  Gasoline engine oil and filter

  Exact reference available

  Follow the gasoline Oil Life System. When the change message appears, change oil and filter within 600 miles; change at least once a year even without a message, then reset the system. If accidentally reset, change within 3,000 miles of the previous change. This is not a fixed routine mileage. Use Maintenance I when the message appears within 10 months of purchase or the last Maintenance II. Use Maintenance II after a previous Maintenance I, when the message appears 10 months or more since service, or when no message appears for a year. Generally start with I, then II, and alternate; follow the full original schedule.

  Engine-air filter and optional restriction indicator

  Exact reference available

  Identify whether the optional restriction indicator is fitted. These are equipment-dependent alternatives, not proof that a listed configuration has that hardware. The period owner table has inconsistent standard/high-capacity labels. Any catalog reference shown applies only to its stated application and does not establish a supersession chain or which housing is fitted.

  If a restriction indicator is fitted

  Inspect the indicator at every oil change. Replace the filter and reset the indicator when it is black or in the red/orange change zone. Dusty or dirty operation also requires inspection at each oil change. No fixed 50,000-mile replacement branch is assigned to this hardware.

  At each fuel fill, early wheel checks and monthly

  At each fuel fill check engine oil, coolant and washer levels using the proper fluids and original precautions. If the actual vehicle has dual wheels, check wheel-nut torque at the first 100, 1,000 and 6,000 miles using the actual torque specification; no torque value is assigned here. Monthly, check actual placard tire pressures and spare security; inspect unusual wear as needed. Follow the original spare-retention procedure.

  Maintenance I and II common inspections

  At both Maintenance I and II, inspect for leaks or damage, inspect the brake system and check coolant/washer levels. The brake inspection covers lines, hoses, wear and the disc/drum/parking-brake components actually fitted. Fluid loss can indicate a problem: have it inspected and repaired, then recheck; do not just repeatedly top up. Tire rotation and chassis conditions appear as separate topics below.

  Maintenance II inspections and body lubrication

  At Maintenance II inspect suspension/steering, hoses, CV boots and axle seals; inspect cooling hoses/pipes/fittings/clamps, wipers and restraint hardware; lubricate fitted locks, body/seat/hood/tailgate/fuel-door hardware; check automatic transmission fluid level by the original procedure. Repair defects as directed, rather than replacing every inspected component. More frequent body lubrication may be needed in corrosive exposure. Correct weatherstrip treatment is a separate material choice. Annual cooling-system/cap pressure testing and exterior radiator/condenser cleaning are recommended by the manual.

  Annual safety checks and spring underbody flushing

  At least annually follow the complete original starter-switch, automatic shift-lock, ignition/transmission-lock and parking-brake/Park-mechanism checks. These procedures warn that the vehicle can move suddenly and cause injury or damage; use the full manual and qualified-service assistance, not abbreviated test steps. At least each spring flush corrosive materials and trapped debris from the underbody as directed.

  Tire rotation and axle-level check conditions

  Sourced interval available

  The tire section calls for rotation every 5,000–8,000 miles and sooner for unusual wear, with wheel-alignment and tire/wheel-damage checks. The schedule also lists rotation at both Maintenance I and II. Match the actual single/dual-wheel and tread pattern to the original diagrams; a same-tread single-wheel pattern is not a universal pattern for different hardware. Secure the spare and use actual placard pressures. Rear-axle fluid does not need a regular level check unless a leak or unusual noise is suspected; have a problem inspected/repaired. No scheduled axle-fluid replacement or one fill quantity is assigned.
