Ram 1500 Dashboard Symbols FAQ
What is the most serious Ram 1500 warning light?
There is no single universal most-serious warning. Low oil pressure, overheating, serious brake problems and conditions affecting steering or vehicle control can require immediate attention. Follow the exact instrument-cluster message.
What does a red warning light mean on a Ram 1500?
Red warnings generally indicate conditions that can require immediate attention. The exact action depends on the symbol; a Door Open warning is different from an Oil Pressure or Brake warning.
What does a yellow warning light mean on a Ram 1500?
Yellow or amber warnings generally indicate a fault, reduced function or condition requiring attention. Some systems may still allow normal driving while the warning is present.
Why is my Ram 1500 Check Engine Light on?
The MIL can illuminate for many different engine, transmission, fuel or emissions-related conditions. A diagnostic scan is normally needed to identify the actual cause.
Why is my Ram 1500 TPMS light on?
One or more tires may have low pressure or the system may have detected pressure loss. Check all tire pressures when cold and use the pressure listed on the vehicle label.
Why is my Ram 1500 Service 4WD light on?
The Service 4WD warning indicates a fault in the four-wheel-drive system. Have the system diagnosed rather than assuming 4WD will continue to operate normally.
What does the Ram 1500 TOW/HAUL light mean?
It means TOW/HAUL mode is selected. It is a normal system-status indicator rather than a fault warning.
What does the blue headlight symbol mean on a Ram 1500?
The blue symbol indicates that the high-beam headlights are on. Switch to low beams when approaching or following other vehicles.
Why is my Ram 1500 air suspension light on?
First determine whether the indicator is showing a normal ride-height change or an actual Air Suspension Fault. Ram 1500 models with air suspension can display several normal height indicators.
