Acceleration Slip Control (Asr); Driving With Snow Chains - Mercedes-Benz 300 SL Owner's Manual

Acceleration Slip Control (ASR)

The acceleration slip control will
engage at all vehicle speeds, if one or
both drive wheels begin to lose traction
and spin. While engaged, the yellow
function indicator in the speedometer
lights up.
With the acceleration slip control
engaged, the brake is applied to the
spinning drive wheel until it regains
sufficient traction. If both drive wheels
lose traction and spin, the brake is
applied to both drive wheels and
simultaneously, engine torque is
limited.
As traction on the road surface
increases, the allowable engine torque
also increases again and the brake is no
longer applied to drive wheels.
Snow chain switch

Driving with Snow Chains

When driving with snow chains, press
the upper half of the snow chain
switch, located on the instrument panel
(the indicator lamp in the switch
comes on).
This mode is effective at speeds up to
40 km/h (25 mph). It re-mains stored
in memory up to 60 km/h (37 mph)
and automatically engages again when
the vehicle speed drops below 40 km/h
(25 mph).
The mode is canceled in memory
above 60 km/h (37 mph) 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).
Notes:
With the key in steering lock position
2, the yellow function indicator lamp
and the yellow ASR warning lamp in
the instrument cluster come on. They
must go out with the engine running.
If the ASR warning lamp comes on
with the engine running, a malfunction
has been detected. Pressing the
accelerator pedal will require greater
effort. Only 2/3 of engine output is
available.
Have the acceleration slip control
checked at your authorized
MERCEDES-BENZ dealer as soon as
possible.
