3. There may be issues with the detection
of vehicles in front, when going into
and coming out of a bend.
4. When moving around a stationary
vehicle. This may cause uncertainty as
to which vehicle should be followed.
5. When the vehicle ahead turns out of
your lane. This may cause uncertainty
as to which vehicle should be followed.
In these situations Adaptive Cruise Control
(ACC) may operate unexpectedly. The
driver should stay alert and intervene if
necessary.
ACC MALFUNCTION
If a fault occurs while ACC, or Follow
mode is operational, ACC will switch off
and cannot be used until the fault is
cleared. The message DRIVER
INTERVENE is displayed briefly in the
Message centre and is then replaced by
the message CRUISE NOT AVAILABLE.
If a fault with ACC, or any related system,
occurs at any other time, the message
CRUISE NOT AVAILABLE will be
displayed. It will not be possible to
activate ACC in any mode.
Accumulations of dirt, snow or ice on the
radar sensor or cover may inhibit ACC
operation. Fitting of a vehicle front
protector or metallised badges may also
affect ACC operation.
If this occurs in ACC cruise/Follow mode,
the audible alarm sounds and the message
DRIVER INTERVENE is displayed briefly.
The message RADAR SENSOR BLOCKED
will then be displayed.
Note: The same messages may also be
displayed while driving on open roads with
few objects for the radar to detect.
Clearing the obstruction allows the system
to return to normal operation. If the
obstruction is present when ACC is
inactive (e.g., on initial starting or with
ACC switched off), the message RADAR
SENSOR BLOCKED will be displayed.
Tyres, other than those recommended for
your vehicle, may have different
circumferences. This can affect the correct
operation of ACC.
FORWARD ALERT FUNCTION
The system may not react to slow
moving vehicles.
Forward alert uses the same radar
sensor as Adaptive Cruise Control
(ACC). The same performance
limitations apply. See 129,
ADAPTIVE CRUISE CONTROL
OVERVIEW.
Forward alert can be enabled/disabled,
via Driver Assistance or Driving features
in the Instrument panel menus. See 49,
INSTRUMENT PANEL MENU.
The warning lamp in the Instrument panel
illuminates when Forward alert is enabled.
See 57, FORWARD ALERT (GREEN).
Forward alert provides limited detection
and warning of objects close ahead while
the vehicle is moving forwards. If a vehicle
or object ahead is within the user defined
sensitivity area, a warning tone will sound
and the FORWARD ALERT message will
be displayed in the Message centre.
Emergency Brake Assist (EBA) will be
activated. See 114, EMERGENCY BRAKE
ASSIST (EBA).
The driver must take appropriate action
immediately.
