MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane. Gaso-
lines blended with MMT offer no performance advantage
beyond gasolines of the same octane number without
MMT. Gasolines blended with MMT reduce spark plug
life and reduce emission system performance in some
vehicles. The manufacturer recommends that gasolines
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
or not his/her gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada because MMT can be used at higher
levels than are allowed in the United States. MMT is
prohibited in Federal and California reformulated gaso-
lines.
Materials Added to Fuel
All gasoline sold in the United States and Canada is
required to contain effective detergent additives. The use
of additional detergents or other additives is not needed
under normal conditions.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
150 STARTING AND OPERATING

•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 your dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers are not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives are not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
STARTING AND OPERATING 151

•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Keep the trunk/liftgate closed when driving your
vehicle to prevent carbon monoxide and other poison-
ous exhaust gases from entering the vehicle.
ADDING FUEL
The fuel tank filler tube has a restricting door about 2
inches (50mm) inside the opening. If using a portable
container, it should have a flexible nozzle long enough to
force open the restricting door.
WARNING!
Remove the fuel tank filler tube cap (gas cap) slowly
to prevent fuel spray from the filler neck that may
cause injury. The volatility of some gasolines may
cause a buildup of pressure in the fuel tank that may
increase while you drive the vehicle. This pressure
can result in a spray of gasoline and/or vapors when
you remove the cap from a hot vehicle. Removing the
cap slowly allows the pressure to vent and prevents
fuel spray. Never have any smoking materials lit in
or near the vehicle when the fuel tank filler tube cap
(gas cap) is removed or when filling the tank. Never
fill the gas tank while the engine is running.

HAZARD WARNING FLASHER
The flasher switch is on the top of the steering
column, just behind the steering wheel. Depress
the flasher button and all front and rear directional
signals will flash. Depress the flasher button again to turn
the flashers off.Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed.
NOTE:With extended use, the flasher may run down
your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways —Slow down and use the highest
gear possible.
•In city traffic —While stopped, put the transmission
in neutral, but do not increase engine idle speed.
Hazard Flasher Switch
156 WHAT TO DO IN EMERGENCIES

•In city traffic—While moving, shift into the highest
gear possible to reduce engine RPM.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the cooling system and turning off the A/C removes this
heat. You can also turn the Temperature control to
maximum heat, the Mode control to floor, and the fan
control to High. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the cooling system.WARNING!
A hot cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant.
If your temperature gauge pointer is in the red area,
turn off the engine immediately. You may want to
call a service center for service. If you decide to look
under the hood yourself, see Section 7 of this
manual. Follow the warnings under the Radiator
Cap paragraph.

JUMP-STARTING PROCEDURES
WARNING!
•Do not attempt to push or tow your vehicle to get
it started. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite
and damage the converter and vehicle. If the
vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly, so
follow this procedure carefully.
•Take care to avoid the radiator cooling fan and
accessory drive whenever the hood is raised. You
can be hurt by the moving components.
WARNING!
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Don’t lean over battery when attaching
clamps or allow the clamps to touch each other. If
acid splashes in eyes or on skin, flush contami-
nated area immediately with large quantities of
water.
•A battery generates hydrogen gas that is flam-
mable and explosive. Keep flame or spark away
from the top of the battery. Do not use a booster
battery or any other booster source with an output
that exceeds 12 volts.
158 WHAT TO DO IN EMERGENCIES

The battery is located under the battery access panel
inside the rear compartment on the left side. Remote
battery terminals are located in the engine compartment
for jump starting.
