How to Call the Tolling Knob of the SUV

If you’re driving an SUV—especially one built for off-roading, towing, or rugged terrain—you may have noticed a small knob or dial labeled something like “Toll,” “Towing,” “Height,” or “Suspension.” This is commonly referred to as the tolling knob, though it may go by different names depending on the manufacturer. While the term “tolling” isn’t standard across all brands, it generally refers to a control that adjusts the vehicle’s suspension system, ride height, or towing mode.

In this comprehensive guide, you’ll learn exactly how to call the tolling knob of the SUV—meaning how to locate, identify, and operate it safely and effectively. Whether you’re preparing to tow a trailer, driving over rocky trails, or simply want to optimize your SUV’s performance, mastering this feature can make a big difference. We’ll cover everything from understanding what the knob does, where to find it, step-by-step operation, safety tips, troubleshooting, and maintenance.

By the end of this guide, you’ll feel confident using your SUV’s tolling knob like a pro—no mechanic required.

What Is the Tolling Knob?

Before we dive into how to use it, let’s clarify what the tolling knob actually is. Despite the slightly unusual name, the “tolling knob” is a real feature found in many modern SUVs, especially those designed for versatility—like the Toyota Land Cruiser, Ford Explorer, Jeep Grand Cherokee, or Land Rover models.

The tolling knob typically controls the electronic suspension system or adaptive ride height. It allows drivers to adjust how high or low the vehicle sits, which can improve stability, ground clearance, fuel efficiency, or towing capacity. In some vehicles, it also activates special driving modes such as “Tow/Haul,” “Off-Road,” or “Snow.”

For example:
– In a Jeep Grand Cherokee, the knob might let you raise the suspension for off-road driving.
– In a Ford Expedition, it could activate the “Tow/Haul” mode to optimize transmission and braking when pulling a heavy load.
– In a Land Rover Defender, it may adjust air suspension to lower the vehicle for easier entry or raise it for rough terrain.

So while the term “tolling” might not appear in your owner’s manual, the function is very real—and very useful.

Why Use the Tolling Knob?

You might be wondering: “Do I really need to use this knob?” The short answer is: yes, if you want to get the most out of your SUV.

Here’s why using the tolling knob matters:

• Improved Safety: Adjusting ride height or activating towing mode can enhance vehicle stability, especially when carrying heavy loads or driving on uneven surfaces.
• Better Performance: The right setting can optimize engine response, transmission shifting, and braking efficiency.
• Enhanced Comfort: Lowering the suspension at highway speeds can reduce wind resistance and improve ride smoothness.
• Increased Ground Clearance: Raising the vehicle helps avoid scraping the undercarriage on rocks, curbs, or steep driveways.
• Fuel Efficiency: Some modes reduce drag or adjust aerodynamics, which can slightly improve gas mileage.

In short, the tolling knob is like a “smart switch” that tailors your SUV’s behavior to match your driving needs. Ignoring it means missing out on key features designed to make your ride safer and more capable.

Step 1: Locate the Tolling Knob

The first step in calling the tolling knob is finding it. Unfortunately, there’s no universal location—it varies by make and model. But here’s where to look:

Common Locations

• Center Console: Near the gear shifter or between the front seats. This is the most common spot.
• Dashboard: Lower section, often near climate controls or infotainment systems.
• Overhead Console: Above the rearview mirror, especially in luxury SUVs with advanced suspension.
• Driver’s Side Kick Panel: Less common, but some vehicles hide controls near the footwell.

How to Identify It

Look for a rotary dial or push-button switch with labels like:
– “TOW/HAUL”
– “HEIGHT”
– “SUSPENSION”
– “OFF-ROAD”
– “MODE”
– “AUTO” / “LOW” / “HIGH”

It may also have icons—like a car with arrows pointing up and down, or a trailer symbol.

Check the Owner’s Manual

If you’re still unsure, consult your vehicle’s owner’s manual. Search for terms like “suspension control,” “ride height adjustment,” or “driving modes.” The manual will show a diagram and explain the function clearly.

> 💡 Pro Tip: Take a photo of the knob and its surroundings. This helps when searching online forums or asking technicians for help.

Step 2: Understand the Settings

Once you’ve found the knob, the next step is understanding what each position does. Most tolling knobs have 3–5 settings. Here’s a breakdown of common modes:

Normal / Auto Mode

This is the default setting for everyday driving. The system automatically adjusts suspension or ride height based on speed, load, and road conditions. Use this for city driving, highways, and light loads.

