Vehicle Care 10-9Consistency of Readings Always check the fluid level at least
twice using the procedure described
previously. Consistency (repeatable
readings) is important to maintaining
proper fluid level. If readings are still
inconsistent, contact your dealer.

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.

{ WARNINGUsing an open flame near a
battery can cause battery gas to
explode. People have been hurt
doing this, and some have been
blinded. Use a flashlight if you
need more light.
Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a battery
has filler caps, be sure the right
amount of fluid is there. If it is low,
add water to take care of that
first. If you do not, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately. { WARNINGFans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.
6. Check that the jumper cables do
not have loose or missing
insulation. If they do, you could
get a shock. The vehicles could
be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) goes to
positive (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative ( − ) will go to a
heavy, unpainted metal engine
part or a solid engine ground.
Do not connect positive (+) to
negative ( − ) or you will get a
short that would damage the
battery and maybe other parts
too. Do not connect the
negative ( − ) cable to the negative ( − ) terminal on the dead
battery because this can cause
sparks.
7. Connect the red positive (+)
cable to the positive (+) terminal
of the vehicle with the dead
battery. Use a remote
positive (+) if the vehicle
has one.
8. Do not let the other end touch
metal. Connect it to the
positive (+) terminal of the good
battery. Use a remote
positive (+) if the vehicle
has one.
9. Now connect the black
negative ( − ) cable to the
negative ( − ) terminal of the good
battery. Use a remote
negative ( − ) if the vehicle
has one.
Do not let the other end touch
anything until the next step. The
other end of the negative ( − )
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part or
