Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■Enhanced VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control)
Maintains drive power and prevents the front wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
P. 243
■ EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
■Pre-Collision System (if equipped)
P. 249

■Conditions that may trigger the system even if there is no danger of
collision
● When there is an object by the roadside at the entrance to a curve
● When passing an oncoming vehicle on a curve
● When driving over a narrow iron bridge
● When there is a metal object on the road surface
● When driving on an uneven road surface
● When passing an oncoming vehicle on a left-turn
● When your vehicle rapidly closes on the vehicle in front
When the system is activated in the situations described above there is also
a possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
restricted position, stop the vehicle in a safe place, release the seat belt and
refasten.
■ When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. ( P. 508)

CAUTION
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-
ment.
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
●Do not place cargo or luggage in or on the following locations as the
item may get under the brake or accelerator pedal and prevent the
pedals from being depressed properly , block the driver’s vision, or hit
the driver or passengers, causing an accident.
• Driver’s feet
• Front passenger or rear seats (when stacking items)
• Luggage cover (if equipped)
• Instrument panel
• Dashboard
• Auxiliary box or tray that has no lid
●Secure all items in the occupant compartment, as they may shift and
injure someone during sudden braking, sudden swerving or an acci-
dent.
●Never allow anyone to ride in the luggage compartment. It is not
designed for passengers. They should ride in their seats with their seat
belts properly fastened. Otherwise, th ey are much more likely to suffer
death or serious injury, in the event of sudden braking, sudden swerv-
ing or an accident.

■Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
● To ensure proper operation of th e climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
● Remove any ice that has accumu lated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.
■ When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
■ When parking the vehicle
Park the vehicle and push the “P” position switch without setting
the parking brake. The parking brake may freeze up, preventing
it from being released. If necessa ry block the wheels to prevent
inadvertent sliding or creeping.

• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
CAUTION
■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, blocking
your vision.
■ Plasmacluster™
Do not disassemble or repair the system because it contains high voltage
parts. Call your Toyota dealer if the system needs repair.
NOTICE
■To prevent 12 volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is not operating.
■ To prevent damage to the Plasmacluster™
Do not insert anything into the driver’s side vent, attach anything to it, or use
sprays around the driver’s side vent. These things may cause the system no
to work properly.
