Checking Coolant
The vehicle must be on a level surface. When your
engine is cold, check the dipstick on the cap of the
coolant recovery tank. The coolant level should be at
COLD, or a little higher. When your engine is warm, the
level on the dipstick should be up to HOT, or a
little higher.

If this light comes on and stays on, it means you’re low
on engine coolant.
Adding Coolant to the Recovery Tank
If you need more coolant, add the proper DEX
-COOL
coolant mixture at the coolant recovery tank, but only
when your engine is cool. If the tank is very low or
empty, also add coolant to the radiator. See “Engine
Overheating” in the Index for information.
