Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine and automatic transmission control systems. The
light will illuminate when the ignition is in the ON position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate
the light after engine start. The vehicle should be serviced if the light stays on through sev-
eral typical driving styles. In most situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the MIL may flash to alert serious conditions that could lead to
immediate loss of power or severe catalytic converter damage. The vehicle should be ser-
viced as soon as possible if this occurs.

Loose Fuel Filler Cap Indicator Light — If Equipped
Yellow TelltaleLight What It Means
Loose Fuel Filler Cap Indicator Light
This light will illuminate when fuel filler cap is loose. Properly close the filler cap to disen-
gage the light. If the light does not turn off, please see your authorized dealer.
Transmission Temperature Indicator Light
Red Telltale
Light What It Means
Transmission Temperature Indicator Light
This light indicates that the transmission fluid temperature is running hot. This may occur with
severe usage, such as trailer towing. If this light turns on, safely pull over and stop them ve-
hicle. Then, shift the transmission into NEUTRAL and run the engine at idle or faster until the
light turns off.

CAUTION!(Continued)
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your
vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the TPMS sensor. NOTE:
•
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underin-
flation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light”.

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
(Continued)
WARNING! (Continued)
time the vehicle is raised. Have any abnormal
conditions repaired promptly. Until repaired, drive
with all side windows fully open.
FLEXIBLE FUEL (2.4L ENGINE ONLY) — IF
EQUIPPED
E-85 General Information
The information in this section is unique for Flexible Fuel
vehicles only. These vehicles can be identified by a
unique fuel filler door label that states Ethanol (E-85) or
Unleaded Gasoline Only and a yellow fuel cap. Please
refer to the other sections of this manual for information
on features that are common between Flexible Fuel and
non-Flexible Fuel powered vehicles.

STARTING AND OPERATING 581

CAUTION!
Only vehicles with the E-85 fuel filler door label or a
yellow gas cap can operate on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% ethanol and 15%
unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smok-
ing materials lit or products that can cause spark in or
near the vehicle when removing the fuel filler tube
cap (gas cap) or filling the tank. Do not use E-85 as a
cleaning agent and never use it near an open flame.
Fuel Requirements
If your vehicle is E-85 compatible, it will operate on
unleaded gasoline with any octane rating, or solely E-85
fuel, or any mixture of these fuels.
For best results, avoid fueling patterns alternating
between E-85 and unleaded gasoline.
When switching fuel types:
•Add 5 gallons (19 liters) or more when refueling.
• Drive the vehicle immediately after refueling for at
least 5 miles (8 km).
Observing these precautions will avoid possible hard
starting and/or driveability problems during warm up.
582 STARTING AND OPERATING

Cruising Range
Because E-85 fuel contains less energy per gallon/liter
than gasoline, an increase in fuel consumption will be
experienced. The miles per gallon (mpg)/kilometers per
liter and the driving range will decrease by approxi-
mately 30%, compared to gasoline operation.
Replacement Parts
All fuel and engine components in your Flexible Fuel
Vehicle (FFV) are designed to be compatible with ethanol.
Ethanol compatible service components are required.
CAUTION!
Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.
Maintenance
CAUTION!
Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and
may affect drivability.
ADDING FUEL
The gas cap is located behind the fuel filler door, on the
passenger side of the vehicle. If the gas cap is lost or
damaged, be sure the replacement cap has been designed
for use with this vehicle.
NOTE:When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door rein-
forcement.
1. Push the fuel filler door release switch (located on the driver ’s side door trim).
584 STARTING AND OPERATING

2. Open the fuel filler door, and remove the fuel fillercap. NOTE:
•
In certain cold conditions, ice may prevent the fuel
door from opening. If this occurs, lightly push on the
fuel door to break the ice buildup and re-release the
fuel door using the inside release button. Do not pry
on the door.
