5. Safe operating level is within the
HOT cross hatch band on the
dipstick. If the fluid level is not
within the HOT band, and the
transmission temperature is
between 60°C and 75°C
(140°F and 167°F), add or
drain fluid as necessary to bring
the level into the HOT band.
If the fluid level is low, add only
enough fluid to bring the level
into the HOT band. It does not
take much fluid, generally less
than 0.5 Liter (1 Pint). Do not
overfill.
6. If the fluid level is in the
acceptable range, push the
dipstick back in all the way. Consistency 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

10-10 Vehicle Care How 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.
{ WARNING
Steam 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.
(Continued) WARNING (Continued) 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.
{ WARNING
You 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

{ 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 to the remote negative ( − )
terminal on the vehicle with the
dead battery.
10. Connect the other end of the
negative ( − ) cable to the
remote negative ( − ) terminal,
on the vehicle with the dead
battery.
11. Now start the vehicle with the
good battery and run the
engine for a while.
12. Try to start the vehicle that
had the dead battery. If it will
not start after a few tries, it
probably needs service.
Notice: If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct
order, making sure that the
cables do not touch each other or
other metal.
