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 when using power
outlets for extended periods of time with the
engine off may result in vehicle battery discharge.
Blade Fuses

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.
Never replace a blown fuse with metal wires or
any other material. 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.

METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive
that is blended into some gasoline 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 and California
reformulated gasoline.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
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 or 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.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom -
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of the manufac-
turer and may void or not be covered under
the New Vehicle Limited Warranty.
CAUTION!
