as a system check. Then, after
several more seconds, the status
indicator will light either ON or OFF,
or the on or off symbol, to let you
know the status of the front
outboard passenger frontal airbag
and knee airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag
and knee airbag are allowed to
inflate.
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag
and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5-16 for more
information, including important
safety information.
Charging System Light
(12-Volt Battery)
The charging system light comes on
briefly when the vehicle is in ON/
RUN, as a check to show the light is
working. If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the 12‐volt battery.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the vehicle. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
Service Only Mode, as a check to
show it is working. If it does not,
have the vehicle serviced by your
dealer. See
Power Button on
page 9-16 for more information.

5-18 Instruments and Controls
If the malfunction indicator lamp
comes on, while the engine is in
ON/RUN, this indicates that the
OBD II system has detected a
problem and diagnosis and service
might be required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the dealer technician in
correctly diagnosing any
malfunction.
{Caution
If the vehicle is continually driven
with this light on, the emission
controls might not work as well,(Continued)
Caution (Continued)
the vehicle fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.
{Caution
Modifications made to the engine,
electric drive unit, exhaust, intake,
or fuel system of the vehicle or
the replacement of the original
tires with other than those of the
same Tire Performance Criteria
(TPC) can affect the vehicle
emission controls and can cause
this light to come on.
Modifications to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure(Continued)

to pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications on
page 10-2.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
If the light continues to flash, find a
safe place to stop and park the
vehicle. Turn the vehicle off and
wait at least 10 seconds before
driving the vehicle again. If the light

begins to flash again, follow the
previous steps and see your dealer
for service as soon as possible.
Light On Steady:An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emission control system
malfunction:
.Check that the fuel cap is fully
installed. The diagnostic system
can determine if the fuel cap has
been left off or improperly
installed. A loose or missing fuel
cap allows fuel to evaporate into
the atmosphere. A few driving
trips with the cap properly
installed should turn the light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up or
misfiring. These conditions might
go away once the engine is
warmed up.
If one or more of these
conditions occurs, change the
fuel brand used. It may require
at least one full tank of the
proper fuel to turn the light off.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on while the vehicle is in ON/
RUN, or if the vehicle is placed
in Service Only Mode and the
malfunction indicator lamp does
not come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.

.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed by the
system. If this were to occur, the
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or
run down.
The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of driving. If this
has been done and the vehicle
still does not pass the inspection
for lack of OBD II system
readiness, your dealer can
prepare the vehicle for
inspection.Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
