Driving tips
Changing gear
The automatic transmission shifts through theindividual gears automatically when it is in trans-mission position[. This automatic gear shift-ing behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts

General notes
You can change gear yourself using the steeringwheel paddle shifters. The transmission must bein position[to do this.
Depending on which steering wheel paddleshifter is pulled, the automatic transmissionimmediately shifts into the next gear down orup, if permitted.
Mercedes-AMG vehicles:to use manual shift-ing, you have two options:
Rtemporary setting
