Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Radiator blockage
- Faulty fan clutch
What to do
Stop the engine on your HX235LCR immediately, allow it to cool, then check coolant level and clean the radiator fins. If persistent, inspect the fan clutch or water pump.
Hydraulic System Overheat
Common causes
- Low hydraulic oil level
- Clogged oil cooler
- Excessive load
What to do
Reduce load and allow the HX235LCR to idle. Check hydraulic oil level and clean the oil cooler core. If the light remains, contact service.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Worn engine bearings
What to do
Shut down your HX235LCR immediately. Check engine oil level and top up if low. If pressure does not return, do not restart; call a technician.
Battery Charging Failure
Common causes
- Loose alternator belt
- Faulty alternator
- Bad battery connection
What to do
Check alternator belt tension and battery cable connections on the HX235LCR. If the light stays on, the alternator may need replacement.
Fuel Filter Water Contamination
Common causes

Drain the water separator on your HX235LCR immediately. Replace the fuel filter if the light remains after draining.
Frequently Asked Questions
How do I reset the service hour meter light on my HX235LCR?
After performing the required maintenance, press and hold the trip reset button on the instrument cluster for 5 seconds until the light turns off.
Why does my HX235LCR show a hydraulic system warning when it's cold?
Cold hydraulic oil is thicker; it may trigger a high-pressure warning until the oil warms up. Let the machine idle to warm the oil before operation.
Can I operate the HX235LCR with the check engine light on?
It is not recommended. The light indicates an emissions issue that may affect performance. Have it diagnosed promptly to avoid further problems.
What does the swing lock light mean on the HX235LCR?
The swing lock is engaged to prevent the upper structure from rotating. Disengage it using the switch on the console before slewing.
How often should I replace the fuel filter on my HX235LCR?
Hyundai recommends every 500 hours or when the fuel filter warning appears, whichever comes first. Always use genuine Hyundai filters.
Why is my HX235LCR master caution light flashing?
A flashing master caution indicates a less critical fault, such as a clogged air filter or low hydraulic oil. Check the display for the specific code.
