tery temperature.Wait for battery warm-
up to be completed.
Pre-climate operations
were aborted due to the
amount of charge
remaining in the traction
battery being low.
Charge the vehicle.

■ Charging Message Details
Depending on operation conditions, the details of a message shown on the
multi-information display and actual vehicle conditions may differ (for exam-
ple the previous condition may be shown). However, the following are not a
malfunction:
If “Charging Not Available Due to IG On turn IG Off to Charge” is shown on
the multi-information display, the message may still be displayed even after
the “POWER” switch is turned off once, the charging cable is reconnected
and the “POWER” switch is turned to ON mode again. However, if the charg-
ing indicator lights are illuminated or flashing ( P. 63), charging has recom-
menced correctly.
If “Canceled” is shown on the multi-in formation display, pre-climate opera-
tions stopped partway through due to the system judging that 15 minutes of
pre-climate operations was unnecessary . For example, soon after pre-cli-
mate operations started, the cabin temperature reached the set temperature
and pre-climate operations were stopped early.
When pre-climate has completed operations normally, “Complete” is shown
on the multi-information display.
