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 hybrid system off.
Otherwise, if you accidentally
move the shift lever or depress
the accelerator pedal, this could
cause an accident or fire due to
hybrid system overheating. 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 differently 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.

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.
■Sounds and vibrations specific
to a hybrid vehicle
