CAUTION
General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.
Hybrid battery (traction battery)
Never resell, hand over or modify the hybrid battery (traction battery). To pre-
vent accidents, hybrid batteries (traction batteries) that have been removed
from a disposed vehicle are collected through any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional. Do not dis-
pose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting in
death or serious injury:
• The hybrid battery (traction battery) may be illegally disposed of or
dumped, and someone may touch a high voltage part, resulting in an
electric shock.
• The hybrid battery (traction battery) is intended to be used exclusively
with your hybrid vehicle. If the hybrid battery (traction battery) is used
outside of your vehicle or modified in any way, accidents such as electric
shock, heat generation, smoke generation, an explosion and electrolyte
leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident is
extremely high because the person receiving the vehicle may not be aware
of these dangers.
