Deactivating the A cceleration Skid Control (A SR)See Section 4, Understanding Your Instrument Panel,
for switch locations.
When driving with snow chains, in
deep snow, or on sand or gravel, it
can be beneficial to deactivate the
acceleration skid control (ASR).
The engine
’s torque is then no longer
limited and the drive wheels are free
to spin, which can help them cut into
loose surfaces.
The ASR can only be shut off with the engine running.
If the engine is shut off with the ASR deactivated, the
ASR is automatically re-activated after the engine is
started again.Cargo/passenger vans type 2500 C/HC/SHC only:
If there is a danger of skidding, and/or starting at a
speed of 38 mph (60 km/h) ESP activates ASR
automatically.
WARNING!
On a slippery road surface if both drive wheels
start to spin there is a risk of skidding. Adapt your
speed and driving style to the prevailing road,
traffic and weather conditions.
P54.25-0294-20
WARNING!
Vehicles type 2500 C/HC/SHC only:
Even when ASR is deactivated, ESP remains
active and regulates braking to improve stability
as necessary. The warning lampv flashes in
the speedometer.
The danger of your vehicle’s brake system
overheating and being damaged is increased
during long, demanding application of the
brakes. Furthermore, an overheated brake system
could result in a longer stopping distance.
Thus, only deactivate ASR if it is absolutely
necessary.
