When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu-
pied vehicle, theve hicle's driving and steering
ch aracteristics change.
Yo u should bear thefo llowing in mind:
R Do not exceed the permissible roof load and
to wing capacity. Also obser vethete ch nical
data in the printed Owner's Manual.
R Evenly distribute thero of load, and place
heavy objects at the bottom. Also comply with
th e no tes on loading theve hicle
(/ page 118).
R Drive attentivel y,and avoid suddenly pulling
awa y,braking and steering as well as rapid
cornering.

R due tosalt build-up on the brake disks and
brakepads, the braking distance can increase
considerably or result in braking only on one
side
R maintain a much greater safe distance tothe

TE High-voltage battery damage due to
leaving theve hicle idle for lengt hyperiods
of time Lithium-ion batteries
experience a natural self-
dischar ge.
Exhausti vedischarging can therefore occur if
th eve hicle is idle for se veral months. This can
damage the high-voltage batter y.#
Toavo id damage, please obser vethefo l-
lowing recommendations when handling
th e high-voltage batter y.*

TE Accelerated ageing of the high-volt-
age battery As a
result of its basic characteristics, the
storage capacity of and the amount of energy
av ailable from the high-voltage battery
decrease over the course of its life. Due to th
is, bo th the maximum electrical range that
can be achie vedby theve hicle and its maxi-
mum elect rical output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage batter y:
R a high le vel of charge , especially if the
ve hicle is idle for a lengt hyperiod of time
R frequent rapid charging with direct cur rent
(mode 4)
R leaving theve hicle idle for lengt hyperiods
at high ambient temp eratures #
Toavo id accelerated ageing, please
obser vethefo llowing recommendations
when handling the high-voltage batter y. Re
commendations when handling the high-voltage
batter y:
R Only charge the high-voltage battery with
direct cur rent (mode 4) if necessar y.
R If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high- voltage battery
ch arge leve l between 25% and 30%. Do not ke
ep the high-voltage battery continuously
connected topowe r supply equipment.
R If leaving theve hicle idle for lengt hyperiods of
time avoid, if possible, high ambient temp era-
tures.
R Check the high-voltage battery's charge level
ev ery six weeks (/ page 214).
R Char gethe high-voltage battery if thech arge
le ve l is below 15%.
R Do not disconnect the 12 V battery even if the
ve hicle is leT idle for a lengt hyperiod. Other-
wise, the condition of theve hicle's high- volt-
age battery cannot be monitored.
Depending on the equipment and national ver-
sion, your vehicle is equipped with one of thefo l-
lowing vehicle soc kets:
R Type 1 forch arging with alternating cur rent
(mode 2/3)
R Type Combo 1 forch arging with alternating
cur rent (mode 2/3) and charging with direct
cur rent (mode 4)
R Type 2 forch arging with alternating cur rent

The time take nto charge the battery depends on
th ech arge status of the batter y,the ambient tem-
perature and thech arging capacity of the batter y.
The charging capacit y,in turn, depends on the
supply voltage, the cur rent intensity and the type
of po wer suppl y.
