Silent Drive Away (SDA)

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

Silent Drive Away (SDA) is the ability for the customer to get in, silently start the vehicle and drive away with the engine OFF.

The transaxle is required to permit the vehicle to operate in a silent drive away mode. If both the engine coolant and the transaxle fluid temperatures are greater than 43°C (110°F) when the driver requests the vehicle to start, the vehicle will enter run mode and can be driven with the engine off.

The engine will remain off until the driver shifts out of PARK and one or more of the following conditions are met:

the vehicle speed is greater than 32 km/h (20 mph).
the distance traveled is greater than 50 m (150 ft).
the driver demanded power is greater than the lesser of either 8 kWh or the battery discharge limit existing during the silent driving event.

The engine may pull up at any time to facilitate the climate control function or to charge the high voltage battery.
