Be sure to ask your dealership service advisor or technician about the
multi-point vehicle inspection. It’s a comprehensive way to perform a
thorough inspection of your vehicle. It’s your checklist that gives you
immediate feedback on the overall condition of your vehicle. You’ll know
what’s been checked, what’s okay, as well as those things that may
require future or immediate attention. The multi-point vehicle inspection
is one more way to keep your vehicle running great!Scheduled Maintenance
