Instruments and Controls
Charging System Light
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.
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 Voltage and Charging
Messages on page 5-39
.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator 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 9-20
.
If the malfunction indicator lamp
comes on while the engine is
running, this indicates that the
OBD II system has detected a
problem and diagnosis and service
might be required.
