721-4. Hybrid system
■If “Proximity Notification Sys-
tem Malfunction Visit Your
Dealer” is displayed on the
multi-information display
The system may be malfunctioning.
Have the vehicle inspected by your
Toyota dealer.
*: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “MULTIME-
DIA OWNER’S MANUAL”.
■Predictive deceleration support
●When the vehicle approaches to
predictive deceleration support
points registered in the navigation
system, the zone of Eco accelera-
tion ( ) of the ECO Accelerator
Guidance ( P.99) on the
multi-information display will be
turned off to encourage the driver
to reduce excessive acceleration.
Example: 7-inch display
●The engine braking force will be
increased according to the driving conditions to more efficiently
charge the hybrid battery (traction
battery) after the accelerator pedal
is released.
■Predictive SOC* control
The following types of control are
performed based on data such as
road and traffic information during
route guidance by the navigation
system to help ensure that the vehi-
cle efficiently uses electricity.
●When there is a long downhill
slope along the r oute, the system
reduces the hybrid battery (trac-
tion battery) leve l before reaching
the slope to help ensure charging
capacity for regenerative braking
while traveling downhill.
●When traffic congestion is pre-
dicted along the route, the system
helps ensure a certain battery
level before reaching congested
roads to reduce the frequency of
starting the engin e to charge the
hybrid battery (traction battery)
due to low battery levels.
*: SOC means state of charge

tion system)

Driving
When the shift lever is shifted
from P or R to forward drive
shift position such as D
*.
When the system operates, a
message appears on the
multi-information display. Read
the message and follow the
instruction.
*: Depending on the situation, the shift position may not be
changed.
■When starting off on a uphill
The hill-start assis t control will acti-
vate. ( P.311)
■For fuel-efficient driving
Keep in mind that hybrid vehicles
are similar to conventional vehicles,
and it is necessary to refrain from
activities such as sudden accelera-
tion. ( P.318)
■Driving in the rain
●Drive carefully whe n it is raining,
because visibility will be reduced,
the windows may become
fogged-up, and the road will be
slippery.
●Drive carefully whe n it starts to
rain, because the road surface will
be especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■ECO Accelerator Guidance
(  P.99, 110)
It is easier to drive in an Eco-friendly
manner by driving while referring to
the ECO Accelerator Guidance dis-
play. Also, by using the ECO Accel-
erator Guidance it is easier to
increase the “Eco Score” evaluation.
●When starting off: While staying
within the ECO Accelerator Guid-
ance range, gradually depress the
accelerator pedal and accelerate
to the desired speed. If excessive
acceleration is avoided, the “Start”
score will increase.
●When driving: After accelerating to
the desired speed, release the
accelerator pedal and drive at a
stable speed within the ECO
Accelerator Guidance range. By
keeping the vehicle within the
ECO Accelerator Guidance range,
the “Cruise” sco re will increase.
●When stopping: When stopping
the vehicle, early releasing the
accelerator pedal will cause the
“Stop” score to increase.
■Restraining the hybrid system
output (Brake Override System)
●When the accelera tor and brake
pedals are depressed at the same
time, the hybrid system output
may be restrained.
●A warning message is displayed
on the multi-information display
while the system is operating.
■Drive-Start Control (DSC)
When the TRAC is turned off
(  P.312), sudden start restraint
control also does not operate. If
your vehicle have trouble escaping
from the mud or fr esh snow due to
sudden start restraint control opera-
tion, deactivate TRAC ( P.312) so
that the vehicle may become able to
escape from the mud or fresh snow.
Also, sudden start restraint control
will not operate in the following con-
ditions:
●When Trail Mode is turned on
(AWD models)
■Breaking in your new Toyota
To extend the life of the vehicle,
observing the following precautions
is recommended:
●For the first 200 miles (300 km):

2344-4. Refueling
4-4.Refueling
Close all the doors and win-
dows, and turn the power
switch off.
 Confirm the type of fuel.
■Fuel types
 P. 4 9 8
■Fuel tank opening for unleaded
gasoline
To help prevent incorrect fueling,
your vehicle has a fuel tank opening
that only accommodates the spe-
cial nozzle on unle aded fuel pumps.
Opening the fuel tank
cap
The fuel tank of your vehicle
has a special structure,
which requires a reduction
in fuel tank pressure before
refueling. After the opener
switch has been pressed, it
will take several seconds
until the vehicle is ready for
refueling.
Before refueling the vehi-
cle
WARNING
■When refueling the vehicle
Observe the following precautions
while refueling the vehicle. Failure
to do so may result in death or
serious injury.
●After exiting the vehicle and
before opening the fuel door,
touch an unpainted metal sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing from static electricity can
cause fuel vapors to ignite while
refueling.
●Always hold the grips on the
fuel tank cap and turn it slowly
to remove it.
A whooshing sound may be
heard when the f uel tank cap is
loosened. Wait until the sound
cannot be heard before fully
removing the cap. In hot
weather, pressurized fuel may
spray out of the filler neck and
cause injury.
●Do not allow anyone that has
not discharged static electricity
from their body to come close to
an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that
are harmful if inhaled.
●Do not smoke while refueling
the vehicle.
Doing so may cause the fuel to
ignite and cause a fire.
●Do not return to the vehicle or
touch any person or object that
is statically charged.
This may cause static electricity
to build up, resulting in a possi-
ble ignition hazard.
■When refueling
Observe the following precautions
to prevent fuel overflowing from
the fuel tank:
●Securely insert the fuel nozzle
into the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.

1Press the switch to open the
fuel filler door.
The fuel filler door will open within
about 10 seconds of the switch
being pressed. Before refueling is
possible, a message will be shown
on the multi-information display to
indicate the progress of the fuel
filler door opener.
2Turn the fuel tank cap slowly
to remove it and hang it on
the back of the fuel filler door.
■If the fuel filler door cannot be
opened
 P.476
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
WARNING
●Do not top off the fuel tank.
NOTICE
■Refueling
●Finish refueling within 30 min-
utes. If more than 30 minutes
passes, the internal valve
closes. In this condition, fuel
may spill out if y ou continue to
refuel the vehicle. About 5 min-
utes after the valve is closed, a
message “Close Fuel Lid” will
appear on the multi-information
display. To refuel the vehicle
again, tighten th e fuel tank cap
and close the fuel filler door,
and then press the opener
switch again.
●Make sure that the fuel filler
door lock is not pushed by the
fuel nozzle boot, etc. If the lock
is held, the internal valve closes
and fuel may overflow. To pre-
vent it, press the fuel filler door
opener switch again.
●Do not spill fuel during refueling.
Doing so may damage the vehi-
cle, such as causing the emis-
sion control system to operate
abnormally or damaging fuel
system components or the vehi-
cle’s painted surface.

WARNING
■When replacing the fuel tank
cap
Do not use anything but a genu-
ine Toyota fuel tank cap designed
for your vehicle. Doing so may
cause a fire or other incident
which may result in death or seri-
ous injury.
