The Fusion’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The LaCrosse’s rear power window switches have to be held the entire time to close them fully.
If the windows are left down on the Fusion the driver can raise them all using the keyless remote; on a hot day the driver can lower the windows. The driver of the LaCrosse can only operate the windows from inside the vehicle, with the ignition on.
In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Fusion SE/Titanium’s exterior keypad. The LaCrosse doesn’t offer an exterior keypad entry system, and its OnStar ® can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.
The Fusion’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The LaCrosse’s manually variable intermittent wipers have to be constantly adjusted. The Fusion SE/Titanium’s optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.
While driving with high beams on, sensitive light sensors available for the Fusion SE/Titanium detect other vehicles which could be blinded and automatically switch to low beams. The LaCrosse doesn’t offer automatic dimming high beams.
The Fusion SE/Titanium’s optional Active Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The LaCrosse doesn’t offer an automated parking system.
