AYGO_OM_Europe_OM9A012E■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 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.

WARNING
■When the Stop & Start system is operating
● Keep the shift lever in N and apply the brake pedal or parking brake for
safety while the engine is stopped due to the Stop & Start system (while
the Stop & Start indicator is on).
Unexpected accidents may occur due to the automatic engine start func-
tion.
● Do not leave the vehicle while the engine is stopped due to the Stop &
Start system (while the Stop & Start indicator is on).
Unexpected accidents may occur due to the automatic engine start func-
tion.
● Ensure that the engine is not stopped by the Stop & Start system while the
vehicle is in a poorly ventilated area. The engine may restart due to the
automatic engine start function, causing exhaust gases to collect and
enter the vehicle and resulting in death or a serious health hazard.

■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
●Vehicles with a multi-mode manual transmission: The shift lever is in a posi-
tion other than N (when starting off forward/backward on an upward incline)
●Vehicles with a manual transmission: The shift lever is in a position other
than R when starting off forward on an upward incline, or the shift lever is in
R when starting off 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:
●Vehicles with a multi-mode manual transmission: The shift lever is shifted to
N
●Vehicles with a manual transmission: The shift lever is shifted to R when
starting off forward on an upward incline, or the shift lever is shifted to other
than R when starting off backward on an upward incline
●The accelerator pedal is depressed
●The parking brake is engaged
●2 seconds at maximum elapsed after the brake pedal is released
■Sounds and vibrations caused by the ABS, brake assist, VSC, TRC and
hill-start assist control systems
●A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. 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 also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.

2824-6. Using the driving support systems
AYGO_OM_Europe_OM9A012E■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
re-enabled in the following situations:
●When the engine switch is turned to the “LOCK” position (vehicles without a
smart entry & start system) or off (vehicles with a smart entry & start sys-
tem).
●If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■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 engine off. The
EPS system should return to normal within 10 minutes.
■Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
●The emergency flashers are off
●Actual vehicle speed is over 55 km/h (35 mph)
●The brake pedal is depressed in a manner that cause the system to judge
from the vehicle deceleration that this is a sudden braking operation
■Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
●The emergency flashers are turned on
●The brake pedal is released
●The system judges from the vehicle deceleration that is not a sudden brak-
ing operation

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire

Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
*: Tire chains cannot be mounted on the 15-inch tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
