In case the ignition switch does not change with the push of
a button, the key fob may have a low or fully depleted
battery. A low key fob battery can be verified by referring to
the instrument cluster, which will display directions to
follow.
NOTE:
A low key fob battery condition may be indicated by a
message in the instrument cluster display, or by the LED
light on the key fob. If the LED key fob light no longer illu-
minates from key fob button pushes, then the key fob battery
requires replacement.
In a situation where the battery is low or fully depleted, a
back up method can be used to operate the ignition switch.
Put the nose side of the key fob (side opposite of the emer-
gency key) against the START/STOP ignition button and
push to operate the ignition switch.

If your OBD II system is not ready, you should see an autho -
rized dealer or repair facility. If your vehicle was recently
serviced or had a battery failure or replacement, you may
need to do nothing more than drive your vehicle as you
normally would in order for your OBD II system to update.
A recheck with the above test routine may then indicate that
the system is now ready. Regardless of whether your vehicle's OBD II system is ready
or not, if the MIL is illuminated during normal vehicle oper
-
ation you should have your vehicle serviced before going to
the I/M station. The I/M station can fail your vehicle
because the MIL is on with the engine running.
