■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.
• 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.
• The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected ini-
tially, but as they draw closer, they may cease to be detected.
• A towing hitch is mounted to the vehicle.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• When attaching a two-way radio antenna.
• When a towing eyelet is mounted on your vehicle.
• When the bumper is damaged.
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.

When driving
■Automatic leveling function
Regardless of the number of occupants or the luggage load, vehicle height
in any mode is always adjusted to a fixed height by the automatic leveling
function.
■ When HI mode is selected
The vehicle height will change to N mode when driving at the speeds of 18
mph (30 km/h).
■ When LO mode is selected
●The vehicle height will change to N mode when vehicle speed exceeds 7
mph (12 km/h).
● This mode allows for easy access to the vehicle (getting in and out) and
easy loading and unloading.
■ The electronically modulated air suspen sion will not operate in the fol-
lowing cases:
● The underbody of the vehicle is touching the surface of the road.
● The area around the suspension is covered with ice.
The height control indicators will blink, turn off and then turn on continuously
to indicate that the electronically modulated air suspension is not opera-
tional.
To re-enable operation, turn off the engine and then restart it.
■ Even if you hear an operating noise
This does not indicate a problem in the electronically modulated air suspen-
sion.
■ If there is a problem somewhere in the electronically modulated air
suspension
The height control MAN. indicator will behave as follows:
●The indicator will not come on when the engine switch is turned on.
● The indicator will blink.
Although the vehicle may be driven, have the vehicle inspected by your Toy-
ota dealer.

236 2-4. Using other driving systems
CAUTION
■The electronically modulated air susp ension must be turned off in the
following circumstances:
Otherwise, the automatic leveling function may cause the vehicle’s height to
change, and you may catch part of your body in the vehicle, resulting in an
unexpected accident:
● When driving through water such as shallow streams (Put the vehicle
height in HI mode and turn off the electronically modulated air suspension.
Drive at 18 mph [30 km/h] or slower.)
● When jacking up the vehicle, installing tire chains or tying the vehicle with
chains/wires for transportation via flat bed truck (Turn the system to the
manual mode and stop the engine.)
● When the vehicle must be towed (Put the vehicle height in N mode and
turn the system to the manual mode.)
● When the vehicle gets stuck (Turn the system to the manual mode.)
● When disconnecting a trailer (Put the vehicle height in LO mode and turn
the system to the manual mode.)
■ Selecting the correct height mode
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the vehicle, as well as dan-
gerous handling characteristics, which may lead to fatal or injury accidents.
●Before you lower the vehicle’s height, check under the vehicle to make
sure that no one is there.
● 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, resulting
in an accident.
● Do not select HI mode when you load 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, resulting
in an accident.

When driving
If you cannot find any problems, the speed at which trailer swaying occu\
rred
is beyond the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the
towing vehicle-trailer increases as speed increases.
CAUTION
■
Trailer towing precautions
●To tow a trailer safely, use extreme care and drive the vehicle in accor-
dance with the trailer’s characteristics and operating conditions. Failure to
do so could cause an accident resulting in death or serious injury. Vehicle
stability and braking performance are affe cted by trailer stability, brake set-
ting and performance, and the hitch. Y our vehicle will handle differently
when towing a trailer.
● Vehicles with electronically modulated air suspension: Set the vehicle
height to the LO mode and turn off the rear height control air suspension
when you connect a trailer, otherwise the vehicle height may change due
to the automatic leveling function, and you may catch part of your body in
the vehicle, resulting in an accident.
■ To avoid accident or injury
●Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway control device
with sufficient capacity is required.
● If the gross trailer weight is over 5000 lb. (2268 kg), a weight distributing
hitch with sufficient capacity is required.
● Adjust the tongue weight within the appropriate range. Place heavier loads
as close to the trailer axle as possible.
● Do not exceed 65 mph (104 km/h), the posted towing speed limit or the
speed limit for your trailer as set forth in your trailer owner’s manual,
whichever is lowest. Slow down sufficiently before making a turn, in cross-
winds, on wet or slippery surface, etc. to help avoid an accident. If you
experience a vehicle-trailer instabilit y from reducing a certain speed, slow
down and make sure you keep your vehicle speed under the speed of
which you experience the instability.
● Do not make jerky, abrupt or sharp turns.
