When HI mode is selected
■
The vehicle height will change to N mode when driving at the speeds of 50 km/h (31
mph).
Even if vehicle speed is then reduced to under 50 km/h (31 mph), height will not return
to HI mode.

The vehicle height will change to N mode when vehicle speed exceeds 12 km/h (7 mph).

LO mode.
Automatic leveling function
■
Regardless of the number of occupants and the luggage load, vehicle height in any mode
is always adjusted to a fixed height by the automatic leveling function.
The rear height control air suspension will not operate in the following cases:
■
The underbody of the vehicle is touching the surface of the road.
●
The area around the suspension is covered with ice.
●
Even if you hear an operating noise
■
This does not indicate a problem in the rear height control air suspension.
Parking and stopping tips
■
If you immediately stop the engine after off-road driving, or park the vehicle for a long
●
time, the vehicle height may gradually lower. When parking, make sure there is nothing
under the vehicle that may come in contact with the underbody. The vehicle will return
to the set height when the engine is started.
The vehicle height may change as the temperature changes when the engine is
●
stopped. The vehicle will return to the set height when the engine is started.
When lowering the vehicle
■
In order to prevent the vehicle height from rising as occupants leave the vehicle, lowering
control will occur for a short while after the engine has been stopped.
The rear height control air suspension failure warning
■
If a malfunction occurs in the rear height control air suspension, N mode is automati-
●
cally selected. However, the system may not switch to N mode depending on the loca-
tion of the malfunction.
The "CHECK AIR SUSPENSION SYSTEM" is displayed on the multi-information dis-
●
play, and the rear height control air suspension cannot be activated until the malfunc-
tion is corrected.
Stop the engine and start it again. If the warning message turns off, the system is operat-
ing correctly. If the warning message continues to be displayed, have your vehicle
inspected by your Lexus dealer as soon as possible.
