the radar sensor and front camera,
preventing the system from operating
properly:

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.
●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.
●Vehicle is driven in a temporary lane or restricted lane due to con-struction work.
●Vehicle is driven in a construction zone.
●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 LTA 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.

Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
WARNING
●When there is rain, snow, etc. on the front surface of the radar or
front camera
●In traffic conditions that require fre-
quent repeated acceleration and deceleration
●When your vehicle is towing a trailer or during emergency towing
●When an approach warning buzzer is heard often

●Actual vehicle speed is more than
approximately 16 km/h (10 mph) below the set vehicle speed.
●Actual vehicle speed falls below approximately 30 km/h (20 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off.
●Pre-collision braking is activated.
●The parking brake is operated.
If constant speed control mode is auto-
matically canceled for any reasons other
than the above, there may be a malfunc-
tion in the system. Contact any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
■The Dynamic Radar Cruise Control with Road Sign Assist may not
operate properly when (vehicles with RSA)
As the Dynamic Radar Cruise Control
with Road Sign Assist may not operate properly in conditions in which RSA may not operate or detect correctly
( P.375), when using this function, make sure to check the speed limit sign displayed.
In the following situations, the set speed may not be changed to the recognized speed limit by pressing and holding the
“+RES”/“-SET” switch.
●If speed limit information is not avail-
able
●When the recognized speed limit is
the same as the set speed
●When the recognized speed limit is
outside of the speed range that the dynamic radar cruise control system can operate
■Brake operation
A brake operation sound may be heard and the brake pedal response may change, but these are not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control with full-speed range
Warning messages and buzzers are
used to indicate a system malfunction or to inform the driver of the need for cau-tion while driving. If a warning message
is shown on the multi-information dis- play, read the message and follow the instructions. ( P.353, 578)
■When the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend- ing on the conditions, operate the brake
pedal when deceleration of the system is insufficient or operate the accelerator pedal when acceleration is required.
As the sensor may not be able to cor- rectly detect these types of vehicles, the approach warning ( P.383) may not be
activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane
●Vehicles with small rear ends (trailers with no load on board, etc.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the
surrounding vehicles hinders the detecting of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage compartment, etc.)

a strong impact to the sensor or its
surrounding area

wet with standing water during bad
weather, such as heavy rain, snow, or
fog

in speed between your vehicle and
the vehicle that enters the detection
area

4385-5. Using the driving support systems
■ECB (Electronically Con-
trolled Brake System)
The electronically controlled sys-
tem generates braking force corre-
sponding to the brake operation
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when
the brakes are applied suddenly, or
if the brakes are applied while driv-
ing on a slippery road surface
■Brake assist
Generates an increased level of
braking force after the brake pedal
is depressed when the system
detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving suddenly or turning
on slippery road surfaces.
■VSC+ (Vehicle Stability Con-
trol+)
Provides cooperative control of the
ABS, TRC, VSC and EPS.
Helps to maintain directional stabil-
ity when swerving on slippery road
surfaces by controlling steering per-
formance.
■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying brake
pressure for individual wheels and
reducing driving torque when trailer
sway is detected.
■TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
■Active Cornering Assist (ACA)
Helps to prevent the vehicle from
drifting to the outer side by perform-
ing inner wheel brake control when
attempting to accelerate while turn-
ing
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel
Driving assist systems
To keep driving safety and per-
formance, the following sys-
tems operate automatically in
response to various driving sit-
uations. Be aware, however,
that these systems are supple-
mentary and should not be
relied upon too heavily when
operating the vehicle.
