2015 JEEP CHEROKEE cooling

WARNING!(Continued)
•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for
cuts, frays, and loose parts. Damaged parts must be
replaced immediately. Do not disassemble or modify the
system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding seat
belt or retractor condition, replace the seat belt.
Air Bag Warning Light
The light should come on and remain on for
four to eight seconds as a bulb check when the
ignition switch is first turned ON. If the light is

16. Fuel Gauge/Fuel Door Reminder
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON/RUN position. The fuel
pump symbol points to the side of the vehicle where the
fuel door is located.
17. 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 dealer 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
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your

Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
18. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an Onboard Diagnostic system called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to
ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
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.

provides a greater gear reduction ratio to provide in-
creased torque at the wheels.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
15. SERV 4WD Indicator Light — If Equipped
This light alerts the driver that the 4WD is in need of
service. If this light is illuminated, see your authorized
dealer as soon as possible.
16. 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.

Oil Change Reset
Oil Change Due
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Due” message will
display in the EVIC for five 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 is cycled to the ON/RUN
position. To turn off the message temporarily, push and
release the OK button. To reset the oil change indicator
system (after performing the scheduled maintenance)
refer to the following procedure.
1. Without pushing the brake pedal, push the ENGINE
START/STOP button and cycle the ignition to the
ON/RUN position (do not start the engine.)
2. Fully push the accelerator pedal, slowly, three times
within 10 seconds.
3. Without pushing the brake pedal, push the ENGINE
START/STOP button once to return the ignition to the
OFF/LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.

•Loose Fuel Filler Cap Message Indicator
This telltale will turn on to indicate the fuel
filler cap is loose.
13. Odometer Display/Fuel Gauge/Temperature Gauge/
Submenu Area
•The odometer display shows the total distance the
vehicle has been driven.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser
the correct mileage that the vehicle has been driven. If
your odometer needs to be repaired or serviced, the
repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he
cannot do so, then the odometer must be set at zero,
and a sticker must be placed in the door jamb stating
what the mileage was before the repair or service. It
is a good idea for you to make a record of the
odometer reading before the repair/service, so that
you can be sure that it is properly reset, or that the
door jamb sticker is accurate if the odometer must be
reset at zero.
When the appropriate conditions exist, this display
shows the Driver Information Display (DID) mes-
sages and Submenus.

Front Blower Control
There are seven blower speeds. Use
this control to regulate the amount of
air forced through the system in any
mode you select. The blower speed
increases as you move the control
clockwise from the OFF position.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the knob coun-
terclockwise, from top center into the
blue area of the scale, indicates cooler
temperatures. Rotating the knob clock-
wise, into the red area, indicates
warmer temperatures.
Air Conditioning Operation
Push the A/C button to engage the Air Conditioning
(A/C). A LED will illuminate when the A/C system is
engaged.
MAX A/C
For maximum cooling, when MAX A/C is selected the
A/C is turned on automatically and the air is
recirculated.
NOTE:A/C cannot be deselected when in MAX A/C
position. The LED will blink three times if the A/C
button is pushed. If your air conditioning performance
seems lower than expected, check the front of the A/C
condenser (located in front of the radiator), for an accu-
mulation of dirt or insects. Clean with a gentle water
spray from behind the radiator and through the con-
denser. Fabric front fascia protectors may reduce airflow
to the condenser, reducing air conditioning performance.
