The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface.
Make sure that the jack arm is fully seated
in the jack take-up bracket. Always lower
the vehicle onto sufficient capacity jack-
stands before working under the vehicle.

The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a mounted
Minispare wheel. Adapt your driving style
accordingly.
The Minispare wheel is for temporary use
only. When driving with a Minispare wheel
mounted, ensure proper tire pressure and
do not exceed a vehicle speed of
50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Light
Truck Center as soon as possible to have the
Minispare wheel replaced with a regular
road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP

The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle.
Never start the engine when the vehicle
is raised.
Never lie down under the raised vehicle.
!Do not place wheel bolts in sand or dirt.
This could result in damage to the bolts
and wheel hub threads.
!Wheel bolts2 must be used when
mounting 17" light alloy rims or the
Minispare wheel. The use of any wheel
bolts other than wheel bolts2 for
17" light alloy rims or the Minispare
wheel will physically damage the vehi-
cle’s brakes.
