Is ok to drive with od light on in my 2008 Kia rio?

Driving with the OD (Overdrive) light on in your 2008 Kia Rio typically indicates that the overdrive function is disengaged, which can lead to higher engine RPMs and reduced fuel efficiency. While it may not cause immediate damage, it's advisable to address the issue promptly to avoid potential long-term effects on the transmission. If unsure, consult your owner's manual or a mechanic for guidance.
