2064-5. Using the driving support systems
The LDA 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
*.
The front camera is used to
detect lane lines or a course
*.
*: Boundary between the asphalt and grass, soil, etc., or structures,
such as a curb, guardrail, etc.
■Lane departure alert func-
tion
When the system determines
that the vehicle might depart
from its lane or course
*, a warn-
ing is displayed on a display,
and either a warning buzzer will
sound or the steering wheel will
vibrate to alert the driver.
Check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane or course
*.
Vehicles with BSM: If the system
determines that the vehicle may
collide with a vehicle in an adjacent
lane, the lane de parture alert will
operate even if the turn signals are
operating.
*: Boundary between the asphalt and grass, soil, etc., or structures, such as a curb,
guardrail, etc.
■Lane departure prevention
function
If the system determines that
the vehicle is likely to depart
from its lane or course
*, it pro-
vides assistance through steer-
ing wheel operations to help
avoid deviation from the lane or
course.
If the system determines that the
steering wheel has not been oper-
ated for a certain amount of time or
the steering wheel is not being
firmly gripped, a warning message
may be displayed and a warning
buzzer may sound to alert the
driver.
Vehicles with BSM: If the system
determines that the vehicle may
collide with a vehicl e in an adjacent
lane, the lane departure prevention
function will operate even if the turn
signals are operating.

■Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performanc e of each sys-
tem. If non-Toyota parts are used in
replacement or if a repair shop other
than a Toyota dealer performs
repairs, confirm the warranty cover-
age.
■Allow inspection and repairs to
be performed by a Toyota
dealer
●Toyota technicians are
well-trained specialists and are
kept up to date with the latest ser-
vice information. They are well
informed about the operation of all
systems on your vehicle.
●Keep a copy of the repair order. It
proves that the maintenance that
has been performed is under war-
ranty coverage. If any problem
should arise while your vehicle is
under warranty, your Toyota
dealer will promptly take care of it.
General maintenance should be
performed on a daily basis. This
can be done by yourself or by a
Toyota dealer.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.
For details about maintenance
items and schedules, refer to the
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.
Maintenance require-
ments

ical driving, day-to-day care
