INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge/Fuel Door ReminderWhen the ignition switch is in the ON/RUN
position, the pointer will show the level of fuel
remaining in the fuel tank. The fuel pump
symbol points to the side of the vehicle where
the fuel door is located.
2. Charging System Light This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned to ON/RUN and remain on
briefly as a bulb check. If the light stays on or comes on
while driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer. If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
3. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped and the
shift lever is placed in the NEUTRAL position. The light
should turn off. If the light remains lit with the engine
running, your vehicle will usually be drivable; however,
see an authorized dealer for service as soon as possible. If
the light is flashing when the engine is running, imme-
diate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and
your vehicle may require towing. The light will come on
when the ignition is first turned to ON/RUN and remain

Tip Start
Do notpress the accelerator. Turn the ignition switch to
the START position and release it as soon as the starter
engages. The starter motor will continue to run, and it
will disengage automatically when the engine is running.
If the engine fails to start, the starter will disengage
automatically in 10 seconds. If this occurs, turn the
ignition switch to the LOCK position, wait 10 to 15 sec-
onds, then repeat the “Normal Starting” procedure.
Normal Starting
Normal starting of either a cold or a warm engine does
not require pumping or pressing the accelerator pedal.
Simply turn the ignition switch to the START position
and release when the engine starts. If the engine fails to
start within 15 seconds, turn the ignition switch to the
OFF position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. 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
another vehicle. This type of start can be dangerous if
done improperly, so follow the procedure carefully.
Refer to “Jump Starting” in “What To Do In Emer-
gencies” for further information.
Extreme Cold Weather (Below –20°F or 29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
292 STARTING AND OPERATING

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as Ethanol. Fuels blended with oxygenates
may be used in your vehicle.
CAUTION!
DO NOT use gasoline containing Methanol or gaso-
line containing more than 10% Ethanol. Use of these
blends may result in starting and driveability prob-
lems, damage critical fuel system components, cause
emissions to exceed the applicable standard, and/or
cause the “Malfunction Indicator Light” to illumi-
nate. Pump labels should clearly communicate if a
fuel contains greater than 10% Ethanol.
Problems that result from using gasoline containing
Methanol or gasoline containing more than 10% Ethanol
are not the responsibility of the manufacturer and may
not be covered under warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s 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 driveability
•increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•change the engine oil and oil filter
•disconnect and reconnect the battery

STARTING AND OPERATING 359

•drain the fuel tank (see your authorized dealer)
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
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. It is even more important to
look for gasoline without MMT in Canada, because MMT
can be used at levels higher than those allowed in the
United States. MMT is prohibited in Federal and Califor-
nia reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.
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 perfor-
mance and damage the emissions control system. (Continued)
360 STARTING AND OPERATING

CAUTION!
•Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler cap (gas cap). A poorly fitting cap could
let impurities into the fuel system.
•A poorly fitting gas cap may cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.
•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 gas cap is removed or the
tank is being filled.(Continued)
WARNING! (Continued)
•Never add fuel when the engine is running. This is
in violation of most state and Federal fire regula-
tions 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.
NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
•Tighten the gas cap about 1/4 turn until you hear one
click. This is an indication that cap is properly tight-
ened.
•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.

•When installing the IPM cover, it is important to
ensure the cover is properly positioned and fully
latched. Failure to do so may allow water to get
into the IPM, and possibly result in an electrical
system failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
