requirements and activation con‐
ditions are fulfilled, the best possible accelera‐
tion can be achie ved from a standstill.
Do not use the optimised acceleration on public
ro ads. Individual wheels could spin and youcould lose control of
theve hicle. There is an
increased risk of skidding and/or accident.
Be sure toobser vethe saf ety no tes and informa‐

WARNING Risk of skidding and having
an accident from wheels spinning
When you use optimised acceleration, indi‐
vidual wheels could spin and you could lose
cont rol of theve hicle.
If ESP ®
is deactivated, there is a risk of skid‐
ding and accident! #
Make sure that no persons or obstacles
are in the close vicinity of your vehicle. Re

DANG ER Risk of fata l injury due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐

an adequate supply of fresh air. &
WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the

nction of the 4MATIC
4MATIC ensures that all four wheels are driven.
To get her with ESP ®
and 4ETS, 4MATIC impr oves
th e traction of your vehicle whene ver a driven
wheel spins due toinsuf ficient traction.
If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor over‐
ri de the la wsof ph ysics. 4MATIC cannot take
account of road, weather and traf fic conditions.
4MATIC is only an aid. You are responsible espe‐
cially for maintaining a safe dis tance from the
ve hicle in front, forve hicle speed, for braking in
good time and forst ay ing in lane.
% In wint ryroad conditions, the maximum
ef fect of 4MATIC can be achie ved only if you
