pointer in the red area. Engine damage will occur.
16. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is a part of
an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission con-
trol 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 referenced
above, can reach higher temperatures 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 result
in death or serious injury to the driver, occupants or
others.
17. Coolant Temperature Warning Light
This light warns of an overheated engine condi-
tion. 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 vehicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service.

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your

Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
22. Odometer / Trip Odometer / ECO (Fuel Saver Indi-
cator) Button
Press this button to change the display from odometer to
either of the two trip odometer settings or the “ECO”
display. Trip A or Trip B will appear when in the trip
odometer mode. Press and hold the button for two
seconds to reset the trip odometer to 0 miles or kilome-
ters. The odometer must be in trip mode to reset.

24. Gear Shift Indicator
This indicator will illuminate when a manual
shift is needed either up or down.
25. Odometer / Trip Odometer Display Area
The odometer display shows the total distance the ve-
hicle has been driven. The trip odometer shows indi-
vidual trip mileage. Refer to “Odometer / Trip Odometer
/ ECO (Fuel Saver Indicator) Button” for additional
information.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.

31. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is run-
ning, the light will either stay on or flash depending on
the nature of the problem. Cycle the ignition key when
the vehicle is safely and completely stopped and the shift
lever is placed in the PARK position. The light should
turn off. If the light remains on with the engine running,
your vehicle will usually be drivable; however, see an
authorized dealer for service as soon as possible.
If the light continues to flash when the engine is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is first turned to ON/RUN
and remain on briefly as a bulb check. If the light does not
come on during starting, have the system checked by an
authorized dealer.
32. Electronic Stability Control (ESC) OFF Indicator

play / Compass Mini-Trip Computer Display — If
Equipped
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages. For further information, refer to “Electronic
Vehicle Information Center”.
When the appropriate conditions exist, this display
shows the Mini-Trip Computer messages. Refer to “Mini-
Trip Computer” for further information.

Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will
remain in second gear regardless of which forward gear
is selected. PARK, REVERSE, and NEUTRAL will con-
tinue to operate. The Malfunction Indicator Light (MIL)
may be illuminated. Limp Home Mode allows the vehicle
to be driven to an authorized dealer for service without
damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized
dealer service is required.
438 STARTING AND OPERATING

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16” (2 mm). When the tread is worn to the tread
wear indicators, the tire should be replaced. Refer to
“Replacement Tires” in this section for further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
•Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
•Distance driven
•Performance tires, tires with a speed rating of V or
higher, and summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
