restraints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploying prop­
erly.
- Never use cushions, pillows, blankets or
similar items on the front passenger
seat. The add itional padd ing will prevent
the weight-sens ing mat in the seat from
accurately reg istering the ch ild restra int
or person on the seat and preve nt the
Advanced Airbag System from func tion­
ing properly .
- If you must use a child restra int on the
front passenger seat and the ch ild re­
straint manufacturer's instructions re­
quire the use of a towel, foam cush ion or
something else to properly position the
child restraint, make certa in that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
st ra int is installed on the front passen­
ger seat .
- If the
PAS SENGER AIR BAG OFF light
does not come on and stay on, have the
airbag system inspected by your Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side airbags s upplement the protection of­
fered by the front three-point safety be lts
with pretensioners and load limiters and the
adjustab le head restra ints to he lp reduce the
risk of injury in a wide range of acc ident and
crash situat ions . Be sure to read the impor­
tant information about safety and heed the
WARNINGS i n this chapter .
Deployment of the Advanced Airbag System
and the act ivat ion of the safety be lt preten­
sioners depend on the dece le rat ion measured
by the c rash sensors and registered by the
e lectronic control un it . Crash severity depends
on speed and dece leration as well as the mass
and stiffness of the vehicle or object involved in the crash .
Airbag system 117
When the electronic control unit registers a
low severity cras h and the safety belt is being
used, the airbag will not dep loy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat­ er t ime in the crash sequence.
If the electron ic control unit registers a crash
of medium severity, the first stage of the air­ bag deploys followed by the second stage at a
much later time in the crash sequence -re ­
gardless of whether the safety belt is be ing
used or not . In higher sever ity crashes as reg­
iste red by the elect roni c cont rol unit, bot h the
first and se cond s tages deploy almost at the
same t ime.
On the passenger side, regardless of safety
belt use, the airbag w ill be tu rned off if the
weight on the passenger sea t is less than the
amount programmed in the electronic control
u nit . The front airbag on the passenger side
will a lso be turned off if one of the child safe­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recognized on the seat. The
PASS ENGER A IR
BAG OFF light comes on and stays on to te ll
you when the front Adva nced A irbag on the
passenger side has been turned off

_&. WARNING ~
To reduce the risk of inj ury when an a irbag
inflates, always wear safety be lts properly.
- If you are unrestrained, leaning forward,
sitting sideways or o ut o f position in any
way, your risk of injury is m uch higher.
- You will a lso receive serious injur ies and
could even be killed if yo u are up against
the airbag or too close to it when it in­
f lates -even with an Advanced A irbag

stra int be lt path
c:> ,&. .
., Push the child safety seat down with your
full weight to get the safety belt rea lly t ight.
., In sert the be lt tongue into the buckle fo r
t h at seating posi tion.
., Gu ide the safety be lt back into the retracto r
u nt il the belt lies flat a nd snug on the chi ld
sa fe ty seat.
., You should hear a "clicking" noise as the
belt winds bac k into the ine rtia reel. Test the
conve rtible locking retractor by pull ing on
the be lt . You should no longer be able to
pull the belt out of the retractor. The con­
vertib le lock ing retractor is now act ivated. .,
Ma ke s ure that the red release button is fac ­
ing away from the child rest raint so that it
can be unbuckled q uick ly .
., Pull on the belt to make sure the safety be lt
is properly tight and fastened so that the
seat ca nnot move forward or sideways more
t han one inch (2.5 cm) .
A WARNING
Using the wrong child res traint o r an i m­
pr operly ins talled chi ld restraint can cause
se rious pe rsonal injury or death in a crash.
- Always ma ke sure that the safety belt re-
trac to r i s lo cked when insta lling a child
safety seat . An un locked safety bel t re­
tracto r cannot hold the child safety seat
in place dur ing no rma l dr iving o r in a
crash.
- Always buckle the child safety seat firmly
in place even if a ch ild is not sitt ing in it.
A loose child safety seat can fly around
during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright pos ition. Otherw ise, the seat­
back with the ch ild safety seat attached
to it could fly forward in the event of an
accident o r othe r emergency situation.
- Always read and heed all WAR NIN GS

