2013 VOLKSWAGEN TOUAREG ad blue

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 bio diesel in
concentrations of 5% or less. Never use methyl ester bio diesel in blend levels higher than 5%
(5% methyl ester blends are sometimes designated or labeled as B5). The properties of methyl
ester bio diesel 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.

Failure to heed warning lights or text WARNINGS can result in vehicle damage.
AdBlue information
.

In vehicles with selective catalytic reduction, a special urea solution (AdBlue) is injected into the
exhaust system ahead of the catalytic converter in order to reduce nitrogen oxide emissions.
AdBlue is stored in a separate tank of the vehicle and should be refilled under normal driving
conditions during service according to the maintenance schedule. The AdBlue tank holds slightly less
than 5 gallons (20 liters).
AdBlue consumption depends on the individual driving style, system operating temperature, and
outside air temperature. Therefore in rare cases AdBlue may have to be refilled between service
events.
Starting with a remaining range of about 1500 miles (2400 km), a reminder to refill AdBlue is displayed
in the instrument cluster. If you ignore the last refill reminder, it is impossible to start the engine again
after it is switched off
Volkswagen recommends that you have the AdBlue tank refilled by an authorized Volkswagen dealer
or an authorized Volkswagen Service Facility. If no authorized Volkswagen dealer or authorized
Volkswagen Service Facility or other qualified workshop is available, you should refill at least 1.5
gallons (5.7 liters) of AdBlue (3 AdBlue bottles). Refill only the type of AdBlue that Volkswagen has
explicitly approved for your vehicle.
If warning lights ~ and d both come on together, there is a malfunction. Volkswagen recommends that
you take the vehicle to the closest qualified workshop.
AdBlue® is a registered trademark of the German Association of the Automotive Industry (VDA) in the
United States, Germany, the European Union and in other countries.

.WARNING
Store AdBlue only in its closed original container and in a safe place.
x To reduce the risk of poisoning, never keep AdBlue in empty food or beverage containers
that might mislead someone into drinking from them.
x Always store AdBlue outside the reach of children.
.NOTICE
x Use only AdBlue that has been explicitly approved by Volkswagen. Using other types of
AdBlue can damage your vehicle's engine.
x Never mix water or any other substances or additives with AdBlue. Damage caused by such
additives will not be covered by any Volkswagen Limited Warranty.
x Never put AdBlue into the diesel fuel tank! Otherwise the engine may be damaged!
x Do not CARry a refill container in the vehicle all the time or routinely. Due to temperature
fluctuations and damage, the container could start leaking and the AdBlue could damage the
vehicle interior.
.Dispose of the refill container in an environmentally-responsible manner.
.Appropriate AdBlue refill containers can be obtained from an authorized Volkswagen dealer or
an authorized Volkswagen Service Facility.
