interior lights will turn on.
The Panic Alarm will stay on for three minutes unless you

or drive the vehicle at a speed of 15 mph (24 km/h) or
greater.
NOTE:
• The interior lights will turn off if you place the ignition inthe ACC or ON/RUN position while the Panic Alarm is
activated. However, the exterior lights and horn will
remain on.
• You may need to be less than 35 ft (11 m) from the vehicle when using the key fob to turn off the Panic Alarm due to
the radio frequency noises emitted by the system.
Air Suspension (Remote Lowering Of The Vehicle) — If
Equipped For easy entry and loading, your vehicle can be
lowered by pushing the key fob air suspension
lowering button two times. When key fob lowering is requested, the vehicle will send a series of chirps and flashes
to alert the customer that the operation has begun and will
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.

Enter-N-Go system from starting the vehicle.
NOTE:
Refer to "Starting The Engine" in "Starting And Operating"
for further information.
• Do not leave the key fob in or near the vehicle, or in a
location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless
Enter-N-Go in the ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
