WARNING
ARNING Risk of burns due torepeatedly
switching on the seat heating
Re peatedly switching on the seat heating can
cause the seat cushion and seat backrest pad-

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
protect against overheating, the seat heating
may be temp orarily deactivated aTer it has been

ve hicle is par ked.
When theve hicle is connected topowe r supply
equipment, priority is given tocharging the 48 V
battery or the high-voltage battery toa speci/ed
minimum charge.
The running time of pre-entry climate control may
be reduced under thefo llowing conditions (vehi-

Driving and parking

If a
route event that can be dealt with more e1-
ciently byadjusting your driving style is de tected
ahead, cor responding symbol 2and theý
symbol will be displa yed in grey.
When the driver remo vesth eir foot from the
accelerator, theý symbol will turn green.
The display will disappear as soon as ECO Assist
cannot identify any fur ther recommendations
from thero ute ahead. The
following route events can be de tected by
ECO Assist:
3 Roundabout
4 S-bend 5

If th e calculated route is adhered towhen route
guidance is active, ECO Assist will operate with
gr eater accuracy. The basic function is also availa-
ble without active route guidance. Not all informa-
tion and tra1c situations can be fore seen. The
qu ality depends on the map data.
ECO Assist is only an aid. The driver is responsible
fo rke eping a safe distance from theve hicle in
front, forve hicle speed and for braking in good
time. The system may be impaired or may not function
in
thefo llowing situations:
R Ifth ere is poor visibility, e.g. due toinsu1cient
illumination of thero ad, highly variable shade
conditions, rain, sno w,fog or heavy spr ay.
R Ifth ere is glare, e.g. from oncoming tra1c,

R Ifth e windscreen in the area of the multifunc-
tion camera is dirty, or if the camera is misted
up, damaged or co vered.
R Ifth e tra1c signs are hard todetect, e.g. due
to dirt, snow or insu1cient lighting, or
because they are co vered.
R Ifth e information in the navigation system's
