F
USES
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.
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.
CAUTION!
If it is necessary to wash the engine
compartment, take care not to directly hit the
fuse box or the windshield wiper motors with
water.

Tire Markings
Tire Markings
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
-
rary emergency use only. Temporary high pres
-
sure compact spare tires have the letter “T” or
“S” molded into the sidewall preceding the size
designation. Example: T145/80D18 103M.
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.

P = Passenger car tire size based on US design standards, or
". blank. " = Passenger car tire based on European design standards, or
LT = Light truck tire based on US design standards, or
T or S = Temporary spare tire or
31 = Overall diameter in inches (in)
215, 235, 145 = Section width in millimeters (mm)
65, 85, 80 = Aspect ratio in percent (%)
Ratio of section height to section width of tire, or
10.5 = Section width in inches (in)
R = Construction code
"R" means radial construction, or
"D" means diagonal or bias construction
15, 16, 18 = Rim diameter in inches (in)
Service Description:
95 = Load Index
A numerical code associated with the maximum load a tire can carry
H = Speed Symbol
A symbol indicating the range of speeds at which a tire can carry a load corresponding to its load index under certain operating conditions
The maximum speed corresponding to the speed symbol should only be achieved under specified operating conditions (i.e., tire pressure, vehicle loading,
road conditions, and posted speed limits)

SERVICING AND MAINTENANCE
Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire; however, the date code may only be on one side. Tires with white sidewalls will have the full TIN, including
the date code, located on the white sidewall side of the tire. Look for the TIN on the outboard side of black sidewall tires as mounted on the vehicle. If the TIN is
not found on the outboard side, then you will find it on the inboard side of the tire.
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:
XL = Extra load (or reinforced) tire, or
LL = Light load tire or
C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load – Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure – Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire
EXAMPLE:
EXAMPLE:
DOT MA L9 ABCD 0301
DOT = Department of Transportation
This symbol certifies that the tire is in compliance with the US Department of Transportation tire safety standards and is approved for highway use
MA = Code representing the tire manufacturing location (two digits)
L9 = Code representing the tire size (two digits)
ABCD = Code used by the tire manufacturer (one to four digits)
03 = Number representing the week in which the tire was manufactured (two digits)
03 means the 3rd week
