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)

Remote Air Conditioning System
■Using the Remote Air Conditioning System effectively
Efficiency can be increased by using the system in conjunction with the
Solar Ventilation System. ( P. 282)
: If equipped
The Remote Air Conditioning System uses electrical energy stored
in the hybrid battery (traction batt ery) and allows the air conditioning
to be operated by remote control.
■ Activating the Remote Air Conditioning System
Press and hold the to
operate the Remote Air Condi-
tioning System.
• The system will shut off if a door is opened.
• The system can be stopped
by pressing the
twice.

PRIUS_U (OM47668U) U.S.A.
■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.
● The air conditioning is not set to MAX HOT.
■ 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.
● Check the temperature setting of the air conditioning system. 
The Remote Air Conditioning System will operate in accordance with the
temperature settings of the air conditioning system.
■ Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
● About 3 minutes have passed since operation began
● Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (trac-
tion battery) drops to low. ( P. 188)
■ Conditions affecting operation
The system may not start in the following situations:
● The charge level of the hybrid battery (traction battery) is low (P. 188)
● The air conditioning temperature is set at a high level

408 4-1. Maintenance and care
PRIUS_U (OM47668U) U.S.A.
■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 apply
water. Excellent results are obtained by keeping the carpet as dry as possi-
ble.
■ 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.
CAUTION
■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, or 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. 115) 
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.

■Tire types
1 Summer tiresSummer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow-covered or icy ro ads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( P. 261)

If the vehicle becomes stuck
CAUTION
■When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the sur-
rounding area is clear, to avoid striking other vehicles, objects or persons.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
■ When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed. 
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt, or snow.
Stop the hybrid system. Set t he parking brake and push the
“P” position switch.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material to help provide
traction under the tires.
Restart the hybrid system.
Shift the shift lever to “D” or “R” and carefully apply the
accelerator to free the vehicle.STEP1
