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 LightThis 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 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
Indicates vehicle speed.
7. Airbag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned ON. If the light is either not on during
starting, stays on, or turns on while driving,
then 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.
9. High Beam Indicator This indicator shows that the high beam head-
lights are on. Push the multifunction lever forward

20. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
NOTE:You must apply the brakes before shifting from
PARK.
21. Odometer/Trip Odometer Reset Button
Press this button to change the display from odometer to
either of the two trip odometer settings. Trip A or Trip B
will appear when in the trip odometer mode. Push in and
hold the button for two seconds to reset the trip odometer
to 0 miles (0 km). The odometer must be in Trip mode to
reset.
22. Tire Pressure Monitoring Telltale Light 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 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

To Reset The Display
Pressing and holding the EVIC button once will clear the
function currently being displayed. Reset will only occur
if a resettable function is currently being displayed. To
reset all resettable functions, press and release the EVIC
button a second time within three seconds of resetting the
currently displayed function. Reset ALL will be dis-
played during this three-second window.
Compass/Temperature/Audio
Press and release the EVIC button to display one of eight
compass headings to indicate the direction the vehicle is
facing, the outside temperature, and the current radio
station.
For additional information regarding the compass, refer
to Personal Settings (Customer-Programmable Features).
Average Fuel Economy
Shows the average fuel economy since the last 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 traveled with
the fuel remaining in the tank. This estimated distance is
206 UNDERSTANDING YOUR INSTRUMENT PANEL

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 km)
estimated driving distance, the DTE display will change
to a text display of LOW 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 FUEL text 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.
Tire Pressure Monitor (TPM)
Refer to “Starting And Operating”, “Tire Pressure Moni-
toring System (TPMS)” for system operation.
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.
Personal Settings (Customer-Programmable
Features)
This allows the driver to set and recall features when the
transmission is in PARK (automatic transmission) or the
vehicle is stopped (manual transmission).
Press and release the EVIC button until “Personal Set-
tings” is displayed in the EVIC.
Use the EVIC button to display one of the following
choices:
Language
When in this display you may select different languages
for all display nomenclature, including the trip functions.

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. Under-inflation also increases
tire rolling resistance and results in higher fuel
consumption.
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 left
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 under-inflated.

STARTING AND OPERATING 343

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.
