DRIVER SUPPORT
||
A camera monitors the traffic lane's marker lines
and compares the direction of the road with the
driver's movements of the steering wheel.
The vehicle is moving erratically in the lane.
If driving behavior becomes
considerably erratic, the driver
will be alerted by this symbol in
the instrument panel, an audi-
ble signal and the message
Time for a break
If the vehicle is equipped with Sensus
Rest Stop Guidance
Navigation* and the
tion is activated, suggestions will also be provided
for suitable places to take a break.
The warning will be repeated after a short time if
driving behavior does not improve.

WARNING
Driver Alert Control must not be used to
extend a period of driving. The driver should
plan in breaks at regular intervals and make
sure they are well rested.
WARNING
• The function is supplementary driver sup-
port intended to facilitate driving and help
make it safer – it cannot handle all situa-
tions in all traffic, weather and road condi-
tions.
• The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion.
• Driver support functions are not a substi-
tute for the driver's attention and judg-
ment. The driver is always responsible for
ensuring the vehicle is driven in a safe
.
manner, at the appropriate speed, with an
appropriate distance to other vehicles,
func-
and in accordance with current traffic
rules and regulations.
WARNING
An alarm from Driver Alert Control should be
taken very seriously since a sleepy driver is
often not aware of their own condition.
If the alarm sounds or you feel fatigued:
• Stop the vehicle safely as soon as possi-
ble 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.
