Starting the hybrid system
Depress the brake pedal. Touch the Toyota emblem side of
the electronic key to the
“POWER” switch.
If any of the doors is opened or
closed while the key is being
touched to the switch, an alarm
will sound to indicate that the start
function cannot detect the elec-
tronic key.
Press the “POWER” switch within 10 seconds of the buzzer
sounding, keeping the brake pedal depressed.
In the event that the hybrid system still cannot be operated, contact
your Toyota dealer.
STEP 1
STEP 2
■ Stopping the hybrid system
Set the parking brake, shift the shift position to P and press the “POWER”
switch as you normally do when stopping the hybrid system.
■ Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the
electronic key battery be replaced immediately when the battery is depleted.
(P. 460)
■ Changing “POWER” switch modes
Within 10 seconds of the buzzer sounding, release the brake pedal and
press the “POWER” switch.
The hybrid system does not start and modes will be changed each time the
switch is pressed. ( P. 196)

■
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic.
■ When the 12-volt battery is removed or discharged
●The hybrid system may not start. ( P. 439)
● If the 12-volt battery is depleted with the shift position in P, it will not be
possible to shift the shift position other than P. In this case, the vehicle
cannot be towed without lifting both front wheels because the front
wheels are locked by the parking lock. ( P. 491)
● When the 12-volt battery is reconnected, start the hybrid system, depress
the brake pedal, and confirm that it is possible to shift into each shift posi-
tion.
■ Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even
when the vehicle is not in use, due to natural discharge and the draining
effects of certain electrical appliances. If the vehicle is left for a long time, the
12-volt battery may discharge, and the hybrid system may be unable to start.
(The 12-volt battery recharges automatically while the hybrid system is oper-
ating.)

If the vehicle becomes stuck
CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the sur-
rounding area is clear to avoid striki ng other vehicles, objects or people. The
vehicle may also lunge forward or lu nge back suddenly as it becomes free.
Use extreme caution.
■ When changing the shift position
Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any positions other than P or N may cause the
vehicle to accelerate abruptly, causing an accident and resulting in death or
serious injury.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Set the parking brake and shift the shift position to P. Stop
the hybrid system.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material under the tires
to help provide traction.
Restart the hybrid system.
Shift the shift position to D or R, release the parking brake
and carefully apply the accelerator to free the vehicle.STEP 1

If your vehicle has to be stopped in an emergency
Only in an emergency, such as if it becomes impossible to stop the
vehicle in the normal way, stop the vehicle using the following pro-
cedure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Shift the shift position to N.
If the shift position is shifted to N After slowing down, stop the vehi cle in a safe place by the
road.
Stop the hybrid system.
If the shift position cannot be shifted to N Keep depressing the brake pedal with both feet to reduce
vehicle speed as much as possible.
To stop the hybrid system,
press and hold the “POWER”
switch for 2 consecutive sec-
onds or more, or press it
