1584-2. Driving procedures
AYGO_EE_OM99J92E
WARNING
■ When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting in
death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 2 seconds, or press it briefly
3 times or more in succession. ( →P. 343)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine 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.
NOTICE
■ To prevent battery discharge
● Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.
● If the smart entry & start system indicator light (green) is illuminated, the
engine switch is not off. When exiting the vehicle, always check that the
engine switch is off.
■ When starting the engine
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked immediately.
■ Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional immediately.

AYGO_EE_OM99J92E
■ Automatic reactivation of the Stop & Start system
Vehicles without a smart entry & start system: Even if the Stop & Start system
is disabled by the Stop & Start cancel switch, it will be automatically re-
enabled once the engine switch is turned to the “LOCK” position then to the
“START” position
Vehicles with a smart entry & start system: Even if the Stop & Start system is
disabled by the Stop & Start cancel switch, it will be automatically re-enabled
once the engine switch is turned off then the engine is started.
■ The Stop & Start system protection feature
Vehicles without a smart entry & st art system: When an excessively loud
sound is being projected by the audio system, the audio system may be auto-
matically cut off in order to maintain power for the Stop & Start system func-
tion.
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 automati-
cally cut off in order to maintain power for the Stop & Start system function.
If this occurs, turning the engine switch off then to ACCESSORY 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 the automatic
engine start function. Restart the engi ne with the engine switch operation.
( →P. 151, 154)
■ When to use the Stop & Start system
Use the Stop & Start system when stopping the vehicle temporarily at red
lights, intersections, etc. When stoppi ng the vehicle for a longer period of
time, turn off the engine completely.
■ Stop & Start system warning buzzer
If the engine is stopped by the Stop & Start system and the following action is
performed, a buzzer will sound and Stop & Start indicator will flash. This indi-
cates that the engine is only stopped by the Stop & Start system, not that the
engine has been turned off completely.
● The shift lever is shifted into a position other than N with the clutch pedal
released.
Even in this situation, the engine starts if the clutch pedal is depressed.

Driving
AYGO_EE_OM99J92E
Driving assist systems
◆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) (if equipped)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆TRC (Traction Control) (vehicles with a VSC system)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆Hill-start assist control (vehicles with a VSC system)
Prevents the vehicle from rolling backward when starting on a
incline or slippery slope.
◆Emergency brake signal
When the brakes are applied suddenly, the emergency flashers
automatically flash to alert the vehicle behind.
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.

AYGO_EE_OM99J92E
WARNING
■ If the engine has to be turned off while driving
● Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Vehicles without a smart entry & start system: Never attempt to remove
the key, as doing so will lock the steering wheel.
