Raising the vehicle G
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 fall 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
tailgate is opened or closed), and you could
be seriously injured.
G
Risk of accident
If you fail to position the jack correctly, the
vehicle may:
R slip off the jack
R injure you or others
R be damaged
Thus, it is important to make sure that the jack
is positioned correctly in the respective jack-
ing points. Before positioning the jack,
remove any dirt that may have collected in the
jacking points.
The jacking points for the jack are located
behind the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels (arrows). X

Risk of accident
Replace damaged or corroded wheel bolts.
Never oil or grease wheel bolts. This could
cause the bolts to loosen in the wheel hub. G
Risk of accident
If a wheel hub thread is damaged, do not drive
the vehicle any further. Consult a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre or "Service 24". In particular, work rel-
evant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop. G
Risk of accident
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz and the respec-
tive wheel. Other bolts may work loose or
damage the brake system.
Do not tighten the wheel bolts completely
while the vehicle is still jacked up. The vehicle
could topple off the jack. 1
