to conventional vehicles, and it is necessary
to refrain from activi ties such as sudden
acceleration. ( P.261)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be reduced, the windows
may become fogged-up, and the road
will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of wa ter between the tires
and the road surface, preventing the
steering and brakes from operating prop-
erly.
■Restraining the hybrid system output
(Brake Override System)
●When the accelerato r and brake pedals
are depressed at the same time, the
hybrid system output may be restrained.
●A warning message is displayed on the

■Possible driving distan ce when driving in
EV drive mode
EV drive mode’s possible driving distance
ranges from a few hundred meters to
approximately 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 [traction battery] level
and driving conditions.)
■Fuel economy
The hybrid system is designed to achieve
the best possible fuel economy during nor-
mal driving (using the gasoline engine and
electric motor [tractio n motor]). Driving in
EV drive mode more than necessary may
lower fuel economy.
■If “EV Mode Unavailable” is shown on
the multi-information display
The EV drive mode is not available. The rea-
son the EV drive mode is not available (the
vehicle is idling, batter y charge is low, vehi-
cle speed is higher than the EV drive mode
operating speed range or accelerator 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 automatically
canceled. The reason the EV drive mode is
not available (the batt ery 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. Drive the vehicle for a while
before attempting to turn on the EV drive
mode again.

●House lights, street lights, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.
●The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has opera- tional lights on one side

detected.
●In the following situations the system may
not be able to correctly detect the sur-
rounding brightness le vel. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually switch between the high
and low beams.
