CAUTION
■Caution when using the intuitive parking assist
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● Do not attach any accessories within the sensor range.
NOTICE
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

Electronically modulated air suspension (if equipped)
Selecting vehicle heightHigher
Lower
Vehicle height can be adjusted
only when the engine is running.
The indicator stops blinking, and
comes on continuously to indi-
cate that the mode shift is com-
pleted.
■ Height modes
●N mode (normal mode): For ordinary driving
Normal height
● HI mode (high mode): For driving on bumpy roads
1.2 in. (30 mm) higher than the normal height
The HI mode is unavailable w hen the vehicle’s speed exceeds
18 mph (30 km/h).
The electronically modulated air suspension allows the driver to
control the vehicle’s height in orde r to adjust for driving conditions.
Select the desired height with the height control switch.

When driving
When the vehicle’s speed exceed s 18 mph (30 km/h), the height
will be adjusted to the norm al height automatically.
● LO mode (low mode): For the ease of egress/ingress and load-
ing luggage
1.2 in. (30 mm) lower than the normal height
The LO mode is unavailable when the vehicle’s speed exceeds
8 mph (12 km/h).
When the vehicles speed exceeds 8 mph (12 km/h), the height
will be adjusted to the norm al height automatically.
Disabling the height control
When the height control mode
select switch is pressed, the
vehicle height is fixed at the cur-
rent height.
The height can be adjusted by
pressing the height control mode
select switch.
When the vehicle’s speed
exceeds 18 mph (30 km/h), the
height will be adjusted to the nor-
mal height automatically.

■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 1\
8
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 susp ension 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 indicators will blink, turn off and then turn on continuously to indicate
that the electronically modulated air suspension is not operational.
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.

When driving
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, 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.
● The HI mode should be used for off-road driving conditions.
As the vehicle’s center of gravity is higher in this setting, the vehicle may
become unstable when turning abruptly.
● Do not select HI mode when you load cargo on the roof luggage carrier.
This may result in a loss of control or vehicle rollover.

206 2-4. Using other driving systems
NOTICE
■Be careful in any place where overhead space is limited.
When changing to a higher mode or after unloading, the vehicle height will
rise. 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.
■ Do not change the vehicle height frequently.
The compressor might overheat and cause the operation to stop.
■ When on the extremely uneven roads with rocks
Sometimes the vehicle height is not adjusted because it is judged as uneven
road driving.

■Driving mode
●Sport mode is suitable for winding mountain road driving, high speed
driving or towing a trailer.
● Normal mode is suitable for ordinary driving.
Adaptive variable suspension system controls the suspension
according to the road and driving conditions. Selecting an optimum
