WARNING
QBefore using LTA system
ODo 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.
OFailure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
OWhen not using the LTA system, use the LTA switch to turn the sys-
tem off.
QSituations 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.
OVehicle is driven on a road surface which is slippery due to rainy
weather, fallen snow, freezing, etc.
OVehicle is driven on a snow-cov-
ered road.
OWhite (yellow) lines are difficult to
see due to rain, snow, fog, dust, etc.
OVehicle is driven in a temporary lane or restricted lane due to con-struction work.
OVehicle is driven in a construction zone.
OA spare tire, tire chains, etc. are equipped.
OWhen the tires have been exces-sively worn, or when the tire infla-tion pressure is low.
OWhen your vehicle is towing a trailer or during emergency towing
QPreventing LTA system malfunc-tions and operations performed
by mistake
ODo not modify the headlights or place stickers, etc. on the surface of
the lights.
ODo 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.
ODo not install or place anything on
the hood or grille. Also, do not install a grille guard (bull bars, kan-garoo bar, etc.).
OIf your windshield needs repairs, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
QConditions 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.

5-5. Using the driving support systems
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
OWhen there is rain, snow, etc. on the front surface of the radar or
front camera
OIn traffic conditions that require fre-
quent repeated acceleration and deceleration
OWhen your vehicle is towing a trailer or during emergency towing
OWhen an approach warning buzzer is heard often

3425-5. Using the driving support systems
If vehicle-to-vehicle distance control
mode is automatically canceled for any
reasons other than the above, there
may be a malfunction in the system.
Contact any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer.
QAutomatic cancelation of constant
speed control mode
Constant speed control mode is auto-
matically canceled in the following situa-
tions:
OActual vehicle speed is more than
approximately 16 km/h (10 mph)
below the set vehicle speed.
OActual vehicle speed falls below
approximately 30 km/h (20 mph).
OVSC is activated.
OTRC is activated for a period of time.
OWhen the VSC or TRC system is
turned off.
OWhen the brake control or output
restriction control of a driving support
system operates.
(For example: Pre-Collision System,
Drive-Start Control)
OThe 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.
QThe 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.331), 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.
OIf speed limit information is not avail-
able
OWhen the recognized speed limit is
the same as the set speed
OWhen the recognized speed limit is
outside of the speed range that the
dynamic radar cruise control system
can operate
QBrake operation
A brake operation sound may be heard
and the brake pedal response may
change, but these are not malfunctions.
QWarning 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.309, 518)
QWhen 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.339) may not be
activated.
OVehicles that cut in suddenly
OVehicles traveling at low speeds
OVehicles that are not moving in the
same lane
OVehicles with small rear ends (trailers
with no load on board, etc.)

cle and a following vehicle is short
• When there is a significant difference
in speed between your vehicle and

QSituations in which the system may
operate even if there is no possibil-
ity of a collision
Instances of the RCTA function unnec-
essarily detecting a vehicle and/or
object may increase in the following situ-
ations:

3925-5. Using the driving support systems
QVSC+ (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.
QTrailer 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.
QTRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
QActive 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
QHill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
QEPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel.
QE-Four (Electronic On-Demand
AWD system)
Automatically controls the drive
system such as to front-wheel drive
or AWD (all wheel drive) according
to various running conditions
including normal driving, during cor-
nering, on a uphill, when starting
off, during acceleration, on a slip-
pery roads due to snow or rain,
thus contributing to stable
operability and driving stability.
QEmergency brake signal
When the brakes are applied sud-
denly, the emergency flashers
automatically flash to alert the vehi-
cle behind.
QThe Secondary Collision
Brake (if equipped)
When the SRS airbag sensor
detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the vehicle speed and
help reduce the possibility of further
damage due to a secondary colli-
sion.
QWhen the TRC/VSC/ABS/Trail
Mode/Trailer Sway Control systems
are operating
The slip indicator light will flash while the
TRC/VSC/ABS/Trail Mode/Trailer Sway
Control systems are operating.
