WARNING

■

When starting the hybrid system

Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any
circumstances.
Doing so may cause an accident resulting in death or serious injury.

■

Stopping the hybrid system in an emergency

●

If you want to stop the hybrid system in an emergency while driving the
vehicle, press and hold the power switch for more than 2 seconds, or
press it briefly 3 times or more in succession. (



P. 661)

However, do not touch the power switch while driving except in an emer-
gency. Turning the hybrid system off while driving will not cause loss of
steering or braking control, however, power assist to the steering will be
lost. This will make it more difficult to steer smoothly, so you should pull
over and stop the vehicle as soon as it is safe to do so.

●

If the power switch is operated while the vehicle is running, a warning
message will be shown on the multi-information display and a buzzer
sounds.

●

When restarting the hybrid system after an emergency shutdown while
driving, press the power switch. When restarting the hybrid system after
stopping the vehicle, change the shift position to P and then press the
power switch.

■

When parking

Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle and may
lead to an accident caused by light-headedness, or may lead to death or a
serious health hazard.

●

If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the hybrid system.

●

Do not leave the vehicle with the hybrid system operating for a long time. If
such a situation cannot be avoided, park the vehicle in an open space and
ensure that exhaust fumes do not enter the vehicle interior.

●

Do not leave the hybrid system operating in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle while the
hybrid system is operating, exhaust gases may collect and enter the vehi-
cle.

For the shift positions

●

When the power switch is off, the shift position cannot be changed.

●

When the power switch is in ON mode (the hybrid system is not operating),
the shift position can only be changed to N. The shift position will be
changed to N even if the shift lever is shifted to D or R and held in that posi-
tion.

●

When the “READY” indicator is on, the shift position can be changed from P
to D, N or R.

●

When the “READY” indicator is flashing, the shift position cannot be
changed from P to another position even if the shift lever is operated. Wait
until the “READY” indicator changes from a flashing to a solid light, and then

resulting in an accident.

■

Shift lever and P position switch

●

Do not remove the shift lever knob or use anything but a genuine Toyota
shift lever knob. Also, do not hang anything on the shift lever.
