Cherokee adds stop-start, safety

by David Zatz on

Just one year old, the 2015 Jeep Cherokee has added a large number of optional features. First is the engine stop-start system (ESS) which Allpar predicted would arrive on the 3.2 V6 only.  It shuts off the engine, while leaving climate control and other key systems on at a stop; as we predicted, the engine restarts automatically when the driver releases the brake. (See our test of a similarly equipped BMW.)

Vehicles with stop-start systems have upgraded starters and associated equipment; Jeep has a longer-durability starter, in a stronger case, with stronger teeth, and a more robust solenoid. It was tested to more than two and a half times as many starts as a normal unit (over 300,000 cycles). A hefty 700-amp AGM battery is included.

Stop-start is only activated if there is enough voltage available for an easy restart, if the driver has not disabled it, and if certain other conditions are met. The system should be available on the Chrysler 200 as well.

The 2.4 liter engine is now certified as a Partial Zero Emission Engine (PZEV) in the 14 states that have adopted California clean air rules; to achieve this, engineers revised the fuel tank, fuel filler neck,  air cleaner, engine downpipe, vapor purge canister, and fuel cap.

A backup camera and automatic headlamps are now standard on Latitude and Trailhawk. Other new 2015 Jeep Cherokee features are:

  • Low-speed crash mitigation added to the forward collision warning
  • SafetyTec Group is now optional on Latitude, Limited and Trailhawk models; it includes blind spot monitoring, rear cross path detection, rear park assist, and signal mirrors.
  • A Ventilated/Memory Seat Group package is optional on Trailhawk (with the Leather Interior Group).
  • Nepal, a Black / Light Frost interior color, replaces Black/Iceland Gray (“Iceland”) on cloth interiors for Sport and Latitude and on leather interior for the Limited
  • New cloth insert fabric on Latitude seats
  • Tonneau Cover is a standalone option for all models
