Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■ Using Eco drive mode
P. 174
■Use of Hybrid System Indicator
By keeping Hybrid System Indicator within Eco area, more Eco-friendly
driving may be possible. ( P. 195)
■When braking the vehicle
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
■Delays
Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fuel consumption. Check traffic reports before
leaving and avoid delays as much as possible. When encountering a
delay, gently release the brake pedal to allow the vehicle to move for-
ward slightly while avoiding overuse of the accelerator pedal. Doing so
can help control excessive gasoline consumption.
■Highway driving
Control your speed and keep at a constant speed. Also, before stop-
ping at a toll booth or similar, allow plenty of time to release the acceler-
ator and gently apply the brakes. A greater amount of electrical energy
can be retained when slowing down.
■Air conditioning
Use the air conditioning only when necessary. Doing so can help con-
trol excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode. Doing
so will help to reduce the burden on the air conditioning and reduce fuel
consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until the gasoline engine and the interior of the vehicle are warm, it will
consume fuel. Also, fuel consumption can be improved by avoiding
overuse of the heater.

Before driving
■
Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use on dry
roads can lead to poor fuel consumption. Use a tire that is appropriate
for the season.
■Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid car-
rying unnecessary luggage. Installing a large roof rack can also cause
poor fuel consumption.
■Warming up before driving
Since the gasoline engine starts up and cuts out automatically when
cold, warming up the engine is unnecessary. Moreover, frequently driv-
ing short distances will cause the engine to repeatedly warm up, which
can lead to poor fuel consumption.

When driving
CAUTION
■
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid sys-
tem operating. This prevents the vehicle from creeping.
■ 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 brake
pedal will result in sudden acceleration that may lead to an accident
that could result in death or serious injury.
• 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 the vehicle only slightly. This allows you to depress the brake and acceler-
ator 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 vehicle is
powered only by the electric motor (traction motor). Because there is no
engine noise, the pedestrians may misjudge the vehicle’s movement.
● Do not drive the vehicle over or st op 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.
● Do not let the vehicle roll backward while the shift lever is in a driving posi-
tion, or roll forward while the shift lever is in R.
Doing so may result in an accident or damage to the vehicle.
● If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by your Toyota dealer
immediately.
● Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle\
control.

152 2-1. Driving procedures
CAUTION
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● 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 dis-
engaged.
● 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,
but the power assist to these systems will be lost. This will make it more
difficult to steer and brake, so you should pull over and stop the vehicle as
soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 486
● Use engine braking (shift position B) to maintain a safe speed when driv-
ing down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 174)
● 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 that can cause accidents,
resulting in death or serious injury.
● Always check that all passengers' arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.

When driving
CAUTION
■
When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
● Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid, resulting in an accident.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
■ When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
Shifting the shift lever to a gear other than P or N may lead to unexpected
rapid acceleration of the vehicle that may cause an accident and 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 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.

154 2-1. Driving procedures
CAUTION
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any gear other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.
● Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the “READY” indicator is on. Apply the
parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents 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 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, causing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehi-
cle'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.

Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 457)
■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
●Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, etc.
● Lubricant condition of the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
