■Engine speed
On hybrid vehicles, engine speed is precisely controlled in ord er to help
improve fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may dif fer even
when vehicle operation and driving conditions are the same.
■ Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change:
●When stopped, or driving at low speeds (less than 16 mph [25 km/h])
● When the outside temperature has changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
● When “ ” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to your Toyota dealer.
■ Fuel gauge and driving range display
The fuel gauge and driving range display are linked. If the fue l gauge and
driving range display do not update after refueling a small amount, they can
be updated by performing the following procedure:
Stop the vehicle on a level surface.
Wait until the fuel in the fuel tank stabilizes.
Press the ODO/TRIP switch to change the odometer and trip meter display
to the odometer.
Turn the power switch off.
While pressing and holding the ODO/TRIP switch, turn the power switch to
ON mode.
Continue holding the ODO/TRIP switch for approximately 5 seconds.
Release the switch when the odometer begins blinking.
Updating will be complete when the odometer blinks for approximately 5
seconds and then returns to the normal display.
NOTICE
■To prevent damage to the engine and its components
The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 549)

Driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY”
indicator is illuminated. This prevents the vehicle from creepi ng.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the b rake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving t he
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● The driver should pay extra attention to pedestrians when the v ehicle is
powered only by the electric motor (traction motor). As there i s no engine
noise, the pedestrians may misjudge the vehicle’s movement.
● Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. Thes e hot
parts may cause a fire if there is any flammable material nearby.
● During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will m ake it more
difficult to steer smoothly, so you should pull over and stop t he vehicle as
soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 503
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 223)
● Do not adjust the display, the positions of the steering wheel, the seat, or
the inside or outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible.
Rotor damage may result if the pads are not replaced when neede d.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
■ When the vehicle is stopped
● Do not depress the accelerator pedal unnecessarily.
If the shift lever is in any position other than P or N, the vehicle may accel-
erate suddenly and unexpectedly, causing an accident.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indicator is
illuminated, and apply the parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent ac cidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.
■ When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may le ad to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray ov er the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or da shboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.

ventilators

: If equipped
Heated steering wheel and seat heaters heat the side grips of t he
steering wheel and seats, respectively. Seat ventilators mainta in
good ventilation by pulling ai r through the seat upholstery.
WARNING
■To prevent minor burn injuries
Care should be taken to prevent injury if anyone in the followi ng categories
comes in contact with the steering wheel and seats when the hea ter is on:
● Babies, small children, the elderly, the sick and the physically challenged
● Persons with sensitive skin
● Persons who are fatigued
● Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
■ To prevent damage to the seat heaters
Observe the following precautions to prevent the minor burns or overheat-
ing
● Do not cover the seat with a blanket or cushion when using the seat
heater.
● Do not use seat heater more than necessary.
NOTICE
●Do not put heavy objects that have an uneven surface on the sea t and do
not stick sharp objects (needles, nails, etc.) into the seat.
● To prevent battery discharge, do not use the functions when the engine is
not running.

When trouble arises
■If the needle of the engine coolant temperature gauge enters
the red zone or “Engine Coolant Temp High Stop in a Safe
Place See Owner’s Manual” is shown on the multi-information
display
Stop the vehicle in a safe place and turn off the air condition ing sys-
tem, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has
cooled down sufficiently,
inspect the hoses and radiator
core (radiator) for any leaks. Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
If your vehicle overheats
The following may indicate that your vehicle is overheating.
● The needle of the engine coolant temperature gauge ( P. 102)
enters the red zone or a loss of hybrid system power is experi-
enced. (For example, the vehic le speed does not increase.)
● “Engine Coolant Temp High Stop in a Safe Place See Owner’s
Manual” or “Hybrid System Ove rheated Output Power Reduced”
is shown on the multi- information display
● Steam comes out from under the hood.
