Function of the 4MATIC

The flexible all-wheel distribution of the 4MATIC
means the drive is always ideally distributed
between both axles. Depending on the situation,
only the front axle or only the rear axle can be
driven, or the drive can be distributed continu-
ously between both axles.
This means that recuperation can be used even
more effectively and the range of the vehicle can
be increased ( page 270).

®
Together with ESP and 4ETS, 4MATIC improves
the traction of your vehicle whenever a driven
wheel spins due to insufficient traction.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor override
the laws of physics. It cannot take into account
road, weather or traffic conditions. 4MATIC is only
an aid. You are responsible especially for main-
taining a safe distance from the vehicle in front,
for vehicle speed, for braking in good time and for
staying in lane.

In wintry road conditions, the maximum effect
of the flexible all-wheel distribution can be
achieved only if you use winter tyres (M+S
tyres), with snow chains if necessary.

Charging the high-voltage battery

Notes on charging the high-voltage battery
* NOTE High-voltage battery damage due to
leaving the vehicle idle for lengthy periods
of time
Lithium-ion batteries experience a natural self-
discharge.
Exhaustive discharging can therefore occur if
the vehicle is idle for several months. This can
damage the high-voltage battery.
To avoid damage, please observe the fol-
#
lowing recommendations when handling
the high-voltage battery.
* NOTE Accelerated ageing of the high-volt-
age battery due to not observing the fol-
lowing recommendations
As a result of its basic characteristics, the
storage capacity of, and the amount of energy
available from, the high-voltage battery
decreases over the course of its life. As a
