2019 JEEP COMPASS engine coolant

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.

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.

windshield washer fluid is low.
— Engine Check/Malfunction
Indicator Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
This warning light will illuminate when the
ignition is in the ON/RUN position beforeengine start. If the bulb does not come on
when turning the ignition switch from OFF to
ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced by an authorized dealer as
soon as possible if this occurs.WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.

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

SCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the car under the best conditions.
For this reason, Jeep has planned a series of
checks and services at fixed distance inter-
vals and, where provided, at fixed time inter-
vals, as described in the Scheduled Servicing
plan. To keep the car’s efficiency in tip-top
condition, in the following Scheduled Service
plan pages a few additional checks are listed
that should be carried out more frequently
with respect to the normal coupon redemp-
tion schedule. Scheduled Servicing is offered
by all authorized dealerships according to
fixed time or mileage intervals. If, during
each operation, in addition to the ones sched-
uled, the need arises for further replace-
ments or repairs, these may be carried out
with the owner's explicit agreement only.
The technicians at your dealership know your
vehicle best, and have access to factory trained
information, genuine Mopar parts, and specially
designed electronic and mechanical tools that
can help prevent future costly repairs. If your car
is used frequently for towing, the interval be-
tween one scheduled servicing operation and
the next should be reduced. More frequentmaintenance may be needed for vehicles in
severe operating conditions, such as dusty areas
and very short trip driving.
NOTE:
Scheduled Servicing interventions are set out
by the Manufacturer. Failure to have them
carried out may invalidate the warranty. It is
advised to inform an authorized dealership of
any small operating irregularities without
waiting for the next 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.

•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
