Important Safety Notes - Mercedes-Benz Unimog Operating Instructions Manual

Observe the following if the vehicle has to be
parked outdoors at extremely low tempera-
tures:
X
Interrupt the voltage supply with the bat-
tery isolator switch (
X
If necessary, ensure adequate vehicle light-
ing by using an external lighting system
(e.g. warning lamps).
X
Make sure that the fuel tank and the
®
AdBlue reservoir are filled above the
reserve level.
It may be necessary to ventilate the fuel
i
system after long periods out of use if the
fuel level is too low (
X
For longer periods out of use: charge the
batteries every two days.
or
X
Remove the batteries and store at a tem-
perature above 0 †.
Snow chains

Important safety notes

Snow chains increase traction in wintry con-
ditions.
German law requires that snow chains be
removed as soon as possible once the road is
clear of snow. The vehicle's driving and brak-
ing characteristics will be adversely affected
if you drive on roads that are clear of snow
with snow chains fitted to the vehicle.

WARNING
If you drive too fast with snow chains fitted,
they may snap. As a result, you could injure
others and damage the vehicle. There is a risk
of an accident.
Observe the maximum permissible speed for
operation with snow chains.
! Only use snow chains that have been
approved and recommended for Mercedes-
Benz. This will prevent you from causing
damage to the vehicle. If you have ques-

Winter operation
tions, consult a qualified specialist work-
shop.
! Mercedes-Benz recommends fitting snow
chains on all wheels on the front and rear
axles.
If, contrary to Mercedes-Benz recommen-
dations, snow chains are not fitted on all
axles, at least the interaxle lock must be
engaged on vehicles with permanent all-
wheel drive. There is otherwise a high risk
of damaging the interaxle differential.
If, contrary to Mercedes-Benz recommen-
dations, snow chains are fitted diagonally,
there is a high risk of damaging the differ-
ential. Repeated and sustained spinning of
the wheels may cause damage to the dif-
ferentials.
There may be slight deviations from the
descriptions in these Operating Instructions
regarding the use of snow chains, due to legal
requirements in individual countries. Observe
the legal requirements in all countries con-
cerned.
When fitting snow chains, observe the fitting
instructions of the chain manufacturer.
Checking the tyre clearance
! If the clearance between the snow chain
and steering linkage is less than 25 mm, the
snow chain could damage the steering link-
age. In this case, remove the snow chains
again. Have the steering geometry checked
at a qualified specialist workshop.
Observe the following when fitting snow
chains to the front axle:
X
Apply the parking brake.
X
Fit snow chains in accordance with the fit-
ting instructions of the snow chain manu-
facturer.
X
Start the engine.
