check engine light JEEP GRAND CHEROKEE 2013 Owner handbook (in English)

To Release The Steering Wheel LockCycle the ignition and start the engine.
NOTE:
If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to
the right to disengage it. If you turned the
wheel to the left to engage the lock, turn the
wheel slightly to the left to disengage it.
SENTRY KEY®
The Sentry Key® Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed
or activated. Operation is automatic, regardless
of whether the vehicle is locked or unlocked.
The system uses the factory-mated Key Fob
with Remote Keyless Entry (RKE) transmitter
and Wireless Ignition Node (WIN) to prevent
unauthorized vehicle operation. Therefore, only
Key Fobs that are programmed to the vehicle
can be used to start and operate the vehicle.
The system will shut the engine off in two sec-
onds if an invalid Key Fob is used to start the
engine.After turning the ignition switch to the ON/RUN
position, the Vehicle Security Light will turn on
for three seconds for a bulb check. If the light
remains on after the bulb check, it indicates that
there is a problem with the electronics. In addi-
tion, if the light begins to flash after the bulb
check, it indicates that someone used an invalid
Key Fob to start the engine. Either of these
conditions will result in the engine being shut off
after two seconds.
If the Vehicle Security Light turns on during
normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there
is a fault in the electronics. Should this occur,
have the vehicle serviced as soon as possible
by an authorized dealer.
CAUTION!
•
Do not make modifications or alterations to
the immobilizer system. Modifications or
alterations to the immobilization system
may result in a loss of security protection.
(Continued)
CAUTION!(Continued)
•The Sentry Key® Immobilizer system is
not compatible with some after-market re-
mote starting systems. Use of these sys-
tems may result in vehicle starting prob-
lems and loss of security protection.
All of the Key Fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
Replacement Keys
NOTE:
Only Key Fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a Key Fob is
programmed to a vehicle, it cannot be pro-
grammed to any other vehicle.

Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To avoid
breathing (CO), follow these safety tips:
•Do not run the engine in a closed garage
or in confined areas any longer than
needed to move your vehicle in or out of
the area.
•
If you are required to drive with the trunk/
liftgate open, make sure that all windows are
closed and the climate control BLOWER
switch is set at high speed. DO NOT use the
recirculation mode.
• If it is necessary to sit in a parked vehicle
with the engine running, adjust your heat-
ing or cooling controls to force outside air
into the vehicle. Set the blower at high
speed. The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas
for broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.
Safety Checks You Should Make
Inside The Vehicle
Seat Belts
Inspect the belt system periodically, checking
for cuts, frays, and loose parts. Damaged parts
must be replaced immediately. Do not disas-
semble or modify the system. Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding belt or
retractor condition, replace the belt.
Air Bag Warning Light
The light should come on and re-
main on for four to eight seconds
as a bulb check when the ignition
switch is first turned ON. If the light
is not lit during starting, see your
authorized dealer. If the light stays
on, flickers, or comes on while driving, have the
system checked by an authorized dealer.
Defroster
Check operation by selecting the defrost mode
and place the blower control on high speed. You
should be able to feel the air directed against
the windshield. See your authorized dealer for
service if your defroster is inoperable.

Floor Mat Safety Information
Always use floor mats designed to fit the foot-
well of your vehicle. Use only floor mats that
leave the pedal area unobstructed and that are
firmly secured so that they cannot slip out of
position and interfere with the pedals or impair
safe operation of your vehicle in other ways.
WARNING!
Pedals that cannot move freely can cause
loss of vehicle control and increase the risk
of serious personal injury.
•
Always make sure that floor mats are prop-
erly attached to the floor mat fasteners.
•Never place or install floor mats or other
floor coverings in the vehicle that cannot
be properly secured to prevent them from
moving and interfering with the pedals or
the ability to control the vehicle.
(Continued)
WARNING!(Continued)
•Never put floor mats or other floor cover-
ings on top of already installed floor mats.
Additional floor mats and other coverings
will reduce the size of the pedal area and
interfere with the pedals.
• Check mounting of mats on a regular
basis. Always properly reinstall and secure
floor mats that have been removed for
cleaning.
• Always make sure that objects cannot fall
into the driver footwell while the vehicle is
moving. Objects can become trapped un-
der the brake pedal and accelerator pedal
causing a loss of vehicle control.
• If required, mounting posts must be prop-
erly installed, if not equipped from the
factory.
Failure to properly follow floor mat installa-
tion or mounting can cause interference with
the brake pedal and accelerator pedal opera-
tion causing loss of control of the vehicle.
Periodic Safety Checks You Should
Make Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight park-
ing for fuel, engine coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, power steering fluid, or brake fluid leaks
are suspected, the cause should be located and
corrected immediately.

