*: If equipped
LDA (Lane Depar ture
Alert with steering con-
trol)*
When driving on highways and
freeways with white (yellow)
lane lines, this function alerts
the driver when the vehicle
might depart from its lane or
course* and provides assis-
tance by operating the steering
wheel to keep the vehicle in its
lane or course*.
The LDA 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
WA R N I N G
■Before using LDA system
●Do not rely solely upon the LDA
system. The LDA system does not automatically drive the vehicle or
reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always
assume full responsibility for driving
safely by paying careful attention to
the surrounding conditions and operating the steering wheel to cor-
rect 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 driv-
ing operations and pay careful
attention may lead to an accident, resulting in death or serious injury.
●When not using the LDA system, use the LDA switch to turn the sys-
tem off.
■Situations unsuitable for LDA
system
In the following situations, use the LDA switch to turn the system off.
Failure to do so may lead to an acci-
dent, resulting in death or serious injury.
●Vehicle is driven on a road surface which is slippery due to rainy
weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-
ered road.
●White (yellow) lines are difficult to
see due to rain, snow, fog, dust,
etc.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been exces-
sively worn, or when the tire infla- tion pressure is low.

●When tires of a size other than
specified are installed.
●Vehicle is driven in traffic lanes
other than that highways and free-
ways.
●When your vehicle is towing a
trailer or during emergency towing
■Preventing LDA system malfunc-
tions and operations performed
by mistake
●Do not modify the headlights or
place stickers, etc. on the surface of
the lights.
●Do not modify the suspension etc. If
the suspension etc. needs to be replaced, contact any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●Do not install or place anything on
the hood or grille. Also, do not install a grille guard (bull bars, kan-
garoo bar, etc.).
●If your windshield needs repairs,
contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Conditions in which functions may not operate properly
In the following situations, the func-
tions may not operate properly and the vehicle may depart from its lane.
Drive safely by always paying careful
attention to your surroundings and operate the steering wheel to correct
the path of the vehicle without relying
solely on the functions.
●Vehicle is being driven around a
sharp curve.
●Objects or patterns that could be mistaken for white (yellow) lines are
present on the side of the road

■Before using dynamic radar
cruise control with full-speed
range
●Driving safely is the sole responsi-
bility of the driver. Do not rely solely
on the system, and drive safely by always paying careful attention to
your surroundings.
●The dynamic radar cruise control
with full-speed range provides driv-
ing assistance to reduce the driver’s burden. However, there are
limitations to the assistance pro-
vided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be cor-
rectly detecting the vehicle ahead:

2284-5. Using the driving support systems
WA R N I N G
• Conditions under which the vehi-
cle-to-vehicle distance control
mode may not function correctly: P. 2 3 7
●Set the speed appropriately depending on the speed limit, traffic
flow, road conditions, weather con-
ditions, etc. The driver is responsi-
ble for checking the set speed.
●Even when the system is function-
ing normally, the condition of the preceding vehicle as detected by
the system may differ from the con-
dition observed by the driver. Therefore, the driver must always
remain alert, assess the danger of
each situation and drive safely. Relying solely on this system or
assuming the system ensures
safety while driving can lead to an accident, resulting in death or seri-
ous injury.
●Switch the dynamic radar cruise
control with full-speed range setting
to off, using the cruise control main switch when not in use.
■Cautions regarding the driving assist systems
Observe the following precautions, as
there are limitations to the assistance provided by the system . Failure to do
so may cause an accident resulting in
death or serious injury.
●Assisting the driver to measure fol- lowing distance
The dynamic radar cruise control with
full-speed range is only intended to help the driver in determining the fol-
lowing distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mechanism
that allows careless or inattentive
driving, and it is not a system that can assist the driver in low-visibility condi-
tions.
It is still necessary for driver to pay close attention to the vehicle’s
surroundings.
●Assisting the driver to judge proper
following distance
The dynamic radar cruise control with full-speed range determines whether
the following distance between the
driver’s own vehicle and a designated vehicle traveling ahead is within a set
range. It is not capable of making any
other type of judgement. Therefore, it is absolutely necessary for the driver
to remain vigilant and to determine
whether or not there is a possibility of danger in any given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with
full-speed range does not include functions which will prevent or avoid
collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any possibility of danger, the driver must
take immediate and direct control of
the vehicle and act appropriately in order to ensure the safety of all
involved.
