Driving
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-
ing lane changes.
■Transmission information
To maintain engine braking effi-
ciency, when using engine braking,
do not use the transmission in D.
(P.321)
■If the hybrid system overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the hybrid system overheating. If
the high coolant temperature warn-
ing light indicates that the hybrid
system is overheating, turn the air
conditioning off immediately, leave
the road and stop the vehicle in a
safe place. (P.611)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P.
■Break-in schedule
Toyota recommends that vehicles fitted
with new power train components
should not be used for towing trailers for
the first 800 km (500 miles).
■Maintenance
●Maintenance must be performed more
frequently when using the vehicle for
towing due to the greater weight bur-
den placed on the vehicle compared
to normal driving.
●Retighten all bolts securing the hitch-
ing ball and bracket after towing for
approximately 1000 km (600 miles).
■If trailer sway occurs
One or more factors (crosswinds, pass-
ing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle
and trailer, causing instability.
3165-1. Before driving
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer
straight ahead.
Do not try to control trailer swaying by
turning the steering wheel.
• Begin releasing the accelerator pedal
immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply
vehicle brakes.
If you make no extreme correction with
the steering or brakes, your vehicle and
trailer should stabilize (if enabled, Trailer
Sway Control can also help to stabilize
the vehicle and trailer.).
●After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants
out of the vehicle.
• Check the tires of the vehicle and the
trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appro-
priate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not overloaded
after occupants get in.
If you cannot find any problems, the
speed at which trailer swaying occurred
is beyond the limit of your particular
vehicle-trailer combination. Drive at a
lower speed to prevent instability.
Remember that swaying of the towing
vehicle-trailer increases as speed
increases.
3185-2. Driving procedures
■When the ambient temperature is
low, such as during winter driving
conditions
●When starting the hybrid 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 battery (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 the outside tempera-
ture increase etc.
■Sounds and vibrations specific to a
hybrid vehicle

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 steering 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 & Start System Malfunc-
tion” is displayed on the multi-informa-
tion display, the system may be
malfunctioning. Have the vehicle
inspected by any authorized 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.

the multi-information display.
WARNING
■When starting the hybrid system
Always start the hybrid system while
sitting in the driver’s seat. Do not depress the accelerator pedal while starting the hybrid system under any
circumstances. Doing so may cause an accident resulting in death or serious injury.
■Caution while driving
If hybrid system 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 acci-dent, resulting in death or serious
injury.
NOTICE
■When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by
any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer immediately.
■Symptoms indicating a malfunc-tion with the power switch
If the power switch seems to be oper- ating somewhat differently than usual, such as the switch sticking slightly,
there may be a malfunction. Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer immediately.
Stopping the hybrid system
WARNING
■Stopping the hybrid system in an emergency
●If you want to stop the hybrid sys-tem in an emergency while driving the vehicle, press and hold the
power switch for more than 2 sec- onds, or press it briefly 3 times or more in succession. ( P.560)
However, do not touch the power switch while driving except in an emergency. Turning the hybrid sys-
tem off while driving will not cause a loss of steering or braking control. However, power assist for the
steering wheel may be lost making it difficult to steer smoothly before stopping the vehicle depending on
the remaining charge in the 12-volt battery or usage conditions. In this situation, you should pull over and
stop the vehicle as soon as it is safe to do so.

Driving
The Automatic High Beam indicator will
come on when the system is operating.
■High beams automatic turning on
or off conditions
●When all of the following conditions
are fulfilled, the high beams will be
automatically turned on (after approxi-
mately 1 second):
• Vehicle speed is above approximately
30 km/h (19 mph) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with
headlights or tail lights turned on.
• There are few streetlights on the road
ahead.
●If any of the following conditions are
fulfilled, the high beams will be auto-
matically turned off:
• Vehicle speed drops below approxi-
mately 25 km/h (16 mph).
• The area ahead of the vehicle is not
dark.
• Vehicles ahead have headlights or tail
lights turned on.
• There are many streetlights on the
road ahead.
■Front camera detection information
●The high beams may not be automati-
cally turned off in the following situa-
tions:
• When oncoming vehicles suddenly
appear from a curve
• When the vehicle is cut in front of by
another vehicle
• When vehicles ahead are hidden from
sight due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear from the faraway lane on a wide road
• When vehicles ahead have no lights
●The high beams may be turned off if a
vehicle ahead that is using fog lights
without using the headlights is
detected.
●House lights, street lights, traffic sig-
nals, and illuminated billboards or
signs may cause the high beams to
switch to the low beams, or the low
beams to remain on.
●The following factors may affect the
amount of time taken to turn the high
beams on or off:
• The brightness of headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehi-
cles ahead
• When a vehicle ahead only has oper-
ational lights on one side
• When a vehicle ahead is a two-
wheeled vehicle
• The condition of the road (gradient,
curve, condition of the road surface
etc.)
• The number of passengers and
amount of luggage
●The high beams may be turned on or
off when the driver does not expect it.
●Bicycles or similar objects may not be
detected.
●In the situations shown below, the
system may not be able to accurately
detect surrounding brightness levels.
This may cause the low beams to
remain on or the high beams to cause
problems for pedestrians, vehicles
ahead or other parties. In these
cases, manually switch between the
high and low beams.
• In bad weather (rain, snow, fog, sand-
storms, etc.)
• The windshield is obscured by fog,
mist, ice, dirt, etc.
• The windshield is cracked or dam-
aged
• The front camera is deformed or dirty
• When the temperature of the front
camera is extremely high
• Surrounding brightness levels are

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 this 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 always be able to achieve the same level of perfor-
mance. Read the following conditions care-fully. Do not overly 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 may 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 pre-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-collision 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 turned 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 driver 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-collision system can be
enabled/disabled on the screen
( P.186) of the multi-information
display.
The system is automatically 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 displayed 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 such 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

■Cancelation of the pre-collision
braking
If either of the following occur while the pre-collision braking function is operat-
ing, 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 follow-ing, the system may determine that
there is a possibility of a frontal colli- sion and operate.• When passing a detectable object,
etc. • When changing lanes while overtak-ing a detectable object, etc.
• When approaching a detectable object in an adjacent lane or on the roadside, such as when changing the
course of travel or driving on a wind- ing road
• When rapidly closing on a detectable object, etc.• When approaching objects on the
roadside, such as detectable objects,
guardrails, utility poles, trees, or walls
• When there is a detectable object or other object by the roadside at the entrance of a curve
• When there are patterns or paint in front of your vehicle that may be mis-
taken for a detectable object • When the front of your vehicle is hit by water, snow, dust, etc.
• When overtaking a detectable object that is changing lanes or making a right/left turn
• When passing a detectable object in an oncoming lane that is stopped to
make a right/left turn
• When a detectable object approaches
very close and then stops before entering the path of your vehicle• If the front of your vehicle is raised or
lowered, such as when on an uneven or undulating road surface• When driving on a road surrounded by
a structure, such as in a tunnel or on an iron bridge
