1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Driver Information Display (DID) Display •When the appropriate conditions exist, this display
shows the Driver Information Display (DID) mes-
sages. Refer to “Driver Information Display (DID)”
in “Understanding Your Instrument Panel” for fur-
ther information.
3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the Keyless Push Button Ignition is in the
ON/RUN position.
The fuel pump symbol
points to the side of the
vehicle where the fuel door is located.
5. Temperature Gauge
•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer

making a heavy knocking sound, see your dealer imme-
diately. Use of gasoline with an octane number lower
than 87 can cause engine failure and may void or not be
covered by 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 consid-
ering service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasoline contains oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide im-
proved performance and durability of engine and fuel
system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gaso-
line containing more than 15% ethanol (E-15). Use of
these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the “Malfunction Indicator Light” to
illuminate. Please observe pump labels as they
should clearly communicate if a fuel contains greater
than 15% ethanol (E-15).
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol

are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited
Warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 15% ethanol (E-15). Gasoline with
higher ethanol content may void the New Vehicle Lim-
ited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (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.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines

CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the “Malfunction Indicator
Light” to turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the
ground while filling.
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door, use the fuel
filler door emergency release located in the trunk.
