than P.
●After the vehicle is parked, if the
door is locked with the door lock
switch (P.131) from the inside or
the mechanical key ( P.408) from
the outside, the automatic hybrid
system shut off fea ture will be dis-
abled. The timer for the automatic
hybrid system shu t off feature will
be re-enabled if the driver’s door
is opened.
WARNING
■Stopping the hybrid system
in an emergency
●If you want to stop the hybrid
system in an emergency while
driving the vehicle, press and
hold the power switch for more
than 2 seconds, or press it
briefly 3 times or more in suc-
cession. (
P.363)
However, do not touch the
power switch while driving
except in an emergency. Turn-
ing the hybrid system off while
driving will not cause loss of
steering or braking control, how-
ever, power assist to the steer-
ing will be lost. This will make it
more difficult to steer smoothly,
so you should pull over and stop
the vehicle as soon as it is safe
to do so.
●If the power switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-info rmation display
and a buzzer sounds.
●To restart the hybrid system
after performing an emergency
shutdown, shift the shift lever to
N and then press the power
switch.
■When parking
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time. If such a situation
cannot be avoided, park the
vehicle in an open space and
ensure that exhaust fumes do
not enter the vehicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem is operating, exhaust gases
may collect and enter the vehi-
cle.

●The hybrid battery (traction bat-
tery) becomes low.
The remaining battery level indi-
cated in the energy monitor dis-
play is low. ( P. 1 1 8 )
●Vehicle speed is high.
●The accelerator pedal is
depressed firmly or the vehicle is
on a hill etc.
■Possible driving distance when
driving in EV drive mode
EV drive mode’s possible driving
distance ranges from a few hundred
meters to approxima tely 0.6 mile (1
km). However, depending on vehicle
conditions, there are situations
when EV drive mode cannot be
used.
(The distance that is possible
depends on the hybrid battery [trac-
tion battery] level and driving condi-
tions.)
■Fuel economy
The hybrid system is designed to
achieve the best possible fuel econ-
omy during normal driving (using
the gasoline engi ne and electric
motor [traction motor]). Driving in
EV drive mode more than neces-
sary may lower fuel economy.
■If “EV Mode Unavailable” is
shown on the multi-information
display
The EV drive mode is not available.
The reason the EV drive mode is
not available (the vehicle is idling,
battery charge is low, vehicle speed
is higher than the EV drive mode
operating speed range or accelera-
tor pedal is depressed too much)
may be displayed. Use the EV drive
mode when it becomes available.
■If “EV Mode Deactivated” is
shown on the multi-information
display
The EV drive mode has been auto-
matically canceled. The reason the
EV drive mode is not available (the
battery charge is low, vehicle speed
is higher than the EV drive mode operating speed r
ange or accelera-
tor pedal is depressed too much)
may be displayed. Drive the vehicle
for a while before attempting to turn
on the EV drive mode again.
WARNING
■Caution while driving
When driving in EV drive mode,
pay special attention to the area
around the vehicle. Because
there is no engine noise, pedestri-
ans, people riding bicycles or
other people and vehicles in the
area may not be aware of the
vehicle starting off or approaching
them, so take extra care while
driving. Therefore, take extra care
while driving even if the vehicle
proximity notification system is
active.

WARNING
■When driving on slippery
road surfaces
Do not accelerate or shift gears
suddenly.
Sudden changes in engine brak-
ing may cause the vehicle to spin
or skid, resulting in an accident.
NOTICE
■Hybrid battery (traction bat-
tery) charge
If the shift lever is in N, the hybrid
battery (traction battery) will not
be charged even when the engine
is running. Therefore, if the vehi-
cle is left with the shift lever in N
for a long period of time, the
hybrid battery (traction battery)
will discharge, and this may result
in the vehicle not being able to
start.
