2020 Jeep Grand Cherokee Owner’s Manual — IF YOUR ENGINE OVERHEATS

In any of the following situations, you can reduce the poten- tial for overheating by taking the appropriate action.

• On the highways — slow down.

• In city traffic — while stopped, place the transmission in NEUTRAL (N), but do not increase the engine idle speed while preventing vehicle motion with the brakes.

NOTE:

There are steps that you can take to slow down an impending overheat condition:

• If your Air Conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.

• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to high. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system.
