■Lane departure alert func-
tion
When the system determines that the vehicle might depart
from its lane or course
*, a warn-
ing is displayed on the multi-
information display, and either a
warning buzzer will sound or the
steering wheel will vibrate to
alert the driver.
When the warning buzzer sounds
or the steering wheel vibrates,
check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane.
When the system determines that
the vehicle might depart from its
lane and that the possibility of a col-
lision with an overta king vehicle in
the adjacent lane is high, the lane
departure alert will operate even if
the turn signals are operating.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb

narrow or wide.
●The vehicle is extremely tilted
due to carrying heavy luggage

When trouble arises
extremely low (approximately
below -22°F [-30°C]). ( P.75,
198)
One of the following may be the
cause of the problem:
The 12-volt battery may be
discharged. ( P.465)
The 12-volt battery terminal
connections may be loose or
corroded. ( P.396)
One of the following may be the
cause of the problem:
The 12-volt battery may be
discharged. ( P.465)
One or both of the 12-volt bat-
tery terminals may be discon-
nected. ( P.396)
Contact your Toyota dealer if
the problem cannot be repaired,
or if repair procedures are
unknown.
When the hybrid system does not start, the following steps can
be used as an interim measure
to start the hybrid system if the
power switch is functioning nor-
mally.
Do not use this starting proce-
dure except in cases of emer-
gency.
1
Pull the parking brake switch
to check that the parking
brake is set. ( P.209)
Parking brake indicator will come
on.
2 Shift the shift lever to P.
3 Turn the power switch to
ACC.
4 Press and hold the power
switch for 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 malfunction-
ing. Have the vehicle inspected
by your Toyota dealer.
The interior lights and
headlights are dim, or the
horn does not sound or
sounds at a low volume
The interior lights and
headlights do not turn on,

tem in an emergency
4677-2. Steps to take in an emergency
7
When trouble arises
recharge the 12-volt battery
of your vehicle.
6 Maintain the engine speed of
the second vehicle and start
the hybrid system of your
vehicle by turning the power
switch to ON.
7 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
8 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
9 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-vol t battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnec essary 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 you r Toyota dealer.
●Some systems may require initial-
ization. (P.512)
■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 your 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 c ontrol or the
mechanical key to lock or unlock
the doors.
●The hybrid syste m may not start
on the first attemp t after reinstall-
ing the 12-volt battery. In that
case, start the hybrid system in
the same manner as when the
electronic key does not operate
properly ( P.464). This is not a
malfunction, as the hybrid system
will start normally on the second
attempt.
●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
