Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow Telltale Light 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 en-
gine 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.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy
and driveability. 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 ref-
erenced above, can reach higher tempera-
tures 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 re-
sult in death or serious injury to the driver,
occupants or others.

Tire Pressure Monitoring Indicator Light
Yellow Telltale Light What It Means
Tire Pressure Monitoring Indicator Light
The warning light switches on and a message is displayed to indicate that the tire pressure is lower than the recom-
mended value and/or that slow pressure loss is occurring. In these cases, optimal tire duration and fuel consumption may
not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the indications corresponding to each
tire in sequence.
IMPORTANT:Do not continue driving with one
or more flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp braking
and steering. Repair immediately using the
dedicated tire repair kit and contact your autho-
rized dealership as soon as possible.
Each 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 pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible and inflate them to the proper pres-
sure. 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’sresponsibility 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 approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be

Anti-Lock Brake (ABS) Indicator Light
Yellow Telltale Light What It Means
Anti-Lock Brake (ABS) Indicator Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the ignition is placed in the ON/RUN po-
sition and may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, then the Anti-Lock portion of the brake system is not functioning and
service is required. However, the conventional brake system will continue to operate normally if the brake warning light is
not on.
If the ABS light is on, the brake system should be serviced as soon as possible to restore the benefits of Anti-Lock Brakes.
If the ABS light does not turn on when the ignition is placed in the ON/RUN position, have the light inspected by an autho-
rized dealer.

Oil Change Required
Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change Re-
quired” message will display in the EVIC display
for approximately five seconds after a single
chime has sounded to indicate the next sched-
uled oil change interval. The engine oil change
indicator system is duty-cycle based, whichmeans the engine oil change interval may fluc-
tuate dependent upon your personal driving

Average Fuel EconomyShows the average fuel economy since the last
reset (pushing and holding theRIGHTarrow
button as prompted in the EVIC display to
reset). When the fuel economy is reset, the
display will read “RESET” or show dashes for
two seconds. Then, the history information will
be erased, and the averaging will continue from
the last fuel reading before the reset.
Distance To Empty (DTE)Shows the estimated distance that can be trav-
elled with the fuel remaining in the tank. This
estimated distance is determined by a weighted
average of the instantaneous and average fuel
economy, according to the current fuel tank
level. This is not resettable.NOTE:
Significant changes in driving style or ve-
hicle loading will greatly affect the actual
drivable distance of the vehicle, regardless
of the DTE displayed value.
When the DTE value is less than 30 miles
(48 km) estimated driving distance, the DTE
display will change to a text display of"LOW
FUEL.” This display will continue until the ve-
hicle runs out of fuel. Adding a significant
amount of fuel to the vehicle will turn off the
"LOW FUEL"text and a new DTE value will be
displayed, based on the current values in the
DTE calculation and the current fuel tank level.

modes. The closer the setting is to a particular
symbol, the more air distribution you receive
from that mode.
•Panel
Air is directed through the outlets in the
instrument panel. These outlets can be
adjusted to direct airflow.
NOTE:
The center instrument panel outlets can be
aimed so that they are directed toward the
rear seat passengers for maximum airflow
to the rear.
•Bi-Level
Air is directed through the panel and
floor outlets.
NOTE:
For all settings, except full cold or full hot,
there is a difference in temperature between
the upper and lower outlets. The warmer air
flows to the floor outlets. This feature gives
improved comfort during sunny but cool
conditions.•Floor
Air is directed through the floor outlets
with a small amount flowing through
the defrost and side window demist
outlets.
•Mix
Air is directed through the floor, de-
frost, and side window demist outlets.
This setting works best in cold or
snowy conditions that require extra heat to the
windshield. This setting is good for maintaining
comfort while reducing moisture on the
windshield.
•Defrost
Air is directed through the windshield
and side window demist outlets. Use
this mode with maximum blower and
temperature settings for best windshield and
side window defrosting.
NOTE:
•The air conditioning compressor oper-
ates in Mix, Defrost, or a blend of these
modes, even if the Air Conditioning (A/C)button is not pushed. This dehumidifies
the air to help dry the windshield. To

button will put the system in recir-
culation mode. This can be used
when outside conditions such as
smoke, odors, dust, or high humid-
ity are present. Activating recirculation will
cause the LED in the control button to illumi-
nate.
NOTE:
•Continuous use of the Recirculation
mode may make the inside air stuffy and
window fogging may occur. Extended use
of this mode is not recommended.