gear or lower driving range. Do no t ride
t h e brakes or hold the pedal down too
long or too often. This cou ld cause the
bra kes to get hot and dimin ish braking
efficiency .
- Do no t "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the brakes to
overheat, prematu re wear and inc reased
stopp ing distan ce.
- Under certain climat ic and operating
c ondit ions such as passing through wa­
ter, driving i n heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be red uced . In winter, ice can
accumulate on the brake pads, linings,
discs and d rums . Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake d iscs and pads w it h a few cautious
brake appli cat ions.
- If you damage the fro nt spo iler, or if you
ins tall a different spoiler, be su re the air
flow to the fron t bra kes is not o bstr uct­
ed. O therwise the brake system co uld
overheat reducing the effectiveness of
the entire brake system.
- F ailure o f one bra ke c ircuit will impair
the b raking capability resulting in an in­
creased stopp ing distance . Avoid driv ing
the vehicle and have it towed to the near­
est Aud i dea le r o r qualified workshop.
- Never let the vehicle ro ll to a stop w ith
the engine shut off.
- If the brake booster is not working, t he
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance . Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assi st is electronically
matched to vehicle speed .
T he power steering system assists the driver
so that he can steer the vehicle with reduced
physical effor t.
Power steering will not work if t he engine is
off . As a result, the steering wheel will be hard
to turn.
A WARNING
If the system develops a problem , you
must seek qualified profess iona l assis ­
tance .
(D Note
-
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onge r proportionate to the vehicle speed .
This is most not icea ble whe n tu rni ng the
s tee ring w heel a t low speeds (fo r example
when pa rking), -more effort w ill be re­
q uired than us ua l.
- Be aware o f the diffe rent than usual
steering response and adjust your steer ­
ing force acco rdingly.
- Have the problem checked and set right
by an autho rize d Aud i dealer as soon as
possible.
- If a s teer ing mal func tion occurs, this is
signa led wit h the
,'Zr~ or .• indicato r
lights and a warning tone, see.
(D Tips
- If the powe r stee ring system sho uld fai l,
or if the engine is not ru nning (fo r exam­
ple, whi le being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.

Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
T his is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any higher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv ­
ing through it.
- Do not s top the veh icle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh sa lt water because
it can cause corrosion.

Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.,. Always use lead-free gasoline¢ page 161 ,
Fuel supply.
.,. Never run the tank down all the way to emp­
ty.
.,. Never put too much motor o il in your engine
c:::> page 170, Adding engine oil 9::71 .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalytic converter is an efficient "clean­
up" dev ice built into the exhaust system of
the vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be­
f ore they are re leased into the atmosphere .
T he exclusive use of unleaded fuel is critically
important for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine .
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other materia l wh ich can
cause a fire .
- Do not apply additional undercoating or
rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. Dur ing driving, the
substance used for undercoating could
overheat and cause a fire .
(I) Note
-Be aware that just one tank filling with
leaded fuel w ill already ser iously de­
grade the performance of the catalytic
converte r.
- Do not exceed the correct eng ine oil level
c:::> page 170.
- Do not drive until the fue l tank becomes
completely empty . The engine could m is-
fire. Unburned fuel could also get into

154 Driving and environment
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold eng ine.
The engine and catalyt ic converte r have to
reac h their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effect ively .
- Just after starting, a co ld engine in a m id­
s iz e car burns the fuel at a poor rate of 6-8
miles per gallon (30-40 l/l00km). Half a
mile dow n the road, the m ileage imp roves
to 12 M PG (20 l/100 km) . It will take t he
engi ne no less than
two and a half mil es
(4 km) of driving to warm up to its prope r
oper ating tempe ra tur e and ope rate at an
e conomi c mileage. This explains w hy taking
t h e car for s hort tr ips is a rat her wastef ul
co nvenience.
- T he
outside temperature is also cr itica l in
t h is regard. Yo ur car consumes more fuel in
t h e winter than in t he summer .
Trailer towing
General information
Your Audi TT Roadster is not designed to tow
a trailer .
Towing a tra iler with yo ur Audi n Roadster is
n ot recommended and can ca use damage to
the car . Damaged caused by towing a t railer is

190 Tires and wheels
Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be overloaded.
Steps for Determining
Correct Load Lim it
1 . Locate the statement "THE
COMB INED W EIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi ­
cle's placard (tire inflation
pressure label) ¢
page 185,
fig. 138.
2.
Determ ine the comb ined
weight of the driver and pas ­
sengers that will be riding in
your vehicle .
3. Subtract the combined weight of the dr iver and pas­
sengers from
"XXX " kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 185, fig . 138 .
4. The resulting figure equals
the available amount of car­go and luggage load capaci­
ty . F or examp le, if the "XXX"
amount equals 1400 lbs. and there will be five 150
lbs . passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­ pacity is 650 lbs . (1400 -750
(5
X 150) = 650 lbs .)
5 . D etermine the combined
weight of luggage and cargo be ing loaded on the vehicle.
That we ight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step
4 .
6. If your vehicle will be towing
a trailer, load from your trail ­
er will be transferred to your
vehicle . Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehic le .
... Chec k the tire sidewall
(¢ page 192, fig. 142) to de­
termine the designated load rating for a specific tire .
