Checkingthe engine oil level usingthe oildipstick
\nWARNINGRisk of burns from hot com‐ponent parts inthe engine compartment
Certain component parts inthe engine com‐partment can beveryhot, e.g.the engine,the cooler and parts oftheexhaust system.
Letthe engine cool down and onlytouchthe component parts describedasfollows.
Requirements:The engine must havean oil dipstick.If not,theengine oil level can bechecked only withthe on-board computer .
Depending onthe engine,the oil dipstick may beinstalled inthe engine compartment in differentlocations.
Thewaiting time beforecheckingthe oil levelwhenthe engine is at normal operatingtempera‐ture isfiveminutes.
Parkthevehicle on a level surface.
Pull oil dipstick1out and wipe off.
