heavy engine load. Otherwise, the engine could be damaged. Refuel your vehicle with gasoline
with the required octane rating as soon as possible.
x
Do not use fuel that is labeled at the pump as containing metal. Lead replacement fuel
contains high concentrations of metallic additives. Engine damage could result.
x
Fueling your vehicle just one time with leaded fuel or fuel that contains other metallic
additives can affect the performance of the catalytic converter and cause extensive damage to
it.
Diesel fuel
¤
Please first read and note the introductory information and heed the WARNINGS
Always use only Ultra Low Sulfur Diesel (ULSD) fuel No. 2
⇒
.
The ULSD must always meet ASTM D-975 specification
⇒
.
“ULSD” should be clearly marked on the pump. Before filling your vehicle, please always make sure
you are using ULSD. According to Federal regulations ULSD is the only diesel fuel type allowed for
use in your vehicle.
Using diesel fuel with concentrations of methyl ester biodiesel higher than 5 % (B5), such as B11, B20,
or B100 when B5 biodiesel is available, is contrary to the terms of your New Vehicle Limited Warranty
and is strictly prohibited.
ULSD diesel fuel may not be available outside the USA and Canada. Be sure to check availability
before traveling to other countries.
Winter diesel
At temperatures below 20 °F (-7 °C), wax separation in ULSD occurs. Wax may clog the fuel filter or
tank filter and keep the engine from running.
To help prevent the filter from being clogged with wax, the fuel filter in your vehicle is heated with
warm fuel when the engine is running (filter preheating system). Heating the fuel filter makes it
possible to use your vehicle with ULSD down to about -10 °F (-24 °C).
If you expect temperatures below +5 °F (-15 °C) ask your fuel dealer if their ULSD is sufficiently
winterized.
If non-winterized or insufficiently winterized diesel fuel has already thickened to the point that the
engine will not start, move the vehicle to a heated garage or workshop until it has warmed up.
Cold diesel engines normally produce louder noises during winter conditions than during warmer
periods. In addition, the exhaust gases may be light blue in color until the engine has warmed up. The
exhaust gas volume varies depending on the outside temperature.
Do not let your diesel engine idle unnecessarily after a cold start. Driving off slowly will shorten the
warm-up period.
Illinois registered vehicles
Biodiesel is a domestically produced, clean-burning and renewable partial substitute for conventional
(petroleum) diesel fuel.
Your vehicle was originally designed to run on “ULSD” – Ultra Low Sulfur Diesel fuel [ASTM D-975
standard Grade No. 2-D (S15)] that complies with ASTM D-975 specifications and permits up to a
maximum blend of 5 % biodiesel (B5).
Due to Illinois state tax incentives or regulations for biofuels, biodiesel blends of B5 or less may not be
available in Illinois.
However, we want to assure you that Volkswagen will continue to honor the terms
and conditions of the Volkswagen Limited Warranties that came with your vehicle.
Use only Biodiesel
from high quality sources, certified by the BQ-9000 label at the fuel station and complying to ASTM D
7467 S15, B6 to B20.
