Charging System Light
On some vehicles the charging
system light comes on briefly when
the ignition is turned on, but the
engine is not running, as a check to
show the light is working. It should
go out when the engine is started.
For vehicles with a reconfigurable
cluster,this light may not come on
when the ignition is turned on.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer.Driving while this light is on
could drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a
message.
See Battery Voltageand Charging
Messages on page 5-36.
If a short distance mustbe driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
MalfunctionIndicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, 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 Ignition Positions on
page 9-15.
If the malfunction indicator lamp
comes on while the engine is
running, this indicates that there is
an OBD II 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 service technician in
correctly diagnosing any
malfunction.
