■ Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.

WARNING
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting in
death or serious injury.
■ Stopping the engine in an emergency
● If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 2 seconds, or press it
briefly 3 times or more in succession. ( P. 681)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering
or braking control, but the power assist to these systems will be lost. This
will make it more difficult to steer and brake, so you should pull over and
stop the vehicle as soon as it is safe to do so.
● If the engine switch is operated while the vehicle is running, a warning
message will be shown on the multi-information display and a buzzer
sounds.
● Vehicles with a Multidrive: When restarting the engine after it was turned
off while driving, shift the shift lever to N and press the engine switch.
● Vehicles with a manual transmission: When restarting the engine after it
was turned off while driving, shift the shift lever to N, depress the clutch
pedal and press the engine switch.

The Toyota Safety Sense consists of the following drive assist
systems and contributes to a safe and comfortable driving expe-
rience:
WARNING
■ Toyota Safety Sense
The Toyota Safety Sense is designed to operate under the assumption that
the driver will drive safely, and is designed to help reduce the impact to the
occupants and the vehicle in the case of a collision or assist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’s surround-
ings and driving safely.

WARNING
■Limitations of the pre-collision system
● The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.
● Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 308
• Conditions under which the system may not operate properly: P. 3 11
● Do not attempt to test the operation of the pre-collision system yourself, as
the system may not operate properly, possibly leading to an accident.
■ Pre-collision braking
● The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is bei ng turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.
● In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.
● If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.

■ Pedestrian detection function*
*: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available.
■ Cancelation of the pre-collision braking
● If either of the following occur while the pre-collision braking function is
operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
■ Conditions under which the system may operate even if there is no pos-
sibility of a collision
● In some situations such as the following, the system may determine that
there is a possibility of a frontal collision and operate.
• When passing a vehicle or pedestrian
• When changing lanes while overtaking a preceding vehicle
• When overtaking a preceding vehicle that is changing lanes
The pre-collision system detects pedestri-
ans based on the size, profile, and motion
of a detected object. However, a pedes-
trian may not be detected depending on
the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. ( P. 313)
• When overtaking a preceding vehicle
that is making a left/right turn
• When passing a vehicle in an oncom-
ing lane that is stopped to make a
right/left turn

LDA (Lane Departure Alert with steering
control)
When driving on highways and freeways with white (yellow) lines, this
function alerts the driver when the vehicle might depart from its lane
and provides assistance by operating the steering wheel to keep the
vehicle in its lane.
The LDA system recognizes visi-
ble white (yellow) lines with the
camera sensor on the upper por-
tion of the front windshield.

◆Steering control function
When the system determines
that the vehicle might depart
from its lane, the system pro-
vides assistance as necessary
by operating the steering wheel
in small amounts for a short
period of time to keep the vehi-
cle in its lane.
If the system detects that the
steering wheel has not been
operated for a fixed amount of
time or the steering wheel is not
being firmly gripped, a warning
is displayed on the multi-infor-
mation display and the function
is temporarily canceled.
