faces (for example, icy or snow-covered).
Despite the control systems, the driven
wheels could spin, affecting the stability of
the vehicle: risk of accident!
Note
The ABS and ASR will only operate cor-
●
rectly if the four wheels have identical
tyres. Any differences in the rolling radius
of the tyres can cause the system to re-
duce engine power when this is not desired.
The regulating processes of the systems
●
can make noises due to their operation.
