2019 JEEP COMPASS coolant temperature

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.

— Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Con-
tact an authorized dealer as soon as possible.
This indicates a possible problem with the
electrical system or a related component.
— Door Open Warning Light
This indicator will illuminate when a door is
ajar/open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a
single chime.
— Electric Power Steering Fault
Warning Light
This warning light will turn on when there's a
fault with the EPS (Electric Power Steering)
system. Refer to “Power Steering” in “Start-
ing And Operating” in the Owner’s Manual for
further information.
WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.
— Electronic Throttle Control (ETC)
Warning Light
This warning light will illuminate to indicate
a problem with the Electronic Throttle Con-
trol (ETC) system. If a problem is detected
while the vehicle is running, the light will
either stay on or flash depending on the
nature of the problem. Cycle the ignition
when the vehicle is safely and completely
stopped and the transmission is placed in the
PARK position. The light should turn off. If
the light remains on with the vehicle running,
your vehicle will usually be drivable; however,
see an authorized dealer for service as soon
as possible.
NOTE:
This light may turn on if the accelerator and
brake pedals are pressed at the same time.If the light continues to flash when the ve-
hicle is running, immediate service is re-
quired and you may experience reduced per-
formance, an elevated/rough idle, or engine
stall and your vehicle may require towing.
The light will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN posi-
tion and remain on briefly as a bulb check. If
the light does not come on during starting,
have the system checked by an authorized
dealer.
— Engine Temperature Warning Light
This warning light will illuminate to warn of
an overheated engine condition. If the engine
coolant temperature is too high, this light will
illuminate and a single chime will sound.
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 vehicle. If the
temperature reading does not return to nor-
mal, turn the engine off immediately and call
for service.
Refer to “If Your Engine Overheats” in “In
Case Of Emergency” for further information.
GETTING TO KNOW YOUR INSTRUMENT PANEL
66

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

WARNING!
• You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a com-
petent mechanic.
• Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.
Heavy Duty Use Of Vehicle
**** Change the engine oil and engine oil
filter at every 4500 miles (7,500 km) or
12 months if using your vehicle under any of
the following severe duty conditions:
• Stop and go driving.
• Driving in dusty conditions.
• Short trips of less than 10 miles (16 km).
• Trailer towing.• Taxi, police, or delivery service (commercial
service).
• Off-road or desert operation.
Diesel Engines
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for engine oil
replacement.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Oil Change Required” message is
displayed. Severe Operating Conditions can
cause the change oil message to illuminate
as earlier than specified. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service inter-
vals that are required to keep your vehicle
operating properly and safely.
The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your deal-
ership know your vehicle best, and have ac-
cess to factory trained information, genuine
Mopar parts, and specially designed elec-
tronic and mechanical tools that can help
prevent future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.
NOTE:
•The actual interval for changing engine oil
and replacing the engine oil filter depends on
the vehicle usage conditions, and is signaled
by the warning light or message in the instru-
ment panel. In any case, it must never exceed
12,000 miles (20,000km) or 1 year.
•Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
235

•Areas that are not dusty: recommended maxi-
mum distance 75,000 mi (120,000 km). The
belt must be replaced every 6 years, regard-
less of distance travelled. Dusty areas and/or
heavy conditions (severe weather conditions,
very low or very high temperatures for ex-
tended periods, urban driving, long periods of
idling): the recommended maximum distance
is 37,500 mi (60,000 km). The belt must be
replaced every 4 years, regardless of dis-
tance travelled.
Once A Month Or Before A Long Trip
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Check the fluid levels of the coolant reser-
voir and brake master cylinder, fill as
needed.• Check function of all interior and exterior
lights.
• Control and recovery of additive level for
AdBlue Diesel emissions (UREA) (if
equipped).
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
• Inspect for the presence of water in the fuel
filter/water separator unit.
Demanding Vehicle Use
• Restore additive level for AdBlue Diesel
emissions (UREA) (if equipped), when the
lamp is illuminated or the message on the
instrument panel.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.
SERVICING AND MAINTENANCE
236

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.
