Front Door: Description and Operation
Doors are common to both coupe and convertible, with a frameless glass system, dual door-mounted seals and demountable hinges with separate multi-stage check arms. The door casings and top rolls are UEV trimmed with cloth or ambla (Leather center pads - some markets) center pads and integral pockets are attached to the inner panels by plastic studs and retainers and a large dowel. The top rolls are integral with the door casings and trimmed to match the upper fascia. A leather trimmed armrest attached to each door casing by plastic fixings, is secured to the door by a screw passed through a pull cup into a bracket. An inset maple or burr walnut veneer switch pack is held in position by a single screw and captive nut.
Each comprise inner and outer panels, clinched and bonded together to form a door assembly. Both panels incorporate extensions spot welded together to form a cheater assembly and a PVC sealant is applied in cosmetic bead form to all clinch joints.
Both the door assembly and separate outer panel are available as service items.
A dual, joint-less EPDM sponge seal is installed on each door together with a water shedder and separate vacuum formed speaker cup.
Upper and lower door hinges and multi-stage check arms require no lubrication throughout vehicle life.
The colour-keyed exterior door handles each have an integrated switch for glass drop on opening. Additionally, the driver's door handle has an integrated key barrel. The cheater is formed by the door mirror base and a black injection moulded inner cheater. The cheater seal is integral with the secondary door seal. Tweeters are fitted in the inner cheater as part of the premium in-car entertainment option. Each door has a combined rearguard/puddle lamp mounted in the door pocket casing.
Both the driver and passenger door incorporate Door Control Modules (DDM & PDM) which are connected to the SCP network and control the raising and lowering of the window glass, locking and security, puddle lamp and door mirror movement and heating functions. A drive-away door locking function incorporated in the DDM & PDM software is activated when the transmission is taken out of Park or Neutral position.
Adjustment of driver and passenger door mirrors including memory functions is controlled by the driver door switchpack through each door module. Door mirror heating is controlled via the rear windshield heating switch on the air conditioning control panel. Electrochromic mirrors available as an option are automatically heated at very low ambient temperatures. A mirror fold back function enabling the door mirrors to fold back against the body/glass when parking the car, is featured for some markets.
Dipping of the passenger door mirror when reverse gear is selected is also featured on some vehicles/markets. Dipping is either 7 degrees in a downward direction, bottom of travel or 5 seconds dependent upon which condition is satisfied first. When the gear selector is moved from reverse the door mirror will return to the original position.
