A Word About Your Keys; Keyless Push Button Ignition - Jeep Grand Cherokee 2016 Owner's Manual

14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

A WORD ABOUT YOUR KEYS

Your vehicle uses a keyless ignition system. This system
consists of a Key Fob with Remote Keyless Entry (RKE)
transmitter and a Keyless Push Button Ignition.

Keyless Push Button Ignition

This feature allows the driver to operate the ignition
switch with the push of a button, as long as the Remote
Keyless Entry (RKE) transmitter is in the passenger
compartment.
The Keyless Push Button Ignition has four operating
positions; three of which are labeled and will illuminate
when in position. The three positions are OFF, ACC, and
ON/RUN. The fourth position is START, during start
RUN will illuminate.
NOTE: In case the ignition switch does not change with
the push of a button, the RKE transmitter (Key Fob) may
have a low or dead battery. In this situation, a back up
method can be used to operate the ignition switch. Put
the nose side (side opposite of the emergency key) of the
Key Fob against the ENGINE START/STOP button and
push to operate the ignition switch.
