E00619000087
On slippery surfaces, the traction controlfunction prevents the drive wheels from spin-ning excessive, thus helping the vehicle tostart moving from a stopped condition. It alsoprovides sufficient driving force and steeringperformance as the vehicle turns while press-ing the acceleration pedal.
E00619101098
The stability control function is designed tohelp the driver maintain control of the vehicleon slippery roads or during rapid steering
maneuvers. It works by controlling the Plug-in Hybrid EV System output and the brake oneach wheel.
E00619201578
The ASC is automatically activated when theoperation mode is put in ON. You can deacti-vate the system by pressing down the “ASCOFF” switch for 3 seconds or longer.When the ASC is deactivated, the indica-tor will turn on. To reactivate the ASC,momentarily press the “ASC OFF” switch;the indicator is turned off.
CAUTION zDo not over-rely on the ASC. Even the ASCcannot prevent the natural laws of physicsfrom acting on the vehicle.This system, like any
other system, has lim-
its and cannot help you to maintain tractionand control of the vehicle in all circum-stances. Reckless drivi
ng can lead to acci-
dents. It is the driver’s
responsibility to drive
carefully. This means into account the traffic,road and environmental conditions. zBe sure to use the same specified type andsize of tyre on all 4 wheels. Otherwise, theASC may not work properly. zDo not install any aftermarket limited slipdifferential (LSD) on your vehicle. The ASCmay stop functioning properly.NOTE
zAn operation noise may be emitted from thePlug-in Hybrid EV System compartment inthe following situations
. The sound is associ-
ated with checking the operations of theASC. At this time, you may feel a shockfrom the brake pedal if you depress it. Thesedo not indicate a malfunction.•When the operation mode is put in ON.•When the vehicle is driven for a while afterthe Plug-in Hybrid EV System is turned on.
zWhen the ASC is activated, you may feel avibration in the vehicle body or hear a whin-ing sound from the Plug-in Hybrid EV Sys-tem compartment.This indicates that the system is operatingnormally. It does not indicate a malfunction. zWhen the anti-lock brake system warninglamp is illuminated, the ASC is not active.

CAUTION zFor safety reasons, th
e “ASC OFF” switch
should be operated when your vehicle isstopped. zBe sure to keep the ASC on while driving innormal circumstances.NOTE
zWhen moving out of mud, sand or freshsnow, pressing the accelerator pedal may notallow the Plug-in Hybrid EV System outputto increase. In such situations, temporarilyturning off the ASC with the “ASC OFF”switch.Refer to “If your vehicle becomes stuck insand, mud or snow” page 9-22. zUsing the “ASC OFF” switch turns off boththe stability control function and the tractioncontrol function. zIf you continue to press the “ASC OFF”switch after the ASC is turned off, the “mis-taken operation protec
tion function” will
activate and the ASC will turn back on.
ASC operation indicator or ASC OFF indicator
-ASC operation indicatorThe indicator will blink when theASC is operating.
-ASC OFF indicatorThis indicator will turn on when theASC is turned off with the “ASCOFF” switch.CAUTION zWhen indicator bli
nks, ASC is operating,
which means that the road is slippery or thatyour vehicle’s wheels are beginning to slip.If this happens, drive slower with less accel-erator input. zIf the temperature in the braking system con-tinues to increase due
to continuous brake
control on a slippery road surface, the indicator will blink. To prevent the brakesystem from overheating, the brake controlof the traction control function will be tem-porarily suspended.The Plug-in Hybrid EV
System control of
the traction control function and normalbrake operation will not be affected. Parkyour vehicle in a safe place. When the tem-perature in the braking system has comedown, the indicator w
ill be turned off and
the traction control function will start operat-ing again.
NOTE
zThe indicator may turn on when you startthe Plug-in Hybrid EV System. This meansthat the battery voltage momentarily droppedwhen the Plug-in Hybrid EV System wasstarted. It does not indicate a malfunction,provided that the indicator goes out immedi-ately.

When the ACC no longer detects any vehiclein front, a buzzer sounds and the symbol ofvehicle running ahead disappears from thescreen. The vehicle is slowly accelerated toresume the set speed and continues running atthat speed.

While the ACC is active, if your vehicleapproaches too closely to a vehicle in frontbecause the ACC cannot allow for an ade-quate deceleration in such cases as rapid
deceleration of the vehicle in front or appari-tion of a vehicle cutting in front of your vehi-cle, the ACC gives a warning by sounding abuzzer and displaying a message.If this happens, increase the following dis-tance by depressing the brake pedal or mak-ing other decelerating control.
CAUTION zNever leave the vehi
cle during stopping by
automatic braking.WA R N I N G zYo u r v e h i c l e m a y a c c e l e r a t e u p t o t h e s e tspeed in the following situations. Applythe brake, if necessary, to slow down.
•When your vehicle no longer follows thevehicle in front, e.g. at a freeway exit orwhen your vehicle or the vehicle in frontchanges its lane.•When driving on a curve. zIf the vehicle in fron
t turns off or changes
lane and another stationary vehicle islocated in front of that vehicle, the ACCwill not make deceleration control to thestationary vehicle.

CAUTION zWhen the ACC is not in use, turn off the sys-tem to prevent it from operating by mistakeand an unexpected accident. zNever operate the A
CC from outside the
vehicle. zNeither control nor a warning are performedby the following situation.•Something other than vehicle such as apedestrian.•When there is abnormality in the system(When the ACC detected abnormality,“ACC SERVICE REQUIRED” is indi-cated.)
