technical specifications AUDI R8 SPYDER 2014 Owners Manual

168 Fuel supply and filling your fuel tank
-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving .
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time.
(CT) Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build-up caused by
the type of gasoline you use.
A lthough gasoline grades differ from one
manufacturer to another, they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and fuel
systems clean, they are not equally effec­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your
engine of peak performance.

Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in­
structions see¢
page 170.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data <=>page 225.
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see ¢
page 167.
Your vehicle fuel tank has an on-board refuel­
ing vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
.8, WARNING
Under normal operating cond itions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must

cause ma lfunction of the tire pressure moni­
toring system, and is not recommended (cord
materia l information in molded on the tire
sidewall).
A lways check your tire pressure monitoring
system indicator after replacing one or more
tires on your vehicle . If the tire pressure mon i­
toring system indicator flashes, or is on, your
system is not working properly.
A WARNING
-Us ing incorrect or unmatched tires and/
or wheels or improper tire and wheel
combinations can lead to loss of cont rol,
co llision and serious persona l injury.
- Always use tires, rims and wheel bo lts
that meet the specifications of orig inal
factory-installed t ires or other combina­
t ions that have been specifically ap­
proved by the vehicle manufac turer .
- T ires age even if they are not be ing used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
o ld can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- Only the wheel/tire s izes specified by the
manufacturer may be used on veh icles
with all-wheel dr ive.
- Never drive faster than the maximum
speed for which the tires on your veh icle
are rated because ti res that are driven
fas ter than their rated speed can fail
sudden ly.
- Overloading t ires cause heat build-up,
sudden tire failure, incl uding a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are prope rly inflated and not over or un­
derinflated. -
For technica l reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same veh icle model.
- Do not use run-flat tires on your vehicle.
Using run-flat tires can lead to veh icle
damage or crashes .
(D Note
-For technical reasons, it is not generally
possible to use the wheel rims from oth­
er veh icles . Th is can hold true for wheels
of the same vehicle type .
- If you should put different wheels and
tires on your veh icle (e.g. winter wheels
and tires), you must be certain that the
wheels and tires are compatible with the
tire pressure monitoring system. Other­
w ise the system will register a malfunc­
tion and a fau lt message w ill be dis­
played. For more information, contact
your authorized Audi dealer.
(D Note
- When installing new tires, be care ful not
to damage the valves or tire pressure
monitoring system sensors.
- Never drive without the valve stem cap.
The va lves co uld get damaged.
- If the sensors must be replaced, then
the valve must also be replaced at the
same time.
@ For the sake of the environment
Dispose of o ld tires in accordance with the
l ocal requirements .
