CAUTION
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indi cate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
NOTICE
■Precaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres-
sure warning system may not operate properly.

If the hybrid system will not start
Reasons for the hybrid system not starting vary depending on the
situation. Check the following a nd perform the appropriate proce-
dure:
■ The hybrid system will not start, even though the correct
starting procedure is being followed. ( P. 183, 188)
One of the following may be the cause of the problem.
● The electronic key may not be functioning properly. ( P. 596)
● There may be a malfunction in the immobilizer system.
( P. 125)
● There may be a malfunction in the steering lock system.
● The hybrid system may be malfun ctioning due to an electrical
problem such as an open circuit or a blown fuse. However,
depending on the type of malf unction, an interim measure is
available to start the hybrid system. ( P. 593)
■ The interior lights and headlights are dim, or the horn does
not sound or sounds at a low volume.
One of the following may be the cause of the problem.
●The 12-volt battery may be discharged. ( P. 598)
● The 12-volt battery terminal c onnections may be loose or cor-
roded.

Emergency start function (vehicles with smart key system)
When the hybrid system does not start, the following steps can be
used as an interim measure to st art the hybrid system if the
“POWER” switch is functioning normally.
Set the parking brake.
Shift the shift lever to P.
Turn the “POWER” switch to ACCESSORY mode.
Push and hold the “POWER” switch about 15 seconds while
depressing the brake pedal firmly.
Even if the hybrid system can be started using the above steps, the
system may be malfunctioning. Ha ve the vehicle checked by your
Toyota dealer.
■ The interior lights and headlights do not turn on, or the horn
does not sound.
One of the following may be the cause of the problem.
●One or both of the 12-volt ba ttery terminals may be discon-
nected.
● The 12-volt battery may be discharged. ( P. 598)
Contact your Toyota dealer if the problem cannot be repaired, or if
repair procedures are unknown.

■
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, etc.
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately 5
minutes to recharge the 12-v olt battery of your vehicle.
Vehicles with smart key system:
Open and close any of the doors with the “POWER” switch
OFF.
Vehicles without smart key system:
Maintain the engine speed of the second vehicle and turn
the engine switch to the “ON” position, then start the hybrid
system.
Vehicles with smart key system:
Maintain the engine speed of the second vehicle and turn
the “POWER” switch to ON mode, then start the hybrid sys-
tem.
Make sure the “READY” indicator comes on. If the indicator
does not comes on, contact your Toyota dealer.
Once the hybrid system has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the hybrid system starts, ha ve the vehicle inspected at your
Toyota dealer as soon as possible.STEP4

■When the 12-volt battery is removed or discharged
●The hybrid system may not start. ( P. 512)
● The power back door must be initialized. ( P. 75)
● Make sure that the key is not inside the vehicle when recharging or
replacing the battery. The key may be locked in the vehicle if the alarm is
activated. ( P. 131)
■ 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.)
CAUTION
■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the 12-volt battery.
●Make sure each jumper cable is connected to the correct terminal.
● Do not allow the ends of the jumper cable used for the “+” terminals to
come into contact with any other parts or metal surface in the area, such
as brackets or unpainted metal.
● Do not allow the “+” and “-” terminals of the jumper cables to come into
contact with each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the 12-volt battery.
