Instrument Cluster Descriptions
1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Instrument Cluster Display •The instrument cluster display features a driver-
interactive display. Refer to “Instrument Cluster Dis-
play” in “Getting To Know Your Instrument Panel” for
further information.
3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The fuel gauge shows the level of fuel in the fuel tank
when the 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 will likely indicate a higher temperature
when driving in hot weather or up mountain grades. It
should not be allowed to exceed the upper limits of the
normal operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats.
130 GETTING TO KNOW YOUR INSTRUMENT PANEL

•Tighten the gas cap about one quarter 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 MIL will
come on. Be sure the gas cap is tightened every time the
vehicle is refueled.
CAUTION!
• Damage to the fuel system or emission control sys-
tem could result from using an improper fuel filler
cap. A poorly fitting cap could let impurities into the
fuel system. Also, a poorly fitting aftermarket cap
can cause the “Malfunction Indicator Light (MIL)” to
illuminate, due to fuel vapors escaping from the
system.
• A poorly fitting fuel filler cap may cause the MIL to
turn on.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
• If fuel is spilled on surface on the paint, clear it
immediately to avoid damage the paint.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the MIL to turn on.
• 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.

Reformulated Gasoline
Many areas of the country require the use of cleaner burning
gasoline referred to as “Reformulated Gasoline”. Reformu-
lated gasoline contains oxygenates and are specifically
blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Properly
blended reformulated gasoline will provide improved per-
formance and durability of engine and fuel system compo-
nents.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen-
ates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gasoline
containing more than 15% ethanol (E-15). Use of these
blends may result in starting and drivability problems,
damage critical fuel system components, cause emis-
sions to exceed the applicable standard, and/or cause
the “Malfunction Indicator Light” to illuminate. Please
observe pump labels as they should clearly communi-
cate 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 gasoline
containing up to 15% ethanol (E-15). Gasoline with higher
ethanol content may void the New Vehicle Limited War-
ranty.
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.

CNG And LP Fuel System Modifications
Modifications that allow the engine to run on compressed
natural gas (CNG) or liquid propane (LP) may result in
damage to the engine, emissions, and fuel system compo-
nents. Problems that result from running CNG or LP are
not the responsibility of the manufacturer and may void or
not be covered under the New Vehicle Limited Warranty.
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. Gaso-
line 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 that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.Designated TOP TIER Detergent Gaso-
line contains a higher level of detergents
to further aide in minimizing engine
and fuel system deposits. When avail-
able, the usage of Top Tier Detergent
gasoline is recommended. Visit
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.
