Mercedes Benz 2002 ml 320 사용자 설명서

Briefly press selector lever in the “D +” direction:
The transmission will shift from the current gear range 
to the next higher gear range.

Press and hold selector lever in the “D +” direction:
The transmission will shift from the current gear range 
directly to gear range “D”.

With transmission in gear range “D”, “4” or “3”, 
upshifting from 1st to 2nd to 3rd gear is delayed 
depending on vehicle speed and engine temperature. 
This allows the catalytic converter to heat up more 
quickly to operating temperatures.

During the brief warm-up period this delayed upshift 
and increased engine noise might be perceived as a 
malfunction. However, neither the engine nor 
transmission are negatively affected by this mode of 
operation.

The delayed upshift is effective with vehicle speeds 
below 31 mph (50 km/h) at partial throttle and engine 
temperatures below 95

°F (35°C).

To prevent the engine from laboring at low RPM when 
driving uphill gradients or with your vehicle heavily 
loaded, the automatic transmission will downshift when 
necessary to maintain engine RPM within the best 
torque range.
