2013 JEEP COMPASS check engine

The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
the coolant freeze point or replacing the engine coolant
(antifreeze). Advise your service attendant of this. As
long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator. If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•
Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
expansion bottle must also be protected against
freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at
50% OAT engine coolant (antifreeze) (minimum) and
distilled water for proper corrosion protection of your
engine which contains aluminum components.
452 MAINTAINING YOUR VEHICLE

•Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” 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 temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. Fluid level can be expected to fall as the
brake pads wear. The brake fluid level should be checked

only the manufacturer’s recommended transmission
fluid which has the special friction coefficient additives
necessary for proper steel belt traction on the drive and
driven pulleys. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. It is important to maintain the transmission fluid at
the correct level using the recommended fluid.
No chemical flushes should be used in any transmission;
only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid will cause belt slip and
result in a complete transmission failure! Refer to
“Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.
Special Additives
Automatic transmission fluid is an engineered product
and its performance may be impaired by supplemental
additives. Therefore, do not add any fluid additives to
the transmission. The only exception to this policy is the
use of special dyes for diagnosing fluid leaks. Avoid
using transmission sealers as they may adversely affect
seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating conditions.
456 MAINTAINING YOUR VEHICLE

NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission as
needed
• Check function of all interior and exterior lights
Required Maintenance Intervals.
Refer to the maintenance schedules on the following
page for the required maintenance intervals.At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•Change oil and filter
• Rotate the tires. Rotate at the first sign of irregu-
lar wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required
• Inspect brake pads, shoes, rotors, drums, hoses
and park brake
• Inspect engine cooling system protection and
hoses
• Inspect exhaust system
• Inspect engine air cleaner if using in dusty or
off-road conditions
