The air conditioner is most efficient when the w in­dows an d the power sunroof are closed. However,
if th e vehicle is sta ti o nary and the passenger com­partment becomes very hot due to sunlight, opening the w indows briefly may speed up the cooling proce ss.

blend lev els hi gher than 5% (5% methyl est er
blends are sometime s designated or labeled as
B5). The propertie s of methyl ester biodiesel
blend s in leve ls greater than 5% may cause riou s damage to the fuel injection system and to the engine. This co uld lead to expensive repairs that will not b e cove red any Volkswagen Limited
