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.

•Electronic Throttle Control (ETC) Light
This light informs you of a problem with
the Electronic Throttle Control (ETC) sys-
tem. The light will come on when the
ignition is first turned ON 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.
If a problem is detected, the light will come on while
the engine is running. Cycle the ignition key when
the vehicle has completely stopped and the shift lever
is placed in the PARK position. The light should turn
off.
If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an
authorized dealer for service as soon as possible. If
the light is flashing when the engine is running,
immediate service is required. You may experience reduced performance, an elevated/rough idle or en-
gine stall and your vehicle may require towing.
•
Engine Temperature Warning Light
This light warns of an overheated engine
condition. As temperatures rise and the gauge
approaches H,this indicator will illuminate
and a single chime will sound after reaching a set
threshold. Further overheating will cause the tem-
perature gauge to pass H,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 vehicle. 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 further
information.

formation. Tighten the fuel filler cap properly and press

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing. Normally, the OBD II system will be ready. The OBD II
system may
notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which
you can use prior to going to the test station. To check if
your vehicle’s OBD II system is ready, you must do the
following:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the MIL symbol come on as part
of a normal bulb check.

NOTE:
Lens fogging can occur under certain atmo-
spheric conditions. This will usually clear as atmospheric
conditions change to allow the condensation to change
back into a vapor. Turning the lamps on will usually
accelerate the clearing process.
