Important notes on using the jack:

Only use the vehicle-specific jack that has

holding the vehicle for a short time while a
1 and turn wheel is being changed and not for mainte‐
nance work under the vehicle.
The jack must be placed on a firm, flat and

non-slip surface. If necessary, use a large,
on socket 2 and
load-bearing, non-slip underlay.
The base of the jack must be positioned ver‐
R
tically under the jack support point.
Rules of conduct when the vehicle is raised:
Never place your hands or feet under the

vehicle.
Do not lie under the vehicle.

completely.