INSTRUMENT CLUSTER
DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per
minute (RPM x 1000).
2. Air Bag Warning LightThis 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 Re-
straints” in “Things To Know Before Starting
Your Vehicle” for further information. 3. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL)
is part of an onboard diagnostic sys-
tem called OBD II that monitors en-
gine and automatic transmission con-
trol 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 condi-
tion checked promptly.
Certain conditions, such as a loose or missing
gas cap, 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 Indi-
cator Light (MIL) on could cause damage to
the engine control system. It also could affect
fuel economy and drivability. 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 ref-
erenced above, can reach higher tempera-
tures 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 re-
sult in death or serious injury to the driver,
occupants or others.

4.Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If Equipped
The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the igni-
tion 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 continu-
ously 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 Indicator Light”
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 click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive following the maneuver that caused
the ESC activation.
5.
TOW/HAUL Indicator Light — If Equipped
This light will illuminate when the
TOW/HAUL button has been se-
lected. The TOW/HAUL button is lo-
cated in the center of the instrument
panel (below the climate controls).
6. Turn Signal IndicatorThe arrows will flash with the exterior
turn signals when the turn signal lever
is operated. A tone will chime, and an
EVIC message will appear if the turn signals are
left on for more than 1 mile (1.6 km).
NOTE:
Check for an inoperative outside light bulb if
either indicator flashes at a rapid rate. 7. High Beam Indicator
Indicates that headlights are on high
beam.
8. Front Fog Light Indicator — If Equipped This indicator will illuminate when the
front fog lights are on.
9. Hill Descent Control Indicator Light — If
Equipped The symbol indicates the status of
the Hill Decent Control (HDC) fea-
ture. The lamp will be on solid
when HDC is armed. HDC can only
be armed when the transfer case is
in the “4WD Low” position and the vehicle
speed is less then 30 mph (48 km/h). If these
conditions are not met while attempting to use
the HDC feature, the HDC indicator lamp will
flash on/off.

Tighten the fuel filler cap properly and press the
SELECT button to turn off the message. If the
problem continues, the message will appear the
next time the vehicle is started.
•A loose, improperly installed, or damaged
fuel filler cap may also turn on the Malfunc-
tion Indicator Light (MIL).
• Windshield Washer Fluid Low Indicator
This light will turn on to indicate the
windshield washer fluid is low.
• SERV 4WD
The SERV 4WD light monitors the
electric shift 4WD system. If the
SERV 4WD light stays on or comes
on during driving, it means that the
4WD system is not functioning
properly and that service is required.EVIC Red Telltale LightsThis area will show reconfigurable red telltales.
These telltales include:
• Door Ajar
This light will turn on to indicate
that one or more doors may be
ajar.
• Liftgate Ajar
This light will turn on to indicate
that liftgate may be ajar.
• Liftgate Flipper Glass Ajar
This light will turn on to indicate
that liftgate flipper glass may be
ajar. •
Oil Pressure Warning Light
This light indicates low engine oil pres-
sure. The light should turn on momen-
tarily when the engine is started. If the light turns
on while driving, stop the vehicle and shut off
the engine as soon as possible. A chime will
sound when this light turns on.
• Do not operate the vehicle until the cause is
corrected. This light does not show how
much oil is in the engine. The engine oil level
must be checked under the hood.
• Charging System Light
This light shows the status of the elec-
trical charging system. The light should
come on when the ignition switch is
first turned ON and remain on briefly as a bulb
check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-
essential electrical devices or increase engine
speed (if at idle). If the charging system light
remains on, it means that the vehicle is experi-
encing a problem with the charging system.
175

Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
•If jump starting is required, refer to “Jump
Starting Procedures” in “What To Do In
Emergencies”.
• Electronic Throttle Control (ETC) Light
This light informs you of a problem
with the Electronic Throttle Control
(ETC) system. The light will come
on when the ignition is first turned
ON and remain on briefly as a bulb
check. If the light does not come on during
starting, have the system checked by an autho-
rized dealer.
• 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. How-
ever, see an authorized 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 per-
formance, an elevated/rough idle or engine
stall and your vehicle may require towing.
• Engine Temperature Warning Light
This light warns of an overheated en-
gine condition. As temperatures rise
and the gauge approaches H,this in-
dicator will illuminate and a single chime will
sound after reaching a set threshold. Further
overheating will cause the temperature gauge
to pass H,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 vehicle. If the tem-
perature 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. •
Transmission Temperature Light
This light indicates that there is
excessive transmission fluid tem-
perature that might occur with se-
vere usage such as trailer towing. It
may also occur when operating the
vehicle in a high torque converter slip condition,
such as 4-wheel-drive operation (e.g., snow
plowing, off- road operation). If this light comes
on, stop the vehicle and run the engine at idle or
faster, with the transmission in NEUTRAL until
the light goes off.
CAUTION!
Continuous driving with the Transmission
Temperature Indicator illuminated will even-
tually cause severe transmission damage or
transmission failure.

If you stall or begin to lose forward motion
while climbing a steep hill, allow your vehicle to
come to a stop and immediately apply the
brakes. Restart the engine, and shift into RE-
VERSE. Back slowly down the hill, allowing the
compression braking of the engine to help regu-
late your speed. If the brakes are required to
control vehicle speed, apply them lightly and
avoid locking or skidding the tires.
WARNING!
If the engine stalls, you lose forward motion,
or cannot make it to the top of a steep hill or
grade, never attempt to turn around. To do so
may result in tipping and rolling the vehicle.
Always back carefully straight down a hill in
REVERSE gear. Never back down a hill in
NEUTRAL using only the brake.Remember, never drive diagonally across a
hill always drive straight up or down.
If the wheels start to slip as you approach the
crest of a hill, ease off the accelerator and
maintain forward motion by turning the front
wheels slowly. This may provide a fresh “bite”
into the surface and will usually provide traction
to complete the climb.Traction DownhillShift the transmission into a low gear, and the
transfer case into 4WD LOW range. Let the
vehicle go slowly down the hill with all four
wheels turning against engine compression
drag. This will permit you to control the vehicle
speed and direction.
When descending mountains or hills, repeated
braking can cause brake fade with loss of
braking control. Avoid repeated heavy braking
by downshifting the transmission whenever
possible.
After Driving Off-RoadOff-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to check
for damage. That way you can get any problems
taken care of right away and have your vehicle
ready when you need it.
•
Completely inspect the underbody of your ve-
hicle. Check tires, body structure, steering,
suspension, and exhaust system for damage.
•
Inspect the radiator for mud and debris and
clean as required.
• Check threaded fasteners for looseness, par-
ticularly on the chassis, drivetrain compo-
nents, steering, and suspension. Retighten
them, if required, and torque to the values
specified in the Service Manual.
• Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.
247

•After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the radia-
tor, fan, brake rotors, wheels, brake linings,
and axle yokes inspected and cleaned as
soon as possible.
WARNING!
Abrasive material in any part of the brakes
may cause excessive wear or unpredictable
braking. You might not have full braking
power when you need it to prevent a colli-
sion. If you have been operating your vehicle
in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driv-
ing in mud, slush or similar conditions, check
the wheels for impacted material. Impacted
material can cause a wheel imbalance and
freeing the wheels of it will correct the
situation.
FUEL SAVER TECHNOLOGY
5.7L ENGINE ONLY – IF
EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine’s eight cylinders
during light load and cruise conditions. The
system is automatic with no driver inputs or
additional driving skills required.
NOTE:
This system may take some time to return to
full functionality after a battery disconnect.
POWER STEERING
3.6L And 5.7L EngineThe standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost. If for some reason the power assist is inter-
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will ob-
serve a substantial increase in steering effort,
especially at very low vehicle speeds and dur-
ing parking maneuvers.
NOTE:
•
Increased noise levels at the end of the
steering wheel travel are considered nor-
mal and do not indicate that there is a
problem with the power steering system.
• Upon initial start-up in cold weather, the
power steering pump may make noise for
a short amount of time. This is due to the
cold, thick fluid in the steering system.
This noise should be considered normal,
and it does not in any way damage the
steering system.
