Rear view camera
152

PRINCIPLE OF OPERATION
The system provides a rear view image to
assist in reversing the vehicle.
The camera is positioned centrally and
unobtrusively, just above the rear license plate.
When reverse gear (R) is selected, the rear
view camera displays a wide-angle, colour view
from the rear of the vehicle, displayed on the
touch-screen. The camera display also incorporates graphic
overlays to aid the driver in assessing vehicle
direction, width and pr
oximity to surrounding
objects. These are detailed under Camera
overlays later in this section.
The camera display on the touch-screen has
priority over the parki ng aid display. To view
the parking aid display instead, touch the
touch-screen.
If a parking aid sensor is activated with the
camera in use, a corresponding red shaded
area will appear on the camera display to
identify which sensor has been activated.
To cancel the rear view camera display at any
time, touch the touch-screen.
The camera image will not be displayed when
any of the following apply:
• D is selected and the vehicle speed is
greater than 16 km/h (10 mph).
• D is selected for longer than 2 seconds and
the vehicle speed is less than 16 km/h
(10 mph).
WARNINGS
It remains the driver's responsibility
to detect obstacles and estimate the
vehicle's distance from them when
reversing. Some ov erhanging objects or
barriers, which could possibly cause damage
to the vehicle, may not be detected by the
camera.
Always be vigilant when reversing.

Message centre information displays
Message Warning IndicatorPriority
Indicator Meaning
CRUISE OVERRIDE None None Driver is pressing the accelerator pedal,
overriding Cruise Control function.
Message will disappear when accelerator
pedal is released and Cruise Control
speed is resumed.
CRUISE CANCELLED None None Driver has cancelled cruise control or is
braking.
CRUISE NOT AVAILABLE None None Cruise C ontrol or Adaptive Cruise Control
malfunction.

Adaptive cruise control (ACC)
160

Setting the speed
Accelerate as normal until the required speed is
reached.
Rotate the speed adjustment control upwards
(+) to store the vehicle speed in the memory
and engage the system.
The set speed will be displayed on the message
centre (e.g. SETSPEED 80 KM/H (50 MPH) ).
Changing the speed
There are three ways to change the set speed:
•Accelerate or brake to the desired speed
then rotate the speed adjustment control
upwards ( +).
• Increase or decrease the speed by rotating
the speed adjustment control upwards ( +)
or downwards ( -), until the required set
speed is shown on the message centre.
The vehicle speed will gradually adjust to
the selected speed.
• Increase or decrease the speed in steps of
2 km/h (1 mph) by rotating the speed
adjustment control upwards (+) or
downwards ( -) briefly until the desired
speed is obtained.
ACC operates between approximately 30 km/h
and 180 km/h (18 mph and 112 mph)
dependent on the c ountry specification.
Set speeds outside th is range will not be
captured. The ACC may apply the brakes to slow down
the vehicle to the new set speed. The new set
speed will be displayed on the message centre
until ACC is cancelled.
Follow mode gap settings
Once a set speed has been selected, the driver
can release the accelerator and the set road
speed will be maintained.
When a vehicle ahead enters the same lane or
a slower vehicle is ahead in the same lane, the
vehicle speed will be adjusted automatically
until the gap to the vehicle ahead corresponds
to the default gap setting (gap level 3). The
vehicle is now in
follow mode.
The amber warning indicator in the
instrument panel will be
illuminated.
The message centre will display the gap set.
E97091
WARNING
When in follow mode, the vehicle will
not decelerate automatically to a stop,
nor will the vehicle always decelerate
quickly enough to avoid a collision, without
driver intervention.

