Door Windows System Operation

All windows can be operated individually, or by the driver’s window control switch. The operation of the windows is proportional
to the switch activation. All windows can be controlled by ‘one touch’ in an upward or downward direction. When the ‘one
touch’ operation is activated in the upwards direction ‘pinch protection‘ is enabled. If a pinch condition is detected the window
will automatically stop and travel downwards to a pre-determined position.

When the rear window ‘one touch’ operation is activated in the downward direction, the window will drop a limited way down.
This is the comfort setting to achieve optimum noise levels when vehicle is in motion with rear windows open. Further ‘one
touch’ operation will drop the window all the way down. (Only applies to vehicles post VIN R99740) The ‘one touch’ operation
to activate the upward direction will fully close the window.

Electric window operation is enabled while the ignition is in power mode 4 and 6. When the switches in the driver's door are
used to operate the passenger windows, the driver's door module outputs a related message on the LIN (local interconnect
network) bus and medium speed CAN (controller area network) bus. The passenger door module responds to the message by
operating the appropriate window. When the child lock is engaged, the rear door modules ignore inputs from the rear window
switches.
End of travel shut off

End of travel shut-off for the window motors is determined by monitoring the current draw of the motors. Each time it switches
on a window motor, the door module measures the window motor current for a preset time. The maximum value measured
within that time is stored as the switch-on current. When the window motor current next exceeds the switch-on current, the
door module assumes the window has reached the end of its travel and switches off the power supply to the window motor
even if a window switch is still being activated.
Anti-trap

The anti-trap function is enabled for window closing in both the inching and one-shot modes. If the anti-trap feature is
activated while a window is closing, the window motor is reversed for a preset period.

A Hall sensor, located in the window regulator 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 window goes back down for preset time.
In an emergency the anti-trap function can be overridden by holding the window switch in the one-shot closed position.

After the battery has been disconnected it is necessary to initialize the door window motors to be able to operate the one-shot
up function.


Windshield Component Description

The windshield, manufactured from 5mm laminated green-tinted glass is positioned to the vehicle's body by two locator pins,
one in each top corner of the windshield. This allows for centralizing movement of the windshield across the car upon fitment.
The base of the windshield carries a leaf-screen retainer. The windshield is bonded and sealed to the vehicle body aperture
using Polyurethane (PU) adhesive. The windshield finisher is a three-sided extruded flip, taped onto the inner surface of the
glass; this helps to centralize the glass in the aperture.
Two variants of windshield are available:
standard, and
heated.
Refer to: Control Components (412-01 Climate Control, Description and Operation).
Interior Mirror and Rain Sensor

The interior mirror and rain sensor mounting positions are located at the top of the windshield.
Refer to: Wipers and Washers (501-16 Wipers and Washers, Description and Operation).

Safety Belt System - Safety Belt System - Overview
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).

Activation Deactivation
NOTE: When automatic locking retractor is activated, no further webbing
can be drawn from the seatbelt retractor, prior to disengagement of the
automatic locking. This can be mistaken as a jammed seatbelt retractor
Activated by total extraction of the webbing Automatic locking retractor is deactivated by
allowing the webbing to retract until the
clicking stops (close to park position) When activated the automatic locking retractor is identified by a clicking noise
during webbing retraction When deactivated the automatic locking
retractor seatbelt changes state, from a static
seatbelt to an automatic seatbelt Seatbelt Locking Test

With the vehicle stationary and on level ground take firm hold of the seatbelt webbing (on the tongue side of the upper
seatbelt anchor) and withdraw sharply, the retractor should lock. Preventing further webbing release (repeat this test 3
times). Any seatbelt retractor which fails to lock must not be used and a new seatbelt must be installed.

Crash Signal

When the RCM outputs any of the fire signals it also outputs a crash signal to the RJB and the ECM (engine control module) on the high speed CAN. The crash signal is also hardwired to the ECM and the RJB. The instrument cluster picks up the crash signal from the high speed CAN and gateways it to the LCM (lighting control module). On receipt of the crash signal, the RJB goes into a crash mode and the ECM cuts the power supply to the fuel pump relay. In the crash mode, the RJB: Activates all of the unlock signals of the vehicle locking system, even if the vehicle is already unlocked.
Ignores all locking/superlocking inputs until it receives an unlock input, when it returns the locking system to normal
operation.
Activates the interior lamps. The interior lamps remain on permanently until they are manually switched off at the lamp
unit, or the RJB crash mode is switched off and they return to normal operation. Disables the rear window child lock input until the crash mode is switched off.
Sends a crash message to the LCM, to activate the hazard flashers. The hazard flashers remain on until cancelled by the hazard warning switch or the crash mode is switched off.
The RJB crash mode is switched off by a valid locking and unlocking cycle of the locking system.


Restraints Control Module Component Description



The RCM is installed on the top of the transmission tunnel, in line with the B pillars, and controls operation of the SRS (supplemental restraint system). The main functions of the RCM include:
Crash detection and recording
airbag and pre-tensioner firing
Self-test and system monitoring, with status indication via the airbag warning lamp and non-volatile storage of fault
information.
The RCM determines which elements of the SRS are to be deployed by using two internal areas:
