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.
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.
The cooling system allows the
vehicle to maintain the correct
working temperature.Checking Coolant
The coolant needs to be
replaced at the appropriate
interval. See Maintenance
Schedule
0376.
The coolant reservoir is in the
underhood compartment. See
Underhood Compartment
Overview 0312.
To access the coolant
reservoir under the hood, the
right side access cover needs
to be removed. 1. Park on a level surface and turn the vehicle off.
2. Open the hood. See Hood 0310.
3. The coolant reservoir is
under a cover and side
extension/shield in the
underhood compartment.
Unclip the right side of the
shield and remove the right
side access cover.

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
If the vehicle is equipped with
a washer fluid level indicator,
and the washer fluid reservoir
is low, a message displays on
the Driver Information Center
(DIC). See Driver Information
Center (DIC) 0132 for more
information.
Open the cap with the washer
symbol on it. Add washer fluid
until the tank is full. See
Underhood Compartment
Overview 0312 for reservoir
location.
