Can You Flat Tow A Honda Ridgeline? | The Mechanic’s Take

Yes, specific generations and configurations of the Honda Ridgeline can be flat towed, but it requires strict adherence to manufacturer guidelines.

There’s a special freedom that comes with hitting the open road in your RV, knowing your trusty daily driver is following right behind. For many adventurers, the convenience of flat towing—four wheels down—is a game-changer. When it comes to a vehicle like the Honda Ridgeline, with its unique unibody construction and often all-wheel-drive system, questions about its flat towing capability are common.

Can You Flat Tow A Honda Ridgeline? Understanding the Drivetrain.

Flat towing, sometimes called dinghy towing, means pulling a vehicle with all four of its wheels on the ground. This differs from using a tow dolly (two wheels up) or a car hauler trailer (all four wheels up). The primary concern with flat towing any automatic transmission vehicle, especially one with all-wheel drive (AWD), revolves around lubrication.

Most automatic transmissions rely on the engine running to circulate lubricating fluid. If the engine is off and the wheels are spinning the transmission components, those parts can overheat and suffer severe damage due to a lack of lubrication. This is why many manufacturers explicitly forbid flat towing.

The Honda Ridgeline, particularly its second generation (2017-present), often features an i-VTM4 AWD system. This sophisticated setup manages power distribution to all four wheels. While the first generation Ridgeline (2006-2014) was generally not recommended for flat towing, later models introduced specific procedures in their owner’s manuals that, when followed precisely, allow for this type of towing.

It’s important to recognize that a “yes” comes with significant caveats. The procedures involve specific steps to prepare the transmission and drivetrain for towing, often including running the engine periodically during long trips to ensure proper lubrication. Ignoring these steps can lead to costly transmission failure.

The Owner’s Manual: Your First and Most Reliable Guide

Before you even think about hooking up a tow bar, your Ridgeline’s owner’s manual is the definitive authority. This isn’t just a suggestion; it’s a non-negotiable step. The manual contains specific instructions for “Recreational Towing” or “Dinghy Towing” that are unique to your vehicle’s model year and drivetrain configuration.

Look for sections detailing the exact procedure: which gear to select, ignition switch position, how often to run the engine, and any distance or speed limitations. For example, some manuals might specify a maximum towing distance before the engine must be run for a certain period, or a maximum speed limit while being towed. According to the NHTSA, proper vehicle maintenance, including adherence to manufacturer towing guidelines, is critical for road safety.

These procedures are designed to mitigate the lubrication issues inherent in towing an automatic transmission with the engine off. Deviating from them risks catastrophic damage to your Ridgeline’s transmission and other drivetrain components.

Essential Preparations for Flat Towing a Ridgeline

Once you’ve confirmed your specific Ridgeline model is flat-towable and you understand the manual’s instructions, a thorough preparation routine is vital. Think of this as preparing for a long journey, not just a short hop.

• Transmission & Ignition: Follow the manual exactly. This typically involves placing the transmission in Neutral and setting the ignition to the “Accessory” (ACC) position. The ACC position unlocks the steering wheel, allowing the Ridgeline to track properly behind your tow vehicle, but it can also drain the battery over extended periods.
• Battery Disconnection: For longer trips, your manual might recommend disconnecting the Ridgeline’s battery to prevent it from draining while the ignition is in ACC. If you do this, ensure any supplemental braking system that requires battery power has its own independent power source.
• Fluid Levels: Double-check your transmission fluid, engine oil, and brake fluid levels. While the engine isn’t running, adequate fluid levels are always a baseline for vehicle health.
• Tire Pressure: Inflate all four tires on the Ridgeline to the manufacturer’s recommended pressure. Correct tire pressure ensures even wear and stable tracking.
• Lights & Signals: Ensure the Ridgeline’s brake lights, turn signals, and running lights are connected and synchronized with your tow vehicle. This is a legal requirement and a critical safety feature.

These steps are not merely suggestions; they are safeguards against mechanical failure and crucial for safe operation on public roads.

Selecting the Right Towing Equipment

Proper equipment is just as important as proper preparation. Using the wrong gear can compromise safety and cause damage to both your Ridgeline and your tow vehicle.

