2019 JEEP COMPASS engine overheat

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

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 blower 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.
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.
GEAR SELECTOR OVERRIDE
If a malfunction occurs, and the gear selector
cannot be moved out of the PARK position,
you can use the following procedure to tem-
porarily move the gear selector:
1. Turn the engine OFF.
2. Apply the park brake.
3. Grasp the boot material rearward of the
gear selector and pull up to carefully
separate the gear selector bezel and boot
assembly from the center console.4. Press and maintain firm pressure on the
brake pedal.
5. Insert a small screwdriver or similar tool
down into the gear selector override ac-
cess hole (at the right rear corner of the
gear selector assembly), and push and
hold the override release lever down.
6. Move the gear selector to the NEUTRAL
position.
7.
The vehicle may then be started in NEUTRAL.
8. Reinstall the gear selector boot.Gear Selector Bezel

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).

Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield or rear window.
Avoid using the wiper blades to remove frost
or ice from the windshield or rear window.
Make sure that they are not frozen to the
glass before turning them on to avoid damag-
ing the blade. Keep the wiper blade out of
contact with petroleum products such as en-
gine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.
Exhaust System
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can
be detected inside the vehicle; or when the
underside or rear of the vehicle is damaged;
have an authorized technician inspect the
complete 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, have the exhaust system inspected
each time the vehicle is raised for lubrication
or oil change. Replace as required.
WARNING!
• Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventu-
ally poison you. To avoid breathing CO,
refer to “Safety Tips” in “Safety” for
further information.
•
A hot exhaust system can start a fire if
you park over materials that can burn.
Such materials might be grass or leaves
coming into contact with your exhaust
WARNING!
system. Do not park or operate your ve-
hicle in areas where your exhaust system
can contact anything that can burn.
CAUTION!
• The catalytic converter requires the use
of unleaded fuel only. Leaded gasoline
will destroy the effectiveness of the
catalyst as an emissions control device
and may seriously reduce engine perfor-
mance and cause serious damage to the
engine.
• Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of en-
gine malfunction, particularly involving
engine misfire or other apparent loss of
performance, have your vehicle serviced
promptly. Continued operation of your
vehicle with a severe malfunction could
cause the converter to overheat, result-
ing in possible damage to the converter
and vehicle.
SERVICING AND MAINTENANCE
246

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

WARNING!
• Do not open hot engine cooling system.
Never add engine coolant (antifreeze)
when the engine is overheated. Do not
loosen or remove the cap to cool an
overheated engine. Heat causes pres-
sure to build up in the cooling system. To
prevent scalding or injury, do not remove
the pressure cap while the system is hot
or under pressure.
• Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood ser-
vices or immediately if the “Brake Warning
Light” is illuminated.
Be sure to clean the top of the master cylin-
der area before removing the cap. If neces-
sary, add fluid to bring the fluid level up to
the requirements described on the brake
fluid reservoir. With disc brakes, fluid level
can be expected to fall as the brake pads
wear. Brake fluid level should be checked
when pads are replaced. However, low fluid
level may be caused by a leak and a checkup
may be needed.
Use only manufacturer's recommended brake
fluid. Refer to “Fluids And Lubricants” in
“Technical Specifications” for further information.
WARNING!
• Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its per-
formance. The proper type of brake fluid
for your vehicle is also identified on the
original factory installed hydraulic mas-
ter cylinder reservoir.
• To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
closed container. Keep the master cylin-
der reservoir cap secured at all times.
Brake fluid in a open container absorbs
moisture from the air resulting in a lower
boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake fail-
ure. This could result in a collision.
