WARNING
QIf the hybrid system has to be turned off while driving
Turning the hybrid system off while driving will not cause a loss of steer-ing or braking control. However,
power assist for the steering wheel may be lost making it difficult to steer smoothly before stopping the vehicle
depending on the remaining charge in the 12-volt battery or usage condi-tions. Decelerate as much as possible
before turning off the hybrid system.
If the vehicle is sub-
merged or water on the
road is rising
This vehicle is not designed to
be able to drive on roads that
are deeply flooded with water.
Do not drive on roads where
the roads may be submerged
or the water may be rising. It is
dangerous to remain in the
vehicle, if it anticipated that the
vehicle will be flooded or set a
drift. Remain calm and follow
the following.

fuel. Stop the vehicle in a safe place and, if the fuel level is low, refuel the vehicle.
• “Hybrid System Stopped” • “Engine Stopped”
OIf “Maintenance required for DCDC converter cooling parts See Owner’s Manual” is shown, the filter may be
clogged, the air intake vent may be blocked, or there may be a gap in the duct. Therefore, perform the following
correction procedure. • If the air intake vent or filter of the DC/DC converter are dirty, perform
the procedures on P.479 to clean them.• If the warning message is shown
when the air intake vent and filter of the DC/DC converter are not dirty, have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

QIf “Hybrid System Overheated Out- put Power Reduced” is shown
The message may be shown when driv-
ing under severe operating conditions. (For example, when driving up a long steep hill or driving up a steep hill in
reverse.)
Coping method: P.551
QIf “Traction Battery Needs to be Protected Refrain from the Use of N
Position” is shown
This message may be displayed when the shift lever is in N.
As the hybrid battery (traction battery)
cannot be charged when the shift lever is in N, shift the shift lever to P when the vehicle is stopped.
QIf “Traction Battery Needs to be
Protected Shift into P to Restart” is shown
This message is displayed when the
hybrid battery (traction battery) charge has become extremely low because the shift lever has been left in N for a certain
amount of time.
When operating the vehicle, shift to P and restart the hybrid system.
QIf “Shift to P Before Exiting Vehi-
cle” is shown
Message is displayed when the driver’s door is opened without turning the
power switch to OFF with the shift lever in any position other than P.
Shift the shift lever to P.
QIf “Shift Out of N Release Accelera-
tor Before Shifting” is shown
Message is displayed when the acceler- ator pedal has been depressed and the
shift lever is in N. Release the accelera- tor pedal and shift the shift lever to D or R.
QIf “Press Brake when vehicle is
stopped Hybrid system may over- heat” is shown
Message is displayed when the acceler-
ator pedal is depressed to maintain the vehicle position when stopped on a upward slope, etc.
If this continues, the hybrid system may overheat.
Release the accelerator pedal and
depress the brake pedal.
QIf “Auto Power OFF to Conserve Battery” is shown
Power was turned off due to the auto-
