Plug-in hybrid system
■Effects of outside temperature
When the charging mode is set to
“Departure”, charging schedule may
be ignored due to the outside tem-
perature and charging may start.
■“Battery Heater” ( P.115) /
“Battery Cooler” ( P.116)
When charging is c arried out using
the charging schedule, the hybrid
battery (traction battery) heating or
cooling function may operate
according to the te mperature of the
hybrid battery (traction battery).
●When the charging mode is set to
“Start”, the function starts at the
set charging start time.
●“Battery Heater”: When the
charging mode is set to “Depar-
ture”, the function starts automati-
cally to complete heating by the
desired departure time.
●“Battery Cooler”: When the
charging mode is set to “Depar-
ture”, cooling starts approximately
30 minutes before the charging
start time. However, if there is no
time to finish charging by the
charging schedule, the hybrid bat-
tery (traction battery) cooling time
may be shortened and “Battery
Cooler” may not operate.
When operating charging

■The information display at
low temperatures
Allow the interior of the vehicle to
warm up before u sing the liquid
crystal informat ion display. At
extremely low temperatures, the
display monitor may respond
slowly, and display changes may
be delayed.
For example, there is a lag
between the driver’s shifting and
the new shift range appearing on
the display. This lag could cause
the driver to downshift again,
causing rapid and excessive
engine braking and possibly an
accident resulting in death or
injury.
NOTICE
■To prevent damage to the
engine and its components
The engine may be overheating if
“Engine Coolant Temp High Stop
in a Safe Place See Owner’s
Manual” is shown on the multi-
information displa y. In this case,
immediately stop the vehicle in a
safe place, and c heck the engine
after it has cooled completely.

Driving
WARNING
●Do not attach adhesive discs to
the windshield or windows. Do
not place containers such as air
fresheners on the instrument
panel or dashboard. Adhesive
discs or containers may act as
lenses, causing a fire in the
vehicle.
●Do not leave a door or window
open if the curved glass is
coated with a metallized film
such as a silver-colored one.
Reflected sunlight may cause
the glass to act as a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift lever to P, stop the
hybrid system and lock the vehi-
cle.
Do not leave the vehicle unat-
tended while the “READY” indi-
cator is illuminated.
If the vehicle is parked with the
shift lever in P but the parking
brake is not set, the vehicle may
start to move, possibly leading
to an accident.
●Do not touch the exhaust pipes
while the “READY” indicator is
illuminated or immediately after
turning the hybrid system off.
Doing so may cause burns.
■When taking a nap in the
vehicle
Always turn the hyb rid system off.
Otherwise, if you accidentally
move the shift lever or depress
the accelerator p edal, this could
cause an accident or fire due to
hybrid system ove rheating. Addi-
tionally, if the vehicle is parked in
a poorly ventilated area, exhaust
gases may collect and enter the
vehicle, leading to death or a seri-
ous health hazard.
■When braking
●When the brakes are wet, drive
more cautiously.
Braking distance increases
when the brakes are wet, and
this may cause one side of the
vehicle to brake d ifferently than
the other side. A lso, the parking
brake may not securely hold the
vehicle.
●If the electronically controlled
brake system does not operate,
do not follow other vehicles
closely and avoid hills or sharp
turns that require braking.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing distance will increase. Have
your brakes fixed immediately.
●The brake system consists of 2
or more individual hydraulic sys-
tems; if one of the systems fails,
the other will still operate. In this
case, the brake pedal should be
depressed more firmly than
usual and the braking distance
will increase. Have your brakes
fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels exces-
sively when any of the tires is up
in the air, or the vehicle is stuck in
sand, mud, etc. This may damage
the driveline components or pro-
pel the vehicle forward or back-
ward, causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the hybrid system out-
put.

2765-1. Before driving
vehicle control. This is espe-
cially true on wet or slippery
surfaces.
 Avoid jerky starts or sudden
acceleration.
 Avoid jerky steering and
sharp turns, and slow down
before making turn.
 Note that when making a turn,
the trailer wheels will be
closer than the vehicle wheels
to the inside of the turn. Com-
pensate by making a wider
than normal turning radius.
 Slow down before making a
turn, in cross winds, on wet or
slippery surfaces, etc.
Increasing vehicle speed can
destabilize the trailer.
Take care when passing other
vehicles. Passing requires
considerable distance. After
passing a vehicle, do not for-
get the length of your trailer,
and be sure you have plenty
of room before changing
lanes.
 To maintain engine braking
efficiency, when using engine
braking, do not use the trans-
mission in D.
 Instability happens more fre-
quently when descending
steep or long downhill grades.
Before descending, slow
down and downshift. Do not
make sudden downshifts
while descending steep or long downhill grades.
 Avoid holding the brake pedal
down too long or applying the
brakes too frequently. This
could cause the brakes to
overheat and result in
reduced braking efficiency.
 Due to the added load of the
trailer, your vehicle’s hybrid
system may overheat on hot
days (at temperatures over
85°F [30°C]) when driving up
a long or steep grade. If the
high coolant temperature
warning light indicates over-
heating, immediately turn off
the air conditioning (if in use),
pull your vehicle off the road
and stop in a safe spot.
( P.544)
 Always place wheel blocks
under both the vehicle’s and
the trailer’s wheels when
parking. Apply the parking
brake firmly, and put the
transmission in P. Avoid park-
ing on a slope, but if unavoid-
able, do so only after
performing the following:
1 Apply the brakes and keep
them applied.
2 Have someone place wheel
blocks under both the vehi-
cle’s and trailer’s wheels.
3 When the wheel blocks are in
place, release the brakes
slowly until the blocks absorb
the load.

2805-2. Driving procedures
display, read the message and fol-
low the instructions.
■When the ambient temperature
is low, such as during winter
driving conditions
●When starting the hybrid system,
the flashing time of the “READY”
indicator may be long. Leave the
vehicle as it is until the “READY”
indicator is steady on, as steady
means the vehicle is able to move.
●When the hybrid battery (traction
battery) is extremely cold (below
approximately -22°F [-30°C])
under the influence of the outside
temperature, it may not be possi-
ble to start the hybrid system. In
this case, try to start the hybrid
system again after the tempera-
ture of the hybrid battery
increases due to the outside tem-
perature increase etc.

released, “Push power switch while turning the steering wheel in
either direction” will be displayed
on the multi-information display.
Check that the shift lever is set in
P. Press the power switch shortly
and firmly while turning the steer-
ing wheel left and right.
●To prevent the steering lock motor
from overheating
, the motor may
be suspended if the hybrid system
is turned on and off repeatedly in
a short period of ti me. In this case,
refrain from operating the power
switch. After about 10 seconds,
the steering lo ck motor will
resume functioning.
