Charging hybrid battery
When the hybrid battery power is insuffi-
cient, the gasoline engine charges the hy-
brid battery. The system always supplies
electricity at a constant level. Your vehicle is equipped with push but-
ton start system. The hybrid system
will start automatically by pressing 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.
Without smart function
1. Insert the key.
2. Press the “POWER” switch briefly with the brake pedal depressed.
The “READY” light flashes and stays on.
Two beeps sound after a few seconds,
and the hybrid system will start. (If the
ambient 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 348.)
The engine may not start even with the
“READY” light on.
Starting your vehicle

15

As the vehicle runs with both the gaso-
line engine and electric motor, you may
hear a motor sound coming from the
engine compartment.
When the hybrid system is started or
stopped, you may hear a sound coming
from the hybrid battery in the luggage
compartment. However, this does not
indicate any trouble.
If the “READY” light is on, you can
start even though the gasoline engine
may be off.
When you shift the shift lever to “B”
and release it to its original position
and your foot from the accelerator ped-
al, engine braking will be applied. How-
ever, during high speed driving you
may feel that deceleration by engine
braking is less than that of ordinary
vehicle.
Be sure to put the hybrid transaxle in
“P” when parking.
In “N”, the hybrid battery assembly is not
charged, even if the gasoline engine is
operating. You cannot run your vehicle if
the hybrid transaxle is left in “N” for a
long time because the hybrid battery as-
sembly will be discharged. When you leave your vehicle, apply the
parking brake to put the hybrid trans-
axle in “P” and be sure to carry the
key with you and lock all the doors.
If you leave the hybrid system in “ACC”
or “IG
−ON”, the hybrid system may not
start because the 12 volt battery will be
discharged.
If the vehicle is parked for a long time,
the hybrid battery will discharge gradually.
To keep the hybrid battery in good condi-
tion, drive the vehicle at least once every
several months for at least 30 minutes or
ten miles. If the hybrid battery becomes
fully discharged and the vehicle will not
start even with a jump −start to the 12 volt
battery, contact your Toyota dealer.
CAUTION
When you leave your vehicle, be
sure to shut off the hybrid system.
Be sure to put the hybrid transaxle
in “P” because the vehicle can start
with the “READY” light on and the
engine stopped (no engine sound
and vibration). When the “READY”
light is on, if you leave your ve-
hicle in shift position other than
“P” and “N”, the vehicle will creep
and start abruptly with the accelera-
tor pedal being depressed by mis-
take. This may cause death or seri-
ous injury.
