warning light JEEP WRANGLER 2020 Owner handbook (in English)

The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system is
designed to be maintenance free, if any of the
following occurs, have an authorized dealer
service the air bag system immediately.
• The Air Bag Warning Light does not come
on during the four to eight seconds when
the ignition switch is first in the ON/RUN
position.
• The Air Bag Warning Light remains on after
the four to eight-second interval.
• The Air Bag Warning Light comes on inter-
mittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant Restraint Controller (ORC) may also
be disabled. In this condition the air bags
may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air
bag system immediately.WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if
it comes on as you drive, have an autho-
rized dealer service the air bag system
immediately.
Front Air Bags
This vehicle has front air bags and lap/
shoulder belts for both the driver and front
passenger. The front air bags are a supple-
ment to the seat belt restraint systems. The
driver front air bag is mounted in the center of
the steering wheel. The passenger front air
bag is mounted in the instrument panel,
above the glove compartment. The words
“SRS AIRBAG” or “AIRBAG” are embossed
on the air bag covers.
WARNING!
• Being too close to the steering wheel or
instrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably extending

Seat belts are necessary for your protection in
all collisions, and also are needed to help
keep you in position, away from an inflating
air bag.
When the ORC detects a collision requiring
the front air bags, it signals the inflator units.
A large quantity of non-toxic gas is generated
to inflate the front air bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air
bags inflate to their full size. The front air
bags fully inflate in less time than it takes to
blink your eyes. The front air bags then
quickly deflate while helping to restrain the
driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the
knees of the driver and front passenger, and
position the front occupants for improved
interaction with the front air bags.
WARNING!
• Do not drill, cut, or tamper with the knee
impact bolsters in any way.
• Do not mount any accessories to the
knee impact bolsters such as alarm
lights, stereos, citizen band radios, etc.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags
(SABs) (if equipped)
Your vehicle may be equipped with Supple-
mental Seat-Mounted Side Air Bags (SABs).
If your vehicle is equipped with Supplemen-
tal Seat-Mounted Side Air Bags (SABs),
please refer to the information below.
Supplemental Seat-Mounted Side Air Bags
(SABs) are located in the outboard side of the
front seats. The SABs are marked with “SRS
AIRBAG” or “AIRBAG” on a label or on the
seat trim on the outboard side of the seats.The SABs (if equipped with SABs) may help
to reduce the risk of occupant injury during
certain side impacts, in addition to the injury
reduction potential provided by the seat belts
and body structure.
When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim
cover. The inflating SAB deploys through the
seat seam into the space between the occu-
pant and the door. The SAB moves at a very
high speed and with such a high force that it
could injure occupants if they are not seated

WARNING!
some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt
even though you have Side Air Bags.
NOTE:
Air bag covers may not be obvious in the
interior trim, but they will open during air bag
deployment.
Air Bag System Components
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon-
necting wiring associated with electrical Air
Bag System Components listed below:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags• Front and Side Impact Sensors
• Seat Belt Pretensioners
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may occur:
• The air bag material may sometimes cause
abrasions and/or skin reddening to the oc-
cupants as the air bags deploy and unfold.
The abrasions are similar to friction rope
burns or those you might get sliding along a
carpet or gymnasium floor. They are not
caused by contact with chemicals. They are
not permanent and normally heal quickly.
However, if you haven’t healed significantly
within a few days, or if you have any blis-
tering, see your doctor immediately.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that gen-erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’s instructions for cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.
97

NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion 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 Sys-
tem 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
pressed. The hazard lights can be deacti-
vated by pressing 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 Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully 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.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper right side of the
instrument panel. Do not modify the
front bumper, vehicle body structure, or
add aftermarket side steps or running
boards.
WARNING!
• It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-
ing removal or loosening/tightening of
seat attachment bolts), take the vehicle
to your authorized dealer. Only manufac-
turer approved seat accessories may be
used. If it is necessary to modify the air
bag system for persons with disabilities,
contact your authorized dealer.
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

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 seat belt system periodically,
checking for cuts, frays, and loose parts. Dam-
aged parts must be replaced immediately. Do
not disassemble 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 web-
bing, etc.). If there is any question regarding
seat belt or retractor condition, replace the
seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for
four to eight seconds as a bulb check when the
ignition switch is first turned to ON/RUN. If the
light is either not on during starting, stays on, or
turns on while driving, have the system in-spected at an authorized dealer as soon as
possible. This light will illuminate with a single
chime when a fault with the Air Bag Warning
Light has been detected, it will stay on until the
fault is removed. If the light comes on intermit-
tently or remains on while driving, have an
authorized dealer service the vehicle immedi-
ately. Refer to “Occupant Restraint Systems” in
“Safety” for further information.
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 your
vehicle. Only use a floor mat that does not
interfere with the operation of the pedal as-
semblies. Only use a floor mat that is securely
attached using the floor mat fasteners so it
cannot slip out of position and interfere with
the pedal assemblies or impair safe operation
of your vehicle in other ways.
WARNING!
An improperly attached, damaged, folded,
or stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to in-
terfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle
control. To prevent SERIOUS INJURY or
DEATH:
• ALWAYS securely attach
your floor
mat using the floor mat fasteners. DO
NOT install your floor mat upside down
or turn your floor mat over. Lightly pull to
confirm mat is secured using the floor
mat fasteners on a regular basis.
• ALWAYS REMOVE THE EXISTING
FLOOR MAT FROM THE VEHICLE
before installing any other floor mat.
NEVER install or stack an additional
floor mat on top of an existing floor mat.
• ONLY install floor mats designed to fit
your vehicle. NEVER install a floor mat
that cannot be properly attached and
secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA
approved floor mat for the specific
make, model, and year of your vehicle.
113

