Charging System Light

This light comes on briefly when the
ignition key is turned to START, but
the engine is not running, as a
check to show it is working.
If it does not, have the vehicle
serviced by your dealer.
The light should go out once the
engine starts. If it stays on,
or comes on while driving, there
could be a problem with the
charging system. This light could
indicate that there are problems with
a alternator drive belt, or that there
is an electrical problem. Have it
checked immediately. If the vehicle
must be driven a short distance with
the light on, turn off accessories,
such as the radio and air
conditioner.
Malfunction
Indicator Lamp
A computer system called EOBD
(European On-Board Diagnostics)
monitors the operation of the
vehicle to ensure emissions are at
acceptable levels, to produce a
cleaner environment. This light
comes on when the vehicle is
placed in ON/RUN for key access or
Service Only Mode for keyless
access, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
See Ignition Positions (Key Access)
on page 8‑14 or Ignition Positions
(Keyless Access) on page 8‑16 for
more information.
This light should come on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
If the malfunction indicator lamp
comes on and stays on while the
engine is running, this indicates that
there is an EOBD problem and
service is 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 assists
the dealer technician in correctly
diagnosing any malfunction.
