2023 JEEP GLADIATOR engine

SERVICING AND MAINTENANCE383
The fuses protect electrical systems against
excessive electrical current.
When a device does not work, you must check the
fuse element inside the blade fuse for a break/
melt.
Also, please be aware that when using power
outlets for an extended period of time with the
engine off, it may result in vehicle battery
discharge.
Blade Fuses

Power Distribution Center (PDC)
The Power Distribution Center is located in the
engine compartment near the battery. This center
contains cartridge fuses, mini fuses, and relays.
The PDC top cover is labeled with each serviceable
fuse/relay location, function, and size.If a general protection fuse for safety systems
(air bag system, braking system), power unit
systems (engine system, gearbox system) or
steering system blows, contact an authorized
dealer.
WARNING!
1 — Fuse Element
2 — Blade Fuse with a good/functional fuse
element
3 — Blade fuse with a bad/not functional fuse
element (blown fuse)
CAUTION!
When installing the power distribution center
cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the power
distribution center and possibly result in an
electrical system failure.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
A-pillar, visible from outside of the vehicle through
the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN plate.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose
normal capability, the remaining system will still
function. However, there will be some loss of
overall braking effectiveness. You may notice
increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off)
the brakes will still function. However, the effort
required to brake the vehicle will be much greater
than that required with the power system
operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/bolt
(do not insert it halfway).

Torque Patterns

After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.
FUEL REQUIREMENTS — GASOLINE ENGINE
While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see an authorized dealer
immediately. Use of gasoline with an octane
number lower than recommended can cause
engine failure and may void the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
3.6L ENGINE
This engine is designed to meet all
emission regulations and provide
excellent fuel economy and performance
when using high-quality unleaded regular
gasoline having an octane rating of 87 as specified
by the (R+M)/2 method. The use of higher octane
premium gasoline will not provide any benefit over
regular gasoline in these engines.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner-burning gasoline referred to as
“reformulated gasoline”. Reformulated gasoline contains oxygenates and are specifically blended
to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will
provide improved performance and durability of
engine and fuel system components.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline
contains a higher level of detergents to
further aide in minimizing engine and
fuel system deposits. When available,
the usage of TOP TIER Detergent Gasoline is
recommended. Visit www.toptiergas.com for a list
of TOP TIER Detergent Gasoline retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials
intended for gum and varnish removal may contain
active solvents or similar ingredients. These can
harm fuel system gasket and diaphragm materials.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.9

GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the
responsibility of the manufacturer and may void
the New Vehicle Limited Warranty.
DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
Non-Flex Fuel Vehicles (FFV) are compatible with
gasoline containing up to 15% ethanol (E-15). Use
of gasoline with higher ethanol content may void
the New Vehicle Limited Warranty. If a Non-FFV vehicle is inadvertently fueled with
E-85 fuel, the engine will have some or all of these
symptoms:
Operate in a lean mode.
OBD II Malfunction Indicator Light on.
Poor engine performance.
Poor cold start and cold drivability.
Increased risk for fuel system component corro
-
sion.
CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid Propane
(LP) may result in damage to the engine,
emissions, and fuel system components. Problems
that result from running CNG or LP are not the
responsibility of the manufacturer and may void
the New Vehicle Limited Warranty.
METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive
that is blended into some gasolines to increase
octane. Gasoline blended with MMT provides no
performance advantage beyond gasoline of the
same octane number without MMT. Gasoline blended with MMT reduces spark plug life and
reduces emissions system performance in some
vehicles. The manufacturer recommends that
gasoline without MMT be used in your vehicle. The
MMT content of gasoline may not be indicated on
the gasoline pump; therefore, you should ask your
gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal law and
California reformulated gasoline.
FUEL SYSTEM CAUTIONS
CAUTION!
DO NOT use E-85, gasoline containing methanol,
or gasoline containing more than 15% ethanol
(E-15). Use of these blends may result in starting
and drivability problems, damage critical fuel
system components, cause emissions to exceed
the applicable standard, and/or cause the
Malfunction Indicator Light to illuminate. Please
observe pump labels as they should clearly
communicate if a fuel contains greater than
15% ethanol (E-15).
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can impair
engine performance and damage the emis
-
sions control system.
An out-of-tune engine, certain fuel or ignition
malfunctions can cause the catalytic
converter to overheat. If you notice a pungent
burning odor or some light smoke, your engine
may be out-of-tune or malfunctioning and may
require immediate service. Contact an autho -
rized dealer for service assistance.
