lowing message in the multifunction

iVehicles equipped with FSS {PLUS} (Flexible
Service System {PLUS}) only (Canada vehicles):

FSS {PLUS} evaluates engine temperature,
oil level, vehicle speed, engine speed, dis-
tance driven and the time elapsed since your
last service and calculates other mainte-
nance service work required.

The interval between maintenance services
depends on your driving habits. A gentle
driving style, moderate engine speeds and
the avoidance of short-distance trips will
lengthen the interval between services.

has dropped to approximately the mini-
mum level.

come on intermittently and then stay on if
the oil level drops further.Visually check for oil leaks. If no obvious oil
leaks are noted, drive to the nearest
service station where the engine oil should
be topped to the required level with an
approved oil specified in the Factory
