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.
WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.

NOTICE
x The vehicle's diesel engine was designed solely for use with ULSD fuel. For this reason,
never use gasoline, heating oil, or other fuels that have not been expressly approved for use
with the diesel engine. These fuels contain substances that will severely damage the fuel
system and the engine. Such damage will not be covered by any Volkswagen Limited Warranty.
x If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same
applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic
part. Wash the contaminated vehicle parts right away with soap and warm water to help
prevent leaks and serious damage.
x The vehicle is designed to run on diesel fuel containing methyl ester biodiesel in
concentrations of 5% or less. Never use methyl ester biodiesel in blend levels higher than 5%
(5%/ methyl ester blends are sometimes designated or labeled as B5). The properties of methyl
ester biodiesel blends in levels greater than 5% may cause serious damage to the fuel injection
system and to the engine. This could lead to expensive repairs that will not be covered by any
Volkswagen Limited Warranty.
x Damage to the engine and fuel system and performance problems caused by using fuels
that are different from those specified above or by using “starting assist fluids” are not the
responsibility of Volkswagen and are not covered under the Emission warranties or any other
Volkswagen Limited Warranty.

Therefore we strongly recommend that you use your cellular telephone in your vehicle only when it is
properly attached to an appropriate cradle mounted on a base plate on the instrument panel.
Because of the large number and variety of cellular telephones on the market and the frequency with
which new models are introduced, Volkswagen does not offer cradles for cellular telephones. Please
check with the manufacturer of the cellular telephone that you plan to use.

WARNING
A mobile phone on the seat, instrument panel or in other places can be thrown around the
inside of the vehicle during a sudden braking maneuver, a crash or other accident and injure
vehicle occupants.
x Never place or attach accessories or other objects (such as cup holders, telephone
brackets, note pads, navigation systems, large, heavy or bulky objects) on the doors, on the
windshield, over or near the area marked “AIRBAG” on the steering wheel, instrument panel,
backrests or between these areas and the occupant. Such objects could cause serious injury
in a collision, especially if an airbag inflates.

WARNING
Using a mobile phone or CB radio inside the vehicle without a properly installed and separate
outside antenna can be dangerous to your health and that of your passengers because the
electromagnetic radiation energy that cell phones and CB radios emit may be above
established limits. This also applies if the outside antenna is not installed properly.
x Always keep the mobile phone antenna at least 8 in. (20 cm) away from pacemakers. Heart
specialists advise that cell phones can adversely affect the way pacemakers work.
x Never carry a mobile phone that is switched on in the breast pocket directly over a
pacemaker.
x If you suspect there may be interference with a pacemaker or other medical device, switch
the mobile phone off immediately.
