Front 3-point ELR with pretensioners, rear 3-point seatbelts.
Oil Change Interval:
Every 5,000 miles (8,000 km) or 6 months, whichever comes first, under normal driving conditions. Severe conditions: 3,000 miles (5,000 km).
Engine Oil Filter Replacement:
At every oil change.
Air Filter Replacement:
Every 15,000 miles (24,000 km) or annually.
Spark Plug Replacement:
Approx. 60,000 miles (96,000 km) for standard iridium plugs, consult manual for specific type.
Coolant Flush Interval:
Every 30,000 miles (48,000 km) or 2 years.
Engine Oil Type:
API SG or SH, SAE 5W-30 (preferred for most conditions), or SAE 10W-30. Check manual for climate-specific recommendations.
Engine Oil Capacity:
Approx. 4.0 US quarts (3.8 Liters) with filter change for 2.0L FS-DE.
