76 GETTING TO KNOW YOUR INSTRUMENT PANEL
Instrument Cluster Descriptions
1. Speedometer• Indicates vehicle speed.
2. Fuel Gauge
• The pointer shows the level of fuel in the fuel tankwhen 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.
3. Temperature Gauge

• The temperature gauge shows engine coolant tempera-ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.

• The pointer 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. If you decide to look under the hood
yourself, refer to “Cooling System Pressure Cap” in
“Servicing And Maintenance” and follow the warnings
under the Cooling System Pressure Cap paragraph.
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 remains on the “H,” turn
the engine off immediately and call an authorized dealer
for service.

182 STARTING AND OPERATING
NOTE:
• Tighten the fuel filler cap until you hear a “clicking”sound. This is an indication that the fuel filler cap is prop -
erly tightened.
• If the gas cap is not tightened properly, the MIL may come on. Be sure the gas cap is tightened every time the vehicle
is refueled.
VEHICLE LOADING
As required by National Highway Traffic Safety Administra -
tion regulations, your vehicle has a certification label affixed
to the driver's side door or B-Pillar.
If seats are removed for carrying cargo, do not exceed the
specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a Vehicle Certification Label affixed to the
drivers side B-Pillar or the rear of the driver’s door.
The label contains the following information:
• Name of manufacturer
• Month and year of manufacture
• Gross Vehicle Weight Rating (GVWR)
• Gross Axle Weight Rating (GAWR) front
• Gross Axle Weight Rating (GAWR) rear
• Vehicle Identification Number (VIN)
• Type of vehicle
• Month, Day, and Hour of manufacture (MDH)
The bar code allows a computer scanner to read the VIN.
• 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.
CAUTION!
• Damage to the fuel system or emissions control system could result from using an improper fuel tank filler
tube cap. A poorly fitting cap could let impurities into
the fuel system and may cause the “Malfunction Indi -
cator Light (MIL)” to turn on, due to fuel vapors
escaping from the system.
• To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.

FUEL REQUIREMENTS
2.4L Engine
All available gasoline engines are designed to meet
all emissions regulations and provide excellent fuel
economy and performance when using high quality
unleaded “regular” gasoline having a octane rating of 87
using the (R+M)/2 method. The use of premium gasoline is
not recommended, as it will not provide any benefit over
regular gasoline in these engines.
While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a cause
for concern. However, if the engine is heard making a heavy
knocking sound, see your dealer immediately. Use of gaso -
line 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 considering
service for the vehicle.
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
performance and durability of engine and fuel system
components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen -
ates such as ethanol.
CAUTION!

DO NOT use E-85, 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 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).

298 TECHNICAL SPECIFICATIONS
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
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.
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. 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 gaso -
line retailer whether the gasoline contains MMT. MMT is
prohibited in Federal and California reformulated gasoline.
