Toyota Forklift FGU25 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A major system fault has been detected on the FGU25 that may threaten safe operation. | Stop the forklift immediately and investigate the source of the warning. | |
| Check Engine (MIL) | AMBER | The engine control unit has logged a fault specific to the FGU25's fuel or emissions system. | Schedule a diagnostic check with a Toyota technician as soon as possible. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels, risking engine damage in the FGU25. | Shut down the engine immediately and inspect oil level and system for leaks. | |
| Battery / Charging | RED | The FGU25 alternator is not charging the battery, which can quickly lead to a stall. | Check battery terminals and drive belt; arrange repairs if necessary. | |
| Coolant Temperature | RED | The engine coolant temperature on the FGU25 has reached a critical level. | Stop the forklift, let the engine cool, and inspect coolant level and radiator. | |
| Brake System | RED | A malfunction in the FGU25's brake system has been detected, affecting stopping ability. | Do not operate until the brake system is inspected and repaired. | |
| Parking Brake | AMBER | The parking brake is engaged on the FGU25, preventing movement. | Release the parking brake before attempting to drive. | |
| Seat Belt | AMBER | The operator seat belt is not fastened while the FGU25 is running. | Securely fasten your seat belt before operating. | |
| Low Fuel | AMBER | The FGU25's fuel level is nearly empty and will soon run out. | Refuel the forklift before continuing operation. | |
| Service / Hour Meter | AMBER | The FGU25 has reached a scheduled maintenance interval based on engine hours. | Arrange required service to maintain warranty and performance. | |
| Work Lights | GREEN | Work lights are switched on, illuminating the FGU25's operating area. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The overhead beacon is active, signaling forklift operation in the area. | No action needed unless beacon is malfunctioning. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is low, which can affect lift performance on the FGU25. | Check hydraulic oil reservoir and top up as needed. | |
| Air Filter | AMBER | The FGU25's air filter is clogged, restricting engine airflow. | Inspect and replace the air filter for optimal performance. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter has detected water or is clogged on the FGU25. | Drain water separator or replace the fuel filter as soon as possible. | |
| Overload / Capacity | RED | The load on the FGU25 exceeds rated lifting capacity, risking tip-over. | Lower the load immediately and check load weight. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum safe lift height on the FGU25. | Do not attempt to raise the mast further. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump malfunction
- Oil filter blockage
What to do
Immediately stop the FGU25, check oil level, and inspect for leaks or clogged filters. Only restart after resolving the underlying issue.
Brake System
Common causes
- Low brake fluid
- Worn brake pads or shoes
- Hydraulic brake line leak
What to do
Do not operate the FGU25 until the brake system is thoroughly checked and repaired by a qualified technician.
Coolant Temperature
Common causes
- Low coolant level
- Radiator or hose leak
- Faulty thermostat
What to do
Turn off the FGU25 engine, allow it to cool, and top up coolant if needed. Inspect for leaks and have the cooling system serviced if overheating persists.
Overload / Capacity
Common causes
- Load exceeds forklift's rated capacity
- Incorrect load positioning
- Improper use of attachments
What to do
Lower the load to a safe level, verify it does not exceed the FGU25's specifications, and ensure proper handling techniques are used.
Battery / Charging
Common causes
- Loose or corroded battery terminals
- Broken alternator belt
- Faulty alternator
What to do
Inspect battery connections and alternator belt on the FGU25; repair or replace faulty components to restore charging.
Frequently Asked Questions
What should I do if the Master Warning light appears on my FGU25?
Immediately stop the forklift in a safe area and consult the operator's manual or a Toyota technician to diagnose the specific fault.
How often should I service my Toyota FGU25 based on the hour meter?
Follow the maintenance intervals listed in your FGU25 manual, typically every 250 engine hours for basic service tasks.
Why does the hydraulic oil light come on during heavy lifting?
This indicates low hydraulic oil or pressure, which can occur if the oil level is low or there is a leak; check and top up as needed.
Can I drive with the parking brake light on?
No, always release the parking brake before moving the FGU25 to avoid unnecessary wear and reduced performance.
What does the overload light mean on my FGU25?
It means the load on your forks is too heavy or improperly positioned; lower the load and verify it is within the forklift's rated capacity.
