2664-6. Using the driving support systems
PRIUS c_U (OM52J11U)■
Sounds and vibrations caused by the ABS, brake assist, TRAC, VSC and
hill-start assist control systems
Any of the following conditions may occur when the above systems are oper-
ating. None of these indicates that a malfunction has occurred.
●Vibrations may be felt through the vehicle body and steering.
● A motor sound may be heard after the vehicle comes to a stop.
● The brake pedal may pulsate slightly after the ABS is activated.
● The brake pedal may move down slightly after the ABS is activated.
■ ECB operating sound
ECB operating sound may be heard in the following cases, but it does not
indicate that a malfunction has occurred.
●Operating sound heard from engine compartment when the brake pedal is
operated.
● Motor sound of the brake system heard from the front part of the vehicle
when the driver’s door is opened.
● Operating sound heard from the engine compartment when one or two min-
utes passed after the stop of the hybrid system.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the engine switch is turned to the “LOCK” position (vehicles without a
smart key system) or the “POWER” switch is turned off (vehicles with a
smart key system)
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases

4-7. 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 (h eating/cooling) will be minimized, improving
the fuel economy. ( →P. 374)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the needle of Hybrid
System Indicator within Eco area. ( →P. 104)
◆Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift le ver to P when parking. When using
the N, there is no positive effect on fuel consumption. In the N, the
gasoline engine operates but elec tricity cannot be generated. Also,
when using the air conditioning s ystem, etc., the hybrid battery
(traction battery) power is consumed.
◆Accelerator pedal/brake pedal operation
● Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerati on 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 consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.

■ Customization
The air conditioning control of Eco drive mode can be changed to the same
setting as that used in normal drive mode.
(Customizable features →P. 557)
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.
■ When the outside rear view mirr or defoggers are on (if equipped)
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
NOTICE
■ To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
● 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.

4047-1. Maintenance and care
PRIUS c_U (OM52J11U)
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle's interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
WARNING
■Water in the vehicle
● Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air vents, and in the luggage compartment.
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
(→P. 41)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
■ Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver's view and leading to an accident,
resulting in death or serious injury.
