Risk of injury
The jack is designed only to raise the vehicle
for a short time while a wheel is being
changed.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
The vehicle could otherwise slip off the jack
and seriously injure you.
Do not start the engine at any time while the
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack
(e.g. if the engine is started or a door or the
boot lid is opened or closed) and seriously
injure you.
