warning lights AUDI TT ROADSTER 2017 Owner's Manual

Driving
Avoid full acc ele ra tion
You sho uld rare ly travel at the maximum vehicle
speed . High speeds cause a disp roportionately
high increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the engi ne, for examp le when
at rai lro ad crossings or tr affic lights with longer
red lights . Stopping the engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to resta rt the engine.
It t akes a very long time in idle to wa rm the en­
g ine up to operating tempe ra ture . Wear and
emissions are especially high in the warm-up
p hase . Therefore, yo u should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Have ma intenanc e performed r egularly
By having maintenance performed regular ly on
your vehicle, yo u can help to reduce f uel con­
sumpt ion before you even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l­
so impacts
fuel consumpt ion .
A poorly maintained engine can lead to fuel con­
sumpt ion that is 10% higher than normal.
A lso check the
oil le vel when refueling . The o il
consumption
depends large ly on the engine load
and speed. It is normal for the oil consumpt ion
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can o nly be properly judged after
approx imately 3,000 m i (S,000 km) have been
d riven.
Avoid short trips
The engine and exhaust cleaning system must
reach the ir opt imal
operating temperature to ef­
fectively red uce consumption and em iss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The engine reaches operating
temperature and consumpt io n normalizes only
afte r approximately
four kilometers.

(D Note
Do not leave engine idling unattended after
starting. If warning lights sho uld come on to
i ndicate imprope r operation, they would go
unheeded. Extended idling also produces
h eat, which could result in overheating or
other damage to the vehicle o r other proper­
ty.
(D Note
- Have your ve hicle ma intained properly and
in accordance with the service recommenda­
t ions i n your Warranty
& M aintenance book­
let. La ck of prope r mai nte na nce as we ll as
imp roper use o f the ve hicle will impa ir the
func tion of the emission cont ro l sys tem and
cou ld lead to damage.
- Do not alte r or remove any compone nt of
the Emission Contro l System unless ap ­
proved by the man ufacturer.
- Do not alte r or remove any dev ice, such as
heat shields, switches, ig nition w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
important veh icle components.
(D Tips
The cons umption estimates as publishe d by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the r oad, which wi ll vary depending upon vehicle
l oad and speed, road a nd wea ther conditions,
tr ip length, etc.

Driving
-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.
(D 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
¢ page 59, fig. 67.
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
! START ENGINE STOPI button twice in a row
briefly or press and hold for longer than two sec­
onds.
_&. WARNING
- Never turn off the engine before the vehicle
has come to a complete stop.
60
- 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.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after th@ 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.

snow and ice. Always read and follow safety pre­
cautions
¢ & .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 261, Snow chains.
Replacing tires
For vehicles with all wheel drive, only whee ls with
the same rolling circumference should be used .
Avoid using tires with different tread depths
¢ page 2 53, New tires or wheels.
Offroad vehicle?
Your Aud i is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.
_&. WARNING
-Also, in vehicles with all wheel drive, adapt
your driv ing style to the current road and
t ra ffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the r isk of an acci­
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev highe r sud­
denly when the vehicle begins hydroplaning.
For this reason, pay attention to the road
conditions regardless o f your speed.

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are neces­
sary, how they work and how to adjust and wear
them correctly. .. Read all the information that follows and heed
all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death .
- Safety belts are the single most effective
means available to reduce the risk of serious
injury and death in automobile accidents.
For your protection and that of your passen­
gers, always correctly wear safety belts
when the vehicle is moving.
- Pregnant women, injured, or physically im­
paired persons must also use safety belts.
Like all vehicle occupants, they are more
likely to be seriously injured if they do not
wear safety belts. The best way to protect a
fetus is to protect the mother -throughout
the entire pregnancy.
Number of seats
Your Audi TT Roadster has two seating positions. Each seating position has a safety belt .
A WARNING

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine .
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.
(D Tips
I f you need to add oil and there is none availa­
ble t hat meets the Audi o il quality standard
your eng ine requi res , you m ay ad d a tot al of
no more than 0.5 q t (0,5
l) of a h igh-quali ty
"synthe tic"oil that meets t he following speci ­
fications.
- AC EA A3 o r API SM wi th a viscosity grade o f
SAE 0W-30, SAE 5W-30 or SAE 5W-40.
- F or more inform ation about engine o il that
has been approve d for your ve hicl e, please

or A udi C ustome r Relat ions at
1 (800) 822-2834 or visit o ur web site at
www.audiusa.com or www.audicanada.ca .
Engine oil consumption
T he engine in your vehicle depends on an ade­
quate amoun t of oil to lubricate and cool all of
i ts moving par ts.
In order to p rovide effective lubr ication and cool­
ing of internal engine components, all interna l
combustion engines consume a cer tain amount
of oil. Oi l co nsumption varies from engine to en ­
g ine and may change significant ly over the life of
the eng ine . Typically, eng ines with a specified
238
b reak -in period (see q page 57) cons ume more
oi l during the break-in period than they consume
after o il consumption has stab ilized.
U nder normal cond itions, the ra te of oil con ­
