If there is a rise in the temperature gauge check your radiator for coolant levels. You can water until it overflows and continues observing the gauge. If the problems persist, then you are certain of coolant leakage. It is dangerous driving with low engine coolant as it will destroy engine components.
What’s the low coolant light on my L5P?
I had the low coolant light come on as well, 8,000 miles on my L5P. It was -15 degrees outside on startup and it looked a little low, so I added some, and overfilled about 1/4inch above fill arrows on tank. My OCD has kicked in, does that little bit extra gonna hurt or not being over the fill mark?
What to do if your Radiator is leaking coolant?
If not, the worn hoses should be replaced.

When to add new coolant to a radiator?
It catches any overflow from the radiator. Most of these tanks move the coolant back into the radiator, making it an ideal choice to add new fluid. The fluid will move into the radiator when needed, preventing any overflows. Sometimes the radiator has a low fluid level and the overflow tank is full.

Solution: Get your vehicle to a mechanic immediately. Have it towed if necessary.
What happens when a radiator cap goes bad?
The radiator cap keeps the coolant inside the system, and at the right pressure. A faulty cap can allow coolant to escape, which can turn on the warning light. Solution: You or a mechanic can replace the bad cap with a new one. If you attempt this yourself, be sure to wait until the engine has cooled down completely — you could get badly burned.
The most common cause of low engine coolant level is external coolant leaks, but it can also disappear from other places. Here is a more detailed list of the most common causes of a low engine coolant level: As we told before, the most common cause of low engine coolant level is external leaks.
Where are the coolant marks on an overflow tank?
On the body of the overflow tank, you will find two marks, Full and Low. These lines tell whether the coolant is low or high. If the coolant is below the low mark, you have to add more coolant to the reservoir. Before you add extra coolant to the overflow tank, it is imperative to make sure the engine isn’t hot.
If there is a rise in the temperature gauge check your radiator for coolant levels. You can water until it overflows and continues observing the gauge. If the problems persist, then you are certain of coolant leakage. It is dangerous driving with low engine coolant as it will destroy engine components.
When does the low coolant level warning light go out?

What causes low coolant level in radiator surge tank?
The low coolant level in the radiator surge tank may be due to the fill process at the assembly plant, which cannot purge all of the air from the cooling system and the surge tank. After the engine has been thermally cycled, air rises and causes the coolant to become lower than when initially filled. Coolant Levels
