FUSES

General Information

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

Power Distribution Center

The Power Distribution Center is located in the

engine compartment near the battery. 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.

WARNING!



When replacing a blown fuse, always use an

appropriate replacement fuse with the same

amp rating as the original fuse. Never replace

a fuse with another fuse of higher amp rating.

The use of a fuse with a rating other than indi

-

cated may result in a dangerous electrical

system overload. If a properly rated fuse

continues to blow, it indicates a problem in the

circuit that must be corrected. Never replace a

blown fuse with metal wires or any other mate

-

rial. Do not place a fuse inside a circuit

breaker cavity or vice versa. Failure to use

proper fuses may result in serious personal

injury, fire and/or property damage.



Before replacing a fuse, make sure that the

ignition is off and that all the other services

are switched off and/or disengaged.



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.

CAUTION!

If it is necessary to wash the engine

compartment, take care not to directly hit the

fuse box, and the windshield wiper motors with

water.

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.



If it is necessary to wash the engine compart

-

ment, take care not to directly hit the fuse box,

and the windshield wiper motors with water.

NOTE:



P (Passenger) — Metric tire sizing is based on US

design standards. P-Metric tires have the letter

“P” molded into the sidewall preceding the size

designation. Example: P215/65R15 95H.



European — Metric tire sizing is based on Euro

pean design standards. Tires designed to this

standard have the tire size molded into the side

wall beginning with the section width. The letter

"P" is absent from this tire size designation.

Example: 215/65R15 96H.



LT (Light Truck) — Metric tire sizing is based on

US design standards. The size designation for

LT-Metric tires is the same as for P-Metric tires

except for the letters “LT” that are molded into

the sidewall preceding the size designation.

Example: LT235/85R16.



Temporary spare tires are designed for tempo

High flotation tire sizing is based on US design

standards and it begins with the tire diameter

molded into the sidewall.

Example: 31x10.5 R15 LT.