Low / Entry Mode

Lowers the vehicle to make it easier to get in and out. Often used when parked or at low speeds. Some SUVs activate this automatically when doors are unlocked.

High / Off-Road Mode

Raises the suspension to increase ground clearance. Ideal for dirt roads, trails, or deep snow. May reduce top speed for safety.

Tow / Haul Mode

Optimizes the transmission, throttle response, and braking for towing heavy loads. May also adjust suspension stiffness. Look for a trailer icon.

Sport / Performance Mode

Firms up the suspension for better handling and cornering. Often lowers the vehicle slightly for improved aerodynamics.

Snow / Ice Mode

Adjusts traction control and throttle sensitivity for slippery conditions. May raise the vehicle slightly to avoid snow buildup.

> 🚗 Example: In a Toyota 4Runner, turning the knob to “HIGH” raises the suspension by about 1.5 inches for off-road use. In a Ford F-150 (SUV variant), “TOW/HAUL” mode delays upshifts and enhances engine braking.

Step 3: How to Call the Tolling Knob (Step-by-Step)

Now that you know what the knob does and where it is, here’s how to operate it safely and correctly.

Step 3.1: Ensure the Vehicle Is Ready

• Start the engine. Most systems require the vehicle to be on (or in accessory mode) to function.
• Make sure the vehicle is on level ground. Avoid adjusting height on slopes.
• If towing, ensure the trailer is properly connected and the weight is distributed evenly.

Step 3.2: Turn the Knob to Desired Mode

• Rotate the knob slowly to the setting you need (e.g., “HIGH” for off-road, “TOW” for hauling).
• You may hear a faint whirring sound as the suspension adjusts—this is normal.
• Wait 10–30 seconds for the system to complete the adjustment. Don’t drive until it’s done.

Step 3.3: Confirm the Change

• Check the dashboard for confirmation lights or messages (e.g., “OFF-ROAD MODE ACTIVE”).
• Look outside: the vehicle should visibly rise or lower depending on the setting.
• Test gently: drive slowly for a short distance to feel the difference in ride quality.

Step 3.4: Return to Normal When Done

• Once you’re back on paved roads or no longer towing, return the knob to “NORMAL” or “AUTO.”
• This helps preserve suspension components and improves fuel efficiency.
• Some systems revert automatically after a set time or speed.

> ⚠️ Safety Note: Never adjust the tolling knob while driving at high speeds. Sudden changes in ride height can affect handling and stability.

Step 4: Use the Right Mode for the Situation

Using the tolling knob effectively means matching the setting to your driving conditions. Here’s a quick reference guide:

City Driving

Use Normal or Auto mode. Keeps the ride comfortable and fuel-efficient.

Highway Driving

Stick with Normal. Some SUVs automatically lower slightly at high speeds for better aerodynamics.

Off-Roading

Switch to High or Off-Road mode. Increases clearance and may engage 4WD or locking differentials.

Towing a Trailer

Activate Tow/Haul mode. Improves braking, reduces trailer sway, and protects the transmission.

Snow or Ice

Use Snow or Low mode if available. Enhances traction and prevents slipping.

Parking in Tight Spaces

Engage Entry or Low mode to lower the vehicle for easier access.

> 🌧️ Real-World Example: Sarah drives a Jeep Grand Cherokee. When she heads to the mountains for a weekend trip, she turns the knob to “OFF-ROAD” before hitting the dirt trails. On the way back, she switches to “TOW/HAUL” because she’s pulling a small camper. Once home, she returns it to “AUTO” for daily commuting.

Step 5: Safety Tips and Best Practices

Using the tolling knob is simple, but safety should always come first. Follow these best practices:

• Don’t adjust while moving fast: Only change modes when parked or driving below 20 mph.
• Watch for obstacles: When raising the vehicle, ensure there’s enough clearance above (e.g., garage doors).
• Don’t overload: The tolling knob doesn’t increase your vehicle’s weight capacity. Follow manufacturer limits.
• Use gradually: Avoid rapid switching between modes. Let the system stabilize.
• Listen for warnings: If the dashboard shows a suspension warning light, stop using the knob and get it checked.
• Keep it clean: Dust and dirt can jam the knob. Wipe it gently with a dry cloth.

> 🛠️ Maintenance Tip: Every few months, cycle through all the modes (when safe) to keep the mechanism lubricated and functional.
