nary tense.
• Do not start off the vehicle by mistake.
●Do not refuel or wash the vehi-

rosive gases or fluids are gener-
ated.

matically when the remaining
charge of the hybrid battery
(traction battery) decreases.
When using a power outlet in an
area with poor ventilation or an
enclosed area, such as a
garage or a place where snow
has piled up, properly use an air
intake and exhaust device to
prevent lack of oxygen and full-
ness of exhaust gas. If such
device cannot be used, do not
use the power outlet.

driving
●In situations such as the follow-
ing, do not use an electric
device while driving. Also, do

case of sudden braking or an
accident
• When a device is likely to cause fire if it falls or generates heat
