3185-2. Driving procedures
■When the ambient temperature is
low, such as during winter driving conditions
●When starting the hy brid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is
until the “READY” indicator is steady on, as steady means the vehicle is
able to move.
●When the hybrid bat tery (traction bat-
tery) is extremely cold (below approxi -
mately -30°C [-22°F]) under the influence of the outside temperature, it
may not be possible to start the hybrid
system. In this case, try to start the hybrid system again after the tem -
perature of the hybrid battery
increases due to t he outside tempera- ture increase etc.
■Sounds and vibrations specific to a
hybrid vehicle
→ P.91
■If the 12-volt battery is discharged
The hybrid system cannot be started
using the smart en try & start system.
Refer to P.606 to res tart the hybrid sys- tem.
■Electronic key battery depletion
→ P.202
■Conditions affecting operation
→ P.225
■Note for the entry function
→ P.225
■Steering lock function
●After turning the power switch to OFF and opening and clos ing the doors,
the steering wheel will be locked due
to the steering lock function. Operat -
ing the power switch again automati- cally cancels the steering lock.
●When the steering lock cannot be released, “Push Power Switch while
Turning Steering Wheel in Either
Direction” will be displayed on the multi-information display.
Check that the shift lever is set in P.
Press the power switch shortly and
firmly while turning the steering wheel
left and right.
●To prevent the st eering lock motor
from overheating, the motor may be suspended if the hybrid system is
turned on and off repeatedly in a short
period of time. In this case, refrain from operating the power switch. After
about 10 seconds, the steering lock
motor will resume functioning.
■If there is a malfunction in the smart entry & start system
If “Smart Entry & St art System Malfunc-
tion” is displayed on the multi-informa - tion display, the system may be
malfunctioning. Have the vehicle
inspected by any a uthorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer immediately.
■If the “READY” indicator does not
come on
In the event that the “READY” indicator
does not come on even after performing
the proper procedures for starting the vehicle, contact any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer immediately.
■If the hybrid system is malfunction - ing
→ P.99
■Electronic key battery
→ P.543
■Operation of the power switch
●If the switch is not pressed shortly and
firmly, the power switch mode may not
change or the hybri d system may not start.
●If attempting to restart the hybrid sys - tem immediately after turning the

WARNING
■Limitations of the pre-collision
system
●The driver is solely responsible for safe driving. Always drive safely,
taking care to observe your sur -
roundings. Do not use the pre- collision system
instead of normal braking opera -
tions under any circumstances.
This system will not prevent colli - sions or lessen collision damage or
injury in every situation. Do not
overly rely on thi s system. 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 effec - tiveness may change according to
various conditions, therefore the
system may not alw ays be able to achieve the same level of perfor -
mance.
Read the following conditions care - fully. Do not over ly rely on this sys-
tem and always drive carefully.
• Conditions under which the system may operate even if there is no pos -
sibility of a collision: →P.359
• Conditions under which the system may not operate properly: →P.360
●Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects imitating detectable objects,
etc.), the system m ay not operate
properly, possibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be applied.
●If the vehicle is stopped by the operation of the pre-collision brak -
ing function, the p re-collision brak-
ing function operation will be canceled after approximately 2 sec -
onds. Depress the brake pedal as
necessary.
●The pre-collision braking function
may not operate if certain opera - tions are performed by the driver. If
the accelerator pedal is being
depressed strongly or the steering wheel is being turned, the system
may determine that the driver is tak -
ing evasive action and possibly pre - vent the pre-col lision braking
function from operating.
●In some situations, while the pre-
collision braking function is operat -
ing, operation of the function may be canceled if the accelerator pedal
is depressed strongly or the steer -
ing wheel is tur ned and the system determines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may deter -
mine that the driv er is taking eva- sive action and possibly delay the
operation timing of the pre-collision
braking function.
■When to disable the pre-colli -
sion system
In the following situations, disable the
system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing
another vehicle
●When transporting the vehicle via truck, boat, train or similar means of
transportation
●When the vehicle is raised on a lift
with the hybrid system on and the
tires are allowed to rotate freely

