■Tire information
●Increase the tire inflation pressure to
20.0 kPa (0.2 kgf/cm2 or bar, 3 psi)
greater than the recommended value
when towing. (P.590)
●Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the val-
ues recommended by the manufac-
turer of your trailer.
■Safety checks before towing
●Check that the maximum load limit for
the towing hitch/bracket and hitch ball
is not exceeded. Bear in mind that the
coupling weight of the trailer will add
to the load exerted on the vehicle.
Also make sure that the total load
exerted on the vehicle is within the
range of the weight limits. (P.298)
●Ensure that the trailer load is secure.
●Supplementary outside rear view mir-
rors should be added to the vehicle if
the traffic behind cannot be clearly
seen with standard mirrors. Adjust the
extending arms of these mirrors on
both sides of the vehicle so that they
always provide maximum visibility of
the road behind.

Trailer towing
Your vehicle is designed pri-
marily as a passenger carry-
ing vehicle. Towing a trailer
will have an adverse effect on
handling, performance, brak-
ing, durability, and fuel con-
sumption. Your safety and
satisfaction depend on the
proper use of correct equip-
ment and cautious driving hab-
its. For your safety and the
safety of others, do not over-
load the vehicle or trailer.
To tow a trailer safely, use
extreme care and drive the
vehicle in accordance with the
trailer’s characteristics and
operating conditions.
Toyota warranties do not apply
to damage or malfunction
caused by towing a trailer for
commercial purposes.
Ask your local authorized
Toyota retailer or Toyota
authorized repairer, or any reli-
able repairer for further details
before towing, as there are
additional legal requirements
in some countries.

■The windshield wipers and washer can be operated when
The power switch is in ON.
■Effects of vehicle speed on wiper operation
With low speed windshield wiper opera-
tion selected, wiper operation will be switched from low speed to intermittent wiper operation when the vehicle is sta-
tionary. (However, when the sensor sen- sitivity is adjusted to the highest level, the mode will not switch.)
■Raindrop sensor
●The raindrop sensor judges the amount of raindrops. An optical sen-
sor is adopted. It may not operate properly when sunlight from the rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc. are present on the windshield.
●If the wiper switch is turned to the “AUTO” position while the power switch is in ON, the wipers will operate
once to show that “AUTO” mode is activated.
●If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
●If the temperature of the raindrop sen-
sor is 85°C (185°F) or higher, or -15°C (5°F) or lower, the automatic opera-tion may not occur. In this case, oper-
ate the wipers in any mode other than “AUTO”.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield washer fluid reservoir.
■Washer nozzle heaters (if
equipped)
The washer nozzle heaters operate to prevent frozen nozzle when the outside
temperature is 5°C (41°F) or less and the power switch is in ON.
WARNING
■Caution regarding the use of
windshield wipers in “AUTO” mode
The windshield wipers may operate
unexpectedly if the sensor is touched or the windshield is subject to vibra-tion in “AUTO” mode. Take care that
your fingers or anything else does not become caught in the windshield wip-ers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm. The fluid may freeze on the
windshield and cause low visibility. This may lead to an accident, result-ing in death or serious injury.
■When the washer nozzle heaters are operating (if equipped)
Do not touch the area around the washer nozzle, as they can become very hot and burn you.
NOTICE
■When the washer fluid tank is
empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■When a nozzle becomes blocked
In this case, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

possibility of a frontal collision is
high and that there is sufficient
space for the vehicle to be steered
PCS (Pre-Collision Sys-
tem)
*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects (P.343)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing operates to urge the driver
to take evasive action and the
potential brake pressure is
increased to help the driver
avoid the collision. If the sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high,
the brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.
