2023 DODGE DURANGO check engine

SERVICING AND MAINTENANCE271
The fuses protect electrical systems against
excessive 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 using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.
Blade Fuses

Underhood Fuses
The Power Distribution Center is located in the
engine compartment near the battery jump start
posts. This center contains cartridge fuses, micro
fuses, relays, and circuit breakers. A description of
each fuse and component may be stamped on the
inside cover, otherwise the cavity number of each
fuse is stamped on the inside cover that
corresponds to the following chart.If the replaced fuse blows again, contact an
authorized dealer.
If a general protection fuse for safety systems
(air bag system, braking system), power unit
systems (engine system, transmission
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 SPECIFICATIONS303
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.

Wheel Mounting Surface

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 half way).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by an authorized
dealer or service station.
After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly tightened.
Torque Patterns

FUEL REQUIREMENTS
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 a dealer immediately. Use of
gasoline with a lower than recommended octane
number 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
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.
This engine is designed to meet all
emissions regulations and provide
optimum fuel economy and
performance when using high quality
unleaded regular gasoline having a posted octane
number of 87 as specified by the (R+M)/2 method.
The use of higher octane premium gasoline is not
required, as it will not provide any benefit over
regular gasoline in these engines.
5.7L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.
This engine is designed to meet all
emissions regulations and provide
satisfactory fuel economy and
performance when using high-quality
unleaded gasoline having an octane range of 87 to
89 as specified by the (R+M)/2 method. The use of
89 octane plus gasoline is recommended for
optimum performance and fuel economy.
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.
