nel
●When the lens of a headlight is
dirty and illumination is weak

broadcasting station, electric
power plant, radar equipped vehi-
cles, etc., or other location where
strong radio waves or electrical

WARNING
■Front camera installation area
on the windshield
If the system determines that the
windshield may be fogged up, it
will automatically operate the
heater to defog the part of the
windshield around the front cam-
era. When cleaning, etc., be care-
ful not to touch the area around
the front camera until the wind-
shield has cooled sufficiently, as
touching it may cause burns.

Maintenance and care
■Bulbs that need to be
replaced by your Toyota
dealer
 Headlights/daytime running
lights
 Parking lights
 Front turn signal lights
 Front side marker lights
 LED accent lights (if
equipped)
 Side turn signal lights (if
equipped)
 Tail lights
 Stop lights
 Rear side marker lights (LED
type)
 High mounted stoplight
 License plate lights
■LED light bulbs
The lights other than the rear turn
signal lights, rear side marker lights
(bulb type) and back-up lights con-
sist of a number of LEDs. If any of
the LEDs burn out, take your vehicle
to your Toyota dealer to have the
light replaced.
■Condensation build-up on the
inside of the lens
In certain situatio ns, such as when
driving in the rain or when washing
the vehicle, condensation may form
on the inner side of the headlight
lens and other li ghts. As each light
has a ventilation hole, moist air may
enter. If the ambient temperature is
low, condensation may form tempo-
rarily, but it will di ssipate as the
inside of the light i s warmed up. As
the condensation is due to a phe-
nomenon similar to windows fogging
in the rain, it doe s not indicate a malfunction.
Contact your Toyota dealer for more
information in t
he following situa-
tions:
●Large drops of water have built up
on the inside of the lens.
●Water has built up inside the
headlight.
■When replacing light bulbs

■Rear turn signal lights and
rear side marker lights
(vehicles with blub type
rear side marker lights)
1 Open the trunk lid.
2 Insert a flathead screwdriver
between the cover and the
light assembly and pry up the
cover to disengage the claws
(indicated by a dotted line).
To prevent scratching the vehicle,
wrap the tip of th e flathead screw-
driver with a cloth, etc.

4067-2. Steps to take in an emergency
One of the following may be the
cause of the problem:
Vehicles with a smart key sys-
tem: The electronic key may
not be functioning properly.
( P.408)
 There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle.
 There may be a malfunction
in the immobilizer system.
( P. 8 7 )
 Vehicles without a smart key
system: There may be a mal-
function in the steering lock
system.
 Vehicles with a smart key sys-
tem: The hybrid system may
be malfunctioning due to an
electrical problem such as
electronic key battery deple-
tion or a blown fuse. However,
depending on the type of mal- function, an interim measure
is available to start the hybrid
system. (
P.406)
One of the following may be the
cause of the problem:
 The 12-volt battery may be
discharged. ( P.410)
 The 12-volt battery terminal
connections may be loose or
corroded. ( P.323)
One of the following may be the
cause of the problem:
 The 12-volt battery may be
discharged. ( P.410)
 One or both of the 12-volt bat-
tery terminals may be discon-
nected. ( P.323)
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
If the hybrid system
will not start
Reasons for the hybrid sys-
tem not starting vary
depending on the situation.
Check the following and
perform the appropriate
procedure:
The hybrid system will not
start even though the cor-
rect starting procedure is
being followed. ( P.172)
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,
or the horn does not
sound.

(vehicles with a smart key
system)

4127-2. Steps to take in an emergency
■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 you r Toyota dealer.
●Some systems may require initial-
ization. (P.452)
■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-volt battery termi-
nals, contact your Toyota dealer.
■Charging the 1 2-volt battery
The electricity stor ed in the 12-volt
battery will discharge gradually even
when the vehicle is not in use, due
to natural discharge 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 aut omatically while
the hybrid system is operating.)
■When recharging or replacing
the 12-volt battery (vehicles
with a smart key system)
●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 system may not start
on the first att empt 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
power switch was in before the
12-volt battery discharged, be
especially careful when recon-
necting the 12-volt battery.
■When replacing t
he 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to European regulations.
●Use a 12-volt battery that the case
size is same as the previous one
(LN1), 20 hour rate capacity
(20HR) is equivalent (45Ah) or
greater, and per formance rating
(CCA) is equivalent (295A) or
greater.
• If the sizes differ, the 12-volt bat-
tery cannot be properly secured.
• If the 20 hour rate capacity is low,
even if the time p eriod where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and the hybrid system may not be
able to start.
●For details, cons ult your Toyota
dealer.
WARNING
■When removing the 12-volt
battery terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, leading to a fire
in addition to ele ctrical shocks
and death or serious injury.
