Water temp light staying on??

We just bought my Daughter a low mileage 2007 Hatchback Accent and I noticed the water temp light on the dash stays on for about 4 to 5 minutes after you crank the car up. Is this normal for this model? It is not low of water.

4 to 5 minutes sounds too long for that light to be on. Does the light stay on like every time the car is started?

I believe it does come on everytime it is cranked, but if you crank it and the light goes off after about 3 or 4 minutes and the turn the car off and restart it then it doesn't come back on. I'll time it next time to see how long it stays.

Is it the blue light? Some had a blue and red (blue for low temperature, red for overheating)

The blue light would stay lit until the engine was up to its normal operating temperature. Mine has a gauge, but 5 minutes sounds about right based on what I see with my temperature gauge and scangauge to get to normal operating temp.

I'm having a brain fart but I believe it was a blue light. I tried to notice the time the last time I turned it on and I think it is more like 3 minutes. On our Kia and 2 Toyotas it is less than 1 minuts till the lights go off.

Some year Accent have the blue "engine cold" light, others don't. My year does not have the blue light. All that light means is the engine has not warmed up to operating temp, and the pcm has not entered closed loop. It means "please don't floor me or rev me up past 4k rpms until I warm up". Your okay until the red light comes on, which means "the engine is already overheated, turn me off right now or else I will blow a head gasket". I wish Hyundai put a temp gage in this year Accent, as it's nice to tell if the engine is "starting to overheat" instead of finding out it "already has overheated".

Really? A light that stays on in the cluster until the engine warms up? I know the engineer that designed that! I save "engineers" like that from themselves everyday at my job!
