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.
■Intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in ON.
• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h).
● Rear corner and rear center sensors:
• The engine switch is in ON.
• The shift lever is in R.

Limitations of the sensors
●The detection areas of the sensors are limited to the areas aro und the vehi-
cle’s front corners and the rear bumpers.
● Certain vehicle conditions and surrounding environments, such a s the fol-
lowing, may affect the ability of the sensors to correctly dete ct objects. Pay
particular attention in the following situations. Failure to do so may result in
the vehicle being driven unsafely, possibly leading to an accident.
• When there is dirt, snow or ice on a sensor (Cleaning the sens or will
resolve this problem.)
• When the sensor is frozen (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen ma y show an
abnormal display, or objects may not be detected
• When a sensor is covered in any way
• When the vehicle is leaning considerably to one side
• When driving on an extremely bumpy road, incline, gravel, or g rass
• When the vicinity of the vehicle is noisy due to vehicle horns , motorcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves
• When there is another vehicle equipped with parking assist sen sor in the
vicinity
• When the sensor is coated with a sheet of spray or heavy rain
• When the vehicle is equipped with a fender pole or wireless an tenna
• When a towing eyelet is installed
• When a bumper or sensor receives a strong impact
• A backlit license plate, license plate holder, etc., are insta lled.
• When the vehicle is approaching a tall or curved curb
• When driving in harsh sunlight or intense cold weather
• When an object is directly under a bumper
• When objects become too close to the sensors
• When a non-genuine Toyota suspension (lowered suspension, etc. ) is
installed
In addition to the situations above, there are instances in which, because of
their shape, signs and other objects may be judged by the senso r to be
closer than they are.

Vehicle height can be adjusted
only when the engine is running.
The selected height mode will be
shown on the electronically modu-
lated air suspension display.
The selected mode will flash while
the height mode is being change.
: If equipped
The electronically modulated air suspension allows the driver t o
control the vehicle’s height in order to adjust for driving condi-
tions.
Select the desired height with the height control switch.

■Automatic leveling function
Regardless of the number of occupants or the luggage load, vehi cle height in
any mode is always adjusted to a fixed height by the automatic leveling func-
tion.
■ 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 e xceeds
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 suspension will not operate in the fol-
lowing cases:
● The underbody of the vehicle is touching the surface of the roa d.
● 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 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 modulate d air suspen-
sion.
■ The electronically modulated air suspension failure warning
The warning message is displayed on the multi-information displ ay, and the
electronically modulated air suspension cannot be activated unt il the malfunc-
tion is corrected.
Stop the engine and start again. If the warning message turns off, the system
operating correctly. If the warning message continues to be displayed, have
your vehicle inspected by your Toyota dealer as soon as possibl e.

WARNING
■The electronically modulated air suspension must be turned off in the
following circumstances:
Otherwise, the automatic leveling function may cause the vehicl e’s height to
change, and you may catch part of your body in the vehicle, res ulting in an
unexpected accident:
● When driving through water such as shallow streams (Put the veh icle
height in “HI” mode and turn off the electronically modulated a ir suspen-
sion. Drive at 18 mph [30 km/h] or slower.)
● When jacking up the vehicle, installing tire chains or tying th e vehicle with
chains/wires for transportation via flat bed truck (Turn the sy stem 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 “N” mod e 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 w ell 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, re sulting
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, re sulting
in an accident.

If the “4LO” indicator, “4HI” indicator or the center different ial lock indi-
cator blinks
● If the “4LO” indicator continues to blink when shifting between “4H” and “4L”,
stop the vehicle completely, move the shift lever to N and oper ate the switch
again.
● If the shift lever is moved before the “4LO” indicator turns on /off, the transfer
mode may not be shifted completely. The transfer mode disengage s both
the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (At this time, the indic ator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic tr ansmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode.
To complete the shifting, stop the vehicle completely, return t he shift lever to
N, and confirm that the shift was completed (The indicator turn s on/off).
● If the engine coolant temperature is too low, transfer mode may not be able
to shift. When the engine is warmer, turn the switch again.
If the “4LO” indicator, “4HI” i ndicator or the center different ial lock indicator
continues to blink even after attempting the above, there may b e a malfunc-
tion in the engine, the brake system or the four-wheel drive sy stem. In this
case, you may not be able to shift between “2WD” and “4H”, “4H” and “4L”,
and the center differential lock may not be operable. Have the vehicle
inspected by your Toyota dealer immediately.
■ Shifting to the “4L” position
The VSC off indicator will come on.
If the center differential is locked, VSC is automatically turn ed off.
