2965-1. Before driving
■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.
■When towing a trailer
Disable the following systems, as the
systems may not operate properly.
●LTA (Lane Tracing Assist) (if
equipped) (P.353)
●Dynamic radar cruise control with full-
speed range (if equipped) (P.368)
●Cruise control (if equipped) (P.381)

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.

5-3.Operating the lights and wipers
Operating the switch turns
on the lights as follows:
1 The front position, tail,
license plate and instrument
panel lights turn on.
2 The headlights and all lights
listed above turn on.
3 The headlights, daytime
running lights ( P.326) and all
the lights listed above turn on
and off automatically.
■AUTO mode can be used when
The power switch is in ON.
■Daytime running light system
To make your vehicle more visible to
other drivers during daytime driving, the
daytime running lights turn on automati-
cally whenever the hybrid system is
started and the parking brake is
released with the headlight switch in the
position. (Illuminate brighter than
the front position lights.) Daytime run-
ning lights are not designed for use at
night.
■Headlight control sensor
The sensor may not function properly if an object is placed on the sensor, or
anything that blocks the sensor is affixed to the windshield. Doing so inter-feres with the sensor detecting the level
of ambient light and may cause the automatic headlight system to malfunc-tion.
■Automatic light off system
●When the light switch is in or
position: The headlights and front fog
lights turn off after the power switch is
turned to ACC or OFF.
●When the light switch is in posi-
tion: The headlights and all lights turn
off after the power switch is turned to
ACC or OFF.
To turn the lights on again, turn the
power switch to ON, or turn the light
switch to position once and then
back to or position.
■Light reminder buzzer

*: If equipped
The system can detect the follow-
ing (The detectable objects differs
depending on the function.):
Vehicles
Bicyclists
Pedestrians
■Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning message will be displayed
on the multi-information display to
urge the driver to take evasive
action.
■Pre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
■Emergency steering assist
If the system determines that the
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.

PKSB (Parking Support
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 the possibility
of a collision with a detected
object is high, a warning oper-
ates 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 automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.

Brake) system
WARNING
■Cautions regarding the use of the system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the
safety of the surroundings of the vehi- cle.
Depending on the vehicle and road
conditions, weather, etc., the system may not operate.
The detection capabilities of sensors
and radars are limited. Always drive while checking the safety of the sur-roundings of the vehicle.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your sur- roundings. 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 operations 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 Brake 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.
