Vehicle lift and support locations
1. Notice about vehicle condition when jacking up As a rule, the vehicle must be unloaded when jacking up. Never jack up or lift up the vehicle loaded with things of heavy weight.  when removing any parts of heavy weight like the engine and transmission, the center of gravity of ...

Precaution
1. Check that the battery cables are connected to the correct terminals. 2. Disconnect the battery cables when the battery is given a quick charge. 3. Do not perform tests with a high voltage insulation resistance tester. 4. Never disconnect the battery while the engine is running. 5. Check that ...
