Mitsubishi Forklift forklift Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical issue has been detected in a core system of your Mitsubishi Forklift, demanding immediate attention. | Safely stop the forklift and consult the display or manual for specific fault details. | |
| Master Caution | AMBER | A non-critical system fault or warning has been identified by the forklift’s monitoring systems. | Review the display for more information and plan corrective action soon. | |
| Check Engine (MIL) | AMBER | The engine control unit has detected a malfunction affecting emissions or performance on your Mitsubishi Forklift. | Complete your current task, then have the engine checked by a qualified technician. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels, risking severe engine damage. | Shut down the engine immediately and check oil level and leaks before restarting. | |
| Battery / Charging | RED | The charging system is not maintaining battery voltage on your Mitsubishi Forklift. | Inspect the alternator belt and battery connections; service if needed. | |
| Coolant Temperature | RED | The engine coolant temperature is above the safe operating range. | Stop the forklift, allow the engine to cool, and check coolant level. | |
| Transmission Temp | RED | Transmission fluid temperature has exceeded safe limits, risking transmission damage. | Pause operation and let the transmission cool before continuing. | |
| Brake System | RED | A malfunction in the hydraulic or service brake system has been detected. | Stop operating and inspect brake fluid level and brake components. | |
| ABS | AMBER | The anti-lock braking system is not functioning, reducing braking control on slick surfaces. | Operate with caution and arrange for ABS diagnostics. | |
| Parking Brake | RED | The parking brake is engaged or not fully released. | Release the parking brake before driving. | |
| Low Fuel | AMBER | Fuel level is low and the forklift will soon require refueling. | Refuel at the next opportunity to avoid downtime. | |
| Glow Plug / Preheat | AMBER | The preheat system is active to assist cold starting of the diesel engine. | Wait for the light to turn off before starting the engine. | |
| DPF / Regeneration | AMBER | The diesel particulate filter requires regeneration to burn off accumulated soot. | Follow the on-screen prompts to initiate or complete regeneration. | |
| DEF / AdBlue | AMBER | The DEF (AdBlue) tank is low or there is a fault in the emissions system. | Refill with DEF or have the emissions system checked. | |
| Water in Fuel | AMBER | Water has been detected in the diesel fuel system, risking injector damage. | Drain the water separator as soon as possible. | |
| Hydraulic System | AMBER | Hydraulic oil level or pressure is outside normal range. | Inspect hydraulic fluid level and check for leaks. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature is high or oil level is low. | Allow the system to cool and check fluid levels. | |
| Engine Oil Temperature | RED | Engine oil temperature is above safe limits, risking engine damage. | Stop the engine and allow it to cool before resuming work. | |
| Air Filter | AMBER | The air filter is clogged, reducing engine efficiency. | Clean or replace the air filter promptly. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter is restricted or water separator needs draining. | Service or replace the fuel filter and drain water separator. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours. | Schedule and perform required maintenance soon. | |
| Work Lights | BLUE | Work lights are switched on for improved visibility. | No action required unless lights are not needed. | |
| Beacon / Rotating Light | AMBER | Rotating beacon is active to alert nearby personnel. | No action required unless beacon is not functioning. | |
| Overload / Capacity | RED | The load exceeds the rated capacity of your Mitsubishi Forklift. | Lower the load immediately and reassess before lifting. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum lift height or limit switch. | Do not attempt to lift further; lower as needed. | |
| Brake Fluid Level | RED | Brake fluid level is critically low, jeopardizing braking performance. | Refill brake fluid and inspect for leaks before operating. | |
| Fasten Seat Belt | AMBER | The operator seat belt is not fastened, compromising safety. | Buckle the seat belt before operating the forklift. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Oil filter blockage
What to do
Immediately shut down the Mitsubishi Forklift engine, check oil level, and inspect for leaks or faulty components before restarting.
Overload / Capacity
Common causes
- Attempting to lift a load above rated capacity
- Incorrect load positioning
- Faulty load sensor
What to do
Lower the load to within the forklift’s rated capacity and verify load weight before resuming operation.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Stop the forklift, allow it to cool, and check coolant level and radiator for obstructions before continuing use.
Brake System
Common causes
- Brake fluid leak
- Worn brake pads or shoes
- Hydraulic brake failure
What to do
Inspect the brake system thoroughly for leaks or worn parts and repair as needed before returning the Mitsubishi Forklift to service.
Battery / Charging
Common causes
- Broken alternator belt
- Faulty alternator
- Loose battery connections
What to do
Check the alternator belt and battery terminals, and replace or repair any faulty charging components.
Frequently Asked Questions
What should I do if the DPF regeneration light comes on?
Follow the on-screen instructions to complete a parked regeneration cycle and avoid interrupting the process.
Can I continue operating if the ABS light is on?
You may continue with caution, but braking performance may be reduced, especially on slippery surfaces; schedule ABS service soon.
Why does the air filter light keep coming on?
A clogged air filter is restricting airflow; clean or replace the air filter to restore engine performance.
How often should I check hydraulic oil on my Mitsubishi Forklift?
Check hydraulic oil levels daily before use, and top up as needed to maintain smooth operation.
What does the fasten seatbelt warning mean?
It indicates the operator’s seat belt is not engaged; always fasten the seat belt for safety before starting work.
