Automatic Locking Differential
The automatic locking differential
engages when there is a differ-
ence in speed (slip) during accel-
eration between the front and rear
wheels of over 1.2 mph (2 km/h)
and the vehicle speed is less than
15.6 mph (25 km/h). It will disen-
gage at speeds above 16.2 mph
(26 km/h).
The yellow function indicator in
the speedometer comes on when-
ever there is a difference in speed
between the front and rear wheels
of over 1.2 mph (2 km/h), warning
of slippery road conditions.
In steering lock position 2, the
yellow function indicator lamp and
the yellow ASD warning lamp in
the instrument cluster should
come on and then must go out
with the engine running.
If the ASD warning lamp comes on
with the engine running, a mal-
function has been detected. We
recommend that you visit an
authorized Mercedes-Benz dealer
as soon as possible to have the
ASD checked.
Caution!
If the vehicle is towed with the
front axle raised, the key must not
be in steering lock position 2.
Otherwise, the automatic locking
differential control will immediately
be engaged, which may cause
loss of towing control.
Notes:
The automatic locking differential
will not engage at speeds above
15.6 mph (25 km/h). However,
above this speed, a limited-slip
effect of up to 35% is always
present.
When testing the parking brake on
a brake test dynamometer, turn off
the engine to avoid engaging the
automatic locking differential.
In winter operation, the maximum
efficiency of the automatic locking
differential can only be achieved
with Mercedes-Benz recommend-
ed M + S radial-ply tires on all four
wheels.
Acceleration Slip Control
The acceleration slip control will
engage at all vehicle speeds, if
one or both drive wheels begin to
lose traction and spin due to
excessive acceleration. While
engaged, the yellow function indi-
cator 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.
Caution!
If the vehicle is towed with the
front axle raised, the key must not
be in steering lock position 2.
Otherwise, the acceleration slip
control will immediately be en-
gaged and will apply the rear
wheel brakes.
Notes:
With the key in steering lock posi-
tion 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.
