This display shows the temperature
of the engine coolant in either
degrees Celsius (°C) or degrees
Fahrenheit (°F). Vehicle Messages Messages displayed on the DIC
indicate the status of the vehicle
or some action may be needed
to correct a condition. Multiple
messages may appear one after
another.
The messages that do not
require immediate action can be
acknowledged and cleared by

9-4 Driving and Operating
Engine Coolant Heater The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below − 18°C (0°F). Vehicles
with an engine heater should be
plugged in at least four hours before
starting. An internal thermostat in
the plug-end of the cord may exist
which will prevent engine coolant
heater operation at temperatures
above − 18°C (0°F). Using the Engine Coolant
Heater 1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
secured to a wiring harness
between the engine and the
Hybrid Auxiliary Underhood
Fuse Block with a clip. Carefully
remove the wire tie which
secures the electrical cord.
Do not cut the electrical cord.
3. Plug the cord into a normal,
grounded 110-volt AC outlet.
{ WARNINGPlugging the cord into an
ungrounded outlet could cause
an electrical shock. Also, the
wrong kind of extension cord
could overheat and cause a fire.
You could be seriously injured.
Plug the cord into a properly
grounded three-prong 110-volt
AC outlet. If the cord will not
reach, use a heavy-duty
three-prong extension cord
rated for at least 15 amps.

10-8 Vehicle Care
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.

Coolant Surge Tank
Pressure Cap
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
