gASCAP
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 display
area. 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.
LoW tirE
When the appropriate condition exists, the odometer
display will toggle between LoW and tirE for three
cycles.
noFUSE
If the vehicle diagnostic system determines that the Igni-
tion Off Draw (IOD) fuse is improperly installed, or
damaged, a “noFUSE” message will display in the odom-
eter display area. For further information on fuses and fuse
locations refer to “Fuses” in “Maintaining Your Vehicle”.
CHAngE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHAngE OIL” message will flash
in the instrument cluster odometer for approximately
12 seconds after a single chime has sounded, to indicate
the next scheduled oil change interval. The engine oil
change indicator system is duty cycle based, which
means the engine oil change interval may fluctuate
dependent upon your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the Trip Odometer button on the instrument
cluster. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure:1. Turn the ignition switch to the ON/RUN position
(do not start the engine).

RUN and remain on, as a bulb check, until the engine is
started. If the vehicle is not ready for emissions testing,
the light will come on when the ignition is first turned to
ON/RUN and remain on for 15 seconds, then blink for
5 seconds, and remain on until the vehicle is started. If
the bulb does not come on during starting, have the
condition investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see an authorized dealer for service as soon
as possible.CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.

22. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or

right of the control panel. Conditioned air will be di-
rected through the outlets selected by the mode control.
A light at the top of the SNOWFLAKE button shows that
the air conditioning is on. Press the button a second time
to turn the air conditioning off.
Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is a
normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.The Mode Control (at the right of the
control panel) can be set in any of the
following positions: NOTE:
To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots.
Recirculation Modes (Panel or Bi-Level )
Select the recirculation modes when
the outside air contains dust, odors,
high humidity, or if rapid cooling is
desired. This feature allows for recir-
culation of interior air only. Air flows
either through the panel outlets or
both the panel and floor outlets to-
gether, depending on which recirculation mode is
selected.
Panel (Fresh Air Modes)
Outside air flows through the outlets located in the
instrument panel.Mode Control

248 STARTING AND OPERATING

Turn the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, turn the key to the OFF position, wait
5 seconds, then repeat the “Normal Starting” procedure.
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 dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.(Continued)
WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission 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 dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be dan-
gerous if done improperly. Refer to “Jump Start-
ing” in “What To Do In Emergencies” for further
information.
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while cranking the engine. This should clear any
excess fuel, in case the engine is flooded.
250 STARTING AND OPERATING

NOTE:
•If the vehicle is started in extremely cold temperatures,
the transmission may not shift into Overdrive and will
automatically select the most desirable gear for opera-
tion at this temperature. Normal operation will re-
sume when the transmission fluid temperature has
risen to a suitable level. Refer to “Torque Converter
Clutch” in this section.
•If the transmission temperature gets extremely hot, the
transmission will automatically select the most desir-
able gear for operation at this temperature. If the
transmission temperature becomes hot enough, the
“Transmission Temperature Warning Light” may illu-
minate and the transmission may downshift out of
Overdrive until the transmission cools down. After
cool down, the transmission will resume normal
operation.The transmission will downshift from Overdrive to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).
When to Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL mode, top gear is disabled and
some shift patterns are modified. On vehicles with five-
speed transmissions, shifts into Overdrive (fourth gear)
are allowed during steady cruise (for improved fuel
economy), and automatic closed-throttle downshifts to
third gear (for improved braking) will occur during
steady braking.
