Driving
■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 un der 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 un der 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 th e 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”/“C heck air suspension system” is dis-
played on the multi-information display, and the rear height control air suspension can-
not be activated until the malfunction 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.

WARNING
■The rear height control air suspension must be turned off
Be sure to observe the following precautions. Otherwise, the automatic leveling func-
tion may cause vehicle height to change, an
d you may catch part of your body in the
vehicle, resulting in an accident:
●When jacking up the vehicle, installing tire chains or tying the vehicle with chains/
wires for transportation via flatbed truck, tu rn off the rear height control air suspen-
sion and stop the engine.
●When the vehicle must be towed or disconnect ing a trailer, put the vehicle height in N
mode and turn off the rear he ight control air suspension.
●When the vehicle is stuck, turn off the rear height control air suspension.
■Selecting the correct height mode
●HI mode should only be used when drivin g on rough roads, for example when driving
off-road.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turnin g abruptly, resulting in an accident.
●Do not select HI mode when loading cargo on the roof luggage carrier.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turnin g abruptly, resulting in an accident.
●Before lowering vehicle height, check that there is no one under the vehicle.
NOTICE
■Be careful in any place where overhead space is limited
The vehicle height will rise when a higher mode is selected or cargo is unloaded. This
may cause damage to the vehicle.
■Do not select LO mode when driving on bumpy roads
If the underbody of the vehicle touches a rugged road surface, the vehicle may be
damaged.
■Changing vehicle height
Do not change vehicle height frequently.
The compressor may overheat and stop operation.
■When on the extremely uneven roads with rocks
Sometimes the vehicle height is not adjusted because it is judged as uneven road driv-
ing.

Maintenance and care
◆Registering ID codes
Every tire pressure warning valve and transmitter has a unique ID code.
When replacing a tire pressure warning valve and transmitter, it is necessary
to register the ID code.
When registering the ID codes, perform the following procedure.
Park the vehicle in a safe place, wait for approximately 20 minutes, and
then start the engine. ( P. 200)

Then a message will be displayed on
the multi-information display.
When registration is being performed, the tire pressure warning light will blink for
approximately 1 minute then illuminate and “--” will be displayed for the inflation
pressure of each tire on the multi-information display.
Drive at approximately 25 mph (40 km /h) or more for approximately 10 to
30 minutes.
Registration is complete when the tire pressure warning light turns off and the
inflation pressure of each tire is displayed on the multi-information display.
Even if the vehicle is not driven at approxim ately 25 mph (40 km/h) or more, reg-
istration can be completed by driving for a long time. However, if registration does
not complete after driving for 1 hour or more, perform the procedure again from

Maintenance and care
■The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carryi ng out initialization or tire inflation pres-
sure adjustment.
●If you have accidentally turned the engine swit ch off during initialization, it is not neces-
sary to manually restart the in itialization again, as initialization will restart automatically
the next time the engine switch is turned to IGNITION ON mode.
●If you accidentally perform initialization when initialization is not necessary, adjust the
tire inflation pressure to the specified leve l when the tires are cold, and conduct initial-
ization again.
●While the position of each tire is being de termined and the inflation pressures are not
being displayed on the multi-info rmation display, if the inflation pressure of a tire drops,
the tire pressure warning light will come on.
■Warning performance of the tire pressure warning system
The warning of the tire pressu re warning system will change in accordance with the con-
ditions under which it was init ialized. For this reason, the system may give a warning even
if the tire pressure does not reach a low enough level, or if the pressure is higher than the
pressure that was adjusted to when the system was initialized.
■When initialization of the tire pressure warning system has failed
●Do not move the vehicle backward during in itialization. Initialization is started again
from the beginning and it ma y take longer than usual.
●Initialization may take longer to complete if the vehicle is driven on an unpaved road.
When performing initialization, drive on a paved road if possible. Depending on the
driving environment and cond ition of the tires, initialization will be completed in
approximately 10 to 30 minutes.
• If initialization is not comp lete after driving approximately 30 minutes, continue
driving for a while.
• If initialization is not complete after driv ing approximately 1 hour, park the vehicle in
a safe place for approximately 20 minutes. Then drive straight (with occasional left
and right turns) at approximat ely 25 mph (40 km/h) or more
* for approximately 10
to 30 minutes.
If initialization is still not complete, have the vehicle inspected by your Lexus dealer.
*: Except when making a left/right turn
●In the following situations, th e tire inflation pressure will not be recorded and the system
will not operate properly. Perform initialization again.
• If, when attempting to start initialization , the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for ab out 20 minutes after performing initializa-
tion, the tire pressure warning light blinks for approximately 1 minute and then illumi-
nates.

■When registering ID codes
●ID code registration is performed while driving at a vehicle speed of approximately 25
mph (40 km/h) or more.
●Before performing ID code registration, make
sure that no wheels with tire pressure
warning valve and transmitters installed are near the vehicle.
●Initialize the tire pressure warning system after ID code registration. Initialization is dis-
abled if the system was init ialized before registration.
●After ID code registration, the tires are hot by driving. Initialize the tire pressure warn-
ing system after the tires become cold.
●ID codes can be registered by yourself, bu t depending on the driving conditions and
driving environment, registration may take some time to complete.
■Canceling the change wheel set mode
●If turning the engine switch off when in th e change wheel set mode before driving, the
change wheel set mode is canceled.
●After driving when in the ch ange wheel set mode, the change wheel set mode cannot
be canceled. To cancel the mode, perform th e procedure for ID code registration again
and turn the engine switch off before driving.
●If the change wheel set mode is canceled, the ID codes that have already been regis-
tered are communicated. When communication is finished, the tire pressure warning
light will turn off.
■When ID code registration has failed
●Registration may take long time or the ID codes may not be registered in the following
situations.
• When the vehicle is moved ba ckward during registration.
Registration is started again from the beginning and it may take longer than usual.
• When another vehicle is running the side of the vehicle such as in heavy traffic. It may take longer to detect the vehicle’s tire pressure warning valves and transmit-
ters.
• If tire pressure warning valves an d transmitters are in the vehicle.
The ID codes may not be registered.
●When performing registration , drive on a paved road if possible. Depending on the
driving environment and conditio n of the tires, registration will be completed in approx-
imately 10 to 30 minutes.
• If registration is not comple te after driving approximately 30 minutes, continue driv-
ing for a while.
• If registration is not complete after driving approximately 1 hour, park the vehicle in a safe place for approximately 20 minutes. Then drive straight (with occasional left
and right turns) at approximat ely 25 mph (40 km/h) or more
* for approximately 10
to 30 minutes.
If registration is still not complete, have the vehicle inspected by your Lexus dealer.
*: Except when making a left/right turn
●When the tire pressure warning light does not blink slowly 3 times, the ID code will not
be registered and the system will not operate properly. Perform registration again.
