| Fasten Seat Belt | RED | Seat belt not fastened on the XERION 4500; safety reminder. | Fasten seat belt immediately. | |
| Reduced Power (Limp Mode) | AMBER | Engine power limited due to fault on the XERION 4500; performance is reduced. | Complete work and contact dealer for diagnosis. | |
| Hydraulic Oil | RED | Low hydraulic oil level or high temperature on the XERION 4500. | Check hydraulic oil reservoir and coolers. | |
| Air Filter | AMBER | Intake air filter restriction on the XERION 4500; clean or replace filter. | Service air filter according to maintenance schedule. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter needs replacement or water separator full on the XERION 4500. | Replace fuel filter and drain water separator. | |
| Service / Hour Meter | AMBER | Scheduled maintenance interval approaching on the XERION 4500. | Perform next service as per the operator's manual. | |
| Work Lights | GREEN | Rear or front work lights are turned on the XERION 4500. | No action; use as needed for field work. | |
| Beacon / Rotating Light | GREEN | Roof beacon activated on the XERION 4500 for visibility. | No action; ensure beacon is on when on public roads. | |
| Differential Lock | GREEN | Front and/or rear differential lock engaged on the XERION 4500. | Disengage when not needed to avoid tire wear. | |
| PTO Engaged | GREEN | Power take-off is running on the XERION 4500. | Ensure PTO is disengaged when not in use. | |
| Air Brake Pressure (Low) | RED | Air brake system pressure below safe level on the XERION 4500. | Wait for compressor to build pressure; check for leaks. | |
| Engine / Exhaust Brake | GREEN | Engine brake or exhaust brake is active on the XERION 4500. | No action; use on slopes for speed control. | |
| Trailer | GREEN | Trailer connection detected on the XERION 4500. | Ensure trailer brakes are working before driving. |

Most Important Warning Lights
Engine Oil Pressure Low
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
Immediately shut off the XERION 4500 engine. Check oil level and top up if low; if level is OK, call Claas service to prevent bearing damage.
Coolant Overheating
Common causes
- Low coolant level
- Fan belt slippage
- Radiator blockage
What to do
Reduce engine load to idle, then park. Allow engine to cool before opening cap. Top up with recommended coolant and clean radiator fins on the XERION 4500.
Brake System Failure
Common causes
- Brake fluid leak
- Worn brake pads
- Air in brake lines
What to do
Do not operate the XERION 4500. Check brake fluid reservoir; if low, inspect for leaks. Bleed brakes if spongy, or replace pads as needed.
Transmission Overheating
Common causes
- High load in hot conditions
- Low CVT oil level
- Clogged oil cooler
What to do
Stop the XERION 4500 and let transmission idle in neutral. Check oil level and clean cooler fins. Avoid prolonged heavy pulling thereafter.
Air Brake Pressure Loss
Common causes
- Compressor fault
- Air line leak
- Moisture in system
What to do
Park the XERION 4500 and wait for pressure to recover. Inspect air lines for leaks; drain air tanks daily. If compressor fails, replace.
Frequently Asked Questions
What does the red master warning light mean on my XERION 4500?
It indicates a critical fault requiring immediate stop—check the central display for specific messages (e.g., engine, brakes). Park safely and contact Claas support.
Why is my XERION 4500 in limp mode and the reduced power light on?
Limp mode protects the engine from damage due to issues like high coolant temp or low oil pressure. Reduce load and complete the current task; have the tractor diagnosed afterward.
How do I initiate a DPF regeneration on the XERION 4500?
Drive above 30 km/h for 20 minutes if the light flashes. Alternatively, use the menu to start a parked regeneration only in a well-ventilated area away from flammables.
What should I do if the DEF/AdBlue light stays on after refilling?
The system may need resetting or the quality could be poor. Turn ignition on-off, and if light persists, check DEF pump and heater—visit a dealer.
Can I operate the XERION 4500 with the oil pressure light on?
No. Low oil pressure can destroy the engine. Stop immediately, check level, and if OK, do not restart without professional inspection.
How to check hydraulic oil level on the XERION 4500?
Park on level ground, retract all cylinders, and check the sight glass near the hydraulic tank. Top up with recommended oil if below the mark.
