2018 JEEP COMPASS cooling

WARNING!
• When working near the radiator cooling
fan, disconnect the fan motor lead or
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.
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 brakefluid 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

CAUTION!
Proper operation of four-wheel drive ve-
hicles depends on tires of equal size, type
and circumference on each wheel. Any
difference in tire size can cause damage to
the power transfer unit. Tire rotation
schedule should be followed to balance
tire wear.
STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
• Park your vehicle in a covered, dry and
possibly airy location the windows open
slightly.
• Check that the Electric Park Brake is not
engaged.
• Disconnect the negative (-) terminal from
the battery post and be sure that the battery
is fully charged. During storage check bat-
tery charge quarterly.• If you do not disconnect the battery from
the electrical system, check the battery
charge every 30 days.
• Clean and protect the painted parts by
applying protective waxes.
• Clean and protect polished metal parts by
applying protective waxes.
• Apply talcum powder to the front and rear
wiper blades and leave raised from the
glass.
• Cover the vehicle with an appropriate cover
taking care not to damage the painted sur-
face by dragging across dirty surfaces. Do
not use plastic sheeting which will not
allow the evaporation of moisture present
on the surface of the vehicle.
• Inflate the tires at a pressure of +7.25 psi
(+0.5 bar) higher than recommended on
the tire placard and check it periodically.
• Do not drain the engine cooling system.
• Whenever you leave the vehicle is station-
ary for two weeks or more, run idle the
engine for approximately five minutes, withthe air conditioning system on and high fan
speed. This will ensure a proper lubrication
of the system, thus minimizing the possi-
bility of damage to the compressor when
the vehicle is put back into operation.
NOTE:
When the vehicle has not been started or
driven for at least 30 days, an Extended Park
Start Procedure is required to start the ve-
hicle. Refer to “Starting The Engine” in
“Starting And Operating” for further
information.
CAUTION!
Before removal of the positive and nega-
tive terminals to the battery, wait at least a
minute with ignition switch in the OFF
position and close the driver’s door. When
reconnecting the positive and negative ter-
minals to the battery be sure the ignition
switch is in the OFF position and the
driver’s door is closed.SERVICING AND MAINTENANCE
