Diagnostic Ports:
Diagnostic connectors for EFI models (e.g., 3-pin or 4-pin) allowing connection to specialized diagnostic tools.
Oil Change Interval:
Typically every 3,000-5,000 miles (or as per manual, e.g., 5,000 km / 6 months).
Spark Plug Replacement:
Recommended every 10,000-15,000 miles (specific types and gaps detailed in manual).
Valve Clearance Check:
Typically around 15,000-20,000 miles or annually. Critical for V-four engine performance.
Drive Shaft Oil Change:
Recommended at intervals specified in the manual, typically every 10,000-15,000 miles.
Engine Oil Type:
