4-1. Before driving
WARNING
●The driver should pay extra atten- tion to pedestrians when the vehicle
is powered only by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s move- ment.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These 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 brak-
ing control, however, power assist to the steering will be lost. This will make it more difficult to steer
smoothly, so you should pull over and stop the 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. 3 6 6
●Use engine braking (shift position
B) 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.181)
●Do not adjust 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.
■When driving on slippery road surfaces
●Sudden braking, acceleration and
steering may cause tire slippage and reduce your ability to control the vehicle.
●Sudden acceleration, engine brak-ing due to shifting, or changes in
engine speed could cause the vehi- cle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that the brakes are func-
tioning properly. Wet brake pads may prevent the brakes from func-tioning properly. If the brakes on
only one side are wet and not func- tioning properly, steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward
while a forward driving position is selected, or roll forward while the shift lever is in R.
Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
●Do not shift the shift lever to a driv-ing position while the vehicle is moving backward.
Doing so can damage the transmis- sion and may result in a loss of vehicle control.

Driving
WARNING
●Moving the shift lever to N while the vehicle is moving will disengage the
hybrid system. Engine braking is not available with the hybrid system disengaged.
●Be careful not to shift the shift lever with the accelerator pedal
depressed. Shifting the shift lever to any positions other than P or N may lead to unexpected rapid accelera-
tion of the vehicle that may cause an accident and result in death or serious injury.
■If you hear a squealing or scrap-ing noise (brake pad wear indica-
tors)
Have the brake pads checked and replaced by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
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 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 acci-dents 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 over-
heat, 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 follow-
ing:
• Gas may leak from a cigarette
lighter or spray can, and may lead 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, caus-
ing the contents to spray over 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 fresh-
eners on the instrument panel or dashboard. Adhesive discs or con-tainers may act as lenses, causing
a fire in the vehicle.

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.
