Safety Features
The 2026 GMC Sierra 3500HD boasts an array of advanced safety features designed to protect occupants and enhance driving confidence.
Automatic Emergency Braking (AEB)
AEB utilizes sensors to detect potential collisions and automatically applies the brakes if the driver fails to react. It can help prevent or mitigate rear-end accidents, especially in urban areas or during heavy traffic.
Lane Departure Warning (LDW)
LDW monitors lane markings and alerts the driver with audible and visual signals if the vehicle unintentionally drifts out of its lane. This feature is particularly useful during long highway drives or inattention.
Forward Collision Alert (FCA)
FCA uses radar or camera sensors to scan the road ahead and warn the driver of an impending collision with a vehicle or object. It provides ample time for the driver to take evasive action or brake.
Adaptive Cruise Control (ACC)
ACC automatically adjusts the vehicle’s speed to maintain a safe following distance from the vehicle ahead. It helps reduce driver fatigue and improves overall driving comfort, especially during extended highway travel.
Blind Spot Monitoring (BSM)
BSM utilizes sensors to detect vehicles in the driver’s blind spots and alerts them with visual indicators on the side mirrors. This feature is particularly helpful when changing lanes or merging into traffic.
Rear Cross-Traffic Alert (RCTA)
RCTA uses sensors to monitor the area behind the vehicle and warns the driver of approaching vehicles when reversing. This feature is beneficial when backing out of parking spaces or driveways.
StabiliTrak Electronic Stability Control (ESC)
ESC detects loss of vehicle control and automatically adjusts the brakes and engine power to help maintain stability. It prevents skids and rollovers, especially in slippery or adverse road conditions.
Teen Driver System
The Teen Driver System allows parents to set limits and monitor their teen drivers’ behavior behind the wheel. It includes features like speed limit warnings, seat belt reminders, and restricted audio volume.
HD Surround Vision Camera System
This system provides a 360-degree view of the vehicle’s surroundings, making it easier to maneuver in tight spaces, park, and avoid obstacles. It offers a clear view of the vehicle’s blind spots and enhances overall visibility.
