LTA (Lane Tracing
Assist)
*
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
*. Furthermore,
the system provides steering
assistance when dynamic
radar cruise control with full-
speed range is operating to
keep the vehicle in its lane.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects pre-
ceding vehicles using the front
camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,

WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA 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 LTA system, use the LTA switch to turn the sys-
tem 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 acci- dent, resulting in death or serious injury.

Functions included in LTA
system

3805-5. Using the driving support systems
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped
by system control). After the vehicle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will resume follow-up cruising.
If the start-off operation is not performed, system control continues to keep your
vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in the opposite direction to
the overtaking lane (e.g., if the driver normally operates the vehicle in a region
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration
When there are no longer any preceding vehicles driving slower than the
set speed
The system accelerates until the set speed is reached. The system then returns to
constant speed cruising.

■Vehicles that can be detected
by the Blind Spot Monitor
The BSM function uses radar sen-
sors to detect the following vehicles
traveling in adjacent lanes and
advises the driver of the presence
of such vehicles via the indicators
WARNING
■Handling the radar sensor
Blind Spot Monitor sensors are
installed inside the left and right sides of the rear bumper respectively. Observe the following to ensure the
Blind Spot Monitor can function cor- rectly.
●Keep the sensors and the sur-rounding areas on the rear bumper clean at all times.
If a sensor or its surrounding area on the rear bumper is dirty or cov-ered with snow, the Blind Spot
Monitor may not operate and a warning message ( P.394) will be displayed. In this situation, clear off
the dirt or snow and drive the vehi- cle with the operation conditions of the BSM function ( P.410) satis-
fied for approximately 10 minutes. If the warning message does not dis-appear, have the vehicle inspected
by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not subject a sensor or its sur-rounding area on the rear bumper to a strong impact.
If a sensor is moved even slightly off position, the system may mal-function and vehicles may not be
detected correctly. In the following situations, have your vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor
is scratched or dented, or part of them has become disconnected.
●Do not disassemble the sensor.
●Do not attach accessories, stickers
(including transparent stickers), alu- minum tape, etc. to a sensor or its surrounding area on the rear
bumper.
●Do not modify the sensor or sur-
rounding area on the rear bumper.

make sure that the tires are inflated to the recommended tire inflation pres-sure level.
The ABS, TRC and VSC/Trailer Sway Control systems will not function cor-rectly if different tires are installed on
the vehicle. Contact any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer for further information when replacing tires or wheels.
■Handling of tires and the suspen-sion
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may
cause a system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations. Depending on many fac-
tors such as the conditions of the vehicle, trailer, road surface and driv-ing environment, the Trailer Sway
Control system may not be effective. Refer to your trailer owner’s manual for information on how to tow your
trailer properly.

4465-6. Driving tips
Perform the following according to
the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
 To ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte-
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
 Remove any snow or mud from
the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and move the
shift lever to P without setting the
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the park-
ing brake, make sure to block the
wheels.
Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
When the parking brake is in automatic
mode, release the parking brake after
shifting the shift lever to P. ( P.326)
If the vehicle is left parked with
the brakes damp in cold tem-
peratures, there is a possibility of
the brakes freezing.
 If the vehicle is parked without
setting the parking brake, con-
firm that the shift lever cannot be
moved out of P*.
*: The shift lever will be locked if it is
attempted to be shifted from P to any
other position without depressing the
brake pedal. If the shift lever can be
shifted from P, there may be a prob-
lem with the shift lock system. Have
the vehicle inspected by any autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer
immediately.
