●LDA (Lane Departure Alert)
●LTA (Lane Tracing Assist)
● LCA (Lane Change Assist) (if
equipped)
●AHB (Automatic High Beam)
●Dynamic radar cruise control
●PDA (Proactive Driving Assist)
Follow the following correction
methods.
• Check if there is any foreign mat- ter attached to the radar sensor or
radar sensor cover and clean
them if necessary ( P.286)
• The radar sensor may be mis-
aligned and will be adjusted auto-
matically while driving. Continue
driving for a while.
■If “Unavailable Activation Con-
dition not Satisfied See Owner’s
Manual” is displayed
The LCA function cannot be
used as the operating conditions
have not been met.
Operate the turn signal lever again
after all of the op erating conditions
are met.
■If “Cruise Control Unavailable
See Owner’s Manual” is dis-
played
Indicates one of the following sys-
tems is disabled.
●Dynamic radar cruise control
●Cruise control
A message is displayed when the
driving assist switch is pushed
repeatedly.
Press the driving assist switch

■If “Driver Monitor Out of Tem-
perature Range Wait until Nor-
mal Temperature” is displayed
Indicates one of the following sys-
tems is disabled.
●Driver monitor (if equipped)
●Traffic Jam Assist (if equipped)
The temperature of the driver moni-
tor camera is outside of the operat-
ing range. Wait for the temperature
to become appropriate.
■If “Driver Monitor Unavailable
See Owner’s Manual” is dis-
played
The lens of the driver monitor cam-
era may be dirty.
When there is dirt on the camera
lens, clean it with a dry, soft cloth so
as to not damage it.
■If “Engine Oil Level Low Add or
Replace” is displayed
The engine oil level may be low.
Check the level of the engine oil,
and add engine oil if necessary.
(  P.506) This message may be
displayed if the vehicle is stopped
on a slope. Move the vehicle to a
level surface and check if the mes-
sage disappears.
■If “Maintenance Required
Soon” is shown
Indicates that all maintenance
according to the driven distance on
the maintenance schedule
* should
be performed soon.
Comes on approximately 4500
miles (7200 km) after the message
has been reset.
If necessary, perform maintenance.
Please reset the message after the
maintenance is performed.
(  P.495)

5918-2. Steps to take in an emergency
8
When trouble arises
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.634)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cl eared. Before
removing the 12-volt battery termi-
nals, contact your Toyota dealer.
■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 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 system 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.588). 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
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.
●If the 12-volt battery discharges, it
may not be possible to shift the
shift position to other positions.
In this case, the vehicle can not be
towed without lifting both front
wheels because the front wheels
will be locked.
●Some systems may require initial-
ization. ( P.634)
■When replacing the 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to Europ ean regulations.
●Use a battery that the case size is
same as the previous one (LN1),
20 hour rate capacity (20HR) is
equivalent (45Ah) or greater, and
performance rating (CCA) is
equivalent (285A) 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 period where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and hybrid system may not be
able to start.
●Use a ventilation type calcium bat-
tery
●Use a 12-volt battery with a han-
dle. If a 12-volt battery without a
handle is used, removal is more
difficult.
●When removing the 12-volt bat-
tery: P.512
●After replacing, firmly attach the
following items to the exhaust hole

a group of vehicles, it may
order a recall and remedy
campaign. However, NHTSA
cannot become involved in
individual problems
between you, your dealer, or

Lampe témoin SRS
Module de capteur de coussin gonflable
Votre véhicule est doté de COUSSINS GONFLABLES ÉVOLUÉS
dont la conception s’appuie sur les normes de sécurité des véhicules
à moteur américains (FMVSS208). Le module de capteur de coussin
gonflable (ECU) contrôle le déploiement des coussins gonflables en
fonction des informations obtenues des capteurs et d’autres élé-
ments affichés dans le diagramme des composants du système ci-
dessus. Ces informations comprennent des données relatives à la
gravité de l’accident et aux occupants. Au moment du déploiement
des coussins gonflables, une réaction chimique se produit dans les
gonfleurs de coussin gonflable et les coussins gonflables se remplis-
sent rapidement d’un gaz non toxique pour aider à limiter le mouve-
ment des occupants.M

AVERTISSEMENT
■Précautions relatives aux
coussins gonflables SRS
Observez les précautions suiva-
ntes. Négliger de le faire pourrait
occasionner des blessures
graves, voire mortelles.
●Le conducteur et tous les pas-
sagers doivent porter leur cein-
ture de sécurité de la manière
appropriée.
Les coussins gonflables SRS
sont des dispos itifs supplémen-
taires qui doivent être utilisés
avec les ceintures de sécurité.
●Le coussin gonflable SRS du
conducteur se déploie avec une
force considérable et peut occa-
sionner des blessures graves,
voire mortelles, notamment lor-
sque le conducteur se trouve
très près du coussin gonflable.
La National Highway Traffic
Safety Administration (NHTSA),
aux États-Unis, fait les recom-
mandations suivantes :
La zone à risque du coussin gon-
flable du conducteur couvre
2 à 3 in. (50 à 75 mm) de la zone
de déploiement du coussin gon-
flable. Pour assurer une marge de
sécurité suffisante, restez à 10 in.
(250 mm) du coussin gonflable.
Cette distance est mesurée du
centre du volant à votre sternum.
Si votre position de conduite actu-
elle vous place à moins de 10 in.
(250 mm) du coussin gonflable du
conducteur, vous pouvez changer
votre position de plusieurs
manières :
