- ON-ROAD mode (road traffic) - normal working height of the vehicle
- OFF-ROAD mode (off-road driving) - in this mode, an increased height compared to the road mode is maintained, which provides greater ground clearance, angles of entry, exit and overcoming the ridge.
- ACCESS Mode (landing) - in this mode, a reduced height is maintained compared to the driving mode on the road, which facilitates the boarding and disembarking of passengers.
- CRAWL Mode (driving at reduced speed at ride height) - In this mode, the car can drive at a ride height at a low speed, which is convenient when entering a parking lot with a low roof, etc.
NOTE: Changing the height of the vehicle is not possible if the air suspension control unit receives a signal "the door is open" from the central electrical box (CJB).
An optional TRANSPORTATION·mode is also available (transportation), but it can only be selected using Land Rover approved diagnostic equipment.
An additional function allows you to increase and decrease the height of the car from the outside when it is stationary. For example, this function simplifies the attachment of a trailer. It is activated by the buttons on the remote control when the ignition is off. The remote control can be programmed to perform a number of additional functions. For more information refer to Handles, Locks, Latches and Entry Systems (501-14 Handles, Locks, Latches and Entry Systems)
If the air suspension control unit has determined that the vehicle "sat down" on the bottom, and the wheels have lost traction, the control unit can temporarily increase and / or redistribute the volume of air supplied to the corresponding pneumatic elastic element (elements) to improve road grip. This mode is called extended mode and the driver is informed of its activation by flashing air suspension switch lamps and messages on the information display in the center of the instrument panel.
If the air suspension control module has determined that a height or body tilt correction is preventing the vehicle from moving forward or backward, the air suspension control module will go into a safe state and suspend further changes in suspension height.
When the air suspension control unit detects a malfunction, it reduces system functionality depending on the type and severity of the malfunction. The control unit will also store a fault code that can be read using Land Rover approved diagnostic equipment. In the event of a serious malfunction, the control unit attempts to bring the vehicle into a safe state. The driver is informed of a malfunction by the air suspension indicator, a message in the instrument cluster message center display, and an audible signal from the instrument panel.
In the event of a minor malfunction that does not affect the safe operation of the vehicle, the air suspension control indicator on the instrument panel will light up in yellow; this means that the fault should be rectified as soon as possible. If a more serious malfunction is detected at speeds above 50 km/h, the indicator will glow red and the vehicle should be used with extreme caution until the malfunction is corrected. When the indicator is on, the instrument panel beeps. When the vehicle speed decreases, the indicator color changes to yellow and the horn stops.

Road driving mode
This mode corresponds to the normal height of the car body
Off-road driving mode
The off-road driving mode is activated only if the vehicle speed is less than 40 km/h. The vehicle is raised by 55mm when compared to road mode, which provides greater ground clearance, approach, exit and ridge-climbing angles. If the vehicle speed exceeds 50 km/h, the air suspension control unit automatically lowers the vehicle to a height suitable for road driving. At a speed of 40-45 km/h, a message appears on the message center display prompting the driver to slow down, otherwise the vehicle height will be lowered.
NOTE: Selecting some modes of the Terrain Response system at the lower stage of the transfer case may cause the suspension to automatically switch to off-road mode.
Landing mode
In the entry mode, the height of the vehicle body is reduced by 50 mm to facilitate entry, exit and loading. The seating mode can be selected in advance while the vehicle is in motion. When slowing down, the height of the car will partially decrease; full descent to the landing mode altitude occurs when the speed reaches 8 km/h. If the required speed is not reached within the set time, the air suspension returns to the previously set vehicle height.
Landing mode can be selected at any vehicle speed. When the landing mode is selected, the reaction of the air suspension system depends on the vehicle speed:
- If the speed is above 20 km/h, the air suspension control unit will wait one minute for the vehicle to decelerate. The landing mode lamp and the lowering lamp will flash while the air suspension control module waits for the vehicle to slow down; the road mode lamp will be lit. If the vehicle speed does not decrease sufficiently, the request to enter the landing mode will be canceled after 1 minute.
- If the vehicle speed is below 20 km/h, the air suspension control unit will partially lower the suspension and maintain this height for one minute. When the suspension height is partially lowered by the control unit, the road mode lamp goes out. Landing mode lamp and altitude reduction lamp will be lit. When the partially reduced altitude is reached, the reduced altitude lamp will flash. If the speed does not drop below 8 km/h within one minute, the landing mode request is cancelled.
- If the vehicle speed is below 8 km/h, the suspension immediately lowers to the landing height. Landing mode lamp and altitude reduction lamp will be lit. When the landing mode altitude is reached, the altitude reduction lamp goes out.
The seating height can be selected within 40 seconds after the ignition is turned off, provided that the driver's door has not been opened at this time.
The vehicle automatically rises from landing mode when the speed exceeds 10 km/h. If landing mode was selected from off-road driving mode, the system returns to off-road driving mode when the speed exceeds 10 km/h. In other cases, the system raises the suspension to a height appropriate for road travel.
Landing mode selection directly from off-road driving mode
If the air suspension switch is pressed in off-road mode and then pressed again before the height reduction lamp goes out, the control unit will lower the suspension to the ride height. The control unit will automatically return the suspension to the off-road driving height when the speed exceeds 10 km/h.
Reduced speed mode at ride height
In this mode, the car can move at the landing height. The height of the car is fixed at a level corresponding to the landing mode. This mode can be selected at speeds below 35 km/h. It allows you to increase the clearance from above when driving at low speed in low spaces, such as in parking lots.
When the vehicle speed exceeds 40 km/h, the low driving mode is turned off and the system adjusts the altitude to match the road driving mode.
In this mode, the vehicle can be driven at low speed with the suspension locked at the ride height. This provides more free space above the roof of the car, which is useful, for example, when entering a low garage.
Mode "CRAWL" can be switched on at normal or low body height (appropriate regime "ACCESS") at speeds up to 35 km/h by long pressing the switch down. The Landing Mode and Low Altitude Driving Mode Lamps will light up. When the control unit is in Low Altitude Driving Mode, when the speed exceeds 40 km/h, the road driving height will be set automatically. At a speed of 30-35 km/h, a message appears on the message center display prompting the driver to slow down, otherwise the vehicle height will increase. It is also possible to turn off low altitude driving mode manually by pushing the switch up for 1 second. The low driving mode lamp goes out.
Warnings accompanying automatic height change
If the suspension is in modes "OFF-ROAD", "ACCESS" or "CRAWL", the control unit will automatically change the suspension height if the vehicle speed exceeds the set value.
If the suspension is in off-road or low-level driving mode, the control unit warns the driver that the vehicle speed is approaching the threshold. The instrument cluster beeps, a message is displayed in the instrument cluster message center display, and the road mode lamp and the height increase or decrease lamp flash.
When the vehicle speed decreases, the off-road and low-altitude speed warnings are cancelled.
