2011 AUDI TT ROADSTER ECU

Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat
or any other object.
Make sure that all pedals move freely without
interference and that nothing prevents them
from returning to their original positions .
Only use floor mats that leave the peda l area
free and can be secured with floor mat fasten­
ers .
If a brake circuit fails, increased brake peda l
travel is required to bring the vehicle to a full
stop.
A WARNING
Pedals that cannot move freely can cause
loss of vehicle control and increase the r isk
of serious injury.
- Never place any objects in the driver's
footwell. An object could get into the
peda l area and interfere w ith pedal func­
tion. In case of sudden braking or an ac­
cident, you would not be able to brake or
accelerate!
- Always make sure that nothing can fall
or move into the driver's footwell.
Floor mats on the driver side
Always use floor mats that can be securely
attached to the floor mat fasteners and do
not interfere with the free movement of the
pedals.
"' Make sure that the floor mats are properly
secured and cannot move and interfere with
the pedals ~
A,.
Use only floor mats that leave the pedal a rea
unobstructed and that are firmly secured so
that they cannot s lip out of position. Yo u can
obtain suitable floor mats from your author­
ized Audi Dealer.
Floor mat fasteners are installed in your Audi .
Driving S afel y 103
Floor mats used in your vehicle must be at­
tached to these fasteners . Properly securing
the f loor mats will prevent them from sliding
into positions that could interfere with the
pedals or impair safe operat ion of your vehicle
in other ways.
A WARNING
Pedals that cannot move freely can result
in a loss of vehicle control and increase the
risk of serious persona l injury.
- Always make sure that floor mats are
properly secured.
- Never p lace or install floor mats or other
f loor coverings in the vehicle that cannot
be properly secured in place to prevent
them from slipping and interfer ing with
the peda ls or the ab ility to contro l the
vehicle .
- Never place or install floor mats or other
floor coverings on top o f already instal­
led floor mats . Additiona l floor mats and
other coverings will reduce the size of
the peda l area and interfere with the
pedals.
- Always properly reinstall and secure floor
mats that have been taken out for clean­
ing.
- Always make sure that objects cannot
fall into the dr iver footwell while the ve­
hicle is moving . Objects can become
trapped under the brake pedal and accel­
erator pedal causing a loss of vehicle
control.
Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­ erly stowed and secured in the luggage com­
partment.
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling
characteristics. Loose items can a lso increase
the risk of serious persona l injury in a sudden
vehicle maneuver or in a collision. •

104 Driving Safely
• Distribute the load evenly in the luggage
compartment.
• Always place and properly secure heavy
items in the luggage compartment as far
forward as possible.
A WARNING
Improperly stored luggage or other items
can fly through the vehicle causing serious
personal injury in the event of hard brak­
ing or an accident. To help reduce the risk
of serious personal injury:
- Always put objects, for example, luggage
or other heavy items in the luggage com­
partment.
- Always secure objects in the luggage
compartment using the tie-down eyelets
and suitable straps.
A WARNING
Heavy loads will influence the way your ve­
hicle 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 cen­
ter 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 Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­
missible weight standards can cause the
vehicle to slide and handle differently.
- Please observe information on safe driv­ ing
~ page 98.
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 because 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
panel,
- 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 es­ pecially with the rear lid left open . A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
@ Tips
- Air circulation helps to reduce window
fogging. 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 la­ bel is located on the driver's side B-pillar .

from the battery and drain it, for example, the
engine immobilizer . To prevent this, you can
e ither charge the battery occasionally to keep
it in good working condi tion or you can d is­
connect the negat ive cable on the battery .
Winter ope ration
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
start ing, and the headlights, rear window de­
fogger, etc ., are used more often .
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when traveling on ly
short distances. Let your authori zed Audi
dealer check the capacity of the vehicle bat ­
tery before winter sets in
¢ page 192. A well
charged battery w ill not only prevent starting
p rob lems when the weathe r is cold, but will
a lso last longer .
Replacing b attery
The new battery m ust have the same capaci ­
ty, voltage (12 volts), amperage, construction
a n d p lug sealing, as the origina l batte ry. Spec­
ifications are listed on the batte ry housing.
Batteries specially developed by A udi f ulfill
the ma intenance, output, and safety require ­
ments.
When insta lling the bat tery , make sure the ig­
n ition and all e lectr ica l cons umers are sw itch­
ed

We recommend that you use ma intenance­
free or
cy cle-re sis tant /le ak -proof batteries
according to the standards TL 825 06 (from
December 1997) and VW 7 SO 73 (from Au ­
gust 200 1).
Replacing the battery should be ca rried by a
qua lified workshop. Please follow the instruc­
tions on the battery cover.
(D Note
- All work on t he battery requires techni­
ca l knowledge. Please contact an A udi
dealership or anothe r authorized facili ty
Checkin g and fillin g 189
for questions abo ut the batte ry - danger
of acid burns and exp losion hazard!
- T he battery must not be opened! Do not
try to change the battery's liquid level,
otherwise detonating gas will escape
from the battery - explosion hazard!
- The AGM battery in the luggage com­
partment cannot leak, because the elec ­
tro lyte for this battery is absorbed into a
special glass mat. This leak-proof battery
must not be replace with a convent iona l
battery.
- Make sure the ventilation hose on the
side of the battery is connected, other­
w ise fumes or battery ac id can leak out.
- Battery holder and terminals always
have to be secured correctly.
- Before all work on the battery follow the
warnings below ¢.&. in Working on the
battery on page 190.
@) For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recommend your author ­
ized Audi dealer change the battery for
you. Batteries contain sulfur ic acid and
l ead and must always be disposed of prop­
erly in compl iance with a ll environmental
regulat ions. Disposing of vehi cle batter ies
improperly is very dangerous to the envi ­
ronment. Make sure that the removed bat­
tery cannot overbalance, otherwise sulfu­ ric acid might escape!
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery shou ld be removed and
stored where it w ill not freeze. This will
prevent it from be ing damaged and having
to be replaced . •
