Repair Procedures: Replacement

CAUTION:
  • Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift.

    (Refer to General Information - " LIFT AND SUPPORT POINTS  ") 

NOTE:
  • Prolonged and repeated contact with mineral oil will result in the removal of natural fats from the skin, leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially harmful contaminants which may cause skin cancer.
  • Exercise caution in order to minimize the length and frequency of contact of your skin to used oil. Wear protective clothing and gloves. Wash your skin thoroughly with soap and water, or use waterless hand cleaner, to remove any used engine oil. Do not use gasoline, thinners, or solvents.
  • Be careful not to contaminate nearby parts when replacing engine oil.
  • In order to preserve the environment, used oil and used oil filter must be disposed of only at designated disposal sites.
