Werecommend that you consult your VauxhallAuthorised Repairer.Illumination of A indicates water in thefuel filter 3.Have fuel filter checked at shorter intervalsif the vehicle is subjected to extremeoperating conditions such as high humidity(primarily in coastal areas), extremely highor low outside temperatures andsubstantially varying daytime and night-time temperatures.CoolantDuring operation the system is pressurised.The temperature may therefore rise brieflyto over 100 °C.The glycol-based coolant providesexcellent corrosion protection for theheating and cooling systems as well asanti-freeze protection down to –28 °C. Itremains in the cooling system throughoutthe year and need not be changed.Use of certain anti-freezes can lead toengine damage. We therefore recommendthat you use anti-freezes that have beenapproved by Vauxhall. Picture no: 17312t.tifAnti-freeze and corrosion protectionBefore the start of the cold weather season,have the coolant checked for correctconcentration. We recommend that youconsult your Vauxhall Authorised Repairer.The amount of anti-freeze must provideprotection up to approx. –28 °C. If the anti-freeze concentration is too low, thisreduces protection from freezing andcorrosion. Top up anti-freeze if necessary.If coolant loss is topped up with water,have concentration checked and add anti-freeze if necessary.9 WarningAnti-freeze is a danger to health; it musttherefore be kept in the original containerand out of the reach of children.
