overheating JEEP GRAND CHEROKEE 2011 WK2 / 4.G User Guide

TOW/HAUL MODE
• When driving in hilly areas, towing atrailer, carrying a heavy load, etc.,
and frequent transmission shifting
occurs, press the TOW/HAUL switch
to select TOW/HAUL mode. This will
improve performance and reduce the
potential for transmission overheating
or failure due to excessive shifting.
When operating in TOW/HAUL
mode, transmission upshifts are
delayed, and the transmission will
automatically downshift (for engine
braking) during steady braking
maneuvers.
• The “TOW/HAUL Indicator Light” will illuminate in the instrument cluster to
indicate that TOW/HAUL mode has
been activated. Pressing the switch a
second time restores normal
operation. If the TOW/HAUL mode is
desired, the switch must be pressed
each time the engine is started.

IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating bytaking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into 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 Fan 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.
• If the temperature reading does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, 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.
