2016 JEEP GRAND CHEROKEE check engine light

WARNING!
• Side Air Bags need room to inflate. Do not lean against the door or window. Situpright in the center of the seat.
• Being too close to the Side Air Bags during deployment could cause you to be
severely injured or killed.
• Relying on the Side Air Bags alone could lead to more severe injuries in a
collision. The Side Air Bags work with your seat belt to restrain you properly. In
some collisions, Side Air Bags won’t deploy at all. Always wear your seat belt
even though you have Side Air Bags.
• This vehicle is equipped with left and right Supplemental Side Air Bag
Inflatable Curtains (SABICs). Do not stack luggage or other cargo up high
enough to block the deployment of the SABICs. The trim covering above the
side windows where the SABIC and its deployment path are located should
remain free from any obstructions.
• This vehicle is equipped with SABICs. In order for the SABICs to work as
intended, do not install any accessory items in your vehicle which could alter
the roof. Do not add an aftermarket sunroof to your vehicle. Do not add roof
racks that require permanent attachments (bolts or screws) for installation on
the vehicle roof. Do not drill into the roof of the vehicle for any reason.
• Do not use accessory seat covers or place objects between you and the Side Air
Bags; the performance could be adversely affected and/or objects could be
pushed into you, causing serious injury.
Enhanced Accident Response System
In the event of an impact, if the communication network remains intact, and the
power remains intact, depending on the nature of the event, the ORC will determine
whether to have the Enhanced Accident Response System perform the following
functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or until the hazard light button
is pushed. The hazard lights can be deactivated by pushing the hazard light
button.
• Turn on the interior lights, which remain on as long as the battery has power.
• Unlock the power door locks.
Enhanced Accident Response System Reset Procedure
In order to reset the Enhanced Accident Response System functions after an event,
the ignition switch must be changed from ignition START or ON/RUN to ignition OFF.
Carefully check the vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before resetting the system and
starting the engine.

Air Bag Warning Light
The air bags must be ready to inflate for your protection in a collision. The Occupant
Restraint Controller (ORC) monitors the internal circuits and interconnecting wiring
associated with air bag system electrical components.
The ORC monitors the readiness of the electronic parts of the air bag system
whenever the ignition switch is in the START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC position, the air bag system is not on and
the air bags will not inflate.
The ORC turns on the Air Bag Warning Light in the instrument panel for approxi-
mately four to eight seconds for a self-check when the ignition switch is first turned
to the ON/RUN position. After the self-check, the Air Bag Warning Light will turn off.
If the ORC detects a malfunction in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A single chime will sound to alert
you if the light comes on again after initial startup.
If the Air Bag Warning Light in the instrument panel is not on during the four to eight
seconds when the ignition switch is first turned to the ON/RUN position, stays on, or
turns on while driving, have the vehicle serviced by an authorized service center
immediately.
NOTE:
If the speedometer, tachometer, or any engine related gauges are not working, the
Occupant Restraint Controller (ORC) may also be disabled. In this condition the air
bags may not be ready to inflate for your protection. Have an authorized dealer
service the air bag system immediately.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist in understanding how a
vehicle’s systems performed. The EDR is designed to record data related to vehicle
dynamics and safety systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal;and,
• How fast the vehicle was traveling.
GETTING STARTED
22

For the first 1500 miles (2414 km):
• Do not participate in track events, sport driving schools, or similar activities duringthe first 1500 miles (2414 km).
NOTE:
Check engine oil with every refueling and add if necessary. Oil and fuel consumption
may be higher through the first oil change interval.
HEADLIGHT SWITCH
The headlight switch is located on the left side of the instrument panel, next to the
steering wheel. The headlight switch controls the operation of the headlights, parking
lights, instrument panel lights, cargo lights and fog lights (if equipped).
To turn on the headlights, rotate the
headlight switch clockwise. When the
headlight switch is on, the parking lights,
taillights, license plate light and instru-
ment panel lights are also turned on. To
turn off the headlights, rotate the head-
light switch back to the O (Off) position.
NOTE:
• Your vehicle is equipped with plastic headlight and fog light (if equipped)
lenses that are lighter and less suscep-
tible to stone breakage than glass
lights. Plastic is not as scratch resis-
tant as glass and therefore different
lens cleaning procedures must be fol-
lowed.
• To minimize the possibility of scratch- ing the lenses and reducing light out-
put, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild
soap solution followed by rinsing.
CAUTION!
Do not use abrasive cleaning components, solvents, steel wool or other abrasive
materials to clean the lenses.

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 significantweight.
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

– Transmission Temperature Warning Light
This light indicates that there is excessive transmission fluid temperature that might
occur with severe usage such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle, with the transmission in NEUTRAL, until the light turns
off. Once the light turns off, you may continue to drive normally.
CAUTION!
Continuous driving with the Transmission Temperature Warning Light illuminated
will eventually cause severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the Transmission Temperature Warning
Light is illuminated you could cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
– Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition switch is turned to the ON/RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that service is required. However,
the conventional brake system will continue to operate normally if the BRAKE
warning light is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have the light inspected by an
authorized dealer.
– Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb check when the ignition
switch is first turned to the ON/RUN position. If the light is either not on during
starting, stays on, or turns on while driving, have the system inspected at an
authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things To
Know Before Starting Your Vehicle” in your Owner’s Manual on the DVD for further
information.
NOTE:
The Air Bag System is designed to be maintenance free.
WHAT TO DO IN EMERGENCIES
190

– Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition when the vehicle has completely stopped and the gear selector is placed in
the PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when
the engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require
towing.
– Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly, when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a Tire Pressure
Monitoring System (TPMS) which display in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID) when one or more of your tires is
significantly under-inflated. Accordingly, when the low tire pressure EVIC or DID
display illuminates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping
ability.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
After inflation, the vehicle may need to be driven for 20 minutes before the flashing light
will turn off.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the TPMS low EVIC or DID display.
