Engine Coolant
Temperature Gauge
United States
Canada
This gauge shows the engine
coolant temperature.
It also provides an indicator of how
hard the vehicle is working. During a
majority of the operation, the gauge
reads 100°C (210°F) or less. If a
load is being pulled or going up
hills, it is normal for the temperature
to fluctuate and go over the 113°C
(235°F) mark. However, if the gauge
reaches the 125°C (260°F) mark, it
indicates that the cooling system is
working beyond its capacity.
Charging System Light
This 12‐volt battery light comes on
briefly when the ignition is turned to
ON/RUN, but the engine is not
running, as a check to show it is
working.
It should go out once the engine
has been started. If it stays on,
or comes on while driving, there
could be a problem with the 12‐volt
charging system. Have the vehicle
serviced by your dealer. A 12‐volt
charging system Driver Information
Center (DIC) message may also
appear. See Driver Information
Center (DIC) on page 5‑11 for more
information. This light could indicate
that there are electrical problems.

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.
{WARNING
Plugging 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.
Shifting Into Park
{WARNING
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake firmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow. With four-wheel drive,
if the transfer case is in
N (Neutral), the vehicle will be
free to roll, even if the shift lever
is in P (Park). So, be sure the
transfer case is in a drive
