service JEEP WRANGLER 2015 Owners Manual

WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags,
seat belt pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer imme-
diately. Also, have the Occupant Restraint Controller
System serviced as well.
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 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 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 ignition is placed in the “OFF” position.
• Turn on the interior lights, which remain on as long as
the battery has power or until the ignition is placed in
the “OFF” position.
• Unlock the doors automatically.
System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition must be changed
from ignition START or ON/RUN to ignition OFF.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71

•The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
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 protec-
tion. Have an authorized dealer service the air bag
system immediately.

WARNING!(Continued)
modify the front bumper, vehicle body structure, or
add aftermarket side steps or running boards.
• 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 properly if modifications are made.
Take your vehicle to an authorized dealer for any
air bag system service. If your seat, including your
trim cover and cushion, needs to be serviced in any
way (including removal or loosening/tightening of
seat attachment bolts), take the vehicle to your
authorized dealer. Only manufacturer approved
seat accessories may be used. If it is necessary to
modify the air bag system for persons with dis-
abilities, 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 or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. 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 pushing the accelera-
tor and/or brake pedal; and,
• How fast the vehicle was traveling.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 inoper-
able.
Floor Mat Safety Information
Always use floor mats designed to fit the footwell 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.

NOTE:
•
The emergency number dialed is based on the country
where the vehicle is purchased (911 for the U.S. and
Canada and 060 for Mexico). The number dialed may not
be applicable with the available mobile service and area.
• If supported, this number may be programmable on
some systems. To do this, push the Phone

indicate that the parking brake is applied, that the brake
fluid level is low, or that there is a problem with the
anti-lock brake system 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 capac-
ity 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.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.

UNDERSTANDING YOUR INSTRUMENT PANEL 309

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.

WARNING!(Continued)
locked in PARK, securing the vehicle against un-
wanted movement.
• When leaving the vehicle, always remove the igni-
tion key from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the transmission gear selector.
• Do not leave the ignition key in or near the vehicle
(or in a location accessible to children). A child
could operate power windows, other controls, or
move the vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/
OFF (key removal) position. The key can only be re-
moved from the ignition when the ignition is in the
LOCK/OFF position, and once removed the transmission
is locked in PARK.
NOTE: If a malfunction occurs, the system will trap the
key in the ignition switch to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission

worn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
•
Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.
• 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.
