Which function is responding?
A feature name describes what it is designed to do—not a promise that every vehicle behaves identically.
An ADAS feature may inform the driver, warn about an apparent hazard, or assist with a limited steering or speed-control task. The same vehicle can offer several modes; feature names, control thresholds and availability vary by manufacturer and configuration.
Show an interpreted view or nearby-object indication, such as a parking view.
Alert the driver to a potential event, such as a lane departure or closing vehicle.
Apply a limited control action when feature conditions permit, such as selected braking or steering assistance.

Select a feature
Each feature is vehicle- and option-dependent.
Collision warning and braking
FCW warns; AEB may brake—but their sensing and operational boundaries are not identical.
May assess a rapidly closing situation and present an audible, visual or haptic warning. The driver remains responsible for braking and avoiding hazards.
May command braking in a qualifying detected scenario. Intervention timing, target classes, operating speed and driver override differ by system.
Scenario: pick the correct response model
Cruise and longitudinal assistance
Adaptive cruise control can manage a set-speed/following task in its operating domain; it does not remove driver responsibility.
Conventional cruise control maintains a selected speed; it does not, by that fact alone, adjust to a vehicle ahead. An equipped adaptive cruise control (ACC) system may adjust requested propulsion and braking to manage its selected speed and following-gap setting within specified conditions.
Usually a time-gap-related setting, not an always-fixed distance. Exact settings and units differ.
Only certain equipped versions support stopping and resuming; other versions cancel below a speed threshold or require a driver input.
A target may appear/disappear in the tracking path. Driver must remain ready when the system reaches its operating limits.
Classify the following-gap situation
With ACC active, an equipped car encounters another vehicle merging closely ahead. Which statement is sound?
Lane warnings and steering support
Lane-departure warning and lane-keeping assistance are not the same as continuous automated lane centering.
Can warn when the vehicle appears to depart a detected lane without an expected driver maneuver.
Can add a limited corrective steering or braking intervention in certain departure conditions.
Can provide more continuous steering assistance to follow a detected lane; availability, attention checks and permitted roads vary.
Lane-related features may depend on visible markings and vehicle speed, indicator/turn-signal status, steering input and feature settings. Paint condition, glare, weather and curvature can affect detection. A steady icon or the absence of a warning does not prove the camera is correctly aimed.
Recognize the feature by its output
Choose the feature that best matches each illustrative description. Names are generic; an actual owner's manual controls.
Side, rear and parking functions
Similar sensing locations can support very different warnings, views or vehicle interventions.
May alert about a tracked vehicle in a specified adjacent area. Blind-spot intervention, when equipped, is a distinct feature.
May signal a vehicle approaching across the rear travel path during a reversing maneuver.
May display a camera image or short-range object indication. Automated parking/braking functions, if equipped, are separate.
May assess driver attention using interior sensing and other signals. Feature behavior and privacy treatment vary.
One sensor does not equal one feature. An equipped corner radar could contribute to several side/rear functions, while parking-view cameras and ultrasonic sensors can serve other functions. Confirm actual equipment before diagnosis.
Match complaint to feature family
From sensor signal to vehicle response
A complete function needs more than detecting an object—it also needs vehicle context, conditions and a validated output path.
An actual system might use camera and radar data, speed/yaw/steering information, network communications, power/brake/steering controllers, driver switches and fault monitoring. Architecture differs by manufacturer: not every system has every sensor, and not every feature sends a control request.

Step 1 of 4
Limits, faults and post-service reasoning
Differentiate an operating limitation, a feature-disabled state, and evidence of a repair-related fault.
An otherwise functioning feature may be unavailable because a required signal or scene condition is not met.
A DTC, unexpected warning, damaged mounting or wrong data may require diagnosis; one symptom rarely identifies a part.
Even without a warning or DTC, OEM instructions may call for inspection, aiming, calibration, initialization or verification after certain work.
