YARIS_F (including HV)_WE_52C79E
CAUTION
Except hybrid vehicle: Shifting the shift lever to N while the vehicle is mov-
ing will disengage the engine from the transmission. Engine braking is not
available when N is selected.
Hybrid vehicle: Shifting the shift lever to N while the vehicle is moving will
disengage the hybrid system. Engine braking is not available with the
hybrid system disengaged.
Except hybrid vehicle: During normal driving, do not turn off the engine.
Turning the engine off while driving will not cause loss of steering or brak-
ing control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop
the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 650
Hybrid 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, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop
the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 650
Use engine braking (downshift [except hybrid vehicle] or shift position B
[hybrid vehicle]) 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. 253, 256, 260)
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 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 that can cause accidents,
resulting in death or serious injury.
Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.

YARIS_F (including HV)_WE_52C79E
NOTICE
When parking the vehicle (vehicles with a hybrid transmission or a
Multidrive)
Always shift the shift lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is acci-
dentally depressed.
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.
Diesel engine only: Make sure to idle the engine immediately after high-
speed driving or hill climbing. Stop the engine only after the turbocharger
has cooled down.
Failure to do so may cause damage to the turbocharger.
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 vehicle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds or vibrations.
The vehicle will lean abnormally.

322 2-4. Using other driving systems
YARIS_F (including HV)_WE_52C79E
The Stop & Start system protection feature
Vehicles without a smart entry & start system:
When an excessively loud sound is being projected by the audio system, the
audio system may be automatically cut off in order to maintain power for the
Stop & Start system function.
If this occurs, turning the engine switch to the “LOCK” position then to the
“ACC” or “ON” position re-enables the audio system.
Vehicles with a smart entry & start system:
When an excessively loud sound is being projected by the audio system, the
audio system may be automatically cut off in order to maintain power for the
Stop & Start system function.
If this occurs, turning the “ENGINE START STOP” switch off then to ACCES-
SORY mode or IGNITION ON mode re-enables the audio system.
Steering wheel operation
When the engine is stopped by the Stop & Start system, the steering wheel
may become heavier than when driving.
Hood
If the hood is opened while the engine is stopped by the Stop & Start system,
the engine cannot be restarted by the Stop & Start system or by the auto-
matic engine start function. Restart the engine with the engine switch opera-
tion. (P. 224, 228)
Vehicles with a Multidrive: If the hood is opened while the engine is stopped
by the Stop & Start system and the shift lever is in N or P, the engine will
restart.
Hill-start assist control (vehicles with a Multidrive)
On a steep uphill grade, the vehicle may roll backward after hill-start
assist control is released. In this situation, apply the parking brake and
operate the brake pedal when putting the vehicle in motion.
This system operates on flat surfaces as well as steep grades.
When the engine is stopped due to Stop & Start system operation, the
force required to depress the brake pedal may change, but this is not a
malfunction.
When to use the Stop & Start system
Use the Stop & Start system when stopping the vehicle temporarily at red
lights, intersections, etc. When stopping the vehicle for a longer period of
time, turn off the engine completely.
