Re-heating of the refrigerated air is contro lled by the time that the water valve is open (i.e. not energised) over a six secon d
interval. The duty cycle of the water valve, the time open / time closed, is controlled by the A/CCM.
Maximum heating demand will cause the water valve to be fu lly open (not energised) to allow maximum coolant flow
through the heater matrix.
At Maximum cooling, the water va lve will be fully closed (energised) to prevent hot (engine temperature) coolant entering
the heater circuit; the pump however will continue to circulate coolant through both the heater matrix and water valve
bypass.
The water valve defaults open when the ignition is OFF.
Under engine stall conditions, when ignition is ON, the water valve will be open.
Water Pump Assembly
Located in the same area as the water valve, the water pump continually circulates coolant through the heater matrix
except when the conditions below apply:
The engine coolant is below 16°C. The ignition is OFF. Under engine stall conditions, when ignition is ON. Control panel OFF
Non return valves
The heater bypass hose has a non-return valve, located between the engine feed and return hoses. The valve prevents the
water pump from recirculating coolant fro m the heater at low engine speeds.
The flow indicator arrow embossed on the valve bo dy MUST point towards the coolant header tank.
CAUTION: Coolant flow will be compromi sed if either valve is fitted incorrectly. Observe the correct direction.
A second non-return valve is located betw een the water pump and water valve. This valve prevents hot coolant from flowing
into the heater with the engine switched off. The flow indicator arrow MUST point towards the water pump.
Heater feed and return hoses
The heater feed and return hoses are connected to the engine feed and return hoses by 'Quick-Fit' connection unions. The
feed hose has a Norma R20 connector and the return hose a Norma push and seal connector. The coolant system bleed
joints have Cobra clamps. All remaining hose connections have spring band hose clamps.
The engine feed hose is connected to the engine bypass hous ing and the engine return hose is connected to the engine
water pump.
Clamp Identification

The functi
on of the parking aid is to prov
ide an audible warning to the driver of the distance to obstacles near the rear
bumper of the vehicle when parking or travelling at a slow sp eed. The system provides an assistance to the driver when
parking in order to help avoid collision with obstacles.
The sensor range at the rear of the vehicl e should be 1.8 meters. This should extend the full width of the rear bumper and
reduce to 50 cm at the vehicle co rners. The vertical range is adequate to protec t the highest and lowest points of the rear of
the vehicle. The system will detect curbs with heights of at least 18 cm. Obstacles, such as curbs, that are low enough to
pass under the vehicle until they make contact with the tires will not be detected.
The system activates a specific speaker with a tone signifying the distance to the obstacle. The tone consists of a beep and
defined space ratio which varies depending on the calculated distance. When the distance to the obstacle is less than 20 cm
the speaker tone is continuous.
The parking aid is continuously in operation, unless towing wh en the system automatically switches off. If the reverse aid
develops a fault the tone will sound continuously for three seconds when the igni tion is switched on or the reverse gear is
selected.
The parking aid system comprises of:
a
module mounted in the batte
ry junction box (BJB).
fou
r rear bumper mounted sensors which have a 90° angled electrical connector.
an audible speaker, moun

ted on
the rear parcel shelf.

Each front and rear door consists of a welded, mild steel inner frame and an outer panel. The outer panel is welded to the
waist rail and cheater of the inner frame, then bonded and clinched to fo rm the door assembly. Cosmetic PVC bead is
applied to all clinch joints. Sp onge rubber seals are mounted on the doors. Inte rnal insulation is provided by a foam water
shedder attached to the door by double-sided adhesive tape.
The door aperture B/C posts are reinforced over their full height to fully satisfy all forthcoming European and Federal side
impact legislation. The hood consists of one piece inner and outer panels clinched and bonded together, with cosmetic bead
PVC sealant applied to all clinch joints. Th e hood pivots at the front on two hinges each secured by bolts to the hood front
underside and the BIW front upper crossmem ber. Two gas struts secured to the hood by pivot pins and snap-on couplings,
support the hood in the open position. A full width insulating pad is secured by screws to the underside of the hood. A
sponge rubber tubular seal is mounted tran sversely towards the front of the hood underside. The trunk lid is of similar
construction to the hood, consisting of inner and outer pa nels clinched and bonded together and PVC bead sealed.
Incorporating a removable moulded liner and two trunk illuminati on lights, the trunk lid is supported when open, by two gas
struts, each secured to the inner wheel arch and trunk hinge by snap fittin gs. For some markets, a warning triangle is
attached to a bracket on the trunk lid underside and is retained in the open position by a rubber block.

support bracket and seat adjuster mechanis ms. Seat switchpacks are installed on the outboard side of driver and passenger
seats and control modules are installed in the base of each seat . The standard rear seat is of fixed, bench type with full
width removable cushion. For certain mark ets, two individual rear seats are available as an option on long wheelbase
models. Both type s of rear seat are available with th ermostatically controlled heating of the cushion and sq uab. Individual
rear seats are electrically adjustable fo r squab re cline (via cushion fore and af t movement), head restraint height and
lumbar support. Separate motors provide ad justment of each seat cushion and head restraint and an electrically driven air
compressor provides variation of lumbar support. Seat adjustment is controlled via switches installed on a panel in an
extension to the centre console.Both the driver and front pass enger seat are secured to the vehicle floor at four points.
Interior Trim
The one-piece door casings are trimmed in UEV to match the seating, with wood veneer at the waistline and a carpet insert
at the front lower corner. Each casing is secured to the door inner panel by fir tree fastener s along the lower section, two
armrest fixings at the centre and veneer panel dowels and fixings at the top. The armrests which are common to front and
rear doors, are trimmed in matc hing leather or UEV according to specification. Switchpacks dedicated to driver and front or
rear passenger, are incorporated in the ar mrests. A speaker is installed in the lower section of each door and a tweeter is
incorporated behind each interior door handle escutcheon. where premium ICE is fitted, the front tweeters are installed in
the upper A posts. On each side, a graine d UEV finisher trimmed to match the head lining is secured to the 'A' post and
cantrail by fir tree fasteners locating in BIW apertures. Th e upper 'D' post finisher is trimmed and secured in the same
manner. The single piece'B' post finishers, also finished in grained matching UEV, each have a front seat belt exit aperture
and are secured to the BIW by four spring clips and two fir tree fasteners. The one-piece headlining consists of a 6mm thick
polyurethane foam membrane covered with suede effect knitted polyester. The headlining is secured to the BIW roof by
