Important safety notes
Snow chains increase traction in wintry condi-
tions.

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-
tions, consult a qualified specialist work-
shop.
! Mercedes-Benz recommends that you fit
snow chains to all drive wheels. If your vehi-
cle has permanent all-wheel drive and you
do not fit snow chains to all drive wheels,
activate the inter-axle lock. You could other-
wise damage the differential.
Do not exceed the maximum permissible
speed of 50 km/h for snow chains.
The law may require 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.

Winter operation

Due to legal requirements in individual coun-
tries, there may be slight deviations from the
description in these Operating Instructions
regarding the use of snow chains. Observe the
legal requirements in all countries concerned.
When fitting snow chains, observe the fitting
instructions of the chain manufacturer.
Checking the wheel 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.
Clearance between snow chain and drag link
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 chain manufacturer.
X
Start the engine.
X
Turn the steering wheel towards the co-
driver side to the stop.
With the steering on full lock, there must be
a clearance of at least 30 mm between the
snow chain and the drag link.