• Base Plate: This is a vehicle-specific bracket that bolts directly to the Ridgeline’s chassis, providing attachment points for the tow bar. It must be designed specifically for your Ridgeline’s model year to ensure a secure and safe connection.
• Tow Bar: The tow bar connects the base plate on the Ridgeline to the hitch receiver on your RV. It needs to be rated for the Ridgeline’s curb weight, plus any cargo you might have inside. Look for a non-binding tow bar, which makes connecting and disconnecting easier, especially on uneven ground.
• Safety Chains or Cables: These provide a redundant connection between the Ridgeline and the tow vehicle in case the primary tow bar fails. They should be rated for the vehicle’s weight and crossed beneath the tow bar to cradle it if it detaches.
• Supplemental Braking System: This is arguably the most critical piece of equipment after the tow bar itself. Most states require a supplemental braking system for towed vehicles exceeding a certain weight (often 1,500 to 3,000 pounds), and the Ridgeline certainly falls into that category. A proportional braking system is generally preferred, as it applies the Ridgeline’s brakes in proportion to the tow vehicle’s braking, providing smoother and safer stops.
• Wiring Harness: A dedicated wiring harness ensures that the Ridgeline’s taillights, brake lights, and turn signals operate in sync with your RV, making your towed vehicle visible and compliant with traffic laws.

Legal and Safety Considerations for Towing on Public Roads

Towing introduces a new set of dynamics to your driving experience. Understanding the legal landscape and adopting safe driving practices is vital for everyone on the road.

• Weight Limits: Always ensure your RV’s Gross Combined Weight Rating (GCWR) is not exceeded. This rating includes the weight of the RV, its cargo, and the towed Ridgeline. Overloading can severely compromise braking and handling.
• State Regulations: Towing laws vary significantly from state to state. These regulations can cover requirements for supplemental braking systems, maximum overall length of the combined vehicles, and the use of extended mirrors. It’s your responsibility to be aware of and comply with the laws in every state you travel through.
• Pre-Trip Inspection: Before every departure, perform a thorough walk-around inspection. Check all connections, confirm lights are working, ensure safety chains are properly attached, and verify the supplemental braking system is operational.
• Driving Dynamics: A towed vehicle increases your overall length and weight. This means longer stopping distances, wider turning radii, and increased fuel consumption. Drive defensively, allow extra space, and anticipate maneuvers well in advance. The RV Industry Association provides comprehensive guidelines for safe recreational vehicle operation and towing practices.

Post-Towing Checks and Maintenance

Arriving at your destination doesn’t mean the work is done. A few simple checks after each towing session help ensure the longevity of your Ridgeline.

• Reconnect Battery: If you disconnected the battery, reconnect it before attempting to start the Ridgeline.
• Fluid Check: Briefly check the transmission fluid level again, especially if you towed for a significant distance.
• Run Engine: Always run the Ridgeline’s engine for a few minutes before driving it, allowing fluids to circulate and components to warm up.
• Warning Lights: Pay attention to any dashboard warning lights that may appear.
• Inspect Equipment: Routinely inspect your tow bar, base plate, and safety chains for any signs of wear, damage, or corrosion.
• Scheduled Maintenance: If you flat tow frequently, consider more frequent transmission fluid changes than the standard schedule. The additional stress, even with proper procedures, can warrant closer attention to fluid health.

Why Flat Towing Might Not Always Be the Best Option

While flat towing offers convenience, it’s not without its drawbacks, and sometimes alternative methods are a better fit for your situation.

• Wear and Tear: Even with the engine off, the Ridgeline’s tires, suspension, and steering components are still accumulating wear and tear. Miles aren’t being added to the odometer, but the mechanical stress is present.
• Tire Wear: The tires on the towed vehicle are constantly rolling, experiencing friction and wear, just as if the vehicle were being driven.
• Limited Reversibility: Flat towing setups are generally not designed for backing up. Attempting to reverse with a flat-towed vehicle can cause severe damage to the tow bar, base plate, or the Ridgeline’s steering components.
• Alternative Towing Methods:
  • Tow Dolly: A tow dolly lifts the front two wheels off the ground while the rear wheels remain on the road. For a front-wheel-drive Ridgeline, this might be an option, but for AWD models, it usually isn’t suitable unless the rear driveshaft can be disconnected, which is often impractical.
  • Car Hauler Trailer: This method involves loading the entire Ridgeline onto a dedicated trailer, taking all four wheels off the ground. It’s the safest option as it eliminates all wear and tear on the Ridgeline and removes the need for a supplemental braking system on the towed vehicle itself. The downsides are the increased weight and length of the combined setup, requiring a more capable tow vehicle and more careful maneuvering.
