| Glow Plug / Preheat | AMBER | Shows the preheating system is active or faulty on your AXION 900; if stays on, glow plugs may need replacement. | Wait for light to go out before starting; if persistent, visit dealer. | |
| DPF / Regeneration | AMBER | Indicates the diesel particulate filter is regenerating or needs manual regeneration on your AXION 900. | Operate at high load if possible; if light stays on, perform parked regen via menu. | |
| DEF / AdBlue | AMBER | Warns that AdBlue level is low or system has a fault in your AXION 900's SCR system. | Refill AdBlue at next opportunity; if light flashes, check system. | |
| Water in Fuel | AMBER | Indicates water has been detected in the fuel filter/water separator on your AXION 900. | Drain water from fuel filter separator immediately. | |
| Low Fuel | AMBER | Illuminates when fuel level is low in your AXION 900's tank. | Refuel as soon as possible to avoid running out. | |
| High Beam | BLUE | Burns blue when the high beam headlights are activated on your AXION 900. | No action needed; indicates headlight status. | |
| Hydraulic System | RED | Signals a hydraulic system fault, such as low oil pressure or filter clog, specific to AXION 900's load-sensing hydraulics. | Check hydraulic oil level and filter; if persists, contact service. | |
| Hydraulic Oil | AMBER | Indicates low hydraulic oil level or high temperature in your AXION 900's hydraulic system. | Check hydraulic oil level and top up if needed; allow system to cool. | |
| Engine Oil Temperature | AMBER | Warns that engine oil temperature is higher than normal in your AXION 900, reducing lubrication. | Reduce engine load and allow to cool; check oil level. | |
| Air Filter | AMBER | Indicates the engine air filter is clogged or needs service on your AXION 900. | Clean or replace the air filter element. | |
| Fuel Filter / Water Separator | AMBER | Signals that the fuel filter requires service or water has been detected in the separator on your AXION 900. | Replace fuel filter or drain water separator. | |
| Service / Hour Meter | AMBER | Illuminates to remind you that scheduled maintenance is due based on engine hours on your AXION 900. | Perform required service as per Claas maintenance schedule. | |
| Work Lights | GREEN | Turns green when the work lights (e.g., front or rear) are active on your AXION 900. | No action; indicates work light status. | |
| Beacon / Rotating Light | GREEN | Shows the rotating beacon is turned on for visibility in your AXION 900. | No action; indicates beacon status. | |
| Differential Lock | AMBER | Indicates the differential lock is engaged on your AXION 900; avoid turning sharply. | Disengage diff lock after use to prevent driveline stress. | |
| PTO Engaged | GREEN | Lights when the power take-off (PTO) is activated on your AXION 900. | Ensure safe operation; disengage when not in use. | |
| Trailer | GREEN | Indicates trailer connection and turn signal feedback on your AXION 900. | Check trailer lights if blinking rapidly. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator clogged
- Failed cooling fan
What to do
Stop the tractor immediately and idle engine. Check coolant level and inspect radiator for debris. For the AXION 900, ensure the reversible fan is operating correctly; if not, engage manual reverse to clean.
Transmission Overheat / Fault
Common causes
- Low transmission fluid
- Filter clogged
- Cooler blocked
What to do
Reduce load and allow transmission to cool. Check fluid level and inspect cooler for debris. On the AXION 900, use the dynamic power management to lower workload.
Hydraulic System Failure
Common causes
- Low hydraulic oil
- Filter clogged
- Pump failure
What to do
Check hydraulic oil level and top up if needed. Inspect filters and replace if dirty. For the AXION 900's load-sensing system, ensure the priority valve adjusts correctly; contact Claas service if pressure drops.
DPF / Regeneration Required
Common causes
- Extended idling
- Light load operation
- Faulty sensor
What to do
Drive at high load (above 1500 RPM) for 20-30 minutes to initiate passive regeneration. If light persists, perform parked regeneration via the CEMOS display. If regen fails, visit dealer for filter cleaning or replacement.
AdBlue / DEF System Issue
Common causes
- Low AdBlue level
- Poor quality AdBlue
- Injector clogged
What to do
Refill with high-quality AdBlue. If light flashes, check for system faults via the info display. On the AXION 900, ensure the SCR system is not in derate mode; have the injector inspected if needed.
Frequently Asked Questions
Why is the Master Warning (Stop) light on and the tractor won't move?
This indicates a critical fault such as engine or transmission failure. For the AXION 900, try restarting after a few minutes; if persistent, call Claas roadside assistance.
What should I do if the DPF regeneration light stays on after driving?
On the AXION 900, perform a stationary regeneration via the CEMOS menu. Ensure the tractor is parked safely, the PTO is off, and follow prompts. If it still fails, the filter may need professional cleaning.
How often should I drain the water from the fuel filter on my AXION 900?
Check daily, especially in humid conditions or after fueling. The AXION 900 has a fuel filter/water separator; open the drain valve at the bottom until water stops flowing.
Why does the hydraulic oil light flash intermittently?
Possibly low oil level or an intermittent sensor fault. On the AXION 900, check the oil level when cold; if okay, the sensor may need recalibration by a dealer.
What does the blue high beam light indicate?
It simply shows the high beam headlights are on. On the AXION 900, use the stalk to toggle; ensure not to blind oncoming traffic.
Why is the amber glow plug light staying on after starting?
The glow plug system may have a fault. On the AXION 900, it could be a relay issue or worn plugs. Have them tested; starting in cold weather may become harder.
