Lifting the vehicle
Important safety precautions
Be aware of the following hazards before l ift ing the vehic le w ith a
w ork sho p ho is t or f lo or jack :
• The vehicle should never be lifted or jacked up from underneath
the engine oil pan, the transmission housing , the front or rear axle
or the body side members . This could lead to serious damage.
• Use lifting equipment with padded contact surfaces to avoid
damage to the underbody or chassis frame.
• Alternatively, cover the contact surfaces on workshop hoist or
floor ja ck with rubber pads before lifting.
• 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 suffi ­
cient clearance between the hoist and low parts of the vehicle .
& 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
=> fig . 239 and => fig . 240 .
• 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 distri­
bution and balance . This might happen, for example, when heavy
components such as the engine block or transmission are
removed .
• When removing such heavy components, 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 .

• Always support your vehicle with safety stands if it i s neces­
sary to work underneath the vehicle. The jack supplied with the
vehicle is not adequate for this purpose and could collapse

the ground , always make sure the vehicle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in
" P " (Park position) and the park brake is firmly
applied.
