Controls in detail Automatic transmission* Automatic transmission is standard equipment on select models and available as optional equipment on select other models. For more information on driving with an automatic transmission see "Automatic transmission*" ( page 47). Your vehicle's transmission adapts its gear shifting process to your individual driving style by continually adjusting the shift points up or down. These shift point adjustments are performed based on current operating and driving conditions. If the operating conditions change, the automatic transmission reacts by adjusting its gear shift program. i During the brief warm-up, transmission upshifting is delayed. This allows the catalytic converter to heat up more quickly to operating temperature. The automatic transmission selects individual gears automatically, depending on: the gear selector lever position D ( page 160) with gear ranges 4, 3, 2, 1 ( page 159) the selected program mode: (C/S) ( page 162) or (M/C/S) (C 55 AMG only) ( page 165) the position of the accelerator ( page 163) the vehicle speed Gearshift pattern for automatic transmission 156
