■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

1904-3. Operating the lights and wipers
●To make your vehicle more visible
to other drivers during daytime
driving, the daytime running lights
turn on automatically when all of
the following conditions are met.
(The daytime running lights are
not designed for use at night.)
• The hybrid system is operating.
• The parking brake is released
• The headlight switch is in the
or
* position
*: When the surroundings are bright
The daytime running lights remain
on after they illumi nate, even if the
parking brake is set again.
●For the U.S.A.: Daytime running
lights can be turned off by operat-
ing the switch.
●Compared to turning on the head-
lights, the daytime running light
system offers gr eater durability
and consumes less electricity, so
it can help improve fuel economy.
■Headlight control sensor
The sensor may not function prop-
erly if an object is placed on the sen-
sor, or anything that blocks the
sensor is affixed to the windshield.
Doing so interfere s with the sensor
detecting the level of ambient light
and may cause the automatic head-
light system to malfunction.
■Automatic light off system
●When the headlights are on: The
headlights and tail lights turn off
30 seconds after the driver’s door
is opened and clos ed if the power
switch is turned to ACC or OFF.
(The lights turn off immediately if on the key is pressed after all
the doors are closed.)
●When only the tail lights are on:
The tail lights turn off automati-
cally if the power switch is turned
to ACC or OFF and the driver’s
door is opened.
To turn the lights on again, turn the
power switch to ON, or turn the light
switch off once and then back to
or (except for the Canada).
■Light reminder buzzer
A buzzer sounds when the power
switch is turned t o OFF or ACC and

lights are turned on.
■Windshield wiper linked head-
light illumination
When driving during daytime with
the headlight switch turned to , if
the windshield wipers are used, the
headlights will turn o n automatically
after several se conds to help
enhance the visibility of your vehi-
cle.
■12-volt battery-saving function
In order to prevent the 12-volt bat-
tery of the vehicle from discharging,
if the headlights and/or tail lights are
on when the power switch is turned
off the 12-volt battery saving func-
tion will operate and automatically
turn off all the lig hts after approxi-
mately 20 minutes. When the power
switch is turned to ON, the 12-volt
battery-saving function will be dis-
abled.
When any of the following are per-
formed, the 12-volt battery-saving
function is canceled once and then
reactivated. All the lights will turn off
automatically 20 mi nutes after the
12-volt battery-saving function has
been reactivated:
●When the headlight switch is oper-
ated
●When a door is opened or closed
