1. Tachometer
• Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Electronic Vehicle Information Center (EVIC)
• When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center
(EVIC) messages. Refer to “Electronic Vehicle Infor-
mation Center” in “Understanding Your Instrument
Panel” for further information.
3. Speedometer
• Indicates vehicle speed. 4. Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
• The fuel pump arrow 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 or up moun-
tain grades. It should not be allowed to exceed the
upper limits of the normal operating range.234 UNDERSTANDING YOUR INSTRUMENT PANEL

1. Tachometer
• Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Voltmeter
• When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay
within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
NOTE: The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize. 3. Oil Pressure Gauge
• The pointer should always indicate some oil pres-
sure when the engine is running. A continuous high
or low reading under normal driving conditions may
indicate a lubrication system malfunction. Immedi-
ate service should be obtained from an authorized
dealer.
4. Speedometer
• Indicates vehicle speed.
5. Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
• The fuel pump arrow symbol points to the
side of the vehicle where the fuel door is located. 4UNDERSTANDING YOUR INSTRUMENT PANEL 237

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 5STARTING AND OPERATING 499

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 gasolines500 STARTING AND OPERATING

NOTE: Tighten the gas cap ¼ turn until you hear one
click. This is an indication that the cap is properly
tightened.
If the gas cap is not tightened properly, the Malfunction
Indicator Light will come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
WARNING!A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator will display in the EVIC/DID telltale display area. Refer
to “Electronic Vehicle Information Center (EVIC)/Driver
Information Display (DID) in “Understanding Your In-
strument Panel” for further information. Tighten the fuel
filler cap properly and push the RIGHT button to turn off
the message. If the problem continues, the message will
appear the next time the vehicle is started.

Certification Label
As required by National Highway Traffic Safety Admin-
istration regulations, your vehicle has a certification label
affixed to the driver’s side door or pillar.
This label contains the month and year of manufacture,
