required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing.
•Engine Temperature Warning LightThis light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information.
•Transmission Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.

WARNING!
If the Transmission Temperature Warning Light is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.
Engine Oil Change Indicator System
Oil Change Due
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Due” message will
flash in the EVIC display for approximately 10 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 or cycle the ignition to the ON/RUN position if
equipped with Keyless Enter-N-Go. To turn off the
message temporarily, press and release the MENU but-
ton. To reset the oil change indicator system (after
performing the scheduled maintenance) refer to the fol-
lowing procedure.
Vehicles Equipped With Keyless Enter-N-Go
1. Without pressing the brake pedal, push the ENGINE
START/STOP button and cycle the ignition to the ON/
RUN position (Do not start the engine.)
2. Fully depress the accelerator pedal, slowly, three times
within 10 seconds.
3. Without pressing the brake pedal, push the ENGINE
START/STOP button once to return the ignition to the
OFF/LOCK position.

Vehicles Not Equipped With Keyless Enter-N-Go
1. Turn the ignition switch to the ON/RUN position (Do
not start the engine.)
2. Fully depress 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.
Fuel Economy
Press and release the UP or DOWN button until “Fuel
Economy” displays highlighted in the EVIC and press
the SELECT button. Press and release the UP/DOWN
buttons until one of the following Fuel Economy func-
tions displays in the EVIC:
•Average Fuel Economy/Fuel Saver Mode
•Distance To Empty (DTE)
•Miles Per Gallon (MPG)
Press the UP/DOWN buttons to cycle through all the
Trip Computer functions.
The Trip Functions mode displays the following informa-
tion:
Average Fuel Economy / Fuel Saver Mode — If
Equipped
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 average reading before the
reset.
The FUEL SAVER MODE message will display above the
average fuel economy in the EVIC display. This message
will appear whenever the Multi-Displacement System

UNDERSTANDING YOUR INSTRUMENT PANEL 311

(MDS) (if equipped) allows the engine to operate on four
cylinders, or if you are driving in a fuel efficient manner.
This feature allows you to monitor when you are driving
in a fuel efficient manner, and it can be used to modify
driving habits in order to increase fuel economy.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. DTE cannot be reset through the SELECT
button.
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 “LOW FUEL” message. 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” message and a new DTE value will display.

•Tire Pressure Monitor System (shows the current pres-
sure of all four road tires). For additional information,
refer to “Tire Pressure Monitor System” in “Starting
And Operating”.NOTE:
•Tires heat up during normal driving conditions. Heat
will cause the tire pressure to increase from 2 to 6 psi
(14 to 41 kPa) during normal driving conditions. Refer
to “Tires-General Information/Tire Inflation Pres-
sures” in “Starting And Operating” for additional
information.
•Your system can be set to display pressure units in PSI,
kPa, or BAR.

Turn Menu OFF
Select from Main Menu using the DOWN button. Press-
ing the SELECT button blanks the menu display. Pressing
any one of the four steering wheel buttons brings the
menu back.
Keyless Enter-N-Go Display — If Equipped
When the ENGINE START/STOP button is pressed to
change ignition switch positions, the Keyless Enter-N-Go
icon momentarily appears in the lower right corner of the
EVIC display showing the new ignition switch position.
Refer to “Keyless Enter-N-Go” in “Starting And Operat-
ing” for more information.
NOTE:Under certain conditions, the display may be
superseded by another display of higher priority. But
when the ignition switch position is changed, the display
always re-appears.
Compass / Temperature Display
The compass readings indicate the direction the vehicle is
facing. The EVIC will display one of eight compass
readings and the outside temperature.
NOTE: The system will display the last known outside
temperature when starting the vehicle and may need to
be driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect the
displayed temperature; therefore, temperature readings
are not updated when the vehicle is not moving.
Automatic Compass Calibration
This compass is self-calibrating, which eliminates the
need to manually reset the compass. When the vehicle is
new, the compass may appear erratic and the EVIC will
display CAL until the compass is calibrated. You may
also calibrate the compass by completing one or more
360–degree turns (in an area free from large metal or
4
UNDERSTANDING YOUR INSTRUMENT PANEL 317

metallic objects) until the CAL indicator displayed in the
EVIC turns off. The compass will now function normally.
NOTE:A good calibration requires a level surface and
an environment free from large metallic objects such as
buildings, bridges, underground cables, railroad tracks,
etc.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences, and provide the most accurate compass
heading. For the most accurate compass performance, the
compass must be set using the following steps.
NOTE: Keep magnetic materials away from the top of
the instrument panel, such as iPod’s, Mobile Phones,
Laptops and Radar Detectors. This is where the compass module is located, and it can cause interference with the
compass sensor, and it may give false readings.
1. Turn the ignition switch ON.
2. Press the UP or DOWN button until the Setup
(Customer-Programmable Features) menu is reached,
then press the SELECT button.
