& WARNING
• To reduce the risk of serious injury and vehicle damage .
- Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated
=> page 371 , fig . 306 and
=> fig. 307.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balance. This might happen , for
example, when heavy components such as the engine block or
transmission are removed .
• When removing heavy components like these, anchor vehicle
to hoist or add corresponding weights to maintain the center of gravity. Otherwise , the vehicle might tilt or slip off the hoist,
causing serious personal injury .
0 Note

- The vehicle should never be lifted or jacked up from under­
neath the engine oil pan , the transmission housing , the front or
rear axle or the body side members . This could lead to serious
damage .
- To avoid damage to the underbody or chassis frame, a rubber
pad must be inserted between the floor jack and the lift points .
- Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist . _..
