The air suspension system provides full time load leveling capability along with the benefit of being able to adjust vehicle height by the push of a switch.

Air Suspension Switch

1 — Off-Road 2 Indicator (Customer Selectable) 2 — Off-Road 1 Indicator (Customer Selectable)

3 — Normal Ride Height Indicator (Customer Selectable) 4 — Aero Mode Indicator (Customer Selectable)

5 — Entry/Exit Mode Indicator (Customer Selectable) 6 — Height Selector

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 posi- tion of the suspension and is meant for normal driving.

Off-Road 1 (OR1) (Raises the vehicle approximately 1 inch (26 mm)) – This position should be the primary posi- tion for all off-road driving until Off-Road 2 (OR2) is

needed. A smoother and more comfortable ride will result. 5

To enter OR1, push the height selector switch up 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 “Getting To Know Your Instrument Panel” for further information.

Off-Road 2 (OR2) (Raises the vehicle approximately 2 inches (51 mm)) – This position is intended for off-roading use only where maximum ground clearance is required. To enter OR2, push the height selector switch up twice from the NRH position or once from the OR1 position while vehicle speed is below 20 mph (32 km/h). While in OR2, if the vehicle speed exceeds 25 mph (40 km/h) the vehicle height will be automatically lowered to OR1. Off-Road 2 may not be available due to vehicle payload, an instrument cluster message will be displayed when this occurs. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.

Aero Mode (Lowers the vehicle approximately

0.6 inch [15 mm]) – This position provides improved aerodynamics by lowering the vehicle. 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). The vehicle will

return to NRH from Aero Mode if the vehicle speed remains between 30 mph (48 km/h) and 35 mph (56 km/h) for greater than 20 seconds or if the vehicle speed falls below 30 mph (48 km/h).

NOTE:

Speed thresholds for raising the vehicle only apply if Auto- matic Aero Mode is enabled.

To enter Aero Mode manually push the height selector switch down once from NRH at any vehicle speed. To return to NRH push the height selector switch up once while vehicle speed is less than 56 mph (90 km/h).

NOTE:

Automatic Aero Mode may be disabled through vehicle settings in the instrument cluster display or through your Uconnect Radio if equipped. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” or “Uconnect Settings” in “Multimedia” for further informa- tion.

Entry/Exit Mode (Lowers the vehicle approximately 2 inches (51 mm)) – This position lowers the vehicle for easier passenger entry and exit as well as lowering the rear of the vehicle for easier loading and unloading of cargo. To enter Entry/Exit Mode, push the height selector switch down once from the NRH while the vehicle speed is below

33 mph (53 km/h). Once the vehicle speed goes below 15 mph (24 km/h) the vehicle height will begin to lower. If the vehicle speed remains between 15 mph (24 km/h) and 25 mph (40 km/h) for greater than 60 seconds, or the vehicle speed exceeds 25 mph (40 km/h) the Entry/Exit change will be cancelled. To return to Normal Height Mode, push the height selector switch up once while in Entry/Exit or drive the vehicle over 15 mph (24 km/h). Entry/Exit mode may not be available due to vehicle payload, an instrument cluster message will be displayed when this occurs. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.

NOTE:

Entry/Exit mode may be achieved using your key fob for easier entry/loading. Refer to “Keys” in “Getting To Know Your Vehicle” for further information.

The system requires that the ignition be in the 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 oncoming 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. 5

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 “Getting To Know 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 “Multimedia” for further information.

The Air Suspension system has multiple modes to protect the system in unique situations:

Automatic AERO Mode

To improve aerodynamics, the air suspension system has a feature which will put the vehicle into AERO height auto- matically. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.

Automatic Aero Mode may be disabled through vehicle settings in the instrument cluster display or through your Uconnect Radio if equipped. Refer to “Instrument Cluster

Display” in “Getting To Know Your Instrument Panel” or “Uconnect Settings” in “Multimedia” 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 suspension system has a feature which allows the automatic leveling to be disabled. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” or “Uconnect Settings” in “Multi- media” if equipped with a touch screen radio 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 road, 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 Instrument Panel” or “Uconnect Settings” in “Multimedia” if equipped with a touch screen radio 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” or “Uconnect Settings” in “Multimedia” if equipped with a touch screen radio 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 over- loaded, 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.

When the appropriate conditions exist, a message will appear in the instrument cluster display. Refer to “Instru- ment Cluster Display” in “Getting To Know Your Instru- ment Panel” for further information.

An audible chime will be heard whenever a system error has been detected.

See an authorized dealer for system service if normal opera- tion does not resume.

Air Suspension Switch

1 — Off-Road 2 Indicator (Customer selectable) 2 — Off-Road 1 Indicator (Customer selectable)

3 — Normal Ride Height Indicator (Customer selectable) 4 — Aero Mode Indicator (Customer Selectable)

5 — Entry/Exit Mode Indicator (Customer selectable) 6 — Height Selector

The indicator lamps 1 through 5 will illuminate to show the current position of the vehicle. Flashing indicator lamps will show a position which the system is working to achieve. When raising, if multiple indicator lamps are flashing, the highest flashing indicator lamp is the position the system is working to achieve. When lowering, if multiple indicators are flashing, the lowest solid indicator lamp is the position the system is working to achieve.

Pushing the height selector up once will move the suspen- sion one position higher from the current position, assuming all conditions are met (i.e. key in ON/RUN position, engine running, speed below threshold, etc). The height selector switch can be pushed up multiple times, each push will raise the requested level by one position up to a maximum posi- tion of OR2 or the highest position allowed based on current conditions (i.e. vehicle speed, etc).

Pushing the height selector down once will move the suspen- sion one position lower from the current level, assuming all conditions are met (i.e. key in ON/RUN position, engine running, doors closed, speed below threshold, etc). The height selector switch can be pushed down multiple times, each push will lower the requested level by one position down to a minimum of Entry/Exit Mode or the lowest posi- tion allowed based on current conditions (i.e. vehicle speed, etc.)

Automatic height changes will occur based on vehicle speed and the current vehicle height. The indicator lamps and instrument cluster display messages will operate the same for automatic changes and user requested changes.

Off-Road 2 (OR2) – Indicator lamps 5, 4, 3, 2 and 1 will be illuminated when the vehicle is in OR2.

Off-Road 1 (OR1) – Indicator lamps 5, 4, 3 and 2 will be illuminated when the vehicle is in OR1.

Normal Ride Height (NRH) – Indicator lamps 5, 4 and 3 will be illuminated when the vehicle is in this position.
