2012 JEEP GRAND CHEROKEE operating temp

•If the liftgate handle is pulled while the power liftgate
is opening, the liftgate motor will disengage to allow
manual operation.
•If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and the liftgate must be opened or closed manu-
ally.
•If your liftgate is power closing and you put the
vehicle in gear, the liftgate will continue to power
close. However, vehicle movement may result in a
detection of an obstruction.
WARNING!
•Driving with the liftgate open can allow poison-
ous exhaust gases into your vehicle. You and your
passengers could be injured by these fumes. Keep
the liftgate closed when you are operating the
vehicle.
•If you are required to drive with the liftgate open,
make sure that all windows are closed, and the
climate control blower switch is set at high speed.
Do not use the recirculation mode.
Gas props support the liftgate in the open position.
However, because the gas pressure drops with tempera-
ture, it may be necessary to assist the props when
opening the liftgate in cold weather.

will become temporarily unavailable and the EVIC will
display the message “ Blind spot system unavailable-
Astronomy zone”. The side mirrors LED’s will be lit up
and stay lit until the vehicle exits the zone.

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
4. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the
ON/RUN position. It should go out with the
engine running. If the “ESC Activation/Malfunction In-
dicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is turned to
ON/RUN.
•Each time the ignition is turned to ON/RUN, the ESC
system will be ON, even if it was turned off previously.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.

25. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“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 the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealership for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see “Main-
taining Your Vehicle”. Follow the warnings under the
Cooling System Pressure Cap paragraph.

•Electronic Speed Control SETThis light will turn on when the electronic
speed control is SET. For further information,
refer to “Electronic Speed Control” in “Under-
standing The Features Of Your Vehicle.”
•Adaptive Cruise Control (ACC) ONThis light will turn on when the ACC is ON.
For further information, refer to “Adaptive
Cruise Control (ACC)” in “Understanding The
Features Of Your Vehicle.”
•Adaptive Cruise Control (ACC) SETThis light will turn on when the ACC is SET.
For further information, refer to “Adaptive
Cruise Control (ACC)” in “Understanding The
Features Of Your Vehicle.”
•Power Steering System Over Temperature — If
EquippedIf the “POWER STEERING SYSTEM OVER
TEMP” message and a icon are displayed on
the EVIC screen, it indicates that extreme steer-
ing maneuvers may have occurred, which
caused an over temperature condition in the power
steering system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, then pull
over and let vehicle idle. After five minutes, the system
will cool and return to normal operation. Refer to “Power
Steering” in “Starting and Operating” for further infor-
mation.

required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing.
•Engine Temperature Warning LightThis light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information.
•Transmission Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
