& 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 336, fig. 244 and
=> page 336, fig. 245.
- 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
• B e aw are of the following poi nts b efo re li fting the ve hicl e:
- 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.
- Before driving over a workshop hoist, ensure that there is
sufficient clearance between the hoist and low parts of the
vehicle. •
