used
In these or similar operating conditions, have the
interior air filter changed more frequently.
If the vehicle is subjected to increased loads, the
tyres must be checked more frequently. You can
obtain further information at a qualified specialist
workshop.

the battery is connected. To comply with the
time-based service, deduct the non-operational
times with a disconnected battery from the
service message days displayed.
