The Jeep Cherokee (KL) is a Compact crossover SUV manufactured and marketed by the Jeep subdivision of Fiat Chrysler Automobiles. The Cherokee is the first Jeep vehicle to use the Fiat Compact/Compact Wide platform, co-developed by Chrysler and Fiat. The Jeep Cherokee can be equipped with three different four-wheel drive systems: Active Drive I, Active Drive II, and Active Drive Lock. All of these systems come with Jeep's Selec-Terrain traction control system and rear-axle disconnect feature. The rear axle disconnect feature, a first for Compact SUV, disconnects the rear-axle when four-wheel drive is not needed. This lowers parasitic drivetrain load; which improves fuel efficiency.[3]
