Possible causes/consequences and P Solutions
Auxiliary Battery
Malfunction The auxiliary battery for the automatic transmission is no longer being
charged. X
Visit a qualified specialist workshop. X
Until then, set the automatic transmission to position P before you
switch off the engine. X
Before leaving the vehicle, apply the electric parking brake.
; Pre-Entry Climate
Ctrl. (Via Smart‐
Key) Available
Again After Engine
Start With the engine switched off, you have attempted to switch on the pre-
entry climate control more than twice. X
Let the engine run for ten seconds.
After running the engine, the pre-entry climate control is opera-
tional again.
; Pre-Entry Climate
Ctrl. (Via Smart‐
Key) Inoperative HV
Battery Low The on-board voltage is too low. The pre-entry climate control cannot
be switched on. X
Drive for a longer distance.
The battery is being charged. When the condition of charge of the
high-voltage battery is over the specified minimum, pre-entry cli-
mate control is operational again.
Warning and indicator lamps in the instrument cluster
Safety systems The information "while the engine is running" given in the vehicle Operator's Manual regarding the
signaling behavior of a warning/indicator lamp corresponds to the READY driving status. When a
warning/indicator lamp lights up in the READY driving status with the corresponding information,
the causes/consequences and solutions given in the vehicle Operator's Manual also apply to your
vehicle.48

Maintenance and care

Battery (vehicle)
Important safety notes Your vehicle is equipped with a 12 V battery and
a high-voltage battery.
For the 12 V battery, observe the notes under
"Battery (vehicle)" in the vehicle Operator's
Manual.
G DANGER
The vehicle's high-voltage electrical system is
under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
G WARNING
In the event of a vehicle fire, the internal pres-
sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.
G WARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with skin, eyes or clothing.
Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
! Exhaustive discharge caused by the vehicle
standing idle for lengthy periods can damage the high-voltage battery. If the vehicle is idle
for lengthy periods leave the high-voltage bat-
tery connected to a charging station.
If the battery charge is sufficient, the high-volt-
age battery can also supply the 12 V battery with
energy. This happens only if the battery charge
of the 12 V battery requires this, e.g. after using
electrical consumers for an extended period
with the engine switched off. As the on-board
voltage is continuously monitored this can also
be performed when the engine is switched off.
The battery charge of the 12 V battery and the
on-board voltage are thereby kept stable for
longer.
Consult an authorized Mercedes-Benz Center if
you wish to leave your vehicle parked for a long
period of time.
Charging the high-voltage battery
while the vehicle is stationary
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
! Only charge the high-voltage battery in the
"Charging when stationary" mode. Do not
connect any battery chargers to the high-volt-
age battery. This could damage the vehicle’s
high-voltage electrical system. X
Bring the vehicle to a stop with the engine
running.
The engine powers the electric motor. The
electric motor operates as a generator. The
high-voltage battery is being charged.
If the high-voltage battery has been discharged
excessively, charge the high-voltage battery to
at least 60%. In "Charging while stationary"
mode, you can monitor the condition of charge
of the high-voltage battery up to a maximum of
70% in the COMAND display and the multifunc-
tion display ( Y
