220 Fuel supply and filling your fuel tank
Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fue l filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No. 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter. It is also norma l when whitish-blue
smoke comes out of the tailpipe after starting
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine idle unnecessari ­
ly after a cold start. Driving off slowly will
shorten the warm-up period.
A WARNING
- Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in ser ious engine damage and per­
sonal injur y.
- Never use fuel line anti-freeze offered for
gasoline engines.
(D Note
- Your Diesel engine has been specifically designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasoline. The
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
cause expensive engine repairs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel sho uld get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not allow D iesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.

Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system shou ld fail, you
can still open the flap manua lly -for detailed

¢ page 223.
You can find the fuel tank capacity of your ve­

The label on the inside of the fuel filler flap
te lls you the correct fuel for your vehicle. For
more information about fuel specifications,
see
¢ page 218.
Your vehicle fuel tank has an on board refuel­
ling vapo r recovery system. This feature helps
to prevent fue l vapors from escaping from the
tank and polluting the environment while you refuel your vehicle. In order to fi ll the tank

please fo llow this refueling procedure careful­
ly.
A WARNING
-Under normal operating conditions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other conta iners 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
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al ­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the ..,.

General information
App lies to vehicles: wi th diesel eng ine
On vehicles with se lective cata lytic reduc tion,
an urea solution (Ad Blue) is injected into the
exha ust system before a nitrogen oxide cata­
lytic converter to reduce n itrogen emissions.
The Ad Blue is s tored in a separate tank in the
vehicle. The Ad Blue usage accounts for ap­
proximately 0.5% to 1.2% of the diesel fue l
that is used.
You must refill the Ad Blue or have it refi lled
by your authorized Audi dea ler or q ua lified
workshop as soon as the Ad Blue refill mes­
sage appears in the instrument cluster
