ENGINE OIL REPLACEMENT [L3 WITH TC]

WARNINGHot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the engine oil have cooled. A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall, causing death or serious injury. Never work around or under a lifted vehicle if it is not securely supported on safety stands. Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after working with engine oil.
CAUTIONIf engine oil is spilled on the exhaust system, wipe it oft completely. If you fail to wipe the spilled engine oil, it will produce fumes because of the heat.

OIL FILTER REPLACEMENT [L3WITH TC]

WARNINGHot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the engine oil have cooled. A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall, causing death or serious injury. Never work around or under a lifted vehicle if it is not securely supported on safety stands. Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after working with engine oil.
CAUTIONIf engine oil is spilled on the exhaust system, wipe it off completely. If you fail to wipe the spilled engine oil, it will produce fumes because of the heat. To avoid damage to the oil filter, use only specified oil filter.
