ON mode (vehicles with a smart key system) to indicate that a system
check is being performed. They will turn off after the hybrid system is on, or
after a few seconds. There may be a malfunction in a system if the lights
do not come on, or turn off. Have the vehicle inspected by your Toyota
dealer.

WARNING
■ If a safety system warning light does not come on
Should a safety system light such as the ABS or SRS warning light not
come on when you start the hybrid system, this could mean that these sys-
tems are not available to help protect you in an accident, which could r\
esult
in death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will make it more
difficult to steer smoothly, so you should pull over and stop the vehicle as
soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: →P. 467
● Use engine braking (shift position B) to maintain a safe speed when driv-
ing down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( →P. 198)
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers' arms , heads or other parts of their body
are not outside the vehicle.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has h\
igh-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.

PRIUS c_U (OM52J11U)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.
■ When shifting the shift lever
● Do not let the vehicle roll backward while the shift lever is in a driving posi-
tion, or roll forward while the shift lever is in R.
Doing so may result in an accident or damage to the vehicle.
● Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift lever to a driving position while the vehicle is moving
backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Shifting the shift lever to N while the vehicle is moving will disengage the
hybrid system. Engine braking is not available when N is selected.
● Be careful not to shift the shift lever with the accelerator pedal depressed.
Shifting the shift lever to any position other than P or N may lead to unex-
pected rapid acceleration of the vehicle that may cause an accident and
result in death or serious injury.
■ If you hear a squealing or scrapi ng noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is stopped
● Do not depress the accelerator pedal unnecessarily.
If the shift lever is in any position other than P or N, the vehicle may accel-
erate suddenly and unexpectedly, causing an accident.
● Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indicator is
illuminated, and apply the parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combusti\
ble
material is nearby.

NOTICE
■Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 501)
■ When encounterin g flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, etc.
● Lubricant condition of the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
