See Engine Compartment Overview
on page 10 ‑ 4 for more information
on location. The Drive Motor/Generator Control
Module (DMCM) coolant surge tank
pressure cap must be fully installed
on the hybrid coolant surge tank.
Notice: If the pressure cap is not
tightly installed, coolant loss and
possible damage to the Drive
Motor/Generator Control
Module (DMCM) may occur. Be
sure the cap is properly and
tightly secured. Drive Motor/Generator
Control Module (DMCM)
Cooling System In addition to the regular cooling
system, the vehicle also has a
cooling system for the DMCM
system. This system is serviced
differently than the vehicle's main
cooling system. The DMCM cooling
system includes the DMCM coolant
surge tank, DMCM surge tank
pressure cap, DMCM cooling
pumps, hybrid cooling radiator and
the Drive Motor/Generator Control
Module (DMCM). The DMCM
cooling system uses a 50/50
pre-mixed DEX-COOL ®
coolant and
deionized water available at your
dealer. See “ Engine Coolant ” and
“ Cooling System ” in the owner
manual for more information.

Vehicle Care 10-11How to Add Coolant to the
DMCM Coolant Surge Tank
If no problem has been found yet,
check to see if coolant is visible in
the DMCM coolant surge tank.
If coolant is visible, add pre ‐ mixed
DEX-COOL coolant, available at
your dealer, at the DMCM coolant
surge tank, but be sure the DMCM
cooling system, including the DMCM
coolant surge tank pressure cap, is
cool before you do it. Use the
procedure following. { WARNINGSteam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the coolant surge tank pressure
cap — even a little — they can
come out at high speed. Never
turn the cap when the cooling
system, including the coolant
surge tank pressure cap, is hot.
Wait for the cooling system and
coolant surge tank pressure cap
to cool if you ever have to turn
the pressure cap.
Notice: Using coolant other than
a pre ‐ mixed DEX-COOL, available
at your dealer, may damage your
vehicle. Any repairs would not be
covered by your warranty. Always
use a pre ‐ mixed DEX-COOL
(silicate-free) coolant in your
vehicle. { WARNINGYou can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
If the DMCM coolant is empty , the
vehicle must be serviced by your
dealer and a special fill procedure
must be followed.
Notice: Attempting to fill the
DMCM cooling surge tank
yourself when the fluid level is
empty can damage your vehicle.
Your vehicle must be serviced.

1. Park the vehicle on a level
surface and turn the vehicle off.
Remove the DMCM coolant
surge tank pressure cap when
the DMCM cooling system,
including the DMCM coolant
surge tank pressure cap and
DMCM cooling hoses, are no
longer hot. Turn the DMCM
coolant surge tank pressure cap
slowly counterclockwise (left)
about one full turn. Wait
30 seconds. 2. Then keep turning the DMCM
coolant surge tank pressure cap
slowly, and remove it.
3. Add the pre ‐ mixed DEX ‐ COOL,
available at your dealer, to the
DMCM coolant surge tank until
the level reaches the FULL
COLD mark. 4. Turn the ignition to ON/RUN
without starting the engine. The
hybrid cooling pumps will run
and any trapped air will purge to
the surge tank.
5. Add the pre ‐ mixed DEX ‐ COOL,
available at your dealer, until the
coolant level is maintained at the
FULL COLD mark. This should
take no longer than two minutes
of hybrid cooling pump
operation.
If the level cannot be kept at the
FULL COLD level, the vehicle
may need service. See your
dealer.

6. Then replace the DMCM coolant
surge tank pressure cap. Be
sure the pressure cap is
hand-tight and fully seated.
Notice: Using tap water, cooling
system sealers or conditioners in
an attempt to stop coolant leaks
can damage the DMCM and
engine cooling systems. Never
use tap water, cooling system
sealers or conditioners in your
cooling system.
Power Steering Fluid The vehicle has electric power
steering and does not use power
steering fluid. Battery This vehicle has a standard 12 ‐ volt
battery and a high voltage hybrid
battery.
Refer to the replacement number on
the original battery label when a
new standard 12 ‐ volt battery is

Electrical System High Voltage Devices and
Wiring
{ WARNINGExposure to high voltage can
cause shock, burns, and even
death. The high voltage systems
in your vehicle can only be
serviced by technicians with
special training.
High voltage devices are
identified by labels. Do not
remove, open, take apart,
or modify these devices. High
voltage cable or wiring has
orange covering. Do not probe,
tamper with, cut, or modify high
voltage cable or wiring. Fuses and Circuit
Breakers The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses, circuit
breakers and fusible thermal links.
This greatly reduces the chance of
fires caused by electrical problems.
Be sure you replace a bad fuse with
a new one of the identical size and
rating.
If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the vehicle that you can
get along without, like the radio or
cigarette lighter, and use its fuse,
if it is the correct amperage.
Replace it as soon as you can.
The vehicle also has a special fuse
in the battery box for the 300-volt
batteries. If this fuse has failed and
needs to be replaced, the vehicle
will be disabled and you will need to have the vehicle repaired by your
dealer. Do not attempt to
self-service this fuse.

10-20 Vehicle Care TPMS Malfunction Light and
Message The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire warning light flashes for
about one minute and then stays on
for the remainder of the ignition
cycle. A DIC warning message is
also displayed. The low tire warning
light and DIC warning message
come on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause the
malfunction light and DIC message
to come on are: .
The TPMS sensor matching
process was started but not
completed or not completed
successfully after rotating the
vehicle's tires. The DIC message
and TPMS malfunction light
should go off once the TPMS
sensor matching process is
performed successfully. See
“ TPMS Sensor Matching
Process ” later in this section. .
One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer for
service. .
Replacement tires or wheels do
not match your vehicle's original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. See
“ Buying New Tires ” in the owner
manual. .
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction. If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer for
service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process Each TPMS sensor has a unique
identification code. Any time you
rotate your vehicle's tires or replace
one or more of the TPMS sensors,
the identification codes will need to
be matched to the new tire/wheel
position. The sensors are matched
to the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer for service.

If a Tire Goes Flat Your vehicle has a tire inflator kit.
There is no spare tire, no tire
changing equipment, and no place
to store a tire.
It is unusual for a tire to blow out
while you are driving, especially if
you maintain your tires properly.
If air goes out of a tire, it is much
more likely to leak out slowly. But,
if you should ever have a blow out,
here are a few tips about what to
expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blow out, particularly on a
curve, acts much like a skid and
may require the same correction
you would use in a skid. In any rear
blow out, remove your foot from the
accelerator pedal. Get the vehicle under control by steering the way
you want the vehicle to go. It may
be very bumpy and noisy, but you
can still steer. Gently brake to a
stop, well off the road, if possible.
{ WARNINGDriving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has
been driven on while severely
under-inflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely under-inflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible. If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place and stopping, well
off the road, if possible. Then
do this:
1. Turn on the hazard warning
flashers.
2. Park your vehicle. Set the
parking brake firmly and put the
shift lever in PARK (P).
3. Turn off the engine.
4. Inspect the flat tire.
If the tire has been separated from
the wheel or has damaged sidewalls
or large tears that allow rapid air
loss, call a tire repair facility. See
“ Roadside Assistance Program ” in
the owner manual.
If the flat tire is due to a slow leak
caused by a nail or other similar
road hazard, the tire inflator kit may
be used to repair the damaged tire
temporarily. The kit uses a liquid tire
sealant to seal small punctures in
the tread area of the tire.
