| Engine Oil Pressure | RED | Activates when oil pressure drops below safe operating level in the T6.175 engine. | Stop engine immediately and check oil level and pressure. | |
| Battery / Charging | RED | Indicates the T6.175's charging system is not supplying voltage to the battery. | Check alternator belt and battery connections; replace battery if needed. | |
| Coolant Temperature | RED | Warns that engine coolant temperature in the T6.175 is critically high. | Stop engine, let cool, and check coolant level and fan operation. | |
| Transmission Temp | AMBER | Indicates the T6.175's transmission oil temperature is above normal operating range. | Reduce load and shift to a lower gear; allow transmission to cool. | |
| Brake System | RED | Alerts to a fault in the T6.175's braking system, such as low fluid or worn pads. | Stop tractor safely and inspect brake fluid level and lines. | |
| Parking Brake | AMBER | Illuminates when the parking brake on the T6.175 is engaged or partially engaged. | Release parking brake fully before moving. | |
| Glow Plug / Preheat | AMBER | Shows that the glow plugs are actively preheating the T6.175 engine for cold starts. | Wait until light turns off before cranking the engine. | |
| DPF / Regeneration | AMBER | Indicates that the Diesel Particulate Filter in the T6.175 is actively regenerating to clear soot. | Allow regeneration to complete; do not interrupt unless unsafe. | |
| DEF / AdBlue | AMBER | Lights up when the T6.175's DEF level is low or the system detects a fault. | Refill DEF tank with approved fluid; if light remains, service the system. | |
| Water in Fuel | AMBER | Detects water contamination in the T6.175's fuel system, typically in the separator. | Drain water from fuel filter/separator immediately. | |
| Low Fuel | AMBER | Warns that the T6.175's fuel level is critically low. | Refill fuel tank as soon as possible to avoid engine starvation. | |
| High Beam | BLUE | Illuminates when the high beam headlights on the T6.175 are turned on. | Dim high beams when approaching other vehicles. | |
| Power Steering (EPS) | RED | Indicates a fault in the T6.175's electric power steering system, reducing assist. | Drive slowly to dealer; steering effort will increase. | |
| Hydraulic System | AMBER | Alerts to a problem in the T6.175's hydraulic system, such as low oil level or filter blockage. | Check hydraulic oil level and condition; service filter if needed. | |
| PTO Engaged | GREEN | Shows that the Power Take-Off on the T6.175 is engaged and rotating. | Disengage PTO before servicing driven equipment. | |
| Differential Lock | GREEN | Indicates the rear differential lock on the T6.175 is engaged for improved traction. | Disengage diff lock when turning on hard surfaces. | |
| Work Lights | GREEN | Glows when the T6.175's auxiliary work lights are turned on. | Turn off work lights when not needed to conserve battery. | |
| Beacon / Rotating Light | GREEN | Indicates the rotating beacon on the T6.175 is active, increasing visibility. | Ensure beacon is used when operating on public roads. | |
| Service / Hour Meter | AMBER | Reminds that the T6.175 is due for scheduled maintenance based on engine hours. | Perform required service per operator's manual interval. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Stop the T6.175 immediately, let engine cool, then check coolant level and radiator fins. If persistent, inspect water pump and thermostat.
Transmission Overheat
Common causes
- Excessive load
- Low transmission oil level
- Clogged cooler
What to do
Reduce load and shift to lower gear on the T6.175; allow transmission to cool. Check oil level and external cooler for debris.
DPF Clogged
Common causes
- Frequent low-load operation
- Failure to complete regen
- Poor fuel quality
What to do
Perform a stationary regeneration via the T6.175's dash menu. If unsuccessful, dealer service may be required.
Low DEF Quality
Common causes
- Using non-approved DEF
- Contaminated DEF tank
- DEF heater failure
What to do
Drain and replace DEF with fresh, approved fluid in the T6.175. If light persists, inspect the DEF system components.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Hydraulic filter clogged
- Pump failure
What to do
Check hydraulic oil level and top off if low on the T6.175. Replace hydraulic filter; if still no operation, consult dealer for pump diagnosis.
Frequently Asked Questions
What does the DPF regeneration light mean on my T6.175?
It means the Diesel Particulate Filter is burning off soot to prevent clogging. You can continue normal operation, but avoid interrupting the process unless safety requires it.
Why is the DEF warning light on?
The DEF fluid level is low or the system has a fault. Refill with approved DEF. If the light stays on, have the system checked to avoid reduced engine power.
Can I drive with the master caution light on?
Yes, but reduce load and monitor other warnings. The T6.175 will still operate, but schedule service soon to avoid bigger issues.
How do I reset the service hour meter?
After performing required maintenance, the T6.174's service reminder can be reset through the instrument cluster menu—refer to the operator's manual for the specific sequence.
What should I do if the transmission temperature light comes on?
Reduce engine speed and shift to a lower gear to allow the T6.175's transmission to cool. If the light stays on, stop and check transmission oil level.
Why does the glow plug light come on when starting?
The T6.175's glow plugs preheat the engine cylinders for cold starts. Wait until the light goes out before cranking.
