3085-1. 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.624)
●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 tha t the total load exerted on the vehi cle is within the
range of the weight limits. ( →P.309)
●Ensure that the trailer load is secure.
●Supplementary outside rear view mir- rors should be added to the vehicle if
the traffic behind c annot be clearly
seen with standard mirrors. Adjust the extending arms of these mirrors on
both sides of the vehicle so that they
always provide maxi mum 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.
WARNING
Follow all the instructions described in
this section.
Failure to do so could cause an acci - dent resulting in death or serious
injury.
■Trailer towing precautions
When towing, make sure that none of
the weight limits are exceeded.
( →P.309)
■To avoid accident or injury
●Vehicles with compact spare tire: Do not tow a trailer when the com -
pact spare tire is installed on your
vehicle.
●Vehicles with emergency tire punc -
ture repair kit: Do not tow a traile r when the tire
installed is repa ired with the emer-
gency tire puncture repair kit.

3105-1. Before driving
Weight of the trailer itself plus the trailer
load should be within the maximum
towing capacity. Exceeding this weight
is dangerous. ( →P.618)
When towing a trailer, use a friction
coupler or friction st abilizer (sway con-
trol device).
Permissible drawbar load
Allocate the trailer load so that the
drawbar load is g reater than 25 kg
(55.1 lb.) or 4% of the towing capacity.
Do not let the draw bar load exceed the
indicated weight. ( →P.618)
■Information tag (manufac-
turer’s label)
Gross vehicle mass
The combined weight of the driver, pas -
sengers, luggage, towing hitch, total
curb mass and drawbar load should not
exceed the gross vehicle mass by more
than 100 kg (220.5 lb.). Exceeding this
weight is dangerous.
Maximum permissible rear axle
capacity
The weight borne by the rear axle
should not exceed the maximum per -
missible rear axle capacity by 15% or
more. Exceeding this weight is danger -
ous.
The values for towing capacity were
derived from testing conducted at sea
level. Take note t hat hybrid system out-
put and towing capacity will be reduced
at high altitudes.

WARNING
■When the gross vehicle mass or
maximum permissible axle capacity is exceeded
Failing to observe this precaution may
lead to an accident causing death or
serious injury.
●Add an additional 20.0 kPa (0.2
kgf/cm2 or bar, 3 psi) to the recom -
mended tire inflation pressure
value. ( →P.624)
●Do not exceed the established
speed limit for towing a trailer in built-up areas or 100 km/h (62
mph), whichever is lower.

*: If equipped
The system can detect the follow -
ing:
 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 wil l 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 fr ontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
PCS (Pre-Collision Sys-
tem)*
The pre-collision system uses
a radar sensor and front cam -
era to detect objects ( →P.355)
in front of the vehicle. When
the system determines that the
possibility of a fr ontal 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 fronta l 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.
