tem. The LTA system does not automatically drive the vehicle or
reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always
assume full responsibility for driving
safely by paying careful attention to
the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also,
the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful
attention may lead to an accident, resulting in death or serious injury.
●When not using the LTA system, use the LTA switch to turn the sys-
tem off.

*: If equipped
■Parking Support Brake func-
tion (static objects) (if
equipped)
Ultrasonic sensors are used to
detect static objects, such as a wall,
in the detection area when driving
at a low speed or backing up.
( P. 2 8 3 )
■Parking Support Brake func-
tion (rear-crossing vehicles) (if
equipped)
Rear radar sensors are used to
detect approaching vehicles in the
PKSB (Parking Suppor t
Brake)*
The Parking Support Brake
system consists of the follow-
ing functions that operate
when driving at a low speed or
backing up, such as when
parking. When the system
determines that a collision with
a detected object is high, a
warning operates to urge the
driver to take evasive action. If
the system determines that the
possibility of a collision with a
detected object is extremely
high, the brakes are automati-
cally applied to help avoid the
collision or help reduce the
impact of the collision.

■Cautions regarding the use of
the system
Do not overly rely on the system, as
doing so may lead to an accident.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your
surroundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity
of collisions. However, it may not operate in some situations.
●The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the
system has stopped the vehicle, it is necessary to depress the brake
pedal immediately as brake control
will be canceled after approximately 2 seconds.
●It is extremely dangerous to check the system operatio ns by intention-
ally driving the vehicle into the
direction of a wall, etc. Never attempt such actions.
■When to disable the Parking Sup-port Brake
In the following situations, disable the
Parking Support Br ake as the system may operate even though there is no
possibility of a collision.
●When inspecting the vehicle using
a chassis roller, chassis dynamo or
free roller
●When loading the vehicle onto a
boat, truck or other transport vessel
●If the suspension has been modi-
fied or tires of a size other than specified are installed
●If the front of the vehicle is raised or lowered due to the carried load
●When equipment that may obstruct a sensor is installed, such as a tow-
ing eyelet, bumper protector (an
additional trim strip, etc.), bicycle carrier, or snow plow
●When using automatic car washing devices
●If the vehicle cannot be driven in a stable manner, such as when the
vehicle has been in an accident or
is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When a tire chains, compact spare
tire or an emergency tire puncture
repair kit is used
NOTICE
■If “Parking Support Brake Una- vailable” is displayed on the
multi-information display and the
PKSB OFF indicator is flashing
If this message is displayed immedi-
ately after the engine switch is
changed to ON, operate the vehicle carefully, paying attention to your
surroundings. It may be necessary to
drive the vehicle for a certain amount of time before the system returns to
normal. (If the system does not return
to normal after driving for a while, clean the sensors and their surround-
ing area on the bumpers.)

WA R N I N G
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not
attempt to use hill-start assist con-
trol to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
■When the TRC/VSC is activated
The slip indicator light flashes. Always
drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a
speed appropriate to the road condi- tions. As these are the systems to
help ensure vehicle stability and driv-
ing force, do not turn the TRC/VSC systems off unless necessary.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pattern
and total load capacity. In addition, make sure that the tires are inflated to
the recommended tire inflation pres-
sure level. The ABS, TRC and VSC systems will
not function correctly if different tires
are installed on the vehicle. Contact any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■Handling of tires and the suspen-sion
Using tires with any kind of problem
or modifying the suspension will affect the driving assist systems, and may
cause a system to malfunction.
If you make no extreme correction
with the steering or brakes, your vehi-
cle and trailer should stabilize. (P.153)
■Secondary Collision Brake (if equipped)
Do not rely solely upon the Secondary
Collision Brake. This system is designed to help reduce the possibil-
ity of further damage due to a second-
ary collision, however, that effect changes according to various condi-
tions. Overly relying on the system
may result in death or serious injury.

4127-1. Maintenance and care
NOTICE
●To prevent the wheels from corrod-
ing, remove any dirt and store in a
place with low humidity when stor- ing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic
substances or scrub with a hard
brush.
This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the
lenses.
■To prevent damage to the wind-
shield wiper arms
When lifting the wiper arms away
from the windshield, pull the driver
side wiper arm upward first, and repeat for the passenger side. When
returning the wipers to their original
position, do so from the passenger side first.
■When using an automatic car wash (vehicles with rain-sensing
windshield wipers)
Set the wiper switch to the off posi- tion. If the wiper switch is in “AUTO”,
the wipers may operate and the wiper
blades may be damaged.
■When using a high pressure car
wash
●Vehicles with rear view monitor sys-
tem: When washing the vehicle, do
not spray the camera or its sur- rounding area directly with a high
pressure washer. Shock applied
from high pressure water may cause the device to not operate
normally.
●Do not bring the nozzle tip close to boots (rubber or resin manufac-
tured cover), connectors or the fol-
lowing parts. The parts may be damaged if they come into contact
with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
•Brake parts
●Keep the cleaning nozzle at least
30 cm (11.9 in.) away from the vehi- cle body. Otherwise resin section,
such as moldings and bumpers,
may be deformed and damaged. Also, do not continuously hold the
nozzle in the same place.
●Do not spray the lower part of the
windshield continuously. If water
enters the air c onditioning system intake located near the lower part of
the windshield, the air conditioning
system may not operate correctly.
●Do not wash the underside of the
vehicle using a high pressure car washer.
