NOTICE
■
Hybrid battery (traction battery) air vents
● Do not put foreign objects near the air vents. The hybrid battery (traction
battery) may overheat, leading to a reduction in hybrid battery (traction
battery) output or a malfunction.
● Clean the air vents regularly to prevent the hybrid battery (traction battery)
from overheating.
● Do not wet or allow foreign substances to enter the air vents as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by your Toyota dealer.
● If the rear seat belt becomes separated from the guide ( P. 150), it could
obstruct the hybrid battery (traction battery) air vent. Set the rear seat belt
into the guide to use.
■ Notice about fuel
For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal.(20 L, 4.4 Imp.gal.) of fuel every 6 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 6-month period), as this
may affect components of the fuel system or the gasoline engine.