WARNING!
• ONLY use the driver’s side floor mat on
the driver’s side floor area. To check for
interference, with the vehicle properly
parked with the engine off, fully depress
the accelerator, the brake, and the
clutch pedal (if present) to check for
interference. If your floor mat interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
• ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
• ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area
when the vehicle is moving. Objects can
become trapped under accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
• NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These ob-
jects could change the position of the
floor mat and may cause interference
WARNING!
with the accelerator, brake, or clutch
pedals.
• If the vehicle carpet has been removed
and re-installed, always properly attach
carpet to the floor and check the floor
mat fasteners are secure to the vehicle
carpet. Fully depress each pedal to
check for interference with the accelera-
tor, brake, or clutch pedals then re-
install the floor mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
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 thetread 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 proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected imme-
diately.

STARTING THE ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belts.
WARNING!
• When exiting the vehicle, always remove
the key fob from the ignition and lock
your vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
• Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children. A child could operate power
windows, other controls, or move the
vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
WARNING!
heat build-up may cause serious injury
or death.
Manual Transmission — If Equipped
Apply the parking brake, place the gear se-
lector in NEUTRAL, and press the clutch
pedal before starting the vehicle. This vehicle
is equipped with a clutch interlocking igni-
tion system. It will not start unless the clutch
pedal is pressed to the floor.
Four-Wheel Drive Models Only
In 4L mode, this vehicle will start regardless
of whether or not the clutch pedal is pressed
to the floor. This feature enhances off-road
performance by allowing the vehicle to start
when in 4L without having to press the clutch
pedal. The “4WD Low Indicator Light” will
illuminate when the transfer case has been
shifted into this mode.
Automatic Transmission — If Equipped
Start the vehicle with the gear selector in the
PARK position (vehicle can also be started in
NEUTRAL). Apply the brake before shifting
to any driving range.
Normal Starting — Gasoline Engine
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
Cycle the ignition switch to the START posi-
tion and release when the engine starts. If the
engine fails to start within 10 seconds, cycle
the ignition switch to the LOCK/OFF position,
wait 10 to 15 seconds, then repeat the “Nor-
mal Starting” procedure.
Extreme Cold Weather (Below –22°F Or
−30°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your au-
thorized dealer) is recommended.
117

ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contrib-
utes to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental
and should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. For
the recommended viscosity and quality
grades, refer to “Dealer Service” in “Servic-
ing And Maintenance”.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as a problem.
PARKING BRAKE
Before exiting the vehicle, make sure that the
parking brake is fully applied. Also, be cer-
tain to leave an automatic transmission in
PARK, or manual transmission in REVERSE
or FIRST gear.
The parking brake lever is located in the
center console. To apply the parking brake,
pull the lever up as firmly as possible. To
release the parking brake, pull the lever up
slightly, push the center button, then lower
the lever completely.When the parking brake is applied with the
ignition switch ON, the “Brake Warning Light”
in the instrument cluster will illuminate.
NOTE:
• When the parking brake is applied and the
automatic transmission is placed in gear,
the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will
sound to alert the driver. Fully release the
parking brake before attempting to move
the vehicle.
Parking Brake Lever

• This light only shows that the parking brake
is applied. It does not show the degree of
brake application.
When parking on a hill, it is important to turn
the front wheels toward the curb on a down-
hill grade and away from the curb on an uphill
grade. For vehicles equipped with an auto-
matic transmission, apply the parking brake
before placing the gear selector in PARK,
otherwise the load on the transmission lock-
ing mechanism may make it difficult to move
the gear selector out of PARK. The parking
brake should always be applied whenever the
driver is not in the vehicle.
WARNING!
• Never use the PARK position on an au-
tomatic transmission as a substitute for
the parking brake. Always apply the
parking brake fully when parked to guard
WARNING!
against vehicle movement and possible
injury or damage.
• When exiting the vehicle, always remove
the key fob from the ignition and lock
your vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children. A child could operate power
windows, other controls, or move the
vehicle.
• Be sure the parking brake is fully disen-
gaged before driving; failure to do so can
lead to brake failure and a collision.
WARNING!
• Always fully apply the parking brake
when leaving your vehicle or it may roll
and cause damage or injury. Also, be
certain to leave an automatic transmis-
sion in PARK, a manual transmission in
REVERSE or first gear. Failure to do so
may cause the vehicle to roll and cause
damage or injury.
CAUTION!
If the “Brake Warning Light” remains on
with the parking brake released, a brake
system malfunction is indicated. Have the
brake system serviced by an authorized
dealer immediately.
