-old child but less than the we ight
of a small adult, the front a irbag on the passen­
ge r side ca n deploy (the
PASSENGER AIR BAG
OFF
"1; light does not come on).
If the
PASSENGER AIR BAG OFF "1; light does
not come on, the front a irbag on the passenger
196
side has not been turned off by the electronic
contro l unit and can deploy if the contro l unit
senses an impact that meets the conditions stor­
ed in its memory.
For example , the airbag may deploy
if:
-a small c hild that is heav ier than a typica l 1
year-old child is on the front passenger seat
(regard less of whethe r the child is in one of the
child sa fety seats listed ¢
page 218), or
- a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger a irbag is turned off, the
PASSENGER AIR BAG OFF~; light comes on in
the headliner and stays on.
If the front passenger airbag deploys, the Feder­
al Standard requires the airbag to meet the "low
r isk" dep loyment cr iteria to reduce the r isk of in­
jury through interaction w ith the airbag. "Low
risk" deployment occurs in those crashes that
take place at lower decelerations as defined in
the e lectronic contro l unit ¢
page 206, PASSEN­
GER AIR BAG
OFF~; ON~ light.
A lways remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's airbag in a frontal col lision. The air­
bag could great ly reduce the effectiveness of the
c hi ld restraint and even ser iously injure the child
during inflat io n.
A WARNING
A child in a rearward-facing child seat instal­
led on the front passenger seat will be seri­
ously injured and can be killed if the front air­
bag inflates
-even with an Advanced Airbag
System.
- The inflat ing airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
- Forward-facing child seats installed on the
front passenger's seat may interfere with
the deployment of the airbag and cause se­
r ious personal injury to the ch ild.

seat backrests; never place them between
these areas and you or any other person in
the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music
players. Such objects could cause serious in ­
jury in a collision, especially when the air­ bags inflate .
A WARNING
A person on the front passenger seat, espe­
cially infants and small children, will receive
serious injuries and can even be killed by be­
ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
-
your vehicle is designed to turn off the front
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in accordance with the "low risk" option under
the U .S . Federal Standard if a child that is
heavier than the typical one-year old child is
on the front passenger seat and the other
conditions for airbag deployment are met.
- For its own safety, a child should always ride
properly restrained for its age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driv er's and front passenger's heads and
upper bodies in frontal crashes . The airbags in­
flate only in frontal impacts when the vehicle de­
celeration is high enough.
Airbag system
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety
belts. Rather, it is part of the overall occupant re­
straint system in your vehicle. Always remember
that the airb ag system can only help to protect
you, if you are sitting upright, wearing your safe­
ty belt and wearing it properly . This is why you
and your passengers must always be properly re­
strained, not just because the law requires you to
be.
The Advanced Airbag System in your vehicle has
been certified to meet the "low risk" require­
ments for 3 and 6 year-old children on the pas­
senger side and very small adults on the driver
side. The low risk deployment criteria are intend­
ed to help reduce the risk of injury through inter­
action with the front airbag that can occur, for
example, by being too close to the steering wheel
and instrument p anel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements of
the Safety Standard, to turn off the front airbag
for infants 12 months old and younger who are
res trained on the front passenger seat in child re­
straints that are listed in the Standard
~page 218, Child restraints and Advanced front
airbag system .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is restrained
on the front passenger seat in one of the rear­
facing or forward-facing infant restraints listed in Federal Motor Vehicle Safety Standard 208
with which the Advanced Airbag System in your
vehicle was certified . For a listing of the child
restraints that were used to certify your vehi­
cle's compliance with the US Safety Standard
~page 218,
- When a person is detected on the front passen­
ger seat that has an electrical capacitance that
is more than the total electrical capacitance of
a child that is about 1 year old restrained in one
of the rear-facing or forward-facing infant re­
straints (listed in Federal Motor Vehicle Safety
Standard 208 with which the Advanced Airbag
System in your vehicle was certified), the front
