One of the following may be the
cause of the problem:
 The AC charging cable may be
attached to the vehicle.
( P.135)
 The electronic key may not be
functioning properly. ( P.571)
 There may not be sufficient fuel
in the vehicle’s tank.
Refuel the vehicle. ( P.336)
 There may be a malfunction in
the immobilizer system. ( P.77)
 There may be a malfunction in
the steering lock system (if
equipped).
 The hybrid system may be mal-
functioning due to an electrical
problem such as electronic key
battery depletion or a blown fuse.
However, depending on the type
of malfunction, an interim mea-
sure is available to start the
hybrid system. ( P.569)
NOTICE
■Driving with tire chains and the compact spare tire

5708-2. Steps to take in an emergency
1Remove the cover inside the
luggage compartment by insert-
ing a screwdriver.

Using the lever to open the fuel filler
door may not allow for an adequate reduction in fuel tank pressure before refueling. To prevent fuel from spilling
out, turn the cap slowly when removing it.
During refueling, fuel may spill out from
the filler opening due to air being dis- charged from inside the fuel tank.

New genuine keys can be
made by any authorized
Toyota retailer or Toyota
authorized repairer, or any reli-
able repairer using the other
key and the key number
stamped on your key number
plate. Keep the plate in a safe
place such as your wallet, not
in the vehicle.

risk of vehicle theft increases signifi- cantly. Visit any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer immediately with all remaining electronic keys that were provided with your vehicle.
If the fuel filler door can-
not be opened
If the fuel filler door opener
switch cannot be operated,

tion: Open 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” indica-
tor comes on. If the indicator
light does not come on, contact
any authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
9 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were con-
nected.
10 Close the exclusive jump start-
ing terminal cover, and reinstall
the fuse box cover to its original
position.
Once the hybrid system starts,
have the vehicle inspected at any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■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 dis-charge
●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.
■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 any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
●Some systems may require initializa-
tion. ( P.609)
■When removing the 12-volt battery terminals

removed, the information stored in the ECU is cleared. Before removing the 12-volt battery terminals, contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Charging the 12-volt battery
The electricity stored in the 12-volt bat- tery 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 vehi-cle is left for a long time, the 12-volt bat-
tery may discharge, and the hybrid system may be unable to start. (The 12-volt battery recharges automatically
while the hybrid system is operating.)
■When recharging or replacing the 12-volt battery
●In some cases, it may not be possible to unlock the doors using the smart entry & start system when the 12-volt
battery is discharged. Use the wire- less remote control or the mechanical key to lock or unlock the doors.
