2014 JEEP GRAND CHEROKEE oil type

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and drivetrain (transmission and
axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the limits of local traffic laws
contributes to a good break-in. Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a high-quality energy
conserving type lubricant. Oil changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. For the recommended viscosity
and quality grades, refer to “Maintaining Your Vehicle.”
NOTE:
A new engine may consume some oil during its first few thousand miles (kilometers)
of operation. This should be considered a normal part of the break-in and not
interpreted as an indication of an engine problem or malfunction.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may
result.
SRT Engine Break-In Recommendations
SRT Engine Break-In Recommendations: The following tips will be helpful in
obtaining optimum performance and maximum durability for your new SRT Vehicle.
Despite modern technology and World Class manufacturing methods, the moving
parts of the vehicle must still wear in with each other. This wearing in occurs mainly
during the first 500 miles (805 km) and continues through the first oil change
interval.
It is recommended for the operator to observe the following driving behaviors during
the new vehicle break-in period:
0 to 100 miles (0 to 161 km):
• Do not allow the engine to operate at idle for an extended period of time.
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid
acceleration.
• Avoid aggressive braking.
• Drive with the engine speed less than 3,500 RPM.
• Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due to its construction. Normal
operation is allowed, providing the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant
weight.
NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
The engine oil installed in the engine at the factory is a high-quality energy conserving
type lubricant. Oil changes should be consistent with anticipated climate conditions
under which vehicle operations will occur. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
DIESEL ENGINE STARTING PROCEDURES
Normal Starting Procedure
1. Apply the parking brake.
2. Ensure the shift lever is in the PARK position.
3. Press and hold the brake pedal while pressing the ENGINE START/STOP button
once.
4. The system will take over and attempt to start the vehicle. If the vehicle fails to
start, the starter will disengage automatically after 30 seconds.
5. If you wish to stop the cranking of the engine prior to the engine starting, press the
button again.
6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.
NOTE:
A delay of the start-up can be as long as five seconds under very cold conditions. The
"Wait to Start" telltale will be illuminated during the pre-heat process and the start
will commence upon the telltale going out.

Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle is operated in a dusty and
off road environment. This type of vehicle use is considered Severe Duty.
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
Refer to the Maintenance Schedules on the following pages for required mainte-
nance.
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 irregular wear, even if it occurs before the oil
indicator system turns on.
•
Inspect battery and clean and tighten terminals as required.
•
Inspect automatic transmission fluid if equipped with dipstick.
•
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.
