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
The cabin heating coolant is cooled
using a separate coolant loop.
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 Schedule0311.
The coolant reservoirs are in the
underhood compartment. See
Underhood Compartment Overview
0 253.
1. Cabin Heating Coolant
Reservoir
2. High Voltage Battery Coolant Reservoir
3. SPIM, APM, and Charger Module Coolant Reservoir
1. Park on a level surface and turn vehicle off.
2. After the system has completely cooled, check that
the coolant level is at the
COLD fill mark on the reservoir.
3. If coolant level is not visible or needs to be adjusted within the
reservoirs, contact your dealer.
Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall
below freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Underhood
Compartment Overview 0253 for
reservoir location.
Caution
. Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
. Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
