► We were graced with the pres­ence of a 2010 Porsche Cayenne hybrid for ser­vice. While some of the ve­hi­cle sys­tems are com­pletely dif­fer­ent from the stan­dard petrol ver­sion, the en­gine is pretty much the same.

Although the main bat­tery pack does not need to be iso­lated when car­ry­ing out rou­tine ser­vic­ing, it is good prac­tice to en­sure that the key is re­moved from the ve­hi­cle, to pre­vent any er­ror. The high volt­age sys­tem does not need to be touched or al­tered dur­ing the ser­vice but it’s im­por­tant to re­mem­ber that the or­ange ca­bles at the back of the en­gine bay and un­der the ve­hi­cle will be car­ry­ing a volt­age of around 600V DC and a jolt of this size will al­most cer­tainly be fa­tal.

The hybrid bat­ter­ies should al­ways be dis­con­nected be­fore work as­so­ci­ated with the drive sys­tems is car­ried out, and we would not rec­om­mend this is done with­out plac­ing the ve­hi­cle in an ex­clu­sion zone and using the full safety kit in­clud­ing the pro­tec­tive gloves and mat. The fu­ture will see many more hy­brids and elec­tric ve­hi­cles on the road and in­de­pen­dent garages look­ing to the fu­ture may be well ad­vised to be equipped to work on them, giv­ing them a head start on the com­pe­ti­tion.

 ??  ?? Nor­mal ser­vic­ing can be car­ried out, but treat the or­ange ca­ble with caution.
