Automatic transmission*
Downshifting
̈ Briefly press the gear selector lever to
the left in the D- direction.
The transmission will shift from the current
gear to the next lower gear as permitted by
the shift program. This action simulta-
neously limits the gear range of the
transmission (
୴ page 166).
Upshifting
̈ Briefly press the gear selector lever to
the right in the D+ direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simul-
taneously extends the gear range of the
transmission.
Canceling gear range limit
̈ Press and hold the gear selector lever
in the D+ direction until
D
reappears in
the multifunction display.
The transmission will shift from the current
gear range directly to gear range D.
Shifting into optimal gear range
̈ Press and hold the gear selector lever
in the D- direction.
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This may
involve shifting down one or more gears.
Emergency operation (Limp Home
Mode)
If vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home (emergency operation) mode. In this
mode only second gear and reverse gear
can be activated.
̈ Stop the vehicle in a safe location.
̈ Move gear selector lever to P.
̈ Turn off the engine.
̈ Wait at least 10 seconds before
restarting.
̈ Restart the engine.
̈ Move gear selector lever to position D
(for second gear) or R.
̈ Have the transmission checked at an
authorized Mercedes-Benz Center as
soon as possible.
Warning! G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
i
To avoid overrevving the engine when
the gear selector lever is moved to
the D- direction, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.
