■Automatic system cancelation of
hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●The shift lever is shifted to P or N.
●The accelerator pedal is depressed
●The parking brake is engaged
●2 seconds at maximum elapsed after the brake pedal is released
■Sounds and vibrations caused by
the ABS, brake assist, VSC, TRC and hill-start assist control sys-tems
●A sound may be heard from the engine compartment when the brake
pedal is depressed repeatedly, when the hybrid system is started or just after the vehicle begins to move. This
sound does not indicate that a mal- function has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.• Vibrations may be felt through the
vehicle body and steering. • A motor sound may be heard also after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the following cases, but it does not indi-cate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake
pedal is operated.
●Motor sound of the brake system
heard from the front part of the vehicle when the driver’s door is opened.
●Operating sound heard from the engine compartment when one or two minutes passed after the stop of the
hybrid system.
■Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and vibra-
tions may be generated from the brake
system, but this is not a malfunction.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunc- tion.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically re-enabled in the following situations:
●When the power switch is turned off
●If only the TRC system is turned off, the TRC will turn on when vehicle speed increases.
If both the TRC and VSC systems are turned off, automatic re-enabling will not occur when vehicle speed
increases.
■Operating conditions of Active Cor- nering Assist
The system operates when the following
occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate while turning
●The system detects that the vehicle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheating when there is frequent
steering input over an extended period of time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid sys-tem off. The EPS system should return
to normal within 10 minutes.
■Operating conditions of emergency brake signal
When the following conditions are met,
the emergency brake signal will oper-

4-5. Using the driving support systems
ates:
●The emergency flashers are off
●Actual vehicle speed is over 55 km/h (35 mph)
●The system judges from the vehicle deceleration that it is a sudden brak-ing operation.
■Automatic system cancelation of
emergency brake signal
The emergency brake signal will be can- celed in any of the following situations:
●The emergency flashers are turned on.
●The system judges from the vehicle deceleration that is not a sudden brak-
ing operation.
■Secondary Collision Brake operat- ing cancelation
The system operates when the SRS air-
bag sensor detects a collision while the vehicle is in motion.However, the system does not operate
when components are damaged.
■Secondary Collision Brake auto- matic cancelation
The system is automatically canceled in
any of the following situations.
●The vehicle speed drops approxi-
mately 0 km/h (0 mph)
●A certain amount of time elapses
during operation
●The accelerator pedal is depressed a
large amount
WARNING
■The ABS does not operate effec- tively when
●The limits of tire gripping perfor-mance have been exceeded (such as excessively worn tires on a snow
covered road).
●The vehicle hydroplanes while driv-
ing at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a safe distance from
the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with pot-
holes or uneven surfaces
■TRC/VSC may not operate effec-
tively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/VSC system is operating. Drive the vehicle carefully in conditions
where stability and power may be lost.
■Active Cornering Assist does not operate effectively when
●Do not overly rely on Active Corner-
ing Assist. Active Cornering Assist may not operate effectively when accelerating down slopes or driving
on slippery road surfaces.
●When Active Cornering Assist fre-
quently operates, Active Cornering Assist may temporarily stop operat-ing to ensure proper operation of
the brakes, TRC and VSC.
■Hill-start assist control does not
operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.

WARNING
●Unlike the parking brake, hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist con-
trol to hold the vehicle on an incline, as doing so may lead to an acci-dent.
■When the TRC/ABS/VSC is acti-vated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular
care when the indicator light flashes.
■When the TRC/VSC systems are
turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driv-ing force, do not turn the TRC/VSC
systems off unless necessary.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition,
make sure that the tires are inflated to the recommended tire inflation pres-sure level.
The ABS, TRC and VSC systems will not function correctly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer for further information
when replacing tires or wheels.
■Handling of tires and the suspen-
sion
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
■Secondary Collision Brake
Do not rely solely upon the Secondary Collision Brake. This system is
designed to help reduce the possibil- ity of further damage due to a second-ary collision, however, that effect
changes according to various condi- tions. Overly relying on the system may result in death or serious injury.

