WARNING Risk ofchemical burns and
poisoning from damaged high-voltage
battery
If th e housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. #
Avoid contact with the skin, eyes or
clo thing. #
Immediately rinse electrolyte splashes
off with water and seek medical atten‐
tion stra ight away. &
DANG ER Risk of explosion from exces‐
sive internal pressure of the high-voltage
battery
In theev ent of a vehicle fire ,th e internal
pressure of the high-voltage battery could
exc eed a critical value. In this case, flamma‐
ble gas escapes thro ugh a bleed valve in the
ve hicle's underbody. The
gas can ignite. #
Stop thech arging process immediately
in case of unusual odours, smo keor
burn mar ks. #
Lea vethe danger zone immediatel y.
Secu rethe danger zone at a suf ficient
di st ance. #
Call thefire service. Obser
vethefo llowing no tes on vehicle noise
emissions and the acoustic vehicle warning sys‐
te m:
R theve hicle is equipped with a purely electric
drive sy stem and de velops considerably
lo we rve hicle noise emissions than vehicles
with a combustion engine.
It is forth is reason that theve hicle is equip‐
ped with a sound generator, which ser ves as
an acoustic vehicle warning sy stem (A VAS).
R the sound generator generates speed-
dependent vehicle noise emissions when
driving forw ard and backing up at a speed of
up toaround 30 km/h. th
is helps other road users, particular ly
pede strians and bike riders, tohear your
ve hicle better.
R theve hicle acoustic warning sy stem gradu‐
ally switches off when driving at speeds
abo ve20 km/h.
R despite the sound generator, theve hicle still
may not be heard by otherroad users. Adapt
yo ur driving style accordingly.
R the sound generator is off when theve hicle
is stationar y. Manual disconnection of
the high-voltage on-
board electrical sy stem &
DANG ER Risk of fata l injury bytouching
damaged high-voltage co mponents
The vehicle's high-voltage on-board electrical
sy stem is under high voltage. If you modify
co mp onent parts in theve hicle's high-volt‐
age on-board electrical sy stem or touch dam‐
aged co mponent parts, you may be electro‐
cuted. 15 8

The component parts in
theve hicle's high-

damaged in an accident, although the dam‐
age is not visible. #
Never car ryout changes on the high-
vo ltage on-board elect rical sy stem. #
Neverto uch co mponent parts in the
high-voltage on-board electrical sy stem. #
After an accident, do not touch any
high-voltage co mponents. #
After an accident, ha vetheve hicle

Have the high-voltage on-board electri‐
cal sy stem checked at a qualified spe‐
cialist workshop. Re

Depending on the selected recuperation le vel,
th e electric mo tor is operated as an alternator
when in overru n mode and du ring braking in
order tocharge the high-voltage battery while
driving. As soon as youre lease the accelera tor
pedal when theve hicle is in motion, recupera‐
tion in overru n mode is initia ted.
The rege nerati vebrake sy stem has thefo llowing
ch aracteristics:
R suppo rts braking with an electronically con‐
trolled brake forc e boosting
R con verts th e kinetic energy of theve hicle

In the drive program, you can use thesteering

recuperation in overru n mode
(/ page 161).
Sy stem limits
The braking ef fect of the electric mo tor during
re cuperation in overru n mode may be reduced or
may not be available at all in thefo llowing situa‐
tions:
R when the high-voltage battery charge level
inc reases
R ifth e high-voltage battery is not yet at a nor‐
mal operating temp erature
R when driving at speeds close tozero
R in transmission position i
R during and af ter ESP ®
inter venes
In these cases, the desired deceleration is set by
th e brake control sy stem. Also brake with the
service brake if necessar y.
Manually setting recuperative deceleration
Yo u can use thesteering wheel gearshift paddles
to manually adju stthe intensity of recuperation
in ove rrun mode. The higher
there cuperation, the more sharply
th eve hicle is braked when coasting and the
more electrical energy is fed into the high-volt‐
age batter y.
