turned to OFF but instead be turned
to ACC. Perform the following pro -
cedure to turn the switch to OFF:
1 Check that the parking brake is
set.
2 Shift the shift lever to P.
3 Check that “IGNITION ON” is
displayed on the multi-informa -
tion display and press the power
switch shortly and firmly.
4 Check that “ACCESSORY” or
“IGNITION ON” on the multi-
information display is off.
*1: To improve fuel efficiency and
reduce noise, shift the shift lever to
D for normal driving.
*2: Vehicles with paddle shift switches
only: Selecting shift ranges in the D
position allows suitable use of
engine braking. ( →P.323)
*3: By selecting shift ranges using S
mode, you can control accelerating
force and engine braking force.
■When driving with dynamic radar
cruise control with full-speed range or cruise control activated (if
equipped)
Even when performing the following actions with the intent of enabling
engine braking, engine braking will not
activate because dyn amic radar cruise control with full-speed range, or cruise
control will not be canceled.

1 Upshifting
2 Downshifting
The selected shift range, from D1 to
D6, will be displayed on the multi-infor -
mation display.
■Shift ranges and their functions
●You can choose from 6 levels of
accelerating force and engine braking force.
●A lower shift range will provide greater accelerating force and engine braking
force than a higher shift range, and
the engine revolutions will also increase.
■Downshifting restriction warning

To help ensure safe ty and driving per- formance, downshifting operation may
sometimes be restricted. In some cir -
cumstances, downshifting may not be possible even when the paddle shift
switch is operated. (A buzzer will sound
twice.)
■Automatic deacti vation of shift
range selection i n the D position
Shift range selection in the D position
will be deactivated in the following situa -
tions:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed
for more than a cert ain period of time
●When the shift lever is shifted to a
position other than D
●When the “+” paddle shift switch is
held down for a period of time
When the shift lever is in the S posi -
tion, the shift lev er or paddle shift
switches (if equipped) can be oper -
ated as follows:
1 Upshifting
2 Downshifting
The selected shift range, from S1 to S6,

Driving
■S mode
●You can choose from 6 levels of
accelerating force and engine braking force.
●A lower shift range will provide greater accelerating force and engine braking
force than a higher shift range, and
the engine revolutions will also increase.
●To prevent the eng ine from over-rev- ving, upshifting may automatically
occur when the shif t range is 3 or
lower.
●When the shift range is 4 or lower,
holding the shift le ver toward “+” sets the shift range to 6.
■Downshifting restriction warning
buzzer
To help ensure safe ty and driving per- formance, downshifting operation may
sometimes be restricted. In some cir -
cumstances, downshifting may not be possible even when the shift lever or
paddle shift switches (if equipped) is
operated. (A buzze r will sound twice.)
■If the “S” indicator does not come on or the “D” indicator is displayed
even after shifting t he shift lever to
S
This may indicate a malfunction in the transmission system. Have the vehicle
inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer immediately. (In
this situation, the transmission will oper -
ate in the same manner as when the shift lever is in D.)

■If “Parking Assist Unavailable” is
displayed on the multi-information display (vehicles with PKSB)
Water may be continuously flowing over
the sensor surface, such as in a heavy rain. When the system determines that it
is normal, the system will return to nor-
mal.
■Sensor detection information
●The sensor’s detec tion areas are lim-
ited to the areas aro und the vehicle’s front and rear bumpers.
●The following situations may occur during use.
• Depending on the shape of the object
and other factors, t he detection dis- tance may shorten, or detection may
be impossible.
• Detection may be impossible if static objects draw too close to the sensor.
• There will be a shor t delay between
static object detec tion and display (warning buzzer sounds). Even at low
speeds, there is a possibility that the
object will come withi n 25 cm (9.8 in.) before the display is shown and the
warning buzzer sounds.
• It might be difficu lt to hear the buzzer due to the volume of the audio system
or air flow noise of the air conditioning
system. • It may be difficult to hear the sound of
this system due t o the buzzers of
other systems.
■Conditions under which the func -
tion may no t function correctly
Certain vehicle c onditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.
●There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor
is frozen the sensor display may be displayed abnormally, or objects, such
as a wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a sensor is extremely hot or cold.
●On an extremely bumpy road, on an incline, on grav el, 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 pro ducing 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.
●If a sensor is hit by a large amount of
water, such as when driving on a
flooded road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall or
curved curb.
●If objects draw too close to the sensor.
■Objects which may not be properly
detected
The shape of the object may prevent the sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro- jecting outwards in the direction of
your vehicle
