■When continually using EV mode only
After driving for approximately 124 miles (200 km) with the gasoline engine
off, the gasoline engine may start for a short amount of time in order to pro-
tect the system.
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions*:
●During gasoline engine warm-up
●When the temperature of the hybrid battery (traction battery) is high or
low
●During hybrid battery (traction battery) charging
●When the heater is switched on
*:Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.
CAUTION
■While driving
Because there is no engine noise when the vehicle is being driven using the
electric motor, pedestrians in the vicinity may not notice the vehicle. Even
though the vehicle is equipped with the vehicle proximity notification system,
drive with care as pedestrians in the vicinity may still not notice the vehicle if
the surrounding area is noisy.

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, it could obstruct
the hybrid battery (traction battery) air vent. Set the rear seat belt into the
guide to use.
There are air intake vents on the side of
the rear right seatback and on the front
corner of the left rear seat cushion for the
purpose of cooling the hybrid battery
(traction battery). If the vents become
blocked, the hybrid battery (traction bat-
tery) may overheat, leading to a reduction
in hybrid battery (traction battery) output.
