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 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.
‐ One Flash: 0–25% Charge
‐ Two Flashes: 26–50% Charge
‐ Three Flashes: 51–75% Charge
‐ Four Flashes: 76–100% Charge
.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 CSI may stay
solid yellow longer depending on the
vehicle and if there is a total utility
interruption. See Utility Interruption of
Charging 0210. This may also indicate
that the charging system has detected a
fault and will not charge the battery. See
“Charge Cord Status Indicators” under
Charge Cord 0204.
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. If the vehicle is plugged in and the CSI is
off, a total utility interruption or a charging
fault has been detected. See

Cooling System
It is not necessary to regularly check coolant
unless a leak is suspected or an unusual
noise is heard. A coolant loss could indicate
a problem. Have it inspected and repaired
by your dealer.
The following explains the cooling systems
and how to check coolant levels.
.High Voltage Battery
.Single Power Inverter Module (SPIM),
Accessory Power Module (APM), and
Charger Module
.Cabin Heating
High Voltage Battery
During vehicle operation and also during
charging, the high voltage battery cells in
the vehicle are kept within a normal
operating temperature range. If the
temperature rises above this temperature,
the battery cooling system turns on the air
conditioning compressor and cools the
coolant until the correct temperature is
reached. If the temperature falls below this
temperature, a high voltage heater, located
outside the battery on a cradle, heats the
coolant until the correct temperature is
reached.
Single Power Inverter Module (SPIM),
Accessory Power Module (APM), and
Charger Module
The SPIM, APM, and charger module are
cooled using a separate coolant loop. These
modules are kept below a maximum
temperature. If the temperature rises above
this temperature, the electric cooling fan will
turn on to cool the coolant.
Cabin Heating
Cabin heating is maintained by coolant
heated by the Coolant Heater Control
Module (CHCM), separate from the power
electronics and battery coolant loops. This
module heats the coolant based on
temperature inputs from the cabin climate
control systems.
Hybrid Cooling System Pressure Caps
The hybrid cooling system reservoirs have
tamper resistant pressure caps. The coolant
should only be serviced by a qualified
technician.
Checking Coolant
The coolant needs to be replaced at the
appropriate interval. See Maintenance
Schedule 0271.
The coolant reservoirs are in the underhood
compartment. See Underhood Compartment
Overview 0216.
