2016 JEEP GRAND CHEROKEE brake light

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
Normal Starting Procedure
1. Apply the parking brake.
2. Ensure the gear selector is in the PARK position.
3. Press and hold the brake pedal while pushing the ENGINE START/STOP button once and the system will engage the starter to crank the engine.
NOTE: • A delay of the start of up to five seconds is possible under very cold conditions.The “Wait to Start” telltale will be illuminated during the pre-heat process,
When the engine Wait To Start light goes off the engine will automatically crank.
• If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
4. Check that the oil pressure warning light has turned off.
5. Release the parking brake.

– 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.

– Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking
brake application. If the brake light turns on, it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is a problem with the brake
system master cylinder reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid
level is at the full mark on the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS)/Electronic Stability Control (ESC)
system. In this case, the light will remain on until the condition has been corrected.
If the problem is related to the brake booster, the ABS pump will run when applying
the brake, and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to
a portion of the hydraulic system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a specified level. The light will remain on
until the cause is corrected.
Vehicles equipped with the Anti-Lock Brake System (ABS) are also equipped with
Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the Brake
Warning Light will turn on along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by turning the ignition switch
from the OFF position to the ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off unless the parking brake
is applied or a brake fault is detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is applied with the ignition switch
in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It does not show the degree
of brake application.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have a collision.
Have the vehicle checked immediately.

Oil Change Required
Your vehicle is equipped with an engine oil change indicator system. The “Oil Change
Required” message will display in the DID for five seconds after a single chime has
sounded, to indicate the next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the engine oil change interval may
fluctuate, dependent upon your personal driving style.
Unless reset, this message will continue to display each time you turn the ignition
switch to the ON/RUN position or cycle the ignition to the ON/RUN position if
equipped with Keyless Enter-N-Go. To turn off the message temporarily, push and
release the OK button. To reset the oil change indicator system (after performing the
scheduled maintenance) refer to the following procedure.

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
