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 the engine compartment when the brak e pedal
is operated.
● Motor sound of the brake system heard from the front part of th e vehicle
when the driver’s door is opened.
● Operating sound heard from the engine compartment when one or t wo min-
utes passed after the stop of the hybrid system.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) 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 s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s 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.
■ Electric power steering system wa rning light (warning buzzer)

■ 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 power 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 wh en vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases.

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (suc h as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or s lick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, espe cially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRAC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and p ower may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start ass ist control may
not operate effectively on steep inclines and roads covered wit h ice.
● Unlike the parking brake, hill-start assist control is not inte nded to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the TRAC/ABS/VSC are activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stabilit y and driving
force, do not turn the TRAC/VSC systems off unless necessary.

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 (heating/coo ling) will be minimized, improving
the fuel economy. ( P. 203)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the needle of H ybrid
System Indicator within Eco area. ( P. 110)
◆Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift lever to P when parking. When using
the N, there is no positive effe ct on fuel consumption. In the N, the
gasoline engine operates but e lectricity cannot be generated. A lso,
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 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.
◆When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
Hybrid vehicle driving tips
For economical and ecological dri ving, pay attention to the fol-
lowing points:

2724-7. Driving tips
PRIUS c_U
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel economy. Check traffic re ports
before leaving and avoid delays as much as possible. When drivi ng
in a traffic jam, gently release the brake pedal to allow the v ehicle to
move forward slightly while avoiding overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.
◆Highway driving
Control and maintain the vehicle at a constant speed. Before st op-
ping at a toll booth or similar, allow plenty of time to releas e the
accelerator and gently apply the brakes. A greater amount of el ec-
trical energy can be regenerated when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient tempe rature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system and reduce fuel consumption as well.
In winter: Because the gasolin e engine will not automatically cut out
until it and the interior of the vehicle are warm, it will cons ume fuel.
Also, fuel consumption can be improved by avoiding overuse of t he
heater.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Impr oper
tire inflation pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to poor fuel economy. Use tires that are app ro-
priate for the season.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.

●Use fluids that are appropriate t o the prevailing outside tempera-
tures. • Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspect the condition of the 12-volt bat-
tery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that cha ins match
the size of the tires.
Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is fr ozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to p revent it from freezing.
● To ensure proper operation of the 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 ic e or snow that may have accu-
mulated on the exterior lights, vehicle's roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to roa d con-
ditions.
Winter driving tips
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a ma n-
ner appropriate to the prevailing weather conditions.
