service interval JEEP GRAND CHEROKEE 2016 WK2 / 4.G User Guide

Adding Diesel Exhaust Fluid
The DEF gauge (located in the DID) will display the level of DEF remaining in the
tank.
Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Driver Information Display (DID).
NOTE:
• The gauge may take up to five seconds to update after adding a gallon or more ofDiesel Exhaust Fluid (DEF) to the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See your authorized dealer for
service.
• The DEF gauge may also not immediately update after a refill if the temperature of the DEF fluid is below 12F (-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period of run time. Under very cold
conditions, it is possible that the gauge may not reflect the new fill level for several
drives.
NOTE:
• Driving conditions (altitude, vehicle speed, load, etc.) will effect the
amount of DEF that is used in your
vehicle.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with
an automatic DEF heating system.
This allows the DEF injection system to
operate properly at temperatures be-
low 12°F (-11°C).

Fuel Selection Use good quality diesel fuel from a repu-
table supplier in your vehicle. Federal law
requires that you must fuel this vehicle
with Ultra Low Sulfur Highway Diesel fuel
(15 ppm Sulfur maximum) and prohibits
the use of Low Sulfur Highway Diesel fuel
(500 ppm Sulfur maximum) to avoid dam-
age to the emissions control system. For
most year-round service, No. 2 diesel fuel
meeting ASTM specification D-975 Grade
S15 will provide good performance. We
recommend you use a blend of up to 5%
biodiesel, meeting ASTM specification
D-975 with your diesel engine.This vehicle
is compatible with biodiesel blends greater
than 5% but no greater than 20% biodiesel
meeting ASTM specification D-7467 pro-
vided the shortened maintenance intervals
are followed as directed.
Diesel Exhaust Fluid MOPAR Diesel Exhaust Fluid (API Certi-
fied) (DEF) or equivalent that has been API
Certified to the ISO 22241 standard. Use
of fluids not API Certified to ISO 22241
may result in system damage.
NOTE:
If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is required to
operate at colder-than-normal conditions for prolonged periods, use climatized No. 2
diesel fuel or dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide
better protection from fuel gelling or wax-plugging of the fuel filters.

Component Fluid, Lubricant, or Genuine Part
Automatic Transmission Use only Mopar ZF 8&9 Speed ATF Auto-
matic Transmission Fluid, or equivalent.
Failure to use the correct fluid may affect
the function or performance of your trans-
mission.
Transfer Case – Single-Speed (Quadra-Trac I)We recommend you use Shell Automatic
Transmission Fluid 3353.
Transfer Case – Two-Speed (Quadra-Trac II) We recommend you use MOPAR ATF+4 Automatic Transmission Fluid.
Axle Differential (Front) We recommend you use MOPAR GL-5 Syn-
thetic Axle Lubricant SAE 75W-85.

Axle Differential (Rear) – With Electronic
Limited-Slip Differential (ELSD) We recommend you use MOPAR GL-5 Syn-
thetic Axle Lubricant SAE 75W-85 with
friction modifier additive.
Axle Differential (Rear) – Without Elec-
tronic Limited-Slip Differential (ELSD) We recommend you use MOPAR GL-5 Syn-
thetic Axle Lubricant SAE 75W-85.

Brake Fluid, SAE J1703 should be used. If
DOT 3, SAE J1703 brake fluid is not avail-

MAINTENANCE PROCEDURES
For information on the maintenance procedures for your vehicle, please refer to
“Maintenance Procedures” in “Maintaining Your Vehicle” in your Owner’s Manual or
applicable supplement on the DVD for further details.
MAINTENANCE SCHEDULE — GASOLINE ENGINE
Your vehicle is equipped with an automatic oil change indicator system. The oil
change indicator system will remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures,
and E85 fuel usage will influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle
serviced as soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles
(16,000 km), twelve months or 350 hours of engine run time, whichever comes first.
The 350 hours of engine run or idle time is generally only a concern for fleet
customers.

WARNING!
• You can be badly injured working on or around a motor vehicle. Do only service work for which you have the knowledge and the
right equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.
• Failure to properly inspect and maintain your vehicle could result in a component malfunction and effect vehicle handling and
performance. This could cause an accident.

SRT 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 maintenance 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.
The Driver Information Display (DID) will display an “Oil Change Required” message
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 service is 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 oilchange. 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, whichever 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
than your authorized dealer, the message can be reset by referring to the steps
described under “Instrument Cluster Warning Lights” in “What To Do In Emergen-
cies” in this guide or “Driver Information Display (DID)” in “Understanding Your
Instrument Panel” in your Owners Manual on the DVD for further information.
At Each Stop For Fuel
• Check the engine oil level. Refer to “Maintenance Procedures/Engine Oil” in “Maintaining Your Vehicle” for further information.
• Check the windshield washer solvent and add if required.

Engine Oil Filter Replacement
Residual oil in the housing may spill from the housing when the new filter is installed
if the residual oil is not either removed from the housing or enough time has not
elapsed to allow the oil to drain back into the engine. When servicing the oil filter on
this engine, carefully remove the filter and use a suction gun to remove any residual
oil left in the housing or wait about 30 minutes for the oil to drain back into the
engine.
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, and fill asneeded
• Check function of all interior and exterior lights
