The braking e.ect is limited on salt-treated roads.
Therefore, obser vethefo llowing no tes:
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

To remo vesalt build-up:
R brake occasionally while paying attention to

Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage.
Obser vethefo llowing if you must drive thro ugh
wa ter:
R The water,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at walking pace at most; water can oth-
erwise enter theve hicle interior or engine
compartment. R
Vehicles tr avelling in front, or oncoming vehi-
cles, can create waves which may exceed the
maximum permissible dep thofthewa ter.

ear axle steer
eering
ing The
rear axle steering is an elect romechanical
auxiliary steering on there ar axle which adjusts
th e steering of there ar wheels according tothe
position of the front wheels, depending on the
speed. This results in greater manoeuvrability and
impr oved driving stability, e.g. when cornering.
Re ar axle steering has thefo llowing characteris-
tics:
R reduced steering e.ort and turning circle
re sulting in reduced parking e.ort
R impr oved driving stability, e.g. when cornering
R more direct steering resulting in impr oved

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 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 201).
R Char gethe high-voltage battery if thech arge
le ve l is below 15%.
R Ifth e high-voltage battery is only used with at
low charge leve ls, fully charge the high-voltage
battery every six months.
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. Char

during braking.
Yo u ha vethefo llowing options tocharge while
stationar y:
R Ata mains soc ket (mode 2)
R Atawa llbox or charging station (mode 3)
Obser vethe di.erent grid requ irements of your
cur rent location when charging. Only use charging
cables which conform tothegr id requiremen ts.
Consult a quali/ed elect rician or your local grid
operator if you ha veany questions.
It is recommended that youch arge the high-volt-
age battery at a wallbox or charging station due to
