Problems with
the transmission Problem
Possible causes/consequences and 0050
0050Solutions
The transmission has a faulty gear
shift. The transmission is losing oil. 0007
Have the transmission checked at a qualified specialist workshop immediatel y.
The acceleration characteristics are
de teriorating.
The transmission no longer shifts gear. The transmission is in emer
gency operation mode.
It is only possible toshift toone gear and reve rsege ar. 0007
Pull over and stop theve hicle, paying attention toroad and traf fic conditions. 0007
Switch the transmission toposition 005D. 0007
Switch off the engine. 0007
Wait at least ten seconds be fore re starting the engine. 0007
shift the transmission toposition 005Bor005E.
If 005B is selected, the transmission only shifts toone gear; if 005Eis selec ted, the transmission shifts to
re ve rsege ar. 0007

nction of the 4MATIC
4MATIC ensures that all four wheels are driven
when needed. Toget her with ESP ®
and 4ETS,
4MATIC impr ovesth e traction of your vehicle whene
ver a driven wheel spins due toinsuf fi‐
cient 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. 18 6
