New Holland T6.195 Dash Warning Lights: Symbols and Meanings

Quick answer: These dashboard warning lights follow the ISO 2575 international standard. A red symbol means stop the machine and check immediately, amber or yellow means service soon, and green or blue symbols are normal status indicators. Each symbol below is explained with its meaning, the most likely cause, and the recommended action.

The New Holland T6.195 instrument cluster is designed to monitor engine, transmission, and hydraulic systems in real time. It alerts the operator to conditions such as high coolant temperature, low DEF level, and DPF regeneration status, ensuring optimal performance and longevity.

How to read the colors: Red warns of a critical condition requiring immediate shutdown; amber indicates a pending issue or service requirement; green/blue confirms normal operation or an active system like PTO or work lights.

New Holland T6.195 Warning Light Symbols

SymbolNameColorWhat it meansWhat to do
Master Warning (Stop)REDIndicates a critical engine or safety fault detected on the T6.195, requiring immediate engine stop.Safely stop the tractor and consult the operator's manual for the specific fault code.
Master CautionAMBERWarns of a non-critical system anomaly on the T6.195, such as a sensor reading out of range.Check the message center for details and schedule service soon.
Check Engine (MIL)AMBERThe engine control unit on the T6.195 has detected an emission or performance issue.Reduce load and contact a New Holland dealer for diagnostics.
Engine Oil PressureREDEngine oil pressure has dropped below safe level for the T6.195's 6.7L engine.Immediately shut down the engine and check oil level and pressure sensor.
Battery / ChargingREDThe alternator on the T6.195 is not charging the battery properly.Check alternator belt and connections; if persists, replace battery or alternator.
Coolant TemperatureREDEngine coolant temperature on the T6.195 exceeds safe operating range.Stop the engine, allow to cool, inspect coolant level and radiator for blockages.
ATTransmission TempAMBERThe T6.195's CVT or dual-clutch transmission oil temperature is high, risking reduced performance.Reduce load and let the transmission cool; if persistent, check hydraulic oil level.
Brake SystemREDA fault in the T6.195's service brake system, such as low pressure in wet disc brakes.Do not operate tractor; have brake system inspected immediately.
PParking BrakeAMBERThe parking brake on the T6.195 is engaged or not fully released.Release parking brake before moving; if light stays on, inspect brake switch.
Glow Plug / PreheatAMBERThe T6.195's intake air preheat system is active or a glow plug fault exists.Wait for preheat indicator to go out before starting; if flashing, service glow plugs.
DPF / RegenerationAMBERThe diesel particulate filter on the T6.195 requires automatic or manual regeneration.Operate at highway speed (if safe) to allow passive regen, or initiate parked regen from the display.
DEF / AdBlueAMBERThe T6.195's DEF level is low or system fault limits engine torque.Refill DEF with approved fluid; if light persists, check DEF quality and pump.
Water in FuelAMBERWater has been detected in the fuel filter/water separator of the T6.195.Drain water from separator and replace fuel filter if necessary.
Low FuelAMBERFuel level in the T6.195 tank is below 10% of 105-liter capacity.Refuel with clean diesel and add fuel conditioner in cold weather.
High BeamBLUEThe headlights on the T6.195 are switched to high beam.Dim when approaching other vehicles to avoid glare.
PTOPTO EngagedGREENThe rear PTO on the T6.195 is active and driving attached implements.Disengage PTO before servicing or leaving the operator's seat.
Differential LockAMBERThe T6.195's rear differential lock is engaged for increased traction.Disengage on paved surfaces to prevent driveline damage.
Hydraulic Oil TemperatureAMBERHydraulic oil temperature in the T6.195 exceeds normal range due to heavy load or low oil level.Reduce hydraulic demand and allow oil to cool; check oil level and filter.
Engine Oil TemperatureAMBEREngine oil in the T6.195 is above the ideal operating temperature, reducing lubrication efficiency.Reduce engine load and monitor temperature; if high persists, check cooling system.
Air Filter RestrictionAMBERThe engine air filter on the T6.195 is clogged, restricting airflow.Replace the air filter element to prevent power loss and engine damage.
Service / Hour MeterAMBERThe T6.195 has reached a scheduled maintenance interval based on engine hours.Perform required service (oil change, filters) as indicated in the operator's manual.
Work LightsGREENThe T6.195's additional work lights are activated for night operations.Switch off work lights when not needed to preserve battery and reduce glare.
Beacon / Rotating LightGREENThe T6.195's roof beacon is illuminated for visibility in field or road work.Activate beacon when operating on public roads or in low-visibility conditions.

Most Important Warning Lights

Engine Overheating

Common causes

  • low coolant level
  • radiator blockage by chaff
  • failed thermostat

What to do

Stop engine immediately on the T6.195. After cooling, check coolant level, clean radiator screens, and inspect thermostat. If overheating persists, contact dealer.

Transmission Overheating

Common causes

  • heavy draft loads in high range
  • low hydraulic oil level
  • clogged transmission oil cooler

What to do

Reduce engine load and shift to a lower gear on the T6.195. Check hydraulic oil level and clean the external oil cooler. Allow transmission to cool before continuing.

DEF Quality / Pump Failure

Common causes

  • water contamination in DEF
  • frozen DEF in cold weather
  • DEF pump malfunction

What to do

Refill with fresh, certified DEF. If pump fails, the T6.195 may enter derate; contact New Holland service to replace pump and flush the system.

Fuel System Air Leak

Common causes

  • loose fuel line connection
  • cracked fuel filter housing
  • air ingress from water separator

What to do

Check all fuel lines and fittings on the T6.195 for leaks. Replace filter housing if cracked. Prime the system using the hand primer pump.

Hydraulic System Failure

Common causes

  • pump cavitation from low oil level
  • blocked suction strainer
  • failed pressure line seal

What to do

Stop all hydraulic functions on the T6.195. Verify oil level and top up with NH Hydraulic Oil. Clean the suction screen. Inspect hoses for leaks; replace damaged seals.

Frequently Asked Questions

What does the amber DPF regeneration light mean on my T6.195?

It indicates the diesel particulate filter needs cleaning. On the T6.195, you can initiate a parked regeneration via the monitor screen. Ensure the tractor is stationary, engine warm, and clear of combustibles.

Why does my T6.195 show a red master warning light?

The master stop light illuminates for severe faults like low oil pressure or high coolant temperature. Immediately shut off the engine and refer to the message center for the specific code, then contact your dealer.

How often should I service my T6.195's hydraulic oil?

New Holland recommends changing the hydraulic oil every 600 hours or annually, whichever comes first, and replacing the filter every 300 hours. Check the level daily.

Can I operate my T6.195 with the DEF light on?

Only for a limited time. The T6.195 will gradually reduce engine torque if DEF level drops or a system fault occurs, eventually limiting speed. Refill DEF or fix the issue promptly.

What is the proper park regeneration procedure for the T6.195?

Park the tractor on level ground, engage parking brake, idle the engine, and press the regen button on the armrest display. The process takes about 30 minutes; do not interrupt.

Why does my T6.195 glow plug light stay on after starting?

If the preheat indicator stays on, it may indicate a faulty glow plug or relay. On the T6.195, this can cause hard starting. Have the glow plug system checked by a technician.
