So you have a fancy Jaguar? Your car may have a deployable door handle. How does it work? You just have to press the unlock button on your smart key to have your door handle deployed. Just pull the handle to enter your car. If your car has a keyless entry system, just press the front of your door handle, and it will be deployed. The deployable handles will retract when you exceed a pre-determined speed limit. One of those fancy features that not everyone needs but would be fun to have.
