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.

9-6 Driving and Operating Leaving the Vehicle with the
Engine Running
{ WARNINGIt can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set.
If you have four-wheel drive and
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 gear — not in
N (Neutral).
(Continued) WARNING (Continued) And, if you leave the vehicle
with the engine running, it could
overheat and even catch fire. You
or others could be injured. Do not
leave the vehicle with the engine
running unless you have to.
If you have to leave the vehicle with
the engine running, be sure your
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you move the shift
lever into P (Park), hold the regular
brake pedal down. Then, see if you
can move the shift lever away from
P (Park) without first pulling it toward
you. If you can, it means that the
shift lever was not fully locked into
P (Park). Torque Lock If parking on a hill and the
transmission not shifted into
P (Park) properly, the weight
of the vehicle may put too much
force on the parking pawl in the
transmission. You may find it
difficult to pull the shift lever out
of P (Park). This is called torque
lock. To prevent torque lock, set the
parking brake and then shift into
P (Park) properly before you leave
the driver seat. To find out how, see
Shifting Into Park on page 9 ‑ 5 .
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake.
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the parking pawl
in the transmission, then you will be
able to pull the shift lever out of
P (Park).

Automatic Transmission
Fluid When to Check and Change
Automatic Transmission Fluid It is usually not necessary to
check the transmission fluid level.
The only reason for fluid loss is a
transmission leak or overheating
the transmission. If a small leak is
suspected, then use the following checking procedures to check the
fluid level. However, if there is a
large leak, then it may be necessary
to have the vehicle towed to a
dealer and have it repaired before
driving the vehicle further.
Notice: Use of the incorrect
automatic transmission fluid
may damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11 ‑ 2 .
Change the fluid and filter at the
scheduled maintenance intervals.
See “ Scheduled Maintenance ” in
the owner manual. Be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants on page 11 ‑ 2 .

10-6 Vehicle Care How to Check Automatic
Transmission Fluid Notice: Too much or too
little fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if checking the
transmission fluid.
Before checking the fluid level,
prepare the vehicle as follows:
1. Start the engine and park the
vehicle on a level surface. Keep
the engine running.
2. Apply the parking brake and
place the shift lever in P (Park).
3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, move the
shift lever back to P (Park). 4. Allow the engine to idle
(500 – 800 RPM) for at least
one minute. Slowly release the
brake pedal.
5. Keep the engine running and
press the Trip/Fuel button or
trip odometer reset stem until
TRANS TEMP (Transmission
Temperature) displays on the
Driver Information Center (DIC).
6. Using the TRANS TEMP
reading, determine and perform
the appropriate check
procedure. If the TRANS TEMP
reading is not within the required
temperature ranges, allow the
vehicle to cool, or operate the
vehicle until the appropriate
transmission fluid temperature is
reached. Cold Check Procedure
Use this procedure only as a
reference to determine if the
transmission has enough fluid
to be operated safely until a hot
check procedure can be made.
The hot check procedure is the
most accurate method to check the
fluid level. Perform the hot check
procedure at the first opportunity.
Use this cold check procedure
to check fluid level when the
transmission temperature is
between 24°C and 34°C
(75°F and 93°F).
1. Locate the transmission dipstick
at the rear of the engine
compartment, on the passenger
side of the vehicle.
