■Heating
●In HV mode, the gasoline engine may operate in order to extract heat from
the engine coolant via the heater.
●In EV mode, heating is done by a heat pump system.
• When the outside temperature is low or it is snowing, compared to con-
ventional vehicles, heating may be less effective and warm air may not
come out.
• If frost has formed on the outside heat exchanger, the heating perfor-
mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Air Conditioning System before driv-
ing (P. 535). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When is turned on, the heating is controlled optimally. Therefore,
the set heating performance may not be achieved even if the fan speed
setting is increased.
●In the following situations the gasoline engine may operate in order to
extract heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approximately 14°F (-10°C) or low
• is operating
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■Water droplets during air conditioning operation• When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte-
rior. However, it is not a malfunction.
In this situation, the air temperature
from the outlets may not change even
though the set temperature is raised.
The outside heat exchanger, accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, it is not a malfunction.

●The shift position is in P.
●The power switch is off.
*
●All doors are closed.
●The hood is closed.
*: The Remote Air Conditioning System cannot be used for approximately 3
minutes and a half after the power switch is turned off.
■Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
●About 10 minutes have passed since operation began
●Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (traction
battery) drops to low.
■Conditions affecting operation
The system may not start in the following situations:
●The charge level of the hybrid battery (traction battery) is low
●The outside temperature is extremely low
●When the hybrid system is cool (for example, after being left for a long time
in low temperatures)
■Windshield defogger
When defogging the windshield using the Remote Air Conditioning System,
defogging may be insufficient due to the power being restricted more than
during normal air conditioning operation. Also, the outside of the windshield
may fog up due to the outside temperature, humidity or air conditioning set
temperature.
■Using the heater via the Remote Air Conditioning System
When the outside heat exchanger becomes frosted over, heating perfor-
mance may decline due to automatically switching to the frost removal opera-
tion.

AVERTISSEMENT
■Précautions relatives aux coussins gonflables SRS
Observez les précautions suivantes en ce qui concerne les coussins gon-
flables SRS.
Les négliger pourrait occasionner des blessures graves, voire mortelles.
●Le conducteur et tous les passagers du véhicule doivent porter leur cein-
ture de sécurité de la manière appropriée.
Les coussins gonflables SRS sont des dispositifs supplémentaires qui

●Le coussin gonflable SRS du conducteur se déploie avec une force consi-
dérable et peut occasionner des blessures graves, voire mortelles, notam-
ment lorsque le conducteur se trouve très près du coussin gonflable. La
National Highway Traffic Safety Administration (NHTSA), aux États-Unis,
fait les recommandations suivantes :
La zone à risque du coussin gonflable du conducteur couvre 2 à 3 in. (50
à 75 mm) de la zone de déploiement du coussin gonflable. Pour assurer
une marge de sécurité suffisante, restez à 10 in. (250 mm) du coussin
gonflable. Cette distance est mesurée depuis le centre du volant jusqu’à
votre sternum. Si maintenant vous vous tenez assis à moins de 10 in.
(250 mm), vous pouvez changer votre position de conduite de plusieurs
manières :
• Reculez votre siège à la position maximale vous permettant d’atteindre
encore aisément les pédales.
• Inclinez légèrement le dossier du siège. Bien que les véhicules soient
conçus différemment, la plupart des conducteurs peuvent maintenir une
distance de 10 in. (250 mm), même si leur siège se trouve complète-
ment vers l’avant, simplement en inclinant un peu le dossier du siège
vers l’arrière. Si la visibilité avant est moindre après avoir incliné le dos-
sier de votre siège, utilisez un coussin ferme et non glissant pour être
assis plus haut ou relevez le siège si cette option est disponible sur
votre véhicule.
• Si votre volant est réglable en hauteur, inclinez-le vers le bas. Cela
vous permet d’orienter le coussin gonflable vers votre buste plutôt que
vers votre tête et vers votre cou.
Le siège doit être réglé de la manière recommandée ci-dessus par la
NHTSA, tout en gardant le contrôle des pédales et du volant, ainsi que la
vue sur les commandes du tableau de bord.
