That symbol is your check engine light, which means the cars computer has found a fault somewhere in the system. These mostly deal with emissions control malfunctions.
Depending on the fault, the I drive may not alert you to the exact issue. If the light isnt flashing, the vehicle is safe to drive, but needs service to repair.
One common cause of light: Did you recently fill up the gas tank? If the cap is left loose this light can trigger. Try tightening the cap and see if the light resets after a couple drives.
