Oil Change Interval:
Typically every 10,000 miles (16,000 km) or 12 months, whichever comes first, depending on driving conditions and oil specification. Consult manual for specific recommendations.
Timing Belt Replacement:
For V8 engines, typically a timing chain system is used, requiring inspection but not periodic replacement like a belt. V6 engines might have timing belts; check specific engine codes for interval (often 60,000-100,000 miles or 5-7 years).
Transmission Fluid Change:
Often considered a 'lifetime fill' by manufacturers, but recommended by many mechanics to change every 60,000-100,000 miles, especially in heavy-duty use. Specific procedures and fluid types are detailed in the manual.
Engine Oil Type:

Coolant Type:
G12 (pink) or G12+ antifreeze concentrate mixed with distilled water. Ensure correct coolant ratio for climate.
Transmission Fluid Type:
Likely G 052 162 A1 (ATF) for automatic transmissions. Manual transmissions will use different gear oil specifications (e.g., G 052 171 A2).
Brake Fluid Type:
DOT 4 or DOT 5.1. Ensure consistent fluid type across the system.
Common Wear Items:
Air suspension components (struts, compressor, lines), ignition coils, mass airflow sensors (MAF), ABS wheel speed sensors, oxygen sensors, coolant temperature sensors, thermostat, and certain electronic control modules.
