Cruise control
156

PRINCIPLE OF OPERATION
Cruise control enables the driver to maintain a
constant road speed without using the
accelerator pedal. This is particularly useful for
motorway cruising, or for any journey where a
constant speed can be maintained for a lengthy
period.
The cruise (speed) contro l system can be used
by the driver to maintain a selected vehicle
speed above 30 km/h (18 mph).
Adjustment controls on the steering wheel
allow the driver manual control of the system.
Brake operations also influence the cruise
control system.
1. SET - The speed adjustment control thumb
wheel is used to engage cruise control
initially by rolling it upw ards. It is also used
to increase ( +) or decrease ( -) the set
speed until the desired speed is obtained.
2. CANCEL - Cancels cruise control but
retains the set speed in memory.
3. RESUME - Resumes the cruise control set
speed after it ha s been cancelled.
USING CRUISE CONTROL
Setting vehicle speed
When you are travelling at the speed you
require, roll the speed adjustment control ( 1)
upwards or downwards to increase or decrease
speed.
Cruise control will engage and maintain the set
speed and you can remove your foot from the
accelerator pedal.
Note: Cruise control w ill automatically
disengage when the brake pedal is pressed or
when the vehicle speed falls below 30 km/h
(18 mph).

WARNING
Only use cruise control when
conditions are favourable, for
example, straight, dry, open roads
with light traffic.
In certain conditions, such as a steep
downhill gradient, the vehicle speed
may exceed the set cruising speed.
This is because engine braking is unable to
maintain or reduce the vehicle speed. Driver
intervention may be required.

159
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.

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.
See PRINCIPLE OF OPERATION (page 159).
See USING ACC (page 159).
See FORWARD ALERT FUNCTION
(page 164).

167
Automatic speed limiter (ASL)

PRINCIPLE OF OPERATION
ASL can be used in a situation where varying
vehicle speed is likely but a maximum speed
must not be exceeded. For example, where a
local speed limit is 80 km/h (50 mph), the set
speed could be at that limit or just under.
If ASL is not selected, cr uise control is always
available by simply rotating the thumb wheel
on the right-hand side of the steering wheel to
set a cruising speed. The ASL button allows the
driver to select betwee n cruise control and the
automatic speed limiter. The ASL can be set to
any speed between 30 km/h (18 mph) and 240
km/h (150 mph).
Note: Although ASL only operates at speeds
between 30 km/h (18 mph) and 240 km/h (150
mph), the maximum speed can be set when the
vehicle is stationary.
When ASL is selected, the warning indicator in
the instrument panel will illuminate. When the
ASL button is pressed ag ain, the light will
extinguish, ASL will be cancelled and cruise
control will be available again.
USING THE ASL
Setting a speed limit
• Press the ASL button.
• Use the thumb wheel ( 1) to set the
required speed. The message centre
display in the instru ment panel will show
the selected speed.
• The set speed can be adjusted at any time
by rotating the thumb wheel (1).
WARNINGS
Automatic Speed Limiter (ASL) set
speeds must be within local speed
restriction limits. The driver must
always ensure that a safe speed is set, taking
into account the prevailing traffic and road
conditions.
In certain conditions, such as a steep
downhill gradient, the vehicle speed
may exceed the set speed limit. This
is because engine br aking is unable to
maintain or reduce the vehicle speed. Driver
intervention may be required.

CLIMATE CONTROL (page 116).
Note: The engine oil level on V6 petrol engines,
should be checked more frequently if the
vehicle is driven for prolonged periods at high
speeds. The engine oil level on diesel and V8
petrol engines is checked automatically at all
times by the electronic dipstick.
Severe driving conditions
When a vehicle is operated in severe
conditions, more frequent attention must be
paid to servicing requirements.
Severe driving conditions include:
• Driving in dusty and/or sandy conditions.
• Driving on rough and/or muddy roads
and/or wading. •
Driving in extremely hot or cold
conditions.
• Driving in areas using road salt or other
corrosive materials.
• Towing a trailer or driving in mountainous
conditions.
Contact your Dealer/Authorised Repairer for
advice.
Emission control
Your vehicle is fitted with various items of
emission and evaporati ve control equipment,
designed to meet specific territorial
requirements. You should be aware that
unauthorised replacemen t, modification or
tampering with this equipment by an owner or
repair shop, may be unlawful and subject to
legal penalties.
In addition, engine se ttings must not be
tampered with. These have been established to
ensure that your vehicle complies with
stringent exhaust em ission regulations.
Incorrect engine settings may adversely affect
exhaust emissi ons, engine performance and
fuel consumption. The y may also cause high
temperatures, which will result in damage to
the catalytic converter and the vehicle.
Road testing dynamometers (rolling
roads)
Because your vehicle is equipped with anti-lock
brakes, it is essential that any dynamometer
testing is carried out only by a qualified person,
familiar with the dynamometer testing and
safety procedures practised by
Dealers/Authorised Repairers.
CAUTION
Ensure that you take notice of any
message centre information and
warnings relating to engi ne oil level (V8 petrol
and diesel engines only). Top-up the level
when advised to do so. See ENGINE OIL
CHECK - V8 Petrol engines (page 199).
