Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
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 when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
5. Low Fuel Light
When the fuel level reaches approximately 2.0 gal
(7.8 L), this light will turn on and remain on until
fuel is added.
6. Speedometer
The Speedometer shows the vehicle speed in miles per
hour (MPH) and kilometers per hour (km/h).
7. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
8. Turn Signal Indicators
The arrow will flash with the exterior turn
signal when the turn signal lever is operated. If
the vehicle is driven more than 1 mile (1.6 km)
with either turn signal on, a continuous chime
will sound to alert you to turn the signals off.

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
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
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size

NOTE:If the vehicle is equipped with the optional
Electronic Vehicle Information Center (EVIC) in the in-
strument cluster, warnings, such as “Door Ajar” and
“Gate Ajar,” will be displayed in the EVIC display. For
additional information, refer to “Electronic Vehicle Infor-
mation Center — If Equipped.”
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 push 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 tire pressure is low, the odometer display will
toggle between LoW and tirE for three cycles.
CHANgE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will
display on the instrument cluster odometer display for
approximately 12 seconds after a single chime has
sounded to indicate the next scheduled oil change inter-
val. 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

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 position.Do not
start the engine.
2. Fully push the accelerator pedal, slowly, three times
within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.

WARNING!(Continued)
•Unequal tire pressures from one side of the vehicle
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.
Both under-inflation and over-inflation affect the stability
of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
•Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
•Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnor-
mal wear patterns and reduced tread life, resulting in the
need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side B-Pillar or rear edge of the driver’s side
door.
