2019 JEEP COMPASS overheating

Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate,
or the AUTO button on the touchscreen (if
equipped) on the Automatic Temperature
Control (ATC) Panel.
2. Next, adjust the temperature you would
like the system to maintain by adjusting
the temperature control buttons. Once the
desired temperature is displayed, the sys-
tem achieves and automatically maintains
that comfort level.
3. When the system is set up for your comfort
level, it is not necessary to change the
settings. You experience the greatest effi-
ciency by simply allowing the system to
function automatically.
NOTE:
• It is not necessary to move the temperature
settings for cold or hot vehicles. The system
automatically adjusts the temperature,
mode, and blower speed to provide comfort
as quickly as possible.• The temperature can be displayed in U.S.
or Metric units by selecting the US/Metric
customer-programmable feature.
To provide you with maximum comfort in the
Automatic mode during cold start-ups, the
blower fan remains on low until the engine
warms up. The blower increases in speed and
transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
Operating Tips
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to pro-
vide proper corrosion protection and to pro-
tect against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and de-
froster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the Air Recircula-
tion mode during Winter months is not rec-
ommended, because it may cause window
fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for
about five minutes, in fresh air with the
blower setting on high. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.

2. Push the ENGINE START/STOP button a
second time to change the ignition switch
to the OFF mode.
Stopping The Engine
Vehicles Equipped With A Mechanical Key Fob:
To turn off the engine, proceed as follows:
1. Park the car in a position that does not
cause a traffic hazard.
2. Place the transmission in gear (models
with a manual transmission) or place the
transmission in PARK (P) (models with
automatic transmission).
3. With the engine idling, place the ignition
in the STOP/OFF position.
4. Remove the key from the ignition when
the engine is shut off.
Vehicles Equipped With Electronic Key
(Keyless Ignition):
To shut off the engine with vehicle speed
greater than 5 mph (8 km/h), you must push
and hold the START/STOP button or push theSTART/STOP button three times consecu-
tively within a few seconds. The engine will
shut down, and the ignition will be placed in
the RUN position.
Turning Off the car (placing the ignition from
the RUN position to the STOP position), the
power supply to the accessories are main-
tained for a period of three minutes.
Opening the driver side door with the ignition
in RUN will sound a short chime that reminds
the driver to place the ignition to STOP.
When the ignition is in the STOP/OFF posi-
tion, the window switches remains active for
three minutes. Opening a front door will can-
cel this function.
After severe driving, idle the engine to allow
the temperature inside the engine compart-
ment to cool before shutting off the engine.
Normal Starting — Diesel Engine
Before starting your vehicle, adjust your seat,
both inside and outside mirrors, and fasten
your seat belts.The starter is allowed to crank for up to
30-second intervals. Waiting a few minutes
between such intervals will protect the starter
from overheating.
WARNING!
• Before exiting a vehicle, always come to
a complete stop, then shift the auto-
matic transmission into PARK and apply
the parking brake.
• Always make sure the keyless ignition
node is in the OFF mode, key fob is
removed from the vehicle and vehicle is
locked.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Leaving children in a vehicle unattended
is dangerous for a number of reasons. A
child or others could be seriously or
fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
143

CAUTION!
Refer to “Recreational Towing” in “Start-
ing And Operating” and “Towing A Dis-
abled Vehicle” in “In Case Of Emergency”
for further information.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through all forward gears. The DRIVE
position provides optimum driving character-
istics under all normal operating conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain,
traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick
shift control to select a lower gear (refer to
"AutoStick" in this section for further infor-
mation). Under these conditions, using a
lower gear will improve performance and ex-
tend transmission life by reducing excessive
shifting and heat buildup.If the transmission temperature exceeds nor-
mal operating limits, the transmission con-
troller may modify the transmission shift
schedule, reduce engine torque, and/or ex-
pand the range of torque converter clutch
engagement. This is done to prevent trans-
mission damage due to overheating.
If the transmission becomes extremely hot,
the "Transmission Temperature Warning
Light" may illuminate, and the transmission
may operate differently until the transmis-
sion cools down.
During cold temperatures, transmission op-
eration may be modified depending on en-
gine and/or transmission temperature as well
as vehicle speed. This feature improves warm
up time of the engine and transmission to
achieve maximum efficiency. Engagement of
the torque converter clutch (and, for the
nine-speed, shifts into 8th or 9th gear), are
inhibited until the engine and/or transmis-
sion is warm (refer to the “Note” under
“Torque Converter Clutch” in this section).
Normal operation will resume once the tem-
perature(s) have risen to a suitable level.AUTOSTICK
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving
you more control of the vehicle. AutoStick
allows you to maximize engine braking, elimi-
nate undesirable upshifts and downshifts,
and improve overall vehicle performance.
This system can also provide you with more
control during passing, city driving, cold slip-
pery conditions, mountain driving, trailer
towing, and many other situations.
Operation
When the gear selector is in the AutoStick
position (beside the DRIVE position), it can
be moved forward and rearward. This allows
the driver to manually select the transmission
gear being used. Moving the gear selector
forward (-) triggers a downshift and rearward
(+) an upshift. The current gear is displayed
in the instrument cluster.
In AutoStick mode, the transmission will
shift up or down when the driver moves the
gear selector rearward (+) or forward (-), un-
less an engine lugging or overspeed condition
STARTING AND OPERATING

