Approximately 150 cm (4.9 ft.)
Approximately 50 cm (1.6 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.

• The shift lever is in a position other than P.
• The vehicle speed is less than about 10 km/h (6 mph).
●Front center sensors:
• The “ENGINE START STOP” switch is in IGNITION ON mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 10 km/h (6 mph).
●Rear corner and center sensors:

CAUTION
■The electronically modulated air suspension must be turned off when
The electronically modulated air suspension must be turned off in the following situ-
ations as vehicle height may change due to the automatic leveling function, and, you
may catch part of your body in the vehicle and cause an accident, resulting in death
or serious injury.
●Any of the wheels is stuck in a ditch.
●It is necessary to jack up the vehicle.
●It is necessary to tow the vehicle with part of it lifted.
●When connecting/disconnecting a trailer
For safety, stop the engine if necessary.
■“HI” mode
●“HI” mode should only be used when driving 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 turning abruptly and cause
an accident, resulting in death or serious injury.
●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 turning abruptly, and cause an accident,
resulting in death or serious injury.

Utility vehicle precautions
Off-road vehicle feature
●Specific design characteristics give it a higher center of gravity than
ordinary passenger cars. This vehicle design feature causes this type of
vehicle to be more likely to rollover. And, utility vehicles have a signifi-
cantly higher rollover rate than other types of vehicles.
●An advantage of the higher ground clearance is a better view of the
road allowing you to anticipate problems.
●It is not designed for cornering at the same speeds as ordinary passen-
ger cars any more than low-slung sports cars designed to perform sat-
isfactorily under off-road conditions. Therefore, sharp turns at
excessive speeds may cause rollover.
This vehicle belongs to the utility vehicle class, which has higher
ground clearance and narrower tread in relation to the height of its
center of gravity to make it capable of performing in a wide variety of
off-road applications.

Off-road driving
When driving your vehicle off-road, please observe the following precau-
tions to ensure your driving enjoyment and to help prevent the closure of
areas to off-road vehicles.
●Drive your vehicle only in areas where off-road vehicles are permitted
to travel.
●Respect private property. Get owner’s permission before entering pri-
vate property.
●Do not enter areas that are closed. Honor gates, barriers and signs
that restrict travel.
CAUTION
■Off-road vehicle precautions
Always observe the following precautions to minimize the risk of death or serious
injury or damage to your vehicle:
●In a rollover crash, an unbelted person is significantly more likely to die than a
person wearing a seat belt. Therefore, the driver and all passengers should fasten
their seat belts whenever the vehicle is moving.
●Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or vehicle roll-
over causing death or serious injury.
●Loading cargo on the roof luggage carrier will make the center of the vehicle
gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or
abrupt maneuvers, otherwise it may result in loss of control or vehicle rollover
due to failure to operate this vehicle correctly.
●Always slow down in gusty crosswinds. Because of its profile and higher center of
gravity, your vehicle is more sensitive to side winds than an ordinary passenger
car. Slowing down will allow you to have better control.
●Do not drive horizontally across steep slopes. Driving straight up or straight down
is preferred. Your vehicle (or any similar off-road vehicle) can tip over sideways
much more easily than forward or backward.

CAUTION
■Roof luggage carrier precautions (if equipped)
To use the roof rails as a roof luggage carrier, you must fit the roof rails with two or
more genuine Lexus cross rails or their equivalent.
When you load cargo on the roof luggage carrier, observe the following:
●Before driving, make sure the cargo is securely fastened on the roof luggage car-
rier.
●Loading cargo on the roof luggage carrier will make the center of gravity of the
vehicle higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or
abrupt maneuvers, otherwise the result may be a loss of control or vehicle roll-
over due to failure to operate this vehicle correctly and result in death or serious
injury.
●If driving for long distances, on rough roads, or at high speeds, stop the vehicle
now and then during the trip to make sure the cargo remains in its place.
●Do not exceed 75 kg (165 lb.) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo
Be careful not to scratch the surface of the moon roof.
●Place the cargo so that its weight is distrib-
uted evenly between the front and rear
axles.
●If loading long or wide cargo, never exceed
the vehicle’s overall length or width.
