WARNING

Warnings for using My Room Mode

Observe the following precautions.
Failure to do so may result in death or a

serious health hazard.

Do not leave children, people who

need care, or pets inside the vehicle.

The temperature inside the vehicle

may become high or low due to fea-

tures such as the automatic shut-off.

The children, people who need care,

or pets left inside the vehicle may suf-

fer heatstroke dehydration or hypoth-

ermia. Also, since the wipers, etc., can

be operated, there may be accidental

operation, possibly leading to an acci-

dent.

form the appropriate correction procedures.

Likely cause

Correction procedure

“Climate Prep” is set to “On”

When “Climate Prep” is set to “On”, the air
conditioning operates until the time set in
“Departure”. Therefore, charging may not
complete by the set time due to charging
conditions. To have the traction battery fully
charged, allow charging to continue.

Charging end time does not match esti-
mated end time due to condition of power
source or outside temperature

If sudden changes in temperature or
changes in the condition of the power
source occur while charging, charging may
not end exactly at the time estimated by the

functions

have been used and the remain-

ing charge is now reduced.

: Electricity is consumed when the air con-

ditioning-linked function, traction battery
heater, My Room Mode or Remote Air
Conditioning System is operating.
