& WARNING Risk of accident through los‐
ing a wheel
Oiled, greased or damaged wheel nuts, wheel
stud threads or conical spring washers can
cause the wheel nuts to loosen.
As a result a wheel could be lost when driv‐
ing.
Never oil or grease the threads or coni‐
#
cal spring washers.
In the event of damage to the threads or
#
conical spring washers, contact a quali‐
fied specialist workshop immediately.
Have the damaged wheel nuts, wheel
#
studs or conical spring washers
replaced.
Do not drive on.

& WARNING Risk of injury through losing a
wheel
If you loosen a wheel that is resting on the
wheel studs under load, it could drop down or
tip.
Only remove the last three wheel nuts
#
when it is clear that the wheel is resting
on the wheel studs and is not under
load.
* NOTE Damage to the chassis due to
incorrect raising of the vehicle
Do not raise vehicles equipped with a loading
crane or cargo liftgate by using the hydraulic
supports.
This would cause damage to the chassis
frame.
Use the jack to raise the vehicle.

When changing a wheel observe the following:
Only use wheel nuts that are approved for the
R
vehicle.
The wheel nuts for steel and light-alloy wheels
R
are different.
Breakdown assistance 349
The wheel nuts for light-alloy wheels on the
R
front and rear axles are different.
Wheels with a tyre pressure sensor are fur‐
R
nished with a red ring.
Observe the following notes when raising the
vehicle:
Make sure that the maximum load capacity
R
for the jack is not exceeded. The maximum
load capacity of the jack is stated on the
adhesive label affixed to the jack.
The jack is designed only to raise the vehicle
R
for a short time, e.g. while a wheel is being
changed. It is not suitable for raising and
holding the vehicle so that work can be car‐
ried out underneath it.
Only position the jack at the appropriate jack‐
R
ing point on the vehicle. Make sure that the
jack is correctly positioned on the jacking
point before raising the vehicle.
The jack support point may differ on special
R
bodies. Observe the manufacturer's operating
instructions.
Secure the vehicle before raising it to prevent
R
it from rolling away, e.g. by applying the park‐
ing brake and/or using chocks. Do not
release the parking brake while the vehicle is
raised.
The surface on which the jack is standing
R
must be firm and level. The jack must be
placed on an underlay if the surface is not
firm.
Make sure that the distance between the
R
underside of the wheel and the ground does
not exceed 30 mm. The vehicle could other‐
wise slip off the jack or tip over.
Do not change a wheel on an incline. The
R
vehicle could otherwise slip off the jack.
Do not place your hands or feet under the
R
raised vehicle.
Do not lie under the raised vehicle.
R
Make sure that nobody is in the vehicle when
R
it is raised.
When the vehicle is raised do not start the
R
engine and avoid other jolting or shaking of
the vehicle. The vehicle could otherwise slip
off the jack.
Park the vehicle on a firm and level surface.
