| Transmission Temp | AMBER | Transmission oil temperature is high on the T5.110; often due to heavy load or low oil level. | Reduce load or shift to a lower gear; check transmission oil level when cool. | |
| Brake System | RED | A fault in the T5.110's brake system has been detected; braking performance may be compromised. | Do not operate; inspect brake fluid level and lines; contact a dealer. | |
| Parking Brake | AMBER | The parking brake is engaged on the T5.110; reminder to release before driving. | Release the parking brake before operating the tractor. | |
| Glow Plug / Preheat | AMBER | Glow plugs are active or a preheat fault exists on the T5.110; wait for the light to turn off before starting. | If light stays on, have the glow plug system checked by a technician. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on your T5.110 needs active regeneration; high exhaust temperature will occur. | Follow prompts on the display; operate at higher engine speed until regeneration completes. | |
| DEF / AdBlue | AMBER | Diesel exhaust fluid level is low or quality is poor on the T5.110; engine power may be reduced soon. | Refill with DEF grade per manual; if light persists, check for system faults. | |
| Water in Fuel | AMBER | Water has accumulated in the fuel filter/separator of your T5.110; drain to prevent injector damage. | Drain the fuel/water separator located near the fuel filter. | |
| Low Fuel | AMBER | Fuel level is low on the T5.110; risk of running out and air entering the fuel system. | Refuel as soon as possible to avoid priming issues. | |
| High Beam | BLUE | The high beam headlights are active on the T5.110; use on dark fields only. | Dim when approaching other vehicles or working near roads. | |
| Hydraulic System | AMBER | A fault in the hydraulic system of the T5.110 is detected; implement functionality may be affected. | Check hydraulic oil level and filter; avoid heavy use until serviced. | |
| Air Filter | AMBER | Engine air filter restriction is high on the T5.110; engine performance and fuel economy will drop. | Replace or clean the air filter element as specified in the manual. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due on your T5.110 based on engine hours; service is required. | Perform the nearest service interval tasks (oil, filters, etc.) per the operator's manual. | |
| Work Lights | GREEN | The work lights are turned on for field operations on the T5.110. | Turn off when not needed to conserve battery. | |
| Differential Lock | GREEN | The differential lock is engaged on the T5.110 for increased traction in slippery conditions. | Disengage when turning or on firm ground to avoid driveline stress. | |
| PTO Engaged | GREEN | The power take-off is now engaged on the T5.110; implement may rotate. | Ensure all safety guards are in place before leaving the seat. | |
| Seat Belt | AMBER | The seat belt is not fastened on the T5.110; the operator should buckle up. | Fasten seat belt before operating the tractor. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Blocked radiator
- Faulty thermostat
What to do
On the T5.110, stop the engine immediately and allow it to cool. Check the coolant reservoir and radiator fins for debris; if low, refill with proper coolant after engine cools. If recurring, inspect the fan belt and water pump at your New Holland dealer.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
On the T5.110, shut off the engine immediately. Check oil dipstick and add oil if low; if full but light stays on, do not restart. Have the oil pressure sensor and pump inspected by a technician.
DPF Filter Clogged
Common causes
- Frequent short operations
- Failed regeneration
- Poor fuel quality
What to do
For the T5.110, attempt a parked regeneration via the display (if equipped). If unsuccessful, the DPF may need professional cleaning or replacement at a New Holland dealer. Avoid idling for long periods.
DEF System Fault
Common causes
- Low DEF level
- Contaminated DEF
- Heater or sensor failure
What to do
On the T5.110, refill with clean DEF from a sealed container. If the light remains, the system may require a dealer diagnostic to clear fault codes and restore full power.
Transmission Overheating
Common causes
- Overloading the tractor
- Low transmission oil
- Cooler blockage
What to do
On the T5.110, reduce load or shift to a lower gear immediately. Stop the tractor and allow the transmission to cool. Check the oil level when cold; if low, add the recommended hydraulic/transmission oil. Have the cooler checked for debris.
Frequently Asked Questions
What should I do if the master warning light comes on while operating my T5.110?
Stop the tractor safely as soon as possible and consult the operator's manual for the specific fault code. Many issues require dealer service; continued operation can cause damage.
Why is the DPF regeneration light flashing and the engine power reduced on my T5.110?
Flashing indicates a regeneration is required but conditions are not met (e.g., low engine speed). Drive at higher RPM (above 1500) and load for 20-30 minutes; if it persists, a stationary regeneration via the display may be needed.
How do I reset the service (hour meter) warning light on my T5.110?
After performing the required maintenance, the warning can be reset via the instrument panel or display. Refer to the operator's manual; typically, hold the trip reset button while turning the key to 'on'.
The check engine light is on but the tractor runs fine. Can I continue working?
Yellow check engine light indicates a non-critical fault, but continued operation may lead to reduced power or emission issues. Have the fault code read as soon as possible; avoid heavy loads until checked.
What does a blinking water-in-fuel light mean on the T5.110?
A blinking light indicates the water separator is full and needs draining immediately. Drain the bowl located under the fuel filter; failure to do so can inject water into the fuel system, causing damage.
My T5.110 won't start and the glow plug light stays on. What's wrong?
The glow plug system may be faulty. Try turning the key to preheat (wait for the light to go out) then start. If the light remains on, have the glow plugs and relay checked by a technician.
