Manual gearshift system
왘
Fully depress clutch pedal.
왘
Move the gearshift lever to shift to the desired gear without using excessive force.
왘
Select the shift range according to the model of manual transmission installed:
• 6-speed transmission, see page 70
• 9-speed transmission, see page 70
왘
Gradually release clutch pedal.
When the vehicle is stationary with the engine running and the transmission in neutral, the engine responds only
gradually to the throttle.
Risk of accident
G
You may not be able to operate the clutch or change gears properly if there is pressure loss in the ancillary
consumer circuit. This could mean that you may not be able to escape from danger areas quickly enough.
If the display shows
Œ
and the status indicator lights up yellow, do not start to move the vehicle or, if
moving, stop it as quickly as possible taking into account the traffic situation.
Have the compressed air system checked and repaired as quickly as possible at a qualified specialist
workshop possessing the required expertise and tools in order to perform the necessary safety-relevant
work.
Mercedes-Benz recommends a Mercedes-Benz service center for this work. It is absolutely essential that all
safety-relevant work and all work on safety-relevant systems is performed by a qualified specialist workshop.
!
When changing gear make sure that the engine speed does not rise to the red danger area on the
tachometer.
Always release the gearshift lever when the shift operation is complete and do not rest your hand or arm on
the gearshift lever. You might otherwise damage the transmission.
If the warning buzzer sounds when shifting down, the maximum permissible engine speed has been
exceeded. Do not let in the clutch, but select a higher gear (risk of clutch and engine damage due to
overrevving). To protect the transmission synchronization the power assistance for the gearshift is
deactivated automatically. This means that greater force is required to operate the gearshift lever.
Only engage reverse gear when at idle speed with the vehicle stationary.
Driving with very low or very high engine speeds will damage the engine.
