When driving a Freightliner, it’s important to be aware of the various warning lights that may appear on the dashboard. These lights indicate potential issues with the vehicle, and ignoring them could lead to further problems down the line.
Main Content
1. Check Engine Light
The check engine light is perhaps the most well-known warning light, and it can indicate a range of issues such as faulty sensors, a loose gas cap, or a more serious problem with the engine itself.
2. Oil Pressure Warning Light
This light will illuminate if the oil pressure drops to a dangerous level, which could be caused by a leak, a faulty oil pump, or a clogged oil filter.
3. Battery Warning Light
If the battery warning light comes on, it may indicate a problem with the battery, alternator, or charging system, and it’s important to have it checked as soon as possible to avoid a potential breakdown.
