Snow chain switch
Driving with Snow Chains
When driving with snow chains,
press the upper half of the snow
chain switch, located on the in
strument panel (the indicator lamp
in the switch comes on) to obtain
maximum possible traction.
This mode is effective at speeds
up to 25 mph (40 km/h). It remains
stored in memory up to
37 mph (60 km/h) and auto
matically engages again when the
vehicle speed drops below
25 mph (40 km/h).
The mode is canceled in memory
above 37 mph (60 km/h) and the
indicator lamp in the switch goes
out.
To switch off: press lower half of
switch (the indicator lamp in the
switch goes out).
Automatically Engaging
Four-wheel Drive (4MATIC)
The yellow function indicator lamp
in the speedometer and the yellow
4MATIC warning lamp will come
on with the key in steering lock
position 2 and should go out with
the engine running.
When driving, the function in
dicator lamp comes on as soon as
the front wheel drive, or the
differential locks are engaged.
The front-wheel drive as well as
the differential locks are auto
matically engaged if road con
ditions and driving style result in
wheel spin (difference in rpm
between the front and rear
wheels).
The illumination of the function
indicator lamp also informs the
driver that the tires have reached
their critical limits of traction.
