Power Steering (EPS)REDElectric power steering system failure detected on the 6G Series, increasing steering effort.Stop safely and contact dealer for repair.
Hydraulic SystemAMBERThe hydraulic system pressure or temperature is abnormal on the 6G Series.Check hydraulic oil level and reduce load; if light persists, service required.
Fasten Seat BeltREDThe operator's seat belt is not fastened while the tractor is in motion on the 6G Series.Fasten your seat belt immediately before continuing operation.
Reduced Power (Limp Mode)AMBEREngine power is reduced to protect components due to a detected fault on the 6G Series.Finish work at reduced speed and have the fault diagnosed soon.
Hydraulic OilREDHydraulic oil level is critically low or oil temperature too high on the 6G Series.Stop the engine and check hydraulic reservoir; top up if needed.
Air FilterAMBERThe engine air filter is restricted and needs servicing on the 6G Series.Replace or clean the air filter element according to maintenance schedule.
Fuel Filter / Water SeparatorAMBERThe fuel filter requires replacement or water needs to be drained on the 6G Series.Drain any water and replace the fuel filter element at next service.
Service / Hour MeterAMBERA scheduled maintenance interval is approaching or due on your 6G Series.Refer to the operator's manual and perform required service.
Work LightsGREENThe auxiliary work lights are turned on for the 6G Series.Turn off when not needed to conserve battery.
Beacon / Rotating LightGREENThe warning beacon (rotating light) is active on your 6G Series.Ensure beacon is used when operating on public roads or in low visibility.
Differential LockGREENThe differential lock is engaged for maximum traction on the 6G Series.Disengage on hard surfaces to prevent driveline binding.
PTOPTO EngagedGREENThe power take-off (PTO) is engaged and rotating on the 6G Series.Disengage PTO when not in use for safety.
TrailerGREENA trailer or implement is electrically connected and detected by the 6G Series.Check trailer lights and brakes before road travel.
MINLow Oil LevelAMBEREngine oil level is low and needs topping up on the 6G Series.Check engine oil with dipstick and add oil as required.
Brake Fluid LevelREDBrake fluid level is critically low in the 6G Series brake system.Do not operate; check brake lines and refill fluid, then test brakes.
Door OpenAMBERThe cab door is not fully closed on the 6G Series.Close the door securely before moving.
High Exhaust Temp (HEST)AMBERThe exhaust system temperature is elevated during DPF regeneration on the 6G Series.Avoid parking near flammable materials until regeneration completes.

Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Faulty thermostat
  • Blocked radiator fins

What to do

Cool down the engine at low idle, check coolant level and top up; clean radiator exterior. If persists, have dealer inspect cooling system on your 6G Series.

Hydraulic System Failure

Common causes

  • Low hydraulic oil
  • Contaminated oil
  • Pump malfunction

What to do

Stop and check hydraulic oil level; add clean oil if low. If warning remains, avoid using hydraulics and contact Deutz-Fahr service for pump or filter inspection.

Transmission Overheating

Common causes

  • Excessive load
  • Low transmission fluid
  • Clogged cooler

What to do

Shift to a lower gear to reduce load; check transmission fluid level and condition. Allow transmission to cool before continuing heavy work.

Electrical System Issue

Common causes

  • Loose battery connections
  • Failed alternator
  • Blown fuse

What to do

Check battery terminals for tightness and corrosion; test alternator output. If battery light stays on, replace alternator or repair wiring on the 6G Series.

Brake System Malfunction

Common causes

  • Low brake fluid
  • Worn brake pads
  • Air in hydraulic lines

What to do

Stop the tractor immediately; check brake fluid reservoir; add fluid if low. If pedal feels spongy, bleed the brakes. For persistent faults, have dealer service the brakes.

Frequently Asked Questions

What does the red stop light mean on my 6G Series?

It indicates a critical fault requiring an immediate engine shutdown. Safely stop the tractor and refer to the display for the specific code, then contact your Deutz-Fahr dealer if needed.

Why is the DPF regeneration light flashing?

The diesel particulate filter needs active regeneration; driving at engine speeds above 1800 rpm for 20-30 minutes will clear the soot. Avoid short trips to prevent frequent regens.

How often should I drain the fuel water separator?

Drain it every 50 hours of operation or when the water-in-fuel warning appears. On the 6G Series, the separator is located near the fuel filter; turn the drain valve until clear fuel flows.

Can I continue working with the amber caution light on?

Yes, but you should address the indicated system soon to avoid more serious issues. Check the central display for details and schedule service at your earliest convenience.

What causes the transmission temperature warning?

Prolonged heavy load, low fluid level, or a clogged cooler. Reduce load and check fluid; if light persists, inspect the transmission cooler fins for debris.

How do I reset the service interval indicator?

After completing the required service, access the settings menu from the instrument cluster, navigate to 'Service Interval' and select 'Reset'. Follow on-screen prompts specific to your 6G Series.
