Enjoy our great Arizona weather with the top down and the wind through your hair! Experience the refinement of Mercedes in this highly responsive sport-tuned two-seat roadster. Upgraded radio includes Apple Carplay/Android Auto (which allows navigation), Bluetooth, two USB ports, and SD card input. Press the go-pedal and let the 6-cylinder 228 horsepower/221 torque zoom you into our wide-open spaces. Put the power hardtop up in 22 seconds to quiet the cabin into a comfortable cruiser, taking control via the shifter of the 7-speed automatic when the need for speed moves you. Raising/lowering the convertible top is a two step process -- first, open the trunk a make sure the luggage cover is lowered; this is the large clamshell, that, after lowering, shows you how much trunk space is left after the hard top is lowered. Make sure both sides of the clamshell engage into the trunk sills. Second, with the ignition on and the vehicle in park, there is a button just to the right of the parking brake on the center console. Pull toward the back of the car to lower the top, forward to put the top back up. For more details, turn to page 240 of the car manual. Please use premium unleaded gasoline when refilling the vehicle, here in Arizona it has a rating of 91.
