| Glow Plug / Preheat | AMBER | Glow plugs are active or have a fault in the MC115C's cold-start system. | Wait for glow plug light to turn off before starting; if flashing, have system checked. | |
| DPF / Regeneration | AMBER | The diesel particulate filter in the Volvo MC115C requires regeneration to clear soot buildup. | Perform a parked regeneration or operate at high load until complete. | |
| DEF / AdBlue | AMBER | Diesel exhaust fluid level is low or system fault in the MC115C, affecting emissions compliance. | Refill DEF tank or service the DEF system. | |
| Water in Fuel | AMBER | Water has been detected in the fuel system of the Volvo MC115C, which can cause injection damage. | Drain the water separator immediately. | |
| Low Fuel | AMBER | Fuel level in the MC115C is low and needs refilling to avoid air in the system. | Refuel the machine soon. | |
| High Beam | BLUE | The high beam headlights are activated on the Volvo MC115C. | Switch to low beam when approaching other vehicles. | |
| Hydraulic System | RED | A critical fault in the hydraulic system of the MC115C, such as low pressure or overheating. | Stop the machine and inspect hydraulic fluid level and hoses. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature or level is outside normal range in the Volvo MC115C. | Check hydraulic oil level and allow system to cool if hot. | |
| Air Filter | AMBER | The engine air filter in the MC115C is restricted and needs cleaning or replacement. | Inspect and service the air filter element. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter or water separator requires service on the Volvo MC115C. | Replace fuel filter and drain water separator. | |
| Service / Hour Meter | AMBER | Indicates that scheduled maintenance is due based on engine hours on the MC115C. | Perform required service as per the maintenance schedule. | |
| Work Lights | GREEN | Work lights are turned on for enhanced visibility around the Volvo MC115C. | No action needed; it's a status indicator. | |
| Beacon / Rotating Light | GREEN | The rotating beacon is on, indicating the MC115C is operational and should be visible to others. | Ensure beacon is used as per site safety rules. | |
| Differential Lock | AMBER | The differential lock on the Volvo MC115C is engaged for increased traction. | Disengage when not needed to avoid drivetrain wear. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant
- Clogged radiator
- Faulty fan
What to do
Stop the MC115C immediately, allow engine to cool, check coolant level and radiator condition. If persistent, have cooling system serviced by Volvo dealer.
Low Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Worn bearings
What to do
Shut off engine; check oil level and top up if needed. If light remains, do not restart; call a technician to inspect oil system.
Hydraulic Overheat
Common causes
- Excessive load
- Low hydraulic oil
- Clogged cooler
What to do
Reduce load and idle engine to cool hydraulics. Check hydraulic oil level and clean cooler fins. If frequent, have system inspected.
DPF Full
Common causes
- Frequent low-load operation
- Delayed regeneration
- Sensor fault
What to do
Perform a parked regeneration following the MC115C operator manual. If regeneration fails, visit a Volvo dealer for service.
Transmission Overheat
Common causes
- Heavy continuous use
- Low transmission fluid
- Cooler blockage
What to do
Stop the machine and let transmission idle to cool. Check fluid level and inspect cooler for debris. Avoid prolonged high-load operation.
Frequently Asked Questions
What should I do if the master warning light comes on while operating the Volvo MC115C?
Immediately stop the engine and identify the secondary warning light that accompanied it. Refer to the operator's manual for the specific fault.
How do I perform a DPF regeneration on the MC115C?
Park the machine on level ground, engage the parking brake, and follow the regeneration prompt on the display. If the light does not clear, contact a Volvo dealer.
Why does my Volvo MC115C show a hydraulic caution light after heavy use?
This often indicates high hydraulic oil temperature due to sustained heavy loads. Allow the machine to idle to cool the system, and check oil level.
Can I operate the MC115C with the check engine light on?
It is not recommended. The light may indicate an emissions or sensor issue that could lead to reduced performance or further damage. Have it diagnosed soon.
What does the battery light mean on the Volvo MC115C?
It indicates a charging system fault, such as a failed alternator or loose belt. The machine may eventually lose electrical power; inspect charging components.
How often should I service the MC115C when the hour meter light appears?
The light signals that scheduled maintenance is due per the hour interval. Refer to the maintenance schedule in your operator manual; typical intervals are every 500 hours.
