What is the red flashing 4wd symbol below the green 4wd symbol on the dash?

The red flashing 4WD symbol typically indicates that there is a problem with the four-wheel-drive system, such as an issue with engagement or a malfunction in the system. It serves as a warning for the driver to check the vehicle's manual for troubleshooting steps or to seek professional assistance. If the red light remains on, it’s advisable to avoid using 4WD until the issue is resolved to prevent further damage.
