Tow Like a Pro: A Guide to Using GM's Advanced Trailering Technology

Hauling trailers, boats, or recreational equipment requires the right combination of vehicle capability and advanced technology. GM vehicles like the 2025 GMC Sierra 1500 come equipped with sophisticated trailering systems designed to make towing safer, easier, and more confident for drivers of all experience levels.

Modern GM trucks and SUVs offer integrated technology that takes the guesswork out of trailering. From precise hitch alignment to automated brake control, these systems work together to help you manage heavy loads with greater control and peace of mind.

Integrated Trailer Brake Controller: Your Electronic Towing Partner

The integrated trailer brake controller represents one of the most important safety advances in modern trailering. Available across the GMC Sierra 1500 lineup as standard equipment on SLE, Elevation, SLT, AT4, and Denali trims, this system integrates directly with your vehicle's antilock braking system and StabiliTrak stability control.

Unlike aftermarket brake controllers that require separate installation and calibration, the integrated system automatically coordinates your trailer's electric brakes with your vehicle's braking system. When you press the brake pedal, the controller sends the appropriate signal strength to your trailer's brakes, providing balanced stopping power across both vehicle and trailer.

The system includes trailer sway control functionality, which monitors for unwanted trailer movement and can automatically apply vehicle and trailer brakes while reducing engine power to help correct sway conditions before they become dangerous.

Hitch Guidance and Hitch View: Precision Alignment Technology

Hitch Guidance System Standard on all Sierra 1500 trims, Hitch Guidance uses dynamic guidelines displayed on your vehicle's screen to help you align your hitch ball with the trailer coupler. The system provides real-time visual guidance that adjusts as you back up, making it easier to centre your vehicle for proper connection.

Hitch View Camera Technology Available on SLE, Elevation, SLT trims and standard on AT4 and Denali models, Hitch View allows you to zoom in on the hitch area for a detailed view of the connection point. This feature enables you to see exactly how your hitch ball aligns with the trailer coupler, reducing the need for a spotter and multiple positioning attempts.

In-Vehicle Trailering App: Comprehensive Tow Management

Available on higher Sierra 1500 trims, the In-Vehicle Trailering App serves as your digital towing assistant. This integrated system provides:

• Pre-departure checklists to ensure all connections are secure
• Trailer brake controller adjustment directly through the touchscreen
• Trailer profiles that store settings for different trailers you regularly tow
• Maintenance reminders specific to trailering usage

The app integrates with your vehicle's systems to monitor trailer brake performance and provide alerts if issues are detected during your journey.

ProGrade Trailering System: Professional-Level Capability

Available on the GMC Sierra 1500 SLT trim, the ProGrade Trailering System takes towing technology to a professional level. This comprehensive package includes enhanced cooling systems, upgraded suspension components, and advanced monitoring capabilities designed for frequent heavy-duty towing applications.

The system features enhanced engine cooling, transmission cooling, and power steering cooling to maintain optimal operating temperatures even under demanding towing conditions. Upgraded suspension components help maintain vehicle stability and ride quality when carrying tongue weight and managing trailer dynamics.

Camera Technology and Visibility Enhancement

Modern GM trailering systems include multiple camera technologies to improve visibility and safety:

Auxiliary Trailer Camera Support Available across Sierra 1500 trims (except Pro), this feature allows you to connect a camera mounted on your trailer for enhanced rear visibility. The camera feed integrates directly with your vehicle's display system.

Trailering Mirrors Power-adjustable vertical trailering mirrors provide extended visibility down the sides of your trailer. Available mirrors include heated upper glass to maintain clear visibility in various weather conditions.

Max Trailering Package: Heavy-Duty Capability

The Max Trailering Package, available on SLE, Elevation, and SLT trims, includes hardware upgrades to support maximum towing capacity:

• Enhanced cooling radiator for improved heat management
• Heavy-duty rear springs to support tongue weight
• 220-amp alternator for increased electrical capacity
• Revised shock tuning optimized for towing loads

Setting Up Your Trailering System

Initial Configuration Begin by programming your trailer profile in the In-Vehicle Trailering App. Enter your trailer's weight, length, and brake type. The system will automatically adjust brake controller settings and provide appropriate safety guidelines.

Pre-Tow Inspection Use the app's checklist feature to verify all electrical connections, safety chains, and hitch security. The system will guide you through proper inspection procedures and remind you of essential safety steps.

On-Road Operation Engage Tow/Haul mode through your vehicle's drive mode selector. This setting adjusts transmission shift patterns, throttle response, and cooling system operation for optimal towing performance. The integrated brake controller will automatically coordinate braking between your vehicle and trailer.
