Driver Alert Control Limitations - Volvo XC 90 Owner's Manual

WARNING
•
DAC is not intended to extend the dura-
tion of driving. Always plan breaks at reg-
ular intervals to help remain alert.
•
A warning from DAC should not be
ignored. A driver may not be aware of
how fatigued he/she has become.
•
In certain cases, fatigue may not affect
the driver's behavior. In situations of this
type, no warning will be provided. There-
fore, it is important to take breaks at reg-
ular intervals, regardless of whether or
not DAC has given a warning.

Driver Alert Control limitations

The camera used by DAC (and other driver sup-
port systems such as Adaptive Cruise Control*)
has certain limitations.
In certain situations, DAC may provide warnings
even if the driver's driving pattern has not
become erratic:
•
in strong crosswinds
•
on grooved road surfaces
