If people, particular lych ildren, are exposed
to extreme temp eratures over an extended
pe riod of time, there is a risk of serious
injury or danger tolife. #
Never lea vepersons, children in partic‐
ular, unat tended in theve hicle. The
vehicle interior can be air conditioned when
th eve hicle is par ked.
When theve hicle is connected topowe r supply
equipment, priority is given tocharging the high-
vo ltage battery toa specified minimum charge. The
running time of pre-entry clima tecontrol
may be reduced under thefo llowing conditions:
R The vehicle is not connected topowe r supp ly
equipment.
R The high-voltage battery is not charge d suf fi‐
ciently.
Wi th active pre-ent ryclimate control, thech arge

The brake fluid cons tantly absorbs moi sture
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va pour poc kets may form inthe brake sys‐
te m when the brakes are applied hard.
This impairs the braking ef fect. #
Have the brake fluid rene we d at the
