Pricing was recently adjusted, so now is a smart time to act to secure this capable, off-road-ready truck before inventory changes. Wireless Apple CarPlay and Android Auto keep your apps, navigation and messages mirrored to the Sierras display without the hassle of cords, so you stay connected on the road. Forward collision mitigation constantly scans ahead and steps in with protective measures if a sudden stop appears likely, helping to reduce the chance or severity of a frontal impact. Front pedestrian impact prevention helps the truck detect and track people crossing the roadway and can take preventive action if a collision becomes probable, adding an extra layer of safety in busy areas. An integrated mobile hotspot lets passengers access the internet through the trucks private connection, so everyone can stream, navigate, or work without draining phone data. A rear camera provides a clear view behind the vehicle when reversing, making parking and hitching safer and more convenient by revealing obstacles you might not see otherwise. Lane departure prevention watches lane position and can intervene to help keep you centered, reducing the chance of unintentional drift and improving peace of mind on long drives. Rear collision mitigation monitors whats behind the truck and prepares the vehicle and occupants if a rear impact looks imminent, helping to lessen potential damage or injury. Adaptive cruise control with traffic stop-go maintains a safe following distance and can bring the truck to a stop and resume in traffic, making highway driving and congestion far less stressful. Predictive brake assist readies the braking system when closing distances shorten too quickly, so your brakes respond more effectively when you need to stop fast.
