blower JEEP GRAND CHEROKEE 2012 WK2 / 4.G User Guide

IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential foroverheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase engine idle speed.
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.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the
temperature gauge reads 240°F (116 °C) or greater pull over and stop
the vehicle. Idle the vehicle with the air conditioner turned off until the
pointer drops back into the normal range 200–230°F (93–110°C). If
the pointer remains at 240°F (116°C) or greater and you hear a chime,
turn the engine off immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze)
or steam from your radiator. If you see or hear steam coming from
under the hood, do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure cap when the
radiator or coolant bottle is hot.
