Overview

The windshield is manufactured from laminated green-tinted glass with two variants of windshield being available: standard
and heated.

The rear window is manufactured from toughened green-tinted glass. The heated rear window grid-wire and antennas are
incorporated in the rear window. There are two variants of rear window dependant on the TV antenna specification.

The door windows are manufactured from green-tinted toughened glass. The driver and passenger windows are electrically
operated; the rear glass sections in the rear doors are fixed units. Door windows can be operated individually, or by the driver's
window control switch. An anti-trap function is included that stops the window's travel when an obstacle is detected in the in
the window's path.

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).

Rear Window

The rear window, manufactured from toughened 4mm 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 the centralizing movement of the windshield across the car upon
fitment. The window is bonded and sealed to the vehicle body aperture using PU adhesive. The window finisher is a
three-sided extruded flip, taped onto the inner surface of the glass; this helps to centralize the glass in the aperture.

The heated rear window grid wire and antennas are incorporated in the rear window. There are two derivatives of rear window
dependant on the TV antenna specification.
Refer to: Video System (415-01, Description and Operation).

Door Windows

The door windows are manufactured from 4.85mm green-tinted toughened glass. The driver and passenger windows are
electrically operated, and are raised and lowered by a cable mechanism; the rear glass sections in the rear doors are fixed
units.

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. The driver window can be controlled by 'one touch' in an upward or downward direction. When the 'one
touch' operation is activated in the upwards direction an anti-trap sensor is automatically checked prior to the window closing.
If the anti-trap sensor is inoperative the window will not close. When the anti-trap sensor detects an obstacle in the window's
path, the upward travel of the window will automatically cease. Downward travel of the window will begin and then stop when a
preset time has elapsed.
