switching on the seat heating
Re peatedly switching on the seat heating can
cause the seat cushion and seat backrest pad-
ding tobecome very hot.
In particular, the health of persons with limited
te mp erature sensitivity or a limited ability to
re act tohigh temp eratures may be a.ected or
th ey may even su.er burn-like injuries. #
Do not repeatedly switch on the seat
heating. To

Cruise control may be unable tomaintain the

speed is resumed when thegr adient evens out.
Increase recuperation in good time on long and
steep downhill gradients. Take particular no teof

will make use of the electric mo tor's braking

WARNING
ARNING Risk of an accident due to
va pour poc kets form ing in the brake sys-
tem
The brake 0uid constantly absorbs moisture
from the air. This lo wersthe boiling point of
th e brake 0uid. If the boiling point is too lo w,
va pour poc kets may form inthe brake system
when the brakes are applied hard.
This impairs the braking e.ect. #
Have the brake 0uid rene we d at the
