2016 JEEP GRAND CHEROKEE Engine

•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.90032)
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.
668 MAINTAINING YOUR VEHICLE

WARNING!(Continued)
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Front/Rear Axle Fluid
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected.
If gear oil leakage is suspected inspect the fluid level. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than 1/8 in
(3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.

CAUTION!
When installing plugs, do not overtighten. You could
damage them and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in this
section for fluid specifications. It is important to maintain
the transmission fluid at the correct level using the
recommended fluid.NOTE:
No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Refer to “Fluids, Lubricants, And Genuine
Parts” in this section for fluid specifications.
Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. Avoid using transmission seal-
ers as they may adversely affect seals.

WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do
not disassemble or modify the system. Seat belt
assemblies must be replaced after a collision if they
have been damaged (i.e., bent retractor, torn web-
bing, etc.).
FUSES
WARNING!
•When replacing a blown fuse, always use an ap-
propriate replacement fuse with the same amp
rating as the original fuse. Never replace a fuse
(Continued)
WARNING! (Continued)
with another fuse of higher amp rating. Never
replace a blown fuse with metal wires or any other
material. Failure to use proper fuses may result in
serious personal injury, fire and/or property dam-
age.
• Before replacing a fuse, make sure that the ignition
is off and that all the other services are switched off
and/or disengaged.
• If the replaced fuse blows again, contact an autho-
rized dealer.
• If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, gearbox system) or steering system
blows, contact an authorized dealer.
