Vehicle Care 10-15
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the vehicle if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans
should be running. If it is not, the
vehicle needs service. Turn off the
vehicle.
Cooling System (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 in the
battery, heats the coolant until the
correct temperature is reached.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled with
a 50/50 mixture of DEX-COOL
®
engine coolant and deionized water.
If using this mixture, nothing else
needs to be added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule on
page 11-2.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery coolant
reservoir is located in the engine
compartment. See
Engine
Compartment Overview on
page 10-8.
Check to see if coolant is visible in
the high voltage battery coolant
reservoir. If coolant is visible but the

coolant level is below the cold fill
line, there could be a leak in the
cooling system.
The high voltage battery coolant
should only be serviced by a
qualified technician.
Cooling System (Power
Electronics and Charger
Modules)
The power electronics and charger
modules are cooled using the same
coolant loop.
The power electronics and charger
modules in the vehicle are kept
below a maximum temperature.
If the temperature rises above this
temperature, the electric cooling
fans will turn on and cool the
coolant until the correct temperature
is reached.
What to Use
The power electronics and charger
modules coolant reservoir in the
vehicle is filled with a 50/50 mixtureof DEX-COOL engine coolant and
deionized water. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule on
page 11-2.

13. Set all four tires to therecommended air pressure
level as indicated on the Tire
and Loading Information label.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). The first
rotation is the most important.
SeeMaintenance Schedule on
page 11-2.
Tires are rotated to achieve a
more uniform wear for all tires.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. See When It Is Time
for New Tires on page 10-53
and Wheel Replacement on
page 10-58.
Use this rotation pattern when
rotating the tires.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure on page 10-46
and Vehicle Load Limits on
page 9-12.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
