Electrical Load Reduction Actions — If Equipped
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or
the vehicle battery conditions are deteriorating, electrical
load reduction actions will take place to extend the driving
time and distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical loads.

vehicle height by the push of a button.
1 — Up Button
2 — Down Button
3 — Entry/Exit Mode Indicator (Customer selectable)
4 — Normal Ride Height Indicator (Customer selectable)
5 — Off-Road 1 Indicator (Customer selectable)
6 — Off-Road 2 Indicator (Customer selectable)
NOTE:The vehicle will automatically enter Aero Mode
when the vehicle speed remains between 62 mph (100 km/h)
and 66 mph (106 km/h) for greater than 20 seconds or if the
vehicle speed exceeds 66 mph (106 km/h).
• Normal Ride Height (NRH) – This is the standard
position of the suspension and is meant for normal
driving.
• Off-Road 1 (OR1) (Raises the vehicle approximately 1
in [26 mm]) – This position should be the primary
position for all off-road driving until Off Road 2 (OR2) is
needed. A smoother and more comfortable ride will
result. To enter OR1, push the “Up” button once from
the NRH position while the vehicle speed is below
35 mph (56 km/h). When in the OR1 position, if the
vehicle speed remains between 40 mph (64 km/h) and
50 mph (80 km/h) for greater than 20 seconds or if the
vehicle speed exceeds 50 mph (80 km/h), the vehicle
will be automatically lowered to NRH. Off-Road 1 may
not be available due to vehicle payload, an instrument
cluster message will be displayed when this occurs.
Refer to “Instrument Cluster Display” in “Understand-
ing Your Instrument Panel” for further information.

once while in Entry/Exit or drive the vehicle over
15 mph (24 km/h). Entry/Exit mode may not be avail-
able due to vehicle payload, an instrument cluster
message will be displayed when this occurs. Refer to
“Instrument Cluster Display” in “Understanding Your
Instrument Panel” for further information.
NOTE: Entry/Exit mode may be achieved using your key
fob for easier entry/loading. Refer to “A Word About Your
Keys” in “Things To Know Before Starting Your Vehicle”
for further information.
CAUTION!
When in ENTRY/EXIT setting, be aware of your sur-
roundings, you may not have the clearance required for
certain areas and vehicle damage may occur.
The system requires that the ignition be in ON/RUN
position or the engine running for all user requested
changes. When lowering the vehicle all of the doors, must
be closed. If a door is opened at any time while the vehicle
is lowering the change will not be completed until the open
door(s) is closed. This system uses a lifting and lowering pattern which
keeps the headlights from incorrectly shining into oncom-
ing traffic. When raising the vehicle, the rear of the vehicle
will move up first and then the front. When lowering the
vehicle, the front will move down first and then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling to
be disabled. Refer to “Instrument Cluster Display” in
“Understanding Your Instrument Panel” for further infor-
mation.
NOTE:
If equipped with a touch screen radio all enabling/
disabling of air suspension features must be done through
the radio. Refer to “Uconnect Settings” in “Understanding
Your Instrument Panel” for further information.

automatically. Refer to “Instrument Cluster Display” in
“Understanding Your Instrument Panel” for further infor-
mation.
NOTE:This mode is intended to be enabled with engine

loaded, battery charge low, etc.). Load leveling will auto-
matically resume as soon as system operation requirements
are met. See your authorized dealer if system does not
resume.
