Mistu eclipes check engine light came on - it looks like this (!) what does that mean?

This is a low tire pressure indicator.

If the light is illuminated, it means one or more of your tires have fallen below 28 psi.
Take the vehicle to a shop or gas station and have the tires aired back up to 32psi (or your preference for pressure)
The light will go out after about 1/4 mile of driving at the right pressures.

If the light is flashing, you have a fault in the tire pressure monitor system and require service from a Mitsubishi dealer (factory scan tool is required for service)
