The Quadra-Lift Air Suspension system provides full-time load leveling capability along with the benefit of vehicle height adjustment by a toggle switch. The vehicle will automatically raise and lower the ride height to adapt to the appropriate driving conditions. At higher speeds, the vehicle will lower to an aerodynamic ride height and when operating in off-road modes (if equipped), the vehicle will raise the ride height accordingly. The buttons near the terrain switch in the center console area can be used to set preferred ride height to match the appropriate conditions.

• 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 1.2 inches [30 mm]) – This is the primary position for all off-road driving until OR2 is needed. A smoother and more comfortable ride will result. Push the toggle switch forward once from the NRH position while the vehicle speed is below 38 mph (61 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 DRIVING TIPS. OR1 is unavailable on 4x2 air suspension vehicles.

• Off-Road 2 (OR2) (Raises the vehicle approximately 2.0 inches [51 mm]) – This position is intended for off-roading use only where maximum ground clearance is required. To enter OR2, push the toggle switch forward 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 DRIVING TIPS. OR2 is unavailable on 4x2 air suspension vehicles.

• Aero Height (Lowers the vehicle approximately -0.6 inches [-15 mm]) – This position provides improved aerodynamics by lowering the vehicle. The vehicle will automatically enter Aero Height 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 Default Ride Height from Aero Height 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). The vehicle will enter Aero Height, regardless of vehicle speed if the vehicle is in “SPORT” mode.

• Entry/Exit Height (Lowers the vehicle approximately -1.6 inches [-40 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 Height, push the toggle switch down twice from NRH while the vehicle speed is below 6 mph (10 km/h). To exit Entry/Exit Height, push the UP button once while in Entry/Exit Height or drive the vehicle over 4 mph (6 km/h).

  Note:

  Automatic lowering of the vehicle into Entry/Exit Height can be enabled through the Uconnect Touchscreen Radio. If this feature is enabled, the vehicle will only lower if the gear selector is in PARK, the terrain switch is in AUTO, the transfer case is in AUTO and the vehicle level is either in Normal or Aero Height. The vehicle will not automatically lower if the air suspension level is in OR2 or OR1. When towing, the automatic Entry/Exit feature may be disabled through the Uconnect Touchscreen Radio to prevent vehicle and trailer movement when gear selector is moved to PARK.

The Selec-Terrain system will automatically change the vehicle to the proper height based on the position of the Selec-Terrain switch. The height can be changed from the default Selec-Terrain setting by normal use of the air suspension buttons SELEC-TERRAIN — IF EQUIPPED.

The system requires that the engine be running for all changes. When lowering the vehicle all of the doors, including the liftgate, 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/are closed.

The Quadra-Lift Air Suspension 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.

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 Quadra-Lift Air Suspension system has a feature which allows the automatic leveling to be disabled UCONNECT SETTINGS.

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

Tire/Jack Mode

To assist with changing a spare tire, the air suspension system has a feature which allows the automatic leveling to be disabled UCONNECT SETTINGS. Tire/Jack mode is used for connecting a trailer with a weight-distributing hitch Weight-Distributing Hitch.

Auto Entry/Exit Mode

To assist in entering and exiting the vehicle, the air suspension system has a feature which automatically lowers the vehicle to Entry/Exit Height UCONNECT SETTINGS.

Transport Mode

To assist with flatbed towing, the air suspension system has a feature which will put the vehicle into Entry/Exit Height and disable the automatic load leveling system UCONNECT SETTINGS.

Suspension Display Messages Mode

The “Suspension Display Messages” setting allows you to only display suspension warnings instead of all suspension messages (i.e., “Normal Height Achieved”) UCONNECT SETTINGS.

Wheel Alignment Mode

Before performing a wheel alignment this mode must be enabled which will move the vehicle to Normal Ride Height and disable the air suspension during the alignment UCONNECT SETTINGS.

If equipped with a Uconnect Touchscreen Radio, all enabling/disabling of air suspension features must be done through the radio UCONNECT SETTINGS.

When the appropriate conditions exist, a message will appear in the instrument cluster INSTRUMENT CLUSTER DISPLAY.

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 while raising, the highest flashing indicator lamp is the position the system is working to achieve. When lowering, if multiple indicators are flashing while lowering the lowest solid indicator lamp is the position the system is working to achieve.

Toggle up once moves the suspension one position higher from the current position, assuming all conditions are met (i.e., engine running, speed below threshold, etc.). Toggle up can be pushed multiple times. Each toggle up will raise the requested level by one position up to a maximum position of OR2 or the highest position allowed based on current conditions (i.e., vehicle speed, etc.).

Toggle down once moves the suspension one position lower from the current level, assuming all conditions are met (i.e., engine running, doors closed, speed below threshold, etc.). Toggle down can be pushed multiple times. Each toggle down will lower the requested level by one position down to a minimum of Park mode or the lowest position 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.
