The Valtra S Series tractor's instrument cluster provides crucial real-time feedback tailored for high-horsepower farming operations. This guide helps you interpret the advanced warning system, ensuring optimal performance and safety during demanding field work.
Valtra S Series Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | Illuminates to signal a critical failure that demands immediate engine shutdown to prevent catastrophic damage to the Valtra S Series powertrain. | Stop the tractor safely and consult the engine fault codes via the SmartTouch display. | |
| Master Caution | AMBER | Lights up to warn of a non-critical system anomaly that requires attention before continuing prolonged operation. | Check the instrument cluster for other warning lights and review the message center on the armrest terminal. | |
| Check Engine (MIL) | AMBER | Indicates the emission control or engine management system has detected a fault, potentially affecting the S Series' AGCO Power engine performance. | Have the fault codes read by a Valtra dealer to diagnose the issue. | |
| Engine Oil Pressure | RED | Warns that engine oil pressure has dropped below safe levels, risking severe engine wear in the S Series' high-torque operation. | Immediately shut off the engine and check oil level; do not restart until resolved. | |
| Battery / Charging | RED | Alerts that the charging system voltage is too low, possibly due to a failing alternator or belt on the S Series. | Check alternator belt tension and battery connections; if persistent, seek service. | |
| Coolant Temperature | RED | Engine coolant has exceeded safe temperature, often caused by heavy PTO work or restricted airflow in the S Series cooling package. | Reduce load and allow engine to idle; check coolant level and radiator cleanliness. | |
| Transmission Temp | AMBER | Transmission oil temperature is elevated, which can degrade the CVT's performance in the Valtra S Series. | Reduce ground speed and shift to a lower gear; if light stays on, check transmission oil level. | |
| Brake System | RED | Indicates a general brake system fault, such as low pressure in the hydraulic brake circuit of the S Series. | Park the tractor and inspect brake fluid level and lines; do not operate until repaired. | |
| Parking Brake | RED | Glows when the parking brake is engaged, reminding the driver to release before moving the S Series. | Release the parking brake lever fully before driving. | |
| DPF / Regeneration | AMBER | The diesel particulate filter needs regeneration to clear accumulated soot; the S Series may automatically initiate regen when conditions allow. | Drive at higher engine speeds or park the tractor and start manual regeneration via the armrest display. | |
| DEF / AdBlue | AMBER | Warns that the AdBlue level is low or the system has a fault, affecting the S Series' SCR emissions compliance. | Refill AdBlue tank; if light persists, check system for contamination or sensor issues. | |
| Water in Fuel | AMBER | Detects water contamination in the fuel system, which can cause injection issues in the S Series common rail system. | Drain the water separator on the fuel filter; replace fuel filter if needed. | |
| Low Fuel | AMBER | Fuel level is low; the S Series has a large tank but operation should not be continued to avoid drawing air. | Refuel at nearest station; consider fuel additives for quality. | |
| High Beam | BLUE | Activated when the high beam headlights are on, providing extended visibility for the S Series during night field work. | Switch to low beam when approaching other vehicles. | |
| Hydraulic System | AMBER | Indicates a fault in the hydraulic system, such as low oil level or filter blockage, affecting implement control on the S Series. | Check hydraulic oil level and condition; service filter as per maintenance schedule. | |
| PTO Engaged | GREEN | Illuminates when the power take-off is engaged, reminding the operator that the driveline is active on the S Series. | Disengage PTO before leaving the cab or servicing implements. | |
| Differential Lock | GREEN | Lights up when the rear differential lock is engaged, improving traction in slippery conditions for the S Series. | Disengage differential lock when turning on hard surfaces to avoid driveline stress. | |
| Work Lights | GREEN | Indicates the rear or front work lights are activated for better visibility during night operations in the S Series. | Switch off work lights when not needed to save battery. |

Most Important Warning Lights
Engine Overheat
Common causes
- Clogged radiator fins
- Low coolant level
- Failed cooling fan
What to do
Clean the radiator externally, check coolant level, and inspect the fan drive belt or hydraulic fan motor on your S Series.
DPF Regeneration Failure
Common causes
- Frequent low-load operation
- Faulty soot sensor
- Incorrect fuel quality
What to do
Perform a stationary regeneration via the SmartTouch display; if repeated, consult a Valtra dealer for sensor diagnostics.
Transmission Malfunction
Common causes
- Low CVT oil level
- Contaminated oil
- Valve body issue
What to do
Check transmission oil level with the tractor on level ground; if light persists, have the CVT system analyzed by a Valtra service center.
AdBlue System Fault
Common causes
- AdBlue tank empty
- DEF pump failure
- NOx sensor malfunction
What to do
Refill AdBlue first; if warning remains, check for frozen fluid in cold weather or schedule a sensor replacement at a Valtra shop.
Brake System Failure
Common causes
- Hydraulic brake fluid leak
- Worn brake pads
- Air in brake lines
What to do
Inspect brake lines for leaks, top up fluid, and bleed the brakes; if pads are worn, replace them using Valtra approved parts.
Frequently Asked Questions
Why does my Valtra S Series show a red master warning with no other lights?
The master warning can activate for serious faults not shown by individual symbols, like a controller failure; check the message center on the armrest display for a specific code, then contact your dealer.
How do I perform a DPF regeneration on my S Series?
With the engine warm, park the tractor on level ground, ensure no flammable materials nearby, then go to 'DPF Regen' in the armrest menu and follow prompts; the process takes about 30 minutes.
What does the amber transmission temperature light mean when loading?
During heavy loading, the CVT oil can heat up; reduce engine speed and drive slower until the light extinguishes. If it stays on, check the oil level and cooler cleanliness.
Can I ignore the water in fuel light for a while?
No, water can damage the injection pump and injectors. Drain the water separator immediately; if the light stays on, replace the fuel filter.
My AdBlue light is on even though I filled the tank. What's wrong?
The system might need resetting or there could be an air lock. Drive the tractor for a few miles; if the light persists, the DEF quality sensor may be faulty.
Why does my S Series glow plug light flicker in cold weather?
Flickering indicates the preheat system is active to aid starting; wait for the light to go steady before cranking. If it stays on, the glow plug relay may need replacement.
