International trucks are equipped with a variety of dashboard symbols that provide crucial information about the vehicle's status and performance. Understanding these symbols is essential for safe and efficient operation. Let's explore the meanings behind some of the most common dashboard indicators found in International trucks.

Engine Warning Lights

The engine warning light is one of the most critical indicators on your International truck's dashboard. When illuminated, it signifies that a condition within the engine, such as pressure or temperature, has reached a warning level. If this light stays on or the condition worsens, the engine may eventually derate or shut down to prevent damage. It's crucial to address this warning promptly to avoid potential engine issues.

Engine Shutdown Light

The engine shutdown light, often accompanied by a warning tone, indicates a serious problem. If you see this light, stop the truck immediately. It means that an engine condition has progressed beyond the warning level and is now critical. Some engines may automatically shut down if this occurs. To prevent further damage, turn off the engine as soon as it's safe to do so and contact your service provider.

Emission Control System Indicators

International trucks with MaxForce engines feature a Malfunction Indicator Light (MIL). This light signals an issue with the vehicle's emission control system. While you don't need to shut down the truck immediately when this light appears, it's important to have the vehicle serviced as soon as possible to maintain proper emissions control.

Exhaust System Indicators

High Exhaust System Temperature (HEST) Lamp

The HEST lamp indicates that regeneration is in progress, resulting in high exhaust temperatures. This light typically comes on occasionally and at low speeds. It's a normal condition but serves as a reminder to be cautious of your surroundings, especially when parking, due to the elevated exhaust temperature.

Diesel Particulate Filter (DPF) Light

The DPF light relates to the diesel particulate filter, which captures soot that would otherwise be released as exhaust smoke. When this light is on, you may see a message indicating that a parked regeneration is required. There are two ways to address this:

1. Drive at highway speeds for about 20 minutes to generate enough heat for the DPF to self-clean.

2. Perform a parked regeneration if highway driving isn't possible.

A flashing DPF light means the exhaust filter is nearly full, and immediate action is required to prevent power limitation and potential damage to the engine and exhaust system.

Other Important Indicators

  • ABS Warning Light: Indicates an issue with the anti-lock brake system.
  • Brake Warning Light: Signals a malfunction in the brake system.
  • Coolant Warning Light: Alerts you when the coolant level is low.
  • Diesel Exhaust Fluid (DEF) Lamp: Illuminates when the DEF level is low and needs refilling.

Dashboard Color Coding

International trucks use a color-coding system for dashboard symbols to indicate the severity of issues:

  • Red: Requires immediate attention
  • Yellow/Amber: Needs monitoring or service soon
  • Green: System functioning properly
  • Blue: Informational

Understanding these color codes can help drivers quickly assess the urgency of dashboard warnings.

By familiarizing yourself with these International truck dashboard symbols and their meanings, you can ensure safer operation and timely maintenance of your vehicle. Always consult your truck's specific manual for detailed information, as symbols may vary slightly between models.

FAQs About International Truck Dashboard Symbols

    • What should I do if multiple warning lights come on at once?
      If multiple warning lights illuminate simultaneously, it's best to safely pull over and shut down the engine. Contact your fleet manager or a service technician for guidance.
    • How often should I expect to see the DPF regeneration light?
      The frequency of DPF regeneration depends on your driving patterns. Highway drivers may see it less often than those in stop-and-go traffic. Regular highway driving can help reduce the need for parked regenerations.
    • Can I continue driving if the Check Engine light comes on?
      While you can continue driving with the Check Engine light on, it's advisable to have the issue checked as soon as possible to prevent potential damage or decreased performance.
