Which component monitors obstructions for the Express Up feature?

• A. Window sensor
• B. Pressure sensor
• C. Light sensor
• D. Temperature sensor

Answer: (A)

Express Up includes a safety feature that stops the window if something blocks its path. The component responsible for detecting that blockage is the window sensor, which monitors the window’s movement and signaling when travel is impeded or when full closure is reached. If the sensor detects abnormal resistance or an obstruction, the system stops the window to prevent injury and may reverse.

The other sensors listed don’t play a role in detecting obstructions for window closure: a pressure sensor handles forces in other systems, a light sensor deals with visibility-related tasks, and a temperature sensor is used for climate control. So the window sensor is the one tied to ensuring safe, obstructed-free operation of the Express Up feature.
