Handling method: P. 4 8 4
■If “Traction Battery Needs to be
Protected Refrain from the Use
of N Position” is displayed
This message may be displayed
when the shift lever is in N.
As the hybrid batte ry (traction bat-
tery) cannot be charged when the
shift lever is in N, shift the shift lever
to P when the vehicle is stopped.
■If “Traction Battery Needs to be
Protected Shift into P to
Restart” is displayed
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

When trouble arises
3Turn the tire jack portion
by hand until the notch of the
jack is in contact with the jack
point.
The jack point guides are located
under the rocker panel. They indi-
cate the jack po int positions.
4Raise the vehicle until the tire
is slightly raised off the
ground.
5 Remove all the wheel nuts
and the tire.
When resting the tire on the
ground, place the tire so that the
wheel design faces up to avoid scratching the wheel surface.
■If the spare tire cannot be low-
ered
If the spare tire cannot be lowered, it
may not have been stowed properly.
Perform the following procedure:
1 Fully tighten the spare tire clamp
bolt by turning the jack handle
clockwise until two clicks are
heard and the jack handle skips.
2 Turn the jack handle counter-
clockwise to lower the spare tire.
If the spare tire still cannot be low-
ered, attempt to fully tighten the
spare tire clamp bolt again by turn-
ing the jack handle clockwise. Then
turn it counterclockwise at least 2
turns to lower the spare tire.
If the spare tire still cannot be low-
ered, the wire cable may be sev-
ered. Have the vehicle inspected by

6 Using the jack handle and
adapter socket, tighten the
tire clamp bolt by turning it
clockwise until the tire is in
the correct position and two
clicks are heard as the jack
handle skips.
7 Confirm it is not loose after
tightening:
1 Push and pull the tire

■The compact spare tire
●The compact spare tire is identi-
fied by the label “TEMPORARY
USE ONLY” on the tire sidewall.
Use the compact spare tire tempo-
rarily, and only in an emergency.
●Make sure to check the tire infla-
tion pressure of the compact
spare tire. ( P.495)
■When using the compact spare
tire
As the compact spare tire is not
equipped with a tire pressure warn-
ing valve and transm itter, low infla-
tion pressure of t he spare tire will
not be indicated by the tire pressure
warning system. Also , if you replace
the compact spare ti re after the tire
pressure warning light comes on,
the light remains on.
■When the compact spare tire is
equipped
When driving with the compact
spare tire installed, the vehicle
height will be diffe rent than when
driving with standard tires.
■If you have a flat front tire on a
road covered with snow or ice
Install the compact spare tire on one
of the rear wheels of the vehicle.

 There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle.
 There may be a malfunction
in the immobilizer system.
( P. 7 7 )
 The hybrid system may be
malfunctioning due to an elec-
trical problem such as elec-
tronic key battery depletion or
a blown fuse. However,
depending on the type of mal-
function, an interim measure
is available to start the hybrid
system. ( P.474) One of the following may be the
cause of the problem:

The 12-volt battery may be
discharged. ( P.479)
 The 12-volt battery terminal
connections may be loose or
corroded. ( P.402)
One of the following may be the
cause of the problem:
 One or both of the 12-volt bat-
tery terminals may be discon-
nected. ( P.402)
 The 12-volt battery may be
discharged. ( P.479)
Contact your Toyota dealer if the
problem cannot be repaired, or if

When trouble arises
6Open and close any of the
doors of your vehicle with the
power switch OFF.
7 Maintain the engine speed of
the second vehicle and start
the hybrid system of your
vehicle by turning the power
switch to ON.
8 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
9 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
10 Close the exclusive jump
starting terminal cover, and
reinstall the fuse box cover to
its original position.
Once the hybrid system starts,
have the vehicle inspected at
your Toyota dealer as soon as
possible.
■Starting the hybrid system
when the 12-volt battery is dis-
charged
The hybrid system cannot be started
by push-starting.
■To prevent 12-volt battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the 12-volt battery is
removed or discharged
●Information stored in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at your Toyota dealer.
●Some systems may require initial-
ization. ( P.523)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cleared. Before
removing the 12-vo lt battery termi-
nals, contact you r Toyota dealer.
■Charging the 12-volt battery
The electricity stored in the 12-volt
battery will discha rge gradually even
when the vehicle i s not in use, due
to natural dischar ge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the hybrid system may
be unable to start. (The 12-volt bat-
tery recharges automatically while
the hybrid system is operating.)
■When recharging or replacing
the 12-volt battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the
12-volt battery is discharged. Use
the wireless remote control or the
mechanical key to lock or unlock
the doors.
●The hybrid syste m may not start
on the first attempt after the
12-volt battery has recharged but
will start normally after the second
attempt. This is not a malfunction.
●The power switch mode is memo-
rized by the vehicle. When the
12-volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
If you are unsure what mode the
