BLIND SPOT MONITOR
The Blind Spot Monitor (BSM) system
monitors a zone that covers the area adjacent
to the vehicle, that is not easily visible by the
driver and is designed to identify any object
overtaking the vehicle. Th e system uses a radar
on each side of the vehicle to identify any
overtaking vehicl e/object within the blind spot
area of the vehicle, while disregarding other
objects which may be stati onary or travelling in
the opposite direction, etc.
The radar monitors the ar ea extending from the
exterior mirror rearwards, to approximately 7
metres (23 feet) behind the rear wheels, and up
to 2.5 metres (8.2 feet) from the side of the
vehicle (the wi dth of a typical carriageway
lane).
Note: This radar sensor is approved in all RTTE
countries.
Note: The system covers an area of a fixed lane
width. If the lanes are narrower than a typical
carriageway lane, objects travelling in
non-adjacent lanes may be detected.
BSM automatically switches on and becomes
active when the vehicle is travelling at greater
than 16 km/h (10 mph) in a forward drive gear.
When the system initiates, it performs a
self-check, during which the warning icons in
the mirrors illuminate alternately for a short
period of time.
WARNINGS
The Blind Spot Monitor (BSM)
system is a supplement to, not a
replacement for, a safe driving style
and use of the exterior and rear-view mirrors.
It remains the driver's re sponsibility to detect
other vehicles, and their relative distance and
speed, when deciding whet her or not it is safe
to change lanes.
Please note that BSM may not be able
to give adequate wa rning of vehicles
approaching very quickly from behind
or vehicles that are be ing overtaken rapidly.
The radar sensors may be impaired
by rain, snow or road spray. This may
affect the sy stem's ability to reliably
detect a vehicle/object wi thin the blind spot. In
such conditions, take extra care when
changing lanes.
BSM may not be able to detect all
vehicles and may also detect objects,
such as roadside barriers, etc.
CAUTIONS
Ensure that the warning indicators in the
exterior mirrors are not obscured by
stickers or other objects.
Do not attach stickers or objects to the
rear bumpers, that may interfere with
the radar sensors.

BSM is designed to work most effectively when
driving on multi-lane highways.
If an object is identified by the system as being
an overtaking vehicle/object, an amber
warning icon ( 1) illuminates in the relevant
exterior mirror, to alert the driver that there is a
potential hazard in the vehicle's blind spot and
therefore, that a lane change might be
dangerous.
Note: If an overtaking vehicle is detected on
both sides of the vehicle simultaneously, the
warning icons in both mirrors will illuminate.
Note: BSM is automatically turned off when
reverse ( R) gear is selected, when the vehicle is
in park ( P), the vehicle is travelling below
16 km/h (10 mph) and also when the electrical
connector for the trailer socket is plugged in on
vehicles with a factory-fitted towing bracket.
When in these conditions, an amber warning
indicator within the exterior mirror is
displayed.Sensor blockage
The BSM system will automatically disable if
either of the sensors become completely
obscured, an amber wa rning indicator dot (2)
is displayed in the exterior mirror and the
message BSM sensor blocked appears in the
message centre.
Note: Blockage testing is only initiated when
vehicle speed is above 32 km/h (20 mph) and
will take at least two minutes of accumulated
time travelling above th is speed, to determine
that the sensor is blocked.
If the sensors become blocked, then please
check that there is nothing obscuring the rear
bumper and that it is cl ear from ice, frost and
dirt.
System fault
If a fault with one of the radar sensors is
detected, an amber warn ing indicator dot is
displayed in the exterior mirror and the
message BSM not available is displayed in the
message centre.
Note: Even if the detected fault only affects the
radar sensor on one side of the vehicle, the
whole system is disabled. If the fault is
temporary, the system will operate correctly
once the engine has been switched off and then
on again.
If a fault in the system occurs, consult your
Dealer/Authorised Repairer.

Adaptive cruise control (ACC)

PRINCIPLE OF OPERATION
The Adaptive Cruise Control (ACC) system is
designed to aid the driver to maintain a gap
from the vehicle ahead or a set road speed if
there is no slower vehicle ahead. The system is
intended to provide enhanced operation of the
vehicle when following other vehicles which
are in the same lane and travelling in the same
direction.
The ACC system uses a radar sensor, which
projects a beam directly forward of the vehicle
to detect objects ahead.
The radar sensor is m ounted centrally behind
the bumper cover above the cooling aperture,
to provide a clear view forward for the radar
beam.
USING ACC
The system is operated by adjustment controls
mounted on the steering wh eel. The driver can
also intervene at any time by use of the brake
or accelerator pedals. The steering wheel
adjustment controls operate as follows:
1. SET - Rotate the thumbwheel upwards ( +)
or downwards ( -), to increase or decrease
speed, until the desire d speed is achieved.
2. Gap increase or decr ease. Four settings
available by adjusting the thumb wheel.
3. CANCEL - Cancels but retains the set
speed in memory.
4. RESUME - Resumes the set speed after it
has been cancelled.
WARNING
ACC is not a collision warning or
avoidance system. Additionally, ACC
will not react to:
• Stationary or slow moving vehicles below
10 km/h (6 mph).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane.
CAUTION
Only use ACC when conditions are
favourable (i.e. main roads with free
flowing traffic).
Do not use in poor visibility, specifically
fog, heavy rain, spray or snow.
E94163
Do not use on icy or slippery roads.
It is the drivers re sponsibility to stay
alert, drive safely and be in control of the
vehicle at all times.
Keep the front of the vehicle free from
dirt, metal badges or objects, including
vehicle front protectors, which may
prevent the sensor from operating.
Do not use ACC when entering or
leaving a motorway.
CAUTION

Detection beam issues
Detection issues can occur:
1.When driving on a different line to the
vehicle in front.
2. When a vehicle edges into your lane. The
vehicle will only be detected once it has
moved fully into your lane.
3. There may be issues with the detection of
vehicles in front when going into and
coming out of a bend.
In these cases ACC may brake late or
unexpectedly. The driver should stay alert and
intervene if necessary.
ACC malfunction
If a malfunction occurs during operation of the
system in cruise or follow modes, the ACC
system will switch off a nd cannot be used until
the fault is cleared. The message DRIVER
INTERVENE appears briefly and is then
replaced by the message CRUISE NOT
AVAILABLE . If malfunction of the 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 the
ACC system in any mode.
Accumulations of dirt, snow or ice on the
sensor or cover may inhibit ACC operation.
Fitting of a vehicle front protector or metallised
badges may also affect ACC operation.
The ACC system relies on its radar to detect
objects and constantly scans ahead. If the
radar detects no objects ahead in ACC or follow
mode , then the ACC will be deactivated, the
audible alarm sounds and the message
DRIVER INTERVENE displays briefly. The
message ACC SENSOR BLOCKED will then be
displayed.
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 inac tive, e.g. on initial
starting or with the ACC system switched off,
the message ACC SENSOR BLOCKED will be
displayed.
Tyres other than those recommended may
have different sizes. This can affect the correct
operation of the ACC.1

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.

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.
