Lifting the vehicle with it's own
jack
The jack may only be used at this point.
Warning: The jack is only provided to lift the
vehicle. If work is to be carried out under the
vehicle, the vehicle must be supported on
suitable chassis stands or similar.
Lifting the vehicle
with a lifting platform or trolley jack
Before driving over the lifting platform,
ensure that there is enough clearance bet-
ween the underneath of the vehicle and the
lifting platform.
The car may only be lifted from the points
shown in the pictures.
Front: The normal jacking point.
Rear: Bearing bracket for back axle control
arms.
A trolley jack may only be used at the same
4 points as for the lifting platform, and also
under the middle of the back axle. To avoid
damaging these lifting points, a wooden
block or a rubber pad should always be
inserted between the vehicle and the jack.
The vehicle should never, under any cir-
cumstances be jacked up from under the oil
sump or the gearbox, as this could cause
severe damage.
