PRIUS_U_(L/O_0802)
CAUTION
■When driving the vehicle
● Do not under any circumstances shift the shift lever to “R”, “N” or push the
“P” position switch while the vehicle is moving.
Doing so can cause significant damage to the transmission and may result
in a loss of vehicle control.
● Do not shift the shift lever to “N” while the vehicle is moving.
Doing so may cause the engine brake not to operate properly and lead to
an accident.
● Do not turn the hybrid system off while driving.
The power steering and brake actuator will not operate properly if the
hybrid system is not running.
● Use engine braking (“B”) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 136)
● When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.
● Do not adjust the position 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 that can cause accidents
that may result in death or serious injury.
● Always check that all passengers’ arms, heads or other parts of their bod-
ies are not outside the vehicle, as this may result in death or serious injury.
● 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 high
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.

When driving
PRIUS_U_(L/O_0802)
CAUTION
■
When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
● Sudden changes in engine speed, such as engine braking caused by
upshifting or down-shifting, may cause the vehicle to skid, resulting in an
accident.
● 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, resulting in
an accident.
■ 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.
■ When the vehicle is stopped
● Do not race the hybrid system.
If the vehicle is in any gear other t han “P” or “N” the vehicle may acceler-
ate suddenly and unexpectedly, and may cause 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.
● Always keep a foot on the brake pedal while the hybrid system is running
to prevent an accident caused by the vehicle moving.
