QBreaking in your new Toyota
To extend the life of the vehicle, observing the following precautions is recom-
mended:
OFor the first 300 km (200 miles):
Avoid sudden stops.
OFor the first 1000 km (600 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive at a constant speed for extended periods.
QOperating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 714)
QFor efficient use
OShift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be gen-
erated. The hybrid battery (traction battery) will discharge, requiring unnec-
essary engine power to charge.
ODrive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the electric motor (traction motor)
without having to use gasoline engine power.
OAvoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
OShift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not charge. Leav-
ing the shift position in the N position for an extended period of time may
discharge the hybrid battery (traction battery). The vehicle cannot run if the
hybrid battery (traction battery) is discharged.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
Q 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.
Q When driving the vehicle
O 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 ac cident.
• 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.
O The driver should pay extra attention to pedestrians when the vehicle is
powered only by the electric motor (traction motor). As there i s no engine
noise, the pedestrians may misjudge the vehicle’s movement. Eve n
though the vehicle is equipped with the vehicle proximity notif ication sys-
tem, drive with care as pedestrians in the vicinity may still n ot notice the
vehicle if the surrounding area is noisy.
O Do not drive the vehicle over or stop the vehicle near flammable materials
such as leaves, paper or rags.
The exhaust system and exhaust gases can be extremely hot. Thes e hot
parts may cause a fire if there is any flammable material nearb y.
O During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or bra king 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. 647

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
Q When driving the vehicle
O Use engine braking (shift position B instead of shift position D) 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. 3 3 0 )
O 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.
O Always check that all passengers’ arms, head or other parts of their body
are not outside the vehicle.
O Do not drive across river crossings or through other bodies of water.
This may cause electric/electronic components to short circuit, damage
the hybrid system or cause other serious damage to the vehicle.
Q When driving on slippery road surfaces
O Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
O Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid, resulting in an accident.
O After driving through a puddle, 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 sid e are wet
and not functioning properly, steering control may be affected.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
Q When shifting the shift position
O Do not let the vehicle roll backward while a forward driving position is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
O Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
O Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
O Do not shift the shift position to a driving position while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
O Changing the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hyb rid system
disengaged.
O Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any position other than P or N m ay lead to
unexpected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
Also, when the shift position is in N, the shift position may n ot be able to be
changed to the intended shift position.
After changing the shift position, make sure to confirm the cur rent shift
position displayed on the shift position indicator inside the m eter.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
Q If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Toyo ta
retailer or Toyota authorized repairer, or any reliable repaire r 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 th e brake pads
and/or those of the brake discs are exceeded.
Q When the vehicle is stopped
O Do not depress the accelerator pedal unnecessarily.
If the shift position is in any position other than P or N, the vehicle may
accelerate suddenly and unexpectedly, causing an accident.
O In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indic ator is
illuminated, and apply the parking brake as necessary.
O 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.
O Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped m ay cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.
