■When HI mode is selected
The vehicle height will change to N mode when driving at the speeds of 18 mph (30
km/h). 
Even if vehicle speed is then reduced to under 18 mph (30 km/h), height will not
return to HI mode.
■When LO mode is selected
The vehicle height will change to N mode when vehicle speed exceeds 7 mph
(12 km/h). 
Even if vehicle speed is then reduced to under 7 mph (12 km/h), height will not
return to 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

a long time, the vehicle height may gradually lower. When parking, make sure
there is nothing under the vehicle that ma y 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 auto-
matically selected. However, the system may not switch to N mode depending
on the location of the malfunction.
●The warning message is displayed on the multi-information display, and the rear
height control air suspension cannot be activated until the malfunction is cor-
rected. 
Stop the engine and start it again. If th e warning message turns off, the system is
operating correctly. If the warning mess age continues to be displayed, have
your vehicle inspected by your Le xus dealer as soon as possible.
CAUTION
■The rear height control air suspension must be turned off when
In the following situations, the automatic leveling function may cause vehicle height
to change, resulting in an unexpected accident:
●When jacking up the vehicle, installing tire chains or tying the vehicle with chains/
wires for transportation via flat bed truck (Turn off the rear height control air sus-
pension and stop the engine.)
●When the vehicle must be towed or disconnecting a trailer (Put the vehicle height

■When the four-wheel drive control switch can be operated
●The “ENGINE START STOP” switch is in IGNITION ON mode.
●The shift lever is in the N position.
●The vehicle is stopped completely.
■The low speed four-wheel drive indicator light
●The indicator light blinks while switching between H4 and L4.
●If the low speed four-wheel drive indicator light continues to blink when you
operate the four-wheel drive control switch to the H4 or L4 position, stop the
vehicle completely, shift the shift lever securely into N and then operate the
switch again.
●If the shift lever is moved before the low speed four-wheel drive indicator turns
on/off, the transfer mode may not be shifted completely. The transfer mode dis-
engages both the front and rear drive shafts from the powertrain and allows the
vehicle to move regardless of the shift position. (At this time, the indicator blinks
and the buzzer sounds.) 
Therefore, the vehicle is free to roll even if the shift lever is in P. You or someone
else could be seriously injured. You must complete the shifting of the transfer
mode and confirm that the indicator light has turned off (H4) or turned on (L4).
●If the engine coolant temperature is too low, the four-wheel drive control system
may not be able to shift. When the engine is warmer operate the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive
system.

■When the center differential lock/unlock switch can be operated
The “ENGINE START STOP” switch is in IGNITION ON mode.
■The center differential lock indicator light
●The indicator light blinks while lockin g/unlocking the center differential.
●If the center differential lock indicator light blinks and the buzzer sounds when
the center differential is locked, stop the slipping or spinning and push the
switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive
system.
■Locking/unlocking the center differential
●When the four-wheel drive control switch is in L4 with the center differential
locked, VSC is automatically turned off. (The center differential lock and VSC
OFF indicator light will come on.)
●If the operation is not completed, the center differential lock indicator blinks. If
the indicator light does not turn off when unlocking the center differential, drive
straight ahead while accelerating or decelerating, or drive in reverse.
●Avoid turning suddenly while the center diff erential is locked. If you do turn sud-
denly, the difference in turning speeds between the front and rear wheels may
have a similar effect to braking, thus making driving difficult.

tem will stop operating, a buzzer will sound, the Crawl Control indicator will turn off
after flashing and the TRAC OFF will be show n on the multi-information display. In
this case, quickly stop the vehicle in a sa fe place and give the actuator adequate
time to cool off. Refrain from using the sy stem until the message goes off. (The vehi-
cle can be driven normally during this time.)
