Roof opening panel System Operation

Operation of the roof opening panel is controlled by the roof opening panel control module, which is integral with the motor.
The control module receives inputs from the CJB, which provides an 'open' or 'close' signal for remote handset operation, and
an 'enable' signal when the vehicle enters power mode 6.

The control module also receives a vehicle speed signal from the ABS module. The vehicle speed signal is used by the control
module to calibrate the anti-trap feature.

If the battery is disconnected, or the power supply is interrupted while the roof opening panel is in a partially open position,
the motor and control module will need to be calibrated to restore full functionality. To recalibrate:
1. Switch ignition on.
2. Press the front of the switch, so the roof opening panel is the tilt position, and then release the switch.
3. Press the front of the switch and hold for thirty seconds.
4. After thirty seconds the roof opening panel will begin to move. Keep the front of the switch pressed until the roof
opening panel has fully opened and then closed.
5. Once the open/close cycle has completed and the roof opening panel has stopped moving, release the switch.
6. The roof opening panel can now be operated as normal.

Drain hoses are connected to the front and rear corners of the roof opening panel frame. The drain hoses are located inside of
the cabin on the 'A' and 'D' post pillars to allow water, which has collected in the frame, to escape. One-way valves fitted to
the end of each drain hose, prevent the ingress of dirt and moisture.

Rear window sunblind

The powered rear window sunblind is operated through a switch in the roof console. Power to the sunblind motor is provided by
a pair of relays located in the CJB when the vehicle enters power mode 4. The sunblind motor is located beneath the rear parcel
shelf and is supplied as a sealed unit with the sunblind mechanism.

If the battery is disconnected or a replacement sunblind is fitted, the motor will require re-calibrating. To re-calibrate the
motor the sunblind should be powered through two-full cycles of movement.



Roof opening panel, motor Component Description

The roof opening panel motor has a worm drive which drives a gear in the cast housing attached to the end of the motor. The
gear has a small pinion gear attached to the outer part of its spindle. The pinion engages with two cables to form a rack and
pinion drive. Rotation of the motor turns the pinion which in turn drives the cables in the required direction.

The two cables are attached either side of the pinion. One end of each cable is attached to the guide; the opposite end of
each cable is held in position on the pinion by a metal insert in the frame. The cables run in channels, in the panel frame to
the guides. As the panel is closed the cables are pushed through channels in the front of the frame. The displaced cable is
guided into a further two channels in the frame, which protect the cable and prevent it from snagging. The cables
manufactured from rigid spring steel can pull as well as push the panel along the guides.

The motor contains a micro-switch and Hall effect sensor. Signals received from these components enable the control module
to calculate the exact position of the roof opening panel. The Hall effect sensor is also responsible for the operation of the
anti-trap function.

If the anti-trap feature is activated while the roof opening panel is closing, the panel is reversed for 200mm or as far as
possible. The Hall effect sensor, located in the motor, monitors the speed of the motor and if the speed decreases below a set
threshold, indicating an obstruction, the power feed to the motor is reversed so the panel goes back. In an emergency the
anti-trap function can be overridden by holding the switch in the closed position.

Roof opening panel, control module

The roof opening panel control module is integrated within the motor. The control module receives inputs from the CJB, which
provides an 'open' or 'close' signal for remote handset operation, and an 'enable' signal when the vehicle enters power mode 6.

The control module also contains the algorithm for the anti-trap system and receives a vehicle speed signal from the ABS
module. The vehicle speed signal is used by the control module to calibrate the anti-trap feature.

Description and Operation
Authoring Template
OVERVIEW Published: 11-May-2011
A three point safety belt is fitted to all seating positions. Each safety belt retractor incorporates an emergency locking feature.
The emergency locking retractor incorporates 2 mechanical inertia devices. One inertia device activates if the safety belt is
subjected to a sharp pull. The second inertia device activates if the vehicle is subject to a sudden deceleration or is on a
severe incline.

North American Specification (NAS) safety belt retractors also include an automatic locking feature. The Automatic Locking
Retractor (ALR) is fitted to all passenger seating positions and allows the safety belt to be tensioned to aid the safe fitment
of child or booster seats. For additional information, refer to the Owners Handbook.

NAS vehicles are also fitted with a belt tension sensor on the front passenger seat. The belt tension sensor is incorporated
into the seat belt lower anchorage and is attached to the seat frame by an M10 Torx head bolt. The belt tension sensor forms
part of the SRS (supplemental restraint system) occupancy detection and classification feature.

The center rear safety belt features a mini-buckle lower anchorage. The mini-buckle is disengaged by inserting a suitable tool
into the small aperture on the front face of the housing.

To aid the fitment of child seats, 3 tethers are located on the rear parcel shelf. Each tether is attached to the parcel shelf with
an M10 Torx head bolt.

A safety belt warning indicator is located in the instrument cluster to remind front seat passengers to fasten their safety belts.
The warning indicator will illuminate if the safety belt of an occupied front seat is not fastened.
Refer to: Instrument Cluster (413-01, Description and Operation).

hills and in adverse camber conditions, when parked on a steep incline or driveway or two wheels on a high curb
Web sense system - A webbing motion sensor, which locks when the seatbelt webbing is extracted suddenly

Description and Operation

OVERVIEW


WARNING: All pyrotechnic devices are dangerous. Before performing any procedures on any pyrotechnic device, read all
information contained within the Standard Workshop Practices section of this manual.
Refer to: Standard Workshop Practices (100-00 General Information, Description and Operation).
The SRS (supplemental restraint system) provides additional protection for the vehicle occupants in certain impact conditions.
The system is controlled by the RCM (restraints control module), which is mounted beneath the floor console. The system
includes twin stage drivers and front passenger airbags.
The RCM receives inputs from various sensors around the vehicle and determines which, if any, airbags should be deployed.
The SRS features an occupant detection system. The occupant detection system comprises a mat fitted inside the front passenger seat. By monitoring the condition of the mat, the RCM can determine if the front passenger seat is occupied. It uses this information to determine which airbags to deploy in the event of an impact. This information is also used to illuminate the
safety belt instrument cluster warning lamp if the front passenger seat is occupied and the safety belt is not engaged.

North American Specification (NAS) vehicles also feature an occupant classification system. The occupant classification system
comprises a control module, pressure pad and safety belt tension sensor. The system can determine the size and weight of the
front seat passenger. This information is transmitted to the RCM over the high speed CAN (controller area network) bus. The RCM uses this information to help determine which airbags to deploy in the event of an impact.
