When driving
RX350/270_EE
CAUTION
●Moving the shift lever to N while the vehicle is moving will disengage the engine
from the transmission. Engine braking is not available when N is selected.
●During normal driving, do not turn off the engine. Turning the engine off while
driving will not cause loss of steering or braking control, but the power assist to
these systems will be lost. This will make it more difficult to steer and brake, so you
should pull over and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop
the vehicle in the normal way: →P. 6 0 3
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (→P. 1 8 7 )
●When stopped on an incline, use the brake pedal and parking brake to prevent
the vehicle from rolling backward or forward, causing an accident.
●Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents, resulting
in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their body are not
outside the vehicle, as this may result in death or serious injury.
●On vehicles with an electronically modulated air suspension, if you drive through
water, such as when crossing shallow streams, first check the depth of the water
and the firmness of the river bed. Put the vehicle in “HI” (high) mode with the
height selector switch and then turn off the electronically modulated air suspen-
sion by pressing the height control off switch. Drive your vehicle at 30 km/h (19
mph) or lower.

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Lexus suspension (lowered suspension, etc.) is installed.
In addition to the examples above, there are instances in which, because of their
shapes, signs and other objects may be judged by a sensor to be closer than they
are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your
vehicle
■If a message is displayed

■Customization
Settings (e.g. buzzer volume) can be changed.

2-4. Using other driving systems
RX350/270_EELuggage compartment
Higher
Pressing this switch while the vehi-
cle is in luggage mode changes the
vehicle height to that of “N” mode.
Lower
Pressing this switch while the vehi-
cle is in “N” mode changes the
vehicle height to that of luggage
mode, not “LO” mode.
■Electronically modulated air suspension indicator
The indicator for the selected
mode will come on.
The indicator will flash while the
vehicle height is being changed to
the height of the selected mode.
Disabling the height control
Press the height control off switch
while the vehicle is stopped. A
message will appear on the multi-
information display, and vehicle
height will be fixed in the current
mode.
When vehicle speed exceeds 30
km/h (19 mph), the electronically
modulated air suspension is re-
enabled automatically.

2-4. Using other driving systems
RX350/270_EE
■When luggage mode is selected
If the vehicle begins to move while still in luggage mode, the vehicle will automati-
cally change to “N” mode once speed exceeds 8 km/h (5 mph). Even if vehicle
speed is reduced below 8 km/h (5 mph), the vehicle height will not automatically
return to luggage mode.
■Operating sound of the air suspension
When the vehicle height is lowered, such as when entering and loading the vehicle,
or when the height selector switch is operated, the sound of the compressor oper-
ating or the mode changing may be heard. This does not indicate a malfunction.
■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.
■Vehicle height mode change time
●If the height control is operated continuously to lower the vehicle, the suspen-
sion air tank may become full, causing operation of the vehicle height lowering
control to become slow.
●To protect the compressor, the system will only raise the vehicle for a total of
100 consecutive seconds. If it takes longer than this to reach the selected
height, operation may be suspended shortly and then restart. However, it may
not be possible to change the vehicle's height mode at this time.
■The electronically modulated air suspension will not operate when
The vehicle height control may not be able to change modes when the vehicle runs
over a high curb or other rugged surfaces where the suspension is stretched.
