Yellow Telltale Indicator Lights
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
several 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
serviced as soon as possible if this occurs.4

disengage. Once this occurs, release the accelerator pedal
and the brake pedal, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure.
Clearing A Flooded Engine (Using ENGINE
START/STOP Button) — Manual Transmission
Only
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weatherproce-
dures, it may be flooded. To clear any excess fuel, press
and hold the clutch pedal, press the accelerator pedal all
the way to the floor and hold it, then push and hold the
ENGINE START/STOP button for no more than 15
seconds. Release the accelerator pedal and the clutch
pedal, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located near the air box.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.

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.
• Keep the trunk closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located behind the fuel filler door on the
left side of the vehicle. Use a finger to pull open the door.
If the gas cap is lost or damaged, be sure the replacement
cap is for use with this vehicle.

STARTING AND OPERATING 465

NOTE:When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap.
• A poorly fitting fuel filler cap could let impurities
into the fuel system.
• A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn on.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.
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)
Fuel Filler Cap
466 STARTING AND OPERATING

WARNING!(Continued)
•Never add fuel to the vehicle when the engine is
running.
• 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 until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn
on if the gas cap is not secured properly. Make sure
that the gas cap is tightened each time the vehicle is
refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will display in the odometer or a
“Check Gascap” message will display in the Driver
Information Display (DID). If this occurs, tighten the fuel
filler cap properly and press the TRIP ODOMETER
button to turn off the message. If the problem continues,
the message will appear the next time the vehicle is
started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL. Refer to “Onboard Diagnostic
System” in “Maintaining Your Vehicle” for further infor-
mation.
