1. High Voltage BatteryCoolant Reservoir
2. Power Electronics Coolant Reservoir
Check to see if coolant is visible in
the power electronics coolant
reservoir (2). If coolant is visible but
the coolant level is below the cold
fill line on the side of the reservoir,
there could be a leak in the cooling
system.
The power electronics cooling
system supports the operation of
sensitive electronics. The power electronics cooling
system should only be serviced by a
qualified technician.
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. See
Roadside Assistance Program
0
345.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the vehicle,
and have the vehicle serviced.
Caution
Do not run the engine when there
is a leak in the hybrid cooling
system. This can cause a loss of
all coolant and can damage the
system and the vehicle. Have any
leaks fixed right away.
Washer Fluid
What to Use
When adding windshield washer
fluid to the vehicle, 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.
