Air Suspension Modes; Axle Locker System - If; Equipped - RAM 1500 2019 User Manual

Air Suspension Modes

The Air Suspension system has multiple
modes to protect the system in unique situa-
tions:
AERO Mode
To improve aerodynamics, the air suspension
system has a feature which will put the
vehicle into AERO height automatically.
Refer to "Instrument Cluster Display" in
"Getting To Know Your Instrument Panel" in
the Owner's Manual for further information.
NOTE:
This mode is intended to be enabled with
engine running.
Tire Jack Mode
To assist with changing a tire, the air suspen-
sion system has a feature which allows the
automatic leveling to be disabled. Refer to
"Instrument Cluster Display" in "Getting To
Know Your Instrument Panel" in the Owner's
Manual for further information.
NOTE:
This mode is intended to be enabled with
engine running.
Transport Mode
For towing your vehicle with four wheels off
the ground, the air suspension system has a
feature which will put the vehicle into Entry/
Exit height and disable the automatic load
leveling system. Refer to "Instrument Cluster
Display" in "Getting To Know Your Instru-
ment Panel" in the Owner's Manual for
further information.
NOTE:
This mode is intended to be enabled with
engine running.
Wheel Alignment Mode
Before performing a wheel alignment, this
mode must be enabled. Refer to "Instrument
Cluster Display" in "Getting To Know Your
Instrument Panel" in the Owner's Manual for
further information.
NOTE:
This mode is intended to be enabled with
engine running.
Protection Strategy
In order to "protect" the air suspension
system, the vehicle will disable load leveling
as required (suspension overloaded, battery
charge low, etc.). Load leveling will automat-
ically resume as soon as system operation
requirements are met. See your authorized
dealer if system does not resume.
NOTE:
If towing with air suspension refer to "Trailer
Towing" in "Starting And Operating" for
further information.
AXLE LOCKER SYSTEM — IF

EQUIPPED

This vehicle is equipped with an electroni-
cally locking rear differential. This differen-
tial, when engaged, mechanically lock
together the axle shafts forcing the wheels to
spin at an equal rate. The locking of the rear
differential should only be engaged during
low-speed, extreme off-road situations where
one wheel is likely to not be in contact with
the ground. It is not recommended to drive
the vehicle with the differentials locked on
pavement due to the reduced ability to turn
and speed limitations.
