Driving
■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-

4-6.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.

Use fluids that are appropriate to
the prevailing outside tempera-
tures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
 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
Winter driving tips
Carry out the necessary prepa-
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
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.

5-1. Using the air conditioning system and defogger
Interior features
windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recir-culated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after closing the windows, it is recom-
mended that the air intake mode be set to outside air mode and the fan speed to any setting except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in pre-
venting dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air tempera-
ture is high.
●Outside/recirculated air mode may
automatically switch depending on the temperature setting or the inside tem-perature.
■Operation of the air conditioning
system in Eco drive mode
●In Eco drive mode, the air conditioning
system is controlled as follows to pri- oritize fuel efficiency:• Engine speed and compressor opera-
tion controlled to restrict heating/cool- ing capacity• Fan speed restricted when automatic
mode is selected
●To improve air conditioning perfor-
mance, perform the following opera- tions:• Adjust the fan speed
• Turn off Eco drive mode ( P.275)
●Even when the drive mode is set to
Eco drive mode, the air conditioning eco mode can be turned off by press-ing the “FAST/ECO” switch. ( P.290)
■When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not operate even when “A/C” switch is
pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condition-
ing system to the outside air mode.
●During use, various odors from inside
and outside the vehicle may enter into and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
●To reduce potential odors from occur-
ring: • It is recommended that the air condi-tioning system be set to outside air
mode prior to turning the vehicle off. • The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
●When parking, the system automati-cally switches to outside air mode to encourage better air circulation
throughout the vehicle, helping to reduce odors that occur when starting the vehicle.

■Customization
Some functions can be customized. ( P.431)
WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger
switch during cool air operation in extremely humid weather. The differ-ence between the temperature of the
outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your
vision.
■When the outside rear view mir-
ror defoggers are operating
Do not touch the outside rear view mirror surfaces, as they can become
very hot and burn you.

that indicate service is needed. Some important clues are:
●Engine misses (misfire), stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-ever, water dripping from the air con-
ditioning system after use is normal.)
●Change in exhaust sound (This may
indicate a dangerous carbon monox- ide leak. Drive with the windows open and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire
squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches the floor, vehicle pulls to one
side when braking