Adaptive cruise control (ACC)

The vehicle will then maintain the constant time
gap to the vehicle ahead until:
•The vehicle ahead accelerates to a speed
above the set speed.
• The vehicle ahead moves out of lane or out
of view.
• A new gap distance is set.
If necessary, the vehicle brakes will be
automatically applied to slow the vehicle to
maintain the gap to the vehicle in front.
The maximum braking which is applied by the
ACC system is limited and can be overridden by
the driver applying the brakes, if required.
Note: Driver braking will cancel ACC.
If the ACC system predicts that its maximum
braking level will not be sufficient, then an
audible warning will sound while the ACC
continues to brake. DRIVER INTERVENE will be
displayed on the message centre. The driver
should take immediate action.
When in follow mode, the vehicle will
automatically return to the set speed when the
road ahead is clear, for instance when:
• The vehicle in front accelerates or changes
lane.
• The driver changes lane to either side or
enters an exit lane.
The driver should intervene if appropriate.
Changing the follow mode set gap
The gap from the vehicle ahead can be
decreased or increased by rolling the
thumbwheel on the stee ring wheel. Four gap
settings are available and the selected gap
setting will be displaye d on the message centre
when either ACC button is pressed. Each gap level is indicated by an
additional
chevron in front of th e vehicle icon in the
message centre (one chevron (gap level 1)
being the shortest, four chevrons (gap level 4)
being the longest). A fter the ignition is
switched on, the default gap (gap level 3) will
be automatically selected ready for ACC
operation.
Note: When the ignition is switched off, the
gap setting will revert to the default setting
(gap level 3) when switched on again.
Note: It is the driver’s responsibility to select a
gap appropriate to the driving conditions.
Overriding the speed and follow mode
The set speed and gap ca n be overridden by
pressing the accelerator pedal when cruising at
constant speed or in follow mode. If the vehicle
is in follow mode, the instrument warning
indicator will go out when the ACC is
overridden by the driver using the accelerator
and CRUISE OVERRIDE will be displayed on
the message centre. When the accelerator is
released the ACC functi on will operate again
and vehicle speed will decrease to the set
speed, or a lower spee d if follow mode is
active.
WARNING
Whenever the driver is overriding the
ACC by depressing the accelerator
pedal, the ACC will not automatically
apply the brakes to ma intain separation from
any vehicle ahead.

Adaptive cruise control (ACC)

Automatic low speed switch off
If the speed of the vehicle decreases below
30 km/h (18 mph), the ACC system will be
automatically switched off and the instrument
warning indicator will go out.
If the brakes were being applied by the ACC
system, they will be slowly released.
This will be accompanied by an audible
warning, and DRIVER INTERVENE will be
displayed on the message centre. The driver
must take control.
Automatic switch off
ACC will disengage, but not clear the memory
when;
• the CANCEL button ( 3) is pressed
• the brake pedal is pressed
• Neutral ( N), Park ( P) or Reverse ( R) gear
positions are selected
• Dynamic Stability Control activates.
ACC will disengage, and clear the memory
when;
• the ignition system is switched off
• maximum vehicle speed is reached
• a fault occurs in the ACC system.
Resuming the speed and follow mode
By pressing the RESUME button (4) after ACC
has been cancelled, for example, after braking,
the ACC will become active again provided that
the set speed memory has not been erased.
The original set speed will be resumed (unless
a vehicle ahead causes the follow mode to
become active) and the set speed will be
displayed in the message centre for four
seconds.
Hints on driving with ACC
The system acts by regulating the speed of the
vehicle using engine c ontrol and the brakes.
Gear changes may occur in response to
deceleration or acceleration whilst in ACC.
ACC is not a collision avoidance system.
However, during some situations the system
may provide the driver with an indication that
intervention is required.
An audible alarm will sound, accompanied by
the message DRIVER INTERVENE if the ACC
detects:
• A failure has occurred whilst the system is
active
• That using maximum ACC braking only is
not sufficient.
Note: ACC operates when the gear selector
lever is in position S or D.
Note: When engaged, the accelerator pedal
rests in the raised position. Fully release the
pedal to allow normal ACC operation.
Note: When braking is applied by the ACC, the
vehicle brake lamps will be switched on
although the brake pedal will not move.
CAUTION
RESUME should only be used if the
driver is aware of the set speed and
intends to return to it.

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.
