AdBlue information

ꢀPlease first read and note the introductory information and heed the WARNINGS

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 (about 18.5 liters).

AdBlue consumption depends on 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, Refilling AdBlue. If you ignore the last refill reminder, it is impossible to start

the engine again after it is switched off, Warning and indicator lights.

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 _dboth 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.
