Maneuvering
To maneuver in tight areas, e.g. when
pulling into a parking space, control the
vehicle speed by gradually releasing the
brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a vehicle out of soft ground
(mud or snow), alternately shift from
forward to reverse, while applying
slight partial throttle.
Rocking a vehicle free in this manner
may cause the ABS malfunction
indicator lamp to come on. Turn off and
restart the engine to clear the
malfunction indication.
Stopping
For brief stops, e.g. at traffic lights,
leave the transmission in gear and hold
vehicle with the service brake.
For longer stops with the engine idling,
shift into "N" or "P" and hold the
vehicle with the service brake.
When stopping the vehicle on an uphill
gradient, do not hold it with the
accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Warning!
Getting out of your vehicle with the
selector lever not fully engaged in
position "P" is dangerous. Also,
when parked on an incline, position
"P" alone may not prevent your
vehicle from moving, possibly hitting
people or objects.
Always set the parking brake in
addition to shifting to position "P".
When parked on an incline, also turn
front wheel against curb.
Emergency Operation (Limp
Home Mode)
If vehicle acceleration worsens, or
the transmission no longer shifts, the
transmission is most likely operating
in Limp Home Mode which engages
when there is a malfunction of the
transmission. This condition may be
accompanied by the "CHECK
ENGINE" malfunction indicator
lamp in the instrument cluster
coming on.
In this mode only the 2nd gear or
reverse gear can be activated.
To engage 2nd gear or reverse:
1. Stop the vehicle.
2. Move selector lever to position "P".
3. Turn off the engine.
4. Wait approx. 10 seconds.
5. Restart the engine.
6. Move selector lever to position
"D" (for 2nd gear), or move
selector lever to position "R" (for
reverse gear).
Have the transmission checked at
your authorized Mercedes-Benz
dealer as soon as possible.
