2224-1. Before driving
■Before towing
Check that the fo llowing conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.523)
●Trailer tires are inflated according
to the trailer manufacturer’s rec-
ommendation.
●All trailer lights work as required
by law.
●All lights work each time you con-
nect them.
●The trailer ball is set at the proper
height for the coupler on the
trailer.
●The trailer is level when it is
hitched.
Do not drive if th e trailer is not
level, and check for improper
tongue weight, overloading, worn
suspension, or other possible
causes.
●The trailer cargo is securely
loaded.
●The rear view mirr ors conform to
all applicable fede ral, state/provin-
cial or local regulations. If they do
not, install rear view mirrors
appropriate for towing purposes.
■When towing a trailer
Disable the following systems, as
the systems may no t operate prop-
erly.
●LTA (Lane Tracing Assist)
(  P.278)
Trailer towing (with
towing package)
Your vehicle is designed
primarily as a passenger-
and-load-carrying vehicle.
Towing a trailer can have an
adverse impact on handling,
performance, braking, dura-
bility, and fuel consump-
tion. For your safety and the
safety of others, you must
not overload your vehicle or
trailer. You must also
ensure that you are using
appropriate towing equip-
ment, that the towing equip-
ment has been installed
correctly and used properly,
and that you employ the
requisite driving habits.
Vehicle-trailer stability and
braking performance are
affected by trailer stability,
brake performance and set-
ting, trailer brakes, the hitch
and hitch systems (if
equipped).
To tow a trailer safely, use
extreme care and drive the
vehicle in accordance with
your trailer’s characteris-
tics and operating condi-
tions.
Toyota warranties do not
apply to damage or mal-
function caused by towing a
trailer for commercial pur-
poses.
Contact your Toyota dealer for
further information about addi-
tional requirements such as a
towing kit, etc.

2.0
The Toyota Safety Sense
2.0 consists of the following
drive assist systems and
contributes to a safe and
comfortable driving experi-
ence:
Driving assist system
WARNING
■Toyota Safety Sense 2.0
The Toyota Safety Sense 2.0 is
designed to operate under the
assumption that the driver will
drive safely, and is designed to
help reduce the impact to the
occupants and the vehicle in the
case of a collision or assist the
driver in normal driving condi-
tions.
As there is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’s su rroundings and
driving safely.

2784-5. Using the driving support systems
LTA (Lane Tracing
Assist)
While driving on a road with
clear white (yellow) lane
lines, the LTA system warns
the driver if the vehicle may
deviate from the current
lane or course
*, and also
can slightly operate the
steering wheel to help avoid
deviation from the lane or
course
*. Also, while the
dynamic radar cruise con-
trol with full-speed range
P.291 is operating, this sys-
tem will operate the steering
wheel to maintain the vehi-
cle’s lane position.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects
preceding vehicles using
the front camera and radar.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb
WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that m ust be paid to
the area in front of the vehicle.
The driver must always assume
full responsibilit y for driving
safely by paying careful atten-
tion to the surrounding condi-
tions and operating the steering
wheel to correct 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
driving operations and pay care-
ful attention may lead to an
accident, resulting in death or
serious injury.
●When not using the LTA sys-
tem, use the LTA switch to turn
the system off.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Vehicle is driven on a road sur-
face which is slippery due to
rainy weather, fallen snow,
freezing, etc.
●Vehicle is driven on a snow-cov-
ered road.
●White (yellow) lin es are difficult
to see due to rain, snow, fog,
dust, etc.
●Vehicle is driven in a temporary
lane or restricted lane due to
construction work.
