General maintenance items and procedures are as follows
  1. GENERAL NOTES Maintenance requirements vary depending on the country. Check the maintenance schedule in the owner's manual supplement. Following the maintenance schedule is mandatory. Determine the appropriate time to service the vehicle using either miles driven or time (months) elapsed, whichever reaches the specification first. Failing to check each vehicle part could lead to poor engine performance and increase exhaust emissions.
  2. TIRES Check the tire inflation pressure with a gauge. Make adjustments if necessary. Check the surfaces of the tires for cuts, damage or excessive wear.
  3. WHEEL NUTS Check for nuts that are loose or missing. Tighten them if necessary.
  4. TIRE ROTATION Check the maintenance schedule in the owner's manual supplement.
