1904-1. Before driving
Owners Manual_USA_M0C043_en
WARNING
■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
braking due to shifting, or
changes in engine speed could
cause the vehicle to skid.
●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 prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.
■When shifting the shift lever
●Do not let the vehicle roll back-
ward while a forward driving
position is selected, or roll for-
ward while the shift lever is in R.
Doing so may result in an acci-
dent or damage to the vehicle.
●Do not shift the shift lever to P
while the vehicle is moving.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to R
while the vehicle is moving for-
ward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to a
driving position while the vehicle
is moving backward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Moving the shift lever to N while
the vehicle is moving will disen-
gage 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 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 indicators)
Have the brake pads checked and
replaced by your Toyota dealer, 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 accelerate suddenly and
unexpectedly, causing an acci-
dent.
●In order to prevent accidents
due to the vehic le rolling away,
always keep depressing the
brake pedal while stopped with
the “READY” indicator is illumi-
nated, and apply the parking
brake as necessary.

3964-6. Driving tips
Owners Manual_USA_M0C043_en
4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. (P.366)
The Eco-friendly driving is pos-
sible by keeping the indicate of
Hybrid System Indicator within
Eco area. ( P.99)
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. When using the air condi-
tioning system, etc., the hybrid
battery (traction battery) power
is consumed. 
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration 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 (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery 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
deceleration, as well as long
waits at traffic lights, will lead to
bad fuel economy. Check traffic
reports before leaving and avoid
delays as much as possible.
When driving in a traffic jam,
gently release the brake pedal
to allow the vehicle to move for-
ward slightly while avoiding
Hybrid Electric Vehi-
cle driving tips

ical driving, pay attention to
the following points:
Using Eco drive mode
Use of Hybrid System
Indicator