■Enabling/disabling the pre-col -
lision system
The pre-collisio n system can be
enabled/disabled on the screen
( →P.186) of the multi-information
display.
The system is automa tically enabled
each time the power switch is turned to
ON.
If the system is disabled, the PCS
warning light will turn on and a
message will be di splayed on the
multi-information display.
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on the screen
( →P.186) of the multi-information
display.
The warning timing setting is retained
when the power switch is turned to
OFF. However, if the pre-collision sys-
tem is disabled and re-enabled, the
operation timing will return to the
default setting (middle).
WARNING
●When inspecting the vehicle using
a drum tester su ch as a chassis
dynamometer or speedometer tes- ter, or when using an on vehicle
wheel balancer
●When a strong impact is applied to
the front bumper or front grille, due
to an accident or other reasons
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated

*: If equipped
RSA (Road Sign Assist)*
The RSA system recognizes
specific road signs using the
front camera and/or naviga -
tion system (when speed limit
information is available) to pro -
vide information to the driver
via the display.
If the system judges that the
vehicle is being driven over the
speed limit, performing prohib -
ited actions, etc. according to
the recognized road signs, it
notifies the driver through a
visual notification and notifica -
tion buzzer or steering wheel
vibration.
WARNING
■Before using the RSA
Do not rely solely upon the RSA sys- tem. RSA is a system which supports
the driver by providing information,
but it is not a replacement for a driver’s own vision and awareness.
Drive safely by always paying careful
attention to the traffic rules.

5-5. Using the driving support systems
Driving
system will notify the driver.
When the vehicle speed exceeds
the speed notific ation threshold
of the speed limit sign displayed,
the sign display will be empha -
sized and a buzzer will sound.
When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map
information of the navigation sys -
tem, the no-entry sign flashes
and a buzzer will sound. (For
vehicles with navigation system)
If it is detected that your vehicle
is overtaking when a no overtak -
ing sign is displayed on the multi-
information display, the dis -
played sign will flash and a steer -
ing wheel will vibrate.
Depending on the situation, traffic
environment (traffic direction,
speed unit) may be detected incor -
rectly and a notification function
may not operate properly.
■Setting procedure
→ P.186
■Automatic turn-off of RSA sign dis-
play
One or more signs automatically turn off
in the following situations.
●No sign has been recognized for a
certain distance.
●The road changes due to a left or right
turn, etc.
■Conditions in which the function
may not operate or detect correctly
In the following situations, RSA does not
operate normally and may not recognize
signs, display the i ncorrect sign, etc.
However, this does not indicate a mal - function.
●The front camera is misaligned due to a strong impact being applied to the
sensor, etc.
●Dirt, snow, stickers, etc. are on the
windshield near the front camera.
●In inclement weather such as heavy
rain, fog, snow or sand storms.
●Light from an oncoming vehicle, the
sun, etc. enters the front camera.
●The sign is dirty, f aded, tilted or bent.
●The contrast of electronic sign is low.
●All or part of the sign is hidden by the
leaves of a tree, a pole, etc.
●The sign is only visi ble to the front
camera for a short amount of time.
●The driving scene (turning, lane
change, etc.) is judged incorrectly.
●If a sign not appropriate for the cur -
rently traveled lane, but the sign exists dir e ct ly a ft er a f r eew ay br an ch es , or in
an adjacent lane ju st before merging.
●Stickers are attached to the rear of the
preceding vehicle.
●A sign resembling a system compati-
ble sign is recognized.
●Side road speed signs may be
detected and displa yed (if positioned
in sight of the front camera) while the vehicle is traveling on the main road.
●Roundabout exit road speed signs may be detected and displayed (if
positioned in sight of the front camera)
while traveling on a roundabout.
●The front of the vehicle is raised or
lowered due to the carried load.
●The surrounding br ightness is not suf-
ficient or changes suddenly.

3805-5. Using the driving support systems
When a vehicle is de tected running ahead of you, the system automatically deceler-
ates your vehicle. When a great er 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 war ns 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 sto p (vehicle is stopped
by system control). After the veh icle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume 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 t o an overtaking lane
while driving at 50 mph (80 km/h) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the ste ering wheel in the vehicle (left side driver position
versus right side driv er position.) If the vehicle is driven to a region where the over-
taking lane is on a different sid e from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if th e driver normally operates the vehicle in a region
where the overtaking lane is to t he 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.