5. Start the engine in the vehicle that has the
booster battery, let the engine idle for a
few minutes, and then start the engine in
the vehicle with the discharged battery.
6. Once the engine is started, remove the
jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative(-)end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.
2. Disconnect the opposite end of the nega-
tive(-)jumper cable from the negative(-)
post of the booster battery.
3. Disconnect the positive(+)end of the
jumper cable from the positive(+)post of
the booster battery.
4. Disconnect the opposite end of the posi-
tive(+)jumper cable from the positive(+)
post of the vehicle with the discharged
battery.If frequent jump starting is required to start
your vehicle, you should have the battery and
charging system inspected at your authorized
dealer.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
REFUELING IN EMERGENCY
The fuel filling procedure in case of emer-
gency is described in the “Emergency Gas
Can Refueling”. Refer to “Refueling The Ve-
hicle” in “Starting And Operating” for further
information.
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating your en-
gine by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease engine idle speed.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads “H,” pull over and stop the
vehicle. Idle the vehicle with the air con-
ditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H” and you hear continu-
ous chimes, turn the engine off immedi-
ately and call for service.
223

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left
to clear the area around the front wheels. For
vehicles with automatic transmission, push
and hold the lock button on the gear selector.
Then shift back and forth between DRIVE and
REVERSE (for automatic transmission) or
SECOND GEAR and REVERSE (for manual
transmission) while gently pressing the ac-
celerator.
NOTE:
For vehicles with automatic transmission,
shifts between DRIVE and REVERSE can only
be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.Use the least amount of accelerator pedal
pressure that will maintain the rocking mo-
tion without spinning the wheels or racing the
engine.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your ve-
hicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
NOTE:
Push the “ESC Off” switch (if necessary), to
place the Electronic Stability Control (ESC)
system in “Partial Off” mode, before rocking
the vehicle. Refer to “Electronic Brake Con-
trol System” in “Safety” in the Owner’s
Manual for further information. Once the ve-
hicle has been freed, push the "ESC Off"
switch again to restore “ESC On” mode.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE/SECOND gear and
REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
225

Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst opera-
tion and prevent possible catalyst damage.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly mal-
functioning engine operation, a scorching
odor may suggest severe and abnormal cata-
lyst overheating. If this occurs, stop the ve-
hicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufactur-
er's specifications, should be obtained imme-
diately.
To minimize the possibility of catalytic con-
verter damage:
• Do not interrupt the ignition when the
transmission is in gear and the vehicle is in
motion.
• Do not try to start the vehicle by pushing or
towing the vehicle.• Do not idle the engine with any ignition
components disconnected or removed,
such as when diagnostic testing, or for
prolonged periods during very rough idle or
malfunctioning operating conditions.Cooling System
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 open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine
coolant (antifreeze) is dirty or rusty in appear-
ance, the system should be drained, flushed
and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser
for any accumulation of bugs, leaves, etc. If
dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
Cooling System Pressure Cap
The cap must be fully tightened to prevent
loss of engine coolant (antifreeze), and to
ensure that engine coolant (antifreeze) will
return to the radiator from the coolant expan-
sion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if
there is any accumulation of foreign material
on the sealing surfaces.
247

age or transmission malfunction, visit an au-
thorized dealer immediately to have the
transmission fluid level checked. Operating
the vehicle with an improper fluid level can
cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An au-
thorized dealer has the proper tools to
adjust the fluid level accurately.
RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
WARNING!
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle con-
trol.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure.
Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
