■ If “Visit Your Dealer” is shown
The system or part shown on the multi-information display is malfunctioning.
Have the vehicle inspected by your Toyota dealer.
■ If a message about an operation is shown
●If a message about an operation of the accelerator pedal or brake pedal is
shown
A warning message about an operation of the brake pedal may be shown
while the driving assist systems such as PCS (Pre-Collision System) (if
equipped) or the dynamic radar cruise control with full-speed range (if
equipped) is operating. If a warning message is shown, be sure to deceler-
ate the vehicle or follow an instruction shown on the multi-information dis-
play.
● A warning message is shown when Drive-Start Control, Brake Override Sys-
tem or Intelligent Clearance Sonar (if equipped) operates ( P. 209, 210,
352). Follow the instructions on the multi-information display.
● If a message about an operation of the power switch is shown
An instruction for operation of the power switch is shown when the incorrect
procedure for starting the hybrid system is performed or the power switch is
operated incorrectly. Follow the instructions shown on the multi-information
display to operate the power switch again.
● If a message about a shift operation is shown
To prevent the shift position from bei ng selected incorrectly or the vehicle
from moving unexpectedly, the shift position may be changed automatically
( P. 236) or operating the shift lever may be required. In this case, change
the shift position following the instructions on the multi-information display.
● If a message or image about an open/close state of a part or replenishment
of a consumable is shown
Confirm the part indicated by the multi-information display or a warning light,
and then perform the coping method such as closing the open door or

When trouble arises
■If “Shift System Malfunction See Owner’s Manual” is shown
Indicates a malfunction in the shift control system. Immediately have the sys-
tem inspected by your Toyota dealer.
The system may not operate properly.
■ If “Low 12-Volt Battery Apply Park ing Brake Securely While Parking See
Owner’s Manual” is shown
Indicates that the 12-volt battery charge is insufficient. Charge or replace the
12-volt battery.
● When the message is shown, the hybrid system may not start or the shift
position may not be changed normally. (Coping method: P. 671)
● After charging the 12-volt battery, the message may not go off until the shift
position is changed from P.
■ If “Shifting Unavailable Low 12-Volt Battery See Owner’s Manual” is
shown
Indicates that the shift position cannot be changed because the voltage of the
12-volt battery drops. Charge or replace the 12-volt battery.
(Coping method in the case the 12-volt battery is discharged: P. 711)
■ If “Hybrid System Overheated. Re duced Output Power.” is shown
The message may be shown when driving under severe operating conditions.
(For example, when driving up a long steep hill or driving up a steep hill in
reverse.)
Coping method: P. 717
■ If “Maintenance Required for Hybr id Battery Cooling Parts at Your
Dealer” is shown
There is a possibility that the filter may be clogged, the air intake vent may be
blocked, or there may be a gap in the duct. Have maintenance performed on
the hybrid battery (traction battery) cooling component at your Toyota dealer.
■ If “Hybrid Battery Low. Shift Out of to Recharge.” is shown
Message is displayed when the remaining charge for the hybrid battery (trac-
tion battery) is low.
As the hybrid battery (traction battery) can not be charged when the shift
position is in N, when stopped for long periods of time shift the shift position to
P.
■ If “Hybrid Battery Low Hybrid Syst em Stopped Shift to and Restart”
is shown
Message is displayed when the remaining charge for the hybrid battery (trac-
tion battery) is low, because vehicle has been shifted to N for a long period of
time.
When operating the vehicle, shift to P and restart the hybrid system.
■ If “Shift to Position When Parked” is shown
Message is displayed when the driver’s door is opened without turning the
power switch to off with the shift position in any position other than P.
Shift the shift position to P.
6708-2. Steps to take in an emergency
PRIUS_OM_OM47A29U_(U)■
If “Shift is in Release Acceler ator Before Shifting” is shown
Message is displayed when the accelerator pedal has been depressed and
the shift position is in N.
Release the accelerator pedal and shift the shift position to D or R.
■ If “Depress Brake When Vehicle is Stopped. Hybrid System may Over-
heat.” is shown
The message may be shown when the accelerator pedal is depressed to hold
the vehicle while the vehicle is stopped on an uphill, etc.
The hybrid system may overheat. Release the accelerator pedal and depress
the brake pedal.
■ If “Shifted to Stop Vehicle to Shift to ” is shown
●If the P position switch is pressed while driving, the shift position is changed
to N and the message is shown. ( P. 236)
● If the voltage of the 12-volt battery drops and the shift position cannot be
shown
*, the message may be shown when starting the hybrid system. In
this case, check the voltage of the 12-volt battery.
(Coping method in the case the 12-volt battery is discharged: P. 711)
*: When the voltage of the 12-volt battery drops while the shift position in P,
the front wheels may be locked by the parking lock even if the message is
shown.
■ If “Auto Power OFF to Conserve Battery” is shown
The power switch has been turned off by the automatic power off function.
When starting the hybrid system next time, operate the hybrid system for
approximately 5 minutes to recharge the 12-volt battery.
■ If “Forward Camera System Unavaila ble” or “Forward Camera System
Unavailable Clean Windshield” is displayed. *
The following systems may be suspended until the problem shown in the
message is resolved.
● PCS (Pre-Collision System)
*
●LDA (Lane Departure Alert with steering control)*
●Dynamic radar cruise control with full-speed range*
●AHB (Automatic High Beam)*

When trouble arises
Inflate the tire until the specified air pressure is reached.The sealant will be injected
and the pressure will spike to
between 44 psi (300 kPa,
3.0 kgf/cm
2 or bar) and
58 psi (400 kPa, 4.0 kgf/cm2
or bar), then gradually
decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 to 5
minutes after the switch is
turned on.
• Turn the compressor switch off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the inflation
procedure until the specified
tire inflation pressure is
reached.
• The tire can be inflated for about 5 to 20 minutes (depending on the outside temperature). If the tire inflation pressure is still lower
than the specified point after inflation for 25 minutes, the tire is
too damaged to be repaired. Turn the compressor switch off and
contact your Toyota dealer.
• If the tire inflation pressure exce eds the specified air pressure, let
out some air to adjust the tire inflation pressure. ( P. 700, 734)
With the compressor switch off, disconnect the hose from the valve
on the tire and then pull out the power plug from the power outlet
socket.
Some sealant may leak when the hose is removed.
Install the valve cap onto the valve of the emergency repaired tire.

If your vehicle overheats
■If the high coolant temperature warning light comes on or
flashes
Stop the vehicle in a safe place and turn off the air conditioning
system, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has cooled down sufficiently, inspect the
hoses and radiator core (radiator) for any leaks.
Radiator
Cooling fans
If a large amount of coolant
leaks, immediately contact
your Toyota dealer.
The following may indicate that your vehicle is overheating.
● The high coolant temperature warning light ( P. 657) comes on
or flashes, or a loss of hybrid system power is experienced. (For
example, the vehicle s peed does not increase.)
