DRIVER DROWSINESS MONITOR
(DDM)
The purpose of the Driver Drowsiness
Monitoring (DDM) system is to evaluate
driving technique for signs of driver
fatigue. If the system determines the driver
is fatigued, the vehicle displays the
warning, Take a break!, in the Instrument
panel for 30 seconds, along with an
audible chime. If driving continues, a
further warning displays in the Instrument
panel, again with an audible chime, until
the OK button on the steering wheel
menu control is pressed.
DDM is always active at vehicle speeds
between 60 km/h (37 mph) and 180 km/h
(112 mph). DDM can be switched off via
Driving Features in the Instrument panel
menus. See 49, INSTRUMENT PANEL
MENU.
If the DDM system develops a fault, a
double warning icon displays in the
Message centre. DDM is then unavailable
until the problem is rectified. If the fault
does not clear after the ignition is switched
off and on again, consult a Retailer/
Authorised Repairer.
TRAFFIC SIGN RECOGNITION
The Traffic sign recognition
system is a driving aid only. It
remains the driver's responsibility
to drive with due care and
attention, in a manner which is
safe for the vehicle, its occupants
and the other road users. The
driver should still observe all
other road signs, road markings
and situations that are not
detected or recognised by the
Traffic sign recognition system.
The Traffic sign recognition system uses
the forward-facing camera, located in the
base of the rear-view mirror. This detects
speed signs, no overtaking signs and
variable overhead speed signs and
displays symbols of the detected signs, in
the Message centre. Traffic signs with
extra information (for example, reduced
speed limits for wet road conditions) are
also detected and compared with the
vehicle’s systems (for example, rain sensor,
wipers, etc.) and may also be displayed in
the Message centre. Speed limit
information from the Navigation system
is displayed for roads with no signage.
Note: If the standard road navigation is
not available, the Traffic sign recognition
system uses the camera only.
Note: Make sure that the windscreen area
in front of the rear-view mirror is kept
clean and free of obstructions, for
example, stickers, debris, mud, snow, ice,
etc.
The Traffic sign recognition system can be
switched on and off via the Instrument
panel menu. See 49, INSTRUMENT
PANEL MENU. The system operates up
to a maximum speed of 250 km/h (155
mph).
The three basic functions of the Traffic
sign recognition system are as follows:
• Speed limit detection: A
corresponding sign is displayed in the
Message centre.
• Speed alert: When the vehicle's speed
is greater than (or equal to) the
detected speed limit, a flashing red
ring, around the displayed speed limit
sign, is displayed in the Message
centre.