4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accel-
erator pedal depression amount
can be generated more smoothly
than it is in normal conditions. In
addition, the operation of the air
conditioning system (heating/cool-
ing) will be minimized, improving
the fuel economy. ( P. 2 7 5 )
The Eco-friendly driving is possible
by keeping the indicate of Hybrid
System Indicator within Eco area.
( P.95, 100)
Shift the shift lever to D when
stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift
lever to P when parking. When
using the N, there is no positive
effect on fuel consumption. In the
N, the gasoline engine operates but
electricity cannot be generated.
Also, when using the air condition-
ing system, etc., the hybrid battery
(traction battery) power is con-
sumed.
 Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accelera-
tion and deceleration will make
more effective use of the electric
motor (traction motor) without
having to use gasoline engine
power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (traction
battery) power, resulting in poor
fuel consumption. Battery power
can be restored by driving with
the accelerator pedal slightly
released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical energy
can be regenerated when slowing
down.
Repeated acceleration and decel-
eration, as well as long waits at traf-
fic lights, will lead to bad fuel
economy. Check traffic reports
before leaving and avoid delays as
much as possible. When driving in

4-6. Driving tips
Driving
a traffic jam, gently release the
brake pedal to allow the vehicle to
move forward slightly while avoid-
ing overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.
Control and maintain the vehicle at
a constant speed. Before stopping
at a toll booth or similar, allow
plenty of time to release the accel-
erator and gently apply the brakes.
A greater amount of electrical
energy can be regenerated when
slowing down.
Use the air conditioning only when
necessary. Doing so can help
reduce excessive gasoline con-
sumption.
In summer: When the ambient tem-
perature is high, use the recircu-
lated air mode. Doing so will help to
reduce the burden on the air condi-
tioning system and reduce fuel con-
sumption as well.
In winter: Because the gasoline
engine will not automatically cut out
until it and the interior of the vehicle
are warm, it will consume fuel. Also,
fuel consumption can be improved
by avoiding overuse of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire
inflation pressure can cause poor
fuel economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel econ-
omy. Use tires that are appropriate
for the season.
Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a
large roof rack will also cause poor
fuel economy.
Since the gasoline engine starts up
and cuts out automatically when
cold, warming up the engine is
unnecessary. Moreover, frequently
driving short distances will cause
the engine to repeatedly warm up,
which can lead to excess fuel con-
sumption.

 Have a service technician
inspect the condition of the 12-
volt battery.
 Have the vehicle fitted with four
snow tires or purchase a set of
tire chains for the front tires.
Ensure that all tires are the same size
and brand, and that chains match the
size of the tires.
Perform the following according to

WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents. Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the size specified.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.Failure to do so may result in the vehi-
cle being unable to be driven safely, and may cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains
being used, or 50 km/h (30 mph), whichever is lower.
●Avoid driving on bumpy road sur-faces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-ing operations that cause sudden
engine braking.
●Slow down sufficiently before enter-
ing a curve to ensure that vehicle control is maintained.
●Do not use LTA (Lane Tracing Assist) system. (if equipped)
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer or legitimate tire retailers.This is because the removal and
attachment of snow tires affects the operation of the tire pressure warning valves and transmitters.

the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
 To ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte-
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
 Remove any snow or mud from
the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and shift the
shift lever to P without setting the
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the park-
ing brake, make sure to block the
wheels.
Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
 If the vehicle is parked without
setting the parking brake, con-
firm that the shift lever cannot be
moved out of P*.
*: The shift lever will be locked if it is
attempted to be shifted from P to any
other position without depressing the
brake pedal. If the shift lever can be
shifted from P, there may be a prob-
lem with the shift lock system. Have
the vehicle inspected by any autho-
rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer
or legitimate tire retailers immedi-
ately.
Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.
Side chain (3 mm [0.12 in.] in
diameter)
