| Battery / Charging | RED | The charging system is not maintaining battery voltage, affecting electrical systems. | Inspect the alternator and battery connections before further use. | |
| Coolant Temperature | RED | Coolant temperature has exceeded the safe operating range for your Hyster forklift. | Stop the engine and allow it to cool; check coolant levels. | |
| Transmission Temp | RED | Transmission fluid temperature is critically high, risking component failure. | Cease operation and let the transmission cool down. | |
| Brake System | RED | A malfunction in the forklift's brake system has been detected. | Do not operate until the brakes are inspected and repaired. | |
| ABS | AMBER | The anti-lock braking system is not functioning, affecting braking stability. | Drive cautiously and arrange for ABS diagnostics. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on your Hyster forklift. | Release the parking brake before driving. | |
| Tire Pressure (TPMS) | AMBER | One or more tires are below recommended pressure, impacting load stability. | Check and inflate tires to specified pressures. | |
| Seat Belt | AMBER | The operator seat belt is not fastened, disabling certain forklift functions. | Secure your seat belt before operation. | |
| Glow Plug / Preheat | AMBER | The engine preheat system is active for cold starting conditions. | Wait for the light to turn off before starting the engine. | |
| DPF / Regeneration | AMBER | The diesel particulate filter is regenerating to burn off soot build-up. | Keep the engine running until the light goes out. | |
| DEF / AdBlue | AMBER | DEF fluid level is low, which may limit engine performance soon. | Top up the DEF tank at your next opportunity. | |
| Water in Fuel | AMBER | Water contamination has been detected in the fuel system. | Drain the water separator promptly. | |
| Low Fuel | AMBER | Fuel level is low and the forklift will soon require refueling. | Refuel at the next break to avoid downtime. | |
| High Beam | BLUE | The forklift's high beam work lights are switched on. | Switch off high beams if not needed. | |
| Hydraulic System | AMBER | A hydraulic system issue is detected, affecting lift or tilt functions. | Inspect hydraulic fluid level and check for leaks. | |
| Reduced Power (Limp Mode) | AMBER | The forklift has entered limp mode to protect the engine or transmission. | Arrange for immediate service to restore full power. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or condition is below optimal for safe operation. | Check and top up hydraulic oil as needed. | |
| Engine Oil Temperature | RED | Engine oil temperature has risen to unsafe levels. | Stop the engine and allow it to cool before checking oil. | |
| Air Filter | AMBER | The air filter is clogged, restricting airflow to the engine. | Clean or replace the air filter soon. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter is clogged or water separator needs draining. | Replace filter or drain separator per the manual. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on operating hours. | Book service to maintain forklift reliability. | |
| Work Lights | GREEN | Work area lights are currently activated. | Switch off when adequate light is available. | |
| Beacon / Rotating Light | AMBER | The safety beacon is turned on to signal forklift operation. | Ensure beacon is functional during operation. | |
| Overload / Capacity | RED | The forklift is overloaded beyond rated lifting capacity. | Lower the load immediately to prevent tipping. | |
| Low Oil Level | AMBER | Oil level in the engine or hydraulics is below recommended. | Check and replenish oil before continuing. | |
| Brake Fluid Level | AMBER | Brake fluid is low, which may reduce braking performance. | Top up brake fluid and inspect for leaks. | |
| Door Open | AMBER | A cab or engine compartment door is not securely closed. | Close all doors before driving. | |
| High Exhaust Temp (HEST) | AMBER | Exhaust temperature is high, usually during active DPF regeneration. | Keep area clear of flammable materials. |

Frequently Asked Questions
What should I do if the DPF regeneration light stays on?
Allow the forklift to complete its regeneration cycle by keeping the engine running at operating temperature until the light turns off.
Why does the seat belt light prevent the forklift from moving?
For safety, Hyster forklifts disable certain functions unless the seat belt is fastened to protect the operator.
How often should I check fluid levels on my Hyster forklift?
Check engine oil, hydraulic oil, coolant, and brake fluid daily before starting your shift.
What does it mean if the hydraulic system warning comes on?
It indicates a possible hydraulic leak, low fluid, or system fault; inspect fluid levels and hoses immediately.
Can I continue working if the master caution light is illuminated?
You may continue operation for minor issues, but check the display for details and address the problem as soon as possible.
How do I reset the service/hour meter light?
After completing scheduled maintenance, use the instrument panel controls to reset the service indicator according to the Hyster manual.
