2016 JEEP GRAND CHEROKEE check engine light

– Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called
OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several of your typical
driving cycles. In most situations, the vehicle will drive normally and will not require
towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause
damage to the engine control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic converter damage and power
loss will soon occur. Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher
temperatures than in normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious injury to the driver, occupants
or others.
– Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
The “ESC Activation/Malfunction Indicator Light” in the instrument cluster will
come on when the ignition switch is turned to the ON/RUN position. It should go out
with the engine running. If the “ESC Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see your
authorized dealer as soon as possible to have the problem diagnosed and corrected.
NOTE:
• The “ESC Off Indicator Light” and the “ESC Activation/Malfunction IndicatorLight” come on momentarily each time the ignition switch is turned to ON/RUN.
• Each time the ignition is turned to ON/RUN, the ESC system will be ON, even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when ESC becomes inactive following the maneuver
that caused the ESC activation.
WHAT TO DO IN EMERGENCIES
194

Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle is operated in a dusty
and off road environment or is operated predominately at idle or only very low engine
RPM’s. 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 and fill asneeded.
• 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 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.

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.
MAINTAINING YOUR VEHICLE
237

Once A Month
• Check tire pressure and look for unusual wear or damage.
• Inspect the battery, and clean and tighten the terminals as required.
• Check the fluid levels of the coolant reservoir, engine oil, brake master cylinder,and add as needed.
• Check all lights and other electrical items for correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items may result in damage to the
vehicle.
MAINTAINING YOUR VEHICLE
238

MAINTENANCE SCHEDULE — DIESEL 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
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. 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.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles
(16,000 km) or twelve months, whichever comes first.
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
