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. 4. Before starting the engine, be
sure to unplug and store the
cord as it was before to keep it
away from moving engine parts.
If you do not, it could be
damaged.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.

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 “ Engine Coolant ” and
“ Cooling System ” in the owner
manual for more information.

recommended inflation
pressure using the pressure
gauge (E). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure on page 10 ‑ 17 .
The pressure gauge (E) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate reading. The
compressor may be turned on/
off until the correct pressure is
reached. 12. Press the on/off button (D) to
turn the tire sealant and
compressor kit off.
