1996 Mercedes-Benz S320 S420 S500 W140 Owners Manual

Acceleration Slip Control (ASR)
Important!
Have the ASR checked at your
authorized Mercedes-Benz dealer as
soon as possible.
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.
If the ASR warning lamp flashes, adapt
your speed and driving to the
prevailing road conditions.
With the ABS malfunctioning, the
ASR is also switched off.
Caution!
Driving the vehicle with varied size
tires will cause the wheels to rotate at
different speeds, therefore the
acceleration slip regulation may
activate (yellow ASR malfunction
indicator lamp in instrument cluster
comes on). For this reason, all wheels,
including the spare wheel, must have
the same tire size.
If the vehicle is towed with the front
axle raised (see Towing the vehicle in
Index), the key must not be in steering
lock position 2. Otherwise, the
acceleration slip regulation will
immediately be engaged and will apply
the rear wheel brakes.
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.
Notes:
When testing the parking brake on a
brake test dynamometer, the key must
not be in steering lock position 2.
Otherwise, the acceleration slip
regulation will immediately be engaged
and will apply the rear wheel brakes.
As traction on the road surface

lamp in the instrument cluster and the
yellow ASR warning lamp in the
speedometer dial come on. They must
go out when the engine is running.
increases, the allowable engine torque
also increases again and the brake is no
longer applied to drive wheels.
In winter operation, the maximum
effectiveness of the acceleration slip
regulation is only achieved with
Mercedes-Benz recommended M + S
radial-ply tires and/or snow chains.
If the ASR malfunction indicator lamp
comes on with the engine running, a
malfunction has been detected.
Pressing the accelerator pedal will
require greater effort. Only partial
engine output is available.
