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 0113 for more information,
including important safety
information.
Charging System Light
(12-Volt Battery)
The charging system light comes on
briefly when the vehicle is started,
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 (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the vehicle is in
Service Mode. See Power Button
0 168.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.

Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
electric drive unit, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’s ability to pass(Continued)
Caution (Continued)
an Emissions Inspection/
Maintenance test. See
Accessories and Modifications
0237.
If the light is flashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If the light continues to flash, find a
safe place to park. Turn the vehicle
off and wait at least 10 seconds
before restarting the engine. If the
light is still flashing, follow the
previous guidelines and see your
dealer for service as soon as
possible. If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. A loose or missing fuel cap may
cause the light to come on. See
Filling the Tank 0230. A few
driving trips with the cap
properly installed may turn the
light off.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed
up. If this occurs, change the
fuel brand. It may require at
least one full tank of the proper
fuel to turn the light off. See
Recommended Fuel 0229.
If the light remains on, see your
dealer.

116 Instruments and Controls
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the
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. Connecting devices that are
not used to perform an Emissions
Inspection/Maintenance test or to
service the vehicle may affect
vehicle operation. SeeAdd-On
Electrical Equipment 0233. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine
is running. .
The light does not come on
when the vehicle is in
Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.
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.

Programmable Charging
Important Information about
Portable Electric Vehicle Charging
. Charging an electric vehicle can
stress a building’ s electrical
system more than a typical
household appliance.
. Before plugging into any
electrical outlet, have a qualified
electrician inspect and verify the
electrical system (electrical
outlet, wiring, junctions, and
protection devices) for
heavy-duty service at a 12 amp
continuous load.
. Electrical outlets may wear out
with normal usage or may be
damaged over time, making
them unsuitable for electric
vehicle charging.
. Check the electrical outlet/plug
while charging and discontinue
use if the electrical outlet/plug is
hot, then have the electrical
outlet serviced by a qualified
electrician.
