  01

  Gasoline engine oil and filter

  Exact reference available

  Follow the gasoline Oil Life System: change oil and filter as soon as possible within 600 miles of the message, and at least once a year even without a message; reset after every change. If accidentally reset, change within 3,000 miles since the previous change, not a routine 3,000-mile interval. Use Maintenance I when the message occurs within 10 months of purchase or within 10 months after Maintenance II. Use Maintenance II after prior Maintenance I; always use II at 10 months or more since service or if no message appears for one year. Diesel requires its separate supplement. Fuel permission and octane are separate: VIN Z/L59 alone permits E85; none of these documented standard offerings is L59. VIN N/LQ9 specifies 91+ premium and also permits 87+ regular with possible reduced acceleration/light knock. Verify actual VIN and engine before using an engine-specific reference.

  Routine owner checks and Maintenance I/II inspections

  Sourced interval available

  At each fuel fill check oil, coolant and washer levels using the full procedures. Monthly check pressures including spare, secure spare storage and tire wear; high-mileage highway use may need rotation before the oil message. I/II inspections include leaks and brakes; II adds steering/suspension, cooling, wipers, restraints, body lubrication and applicable fluid checks. Separately from the 150,000-mile/five-year cooling service, the manual recommends system/cap pressure testing and exterior radiator/condenser cleaning at least annually. At least each spring flush corrosion/debris from the underbody. The first 100/1,000/6,000-mile wheel-nut instruction is explicitly dual-wheel, not assigned to these single-wheel records. Use the full manual; inspections are not automatic component replacement.

  Chassis lubrication

  Sourced interval available

  Lubricate specified chassis components at Maintenance I and II. Severe-commercial operating conditions require regular 3,000-mile lubrication; this is not a universal interval. Ball joints must be at least 10°F component temperature before lubrication, not an ambient-temperature shortcut. The period specification is NLGI No. 2 Category LB or GC-LB; no current product is assigned.

  Rotate at 5,000–8,000 miles and sooner for unusual wear, using the actual installed tire/wheel pattern; also check wear at I/II and monthly. Rear/front axle and transfer-case levels do not need routine checking absent suspected leakage or unusual noise. Have fluid loss inspected/repaired. Follow the full 1500-specific rear-axle and cold/warm front-axle procedures; do not borrow HD fill levels or infer all systems fill to the plug.
