Lexus parking assist monitor∗
The parking assist monitor assists with
the following 2 backing-up operations:
• Perpendicular parking (parking in a garage, etc.)
• Parallel parking (parking at the side of the road, etc.)
The screen illustrations used in this text ar e intended as examples, and may differ from
the image that is actually displayed on the screen.
The rear view image is displayed when
the shift position is in R and the engine
switch is in IGNITION ON mode.
The parking assist monitor system will
be deactivated when the shift lever is in
any position other than R.
When the shift lever is shifted to the R
position and any mode button (such as
“SETUP”) is pressed, the parking assist
monitor is canceled, and the screen is
switched to the mode of the button that
was pressed.
∗: If equipped
The parking assist monitor assists the driver by displaying an image of the view
behind the vehicle while backing up, for example while parking.

■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 mod e .
■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 no t switch to N mode depending on the loca-
tion of the malfunction.
●The warning message is displayed on the mult i-information display, and the rear height
control air suspension cannot 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.

■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

●When jacking up the vehicle, installing tire chains or tying the vehicle with chains/
wires for transportation via flatbed truck, turn off the rear height control air suspen-
sion and stop the engine.
●When the vehicle must be towed or disconnecting a trailer, put the vehicle height in N

●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 w ill become higher when in the mode, the
vehicle may become unstable when turning abruptly, resulting in an accident.
●Do not select HI mode when loading cargo on the roof luggage carrier.
