Notes on driving in winter
& WARNING Risk of explosion through liq‐
uid or gaseous starting aids
Liquid or gaseous starting aids immediately
react with fuel vapours and are highly flam‐
mable.
Do not use liquid or gaseous starting
#
aids to start the engine.
* NOTE Damage to the differential
For vehicles without acceleration skid control
(ASR): changes from slippery to high grip
roadways whilst the drive wheels are spinning
can result in damage to the differential.
Avoid letting the drive wheels spin.

Notes on snow chains
& WARNING Risk of accident through
breaking snow chains
If you drive too fast with snow chains fitted,
they may break.
As a result, you could injure others and dam‐
age the vehicle.
Maximum permissible speed for operat‐
#
ing with snow chains.
* NOTE Damage to the vehicle due to snow
chains
Only use snow chains that are approved
#
and recommended for Mercedes-Benz.
This avoids damage to the vehicle. If you
have any questions, consult a qualified
specialist workshop.
* NOTE Damage to the differential
Mercedes-Benz recommends mounting
#
snow chains on all drive wheels. If snow
chains are not mounted on all drive
wheels, the interaxle differential lock
must be engaged on vehicles with per‐
manent all-wheel drive.
The law may require that snow chains be
removed again as soon as possible once the
roadway is clear of snow. The vehicle's driving
and braking characteristics will be adversely
affected if you drive on roadways that are clear of
snow with snow chains fitted to the vehicle.
Observe the notes of the snow chain manufac‐
turer on the maximum permissible speed for
operation with snow chains.
When using the snow chains described here,
observe the legal requirements for the country
you are currently in.
Do not use twin chains on vehicles with roll con‐
trol. Only fit snow chains on the exterior wheels.
Vehicles with electric power steering: if you
change the mechanical axle stops, e.g. when
using snow chains, have the electric power steer‐
ing taught-in at a qualified specialist workshop.
