NOTICE
■To prevent 12-volt battery discharge
●Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods of time without the hybrid system on.
● If is displayed on the multi-information display, the “POWER”
switch is not off. Exit the vehicle after turning the “POWER” switch off.
● Do not stop the hybrid system when the shift lever is in a position other
than P. If the hybrid system is stopped in another shift lever position, the
“POWER” switch will not be turned off but instead be turned to ACCES-
SORY mode. If the vehicle is left in ACCESSORY mode, 12-volt battery
discharge may occur.
■ When starting the hybrid system
●Do not depress the accelerator pedal unnecessarily.
● If the hybrid system becomes difficult to start, have your vehicle checked
by your Toyota dealer immediately.
■ Symptoms indicating a malfunction with the “POWER” switch
If the “POWER” switch seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Con-
tact your Toyota dealer immediately.

◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆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
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Helps to prevent the vehicle from rolling backward when starting on
an incline
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
Driving assist systems
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

2624-6. Using the driving support systems
PRIUS c_U (OM52F96U)
The slip indicator light will flash
while the TRAC/VSC/ABS sys-
tems are operating.
If the vehicle gets stuck in mud, dirt or snow, the TRAC system may
reduce power from the hybrid syst em to the wheels. Pressing to
turn the system off may make it eas ier for you to rock the vehicle in
order to free it.
To turn the TRAC system off,
quickly press and release .
The “TRAC OFF” will be shown on
the multi-information display.
Press again to turn the system
back on.
■ Turning off both TRAC and VSC systems
To turn the TRAC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The VSC OFF indicator light will come on and the “TRAC OFF” will be shown
on the multi-information display.
Press again to turn the systems back on.
■ When the message is displayed on th e multi-information display show-
ing that TRAC has been disable d even if has not been pressed

Sounds and vibrations caused by th e 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

Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
●The shift lever is in a position other than P or N (when starting off forward/
backward on an upward incline).
● The vehicle is stopped.
● The accelerator pedal is not depressed.
● The parking brake is not engaged.
■ Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
● The shift lever is moved to P or N.
● The accelerator pedal is depressed.
● The parking brake is engaged.
● Approximately 2 seconds elapse after the brake pedal is released.

WARNING
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick 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, especially 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 may not operat e effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control
●Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended 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.

WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a dif-
ferent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pre ssure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle’s hand ling and stopping ability.
Please note that the TPMS (tire pres sure warning system) is not a sub-
stitute for proper ti re maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumina tion of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicator to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) malfunc-
tion indicator is combined with the lo w tire pressure telltale (tire pressure
warning light). When the system dete cts a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue up on subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tire pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
