DRIVER SUPPORT
|| location for a break are also shown with the
Time to take a break warning.
The warnings are repeated after a time if driving
behaviour has not improved.
WARNING
•
The Driver Alert Control function is sup-
plementary driver support intended to
facilitate driving and make it safer – it
cannot handle all situations in all traffic,
weather and road conditions.
•
Driver Alert Control should not be used to
extend a period of driving. The driver
should instead plan for breaks at regular
intervals and make sure they are well
rested.
•
Driver Alert Control is not a substitute for
the driver's attention and judgement. The
driver is always responsible for ensuring
the car is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

WARNING
An alarm from Driver Alert Control should be
taken very seriously, as a sleepy driver is often
not aware of his/her own condition.
If the alarm sounds or you feel fatigued:
•
Stop the car safely as soon as possible
and rest.
Studies have shown that it is just as danger-
ous to drive while tired as it is to drive under
the influence of alcohol or other stimulants.
