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.

MESSAGE CENTRE INFORMATION MESSAGES
MessageMeaning
CRUISE OVERRIDE 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 Driver has cancelle d cruise control or is braking.
CRUISE NOT AVAILABLE Cruise control or Adaptive
Cruise Control malfunction.
DRIVER INTERVENE Action by the driver to apply the brakes is required.
SETSPEED XXX KM/H Speed set fo r Adaptive Cruise Control.
GAP Set the distance (time gap).
RADAR SENSOR BLOCKED Clean the front of the vehicle in the area of the sensor unit (the sensor
is mounted centrally behind the
bumper cover above the cooling
aperture).
This message may also appear under the following conditions:
If stone chip protect ion has been applied.
On rural roads with few roadside objects.
In heavy rain.
FORWARD ALERT OFF Forward alert feature has been switched off.
WARNING: A warning will not be given for objects detected in
the vehicle’s path of travel.
FORWARD ALERT Forward Alert feature has been switched on or the setting changed. A
warning will be given for objects detected in the vehicle path of travel.
A longer gap indicates that the system will warn when detected objects
are further away than the previous setting.
Action by the driver to ap ply the brakes is required.
FORWARD ALERT UNAVAILABLE Advanced emergency brake assist
and Forward Alert functions are
unavailable.

Safety in the garageFuel system
Poisonous fluids
Fluids used in motor vehicles are poisonous
and should not be consumed or brought into
contact with open wounds. These include;
battery acid, antifreeze, brake, clutch and
power steering fluid, petrol, diesel, engine oil
and windscreen washer additives.
For your own safety, always read and obey all
instructions printed on labels and containers.
Used engine oil
Prolonged contact with engine oil may cause
serious skin disorders, including dermatitis
and cancer of the skin. Always wash
thoroughly after contact.
It is illegal to pollute drains, water
courses or soil. Use authorised
waste disposal site s to dispose of
used oil and toxic chemicals.
WARNINGS
If the vehicle has been driven
recently, do not touch exhaust and
cooling system components until the
engine has cooled.
Never leave the engi ne running in an
unventilated area - exhaust gases are
poisonous and extremely dangerous.
Do not work beneath the vehicle with
the wheel changing jack as the only
means of support.
Keep your hands and clothing away
from drive belts, pulleys and fans.
Some fans may continue to operate
after the engi ne has stopped.
Remove metal wrist bands and
jewellery, before working in the
engine compartment.
Do not touch electrical leads or
components while the engine is
running, or with the starter switch
turned on.
Do not allow tools or metal parts of
the vehicle to make contact with the
battery leads or terminals.WARNINGS
Under no circumstances should any
part of the fuel system be dismantled
or replaced by anyone other than a
suitably qualified vehicle technician. Failure to
comply with this instruct ion, may result in fuel
spillage with a consequent serious risk of fire.
Ensure sparks and naked lights are
kept away from the engine
compartment.
Wear protective cl othing, including,
where practicable, gloves made from
an impervious material.

Maintenance

Topping up the coolant
Top-up to the upper level indicator mark
located on the side of the expansion tank. Use
only a 50% mix of water and antifreeze to
specification WSS M97B44 (coloured orange)
Extended Life Coolant.
Note: In an emergency - and only if the
approved antifreeze is unavailable - top-up the
cooling system with clea n water, but be aware
of the resultant reduction in frost protection.
Do not top-up or refill with conventional
antifreeze formulations . If in doubt consult a
qualified technician.
Ensure the cap is tightened fully after top-up is
completed by turning the cap until the ratchet
cap clicks.
Antifreeze
Antifreeze contains important corrosion
inhibitors. The antifreeze content of the coolant
must be maintained at 50% ± 5% all year round
(not just in cold conditions). To ensure that the
anti-corrosion properties of the coolant are
retained, the antifreeze content should be
checked once a year and completely renewed
every ten years, regardless of distance
travelled. Failure to do so may cause corrosion
of the radiator and engine components.
The specific gravity of a 50% antifreeze
solution at 20°C (68°F) is 1.068 and protects
against frost down to -40°C (-40°F).
Use antifreeze to specification WSS M97B44
(coloured orange) Extended Life Coolant.
WARNINGS
Never remove the filler cap when the
engine is hot - escaping steam or
scalding water coul d cause serious
personal injury.
Antifreeze is highly inflammable. Do
not allow antifreeze to come into
contact with naked flames or other
sources of ignition (e.g. a hot engine) - a fire
may result.
Unscrew the filler cap slowly,
allowing the pressure to escape
before removing completely.
CAUTION
When travelling in territories where the
water supply contains salt, always
ensure you carry a supply of fresh (rain or
distilled) water. Topping up with salt water will
cause serious e ngine damage.
WARNINGS
Antifreeze is poisonous and can be
fatal if swallowed - keep containers
sealed and out of the reach of
children. If accident al consumption is
suspected, seek medical attention
immediately.
If the fluid comes into contact with
the skin or eyes, rinse immediately
with plenty of water.
CAUTIONS
The use of non-approved antifreeze will
have an adverse effect on the engine
cooling system and therefore engine
durability.
Antifreeze will damage painted surfaces;
soak up any spillage with an absorbent
cloth immediately and wash the area with a
mixture of car shampoo and water.
