NOTICE
■When the rear window is dry
Do not use the wiper, as it may damage the rear window.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
■ To prevent 12-volt battery discharge
Do not leave the wiper on longer than necessary when the hybrid system is
off.

■Operational conditions
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a detected object is high.
Each function is operational at the following speed
●Pre-collision warning
● Pre-collision brake assist
● Pre-collision braking
The system may not operate in the following situations:
● If a 12-volt battery terminal has been disconnected and reconnected and
then the vehicle has not been driven for a certain amount of ti me
● If the shift position is in R
● When the VSC OFF indicator is illuminated (only the pre-collisi on warning
function will be operational)

■Sensor detection range
The detection range of the Parking Support Brake function diffe rs from the
detection range of the intuitive parking assist. ( P. 362)
Therefore, even if the intuitive parking assist detects an obst acle and pro-
vides a warning, the Parking Support Brake function may not sta rt operating.
■ System operation
When the vehicle is stopped by system operation, the Parking Support Brake
function stops and the PKSB OFF indicator illuminates.
■ System recovery
When the Parking Support Brake function is stopped by system op eration
and you would like to resume operation, either turn the Parking Support
Brake function on again ( P. 372), or turn the power switch off and then back
on. Furthermore, when the vehicle moves with an obstacle no lon ger in the
traveling direction of the vehicle, or when the traveling direc tion of the vehicle
changes (such as when switching from moving forward to backing up, and
vice versa), system operation automatically resumes.
■ Obstacles not detected by the sensors
The following obstacles may not be detected by the sensors.
●Objects such as people, cloth and snow, that are difficult for sonic waves to
reflect off of. (In particular, people may also not be detected depending on
the type of clothing they are wearing.)
● Objects not perpendicular with the ground, objects not at a rig ht angle to the
traveling direction of the vehicle, uneven objects or waving objects
● Low objects
● Thin objects such as wires, fences, ropes and signposts
● Objects that are extremely close to the bumper
■ Situations in which the syst em may not operate properly
P. 365
■ Situations in which the system may operate even if there is no possibil-
ity of a collision
P. 366
■ In the unlikely event that the Parking Support Brake function m istakenly
operates at a crossing or elsewhere
Even in the unlikely event that the Parking Support Brake funct ion mistakenly
operates at a crossing or elsewhere, brake control is canceled after approxi-
mately 2 seconds, allowing you to proceed forward and leave the area. Fur-
thermore, brake control is also canceled when the brake pedal i s depressed.
Depressing the accelerator pedal again allows you to proceed forward and
leave the area.
■ When removing and instal ling the 12-volt battery
The system needs to be initialized.
The system can be initialized by driving the vehicle straight a head for 5 sec-
onds or more at a speed of approximately 22 mph (35 km/h) or hi gher.

MessageSituation/Handling method
The system may be malfunctioning.
 Turn the power switch off and then start the
hybrid system.
Have the vehicle inspected by your Toyota
dealer if the message is displayed again.
There may be a system failure.
Power steering equipment is temporarily overheat-
ing.
Turn the power switch off, wait for a little
while, and then start the hybrid system again.
The hybrid system is not operating.
Start the hybrid system.
Ice, snow, dirt, etc., has adhered to the sensor.
Remove any ice, snow, dirt, etc.
The sensor is frozen.
Once the sensor thaws, the system will return
to normal.
The 12-volt battery has been removed and rein-
stalled.
Drive the vehicle straight ahead for 5 seconds
or more at a speed of approximately 22 mph
(35 km/h) or higher.
The S-APGS switch is operated when the vehicle
speed exceeds 19 mph (30 km/h).
Operate the switch when the vehicle speed is
approximately 19 mph (30 km/h) or less.
Assist control is started while the steering wheel is
held.
Rest your hands on the steering wheel with-
out applying any force. Assist control will
start.

4-6. Driving tips
Hybrid vehicle driving tips
◆Using Eco drive mode
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/coo ling) will be minimized, improving
the fuel economy. ( P. 342)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the Hybrid Syst em
Indicator within Eco area. ( P. 129)
◆Shift position operation
Shift the shift position to D when stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift position to P when parkin g. When
using the N, there is no positiv e effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener -
ated. Also, when using the air conditioning system, etc., the h ybrid
battery (traction batt ery) power is consumed.
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerat ion and deceleration will make
more effective use of the electric motor (traction motor) witho ut
having to use gaso line engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (tracti on battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
For economical and ecological dri ving, pay attention to the fol-
lowing points:

WARNING
■To prevent the windshield from fogging up
● Do not use
during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rea r view mirror
defoggers are on.
NOTICE
■ To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessa ry when the
hybrid system is off.
■ When repairing/replacing parts of the air conditioning system
Have repair/replacement performed by your Toyota dealer. When a part of
the air conditioning system, such as the evaporator, is to be replaced, it
must be replaced with a new one.
■ Air outlets
The air outlets become hot when used for heating. Therefore, us e caution
and adjust the air outlets accordingly.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
