In case the ignition switch does not change with the push of
a button, the key fob may have a low or fully depleted
battery. A low key fob battery can be verified by referring to
the instrument cluster, which will display directions to
follow.
NOTE:
A low key fob battery condition may be indicated by a
message in the instrument cluster display, or by the LED
light on the key fob. If the LED key fob light no longer illu-
minates from key fob button pushes, then the key fob battery
requires replacement.
In a situation where the battery is low or fully depleted, a
back up method can be used to operate the ignition switch.
Put the nose side of the key fob (side opposite of the emer-
gency key) against the START/STOP ignition button and
push to operate the ignition switch.

acknowledge the unlock signal. The illuminated entry
system will also turn on. NOTE:
The instrument cluster display or Uconnect Settings are
setup for driver door first, otherwise this will unlock all
doors.
To Lock The Doors And Tailgate

continue these alerts until it successfully lowers.
The following conditions must be met for the vehicle to
lower remotely:
• The vehicle must not already be in Entry/Exit (Park) ride
height.
• The vehicle battery must be fully charged.
• All doors must be closed.
• The key fob must be out of the vehicle.
NOTE:
Ensure the vehicle is clear of all objects, pets, and people
prior to remote lowering.
Canceling Remote Lowering
Vehicle lowering can be cancelled at anytime. When vehicle
lowering is cancelled, the vehicle will raise up to the next
defined level and lock out the remote lowering feature until
the ignition has been cycled ON/OFF.
