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 123).
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
ve hicle in front
To remo vesalt build-up:
R brake occasionally while paying attention to
th e tra1c conditions
R carefully depress the brake pedal at the end of

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.*

OTE
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 decrea-
ses over the course of its life. Due tothis, bo th th
e maximum electrical range that can be ach-
ie ve dby theve hicle and its maximum elect ri-
cal 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 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 If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high- voltage battery
ch arge leve l between 30% and 50%. 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 341).
R Char gethe high-voltage battery if thech arge
le ve l is below 20%.
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.
Yo u can contribute toreducing theve hicle's
ene rgy consum ption in thefo llowing ways:
R An anticipatory driving style (/ page 189)
R Reduced use of electrical consumers
R Having theve hicle regula rly main tained
