Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the LED is not lit during starting, have it
checked. If the light stays on, flickers, or comes on while
driving, have the system checked by an authorized
dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check the wheel nuts for tightness. Check the
tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, engine coolant, oil or other fluid leaks. Also, if
gasoline fumes are detected or fuel, power steering fluid,
transmission fluid or brake fluid leaks are suspected, the
cause should be located and corrected immediately.

4. Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on.
Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine.
The engine oil level must be checked under the hood.

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 tomaintain 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
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more

Distance To Empty (DTE)
Shows the estimated distance that can be traveled 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 vehicle
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 (48.3 km)
estimated driving distance, the DTE display will change
to a text display ofLOW FUEL. This display will
continue until the vehicle runs out of fuel. Adding a
significant amount of fuel to the vehicle will turn off the
LOW FUELtext and a new DTE value will be dis-
played, based on the current values in the DTE calcula-
tion and the current fuel tank level.
Elapsed Time
Shows the total elapsed time of travel since the last reset
when the ignition switch is in the ACC position. Elapsed
time will increment when the ignition switch is in the ON
or START position.

WARNING! (Continued)
•Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
•Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side “B” Pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
310 STARTING AND OPERATING

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring 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 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.
•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 gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
light.

FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high-quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended. The use of premium gaso-
line will provide no benefit over high-quality regular
gasolines and, in some circumstances may result in
poorer performance.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing service for the vehicle.
