Oil Change Interval:
Typically 5,000-7,500 miles or 6-12 months (refer to manual for specific recommendation based on usage)
Timing Belt Replacement:
Crucial: Typically every 30,000-50,000 miles or 3-5 years. Failure can cause catastrophic engine damage. Manual will specify exact interval and procedure.
Engine Oil Type:
API SG/SH or ACEA A2/A3, SAE 10W-40 or 15W-50 (check manual for exact grade and capacity)
Coolant Type:
Ethylene glycol-based antifreeze, typically a pink or blue mixture. Capacity around 7-8 liters. Refer to manual for specific type and mixture ratio.
Brake Fluid Type:
