CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
● Vehicles that cut in suddenly
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane
■ Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively:
● Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by your Toy-
ota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
● Do not modify or paint the sensor and grille cover.

■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.
● Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
● Remove snow or mud from the bottom of your shoes before
getting in the vehicle.
■ When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to
road conditions.
■ When parking the vehicle
Park the vehicle and shift the shift position to P and block the
wheel under the vehicle without setting the parking brake. The
parking brake may freeze up, preventing it from being released.
If necessary, block the wheels to prevent inadvertent sliding or
creeping.

PRIUS PHV_OM_OM47818U_(U)
■Operating conditions
The system will only operate if all of the following conditions are met:
● The shift position is in P.
● The “POWER” switch is OFF.
● All doors are closed.
● The hood is closed.
● The brake pedal is not being depressed.
■ When leaving the vehicle
● Check that the headlights are switched to either off or “AUTO”.
● Check that the wiper switch is turned off.
● Check that all windows are closed.
■ Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
● About 10 minutes have passed since operation began
● Any one of the operating conditions is not met
● There is only a slight difference between the air conditioning set temper-
ature and the inside temperature.
The system may also shut off if the charge level of the hybrid battery (trac-
tion battery) drops to low. ( P. 60)
■ Conditions affecting operation
The system may not start in the following situations:
● The charge level of the hybrid battery (traction battery) is low (P. 60)
● The air conditioning temperature is set at a high level or outside tempera-
ture is low
● When the hybrid system is cool (for example, after being left for a long
time in low temperatures)

■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking
efficiency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage painted
surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious proble\
m.
