Features:
No driver assistance features like ABS (standard), traction control, or ride modes were available on these models.
Features:
No modern connectivity features like Bluetooth or USB ports.
Oil Change:
Typically every 2,500-5,000 miles or annually, whichever comes first (consult specific year manual).
Primary Fluid Change:
Recommended at 10,000-15,000 mile intervals, or as specified in the manual.
Spark Plug Replacement:
Typically every 10,000-15,000 miles.
Belt Drive Inspection:
Regular inspection for wear, tension checks, and cleaning (no lubrication required).
Engine Oil:
