Warning!
The jack is designed exclusively for
jacking up the vehicle at the jack take-up
brackets. Make sure the jack arm is fully
seated in the jack take-up bracket.
If you do not position the jack correctly in
the jack take-up bracket, the vehicle can:
fall off the jack
seriously or fatally injure you or others
!
Do not position the jack on the body of the
vehicle, as this may cause damage to the
vehicle.
Depending on production date, your vehi-
cle may be equipped with either a
screw-type vehicle jack or a scissors-type
jack, see "Vehicle jack" ( page 450).
