2012 JEEP GRAND CHEROKEE temperature

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 Vehicle Information Center (EVIC)
Displays
The EVIC display consists of three sections:
1. The top line where compass direction, odometer line
and outside temperature are displayed.
2. The main display area where the menus and pop up
messages are displayed.
3. The reconfigurable telltales section below the odom-
eter line.
The main display area will normally display the main
menu or the screens of a selected feature of the main
menu. The main display area also displays pop upmessages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the Messagesmain menu item. As long
as there is a stored message, an iwill be displayed in the
EVIC’s compass/outside temp line. Examples of this
message type are Right Front Turn Signal Lamp Out
and Low Tire Pressure.
•Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples

•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.

WARNING!
If the Transmission Temperature Warning Light is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.
Engine Oil Change Indicator System
Oil Change Due
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Due” message will
flash in the EVIC display for approximately 10 seconds
after a single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate, dependent
upon your personal driving style.Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position or cycle the ignition to the ON/RUN position if
equipped with Keyless Enter-N-Go. To turn off the
message temporarily, press and release the MENU but-
ton. To reset the oil change indicator system (after
performing the scheduled maintenance) refer to the fol-
lowing procedure.

ing” for more information.
NOTE:Under certain conditions, the display may be
superseded by another display of higher priority. But
when the ignition switch position is changed, the display
always re-appears.
Compass / Temperature Display
The compass readings indicate the direction the vehicle is
facing. The EVIC will display one of eight compass
readings and the outside temperature.
NOTE: The system will display the last known outside
temperature when starting the vehicle and may need to
be driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect the
displayed temperature; therefore, temperature readings
are not updated when the vehicle is not moving.
Automatic Compass Calibration
This compass is self-calibrating, which eliminates the
need to manually reset the compass. When the vehicle is
new, the compass may appear erratic and the EVIC will
display CAL until the compass is calibrated. You may
also calibrate the compass by completing one or more
360–degree turns (in an area free from large metal or
