Toyota hybrid system combines a gaso-
line engine and electric motor power to
improve the fuel economy and minimize
the emissions as well as to provide
better power performance than the ordi-
nary gasolinepowered vehicles.
Depending on the driving condition, the
vehicle runs on the best combination of;
Gasoline engine power
Electric motor power generated by
the gasoline engine
Electric motor power of the hybrid
vehicle battery
Furthermore, the energy is efficiently used
in the following ways:
When stopping the vehicle, the gaso-
line engine is automatically stopped.
When applying the brakes or decelerat-
ing, electricity is converted from the
turning force of the wheels and stored
in the hybrid vehicle battery. (This is
called regenerative brake.)
Since the battery is charged by the
gasoline engine as needed, it does not
require charging from an outside
source like an electric vehicle.
If you do not use the vehicle for a
long time (2 weeks or more), the hy-
brid vehicle battery and auxiliary battery
will discharge and their condition is li-
able to decline. Therefore, in order to
make up for discharging, charge them
once in every 2 weeks for about 30
minutes by starting the hybrid system
with all electrical components turned off.Basic operations are described below. Be-
sides, Toyota hybrid system performs vari-
ous controls depending on the operating
condition: The “Energy Monitor” screen
tells you which power is used currently.

operating condition

Your vehicle is equipped with push but-
ton start. The hybrid system will start
automatically by pressing the “POWER”
switch briefly with the brake pedal de-
pressed.
Without smart function1. Insert the key.
2. Press the “POWER” switch briefly with the brake pedal depressed.
With smart function
1. Carry the key with you.
2. Press the “POWER” switch briefly with the brake pedal depressed.
The “READY” light flashes and stays on.
A beep sounds after a few seconds, and
the hybrid system will start. (If the ambi-
ent temperature is low such as during
winter, it may take time until the “READY”
light comes on.) You cannot start your
vehicle when the brake pedal is not de-
pressed. (For details, see “How to start
the hybrid system—” on page 230.)
The engine may not start even with the
“READY” light on. Drive your vehicle with a smooth accel-
eration and deceleration.
While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for more
efficient use, do not accelerate or de-
celerate your vehicle more than neces-
sary.
Avoid abrupt acceleration and decelera-
tion.
The remaining capacity of the hybrid
vehicle battery can be confirmed on
the energy monitor screen of the multi
−
information display. See “Information”
on page 150 for details. Gradual or
non− abrupt acceleration or deceleration
will more effectively use the benefits of
an electric motor without having to use
gasoline engine power. When parking, be sure to put the hy-
brid transaxle in “P”. While driving, use
the hybrid transaxle in “D”.
In “N”, the gasoline engine operates
but electricity cannot be generated. The
battery will be discharged requiring un-
necessary engine power to recharge.
The hybrid system automatically re-
charges the hybrid vehicle battery
when the remaining battery power is
reduced. However, the charging is not
available if the hybrid transaxle is “N”.

Energy monitor screen
Touch the “Energy” switch. Vehicle driving
condition, hybrid system operating condi-
tion and energy recovery condition are
shown.
1. Indicates the flow of energy by orange
and yellow arrows. While the energy is
recovered, the arrows change the
pointing direction and turn green.
2. Indicates the remaining capacity of the
hybrid vehicle battery.
The screen display updates every 3 sec-
onds, so it may not coincide with the
actual status.

Fuel consumption screen
Touch the “Consumption” switch. Average
fuel consumption, momentary fuel con-
sumption and recovered energy are
shown.
1.Indicates the past momentary fuel con-
sumption every 5 minutes.
2. Indicates the energy recovered for 5
minutes with symbols. One symbol re-
fers to 50 Wh or the energy by which
a 50 W bulb illuminates for an hour.
Up to 4 symbols will be shown.
3. Indicates the current momentary fuel
consumption. 4.
Indicates the average fuel consumption
after being reset. When the “Reset”
switch is touched or more than 10 L
(2.6 gal., 2.2 Imp.gal.) fuel is supplied,
the average fuel consumption is reset.

Steering pad switch operation
(with Navigation system)
The trip information screen appears direct-
ly by pressing the “INFO” button on the
right side of the steering pad. Each press
changes the “Energy Monitor” and “Con-
sumption” screens alternately.

Contrast and brightness adjustment
CONTRAST “+”:
Strengthens the contrast of the screen.
CONTRAST “–”:
Weakens the contrast of the screen.
BRIGHTNESS “+”: Brightens the screen.
BRIGHTNESS “–”: Darkens the screen.
The screen turns off when you touch the
“SCREEN OFF”. To turn the display
screen back on, push any bezel switch
such as “INFO”, etc. The selected screen
appears.
26P051b
Depending on the position of the head-
light switch, the screen changes to the
day mode or night mode.
To display the screen in the day mode
even with the headlight switch on, touch
“DAY MODE” on the adjustment screen for
brightness and contrast control.
However, if the km/h or MPH button is on,
mode switching cannot be done. It re-
mains in the day mode. In this case, “DAY
MODE” is not shown on the screen.
If the screen is set in the day mode with
the headlight switch turned to on, this
condition is memorized in the system even
with the hybrid system turned off.
