To set the desired departure time, touch the

corresponding function button or check the

box .

Differential protection

Introduction

The vehicle is fitted with a direct current

leakage (DC leakage) protection device. This

prevents any DC leaks that may occur during

charging from flowing into the home’s elec-

trical installation through the charging cable.

●

Departure times: Time, day of the week or

set a single or weekly departure time.

Check that the driving mode is deactivated

and that the charging cable and infrastruc-

ture are in perfect condition.

from an unsuitable electrical installation or

incorrectly handling the high-voltage bat-
