@ Tips
It may take longer to start the engine
when the outside temperature is very cold.
If possible, use winterized fuel if tempera­
tures are below freezing.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use.
Although 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.
Aud i recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIE R
Detergent Gasoline, please go to the officia l
website (www.toptiergas .com) .
Afte r an extended pe riod of using inadequate
fuels, built-up carbon deposits can rob your
engine of peak performance.
CD Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Warranty.
- Do not add aftermarket fuel additive
products to your fuel tank.

Fuel supply and filling your fuel tank 209
The label on the inside of the fuel fi lier f lap
te lls you the correct fue l for your vehicle. For
more information about fuel specifications,
see
c:> page 207.
Your vehicle fue l tank has an on -board refue l­
ling 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
proper ly while protecting the environment,
please follow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, fu ll or empty, may leak and could
cause a fire in a collision. If you must
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 - 86).
CD Note
Never drive your veh icle until the fuel tank
i s completely empty. The irregu la r supply
of fue l can cause misfiring. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.
