276 DRIVING AND OPERATING
The vehicle has a Charging Status
Indicator (CSI) at the center of the
instrument panel near the windshield.
When the vehicle is plugged in and
the vehicle power is off, the CSI
indicates the following:
.Short Flashing Green –Vehicle is
plugged in. Battery is not fully
charged. Flash rate increases from
one to four flashes as battery
charges.
. Long Flashing Green –Vehicle is
plugged in. Battery is not fully
charged. Battery charging is
delayed.
. Solid Green –Vehicle is plugged
in. Battery is fully charged.
. Solid Yellow –Vehicle is plugged
in. It is normal for the CSI to turn
yellow for a few seconds after
plugging in a compatible charge
cord. The solid yellow may be
extended depending on the vehicle
and if there is a total utility
interruption via OnStar. See Utility
Interruption of Charging (PLUG-IN
Only) 0284. This may also indicate
that the charging system has
detected a fault and will not charge the battery. See
“Charge
Cord Status Indicators ”in Charge
Cord (PLUG-IN Only) 0279.
If the vehicle is plugged in and vehicle
power is on, the CSI will flash or will
be solid green, depending on the
charge level. This also happens during
a remote start if the vehicle is
plugged in.
If the vehicle is plugged in and the
CSI is off, a total utility interruption
using OnStar or a charging fault has
been detected. See Utility Interruption
of Charging (PLUG-IN Only) 0284 or
“Charge Cord Status Indicators ”in
Charge Cord (PLUG-IN Only) 0279.
A message displays if the vehicle is
not able to charge.
Following is the vehicle feedback
when the charge cord is plugged in.

Customer Satisfaction
Procedure
Your satisfaction and goodwill are
important to your dealer and to
Cadillac. Normally, any concerns with
the sales transaction or the operation
of the vehicle will be resolved by your
dealer's sales or service departments.
Sometimes, however, despite the best
intentions of all concerned,
misunderstandings can occur. If your
concern has not been resolved to your
satisfaction, the following steps
should be taken:
STEP ONE : Discuss your concern
with a member of dealership
management. Normally, concerns can
be quickly resolved at that level. If the
matter has already been reviewed with
the sales, service or parts manager,
contact the owner of your dealership
or the general manager.
STEP TWO : If after contacting a
member of dealership management, it
appears your concern cannot be
resolved by your dealership without
