2014 JEEP GRAND CHEROKEE service indicator

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Seat Belt Reminder LightWhen the ignition switch is first turned to the
ON/RUN position, this light will turn on for four
to eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the driver
or front passenger seat belt remains unbuckled, the Seat
Belt Indicator Light will flash or remain on continuously.
Refer to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further information. 3. 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.
4. High Beam Indicator
Indicates that headlights are on high beam.

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.
11. Electronic Park Brake Failure Indicator —
If Equipped This light indicates the Electronic Parking
Brake system requires service.

If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever 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 autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing.
•Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a single
chime will sound after reaching a set threshold. Further overheating will cause the temperature gauge to pass
H,
the indicator will continuously flash and a continuous
chime will occur until the engine is allowed to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information.
• Electric Power Steering Malfunction – If Equipped
This telltale is on when the Electric Power
Steering is not operating and needs service.

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced. Refer
to “Replacement Tires” in this section for further infor-
mation.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
• Tire pressure
• Distance driven
• Performance tires, tires with a speed rating of V or
higher, and summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. Refer to the paragraph on
448 STARTING AND OPERATING

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emissions
tests can be performed.
• If the MIL is flashing, while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
512 MAINTAINING YOUR VEHICLE

For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine. NOTE:
If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the MIL symbol come on as part
of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not readyand you should
not proceed to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition or start the
engine. This means that your vehicle’s OBD II system
is ready and you can proceed to the I/M station.

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 main-
tenance 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.
On Electronic Vehicle Information Center (EVIC) equipped
vehicles, “Oil Change Required” will be displayed in the
EVIC 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 serviceis 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 oil change. 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, which-
ever 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
