Adaptive cruise control (ACC)

Adverse weather conditions
During adverse weather conditions such as
heavy rain or snowfall, the sensitivity of radar
blockage detection is incr eased, so that it can
correctly detect any reduced performance
caused by a blocked sensor.
During these conditions, the warning message
ACC SENSOR BLOCKED may be displayed
more frequently, especially in areas where
there are few roadside objects for the radar to
detect.
FORWARD ALERT FUNCTION
Limited detection and warning of objects
ahead, is provided during ACC operation by the
ACC FORWARD ALERT warning. The enhanced
forward alert feature additionally provides
warnings when ACC is not engaged; if an object
is detected close ahead, then the warning tone
and message will be issued. The brakes will not
be applied. The forward alert system does not initiate any
action. The driver must
take appropriate action
when the FORWARD ALERT message is
displayed. However, the system monitors
driver actions (e.g. braking, steering or
indicating) and may not initiate the warning
display if the appropriate action has been taken
early enough.
The Forward alert function may be switched on
or off using the forward alert switch, located
where shown.
When the indicator in the
instrument panel is on, Forward
alert is active.
The sensitivity of the warning may be changed:
• Press the gap decrease button when ACC
is disengaged to displa y and then decrease
the sensitivity of the alert.
• Press the gap increase button to display
and then increase the sensitivity of the
alert.
FORWARD ALERT is
displayed in the
message centre.
WARNING
Do not use in poor visibility,
specifically fog, heavy rain, spray or
snow.
Do not use on icy or slippery roads.

Adaptive cruise control (ACC)

ADVANCED EMERGENCY BRAKE
ASSIST
On vehicles fitted with Advanced Emergency
Brake Assist, brake response is improved
during emergency braking when a moving
vehicle is detected close ahead.
Advanced Emergency Brake Assist activates If
the risk of collision increases after the
FORWARD ALERT warning is displayed.
See FORWARD ALERT FUNCTION (page 164).
The brakes are automatica lly applied gently in
preparation for rapid braking (which may be
noticeable). If the brake pedal is then pressed
quickly, then braking is implemented fully,
even if the pressure on the pedal is light.
See HINTS ON DRIVING WITH ABS
(page 144).
Advanced Emergency Brake Assist is available
at speeds above approximately 7 km/h (5 mph)
and will function even if Forward Alert and
Adaptive Cruise Control are switched off. A
fault with the system will be indicated by the
warning FORWARD ALER T UNAVAILABLE
appearing in the mess age centre. Advanced
Emergency Brake Assist will not be available
until the fault is rectified.
WARNING
Advanced Emergency Brake Assist, is
an additional safety system and is not
intended to relieve the driver of the
responsibility for exer cising due care and
attention when driving.
CAUTION
The system may not react to slow
moving vehicles and will not react to
stationary vehicles or vehicles not
travelling in the same direction as your vehicle.
Advanced Emergency Brake Assist can
only improve braking performance if the
driver applies the brakes.
Warnings may not appear if the distance
to the vehicle ahead is very small or if
steering wheel and pedal movements
are large (e.g. to avoid a collision).
Advanced Emergency Brake Assist
utilises the same radar sensor as
Adaptive Cruise Control and Forward
Alert - the same limita tions of performance
apply.
See PRINCIPLE OF OPERATION (page 159).
