2017 AUDI TT ROADSTER inflation pressure

Safe driving
_& WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
- Always distribute the load as evenly as
possible .
- Place heavy objects as far forward in the luggage compartment as possible.
- Never exceed the Gross Axle Weight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceeding permissible weight
standards can cause the vehicle to slide and hand le differently .
- Please observe information on safe driving
c';> page 181.
_& 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 .
_& 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.
186 -
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.
{1) 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
c';> page 257.
Tie -downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .

A_ WARNING -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
- Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
254
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents .
-If you install wheel covers on the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Hav e an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear .

2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 256, fig. 190.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the "XXX" amount
equals 1400 lbs and there will
be five 150 lbs passengers in
your vehicle, the amount of available cargo and luggage
load capacity is 650 lbs
(1400-750 (5
X 150) = 650 lbs)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­ ceed the available cargo and luggage load capacity calculat­
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your ve-

hicle. Consult this manual to
determine how this reduces
the available cargo and lug­
gage load capacity of your vehi­
cle.
~check the tire sidewall
(¢ page 246, fig. 188) to deter­
mine the designated load rating
for a specific tire.
· Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them
¢ &..
_8. WARNING
-Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
¢ page 2 78, Finishing.
- Always keep the wheel bolts and the threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident .

Traction
The traction grades, from highest to lowest, are
AA, A, B and
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
¢ _& .
Temperature
The temperature grades are A (the highest), B ,
and
C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
c:> .& .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard No.
109 . Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight -ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded . Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Wheels
Tire pressure monitoring system
ill General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size ind icated on
the vehicle placard or tire inflation pressure la­ bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant ­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure . Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure, even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly . The TPMS mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the .,.
