Ve hicles without steering wheel but tons: if
ASR is malfunctioning, the00E5 indicator lamp

ASR impr oves traction, i.e. the transfer of po wer
from the tires tothero ad sur face, for a sus tained
period and, thereb y,also impr ovesth e driving
st ability of theve hicle. If the driving wheels start
to spin, ASR brakes individual drive wheels and
limits the engine torque. ASRthus significantly
assists you when pulling away and accelerating,
especially on wet or slippe ryroads.
If traction on thero ad sur face is not suf ficient,
eve n ASR will not allow youto pull away without
dif ficulty. The type of tires and totalwe ight of the

play a crucial role.
