2014 JEEP GRAND CHEROKEE maintenance schedule

With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (antifreeze) (conforming to MS-
12106).
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.NOTE:
Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead
to severe internal engine damage. If any coolant is
needed to be added to the system please contact your
local authorized dealer.
Selection Of Coolant
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
CAUTION!
• Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine
damage and may decrease corrosion protection.
Organic Additive Technology (OAT) engine cool-
ant is different and should not be mixed with

•If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at
a minimum of 50% OAT coolant (conforming to
MS-12106) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.
• 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 emissions.
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.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
brake system warning light is on. If necessary, add fluid
to bring level to the full mark on the side of the reservoir

MAINTENANCE SCHEDULE
The Scheduled Maintenance services listed in this
manual must be done at the times or mileages specified
to protect your vehicle warranty and ensure the best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving. Inspection and service should also be done
anytime a malfunction is suspected.
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Electronic Vehicle Information Center (EVIC) equipped
vehicles, “Oil Change Required” will be displayed in the
EVIC and a single chime will sound, indicating that an oil
change is necessary.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that serviceis required for your vehicle. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
NOTE:
•
The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle’s oil
if it has been six months since your last oil change,
even if the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
• Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or six months, which-
ever comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
