Power Windows

POWER WINDOWS







The power window operation on the E53 is similar to previous systems. Features of the system include:
- Control of the front and rear door window motors is carried out directly by the GM.
- One-touch operation in both directions on all four windows.
- Gable type window regulator used for all windows.
- Anti-trap detection is provided by the pressure sensitive finger guard
- Push/pull window switches
- The rear window switches located in the rear doors can be deactivated by the pressing child lock out switch in the center console.
- Convenience closing/opening of the windows from the driver's lock cylinder or convenience opening only from the FZV remote key (FZV operation can be owner customized with the Car Memory Function).
- Window operation with the ignition switched off until a door is opened or 16 minutes has elapsed after the key is switched off.
- Window load switching is through relays integral of the GM for rear windows and in the respective door switch block modules for the front windows. The current draw is monitored for end limit position. The maximum run time for the window motors is limited to 8 seconds. This allows the motors to be switched off if the end limit load sensing fails.
