With alloy wheels, body-color door handles, chromed window surrounds and (heated) side mirrors, and a more attractive grille with silver insert bars, the SLE is less rudimentary in its appearance than the Pro. The biggest changes take place inside, though, because this model introduces the large 13.4-inch touchscreen interface with Google built-in capability along with a 12.3-inch digital gauge cluster. The new infotainment system provides seamless access to Google Maps, Google Assistant, and Google Play. A ten-way power-adjustable driver’s seat, a compass, floor carpeting, dual-zone climate control, cloth upholstery, heated outboard front seats, a heated steering wheel, keyless entry and start, a heated and tilting/telescoping steering wheel, remote start, and cruise control are other welcome additions at this level.
